Transcript:
Rachel: Welcome to Let's Talk About CBT Practice Matters, the BABCP podcast for therapists using Cognitive Behavioural Therapy with me, Rachel Handley. Each episode we talk to an expert in CBT who will share insights that will help you understand and apply CBT better to help your patients.
Today, I'm really delighted to say we're joined by Dr. Rebecca Murphy, clinical psychologist and senior research clinician at the University of Oxford, specialising in CBT for eating disorders and its dissemination.
Welcome, Becky. It's really lovely to have you on the podcast. Thanks so much for joining us.
Rebecca: Thank you so much, Rachel. It's such a pleasure to be here, and to be part of this really interesting series that you've put together.
Rachel: Becky, we go back a few years, right? We probably even unknowingly crossed paths in the psychology department when we were undergraduates overlapping. But ever since I've known you properly when we embarked on our clinical psychology training, you've been really interested and passionate about eating disorders. I'm wondering what got you interested enough in the field, personally, professionally to pursue this as essentially your life's work?
Rebecca: Yeah, thank you so much, Rachel and it's lovely to be speaking with you, as we have known each other for such a long time. So, I guess my interest started with mental health generally, and probably I had an interest from a very early age compared to most people, because my father was actually director of a therapeutic residential community for people with severe and enduring mental health difficulties. And as a director, he actually had to live on site, so I actually grew up surrounded by people with various mental health problems, seeing the impact it had on people's lives and being able to observe the difference that support and care made. I carried this through and that's why I studied psychology as an undergraduate. And within my course, we looked at different areas of mental health and I was very interested in eating disorders and what I especially loved was their complexity and the multifactorial elements. So as with many other areas, they're sort of no single cause. Yeah, you're thinking about biological, psychological, social factors. But I think with eating disorders, it's a really nice example of how all of those elements come together. So that was kind of my early interest. And I wanted to do something that would really make a difference, and I felt as if eating disorders as a field is actually still relatively young compared to some other psychological disorders so I really thought, Oh, I've got an opportunity potentially to make a big difference, as a researcher and clinician, in terms of thinking about new approaches, new ways of understanding eating disorders. And when I started to work with people, I also loved seeing how much people could change. So I really felt that it was an area in which there's so much hope because most people do get better and that was really rewarding to be part of. So yeah. That's where it all started.
Rachel: And do you think that desire to make a difference, and that sense of hope was rooted in those early experiences that you had of living in that community? Did you see people's lives change, impacted there?
Rebecca: Yeah, I think I did. I suppose I saw two things. One, if it's part of your everyday environment, it's very de-stigmatising, so you just see how normal it is for all of us at some point in our lives to have various difficulties, and I think I didn't really see it as something separate or that it was something that made people fundamentally different. I just saw it as part of a sort of continuum, that maybe we're all on. And I did, I saw people change. I mean, not necessarily the parts of them which they appreciated and valued but I could see that when people were really suffering, that was something that if you provided people with care and support, they were able to come out of and then they were able to make changes in their lives in terms of what they wanted, in terms of living independently or no longer being in such a state of distress.
Rachel: So you could say that mental health has been part of your experience in terms of your genetics, your social environment and your psychological interest yourself throughout your life then.
Rebecca: Definitely. So for me it was an everyday conversation from a really young age.
Rachel: And I know you're interested not only in the what or process of treatment for eating disorders, but you're also interested in how we deliver therapy to make treatment more accessible and widely available. And we'll get into some of the great work you've been doing in that area. But given this is a young field as you've alluded to and there's probably still a lot of work to be done, how easy is it for folk who need access to good evidence-based treatment for eating disorders to access that?
Rebecca: It is such an important question and unfortunately there is, as is the case in other fields as well, but there's a huge treatment gap between the number of people who could really benefit from treatment and the number of people who actually receive it. And perhaps there are two, two major sources of this treatment gap. One is that often people with eating disorders, they feel a sense of stigma or shame surrounding the problem so people may delay seeking help or never seek help because they don't feel able to disclose it to someone and so that's sort of an internal barrier. And then externally other barriers include that there is really only a limited number of trained therapists to be able to help people with eating disorders. So even when people do come forward and seek help, there aren't enough specialists to meet demand. And I mean, that's true even in kind of wealthy developed countries, and we know that only a small percentage of people with eating disorders receive recommended treatments.
Rachel: So it's that double whammy of actually, it's really hard to get yourself to therapy because of that stigma, because of those barriers, and then you get there and you might not even be able to access it, so a lot of work to be done there.
Rebecca: Yeah, absolutely. So it's a really difficult journey for people. Another barrier is often that people might present for help, but due to a lack of training, quite often primary care staff, so people sort of GPs and other individuals at the first point of contact, they aren't trained well enough to easily be able to recognise eating disorders as well. So people can get missed, misdirected or dismissed and if they even make it through that barrier, they might have to wait years to get treatment if they're even offered any, many eating disorder services are so limited that they can only offer treatment to people that are considered to be at very high risk, so other people just get turned away.
Rachel: And the term eating disorders covers a really wide range of clinical presentations. I wonder if you can tell us a little bit about maybe some of the unifying characteristics of eating disorders and also aspects that might differ diagnostically, and what we know about typical presentations our listeners might see day to day in clinical practice.
Rebecca: Yeah, that's a great topic to consider and I really liked how you started with asking about unifying factors because it's something that our research group at the Centre for Research on Eating Disorders at Oxford, our position is that we're more interested in features or characteristics of eating disorders rather than diagnoses. And quite often you do have these shared or unifying characteristics, which are quite specific to the eating disorders, but are shared across the group. And one of those characteristics is what we call an over evaluation of shape and weight and eating, which is where people's sense of self-worth depends largely or exclusively on their ability to feel like they're doing well in the areas of eating, weight and shape. So often people might be feeling bad about themselves as a person because they feel that they're not able to do well in those areas, which are very much informing their sort of sense of self-worth. So this is quite a unifying characteristic across most eating disorders, but not at all. And quite often this characteristic drives other features of eating disorders that we see. So for example, if you are feeling that in order to be worthwhile as a person that, in terms of the areas of, for example, weight and shape, it quite often means that people end up developing strict rules about their eating. So this is where perhaps they have certain foods, which they do not allow themselves, they may set calorie limits. And these rules need to be followed, because they are rules, and that leads people sometimes to go on to actually eat a restricted amount of food which may mean that they develop being a lower weight or in some cases what can happen as well is because the rules are so strict, it actually causes them to have episodes of binge eating, where they lose control and eat an unusually large amount of food. And that's through a couple of mechanisms, including feeling as if they’ve broken the rules because often these rules are so difficult and demanding that it's almost inevitable they get slightly broken and that can trigger a “well, I've sort of messed up a bit, I might as well give in completely”. And also people get very hungry and in a state of psychological deprivation. So they're sort of craving and drawn to the very foods that they've banned themselves from having and people often feel incredibly distressed and guilty, as a result, and this reinforces their desire to want to diet more and be more concerned about their shape and weight, and they get stuck in that cycle. And so that's kind of one element and then we also have another sort of feature around eating disorders is that people are using eating in some way to try to cope with difficult or intense mood states or problems in their life as well. So that's another kind of characteristic feature amongst eating disorders.
Rachel: And, in terms of the kind of labels we might put on these kind of presentations diagnostically, and I hear what you're saying, kind of there are these trans diagnostic features, these unifying features, what are the kind of presentations people might hear about, see, be intervening with in clinical practice?
Rebecca: So probably the three most well-known eating disorders are Anorexia Nervosa, where people restrict their eating and become a low weight. Bulimia Nervosa, where people also judge their self-worth in terms of wanting to control eating shape and weight, and they will also diet, but at the same time they have episodes of binge eating and they may make themselves sick as well. And then there is Binge Eating Disorder which is where people have regular episodes of binge eating, feel very distressed about that, but they don't engage in the set of compensatory behaviours we see in bulimia nervosa, and the compensatory behaviours are fasting or making themselves sick those sorts of things. So they're the three most well-known. But then there's a group of what we might call other or atypical, which are still above the clinical threshold, but they don't quite meet the exact set of criteria of the other disorders.
Rachel: So they're still distressing, they're still interfering with people's lives, and they're focused on these kinds of behaviours, but maybe don't quite fit the mould.
Rebecca: Yeah, absolutely.
Rachel: And what do we know about how significant a problem these eating disorders are population wide?
Rebecca: Yeah. so actually eating disorders are, as well as sort of being severe, they are relatively common as well. There was a systematic review in 2019, which estimated that over 100 million people worldwide are currently experiencing an eating disorder. And in terms of kind of population estimates or how often over the course of somebody's lifetime they might experience an eating disorder, the most common eating disorder is binge eating disorder. So that affects around sort of 2-5% of the population of people over their lifetime, many cases go undiagnosed. Bulimia nervosa has a lifetime prevalence of around 1-2%. And the rarest eating disorder is anorexia nervosa, even though it's often the most well-known and the most perhaps visible on the surface level and that affects around half to sort of 1 percent of the population. And that's in terms of eating disorders above a clinical threshold whereas we also know that many people have disordered eating or eating problems below that threshold as well.
Rachel: And I imagine there's a bit of overlap and people move from maybe one presentation to another over the course of their lifetime or the period of their eating related problems.
Rebecca: Absolutely, yes and that diagnostic migration, where people may perhaps begin their eating disorder journey, meeting the criteria for anorexia nervosa, which could evolve over time. And another time that you see that person, they might be experiencing criteria, which is consistent with bulimia nervosa. That diagnostic migration is common and that's one of the reasons that our research group take a more transdiagnostic approach to understanding and treating eating disorders, because it doesn't really make sense to us if we were to see someone one week and it looks like they meet the threshold for one disorder and we seen them a week later, they meet the threshold for another disorder, to suddenly change our treatment approach based on that kind of fluid progression. It makes more sense, in our view, to take a trans diagnostic approach where we're really interested in what are those kind of unifying features which tend to be quite specific to eating disorders and we match and map our treatment onto those features rather than a diagnosis.
Rachel: And potentially much more meaningful and helpful to those individuals as well.
We're coming up to Eating Disorders Week in the UK towards the end of February and I've seen statistics on the BEAT website where they talk about the theme of the week is anyone can be affected by an eating disorder, and really those statistics do speak to that. And they talk about 1 in 50 perhaps in the UK experiencing these kind of presentations at some point in their life, which is really, it's huge isn't it, and speaks to the importance of the work you're doing.
And in our culture, in Western culture, there is such a strong emphasis on the importance of weight and shape. It is actually hard to fathom sometimes why any of our young people grow up with a healthy, happy body image. We were just catching up on our kids, before we started recording and talking about my youngest, my seven-year-old daughter. And I was really shocked in this last week when she suddenly announced that she was fat and had a fat tummy. I'm really taken about where that come from, as it didn't come from chatter or talk around the house. And you hear these narratives so quickly in young people's lives. But obviously there's something about the kind of presentations you've been talking about, that some folk go on to really get trapped into this very single minded focus on weight and shape. Given the range of presentations, you've talked about these fluid presentations, the overlapping presentations, is it possible to identify a typical pathway into eating disorders? How does someone go from a feeling that they've got a fat tummy to this kind of overvalued sense of identity in their weight and shape?
Rebecca: Yeah, that's a good question and I appreciated your lead up to that in terms of thinking about, how common it is and how worrying it is as parents and members of society to see our young people just start to exhibit essentially eating disordered type behaviours and thoughts, from such an early age, even if they don't meet the sort of diagnostic threshold. And actually studies have found that it could be sort of around one in five children and adolescents worldwide do exhibit these sorts of eating behaviours, which is really very common. In terms of the sort of pathway I guess every individual's journey is different, but there will be contributing factors. So there are certain risk factors that make some people more vulnerable to developing eating disorders, and essentially one of the biggest risk factors for eating disorders is something which many people engage in which is dieting. And for some people they can navigate that, they can sort of diet in a way that it doesn't dominate and take over their lives. But for some people, what starts as perhaps less sort of harmful dieting can really develop into something where people start to feel that the eating disorder is controlling them rather than the other way around. And sometimes you get a perfect storm of factors, so it might be, for example, I mean it's different for everyone, that somebody starts dieting, maybe they feel that generally other elements of their life are not in their control, so they get quite a sense of control because they're eating and perhaps early on is something they feel that they can control and change. Maybe they have an influence on the number on the scales, maybe they've had times in their life when they've been bullied or treated in a way or exposed to some kind of trauma which makes them feel bad about themselves, which makes them feel bad about their body. Maybe they get some positive feedback, sadly, from people on sort of you know, dieting or losing weight because of the weight stigma and our culture which values restriction. And maybe they then also have some difficulties in their life, which they then turn to controlling eating disorders to cope with. The sort of dieting pathway is quite a common pathway and perfect storms are created by maybe having some other things in the background, perhaps some triggering factors, perhaps there's a relationship breakup, loss of a job, some kind of trigger which presses people's buttons in terms of feeling bad about themselves and feeling like their life's out of control.
And for other people, it could look quite different. They could be younger or older. I mean eating disorders could happen at any age. They could be older, they could be middle aged, and they could be someone who has always perhaps turned to food when they felt low, or as a way to deal with difficult feelings, but they start to do that more and more and maybe they sort of feel that they're trying to diet as well, that sort of out of control binge eating could happen. So yeah, there are lots of different ways into it.
Rachel: I'm really struck by that as a getting older woman myself, that even in those environments where when you were younger, you might get positive feedback for losing weight, but also there might be some sense of, oh you don't need to diet or we shouldn't be dieting, whereas you get to sort of a certain age and it's completely normal to be on a diet or to be talking about time restricted eating or different types of whatever the latest fad is. I wonder, do you see interactions with other sort of fads and trends, like for example, we see the new sort of generation of weight loss drugs, like Ozempic, it’s all over the news and in celebrity chats. Do these things affect, interact with eating disorders in the presentations you see?
Rebecca: Yeah, absolutely. So these kind of new weight loss drugs are having quite a major impact on eating disorders. Probably not clear exactly, how much at the moment, but I think they definitely are having an impact. These sort of types of drugs tend to work by reducing appetite, slowing down digestion, which essentially means people eat less and lose weight. But for people with eating disorders or a history of disordered eating, these medications can be potentially quite risky. If you think about the appetite suppression risk, so if people have reduced sense of hunger, it makes it easier for them to skip meals, easier to eat little and that can have quite negative consequences in terms of increasing people's risk of going down that pathway around strict dieting and not feeling that they can eat normally. And that can trigger binge eating cycles, especially when with quite often with these drugs, people are not able to take them for a sustained period of time, kind of forever, they're taking them for a period of time and then they're coming off them so that, can be really difficult in terms of triggering problems.
Rachel: You've said about the importance of control often in these presentations, you get a sense of this is under control, I can do this, I can go further and then the drug goes.
Rebecca: Exactly. And then there's a change in people's weight, which can be quite distressing for people. So I think it's very difficult. And I think the other way in which I see harm is because they turn the conversation essentially onto the topic of eating, weight and shape. And I mean the conversation in terms of what we talk about in our real life, what's spoken about on social media, the attention, the kind of space that is given to these topics, the amount of coverage of celebrities who've lost weight. We've got such a narrative now around what I think already was a really harmful idea, which is that this idea that anyone can just change their sort of body shape and size dramatically and that's kind of a really unhelpful fallacy. But sadly, I feel like these drugs are just reinforcing that.
Rachel: Really unhelpful, isn't it? And I can imagine it's so much harder to convince someone that really the world isn't judging them on the basis of their weight and shape when that's so much of the narrative that's out there. And some of the best developed work in CBT for eating disorders that your group has done historically has been with bulimia nervosa. And that work, as you've alluded to, has been extended and enhanced to provide an understanding of the maintenance of and treatment of eating disorders across the board in this kind of overlapping picture we've been speaking about. Can you tell us a little bit more about this journey and our understanding?
Rebecca: Our research group has been around for longer than I've been working in this role, and I want to acknowledge Christopher Fairburn and Zafra Cooper who played such a major role in really developing these psychological treatments. Originally, the treatment that we specialise in called Enhanced Cognitive Behaviour Therapy, or CBT-E, started life as CBT for bulimia nervosa back in, I think, sort of 1981 or something. And so that model was essentially a theoretical model and treatment approach for one eating disorder, bulimia nervosa, and the characteristics involved in that eating disorder. And that treatment was pretty effective, but I think it was probably around half of people who received it didn't get better and Chris Fairburn and Zafra Cooper, Roz Shafran and colleagues, what they did was took the approach of really trying to understand why it was that some people didn't get better. And, as a result of that investigation and exploration, they added more to that original model and expanded it.
So one area that was very interesting is they found that for some of the people who didn't get better with that original version of the treatment, they actually had some difficulties almost sort of outside of the eating disorder, outside of that very kind of focused model and that included clinical perfectionism, core low self-esteem, we definitely see low self-esteem in people with eating disorders, but a really sort of deep seated core belief about feeling bad, interpersonal difficulties and essentially they expanded the model so as to allow for the inclusion of these broader, more external factors. So that was one way that they increased the potency of the treatment. They also expanded diagnostically outside of bulimia nervosa to take this transdiagnostic approach. So what they did was created a treatment that was suitable for people with all types of eating disorders, including anorexia nervosa, by adding in additional modules that were needed to be able to expand the treatment and create more of a sort of general trans diagnostic template understanding, that could then be applied to anyone with an eating disorder. And they also sort of really looked carefully at some other aspects which weren't originally considered in the treatment. And that included, for example, body shape checking which is something that often people who are very concerned about their shape and weight engage in behaviours to try and sort of check their weight, maybe looking in the mirror or pinching or feeling their bones. And actually, in the expanded version of the treatment, enhanced version, they included a therapeutic procedure dedicated to addressing shape checking, as it's quite a major maintaining mechanism or feature which tends to contribute to people's concerns that they have about their body.
Rachel: So thinking then about the factors drawing together what we've been speaking about the development, the vulnerability, the risk factors, these factors that keep the disorders going. You may or may not know we have a challenge on this podcast. I know you do know that we love a good formulation in CBT, usually it has boxes and arrows and is drawn up in a whiteboard or similar or online. But this is an audio podcast. So here's our challenge. Can you give us a brief explanation about how eating disorders develop and are maintained without repetition, hesitation, deviation, boxes, arrows, or other visual aids. Is this possible, Becky? Are you up to the challenge?
Rebecca: I will accept the challenge and I will hope that I can deliver. I would like to start by saying that the approach that we tend to take when we actually work with patients is that we don't use jargon, so we actually prefer to call the formulation a diagram and we tend to always start drawing the diagram collaboratively with our patient by, first of all, beginning with what it is that someone most wants to change. So this means that everybody's diagram maybe starts in a different place and it would start with their own kind of words to describe it. But I can give you one kind of version. So, it's quite common that people say that they would like to perhaps change their binge eating, if they're binge eating but if someone isn't binge eating, they may often begin by saying they'd like to change how upset and distressed they are about their body, for example.
So, if we imagined we started there and this is what we often consider quite a core factor, almost a driving factor behind many eating disorders is the way in which people judge their self-worth in terms of their ability to succeed in or control their eating, weight and shape. We could imagine that this begins at the start of the journey. So people are very concerned about their shape and weight and they really feel bad about themselves as a person if they're not controlling or doing well in those areas. And naturally leading on from this, you might see that this could lead to strict dieting; in order to control my shape and weight and eating, what I must do is follow this set of rules. And perhaps these are things that you've been told in the media that you shouldn't eat, or calorie limits you should stick to if you want to lose weight. And so people might start restricting their eating, that might get more extreme, which could mean that people develop being a low weight. And when people are a low weight that often comes with certain side effects, such as being preoccupied with food, feeling incredibly full from eating a small amount of food, losing interest in the outside world and quite often these side effects serve to really reinforce the concerns that someone has about their shape and weight and the need to diet. They think, well, I'm feeling full, I've only had a tiny amount I must've overdone it. Or I'm not really that interested in anything else in the world anymore, except what’s going through my mind about eating, shape and weight so that, that's what I'll focus on. So people can get stuck in a sort of vicious cycle there. And, or, if this might also happen, they might find that because they're really trying to control their eating and engage in this strict diet that they lose control of their eating and start to binge eat in the way that I described earlier, either through kind of hunger and cravings or through feeling like inevitably they break their rules, they feel they've failed, they give up control. And then when this happens, they think, wow, I need to really double down on my rules. I must be even stricter. Makes them even more concerned about the shape and weight and they get stuck in that cycle. And binge eating doesn't just come out of the blue, typically it happens in response to difficult or intense feelings that people have or things that happen in their life. And so there's a sort of another pressure, and that pressure can also put people under pressure to want to diet more in response to difficulties in their life. It could make people want to make themselves sick. Different eating behaviours can help to modulate or change people's mood. It can distract them, it can take their mind off things that they don't want to deal with in their life. But then of course those problems build up because people aren't dealing with them in their life. They're perhaps using these sort of unhelpful coping strategies, so you get another kind of vicious cycle there. So I hope that's illustrated some of what we believe is relevant to understanding eating disorders.
Rachel: That was an excellent summary of lots of very complex processes there. And as you say, lots of different cycles going on. But with this kind of core idea, this over evaluation of weight and shape leading to these kind of behaviours around restriction and restraint, which then have this cascade of effects; the preoccupation with food, with how our weight and shape is doing, and the kind of narrowing of focus, which then, you know, kind of feeds back in or maybe we fail and we double down and maybe there's external pressures ramping up the pressure to control and creating further preoccupation with that and leading to other behaviours that might again be having sort of negative feedback into the loop. A lot of different directions I can see that people can go, but all cascading from this central preoccupation. And as we see across the disorders, I guess, these often self-defeating strategies to try and achieve those central goals.
Rebecca: Yeah, absolutely. I mean, dieting is often seen, for example, as a solution to binge eating but in fact it's a major perpetuating factor. It's actually driving a lot of binge eating.
Rachel: And given these factors that are, these drivers and these common factors that we're seeing, what are the key elements of enhanced CBT for eating disorders and how do they link to these maintenance factors?
Rebecca: Yeah. So we could think of, and this isn't my analogy, I think this is an analogy of Chris Fairburn and his other colleagues, but eating disorders as being a bit like a house of cards. If you've ever sort of made one of those as a child, where you try to create this kind of structure with playing cards. And if you think of an eating disorder as a bit like that sort of structure, what you're trying to do in therapy and our sort of CBT-E therapy is you're trying to take out the key cards that are keeping the eating disorder in place. So you're mapping your treatment strategies and procedures onto exactly those maintaining mechanisms and you're trying to quite strategically pull those cards out. The first thing that you do in treatment, we call it starting well, which is stage one and essentially that's a bit like laying the foundation, I think, for a lot of the rest of treatment because you help people to have a better understanding of their own eating disorder, to become more aware of what they're doing in real time so that they can make changes. And you pull out quite a major card and that is, use an intervention which sounds simple but is quite complex in terms of the repercussions and what it changes in the structure and that's where you introduce regular eating. Quite often people come to treatment with large gaps as they're skipping meals or skipping snacks, or they might have quite chaotic eating habits or ways of eating. And they don't have a kind of structure of times when they eat and when they allow themselves to eat. So one of the sort of key elements that we put in place is trying to change that, and that seems to pull out some quite key cards in the eating disorder. So you're disrupting that long period of time people are going without eating, and essentially helping people to be able to eat which is the kind of major part.
Rachel: You say Becky, that sounds simple, but I imagine I'm coming to treatment, I am literally petrified of what goes in my mouth and the impact it's going to have on my body. It doesn't sound at all simple.
Rebecca: No, it's it sounds simple as a procedure if you sort of just say, oh, regular eating, it sounds like, what do you do in regular eating? You eat at regular intervals. But exactly as you say, it's certainly not simple for people to do. It's incredibly hard because eating is exactly the reason they've come to treatment because that's something that they find difficult. So it's not something thats easy to do. It's something that we have to help people to be able to build in that kind of structure and that has often has such a powerful effect in terms of, for example, often a rapid reduction in binge eating when people do that. It builds a foundation for people who are lower weight to then be able to add in more kind of energy into their diet. So that's kind of part of the starting process as well as people really understanding what's keeping their own eating problem going and becoming more aware of what they're doing. Quite often they might be on sort of eating disorder autopilot, just sort of going through the motions of restriction, dieting and so on but without really being aware of decisions that they might make or behaviours that they might engage in.
So once we've started well, hopefully, we then move into the second stage which is where you kind of take stock and review progress. And you think, what have we learned about eating sort of so far together? What do we now need to do in the rest of our treatment to be really sure to treat together what it is that's keeping your particular eating problem going. So you plan on the basis of this sort of taking stock stage, and you plan stage three, which is where you really try and tackle the major elements that are keeping somebody's eating disorder in place. And that part of treatment is more kind of personalised, what you do and the order of what you do would depend on the person. Quite often you're addressing body image, dietary restraint, people's rules about their eating. You might be looking at how people cope with events and moods and helping people to problem solve or find other more helpful ways of coping with mood states. If somebody's a low weight, you would be helping people to make an informed decision to regain weight and then helping them with weight regain. So that's kind of Stage three. And then at the end, you want to help somebody to stay well in the long term. So you dedicate the final part of treatment towards really trying to empower people with what they would need to know in order to stay well in the long term.
Rachel: So that's a brilliant summary of those four stages, an overview. Is it unfair to ask what a typical good course of therapy might look like? Typically, what do you do? And I'm thinking, you've spoken about getting people into regular eating. How do you persuade someone that's a good idea? And how do you address some of these other maintaining factors that we talked about?
Rebecca: Yeah, establishing regular eating, what we're doing with people is helping to perhaps be able to take a step back from their eating disorder instead of perhaps kind of living it and being in it. It's being able to kind of step back and observe it from a distance. And that's why we do draw this diagram together because we want people to be able to kind of look at their eating problem and be curious and interested in it and try and understand some of the ways in which they're behaving and thinking about things which are keeping the eating problem going. And we also engender that curiosity and kind of distance perspective through helping people to self-monitor in real time. So that's where people write down in the moment, really anything to do with their eating problem and that might be a lot of things that actually are not eating- but that could be how people are feeling, what's happening in their life, what they're thinking about, which might be a consequence of what they're doing with their eating, or they might be things that trigger difficulties with their eating. And so when they've got that sort of curiosity and that stepped back perspective, it enables them to see with you, what sorts of patterns are actually holding them back and creating problems. And so at the same time as us suggesting that they experiment with doing things differently and eating in a kind of regular planned way, they're also recognising that the way that they've been doing it, which is often by skipping meals, maybe going the whole day and then perhaps losing control later or just feeling really tired and unable to concentrate and all those sorts things and kind of recognise that, that's not really helping them. And you're coming in and you're saying, I'll be here to support you but how about doing things differently, experimenting with doing things differently? And I'm going to give you some advice on something which really does help most people with eating disorders. Why not give it a go, see if life is any better doing it this way, at this point what have you got to lose? Now for some people, they feel like they've got a lot to lose and you do have to spend time in treatment really helping them to think about whether or not they want to get better and those sorts of things. But even with regular eating, people can choose what they want to eat. It's not about saying you have to eat certain things. It's about the timing. So they're starting off by perhaps spreading out, in some cases small amount of food, but it's actually giving them that structure, and you're kind of giving people permission to eat which can be really difficult for people.And we also at this stage would involve significant others. So really quite often recommend that people invite people close to them who have an influence on them and their lives into the end of one of our sessions. And so we can think about how other people can really support them and create the best environment that will help them to be able to make the changes that we're talking about in the therapy session.
In terms of a typical stage one, it would look like quite often people making some changes like eating more regularly, binge eating would usually might go down, it's different for everyone, people starting to feel like they understand their eating disorder better. It’s not easy. I don't think with anyone, I wouldn't say it's kind of straightforward or easy and that's usually why, again, we see people twice a week in stage one, because they need that extra support to build therapeutic momentum, to not get stuck. And then, usually they have actually made some progress in stage one. There are still things that are difficult, but they can see a little bit that things can change. They're feeling a bit more hopeful but often even at that stage, there's still a lot of work to do. So we plan the rest of treatment, usually during that taking stock stage you kind of think, well, what's been difficult and everyone's different, it might be that they've had difficulties attending sessions because they have childcare issues or something external to them. Maybe they've had difficulty talking about things in the session because that's something that they find hard to do. Maybe you as a therapist think, Oh, actually, perhaps I've been doing things that haven't been that helpful. And so that taking stock stage is an opportunity for you both to put your heads together and think what do we need to work on? What might be getting in the way of change? What do we need to do for the rest of treatment? So usually that's a really important informative stage. So for most people that still coming to treatment, they're making changes.
And then the third stage can look quite different for different people, but most typically we would start by thinking about how people judge their self-worth largely in terms of shape and weight. And there are different ways that we do that. I think of it a bit like, imagine that your sense of self-worth is shown in a pie chart and each slice in the pie chart is a reflection of an area of your life that informs your sense of self-worth. So for some people it might be work that dominates, if I give an interesting talk like this podcast, if people think this is a great podcast, maybe I feel good about myself, or if it goes terribly badly, I think maybe I feel awful about myself if that's a major area on my pie chart.
Rachel: I'm sure you'll come away feeling good Becky
Rebecca: If I don't really mind and I'm not too bothered, maybe that's because there are other areas in my pie chart, which help to balance things out, which I can think, oh, well this went badly but at least I'm still doing all right, with being, I don't know, being a wife or mother or engaging in my hobbies or something like that. But for people with eating disorders quite often, it's very much, that they've got all their eggs in one self-evaluative basket, like sort of weight or shape and when they feel like that's not going well, it’s really difficult. So we get people to try and bring in other slices to their pie chart, by engaging in areas of life outside of eating, weight and shape, maybe taking up hobbies they used to enjoy, maybe thinking about what other people they know do and really trying to build a life outside of eating, weight and shape.
So it's a bit like, if you're a gardener and you put a plant in like mint and it starts to dominate and take over the garden, you've kind of got different strategies but one strategy is to surround it by other quite kind of vigorous plants which can help to squeeze it out. And that's what you're trying to do when you help people build up other areas of your life.
The other way to squeeze mint out is to sort of deprive it in terms of no longer feeding and watering it. And that's another approach we take, which is where we think, what is it that people are doing which is a natural consequence or expression of their concerns about shape and weight, but which are actually serving to keep them concerned about their shape and weight. And that might be frequently checking their body, scrutinizing themselves in the mirror, looking at parts of their body that they don't like, those sorts of things. How can we try and stop engaging in that behaviour? So sort of stop feeding and watering the over concerned slice so as to really shrink that slice of the pie char or limit the growth of that plant. So that's one approach we take with body image. And then there are the other areas, which, I've gone on now, so you might not want those, but we talked about dietary restraint, helping people regain weight, there's other elements of treatment. Hopefully, again, usually it sort of goes well to the extent that people find therapy helpful, they find change and benefits in those areas and then they stay on for the last part of treatment, which is how to stay well in the long term. And normally, at the end people maybe feel ready to end treatment. Which is great, or they feel a bit sad about ending treatment and that's okay too and we help them to feel confident about going forward and using what they've learned in therapy on their own
Rachel: That's so helpful, and I love the, where you started, you talked about stepping back, you talked about the formulation with the diagram, you joined up, and it seems to me there's this kind of overall stance of almost like zooming out, stepping back from this very narrow focus of where my identity self-worth derives from, to just seeing that bigger picture, that bigger pie, that more variegated garden. I love the mint analogy, as someone who can grow very little, but has had limited success with mint as the only plant that actually does reproduce in my garden. I can see how one might overvalue one's identity as a good mint grower, but it seems that might lead to limited positives in one's life more generally, so this is a really helpful metaphor. And you talked about how people hopefully are getting benefit from this. What do we know about the effectiveness and efficacy of CBT- E? Is it effective? Is it equally effective for everyone?
Rebecca: So I think, if we look at the research, when the CBT-E is well delivered by people who know how to deliver it, around half to two thirds of people who start, CBT-E experience significant improvement and though that sort of improvement is sustained, in the longer term, a year or so, later. So most people get better and it is one of the most well supported evidence-based treatments for eating disorders. However, having said that, that's still telling us that there are some people who don't get better, we have work to do. And we also know that eating disorders affects many different types of people. There is a stereotype that it's sort of young teenage girls, white, cisgender, there's this whole kind of stereotype. But of course they affect lots of people and so we probably do need to make sure that we do more work in making sure that we research how to deliver CBT-E in a way that benefits people, with the whole diversity of factors which exist in eating disorders. We might need to think about how best to adapt it and work with people who have eating disorders and other co-occurring conditions, and so on. But I guess the take home is that I guess, most people do get better but we still want to get more people better.
Rachel: If you can get the right therapy from the right people, there's a good chance you're going to improve and get well. In recent years, you've been very much focused on that kind of accessibility to treatment. You've been focused on digitalisation of CBT-E. Given those issues you've talked about, the challenges that people face in accessing therapy that sounds really important. So what are you doing and how is it going?
Rebecca: So the starting point here was that even though we have really good therapists delivered psychological treatments, only a small fraction of people receive them. And this is especially true for people with recurrent binge eating so because of the shame and sort of not being enough therapists. So what we've done is we've taken our therapist led CBT-E, and we've taken a printed program led version, and what I mean by this is a, sort of like a self-help book, Overcoming Binge Eating. It's the printed program led version of CBT-E, so you have a program delivering the therapy or the advice rather than a therapist but it's using the same kind of principles and ingredients from therapy. We've taken the printed program, we've taken our therapist led program and from that we've derived a digital app, a smartphone app and website-based program led treatment. So we've made some adaptations in terms of what we know about how people use digital treatments but we've used our tried and tested active ingredients to develop this treatment. We've involved people with lived experience, experts by experience. We've listened to them about what they found helpful, integrated their feedback and being through many cycles, iterative cycles, of development. So we do now have the treatment, it is available, but it's, even though it's on the app store, sadly you can't really do anything with it unless you are in the process of working with, for example, some NHS trusts that are using it now. But it's not available to everyone at the moment, but we are starting to run some pilots in the NHS and think about how to roll it out and implement it more widely.
Rachel: Fantastic. So addressing those questions of whether it works and in whose hands it works. And across the sort of face to face and digital packages you've got right now, you've been teaching, supervising, applying that, developing it. I know that development of the digital space has been a labour of love for you. What are the most frequent issues that come up for therapists? Where do they get stuck? What kind of questions do they ask when using CBT-E?
Rebecca: Probably the biggest struggle that people have is with how to apply CBT-E flexibly, but within a framework. And I think that's where quite a lot of the time therapists get stuck because, and this is partly our responsibility as trainers and supervisors to try and convey the message that the treatment itself isn't a set of, kind of, if/then rules; if the patient does this, then you must do this, because then in reality everyone's different. So nobody does exactly how you might describe in a training manual. So what we need to try and do is to do what I found very helpful in my training and supervision that I had from Chris and Zafra, which was think more about what are the principles underlying and guiding our decisions. So CBT-E is very much a formulation driven or diagram driven treatment. One principle is that you start with thinking really trying to understand something before you change it, trying to understand what's keeping it going, another principle is sort of doing a few things well, rather than many things badly, maybe staying focused as a therapist which people often find hard because typically, and this is only natural, when things get tough you tend to sort of drift away. You think, oh well, I don't know what to do about this within this framework, which perhaps you've internalised as a set of if/then rules. So you perhaps drift and bring in something else. I think that's probably the biggest area that we need to work on in terms of training and supervising, which is to help people to build in flexibility from the position of understanding a framework, but then still staying within an evidence-based approach rather than perhaps making up something new or trying to combine elements from a very different therapeutic model.
Rachel: So we often talk in CBT, don't we about sort of fidelity with flexibility and of course when you're learning something new, it's terribly reassuring to have a series of tick boxes that you can tick off and procedures you can do. But if we're being truly formulation led and person centred in a way, thinking about the individual that's in front of us whilst adhering to that model and the evidence-based principles, we're not just ticking off boxes and doing the next thing or grabbing something that we think might work.
And this area is one that can be personally taxing to work in. It can be challenging. I had the very great good fortune many years ago to work briefly with some of your more longstanding colleagues, Roz Shafron and Chris Fairburn. And I remember touching base with Roz after conducting a series of interviews with young women with anorexia nervosa for a study she was running. And being wonderfully empathic and thoughtful as she was, conscious of the impact it might have had on me sitting for the first time with a series of women who so undervalued their well-being that they were pursuing this path of self-starvation really. And so she asked me something along the lines of, do you feel ten years older? And in those moments, I think I did, actually. There was something so very sad and shocking about these amazing young women with so much potential and so many gifts and talents with so much to offer the world, working so hard just to take up less space in that world. And something else I noticed working with colleagues is how hard it is for those working in the field not to become very focused on food and weight and shape themselves in one way or another. I wonder what your reflections might be on looking after ourselves as therapists in this area and how we might be challenged by the work and how we might have to reflect on, modify our own assumptions and rules or how we look after ourselves generally.
Rebecca: I quite like that expression of putting your own oxygen mask on first. And I think as therapists, we do have a responsibility to look after ourselves, not just because we've got a responsibility to ourselves, we are people too and we need to look after ourselves. But also if we aren't looking after ourselves then we risk not being the best therapist that we can be to help other people. So I think when I entered the field, I was mindful of the fact that, and this would be true for other areas as well, but you become vulnerable potentially to being kind of sensitised by or sensitive to the sort of topics of conversation that dominate your time with patients. And of course, one of the qualities of being a therapist is being empathetic and entering people's worlds. And sometimes you enter them so deeply that you kind of, you don't have that benefit of that distant kind of kind of perspective, which you really need in order to be helpful so it can be easy to get drawn in and then become almost enabling of the eating disorder because you're so on the patients side that they take you into their kind of world. I think as therapists, what we need to do is be reflective as we go on, that we’re not taking those perspectives and integrating them into our views. And, in supervision, I do raise this issue and I think it's important if people feel able to be able to talk to their supervisors about this, and to be reflective, so that we can be the best therapist that we can be, because I think people with eating disorders are understandably able to listen so carefully to what we say as therapists, they listen so carefully to anything we reveal in terms of our views of people's bodies, of how people eat and unless we are really unambiguous about, for example, valuing people of all shapes and sizes. And unless we're unambiguous about valuing flexibility and eating, then people will hear even the tiniest little bit of drift that you might take as a therapist towards internalising weight stigma or any of those sorts of things. I think we have a responsibility, not just in terms of looking after ourselves, but have a responsibility to our patients to be mindful about that.
Rachel: And I guess the flip side of those challenges that we face and things that could be taxing are also the tremendous privilege that we have, having these windows into lives of people who are extraordinarily resilient, folk who really are surviving on so little, or cycling around these really self-defeating cycles of self-loathing. I'm wondering what you've learned from the people you've worked with, and how this works maybe made a personal difference in your life or the focus of your work.
Rebecca: Yes, and I think that's absolutely true what you've said. I suppose when you start off training and entering this world, you can read in the literature about how effective treatments are and so on. But I think unless you actually see it for yourself it's quite hard to really believe the research. I mean, we know it's sort of there, but I think you need to see people being able to make changes, to really believe it to be true, which you then need to go on and be able to kind of inspire and encourage other people with their recovery. So I suppose that's one of the things that I think I have learned which is that, for many people, change is possible and I think that's something as a therapist that you need to see to believe. So I think that has been important to me. And I think the other thing that you see is you see, exactly as you said, amazing people with such skills and resources that perhaps they are very much putting into kind of perhaps the areas of weight, shape, and eating but what you're trying to do in therapy is encourage them to take a massive risk away from what feels safe and what feels, it might even feel the right thing to be doing, and you're trying to get them to step into a very unknown, scary world, trusting that things could be different, and I think maybe what I've learned from people is that taking those risks can be really worthwhile. And I don't think I'm a big risk taker myself, so I'd probably find that really quite hard to do so I'm quite impressed when people do that. I'm quite impressed by how many changes they make in their lives. But I don't think that's easy. It's quite inspiring for me.
Rachel: And we've spoken about how the therapy is doing really well, half to two thirds of people seeing improvement getting better. The digitalisation, hopefully going to take it further in terms of access. What are the next big challenges, do you think? Can the therapy outcomes be impro
