Edney LC, Pellizzer ML. Adaptive design trials in eating disorder research: A scoping review. Int J Eat Disord 2024; 57:1278-1290. [PMID: 38619362 DOI: 10.1002/eat.24198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 03/01/2024] [Accepted: 03/01/2024] [Indexed: 04/16/2024]
Abstract
OBJECTIVE This scoping review sought to map the breadth of literature on the use of adaptive design trials in eating disorder research. METHOD A systematic literature search was conducted in Medline, Scopus, PsycInfo, Emcare, Econlit, CINAHL and ProQuest Dissertations and Theses. Articles were included if they reported on an intervention targeting any type of eating disorder (including anorexia nervosa, bulimia nervosa, binge-eating disorder, and other specified feeding or eating disorders), and employed the use of an adaptive design trial to evaluate the intervention. Two independent reviewers screened citations for inclusion, and data abstraction was performed by one reviewer and verified by a second. RESULTS We identified five adaptive design trials targeting anorexia nervosa, bulimia nervosa and binge-eating disorder conducted in the USA and Australia. All employed adaptive treatment arm switching based on early response to treatment and identified a priori stopping rules. None of the studies included value of information analysis to guide adaptive design decisions and none included lived experience perspectives. DISCUSSION The limited use of adaptive designs in eating disorder trials represents a missed opportunity to improve enrolment targets, attrition rates, treatment outcomes and trial efficiency. We outline the range of adaptive methodologies, how they could be applied to eating disorder research, and the specific operational and statistical considerations relevant to adaptive design trials. PUBLIC SIGNIFICANCE Adaptive design trials are increasingly employed as flexible, efficient alternatives to fixed trial designs, but they are not often used in eating disorder research. This first scoping review identified five adaptive design trials targeting anorexia nervosa, bulimia nervosa and binge-eating disorder that employed treatment arm switching adaptive methodology. We make recommendations on the use of adaptive design trials for future eating disorder trials.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 20:ijerph20010119. [PMID: 36612445 PMCID: PMC9819826 DOI: 10.3390/ijerph20010119] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 12/13/2022] [Accepted: 12/14/2022] [Indexed: 05/30/2023]
Abstract
Bulimia nervosa is an eating disorder characterised by marked impairment to one's physical health and social functioning, as well as high rates of chronicity and comorbidity. This literature review aims to summarise existing academic research related to the symptom profile of BN, the costs and burden imposed by the illness, barriers to the receipt of care, and the evidence base for available psychological treatments. As a consequence of well-documented difficulties in accessing evidence-based treatments for eating disorders, efforts have been made towards developing innovative, diverse channels to deliver treatment, with several of these attempting to harness the potential of digital platforms. In response to the increasing number of trials investigating the utility of online treatments, this paper provides a critical review of previous attempts to examine digital interventions in the treatment of eating disorders. The results of a focused literature review are presented, including a detailed synthesis of a knowledgeable selection of high-quality articles with the aim of providing an update on the current state of research in the field. The results of the review highlight the potential for online self-help treatments to produce moderately sized reductions in core behavioural and cognitive symptoms of eating disorders. However, concern is raised regarding the methodological limitations of previous research in the field, as well as the high rates of dropout and poor adherence reported across most studies. The review suggests directions for future research, including the need to replicate previous findings using rigorous study design and methodology, as well as further investigation regarding the utility of clinician support and interactive digital features as potential mechanisms for offsetting low rates of engagement with online treatments.

Int J Eat Disord 2021; 54:1989-1997. [PMID: 34676907 DOI: 10.1002/eat.23629] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 10/10/2021] [Accepted: 10/11/2021] [Indexed: 01/20/2023]
Abstract
OBJECTIVE Stepped-care models of treatment are underexplored in eating disorders. To enhance treatment outcomes, and informed by literature about adaptations to family-based treatment (FBT), we developed an FBT-based stepped-care model for adolescents with anorexia nervosa (AN) that was consistent with family preference (i.e., tailored) and responsive to adolescent needs (i.e., intensity). The aim of this study was to evaluate the effectiveness of this model in terms of remission at end-of-treatment. METHOD Adolescents (N = 82), aged 12-18 years (M = 15.1, SD = 1.8) and meeting Diagnostic and Statistical Manual of Mental Disorders 5th Edition criteria for AN, were assessed at baseline, Weeks 24 and 48. FBT was tailored to family preference and clinical need, with 16-18 sessions by Week 24. This was followed by three FBT booster sessions or an extension of FBT plus booster sessions (Week 48). The primary outcome was defined as weight > 95% of %median body mass index plus within 1 SD of the Eating Disorder Examination (EDE) global score community norms. RESULTS Remission rates were 45.1% and 52.4% at Weeks 24 and 48, respectively. Commensurable improvements were evident across secondary outcomes (e.g., EDE subscale scores). As a reference point, remission rates compared positively with results from a recent randomized clinical trial from the same center and at the same time points (Week 24:45.1% vs. 32.1% and Week 48:52.4% vs. 30.2%). Controlling for propensity score, no statistically significant differences were observed. DISCUSSION This stepped-care model, designed to be responsive to the individual needs of adolescents and their families, achieved encouraging rates of remission. This study provides an important signal that supports future clinical trials of stepped-care models for adolescents with AN.

Can early change in eating disorder psychopathology predict outcome in guided self-help for binge eating? Eat Weight Disord 2021; 26:2143-2152. [PMID: 33145729 PMCID: PMC8437919 DOI: 10.1007/s40519-020-01059-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 10/16/2020] [Indexed: 11/02/2022] Open
Abstract
PURPOSE This study tests the value of a measure of eating disorder (ED) psychopathology in predicting outcome following guided self-help in a non-underweight sample with regular binge eating. It examines whether early reductions in ED psychopathology are associated with remission status at post-treatment. METHODS Seventy-two adults with bulimia nervosa, binge-eating disorder, or an atypical form of these illnesses received up to ten sessions of cognitive behaviour therapy-based guided self-help. Using a session-by-session measure of eating pathology and associated reliable change indices, response was analysed using receiver operating characteristic analysis to predict outcomes at post-treatment. RESULTS In this routine care setting, nearly one-quarter of the sample achieved remission following GSH, approximately two-thirds of whom showed early change in ED psychopathology. Early change prior to session 6 was accurate in predicting later remission. Individuals showing early change did not differ from others on baseline characteristics or rates of attrition. CONCLUSION Data suggest that a majority of those who respond to treatment will do so before the second half of treatment, information that could be used to ensure that evidence-based treatments are used as effectively as possible. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE This study compared the effectiveness of two approaches to imagery rescripting (body versus general) among young women with an elevated risk of developing an eating disorder. METHOD University students (N = 130 females) were randomly assigned to one of the four conditions: body or general imagery rescripting, psychoeducation, control. After initial brief laboratory training delivered online, participants in the imagery rescripting conditions were asked to practice imagery rescripting for 5 min each day for a week. Primary (global eating psychopathology, eating disorder behaviors, and body image acceptance) and secondary outcomes (self-compassion, fear of self-compassion, and dysfunctional attitudes) were measured at baseline and one-week follow up. RESULTS Completer analyses showed both imagery rescripting conditions and psychoeducation had significant impact on global eating psychopathology and body acceptance (d = 0.60-0.78). Psychoeducation did not impact secondary variables, whereas body imagery rescripting improved self-compassion and fear of self-compassion (d = 0.61-0.80) and general imagery rescripting improved dysfunctional attitudes (d = 0.82) compared to control. Intent to treat analyses had similar but slightly less robust results. DISCUSSION While three active groups had significant impact on the primary variables, imagery rescripting approaches had impact on other variables that maintain disordered eating. Future research should investigate the impact of combining psychoeducation and imagery rescripting in terms of impact on disordered eating.

Abstract
Stepped-care (SC) models for anxiety disorders are implemented on a large scale and are assumed to be as effective for the greater majority of patients as more intensive treatment schemes. To compare the outcomes of SC and international guideline-based treatment (Treatment as Usual: TAU) for panic disorder, a total of 128 patients were randomized to either SC or TAU (ratio 2: 1, respectively) using a computer generated algorithm. They were treated in four mental health care centres in the Netherlands after therapists had been trained in SC by a senior expert therapist. SC comprised 10-week guided self-help (pen-and-paper version) followed, if indicated, by 13-week manualized face-to-face cognitive behavioural therapy (CBT), with medication- if prescribed- kept constant. TAU consisted of 23-week regular face-to-face CBT (RCBT) with medication -when prescribed- also kept constant. The means of the attended sessions in the SC condition was 5.9 (SD = 4.8) for ITT and 9.6 (SD = 9.6) for the RCBT condition. The difference in the number of attended sessions between the conditions was significant (t(126) = -3.87, p < .001). Remission rates between treatment conditions did not differ significantly (SC: 44.5%; RCBT: 53.3%) and symptom reduction was similar. Stepping up SC treatment to face-to-face CBT showed a minimal additional effect. Importantly, drop-out rates differed significantly for the two conditions (SC: 48.2%; RCBT: 26.7%). SC was effective in the treatment of panic disorder in terms of symptom reduction and remission rate, but dropout rates were twice as high as those seen in RCBT, with the second phase of SC not substantially improving treatment response. However, SC required significantly less therapist contact time compared to RCBT, and more research is needed to explore predictors of success for guided self-help interventions to allow treatment intensity to be tailored to patients' needs and preferences.

Abstract
Evidence-based treatments (EBTs) have been well studied in outpatient and research settings to address a myriad of mental health concerns. Research studies have found benefits and challenges when implementing these interventions. However, less is known about the implementation of EBTs in acute and intensive treatment settings such as inpatient psychiatric hospitalization (IPH) units, partial hospitalization programs (PHPs), or intensive outpatient programs (IOPs). As a result, the specific benefits and challenges of providing EBTs in these settings are less clear. For example, challenges of implementing EBTs in IPHs, PHPs, and IOPs can include working within a multi-disciplinary team setting and sustaining trained staff. The current article provides an overview of implementing EBTs in IPHs PHPs, and IOPs. Current PHP, IOP, and IPH models of implementing evidence-based interventions along with strategies for engaging stakeholders, program development and implementation, and measurement are reviewed. Further considerations for sustainability and practice consideration are also provided.

Abstract
Despite initial data suggesting positive treatment outcomes for adolescent eating disorder day-hospital programmes (DHPs), existing studies have included limited follow-up, small samples, and a focus on restricting-type eating disorders. To address these gaps, we explored naturalistic outcomes for an adolescent eating disorders DHP. Adolescent participants (N = 265) completed measurements at treatment admission, discharge (n = 170), and various lengths of follow-up (n = 126; Mfollow up = 278.87 days). Results from multilevel models indicated significant increases in body weight for the anorexia nervosa group throughout treatment and maintenance of increased body weight from discharge to follow-up. In bulimic spectrum disorders, binge eating and purging significantly decreased from intake to discharge and did not change from discharge to follow-up. Across the entire sample, eating disorder symptoms decreased from intake to discharge and did not change from discharge to follow-up. Further, anxiety and depression decreased over the course of treatment and continued to decrease over the follow-up period. The current investigation represents the first study to explore longitudinal DHP outcomes within adolescent bulimic spectrum eating disorders. Our findings also highlight many challenges inherent in conducting naturalistic research; it is critical that the field continue to develop solutions to the barriers inherent in conducting longitudinal research on eating disorder treatment.

Abstract
Eating disorders cause a number of severely impairing symptoms that may require more intensive intervention that is available through outpatient therapy services. The PHP/IOP level of care may be an effective mode of treatment in these cases, but few studies have examined overall outcomes or treatment moderators for this level of care. Using a large sample from a PHP/IOP specifically designed for the treatment of eating disorders, the current study examines a variety of symptoms (eating disorder severity, quality of life, depression, etc.) from admission to discharge, as well as potential moderators of treatment, including demographic and clinical factors. Overall, the PHP/IOP level of care was found to improve treatment outcomes. Age, race, gender, and depression were found to moderate the change in quality of life and functional impairment. Additionally, patients diagnosed with anorexia nervosa had significantly lowered quality of life and greater eating disorder symptomatology than all other diagnoses. The results of this study can help to inform clinical practice and help guide in treatment decisions at the partial hospitalization level of care.

Abstract
Facing poor long-term outcome and high relapse rates in the treatment of bulimia nervosa, we developed an Internet-based aftercare program for women with severe and chronic bulimia nervosa following inpatient treatment based on previous experiences with self-directed targeted prevention and early intervention programs delivered online. The aim of the present study was to examine adherence to the program in detail, to explore potential variables that predict adherence and to analyze whether adherence affects outcomes. We analyzed data from 126 women in the intervention group of a randomized controlled trial. 107 women (85%) logged on to the program platform at least once. These women opened on average 42.8% (SD = 31.9%) of all assigned program pages. Adherence declined during the course of the intervention. Adherence was not associated with the number of outpatient treatment sessions received during the intervention period. Adherence was not related to overall illness severity or duration at baseline. However, excessive exercise at hospital discharge (which may be a sign of insufficient motivation to change eating disorder related behaviors) seems to play some small role in adherence. Adherence did not affect intervention outcomes. Based on our findings, we would like to advocate further research on online aftercare interventions for women with severe and chronic bulimia nervosa.

Abstract
The most widely researched treatment for bulimia nervosa (BN) and binge-eating disorder (BED) is cognitive behavioral therapy (CBT), a present-focused, active, skill-oriented treatment. However, despite the success of CBT, many patients fail to achieve sufficient rates of skill utilization (i.e., the frequency with which a patient practices or uses therapeutic skills) or adequate skill acquisition (i.e., the ability to successfully perform a skill learned in treatment) by the end of treatment and outcomes suffer as a result. One method for improving skill acquisition and utilization in patients with BN or BED could be the augmentation of in-person treatment with just-in-time adaptive interventions (JITAIs), which use smartphone technology to deliver real-time interventions during app-identified moments of need. The current article discusses how novel JITAI systems that utilize machine learning or other predictive algorithms could be used to detect momentary risk for eating disordered behavior and provide tailored interventions to enhance outcomes. We will consider technologies that may help reduce patient burden and suggest avenues for future research on developing acceptable and effective JITAIs that can be used as an adjunct to CBT protocols.

Abstract
BACKGROUND The Obsessive-Compulsive Treatment Efficacy randomised controlled Trial emerged from a research recommendation in National Institute for Health and Care Excellence obsessive-compulsive disorder (OCD) guidelines, which specified the need to evaluate cognitive-behavioural therapy (CBT) treatment intensity formats. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of two low-intensity CBT interventions [supported computerised cognitive-behavioural therapy (cCBT) and guided self-help]: (1) compared with waiting list for high-intensity CBT in adults with OCD at 3 months; and (2) plus high-intensity CBT compared with waiting list plus high-intensity CBT in adults with OCD at 12 months. To determine patient and professional acceptability of low-intensity CBT interventions. DESIGN A three-arm, multicentre, randomised controlled trial. SETTING Improving Access to Psychological Therapies services and primary/secondary care mental health services in 15 NHS trusts. PARTICIPANTS Patients aged ≥ 18 years meeting Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition criteria for OCD, on a waiting list for high-intensity CBT and scoring ≥ 16 on the Yale-Brown Obsessive Compulsive Scale (indicative of at least moderate severity OCD) and able to read English. INTERVENTIONS Participants were randomised to (1) supported cCBT, (2) guided self-help or (3) a waiting list for high-intensity CBT. MAIN OUTCOME MEASURES The primary outcome was OCD symptoms using the Yale-Brown Obsessive Compulsive Scale - Observer Rated. RESULTS Patients were recruited from 14 NHS trusts between February 2011 and May 2014. Follow-up data collection was complete by May 2015. There were 475 patients randomised: supported cCBT (n = 158); guided self-help (n = 158) and waiting list for high-intensity CBT (n = 159). Two patients were excluded post randomisation (one supported cCBT and one waiting list for high-intensity CBT); therefore, data were analysed for 473 patients. In the short term, prior to accessing high-intensity CBT, guided self-help demonstrated statistically significant benefits over waiting list, but these benefits did not meet the prespecified criterion for clinical significance [adjusted mean difference -1.91, 95% confidence interval (CI) -3.27 to -0.55; p = 0.006]. Supported cCBT did not demonstrate any significant benefit (adjusted mean difference -0.71, 95% CI -2.12 to 0.70). In the longer term, access to guided self-help and supported cCBT, prior to high-intensity CBT, did not lead to differences in outcomes compared with access to high-intensity CBT alone. Access to guided self-help and supported cCBT led to significant reductions in the uptake of high-intensity CBT; this did not seem to compromise patient outcomes at 12 months. Taking a decision-making approach, which focuses on which decision has a higher probability of being cost-effective, rather than the statistical significance of the results, there was little evidence that supported cCBT and guided self-help are cost-effective at the 3-month follow-up compared with a waiting list. However, by the 12-month follow-up, data suggested a greater probability of guided self-help being cost-effective than a waiting list from the health- and social-care perspective (60%) and the societal perspective (80%), and of supported cCBT being cost-effective compared with a waiting list from both perspectives (70%). Qualitative interviews found that guided self-help was more acceptable to patients than supported cCBT. Professionals acknowledged the advantages of low intensity interventions at a population level. No adverse events occurred during the trial that were deemed to be suspected or unexpected serious events. LIMITATIONS A significant issue in the interpretation of the results concerns the high level of access to high-intensity CBT during the waiting list period. CONCLUSIONS Although low-intensity interventions are not associated with clinically significant improvements in OCD symptoms, economic analysis over 12 months suggests that low-intensity interventions are cost-effective and may have an important role in OCD care pathways. Further research to enhance the clinical effectiveness of these interventions may be warranted, alongside research on how best to incorporate them into care pathways.

Study protocol and rationale for a randomized double-blinded crossover trial of phentermine-topiramate ER versus placebo to treat binge eating disorder and bulimia nervosa. Contemp Clin Trials 2018; 64:173-178. [PMID: 29038069 DOI: 10.1016/j.cct.2017.10.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2017] [Revised: 10/05/2017] [Accepted: 10/10/2017] [Indexed: 01/24/2023]
Abstract
INTRODUCTION Bulimia nervosa (BN) and binge eating disorder (BED) are associated with severe psychological and medical consequences. Current therapies are limited, leaving up to 50% of patients symptomatic despite treatment, underscoring the need for additional treatment options. Qsymia, an FDA-approved medication for obesity, combines phentermine and topiramate ER. Topiramate has demonstrated efficacy for both BED and BN, but limited tolerability. Phentermine is FDA-approved for weight loss. A rationale for combined phentermine/topiramate for BED and BN is improved tolerability and efficacy. While a prior case series exploring Qsymia for BED showed promise, randomized studies are needed to evaluate Qsymia's safety and efficacy when re-purposed in eating disorders. We present a study protocol for a Phase I/IIa single-center, prospective, double-blinded, randomized, crossover trial examining safety and preliminary efficacy of Qsymia for BED and BN. METHODS Adults with BED (n=15) or BN (n=15) are randomized 1:1 to receive 12weeks Qsymia (phentermine/topiramate ER, 3.75mg/23mg-15mg/92mg) or placebo, followed by 2-weeks washout and 12-weeks crossover, where those on Qsymia receive placebo and vice versa. Subsequently participants receive 8weeks follow-up off study medications. The primary outcome is the number of binge days/week measured by EDE. Secondary outcomes include average number of binge episodes, percentage abstinence from binge eating, and changes in weight/vitals, eating psychopathology, and mood. DISCUSSION To our knowledge this is the first randomized, double-blind protocol investigating the safety and efficacy of phentermine/topiramate in BED and BN. We highlight the background and rationale for this study, including the advantages of a crossover design.

Abstract
OBJECTIVE Early response to eating disorders treatment is thought to predict a later favourable outcome. A systematic review of the literature and meta-analyses examined the robustness of this concept. METHOD The criteria used across studies to define early response were summarised following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Diagnostic Test Accuracy methodology was used to estimate the size of the effect. RESULTS Findings from 24 studies were synthesized and data from 14 studies were included in the meta-analysis. In Anorexia Nervosa, the odds ratio of early response predicting remission was 4.85(95%CI: 2.94-8.01) and the summary Area Under the Curve (AUC) = .77. In Bulimia Nervosa, the odds ratio was 2.75(95%CI:1.24-6.09) and AUC = .67. For Binge Eating Disorder, the odds ratio was 5.01(95%CI: 3.38-7.42) and AUC = .71. CONCLUSION Early behaviour change accurately predicts later symptom remission for Anorexia Nervosa and Binge Eating Disorder but there is less predictive accuracy for Bulimia Nervosa.

Abstract
Predicting therapeutic outcome in the mental health domain is of utmost importance to enable therapists to provide the most effective treatment to a patient. Using information from the writings of a patient can potentially be a valuable source of information, especially now that more and more treatments involve computer-based exercises or electronic conversations between patient and therapist. In this paper, we study predictive modeling using writings of patients under treatment for a social anxiety disorder. We extract a wealth of information from the text written by patients including their usage of words, the topics they talk about, the sentiment of the messages, and the style of writing. In addition, we study trends over time with respect to those measures. We then apply machine learning algorithms to generate the predictive models. Based on a dataset of 69 patients, we are able to show that we can predict therapy outcome with an area under the curve of 0.83 halfway through the therapy and with a precision of 0.78 when using the full data (i.e., the entire treatment period). Due to the limited number of participants, it is hard to generalize the results, but they do show great potential in this type of information.

Abstract
This article reviews the most recent treatment literature for anorexia nervosa, bulimia nervosa, and binge eating disorder and serves as a guide for recommended readings and therapist resources. The primary focus is on empirically tested treatment modalities; for each of these approaches reviewed, the theoretical background, nature of the intervention, and existing empirical support are summarized. The article also presents less researched, albeit promising, approaches to eating disorder treatment, describing the rationale and available research. A focus on multicultural issues, including the paucity of eating disorder treatment research among participants of color, and suggestions for building research and enhancing treatment effectiveness with ethnic minority clients, is incorporated throughout. Recommendations concerning pressing research needs are made, and a summary of clinical recommendations for each disorder is formulated.

Abstract
OBJECTIVE The objective of this study was to review the current eating disorders outcome literature after residential or partial hospitalization programme (PHP) treatment. METHOD Articles were identified through a systematic search of PubMed and PsycINFO. RESULTS Twenty-two PHP and six residential treatment studies reported response at discharge and tended to find improvement. Fewer studies (nine PHP and three residential) reported outcome at some interval after discharge from treatment. These tended to find sustained improvement. A substantial proportion of patients were lost to follow-up, particularly for residential treatment. Only two follow-up studies used controlled trials; both showed efficacy for PHP compared with inpatient treatment with regard to maintaining symptom remission. CONCLUSIONS Improvement at discharge may not predict long-term outcome. Long-term follow-up studies were confounded by high dropout rates. While higher levels of care may be essential for reversing malnutrition, there remains a lack of controlled trials showing long-term efficacy, particularly for residential treatment settings.

Abstract
OBJECTIVE This case report aims to (1) describe the development and refinement of a smartphone application for eating disorder self-monitoring; (2) characterize its users in terms of demographic and clinical characteristics; and (3) explore its feasibility and utilization as a self-monitoring tool. METHOD We developed a mobile phone application through which people with eating disorders can self-monitor meals, emotions, behaviors, and thoughts. The application also included positive reinforcement, coping skill suggestions, social support, and feedback components. The app was made available on two Internet app stores. Data include number of downloads and subsequent usage statistics, consumer ratings on app-stores are used as indicators of satisfaction, anonymous aggregate demographic data and Eating Disorder Examination Questionnaire scores from 57,940 individuals collected over a two-year period. RESULTS The app demonstrated population-level utilization with over 100,000 users over a two-year period. Almost 50% percent of users stated that they are not currently receiving clinical treatment and 33% reported they had not told anyone about their eating disorder. A surprising number of people with severe problems are using the app. DISCUSSION Smartphone apps have the capacity to reach and engage traditionally underserved individuals with eating disorders at a large scale. Additional work is indicated for the evaluation of the clinical effectiveness of applications for specific user groups and in clinical treatment contexts.

Abstract
OBJECTIVE Motivational Interviewing (MI) is a collaborative therapy that focuses on strengthening a person's internal motivation to change. Research suggests that MI may be helpful for treating binge eating; however, findings are limited and little is known about how MI for binge eating compares to active therapy controls. The present study aimed to build on current research by comparing MI as a prelude to self-help treatment for binge eating with psychoeducation as a prelude to self-help treatment for binge eating. METHOD Participants with full or subthreshold DSM-IV Binge Eating Disorder or nonpurging Bulimia Nervosa were randomly assigned to receive either 60 minutes of MI followed by a self-help manual (n = 24) or 60 minutes of psychoeducation followed by a self-help manual (n = 21). Questionnaires were completed pre- and postsession, and at 1 and 4 months postsession. RESULTS MI significantly increased readiness to change and confidence in ability to control binge eating, whereas psychoeducation did not. No group differences were found when changes in eating disorder attitudes and behaviors were examined. DISCUSSION MI offers benefits for increasing motivation and self-efficacy. However, it may not be a uniquely effective treatment approach for reducing binge eating.

Abstract
BACKGROUND Stepped care service delivery models involve treatments that become increasingly intense through successive steps, with patients re-assigned via pre-defined decision criteria. This article reviews the clinical effectiveness of stepped care systems for depression in working age adults. METHODS Systematic literature review of quantitative clinical outcome evidence comprising 14 controlled and uncontrolled studies meeting specified criteria. Principal outcomes were (a) recovery rates, defined as patients no longer meeting clinical cut-off criteria for the specific outcome measure and (b) treatment response rates, defined as a 50% decrease in outcome measure score. RESULTS Stepped care systems had recovery rates ranging predominantly between 40% and 60% and response rates approximating 60%. Studies comparing stepped care with usual/enhanced usual care tended to find significant differences favouring stepped care. The median recovery odds ratio was 1.31 (interquartile intervals of 1.05 and 1.66; k=7 studies). The median comparative Cohen's d effect size estimate was 0.41 (interquartile intervals 0.25 and 0.45; k=5 studies). LIMITATIONS The inclusion of uncontrolled studies could be seen as reducing the overall quality of evidence and a meta-analysis was not included due to limitations with the available data. CONCLUSIONS Evidence suggested that stepped care interventions for depression are at least as effective as usual care. However, the clinical and organisational superiority of stepped care is yet to be scientifically verified. Differential benefits of stepped care may ultimately depend on service quality. Further research investigating and comparing the specific components and configurations of stepped care interventions are indicated.

Abstract
The management of many health disorders often entails a sequential, individualized approach whereby treatment is adapted and readapted over time in response to the specific needs and evolving status of the individual. Adaptive interventions provide one way to operationalize the strategies (e.g., continue, augment, switch, step-down) leading to individualized sequences of treatment. Often, a wide variety of critical questions must be answered when developing a high-quality adaptive intervention. Yet, there is often insufficient empirical evidence or theoretical basis to address these questions. The Sequential Multiple Assignment Randomized Trial (SMART)-a type of research design-was developed explicitly for the purpose of building optimal adaptive interventions by providing answers to such questions. Despite increasing popularity, SMARTs remain relatively new to intervention scientists. This manuscript provides an introduction to adaptive interventions and SMARTs. We discuss SMART design considerations, including common primary and secondary aims. For illustration, we discuss the development of an adaptive intervention for optimizing weight loss among adult individuals who are overweight.

Abstract
ABSTRACT Eating disorders often develop during adolescence and young adulthood, and are associated with significant psychological and physical burden. Identifying evidence-based interventions is critical and there is need to take stock of the extant literature, to inform clinical practice regarding well-researched interventions and to direct future research agendas by identifying gaps in the evidence base. AIM To investigate and quantify the nature and distribution of existing high-quality research on the prevention and treatment of eating disorders in young people using evidence mapping methodology. METHOD A systematic search for prevention and treatment intervention studies in adolescents and young adults (12-25 years) was conducted using EMBASE, PSYCINFO and MEDLINE. Studies were screened and mapped according to disorder, intervention modality, stage of eating disorder and study design. Included studies were restricted to controlled trials and systematic reviews published since 1980. RESULTS The eating disorders evidence map included 197 trials and 22 systematic reviews. Prevention research was dominated by trials of psychoeducation (PE). Bulimia nervosa (BN) received the most attention in the treatment literature, with cognitive behavioural therapy (CBT) and antidepressants the most common interventions. For anorexia nervosa (AN), family based therapy (FBT) was the most studied. Lacking were trials exploring treatments for binge eating disorder (BED) and eating disorder not otherwise specified (EDNOS). Relapse prevention strategies were notably absent across the eating disorders. CONCLUSIONS Despite substantial literature devoted to the prevention and treatment of eating disorders in young people, the evidence base is not well established and significant gaps remain. For those identified as being at-risk, there is need for prevention research exploring strategies other than passive PE. Treatment interventions targeting BED and EDNOS are required, as are systematic reviews synthesising BN treatment trials (e.g., CBT, antidepressants). FBTs for AN require investigation against other validated psychological interventions, and the development of relapse prevention strategies is urgently required. By systematically identifying existing interventions for young people with eating disorders and exposing gaps in the current literature, the evidence map can inform researchers, funding bodies and policy makers as to the opportunities for future research.

Abstract
The first Autism Research Matrix (IACC, 2003) listed the identification of behavioural and biological markers of risk for autism as a top priority. This emphasis was based on the hypothesis that intervention with infants at-risk, at an early age when the brain is developing and before core autism symptoms have emerged, could significantly alter the developmental trajectory of children at risk for the disorder and impact long-range outcome. Research has provided support for specific models of early autism intervention (e.g., Early Start Denver Model) for improving outcomes in young children with autism, based on both behavioural and brain activity measures. Although great strides have been made in ability to identify risk markers for autism in younger infant/toddler samples, how and when to intervene during the prodromal state remains a critical question. Emerging evidence suggests that abnormal brain circuitry in autism precedes altered social behaviours; thus, an intervention designed to promote early social engagement and reciprocity potentially could steer brain development back toward the normal trajectory and remit or reduce the expression of symptoms.

Abstract
There is a growing body of research on manualized self-help interventions for bulimia nervosa (BN) and binge eating disorder (BED). Study and treatment dropout and adherence represent particular challenges in these studies. However, systematic investigations of the relationship between study, intervention and patient characteristics, participation, and intervention outcomes are lacking. We conducted a systematic literature review using electronic databases and hand searches of relevant journals. In metaregression analyses, we analyzed study dropout as well as more specific measures of treatment participation in manualized self-help interventions, their association with intervention characteristics (e.g. duration, guidance, intervention type [bibliotherapy, CD-ROM or Internet based intervention]) and their association with treatment outcomes. Seventy-three publications reporting on 50 different trials of manualized self-help interventions for binge eating and bulimia nervosa published through July 9th 2012 were identified. Across studies, dropout rates ranged from 1% to 88%. Study dropout rates were highest in CD-ROM interventions and lowest in Internet-based interventions. They were higher in samples of BN patients, samples of patients with higher degrees of dietary restraint at baseline, lower age, and lower body mass index. Between 6% and 88% of patients completed the intervention to which they had been assigned. None of the patient, study and intervention characteristics predicted intervention completion rates. Intervention outcomes were moderated by the provision of personal guidance by a health professional, the number of guidance sessions as well as participants' age, BMI, and eating disorder related attitudes (Restraint, Eating, Weight and Shape Concerns) at baseline (after adjusting for study dropout and intervention completion rates). Guidance particularly improved adherence and outcomes in samples of patients with bulimia nervosa; specialist guidance led to higher intervention completion rates and larger intervention effects on some outcomes than non-specialist guidance. Self-help interventions have a place in the treatment of BN and BED, especially if the features of their delivery and indications are considered carefully. To better determine who benefits most from what kind and "dosage" of self-help interventions, we recommend the use of consistent terminology as well as uniform standards for reporting adherence and participation in future self-help trials.

Abstract
BACKGROUND Depressive and eating disorder symptoms are highly comorbid. To date, however, little is known regarding the efficacy of existing programs in decreasing concurrent eating disorder and depressive symptoms. METHODS We conducted a systematic review of selective and indicated controlled prevention and early intervention programs that assessed both eating disorder and depressive symptoms. RESULTS We identified a total of 26 studies. The large majority of identified interventions (92%) were successful in decreasing eating disorder symptoms. However fewer than half (42%) were successful in decreasing both eating disorder and depressive symptoms. Intervention and participant characteristics did not predict success in decreasing depressive symptoms. CONCLUSIONS Indicated prevention and early intervention programs targeting eating disorder symptoms are limited in their success in decreasing concurrent depressive symptoms. Further efforts to develop more efficient interventions that are successful in decreasing both eating disorder and depressive symptoms are warranted.

Abstract
Purpose
– This paper describes the development of a novel integrative self-directed treatment tool which uses cognitive behavioural therapy techniques to reduce anxiety symptoms in patients presenting to treatment for alcohol-related problems. More specifically, the purpose of this paper is to explore patient and health practitioner perceptions of the booklet, in order to determine its suitability and utility in the context of existing alcohol treatment services. The extent of cross-informant agreement between patient and health practitioner responses is also examined.
Design/methodology/approach
– This research utilises a cross-sectional qualitative research design using semi-structured interview methods with patients presenting to hospital for alcohol-related diseases/illnesses/accidents/injuries (n=15) and practitioners (n=10) working at inpatient, outpatient and residential substance treatment facilities.
Findings
– The present study found that the majority of patients (80 per cent) and practitioners (90 per cent) expressed a motivation to utilise the proposed booklet, agreeing that the booklet was a practical, achievable and educational resource for patients suffering from co-occurring anxiety symptoms in substance abuse facilities. Participants outlined limitations of the resource, suggesting that the booklet would be most suitable for patients with moderate to high cognitive ability, who also exhibit a motivation to change alcohol consumption and have access to additional support.
Practical implications
– Findings from the present study suggest that the booklet may be most effective in improving treatment accessibility and patient treatment seeking behaviours; rather than reducing practitioner-patient contact.
Originality/value
– This paper focuses on the development and utility of a novel resource suitable for substance abuse treatment facilities. The findings and feedback produced from the present study can assist with modifications of the intervention and in improving the effectiveness of future trials.

Decision Making in Stepped Care: How Do Therapists Decide Whether to Prolong Treatment or Not? Behav Cogn Psychother 2013; 43:328-41.

Abstract
Background: The efficiency of stepped care systems partly relies on systematic monitoring of patient outcomes and timely decisions to “step up” patients without any clear therapeutic gains to the next level of treatment. Qualitative evidence has suggested that this does not occur consistently, nor always congruently with clinical guidelines. Aims: To investigate factors that influence psychological therapists’ decisions to prolong or to conclude treatment in cases with little evidence of therapeutic gains. Method: Eighty-two clinicians in stepped care services completed questionnaires about the likelihood of “holding” non-improving patients in treatment, and factors associated with referrals and holding (FARAH-Q). The factor structure, internal consistency and test-retest reliability of the measures was examined prior to assessing correlations between FARAH-Q items and likelihood of holding. Results: A 4-factor solution indicated that clinicians’ decision making is influenced by a complex interplay between beliefs, attitudes, subjective norms and self-efficacy. Correlational analysis indicated that holding is more likely to happen if there are perceived barriers to refer the patient for further treatment, if the therapist likes the patient and has a good therapeutic alliance, and if the therapist feels confident that s/he has the ability to achieve a positive outcome by prolonging treatment. Conclusions: Decisions to prolong or conclude treatment are not only influenced by evidence and guidelines, but also subjective beliefs, norms and attitudes. Understanding this decision making process is relevant to clinicians and supervisors interested in enhancing the efficiency of stepped care.

Abstract
Given the well-documented shortage of cognitive-behavioral therapy (CBT) for eating disorders, there is a compelling need for advances in dissemination. Guided self-help based on cognitive-behavioral principles (CBTgsh) provides a robust means of improving implementation and scalability of evidence-based treatment for eating disorders. It is a brief, cost-effective treatment that can be implemented by a wide range of mental health providers, including non-specialists, via face-to-face contact and internet-based technology. Controlled studies have shown that CBTgsh can be an effective treatment for binge eating disorder and bulimia nervosa, although it is contraindicated for anorexia nervosa. Several studies have shown that CBTgsh can be as effective as more complex specialty therapies and that it is not necessarily contraindicated for patients with comorbid conditions. Mental health providers with relatively minimal professional credentials have in some studies obtained results comparable to specialized clinicians. Establishing the nature of optimal "guidance" in CBTgsh and the level of expertise and training required for effective implementation is a research priority. Existing manuals used in CBTgsh are outdated and can be improved by incorporating the principles of enhanced transdiagnostic CBT. Obstacles to wider adoption of CBTgsh are identified.

Weight suppression as a predictor of weight gain and response to intensive behavioral treatment in patients with anorexia nervosa. Behav Res Ther 2012; 50:266-74.

Abstract
Previous studies have documented that weight suppression (a person's highest adult weight minus current weight) predicts weight gain and disordered eating symptoms during treatment of bulimia spectrum disorders, but no research has examined weight suppression in individuals with anorexia nervosa (AN). Thus, this study sought to characterize weight suppression in a large sample of patients with AN (N = 185), and to evaluate whether weight suppression at admission for intensive behavioral treatment predicts weight gain and clinical outcomes at discharge. Weight suppression varied from 0 kg to 78 kg (M [SD] = 17.1 [10.8] kg) in AN patients. Higher levels of weight suppression predicted greater total weight gain, a faster rate of weight gain, and bulimic symptoms during intensive treatment even after controlling for body mass index on admission, length and type of intensive treatment received, restricting versus binge-eating/purging AN subtype, and other predictors of study outcomes. These findings converge with previous research documenting the clinical significance of weight suppression in the treatment of eating disorders. Future work is needed to replicate the current findings, and examine whether weight suppression predicts the course of AN following discharge from intensive treatment.

Abstract
Obesity is associated with early mortality and has overtaken smoking as the health problem with the greatest impact on quality of life, mortality, and morbidity. Despite public health initiatives and numerous commercial enterprises focusing on weight loss, obesity rates continue to rise. In part, this is because obesity is a multifaceted, complex illness, impacted by numerous social, psychological, and behavioural factors that are unrecognized in most current initiatives. One significant factor associated with obesity is mental illness. While having a psychiatric illness does not make weight gain inevitable, it does often require that additional tools be added to lifestyle recommendations around diet and exercise. The following article reviews the common approaches to obesity management and addresses how these strategies can be implemented in psychiatric care. It is important that health professionals involved in the care of people with a mental illness become familiar with the interventions available to control and treat the obesity epidemic, as this will improve treatment compliance and ultimately lead to improved physical and psychological outcomes.

Abstract
BACKGROUND For the German treatment guidelines for eating disorders, the literature on psychological treatment of anorexia nervosa (AN) was reviewed systematically. As a common meta-analysis of randomized clinical trials proved to be impossible, a review of all available clinical trials was conducted, statistically integrating standardized mean change scores. Research questions comprised differential effects of therapeutic techniques and settings as well as determining which weight gains could be expected. METHODS After an extensive literature search, studies were selected, rated by 3 independent raters. Weight gain as the main outcome criterion was transformed into standardized mean change scores. Effect sizes were checked for homogeneity. RESULTS 57 studies containing 84 treatment arms and 2,273 patients could be integrated. Studies differed considerably in quality. The strongest bias identified was reporting selectively on completers or failures, versus intention-to-treat samples. No significant differences between effect sizes could be identified concerning treatment setting, technique or patient characteristics. If treatment time is taken into account, inpatient treatment produced a faster weight gain than outpatient treatment. CONCLUSION The study describes weight gains which can be reached in outpatient and inpatient settings. It yielded no salient results speaking for a certain therapy technique, setting or procedure. Treatment guidelines for psychological treatment of AN still have to rely on lower level evidence.

Abstract
BACKGROUND Depressive and anxiety disorders are common in general practice but not always treated adequately. Introducing stepped care might improve this. In this randomized trial we examined the effectiveness of such a stepped care model. METHODS The study population consisted of primary care attendees aged 18-65 years with minor or major DSM-IV depressive and/or anxiety disorders, recruited through screening. We randomized 120 patients to either stepped care or care as usual. The stepped care program consisted of (1) watchful waiting, (2) guided self-help, (3) short face-to-face problem solving treatment and (4) pharmacotherapy and/or specialized mental health care. Patients were assessed at baseline and after 8, 16 and 24 weeks. RESULTS Symptoms of depression and anxiety decreased significantly over time for both groups. However, there was no statistically significant difference between the two groups (IDS: P = 0.35 and HADS: P = 0.64). The largest, but not significant, effect (d = -0.21) was found for anxiety on T3. In both groups approximately 48% of the patients were recovered from their DSM-IV diagnosis at the final 6 months assessment. CONCLUSIONS In summary we could not demonstrate that stepped care for depression and anxiety in general practice was more effective than care as usual. Possible reasons are discussed.

Abstract
The purpose of this study was to assess the predictive validity of guidelines for allocating outpatients with an alcohol-use disorder to different levels of care in routine alcohol outpatient treatment facilities. It was hypothesized that patients matched to the recommended level of care would have (a) better outcomes than patients treated at a less intensive level of care, and (b) outcomes equivalent to patients treated at a more intensive level of care. Patients at two Dutch substance-abuse treatment centers who completed intake and were allocated at either a brief or standard outpatient treatment (n=471) were followed prospectively to determine differential outcomes for those who were and were not treated at the recommended level of car. The former patients were allocated according to an algorithm based on their treatment history, addiction severity, psychiatric impairment and social stability at baseline. 52.9% of the original sample was successfully contacted for follow-up 11 months after intake. Outcome was measured in terms of self-reported alcohol use 30 days prior to follow up and changes in number of excessive and nonexcessive drinking days between intake and follow up. Only 21% of the patients were matched to the level of care according to the guidelines. Patients allocated to the recommended level of care did not have better outcomes than those treated at a less intensive level of care, but they had outcomes comparable to patients treated at a more intensive level of care. The a priori allocation guidelines were followed for only a minority of the patients, and using them did not improve treatment outcome. Further work is needed to improve the content of the treatment allocation guidelines.

Abstract
The link between negative affect and binge eating in those with binge eating disorder (BED) has been well established. The present study examined the efficacy of a treatment for BED designed to increase recognition and regulation of negative emotion, replicating and extending a previous investigation (Clyne, C., & Blampied, N.M. [2004]. Training in emotion regulation as a treatment for binge eating: A preliminary study. Behaviour Change, 21, 269-281) by including a control group, a larger number of participants, and formal diagnoses rather than classifying binge eating symptomatology from self-report questionnaires. Twenty-three women diagnosed with subthreshold or full syndrome BED (using the Eating Disorders Examination) participated in a treatment program that focused on increasing emotional regulation skills. Each participant completed the Eating Disorders Examination Questionnaire, the Binge Eating Scale, the Emotional Eating Scale, and completed self-monitoring records of binge episodes. Binge abstinence rates following treatment (post-treatment and 1 year follow-up were 78% and 87% respectively) were comparable to other empirically supported treatments for BED. Other positive changes in eating and general pathology were observed. These effects were well-maintained up to 1 year later.

Abstract
Stepped-care approaches may offer a solution to delivering accessible, effective and efficient services for individuals with depression. In stepped care, all patients commence with a low-intensity, low-cost treatment. Treatment results are monitored systematically, and patients move to a higher-intensity treatment only if necessary. We deliver a stepped-care model targeting patients with depression. The first step consists of "watchful waiting", as half of all patients with a depressive episode recover spontaneously within 3 months. The second step, guided self-help, is the key element of the stepped-care model. Guided self-help, especially when offered through the internet, is effective and cost-efficient. The third step consists of brief face-to-face psychotherapy. Finally, in the fourth step, longer-term face-to-face psychotherapy and antidepressant medication might be considered. Patients are monitored by one person, a care manager, who is responsible for the decision to step up to the next treatment and for continuity of care. The different treatments within the stepped-care model are evidence-based. Data on cost-effectiveness of the full model are still scarce, but we recently demonstrated that the incidence of new cases of depression and anxiety could be halved by introducing stepped care. Effects of web-based guided self-help could be enhanced by incorporating them in a stepped-care model.

METHOD In Study 1, 60 adults completed assessments before and after a series of two groups; in Study 2, 21 adults also completed an assessment five weeks prior to the first group to identify time-related changes in symptoms. RESULTS Study 1 participants improved across domains, whereas Study 2 analyses also examining time-related changes showed improvements in eating self-efficacy, shame, guilt, and pride, but not in eating pathology. DISCUSSION Psychoeducational groups may help improve symptoms including eating pathology, eating self-efficacy, shame, guilt, and pride among chronically-ill adults with eating concerns.

Abstract
This article addresses less developed areas of clinical research that are of great importance for better understanding the therapeutic process along the continuum of care in youth with alcohol and other substance use disorders (AOSUD). These include the rationale, design, mechanisms of behavior change (MBCs), implementation, monitoring, and outcome-based modification of treatment continuum for youth with AOSUD. The specific objectives are: (1) present current knowledge pertaining to the pretreatment phase including the effect of baseline assessment on treatment outcome; (2) address potential MBCs in treatment; (3) discuss the importance of aftercare, also known as continued care, to prevent postintervention relapse; (4) consider how reconceptualization of therapeutic paradigms might advance the field, in particular treatment algorithm or adaptive treatment strategies addressing poor response to treatment.

Abstract
Many published articles have documented the impact of prostate-cancer treatment on sexual functioning in men treated for localized disease. Surprisingly, the literature on interventions to rehabilitate men's sexual functioning is much more limited. In this article, we review the sexual-rehabilitation interventions for prostate-cancer patients and identify a number of common themes across interventions. We also identify areas where further research is needed and propose a conceptual model based on psychologic and nursing theories and informed by the published research.

Abstract
AIMS To provide an overview over empirical evidence regarding stepped care approaches that include psychotherapies. To present own preliminary study results in alcohol dependent patients. METHODS Publications were searched in the databases Medline, PsycINFO and the internet search engine Google Scholar. Inclusion criteria were psychosocial treatment and psychiatric disorders. Our own study consists of two steps. In step 1 patients receive anti-craving medication or placebo and Medical Management (MM). After a relapse to heavy drinking patients can step up and after randomization they either continue with the same treatment or they receive additional alcoholism specific psychotherapy (ASP). RESULTS Evidence suggests that stepped care might be efficacious in patients with obsessive-compulsive behavior and depression. There is no evidence for efficacy in problem drinkers. Results of our own study show that the completer rate in MM alone is higher than in ASP with MM, but there are no significant differences concerning age, sex and disease severity between completer and non-completer in both study arms. CONCLUSIONS Further research with regard to stepped care in alcohol dependent patients is needed. An introduction of the psychotherapy at earlier stages might be sensible.

Abstract
This review of the current status of theoretically based behavioral research for chronic illness management makes the following points: (a) Behavioral interventions have demonstrated effectiveness for improving health outcomes using biomedical indicators, (b) current interventions are too costly and time consuming to be used in clinical and community settings, (c) translation of the conceptual models generated from studies of the problem-solving processes underlying self-management and the relationship of these processes to the self system and cultural and institutional contexts suggest new avenues for developing effective and efficient cognitive-behavioral interventions, and (d) it is proposed that integration of the conceptual developments in self-management with new approaches to the design of clinical trials can generate tailored, behavioral interventions that will improve quality of care.

Abstract
In the past 40 years, cognitive-behavior therapy (CBT) has emerged as the initial treatment of choice for patients with mild to moderate depression, anxiety disorders and other problems. In this paper, we discuss issues related to the dissemination and implementation of CBT in various practice settings as well as the use of manuals, computers, the telephone, and the Internet to aid dissemination and implementation. We review key aspects of CBT dissemination, such as the reach of CBT, models of dissemination, and obstacles and barriers to dissemination including patient interest, therapist training and research priorities. The effectiveness of manualized programs is considered, as well as the increasing sophistication of computer-assisted therapy. Stepped-care approaches are discussed as a viable solution to some of these barriers. We provide two examples of successful CBT dissemination, the Staying Free program, a smoking cessation program for inpatients, and the Improving Access to Psychological Therapies program in Britain, which aims to improve access to psychological therapy. We argue that two critical factors will determine the success of implementation of CBT in this century: 1) mandated outcomes and 2) leadership.

Abstract
OBJECTIVE This paper considers whether the criteria currently used to classify the diagnosis of binge eating disorder (BED) are valid and appropriate. METHOD We review evidence that reflects on the validity of the current criteria for binge eating episodes and BED, using literature retrieved through major psychology and psychiatry search engines (e.g., PsycInfo, PubMed). RESULTS Evidence from experimental research points to the relative importance of episode frequency, the amount of food consumed at episodes, the subjective sense of loss of control over eating, and several additional criteria associated with binge episodes in BED. Evidence on the differences in psychopathology between BED and bulimia nervosa and between BED and obesity without binge eating, as related to diagnostic criteria, is reviewed. CONCLUSION Although evidence concerning the diagnostic criteria of BED is mixed, broadening certain diagnostic criteria for binge eating episodes and BED might more accurately reflect the research literature and increase the number of individuals eligible for inclusion in treatment programs.
