Clinicians' concerns about delivering cognitive-behavioural therapy for eating disorders

Clinical Experiences Using Cognitive-Behavioral Therapy for Eating Disorders

Data suggests that despite the availability of evidence-based psychological treatments for eating disorders (EDs), techniques from these therapies may be less frequently used within real-life clinical practice. The aim of this study was to provide the opportunity for clinicians to give feedback on their experiences treating EDs using cognitive-behavioral therapy (CBT) through reporting on use of CBT techniques and barriers to treatment implementation in naturalistic settings. Clinicians (N = 126) who self-identified as using CBT for EDs reported demographic information, frequency/usefulness of empirically supported treatment techniques, problems/limitations of CBT, and barriers faced while implementing CBT. The most frequently used technique reported by clinicians was psychoeducation, and the least frequently used technique was use of surveys to address mind reading. Patients' unwillingness to follow a meal plan/nutritional guide was rated as the most impactful barrier, alongside ED severity. Of the problems/limitations of CBT, too little guidance on treating co-occurring symptoms was rated as the most impactful. This study provided a mechanism for clinicians to share their experiences using CBT for EDs in real-world settings. Overall, results regarding frequency of use and usefulness of techniques indicate a high level of endorsement. Moreover, the most frequently endorsed barriers to/limitations of CBT related to lack of guidance on treating complex ED presentations. Future research should explore ways to treat cases that go beyond the prototypical ED case and explore ways to adapt CBT to meet the needs of naturalistic treatment settings.

Systematic Search and Scoping Review of Physicians' Intolerance of Uncertainty and Medical Decision-Making Uncertainties During the COVID-19 Pandemic: A Summary of the Literature and Directions for Future Research

Pandemic-related uncertainties and intolerance of uncertainty (IU) could negatively affect physicians' well-being and functioning, being associated with experiences of distress and problematic decision-making processes. To summarize the available quantitative and qualitative evidence of physicians' IU and decisional uncertainty during COVID-19 and problems associated with it, a systematic search was conducted to identify all relevant articles describing physician uncertainty with regard to medical decision making and well-being in COVID-19 pandemic conditions. Medical, psychological, and preprint databases were searched. Ten articles met all eligibility criteria, with eight describing quantitative and two describing qualitative research outcomes, assessed primarily in European regions and via online surveys. Associations between IU and symptoms of poor mental health and mental health risk factors were widespread, but inconsistencies emerged. Qualitative studies emphasized decisional uncertainty as a stressor for physicians, and quantitative studies suggest it may have fostered more unproven treatment choices. While the prevalence and impact of physician uncertainty under COVID-19 conditions requires further investigation, sighting available literature indicates that IU coincided with experiences of poor mental health and, at least towards the beginning of the pandemic, with willingness to endorse unproven treatments. Efforts to reduce uncertainty-related problems for physicians seem warranted, for example, through normalizing experiences of uncertainty or reducing avoidable uncertainty through maintaining open and timely communication channels.

Therapist Anxious Distress and Avoidance of Implementing Time-Out

Therapist anxious distress when delivering child mental health treatment has been understudied as a factor that contributes to the underuse of some evidence-based interventions (EBIs), such as time-out for children with disruptive behaviors. This study investigated therapist anxious avoidance of time-out using a three-part, vignette-based survey design. Therapists (n = 198) read a vignette of an in-session time-out and reported on their personal anxious distress and likelihood of discontinuing the implementation of time-out. Therapists also provided open-ended descriptions of challenges to delivering time-out. Therapists reported moderate anxious distress at time points 1 and 2 and lower anxious distress at time 3 when the time-out had resolved. Most therapists endorsed some avoidance of time-out. Binomial logistic regression analyses indicated that increased anxious distress corresponded with an increased probability of avoiding time-out delivery in the future. Qualitative reports expanded on challenges to implementing time-out. Findings suggest the importance of addressing therapist anxious distress when implementing children's mental health treatments.

Reflective Skills, Empathy, Wellbeing, and Resilience in Cognitive-Behavior Therapy Trainees Participating in Mindfulness-Based Self-Practice/Self-Reflection

Self-Practice/Self-Reflection (SP/SR) is an aspect of therapist training and professional development aimed at enhancing therapy skills, empathy, wellbeing, and resilience in the ultimate furtherance of client outcomes. For many decades, intensive SP/SR has been a required part of therapist training in many countries but relatively little is known about the effect of SP/SR. Studies have found cognitive-behavior therapy (CBT) therapists trained under a Beckian CBT paradigm benefitted from more time limited Beckian SP/SR. Mindfulness-based CBT is a more recent third-wave CBT paradigm with psychological process aims similar to those of SP/SR. While training in mindfulness-based CBT often has prominent SP/SR aspects, and mindfulness practice has been shown to benefit health care providers personally and professionally, to date no evaluations have been reported specifically of effects of participation of CBT trainees in stand-alone mindfulness-based SP/SR that meets regulatory requirements for more intensive SP/SR. A study on SP/SR training meeting German requirements is reported here. Post-graduate CBT trainees (N = 95) were assigned to delayed or immediate SP/SR with those in the delayed SP/SR condition crossing-over into SP/SR training after two baseline evaluations on a variety of reflective skill, wellbeing, and resilience measures spaced six to 9 months apart before participating in 120-150 hours of stand-alone mindfulness-based SP/SR followed by a third reevaluation on all study measures. Participants assigned to the immediate SP/SR condition underwent identical SP/SR training with pre/post assessments. Results indicate participation in intensive stand-alone mindfulness-based SP/SR resulted in favorable changes in measures operationalizing all variables. Findings are discussed in terms of their implications for training and professional development of CBT therapists.

Impact of patient characteristics on clinicians' decisions to involve dietitians in eating disorder treatment

BACKGROUND & AIMS

Dietetic involvement in eating disorder (ED) treatment is often initiated by other members of a patient's treating team. This study aimed to examine the impact of patient characteristics on clinicians' decisions to involve a dietitian in a patient's ED treatment, as well as the influence of clinician characteristics on their decision-making.

METHODS

ED clinicians were recruited to complete an online survey, which used case vignettes to assess their likelihood of referring patients to a dietitian or consulting with a dietitian for guidance. Questions were also included measuring clinician anxiety, beliefs about the therapy they deliver, beliefs about dietitians and views on evidence-based practice, to determine if these were related to their responses to case vignettes.

RESULTS

Fifty-seven clinicians completed the survey, with the largest group being clinical psychologists (n=22, 39%). ED diagnosis, weight status, medical co-morbidities and progress in treatment were all shown to be influential on whether clinicians involved dietitians in ED treatment. Clinician characteristics and their beliefs about dietitians were generally not correlated with the likelihood of seeking dietetic input.

CONCLUSIONS

This study indicates that clinicians' decisions to involve dietitians in ED treatment are systematic rather than random decisions influenced by individual clinician characteristics. Clinicians require further education on the potential for malnutrition regardless of patients'ED diagnosis or weight status, and the dietitian's role in addressing this.

Classification of subtypes of patients with eating disorders by correspondence analysis

BACKGROUND

Grouping eating disorders (ED) patients into subtypes could help improve the establishment of more effective diagnostic and treatment strategies.

AIM

To identify clinically meaningful subgroups among subjects with ED using multiple correspondence analysis (MCA).

METHODS

A prospective cohort study was conducted of all outpatients diagnosed for an ED at an Eating Disorders Outpatient Clinic to characterize groups of patients with ED into subtypes according to sociodemographic and psychosocial impairment data, and to validate the results using several illustrative variables. In all, 176 (72.13%) patients completed five questionnaires (clinical impairment assessment, eating attitudes test-12, ED-short form health-related quality of life, metacognitions questionnaire, Penn State Worry Questionnaire) and sociodemographic data. ED patient groups were defined using MCA and cluster analysis. Results were validated using key outcomes of subtypes of ED.

RESULTS

Four ED subgroups were identified based on the sociodemographic and psychosocial impairment data.

CONCLUSION

ED patients were differentiated into well-defined outcome groups according to specific clusters of compensating behaviours.

Early response to psychological treatment for eating disorders: A systematic review and meta-analysis

Early response is a well-established predictor of positive outcomes at the end of psychological treatments for common mental disorders. There is some prior evidence that this conclusion also applies to eating disorders, including three meta-analyses, but no moderators of that relationship have been identified. However, a number of further papers have been published since, which might influence the size of the effect of early response or the potential role of moderating factors. This pre-registered systematic review presents a comprehensive examination of this literature. Three databases were searched (Scopus, PsycInfo, PubMed). In total, 33 eligible studies were included in a narrative synthesis, and 25 studies were included in random-effects meta-analysis. The majority (91%) of studies were rated as having low or moderate risk of bias. Approximately half of patients across clinical samples showed early response to psychological therapy, which was most often defined as reliable symptomatic improvement during the first four sessions. A significant and moderate association was found between early response and post-treatment outcomes (r = 0.41 [95% CI: 0.32-0.481], p < .0001). Significant evidence of heterogeneity (Q[28] = 136.42, p < .0001; I² = 80.2%) was evident. The review was limited by the exclusion of grey literature and only 76% of studies provided sufficient statistical information for meta-analytic synthesis, although we found no significant evidence of publication bias, χ²(1) = 0.001, p = .97. Overall, evidence accumulated over twenty years establishes early response as the most robust predictor of treatment outcomes in the field of eating disorders. However, only half of patients show early change in this way. Further research is needed to determine whether there are patient or clinician characteristics that predict early response to psychological treatment for eating disorders.

Registered report: Initial development and validation of the eating disorders safety behavior scale

Anxiety and eating disorders (EDs) often co-occur, prompting calls to explore anxiety-related maintenance processes in ED samples. Safety behaviors, which function to prevent a feared outcome from occurring or to reduce anxiety associated with a feared stimulus, are observed across anxiety disorders and, along with overt avoidance behaviors, are an important target in treatment. Data suggest that individuals with EDs also engage in safety behaviors. However, no existing assessments provide a comprehensive measure of eating-disorder-specific overt avoidance and safety behaviors. The goal of this Stage 1 Registered Report is to develop a comprehensive self-report measure of ED-specific safety behaviors. In Study 1, we will recruit 50 women with EDs to complete the scale and provide feedback on the response scale. Feedback from these participants will be used to refine the measure. In Study 2, we will evaluate the psychometric properties of the measure in a large sample of women with EDs (n dependent on the size of measurement) and a community sample without current or a history of ED symptoms. We will explore the measure factor structure, known-groups validity by comparing scores from women with EDs to healthy controls, internal consistency, and convergent and divergent validity with other psychological instruments.

Are we on the same page? A comparison of patients' and clinicians' opinions about the importance of CBT techniques

Clinicians often omit or underuse several techniques while delivering therapy. These omissions can be due to unconscious factors (e.g., clinician's anxiety), or due to clinicians' deliberate decisions (e.g., modifying therapy believing that such modifications are on the patients' best interests). However, little is known about whether patients consider these modifications necessary. The main aim of this study was to explore the opinions about the important aspects of CBT according to both patients' and clinicians' perspectives. It also aimed to determine whether clinicians' anxiety influenced such preferences. To achieve these aims, two groups of participants were approached-CBT clinicians (n = 83) and CBT patients (n = 167). An online survey with a list of techniques commonly used in CBT was developed for each group, who indicated the importance they attributed to the techniques. Additionally, clinicians completed an anxiety measure. Results indicated that clinicians valued all "change-oriented" techniques and several "interpersonal engagement" techniques more than the patients. The only technique preferred by patients was "relaxation". Higher levels of clinician anxiety were associated with a lower preference for "behavioural experiments" and "exposure". In conclusion, clinicians are encouraged to plan therapy in collaboration with the patient, as well as to discuss the rationale for the implemented techniques.

Reevaluating Cue Exposure and Response Prevention in a Pilot Study: An Updated Treatment for Binge Eating Disorder

Approximately half of individuals with binge eating disorder (BED) fail to improve when treated with cognitive behavioral therapy; thus, better treatments are needed. Cue exposure and response prevention (CERP) may be one option, but its full potential for reducing binge eating remains unknown because prior applications for binge eating have not utilized the broad range of strategies believed to optimize exposure therapy. The current single-subject AB design investigated the acceptability and effectiveness of a comprehensive CERP treatment among 8 women who met DSM-5 criteria for binge eating disorder. Changes in the number of binges were measured from baseline to the end of treatment, and desire to eat, salivation, and idiographic expectancies of aversive outcomes to food-cue exposure (idiographic CS-US expectancies), including expectancies about ability to tolerate distress when exposed to food cues were measured across the course of treatment. Statistical analysis revealed a significant reduction in the number of binges from baseline to the end of treatment. Across the course of treatment, desire to eat and idiographic CS-US expectancies reduced, and distress tolerance expectancies increased. No participants dropped out and all reported being maximally satisfied with the treatment. Based on these findings, future randomized-control trials with larger samples should examine the efficacy of CERP and mechanisms underlying change with the aim of establishing a more effective treatment for binge eating disorder.

Conceptualizing eating disorder psychopathology using an anxiety disorders framework: Evidence and implications for exposure-based clinical research

Eating disorders (EDs) and anxiety disorders (ADs) evidence shared risk and significant comorbidity. Recent advances in understanding of anxiety-based disorders may have direct application to research and treatment efforts for EDs. The current review presents an up-to-date, behavioral conceptualization of the overlap between anxiety-based disorders and EDs. We identify ways in which anxiety presents in EDs, consider differences between EDs and ADs relevant to treatment adaptions, discuss how exposure-based strategies may be adapted for use in ED treatment, and outline directions for future mechanistic, translational, and clinical ED research from this perspective. Important research directions include: simultaneous examination of the extent to which EDs are characterized by aberrant avoidance-, reward-, and/or habit-based neurobiological and behavioral processes; improvement in understanding of how nutritional status interacts with neurobiological characteristics of EDs; incorporation of a growing knowledge of biobehavioral signatures in ED treatment planning; development of more comprehensive exposure-based treatment approaches for EDs; testing whether certain exposure interventions for AD are appropriate for EDs; and improvement in clinician self-efficacy and ability to use exposure therapy for EDs.

The impact of teaching clinicians about implementing exposure therapy with patients with eating disorders: A nonrandomized controlled study

OBJECTIVE

Exposure therapy is a central part of cognitive behavior therapy (CBT) for eating disorders, but is underused in routine clinical practice, at least partly because clinicians often hold very negative views about this technique. Although uncontrolled cohort studies suggest that teaching clinicians to use exposure improves their attitudes, there is a need for more robust empirical designs. This study uses a nonrandomized controlled design to test whether teaching on exposure improves clinicians' attitudes to its use, and whether clinician characteristics influence such change.

METHOD

Forty-seven clinicians undertook 90 min of teaching on exposure therapy within CBT, while 42 other clinicians undertook 90 min of teaching on CBT for eating disorders. Each completed the Therapist Beliefs about Exposure Scale at the outset and end of the intervention, and the Intolerance of Uncertainty Scale at the outset.

RESULTS

Both groups showed improved attitudes to exposure therapy following the teaching, but the change was substantially larger in the Exposure teaching group (d = 0.85) than in the Comparison group (d = .30). Preteaching characteristics did not have any substantial influence on this change in attitudes to exposure.

DISCUSSION

These findings strengthen the conclusion that a simple teaching intervention can improve clinician attitudes to the exposure therapy element of CBT (and other therapies). However, the nonrandomized design and self-selected sample limit the interpretability of the findings. Further research is suggested to develop these findings and determine their link to clinician behavior in therapy.

[Exploring Mechanisms of Action in Exposure-Based Cognitive Behavioral Therapy for Eating Disorders: The Role of Eating-Related Fears and Body-Related Safety Behaviors]

Evidence-based cognitive behavioral therapy for eating disorders includes a component of exposure therapy, which involves patients confronting feared eating and body-related stimuli while preventing safety behaviors. With recent research demonstrating that eating-related fears and safety behaviors are central to eating disorder pathology, there is increased emphasis on improving the efficacy of exposure therapy in eating disorders. Doing so will require a better understanding of important mechanisms of action in this treatment. The present study explored how changes during treatment in eating-related fears and avoidance as well as body-related safety behaviors influence overall treatment outcomes. Individuals with eating disorders (N = 71) receiving exposure-based treatment completed measures of global eating disorder severity at admission and discharge. Hypothesized mechanisms of action were also assessed at admission and discharge as well as at a 2-week time point after beginning treatment. Path modeling analyses showed that decreased eating-related cognitions (feared concerns about eating) and emotions (anxiety about eating) at the 2-week time point were prospectively predictive of lowered global eating disorder symptom severity at discharge. Additionally, reduced body checking and avoidance behaviors after 2 weeks of treatment were also associated with lower eating disorder severity at discharge. These findings highlight the importance of exposure-based therapy in eating disorders and the need to uniquely address eating-related fears and safety behaviors.

Clinician and patient characteristics and cognitions that influence weighing practice in cognitive-behavioral therapy for eating disorders

OBJECTIVE

Clinicians commonly fail to weigh patients appropriately in cognitive-behavioral therapy for eating disorders (CBT-ED), despite guidelines stressing the need to do so. This study considered the possible patient- and clinician-based reasons why this element of treatment is omitted.

METHOD

Seventy-four CBT-ED clinicians were presented with vignettes that varied in patient diagnosis and distress levels, to determine whether those characteristics influenced different clinician weighing practices. Clinicians' own attitudes to weighing and their anxiety levels were also assessed to determine whether they were related to weighing intentions.

RESULTS

Clinicians were more likely to weigh patients with anorexia nervosa than patients with bulimia nervosa, probably due to focusing on physical risk. However, they were less likely to weigh patients who were distressed at the prospect, despite that course of action being particularly clinically indicated. Clinicians were more likely to weigh patients if they had positive beliefs about the value of doing so, and if they were not prone to making unsupported exceptions in delivering this technique.

DISCUSSION

This study provides evidence that clinicians use weighing differently according to the patient's presentation and their own beliefs, rather than working within guidelines. Education, training, and supervision are suggested to help clinicians address this failure to weigh patients in the most therapeutic way.

Body Image in the Context of Eating Disorders

Body dissatisfaction is a risk factor for development of eating disorders and represents a core psychopathologic feature of eating disorders. Prevention and treatment interventions address established risk and maintaining factors for body dissatisfaction: appearance pressures, internalization of appearance ideals, upward appearance comparison, avoidance and checking, and body disparagement. It is essential to address body dissatisfaction within eating disorders treatment to improve outcomes and reduce risk of relapse. Future directions in research and treatment aim to reach populations increasingly recognized as in need, including children, men, and individuals at higher weights, with the ultimate goal of reducing the significant distress associated with body dissatisfaction.

Tolerance of uncertainty: A systematic review of health and healthcare-related outcomes

BACKGROUND

Uncertainty tolerance (UT) is thought to be a characteristic of individuals that influences various outcomes related to health, healthcare, and healthcare education. We undertook a systematic literature review to evaluate the state of the evidence on UT and its relationship to these outcomes.

METHODS

We conducted electronic and bibliographic searches to identify relevant studies examining associations between UT and health, healthcare, or healthcare education outcomes. We used standardized tools to assess methodological quality and analyzed the major findings of existing studies, which we organized and classified by theme.

RESULTS

Searches yielded 542 potentially relevant articles, of which 67 met inclusion criteria. Existing studies were heterogeneous in focus, setting, and measurement approach, were largely cross-sectional in design, and overall methodological quality was low. UT was associated with various trainee-centered, provider-centered, and patient-centered outcomes which were cognitive, emotional, and behavioral in nature. UT was most consistently associated with emotional well-being.

CONCLUSIONS

Uncertainty tolerance is associated with several important trainee-, provider-, and patient-centered outcomes in healthcare and healthcare education. However, low methodological quality, study design limitations, and heterogeneity in the measurement of UT limit strong inferences about its effects, and addressing these problems is a critical need for future research.

Supervisor practice when guiding therapists working with depression: the impact of supervisor and patient characteristics

Currently recommended psychotherapies for depression are not always delivered in a consistent manner. There is an assumption that the use of clinical supervision will ensure reliable treatment and patient recovery. However, there is limited research supporting this assumption. This study explored the role of supervision in the treatment of depression. In particular, it examined how supervisors’ own characteristics and those of patients can influence the focus of supervision sessions. Clinical supervisors who worked with cognitive behavioural therapy (CBT) therapists treating depression cases were asked to indicate their supervision focus for three different patient vignettes. These vignettes varied in clinical complexity. Participants’ intolerance to uncertainty and their self-esteem were also assessed. Supervisors tended to focus their supervisees on the use of evidence-based therapeutic techniques for both straightforward and complex cases. However, their approach was less evidence-based for diffuse cases. Three supervisory types emerged: an ‘Alliance- and Technique-Focused’ group, a ‘Case Management-Focused’ group, and an ‘Unfocused’ group. Personal characteristics of the supervisors varied across the groups. The content of supervision sessions is influenced by factors from outside the therapy process. These factors might cause supervisors to avoid focusing on evidence-based aspects of therapy, thus feeding therapist drift. Suggestions are made for new supervision protocols that consider the supervisor's personal characteristics.

The role of sociocultural perspectives in eating disorder treatment: A study of health professionals

Eating disorders are now often approached as biopsychosocial problems, because they are widely recognised as multifactorial in origin. However, it has been suggested that there is a substantial and unwarranted imbalance within this biopsychosocial framework, with the 'social' aspects of the equation relegated to secondary or facilitating factors within treatment contexts. Drawing on data from 12 qualitative interviews with health professionals in a UK region, this article examines the extent to which sociocultural perspectives on eating disorders are valued and explored in eating disorder treatment, with a particular focus on the relationship between eating disorders and gender. As girls/women are widely acknowledged to be disproportionately affected by eating problems, the article draws on feminist perspectives on eating disorders to explore whether the relationships between cultural constructions of femininity and experiences of body/eating distress are actively addressed within treatment. The study reveals high levels of inconsistency in this regard, as while some participants see such issues as central to treatment, others have 'never really considered' them before. In addition, the study examines the potential limitations of how such sociocultural issues are conceptualised and addressed, as well as why they might be marginalised in the current climate of evidence-based eating disorder treatment. The article then considers the implications of the findings for thinking about feminist perspectives on eating disorders - and the significance of gender in treatment - at the level of both research and practice.

Development and Validation of the Negative Attitudes towards CBT Scale

BACKGROUND

Clinicians commonly fail to use cognitive behavioural therapy (CBT) adequately, but the reasons for such omissions are not well understood.

AIMS

The objective of this study was to create and validate a measure to assess clinicians' attitudes towards CBT - the Negative Attitudes towards CBT Scale (NACS).

METHOD

The participants were 204 clinicians from various mental healthcare fields. Each completed the NACS, measures of anxiety and self-esteem, and a measure of therapists' use of CBT and non-CBT techniques and their confidence in using those techniques. Exploratory factor analysis was used to determine the factor structure of the NACS, and scale internal consistency was tested.

RESULTS

A single, 16-item scale emerged from the factor analysis of the NACS, and that scale had good internal consistency. Clinicians' negative attitudes and their anxiety had different patterns of association with the use of CBT and other therapeutic techniques.

CONCLUSIONS

The findings suggest that clinicians' attitudes and emotions each need to be considered when understanding why many clinicians fail to deliver the optimum version of evidence-based CBT. They also suggest that training effective CBT clinicians might depend on understanding and targeting such internal states.

Purging behaviors and therapeutic prognosis of women with eating disorders treated in a healthcare context

Background/Objective: The evidence on efficacy of cognitive-behavioral interventions in Eating Disorders (ED) still shows inconclusive results with respect to the role of purging behaviors, more so in uncontrolled situations. Evolution of ED patients with and without purging behavior was studied 30 months after start of a multicomponent treatment. Method: 162 women (87 purging, 75 non-purging) treated in outpatient or hospitals + outpatient care units in Spain participated. The evaluation instruments were: BSQ, EAT-40, EDI, STAI, BDI and BITE. Results: At the beginning of the treatment, participants with purging behavior showed higher bulimic symptomatology, more body dissatisfaction, drive for thinness, perfectionism and ineffectiveness, anxiety and depressive symptomatology. After thirty months, intervention produced improvement in ED characteristics, emotional alterations and personal development variables, in both groups, but less in patients with no purging behavior. The effect of intervention was stronger in purging patients and variables with larger effect size: body dissatisfaction, bulimic symptomatology and anxiety. Conclusions: Purging behaviors must be considered in the design of these treatments with a view to prognosis.

Bulimia Nervosa: A Comprehensive Analysis of Treatment, Policy, and Social Work Ethics

Bulimia nervosa is an often debilitating eating disorder with a biopsychosocial set of risk factors. Those presenting are at an increased mortality rate and often have physical health complications as well as harmful cognitions related to self-esteem and overall self-concept. This article examines treatment, policy, and social work ethics as they relate to bulimia nervosa. A comprehensive cognitive-behavioral approach including psychoeducation, self-monitoring, exposure therapy, interpersonal therapy, body image therapy, energy balance training, and relapse prevention is recommended as evidence-based practice for treating bulimia nervosa. Authors identify health care policy and analyze it as a common barrier to treatment access. They also review ethical principles of competency and social justice as they relate to social work practitioners working with those diagnosed with bulimia nervosa.

The three-legged stool of evidence-based practice in eating disorder treatment: research, clinical, and patient perspectives

BACKGROUND

Evidence-based practice in eating disorders incorporates three essential components: research evidence, clinical expertise, and patient values, preferences, and characteristics. Conceptualized as a 'three-legged stool' by Sackett et al. in 1996 (BMJ), all of these components of evidence-based practice are considered essential for providing optimal care in the treatment of eating disorders. However, the extent to which these individual aspects of evidence-based practice are valued among clinicians and researchers is variable, with each of these stool 'legs' being neglected at times. As a result, empirical support and patient preferences for treatment are not consistently considered in the selection and implementation of eating disorder treatment. In addition, clinicians may not have access to training to provide treatments supported by research and preferred by patients. Despite these challenges, integrating these three components of evidence-based practice is critical for the effective treatment of eating disorders.

DISCUSSION

Current research supports the use of several types of psychotherapies, including cognitive-behavioral, interpersonal, and family-based therapies, as well as certain types of medications for the treatment of eating disorders. However, limitations in current research, including sample heterogeneity, inconsistent efficacy, a paucity of data, the need for tailored approaches, and the use of staging models highlight the need for clinical expertise. Although preliminary data also support the importance of patient preferences, values, and perspectives for optimizing treatment, enhancing treatment outcome, and minimizing attrition among patients with eating disorders, the extent to which patient preference is consistently predictive of outcome is less clear and requires further investigation. All three components of evidence-based practice are integral for the optimal treatment of eating disorders. Integrating clinical expertise and patient perspective may also facilitate the dissemination of empirically-supported and emerging treatments as well as prevention programs. Further research is imperative to identify ways in which this three-legged approach to eating disorder treatment could be most effectively implemented.

Treatment Protocols for Eating Disorders: Clinicians' Attitudes, Concerns, Adherence and Difficulties Delivering Evidence-Based Psychological Interventions

There are several protocols in existence that guide clinicians in the implementation of effective, evidence-based psychological interventions for eating disorders. These have been made accessible in the form of treatment manuals. However, relatively few clinicians use those protocols, preferring to offer more eclectic or integrative approaches. Following a summary of the research that shows that these evidence-based approaches can be used successfully in routine clinical settings, this review considers why there is such poor uptake of these therapies in such settings. This review focuses on the role of service culture and on clinicians' own attitudes, beliefs and emotions. Possible means of enhancing uptake are considered, but these cannot be considered to be ideal solutions at present.

Facets of clinicians' anxiety and the delivery of cognitive behavioral therapy

Psychological therapists commonly fail to adhere to treatment protocols in everyday clinical practice. In part, this pattern of drift is attributable to anxious therapists being less likely to undertake some elements of evidence-based therapies - particularly the exposure-based elements. This study considers what facets of anxiety (cognitive, behavioral, physiological) are related to junior clinicians' reported use of cognitive-behavioral therapy techniques. Thirty-two clinicians (mean age = 28.9 years; mean length of CBT experience = 1.5 years; 23 female, nine male) who offered CBT were assessed for their cognitive, behavioral and physiological characteristics (Intolerance of Uncertainty scale; risk taking; skin conductance response and heart rate variability). While the three different facets of anxiety were relatively poorly associated with each other, as is usual in this literature, each facet was linked differently to the reported delivery of CBT techniques (P < .05). Overall, higher anxiety levels were associated with a poorer use of exposure methods or with a greater use of other behavioral or cognitive methods. Of the three facets of anxiety, only physiological reactivity showed an association with the clinicians' temporal characteristics, with more experienced therapists being more likely to have greater skin conductance responses to positive and negative outcomes. These findings suggest that clinicians who are more anxious are less likely to deliver the full evidence-based form of CBT and to focus instead on less challenging elements of the therapy. Potential ways of overcoming this limitation are discussed.

Therapist drift redux: Why well-meaning clinicians fail to deliver evidence-based therapy, and how to get back on track

Therapist drift occurs when clinicians fail to deliver the optimum evidence-based treatment despite having the necessary tools, and is an important factor in why those therapies are commonly less effective than they should be in routine clinical practice. The research into this phenomenon has increased substantially over the past five years. This review considers the growing evidence of therapist drift. The reasons that we fail to implement evidence-based psychotherapies are considered, including our personalities, knowledge, emotions, beliefs, behaviours and social milieus. Finally, ideas are offered regarding how therapist drift might be halted, including a cognitive-behavioural approach for therapists that addresses the cognitions, emotions and behaviours that drive and maintain our avoidance of evidence-based treatments.

Impact of education on clinicians' attitudes to exposure therapy for eating disorders

It is well established that clinicians use exposure therapy far less often than the evidence would suggest is justified. This shortfall has been explained as being at least partly a result of clinicians' beliefs and attitudes about exposure and their trait anxiety. Recent studies have shown that attitudes to exposure therapy for anxiety disorders can be improved through a simple educational approach. This study aimed to determine whether a similar educational approach can improve therapists' attitudes to exposure therapy for the eating disorders, and whether clinician's pre-intervention characteristics influenced the impact of the training. Thirty-four eating disorder clinicians (30 female, four male; mean age = 39.0 years; 85.3% Caucasian) attended a 90-min didactic teaching session on the subject of the use of exposure in treatment of eating disorders. Their attitudes to exposure therapy were measured before and after the workshop, in a within-subject design. The outcome was a substantial improvement in attitudes, with a strong effect size (Cohen's d = 1.68) that was comparable to the outcome of a similar intervention among clinicians working with anxiety disorders. The improvement was not related to clinicians' anxiety levels, but was greater among those whose attitudes were more negative at the outset of the teaching. While this finding needs to be tested for long-term maintenance and its relationship to change in clinical practice, it adds to the evidence that a simple educational intervention is sufficient to result in substantial improvement in clinicians' attitudes to exposure therapy.

Weighing patients within cognitive-behavioural therapy for eating disorders: How, when and why

While weight, beliefs about weight and weight changes are key issues in the pathology and treatment of eating disorders, there is substantial variation in whether and how psychological therapists weigh their patients. This review considers the reasons for that variability, highlighting the differences that exist in clinical protocols between therapies, as well as levels of reluctance on the part of some therapists and patients. It is noted that there have been substantial changes over time in the recommendations made within therapies, including cognitive-behavioural therapy (CBT). The review then makes the case for all CBT therapists needing to weigh their patients in session and for the patient to be aware of their weight, in order to give the best chance of cognitive, emotional and behavioural progress. Specific guidance is given as to how to weigh, stressing the importance of preparation of the patient and presentation, timing and execution of the task. Consideration is given to reasons that clinicians commonly report for not weighing patients routinely, and counter-arguments and solutions are presented. Finally, there is consideration of procedures to follow with some special groups of patients.

Cognitive-behavioural therapy for outpatients with eating disorders: effectiveness for a transdiagnostic group in a routine clinical setting

Whilst there is a growing evidence to support the impact of cognitive-behavioural therapy (CBT) in the treatment of adults with eating disorders, much of this evidence comes from tightly controlled efficacy trials. This study aimed to add to the evidence regarding the effectiveness of CBT when delivered in a routine clinical setting. The participants were 203 adults presenting with a range of eating disorder diagnoses, who were offered CBT in an out-patient community eating disorders service in the UK. Patients completed measures of eating disorder pathology at the start of treatment, following the sixth session, and at the end of treatment. Symptoms of anxiety, depression, and psychosocial functioning were measured pre- and post-treatment. Approximately 55% of patients completed treatment, and there were no factors that predicted attrition. There were significant improvements in eating disorder psychopathology, anxiety, depression and general functioning, with particular changes in eating attitudes in the early part of therapy. Effect sizes were medium to large for both completer and intention to treat analyses. These findings confirm that evidence-based forms of CBT can be delivered with strong outcomes in routine clinical settings. Clinicians should be encouraged to deliver evidence-based treatments when working in these settings.

Disseminating evidence-based psychological treatments for eating disorders

The research-practice gap is of concern in the treatment of eating disorders. Despite the existence of empirically supported treatments, few receive them. The barriers to wider dissemination and implementation of evidence-based treatment include clinician attitudes towards such treatments and the lack of sufficient numbers of suitably trained therapists to provide treatment. In this review we discuss these barriers in the context of the wider issue of the dissemination and implementation of psychological treatments and review the research with regard to the treatment of eating disorders. Particular emphasis is placed on examining recent efforts to expand the availability and reach of treatments by making treatment delivery and training more scalable. We highlight promising developments and areas where further research is needed.

BodyWise: evaluating a pilot body image group for patients with anorexia nervosa

Body image disturbance can be enduring and distressing to individuals with eating disorders and effective treatments remain limited. This pilot study evaluated a group-based treatment-BodyWise-developed for use in full and partial hospitalization with patients with anorexia nervosa at low weight. A partial crossover waitlist design was used. BodyWise (N = 50) versus treatment as usual (N = 40) were compared on standardized measures of body image disturbance. Results demonstrated significant improvement in the group compared to treatment as usual for the primary outcome measure (Eating Disorder Examination-Questionnaire Shape Concern subscale) and other manifestations of body image disturbance including body checking and body image quality of life. BodyWise appeared acceptable to participants, and was easy to deliver within the pragmatics of a busy eating disorder service. There is potential for its wider dissemination as a precursor to more active body image interventions.
