Abstract
BACKGROUND Eating disorder (ED) research has embraced a network perspective of psychopathology, which proposes that psychiatric disorders can be conceptualized as a complex system of interacting symptoms. However, existing intervention studies using the network perspective have failed to find that symptom reductions coincide with reductions in strength of associations among these symptoms. We propose that this may reflect failure of alignment between network theory and study design and analysis. We offer hypotheses for specific symptom associations expected to be disrupted by an app-based intervention, and test sensitivity of a range of statistical metrics for identifying this intervention-induced disruption. METHODS Data were analyzed from individuals with recurrent binge eating who participated in a randomized controlled trial of a cognitive-behavioral smartphone application. Participants were categorized into one of three groups: waitlist (n = 155), intervention responder (n = 49), and intervention non-responder (n = 77). Several statistical tests (bivariate associations, network-derived strength statistics, network invariance tests) were compared in ability to identify change in network structure. RESULTS Hypothesized disruption to specific symptom associations was observed through change in bivariate correlations from baseline to post-intervention among the responder group but were not evident from symptom and whole-of-network based network analysis statistics. Effects were masked when the intervention group was assessed together, ignoring heterogeneity in treatment responsiveness. CONCLUSION Findings are consistent with our contention that study design and analytic approach influence the ability to test network theory predictions with fidelity. We conclude by offering key recommendations for future network theory-driven interventional studies.

Abstract
OBJECTIVES Binge spectrum disorders are prevalent worldwide. Psychiatric and medical comorbidities are common, and societal costs are significant. Evidence-based treatment remains underutilized. Cognitive behavioral therapy is the recommended first-line treatment, but pharmacotherapy may be easier to access. INTERVENTIONS Meta-analytic evidence directly comparing cognitive behavioral therapy with pharmacotherapy is lacking. We aimed to compare the effects of cognitive behavioral therapy interventions with any pharmacological treatment for binge spectrum disorders. We searched PubMed, Embase, CENTRAL, ClinicalTrials.gov and reference lists for randomized controlled trials comparing cognitive behavioral therapy with any pharmacotherapy for bulimia nervosa/binge eating disorder and performed pairwise meta-analytic evaluations. PRIMARY OUTCOMES Primary outcomes are remission and frequency of binges. Secondary outcomes are frequency of purges, response, eating disorder psychopathology, weight/body mass index, depression, anxiety, quality of life and dropouts. RESULTS Eleven randomized controlled trials comparing cognitive behavioral therapy with fluoxetine/imipramine/desipramine/methylphenidate/sibutramine were identified (N = 531). Cognitive behavioral therapy was superior to antidepressants in terms of remission, frequency of binges and eating disorder psychopathology. There were no statistically significant differences for any of the individual cognitive behavioral therapy vs drug comparisons in terms of response/depression/anxiety/weight/quality of life/dropouts. Cognitive behavioral therapy was not superior to sibutramine/methylphenidate for the primary outcomes. CONCLUSIONS Data are scarce, comparisons underpowered and, considering the inherent methodological limitations of psychotherapy trials, questions arise regarding the presumed superiority of cognitive behavioral therapy. Further research is needed.

Abstract
In the twenty years since the publication of the most widely used treatment manuals describing evidence-based therapies for eating disorders, there have been some substantial advances in the field. New methods of delivering treatments have been trialled and our perception of mental health has advanced; significant cultural changes have led to shifts in our societal landscape; and new technologies have allowed for more in-depth research to be conducted. As a result, our understanding of eating disorders and their treatment has broadened considerably. However, these new insights have not necessarily been translated into improved clinical practice. This paper highlights the changes we consider to have had the greatest impact on our work as experienced clinical psychologists in the field and suggests a list of new learnings that might be incorporated into clinical practice and research design.

Abstract
BACKGROUND A large proportion of patients with eating disorders (ED) report experiences of childhood trauma. Latent trajectory analysis in ED samples reveals the complexities in course and outcome and can explore the long-term impact of adverse experiences in childhood. METHOD A total of 84 patients with longstanding ED were included. ED symptoms were assessed by the Eating Disorder Examination interview at discharge from inpatient treatment, and at 1-, 2-, 5-, and 17-year follow-up, respectively. Change over time was examined using growth mixture modeling, allowing the number of trajectories to emerge through the data. Prevalence of childhood trauma was assessed, and its relation to class membership was tested. RESULTS We identified four distinct classes: patients with (a) a continuous improvement in the entire follow-up period, and scores within normal range at the end, "continuous improvement" (54.8%); (b) a high symptom level at baseline and moderate decrease over time, "high and declining" (22.6%); (c) initial ED scores below clinical cut-off and stable symptoms throughout the course, "consistently low" (14.3%); and (d) with high scores initially, and a significant increase in symptoms over time, "high and increasing" (8.3%). A history of childhood sexual abuse (CSA) was overrepresented in classes with persistently high symptom levels and poor long-term outcome DISCUSSION: Patients with longstanding ED displayed considerable diversity in trajectories of symptom change across 17 years. To improve long-term outcome, enhanced treatment of sequelae from CSA seems essential. PUBLIC SIGNIFICANCE Patients with longstanding eating disorders displayed four different trajectories of change in a 17-year follow-up study. Although there were significant changes over time, the majority of patients remained within similar symptom levels as they presented with at discharge from inpatient treatment. Exposure to childhood maltreatment was common within the sample. Childhood sexual abuse predicted poor long-term outcome, which highlights the importance of trauma informed care.

Abstract
Bulimia Nervosa is a disorder with high rates of psychiatric and medical comorbidity and substantial societal costs. Cognitive Behavioural Therapy is considered the preferred treatment, but access can be problematic. Pharmacotherapy is more accessible but remains significantly underutilised. We aimed to assess the efficacy, tolerability, and safety of all available forms of pharmacotherapy for the treatment of bulimia nervosa. We conducted a comprehensive search of PubMed, EMBASE, CENTRAL, ClinicalTrials.gov, and reference lists of relevant articles up until April 2023. The primary outcomes were remission and binge frequency. 52 randomised controlled trials (RCTs) involving 3313 participants were included in the meta-analysis. Overall, no significant difference was observed between drugs and placebo in terms of remission; however, the available data were limited. Notably, drugs, particularly antidepressants, demonstrated a significant reduction in the frequency of binge episodes compared to placebo. Antidepressants were also found to be more effective than placebo in terms of treatment response and other clinically meaningful outcomes. An important limitation is that few RCTs were available for individual drugs. Our findings provide evidence supporting the increased utilisation of pharmacotherapy in clinical practice and underscore the need for further research involving larger populations and a broader range of outcomes.

Abstract
BACKGROUND Those who suffer from eating disorders often experience serious impairment in quality of life and the majority never receive treatment. Treatment availability may be increased by implementing methods that demand less resources and are more easy accessible such as internet-based treatments, but knowledge about their effects is still insufficient. The study evaluated effects of two types of internet-based cognitive behavioral therapy and a structured day patient program, the latter being a standard treatment at an eating disorder clinic at the time for the study. METHODS 150 participants with bulimic eating disorders randomized to two types of internet based treatments (one pure online treatment and one based on a self-help guide in book-format) or an intensive 16-week day patient program. The number of participants that started treatment was 120 of which 98 in internet treatment and 22 in the day program. Outcome assessments were carried out at baseline, post treatment, and at one-year follow-up. RESULTS All treatments were associated with significantly improved eating disorder pathology, self-image, and clinical impairment. Although the day program generally showed larger effects, only one significant difference found was in diagnostic remission post treatment; 51 % of the participant was in remission in internet treatment and 88 % in the day program. At one-year follow-up, participants in the internet treatments had continued to improve, whereas in the day patient program the effect sustained. Internet treatment had a 36 % drop out rate, there were no dropouts found in the day program. CONCLUSIONS All treatments were comparable in effect at follow-up, suggesting that internet treatment is a conceivable alternative to standard treatment. Internet treatment in a book-based format was also equally effective as a pure online format. Internet delivered cognitive behavioral treatment forms can make important contributions to achieve increased access to treatment for patients with bulimic eating disorders. Future research and clinical implications for internet delivered treatments in eating disorder services are discussed.

Understanding the role of positive body image during digital interventions for eating disorders: Secondary analyses of a randomized controlled trial. Body Image 2022; 43:1-7.

Abstract
Despite growing interest in the possible link between positive body image and eating disorder (ED) symptoms, little is known about what role this adaptive construct plays in ED treatment. This study investigated whether: (1) interventions principally designed to target ED psychopathology also lead to improvements in positive body image indices (i.e., body appreciation, functionality appreciation, and body image flexibility); (2) changes in ED symptoms correlate with changes in positive body image, both concurrently and prospectively; and (3) baseline positive body image levels moderate the degree of symptom improvement. Secondary analyses from a randomized controlled trial on digital interventions for EDs (n=600) were conducted. Intervention participants reported greater increases in the three positive body image constructs than the control group (ds=0.15-0.41). Greater pre-post reductions in ED psychopathology and binge eating were associated with greater pre-post improvements in positive body image indices. However, earlier reductions in ED psychopathology and binge eating did not predict later improvements in positive body image at follow-up. None of the positive body image constructs at baseline moderated degree of symptom change. Standard ED interventions can cultivate a more positive body image, although this is not explained by earlier symptom reduction. Understanding the mechanisms through which ED interventions enhance positive body image is needed.

Abstract
Relapse is a substantial problem in eating disorders. Until recently, there have been few investigations into maintenance treatments aimed at helping patients maintain improvements made in treatment. This study compared the outcomes of group-based intensive outpatient versus individual cognitive behavioural therapy (CBT)-based maintenance treatments for eating disorders, following inpatient or day treatment. In this sequential cohort study, patients received the type of maintenance treatment (intensive outpatient group or individual CBT) available at the time. A total of 221 patients with eating disorders were included, and data were examined retrospectively. Cox regression was used to determine whether treatment type predicted rate of return to clinically significant symptoms over the 12 months following inpatient or day treatment. Intensive outpatient group versus individual CBT maintenance treatment did not predict differential rate or trajectory of return to clinically significant symptoms in diagnostic subgroups and the overall sample. Maintenance treatment type did not predict changes in weight/shape concerns between end-of-inpatient or day treatment) and 6- or 12-month follow-up (after controlling for diagnosis). Although the treatments appeared similarly effective in helping patients maintain gains made in intensive treatment, individual CBT may be a more time- and cost-efficient approach to delivering maintenance treatment.

Abstract
The efficacy of individual cognitive-behavioural therapy (CBT) for eating disorders can be assessed by investigating the potential predictors, mediators and moderators of treatment. The present review focused on personality since its crucial role has been emphasized both by research and practice. Sixteen studies were collected, and data were extracted through a highly operationalized coding system. Overall, personality disorders were the most investigated construct; however, their influence was somewhat contradictory. A more cogent result occurred for borderline personality disorder (BPD) when considered as a moderator (not a predictor nor a mediator). Patients with a more disturbed borderline personality benefited to a greater extent from treatments including booster modules on affects, interpersonal relationships and mood intolerance, rather than symptoms exclusively. Nine additional personality dimensions, beyond BPD, were investigated sparsely, and results regarding them were barely indicative in this review. However, some of these dimensions (e.g., affective lability and stimulus-seeking behaviours) could be traced back to BPD, thereby strengthening evidence of the role of borderline disorder as a moderator. Although research on the relationship between personality and eating disorders needs to be increased and methodologically improved, personality, taken as a whole, emerged as a promising variable for enhancing the efficacy of CBT.

Abstract
OBJECTIVE Although studies with short and intermediate observation time suggest favorable outcomes in regard to eating disorders (ED), there is limited knowledge on long-term outcomes. The present study aimed to investigate the 5- and 17-year outcome of adult patients with longstanding ED who were previously admitted to an inpatient ED unit. ED diagnoses and recovery, comorbid and general psychopathology, along with psychosocial functioning and quality of life were evaluated. METHOD Sixty-two of the 80 living patients (78% response rate) with anorexia nervosa (n = 23), bulimia nervosa (n = 25), or other specified feeding or eating disorders (n = 14) at admission were evaluated. The mean age at the 17-year follow-up point was 46.2 (SD 7.5). The Eating Disorder Examination (EDE) was used to assess recovery. The Mini International Neuropsychiatric Interview (M.I.N.I.) and self-report instruments provided additional information. RESULTS There was a significant reduction in patients fulfilling criteria for an ED from the 5-year to the 17-year follow-up, meanwhile recovery rates were stable. A total of 29% of the patients were fully recovered and 21% were partially recovered while the remaining 50% had not recovered. No significant changes were found in any self-report measures and more than 70% had a comorbid disorder at both assessments. DISCUSSION The findings illustrate the protracted nature of ED for adults with longstanding ED. A long illness duration prior to treatment is unfortunate and early detection and treatment is advisable.

BACKGROUND Patients with eating disorders may experience a severe and enduring course of illness. Treatment outcome for patients provided with inpatient treatment is reported as poor. Research to date has not provided consistent results for predictors of treatment outcome. The aims of the study were to investigate rates of remission at follow-up after inpatient treatment, symptom change from admission to follow-up, and predictors of treatment outcome. METHODS The follow-up sample consisted of 150 female adult former patients (69.4% of all eligible female patients) with eating disorders. Mean age at admission was 21.7 (SD = 4.9) years. Diagnostic distribution: 66% (n = 99) anorexia nervosa, 21.3% (n = 32) bulimia nervosa and 12.7% (n = 19) other specified feeding or eating disorder, including binge eating. Data were collected at admission, discharge and follow-up (mean 2.7 (SD = 1.9) years). Definition of remission was based on the EDE-Q Global score, body mass index and binge/purge behavior. Paired T-tests were performed to investigate change over time. Univariate and multivariate logistic regressions were estimated to investigate predictors of remission. RESULTS At follow-up, 35.2% of the participants were classified as in remission. Significant symptom reduction (in all patients) (p < 0.001) and significant increase in body mass index (BMI) (in underweight participants at admission) (p < 0.001) was found. Increased BMI (p < 0.05), the level of core eating disorder symptoms at admission (p < 0.01) and reduced core eating disorder symptoms (p < 0.01) during inpatient treatment were found significant predictors of outcome in the multivariate model. CONCLUSIONS All participants had an eating disorder requiring inpatient treatment. Approximately one-third of all participants could be classified as in remission at follow-up. However, most participants experienced significant symptom improvement during inpatient treatment and the improvements were sustained at follow-up. Increased probability of remission at follow-up was indicated by lower core ED symptoms at admission for all patients, raised BMI during admission for patients with AN, and reduced core ED symptoms during inpatient treatment for all patients. This finding contributes important information and highlights the importance of targeting these core symptoms in transdiagnostic treatment programs.

Abstract
OBJECTIVE The current research investigated whether a consensus among professional eating disorder researchers existed for definitions of remission and recovery that could be used in research. METHOD Membership of the Eating Disorder Research Society and attendees at the 2018 annual meeting in Sydney were invited to participate in this investigation. Two surveys were conducted with 62 and 122 respondents, respectively. The first survey used a mix of forced choice yes/no or scaled responses. The second survey was a free response to the question "which definitions of recovery do you favor?" RESULTS A majority consensus emerged about three issues. First, it was agreed that it was important to develop a standard definition of recovery for research purposes. Second, recovery needed to be evident over a 12-month period, with remission evident over a 3- to 12-month period. Third, recovery and remission required the absence of diagnostic criteria in addition to the presence of functional recovery. DISCUSSION Consensus is apparent in the field. We suggest that future research seeks to: (a) validate the most commonly researched definition of remission and recovery across different eating disorders using a standardized battery of assessments, and (b) better understand differences in self-assessed and psychometrically assessed recovery.

Abstract
OBJECTIVE The present meta-analysis evaluated changes in individuals' risk of engaging in distinct disordered eating behaviors (DEBs) in the long-term. METHOD Longitudinal studies assessing changes in DEBs via ≥2 assessments with a time lag of ≥10 years were included. Risk ratios were calculated for baseline to 10-14.9-year (M = 11.04) follow-up and baseline to ≥15-year (M = 18.62) follow-up changes in the use of binge eating, multiple purging, self-induced vomiting, laxatives, diuretics, diet pills, compensatory exercising, fasting/dieting, and multiple DEBs; Cohen's d was used for continuous binge-eating plus purging variable changes. Subgroup and meta-regression analyses tested whether eating disorder (ED) clinical sample versus nonclinical sample status, female versus male sex/gender, higher versus lower study bias, and baseline mean age and body mass index influenced overall effect magnitude for analyses with sufficient data. RESULTS Seventeen studies (26 [sub]samples) were included. Overall, individuals' risk of engaging in various restrictive eating and other compensatory behaviors decreased over time and the magnitudes of risk reductions for the use of certain compensatory DEBs were larger over longer follow-up durations. Specifically, for significant DEB change models, risk reductions spanned from 20.0-39.8% for 10-year follow-up and 24.7-74.8% for ≥15-year follow-up. However, nuances were found in the nature of these DEB changes as a function of DEB type, follow-up length, ED versus nonclinical sample composition, and baseline mean age. CONCLUSIONS These findings provide important information that can help identify treatment priorities and suggest that targeted and tailored preventative ED treatments warrant consistent implementation at the community-level, particularly for youth.

Meta-analysis of the effects of cognitive-behavioral therapy for binge-eating-type disorders on abstinence rates in nonrandomized effectiveness studies: Comparable outcomes to randomized, controlled trials? Int J Eat Disord 2018; 51:1303-1311.

Abstract
OBJECTIVE The efficacy of cognitive-behavioral therapy (CBT) for eating disorders is well-established. The extent to which CBT tested in controlled research settings generalizes to real-world circumstances is unknown. We conducted a meta-analysis of nonrandomized studies of CBT for eating disorders, with three aims: (a) to estimate the prevalence of patients who achieve binge-purge abstinence after CBT in routine practice; (b) to compare these estimates with those derived from two recent meta-analyses of randomized controlled trials (RCTs) of CBT for bulimia nervosa (BN) and binge-eating disorder (BED); (c) to examine whether the degree of clinical representativeness of studies was associated with effect sizes. METHOD Twenty-seven studies, mainly involving BN, were included. Pooled event rates were calculated using random effects models. RESULTS The percentage of treatment completers who achieved abstinence at post-treatment was 42.1% (95% CI = 34.7-50.0). The intention-to-treat (ITT) estimate was lower (34.6% [95% CI = 29.3-40.4]). However, abstinence rates varied across diagnoses, such that the completer and ITT analysis abstinence estimates were larger for BED samples (completer = 50.2%, 95% CI = 29.4-70.9; ITT = 47.2%, 95% CI = 29.8-65.2) than for BN (completer = 37.4%, 95% CI = 29.1-46.5; ITT = 29.8%, 95% CI = 24.9-35.3) and atypical eating disorder samples (completer = 37.8%, 95% CI = 20.2-59.3; ITT = 28.8%, 95% CI = 18.2-42.4). No relationship between the degree of clinical representativeness and the effect size was observed, and our estimates were highly comparable to those observed in recent meta-analyses of RCTs. DISCUSSION Findings suggest that CBT for eating disorder can be effectively delivered in real-world settings. This study provides evidence for the generalizability of CBT from controlled research settings to routine clinical services.

Abstract
PURPOSE OF REVIEW This review delineates issues in the conceptualization and operationalization of eating disorder recovery, highlights recent findings about recovery (since 2016), and proposes future directions. RECENT FINDINGS A longstanding problem in the field is that there are almost as many different definitions of recovery in eating disorders as there are studies on the topic. Yet, there has been a general shift to accepting that psychological/cognitive symptoms are important to recovery in addition to physical and behavioral indices. Further, several operationalizations of recovery have been proposed over the past two decades, and some efforts to validate operationalizations exist. However, this work has had limited impact and uptake, such that the field is suffering from "broken record syndrome," where calls are made for universal definitions time and time again. It is critical that proposed operationalizations be compared empirically to help arrive at a consensus definition and that institutional/organizational support help facilitate this. Themes in recent recovery research include identifying predictors, examining biological/neuropsychological factors, and considering severe and enduring anorexia nervosa. From qualitative research, those who have experienced eating disorders highlight recovery as a journey, as well as factors such as hope, self-acceptance, and benefiting from support from others as integral to the process of recovery. The field urgently needs to implement a universal definition of recovery that is backed by evidence, that can parsimoniously be implemented in clinical practice, and that will lead to greater harmonization of scientific findings.

Abstract
OBJECTIVE Standardized effect sizes reported in previous meta-analyses of binge-eating disorder (BED) treatment are sometimes difficult to interpret and are criticized for not being a useful indicator of the clinical importance of a treatment. Abstinence from binge eating is a clinically relevant component of a definition of a successful treatment outcome. This meta-analysis estimated the prevalence of patients with BED who achieved binge eating abstinence following psychological or behavioral treatments. METHOD This meta-analysis included 39 randomized controlled trials, with 65 treatment conditions and 2,349 patients. Most conditions comprised cognitive-behavioral therapy (n = 40). Pooled event rates were calculated at posttreatment and follow-up using random effects models. RESULTS The total weighted percentage of treatment-completers who achieved abstinence at posttreatment was 50.9% (95% CI = 43.9, 57.8); this estimate was almost identical at follow-up (50.3%; 95% CI = 43.6, 56.9). The total weighted percentage of patients who achieved abstinence at posttreatment in the intention-to-treat analysis (all randomized patients) was 45.1% (95% CI =40.7, 49.5), and at follow-up it was 42.3% (95% CI =37.5, 47.2). Interpersonal psychotherapy (IPT) produced the highest abstinence rates. Clinician-led group treatments produced significantly higher posttreatment (but not follow-up) abstinence estimates than guided self-help treatments. Neither timeframe for achieving abstinence, assessment type (interview/questionnaire), number of treatment sessions, patient demographics, nor trial quality, moderated the abstinence estimates. DISCUSSION The present findings demonstrate that 50% of patients with BED do not fully respond to treatment. Continued efforts toward improving eating disorder treatments are needed.

Abstract
BACKGROUND While randomized controlled trials (RCTs) inform the efficacy and effectiveness of treatments, we need to understand that even RCTs can be associated with sub-optimal execution. This is of special pertinence to eating disorders given the majority of treatment studies involving cognitive behaviour therapy are of poor quality with respect to managing risk of bias adequately. METHODS The current paper outlines the components of a good RCT for psychotherapy, and examines ways to improve the conduct, interpretation, and usefulness of RCTs. RESULTS This includes managing reporting bias, recognizing the limits of randomization, applicability, and ethical considerations. CONCLUSIONS We highlight a number of strategies for future research, including issues related to utilizing a variety of designs to examine treatment outcomes, integrity, openness and reproducibility.

Abstract
OBJECTIVES It is unclear how many patients with bulimia nervosa (BN) completely abstain from the core behavioral symptoms after receiving psychological treatment. The present meta-analysis of randomized controlled trials (RCTs) aimed to (a) estimate the prevalence of patients who abstain from binge eating and/or purging following all psychological treatments for BN, and (b) test whether these abstinence estimates are moderated by the type of treatment modality delivered, the definition of abstinence applied, and trial quality. METHOD Forty-five RCTs were included, with 78 psychotherapy conditions. Pooled event rates were calculated using random effects models. RESULTS At post-treatment, the total weighted percentage of treatment-completers who achieved abstinence was 35.4% (95% CI = 29.6, 41.7), while the total weighted percentage of abstinence for all randomized patients (intention-to-treat) was 29.9% (95% CI = 25.7, 33.2). Abstinence estimates were highest in trials that used behavioral-based treatments (e.g., cognitive-behavioral therapy, behavior therapy). There was also evidence that guided self-help interventions produced the lowest post-treatment abstinence rates, but with no difference at follow-up from clinician-led treatments, and studies that used a shorter timeframe for defining abstinence (i.e., 14 days symptom-free compared to 28-days symptom-free) produced the highest abstinence rates. Abstinence estimates at follow-up for both the completer (34.6%; 95% CI = 29.3, 40.2) and intention-to-treat (28.6%; 95% CI = 25.1, 32.3) analyses were essentially the same as the post-treatment estimates. DISCUSSION Over 60% of patients fail to fully abstain from core BN symptoms even after receiving our most empirically-supported treatments. The present findings highlight the urgency toward improving the effectiveness of psychological treatments for BN.

Abstract
OBJECTIVE The objective of this study was to investigate predictors of long-term recovery from eating disorders 22 years after entry into a longitudinal study. METHOD One hundred and seventy-six of the 228 surviving participants (77.2%) were re-interviewed 20-25 years after study entry using the Longitudinal Interval Follow-up Evaluation to assess ED recovery. The sample consisted of 100 women diagnosed with anorexia nervosa (AN) and 76 with bulimia nervosa (BN) at study entry. RESULTS A comorbid diagnosis of major depression at the start of the study strongly predicted having a diagnosis of AN-Restricting type at the 22-year assessment. A higher body mass index (BMI) at study intake decreased the odds of being diagnosed with AN-Binge Purge type, relative to being recovered, 22 years later. The only predictor that increased the likelihood of having a diagnosis of BN at the 22-year assessment was the length of time during the study when the diagnostic criteria for BN were met. CONCLUSIONS Together, these results indicate that the presence and persistence of binge eating and purging behaviors were poor prognostic indicators and that comorbidity with depression is particularly pernicious in AN. Treatment providers might pay particular attention to these issues in an effort to positively influence recovery over the long-term.

Abstract
OBJECTIVE This study was to model the cost-effectiveness of specialist-delivered cognitive behavioral therapy for bulimia nervosa (CBT-BN) compared to no intervention within the Australian context. METHOD An illness-death model was developed to estimate the cost per disability-adjusted life-year (DALY) averted of CBT-BN over 2 years from the healthcare perspective. Target population was adults aged 18-65 years with BN. Results are reported as incremental cost-effectiveness ratios (ICER) in 2013 Australian dollars per DALY averted. Uncertainty and sensitivity analyses were conducted to test the robustness of results. RESULTS Primary analysis indicated that CBT-BN was associated with greater DALY averted (0.10 DALY per person) and higher costs ($1,435 per person) than no intervention, resulting the mean ICER of $14,451 per DALY averted (95% uncertainty interval [UI]: $8,762 to $35,650). Uncertainty analysis indicated CBT-BN is 99% likely to be cost-effective at a threshold of $50,000 per DALY averted. Including the patients' time and travel costs resulted in the mean ICER of $18,858 per DALY averted (95% UI: $11,235 to $46,026). Sensitivity analysis indicated the intervention was not cost-effective if over 80% people discontinued treatment. Other analyses including a reduced time horizon, increased remission rates, and 4-month effect size of CBT-BN increases the ICERs but these ICERs remained well below under a threshold of $50,000 per DALY averted. CONCLUSION This study has demonstrated that CBT-BN for adults with BN is a cost-effective treatment intervention. Further research is required to investigate the practicability of CBT-ED and the cost-effectiveness of other formats of CBT-BN delivery.

Abstract
PURPOSE The aim was to examine duration of illness and body mass index as possible moderators of the relationship between eating disorder severity and functional impairment, as well as psychological distress as a possible mediator of this relationship. METHODS The study included 159 patients diagnosed with bulimia nervosa, binge eating disorder or eating disorder not otherwise specified. Regression analysis was applied to assess the effect of the hypothesized moderators and mediators. Eating disorder severity was measured with the Eating Disorder Examination Questionnaire, functional impairment was measured with the Sheehan Disability Scale, and psychological distress was measured with the Symptom Check List-90-R. Duration of illness and body mass index were assessed clinically. RESULTS Duration of illness significantly moderated the relationship between eating disorder severity and functional impairment; the relationship was strongest for patients with a shorter duration of illness. Psychological distress partly mediated the relationship between eating disorder severity and functional impairment. Duration of illness significantly moderated the relationship between psychological distress and functional impairment; the strongest relationship was seen for patients with a shorter duration of illness. Body mass index was not a significant moderator of the relationship between ED severity and functional impairment. CONCLUSIONS Overall, this study established a link between ED severity, psychological distress and functional impairment indicating that both eating disorder severity and psychological distress are more strongly related to impaired role functioning for patients with more recent onset of an eating disorder. More research in the complex relationship between ED severity and functional impairment is needed.

Abstract
OBJECTIVE Meta-analyses have documented the efficacy of cognitive-behavioral therapy (CBT) for reducing symptoms of eating disorders. However, it is not known whether CBT for eating disorders can also improve quality of life (QoL). This meta-analysis therefore examined the effects of CBT for eating disorders on subjective QoL and health-related quality of life (QoL). METHOD Studies that assessed QoL before and after CBT for eating disorders were searched in the PsycInfo and Medline database. Thirty-four articles met inclusion criteria. Pooled within and between-groups Hedge's g were calculated at post-treatment and follow-up for treatment changes on both subjective and HRQoL using a random effects model. RESULTS CBT led to significant and modest improvements in subjective QoL and HRQoL from pre to post-treatment and follow-up. CBT led to greater subjective QoL improvements than inactive (i.e., wait-list) and active (i.e., a combination of bona fide therapies, psychoeducation) comparisons. CBT also led to greater HRQoL improvements than inactive, but not active, comparisons. Prepost QoL improvements were larger in studies that delivered CBT individually and by a therapist or according to the cognitive maintenance model of eating disorders (CBT-BN or CBT-E); though this was not replicated at follow-up CONCLUSIONS: Findings provide preliminary evidence that CBT for eating disorders is associated with modest improvements in QOL, and that CBT may be associated with greater improvements in QOL relative to comparison conditions.

J Eat Disord 2016; 4:36. [PMID: 28018596 PMCID: PMC5159948 DOI: 10.1186/s40337-016-0114-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2016] [Accepted: 08/04/2016] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND This paper explores the differing perspectives of recovery and care of people with disordered eating. We consider the views of those who have not sought help for their disordered eating, or who have been given a diagnosis but have not engaged with health care services. Our aim is to demonstrate the importance of the cultural context of care and how this might shape people's perspectives of recovery and openness to receiving professional care. METHOD This study utilised a mixed methods approach of ethnographic fieldwork and psychological evaluation with 28 women from Adelaide, South Australia. Semi-structured interviews, observations, field notes and the Eating Disorder Examination were the primary forms of data collection. Data was analysed using thematic analysis. RESULTS & DISCUSSION Participants in our study described how their disordered eating afforded them safety and were consistent with cultural values concerning healthy eating and gendered bodies. Disordered eating was viewed as a form of self-care, in which people protect and 'take care' of themselves. These subjectively experienced understandings of care underlie eating disorder behaviours and provide an obstacle in seeking any form of treatment that might lead to recovery. CONCLUSION A shared understanding between patients and health professionals about the function of the eating disorder may avoid conflict and provide a pathway to treatment. These results suggest the construction of care by patients should not be taken for granted in therapeutic guidelines. A discussion considering how disordered eating practices are embedded in a matrix of care, health, eating and body practices may enhance the therapeutic relationship.

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
OBJECTIVE Understanding the factors that predict a favourable outcome following specialist treatment for an eating disorder may assist in improving treatment efficacy, and in developing novel interventions. This review and meta-analysis examined predictors of treatment outcome and drop-out. METHOD A literature search was conducted to identify research investigating predictors of outcome in individuals treated for an eating disorder. We organized predictors first by statistical type (simple, meditational, and moderational), and then by category. Average weighted mean effect sizes (r) were calculated for each category of predictor. RESULTS The most robust predictor of outcome at both end of treatment (EoT) and follow-up was the meditational mechanism of greater symptom change early during treatment. Simple baseline predictors associated with better outcomes at both EoT and follow-up included higher BMI, fewer binge/purge behaviors, greater motivation to recover, lower depression, lower shape/weight concern, fewer comorbidities, better interpersonal functioning and fewer familial problems. Drop-out was predicted by more binge/purge behaviors and lower motivation to recover. For most predictors, there was large interstudy variability in effect sizes, and outcomes were operationalized in different ways. There were generally insufficient studies to allow analysis of predictors by eating disorder subtype or treatment type. DISCUSSION To ensure that this area continues to develop with robust and clinically relevant findings, future studies should adopt a consistent definition of outcome and continue to examine complex multivariate predictor models. Growth in this area will allow for stronger conclusions to be drawn about the prediction of outcome for specific diagnoses and treatment types.

Abstract
The fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) resulted in substantial changes with regard to the classification of Eating Disorders. In DSM-5, Feeding and Eating Disorders are for the first time subsumed in a single category. The Binge Eating Disorder (BED) was established as the third classical eating disorder in addition to Anorexia Nervosa (AN) and Bulimia Nervosa (BN). The criteria for AN changed remarkably, whereas there were only minor changes to the BN criteria. The criteria for BED differ only marginally from the DSM-IV research criteria. There are now subtypes of AN, BN, and BED in the new category "Other Specific Feeding and Eating Disorders." The rest category "Eating Disorders Not Otherwise Specified" has been renamed to "Unspecified Feeding or Eating Disorders." The practicability of the DSM-5 criteria for Eating Disorders, and for AN in particular, for both clinical practice and research remains to be seen.

Abstract
BACKGROUND Previous studies have predominantly evaluated the effectiveness of inpatient treatment for anorexia nervosa at the group level. The aim of this study was to evaluate treatment outcomes at an individual level based on the clinical significance of improvement. Patients' treatment outcomes were classified into four groups: deteriorated, unchanged, reliably improved and clinically significantly improved. Furthermore, the study set out to explore predictors of clinically significant changes in eating disorder psychopathology. METHODS A total of 435 inpatients were assessed at admission and at discharge on the following measures: body-mass-index, eating disorder symptoms, general psychopathology, depression and motivation for change. RESULTS 20.0-32.0% of patients showed reliable changes and 34.1-55.3% showed clinically significant changes in the various outcome measures. Between 23.0% and 34.5% remained unchanged and between 1.7% and 3.0% deteriorated. Motivation for change and depressive symptoms were identified as positive predictors of clinically significant changes in eating disorder psychopathology, whereas body dissatisfaction, impulse regulation, social insecurity and education were negative predictors. CONCLUSIONS Despite high rates of reliable and clinically significant changes following intensive inpatient treatment, about one third of anorexia nervosa patients showed no significant response to treatment. Future studies should focus on the identification of non-responders as well as on the development of treatment strategies for these patients.

Abstract
OBJECTIVE For eating disorders, a vast number of investigations have demonstrated the efficacy of psychological treatments. However, evidence supporting the impact of therapeutic process aspects on outcome (i.e., process-outcome research) has not been disentangled. METHOD Using the Generic Model of Psychotherapy (GMP) to organize various process aspects, a systematic literature search was conducted on psychological treatment studies for anorexia nervosa, bulimia nervosa, binge-eating disorder, and eating disorders not otherwise specified. RESULTS Improved outcomes resulted for family-based treatment compared to individual treatment, for individual compared to group treatment, booster sessions, and positive patient expectations (GMP contract aspect); for nutritional counseling and exercising but not exposure with response prevention as adjunct interventions (therapeutic operations); for highly motivated patients and, to a lesser extent, for therapeutic alliance (therapeutic bond); as well as for rapid response and longer overall treatment duration (temporal patterns). Regarding other GMP aspects, studies on self-relatedness were completely lacking and in-session impacts were rarely investigated. DISCUSSION As most studies assessed only a limited number of process aspects, the ability to draw conclusions about their overall impact regarding outcome is rather limited. Therefore, future process-outcome research is needed beyond investigations of treatment efficacy for eating disorders.

Investigating applications of various remission definitions and their associations with quality of life. J Psychosom Res 2014; 76:12-8.

Abstract
OBJECTIVE To compare remission rates, determine level of agreement and identify quality of life (QoL) distinctions across a broad spectrum of remission definitions among patients with eating disorders (ED). METHODS Women (N=195; 94 AN, 24 BN, and 77 EDNOS) from inpatient and partial hospital ED programs participated in a study of treatment outcomes. Remission rates were evaluated with percentages, kappa coefficients identified level of agreement and Mann-Whitney-Wilcoxon tests with Bonferroni corrections determined differences in quality of life between remitted and not remitted patients by remission definition. RESULTS Depending on remission definition used, the percent of remitted patients varied from 13.2% to 40.5% for AN, 15.0% to 47.6% for BN and 24.2% to 53.1% for EDNOS. Several definitions demonstrated "very good" agreement across diagnoses. Remission was associated with higher quality of life in psychological, physical/cognitive, financial and work/school domains on a disease-specific measure, and in mental but not physical functioning on a generic measure. CONCLUSIONS Remission rates vary widely depending on the definition used; several definitions show strong agreement. Remission is associated with quality of life, and often approximates scores for women who do not have an eating disorder. The ED field would benefit from adopting uniform criteria, which would allow for more accurate comparison of remission rates across therapeutic interventions, treatment modalities and facilities. We recommend using the Bardone-Cone criteria because it includes assessment of psychological functioning, was found to be applicable across diagnoses, demonstrated good agreement, and was able to distinguish quality of life differences between remitted and not remitted patients.

Abstract
BACKGROUND Eating Disorders (EDs) are complex psychiatric pathologies characterized by moderate to poor response to treatment. Criteria of remission and recovery are not yet well defined. Simultaneously, personality plays a key role among the factors that determine treatment outcome. The aim of the present research is to evaluate the possibility of temperamental and character traits to predict the long-term outcome of ED. METHOD A sample of 25 AN and 28 BN female patients were re-assessed face-to-face after a minimum 5-years-follow-up through SCID-I, EDI-2 and TCI-R. Regression Analyses were performed to ascertain the possibility of TCI-R dimensions at the first visit to predict the long-term outcome. RESULTS Clinical and psychopathological symptoms significantly decreased over the time and 23% of participants no longer received a categorical ED diagnosis after at least 5 years of follow-up. TCI-R dimensions failed to predict the absence of a DSM-IV-TR diagnosis in the long term, but Novelty Seeking, Harm Avoidance and Reward Dependence demonstrated to predict the clinical improvement of several EDI-2 scales. CONCLUSIONS Our results support the idea that temperamental dimensions are relevant to the long-term improvement of clinical variables of ED. Low Novelty Seeking is the strongest predictor of poor outcome.
