Abstract
BACKGROUND Psychiatric disorders, including eating disorders (EDs), have clinical outcomes that range widely in severity and chronicity. The ability to predict such outcomes is extremely limited. Machine-learning (ML) approaches that model complexity may optimize the prediction of multifaceted psychiatric behaviors. However, the investigations of many psychiatric concerns have not capitalized on ML to improve prognosis. This study conducted the first comparison of an ML approach (elastic net regularized logistic regression) to traditional regression to longitudinally predict ED outcomes. METHODS Females with heterogeneous ED diagnoses completed demographic and psychiatric assessments at baseline (n = 415) and Year 1 (n = 320) and 2 (n = 277) follow-ups. Elastic net and traditional logistic regression models comprising the same baseline variables were compared in ability to longitudinally predict ED diagnosis, binge eating, compensatory behavior, and underweight BMI at Years 1 and 2. RESULTS Elastic net models had higher accuracy for all outcomes at Years 1 and 2 [average Area Under the Receiving Operating Characteristics Curve (AUC) = 0.78] compared to logistic regression (average AUC = 0.67). Model performance did not deteriorate when the most important predictor was removed or an alternative ML algorithm (random forests) was applied. Baseline ED (e.g. diagnosis), psychiatric (e.g. hospitalization), and demographic (e.g. ethnicity) characteristics emerged as important predictors in exploratory predictor importance analyses. CONCLUSIONS ML algorithms can enhance the prediction of ED symptoms for 2 years and may identify important risk markers. The superior accuracy of ML for predicting complex outcomes suggests that these approaches may ultimately aid in advancing precision medicine for serious psychiatric disorders.

Detection, treatment, and course of eating disorders in Finland: A population-based study of adolescent and young adult females and males. EUROPEAN EATING DISORDERS REVIEW 2021; 29:720-732. [PMID: 34008267 PMCID: PMC8349843 DOI: 10.1002/erv.2838] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 03/22/2021] [Accepted: 04/26/2021] [Indexed: 11/17/2022]
Abstract
Objective: We assessed the detection, treatment and outcomes of DSM-5 eating disorders in a nationwide community setting. Method: The FinnTwin12 cohort comprises twins born in 1983–1987 in Finland (n = 5,600), with follow-up starting at age 12. We outline treatment and outcomes of the 127 females and 15 males diagnosed with a lifetime DSM-5 eating disorder in interviews conducted for a subsample (n = 1,347) in their early 20s. Results: Only 45 (32%) of those diagnosed with eating disorder in the interviews had their condition detected in healthcare, and even fewer received treatment (30% of females, 13% of males). Anorexia nervosa (AN), bulimia nervosa, and atypical AN were detected and treated more often than other eating disorders. Five years after disease onset, 41% of those diagnosed had recovered. There were no statistically significant differences in the course of different eating disorders (log-rank p = 0.66) but the outcome was more favourable among males (log-rank p = 0.008). The likelihood of 5-year recovery did not differ between those who had and who had not received treatment (41.1% vs. 40.5%, log-rank p = 0.66). Conclusion: Although eating disorders are common and symptoms are persistent for many, they remain under-diagnosed and under-treated. In real-world settings, effectiveness of provided treatments may be limited.

Abstract
There is a critical need to identify processes that may influence outcome in existing treatments for eating disorders (EDs). Intolerance of uncertainty (IU), which refers to excessive distress regarding uncertain situations, is a well-established feature of anxiety disorders. Emerging work suggests that IU decreases over the course of cognitive-behavioral treatments and may relate to better treatment outcomes. As some literature has suggested IU may functionally maintain ED symptoms, testing whether changes in IU over treatment relate to outcome may result in the identification of novel treatment targets. This study aimed to build upon past work documenting links between IU and ED symptoms by exploring changes in IU over treatment and links between early change in IU (1-month) and discharge symptoms. Participants (N = 274) receiving partial hospitalization treatment completed the Eating Pathology Symptoms Inventory and Intolerance of Uncertainty Scale at admission, 1-month post-admission, and discharge. Results suggested that IU significantly reduced from admission to discharge and that reductions in IU scores from admission to 1-month related to cognitive restraint, dietary restriction, and body image at discharge. However, this pattern did not hold for exercise, binge eating, or purging. Altogether, these results replicate past work supporting IU as a common feature across ED diagnoses and provide initial data suggesting that targeting IU early in treatment may enhance treatment outcomes.

Abstract
PURPOSE Although personality has been widely researched in patients with anorexia nervosa (AN) and bulimia nervosa (BN), the nature of this relationship has not yet been clearly articulated. The pathoplasty model theorizes that personality might shape symptomatic presentation and thus affect therapeutic outcomes, but more research is needed. The present study aimed at investigating the predictive value of a broad spectrum of personality traits in determining AN and BN treatment outcomes, considering both the statistical and clinical significance of the therapeutic change. METHODS Eighty-four female patients with AN and BN treated in a residential program were evaluated at treatment onset using the Shedler-Westen Assessment Procedure-200-a clinician-rated measure of personality disorders and healthy personality functioning. At both intake and discharge, patients completed the Eating Disorder Inventory-3 to assess eating symptoms and the Outcome Questionnaire-45.2 to evaluate overall impairment. RESULTS Considering overall ED symptomatic change, multiple regression analyses showed that, even when controlling for baseline symptoms and DSM-5 categories, schizoid (B = 0.41, p ≤ 0.01), avoidant (B = 0.31, p ≤ 0.05), and paranoid (B = 0.25, p ≤ 0.05) personality features predicted worse therapeutic outcomes. Similar results were found when applying the clinical significance approach, with the emotionally dysregulated factor as an additional negative predictor of significant/reliable change (B = - 0.09; p < 0.01). Healthy personality functioning predicted better therapeutic outcomes (B = - 0.34, p ≤ 0.001). CONCLUSIONS Pathoplastic models and personality-based research in this clinical population have the potential to inform effective treatment strategies by targeting relevant individual factors.

Abstract
OBJECTIVE Predictive values of acute phase metabolic abnormalities of anorexia nervosa (AN) have seldom been studied. As early postrestoration weight loss is associated with poor outcome, discharge biologic parameters were assessed to detect an association with 2-month follow-up weight loss as a proxy to poor outcome. METHOD Fasting plasma levels of leptin, acyl-ghrelin, obestatin, PYY, oxytocin and BDNF were measured in 26 inpatients, at inclusion, at discharge and 2 months later. A body mass index less than 18 2-month postdischarge was considered a poor outcome. RESULTS Nineteen patients (73%) had a fair outcome and seven (27%) had a poor one with a mean loss of 0.69 versus 4.54 kg, respectively. Only discharge leptin levels were significantly higher in fair versus poor outcome patients (14.1 vs. 7.0 ng/ml, p = 0.006). The logistic regression model using discharge leptin, acyl-ghrelin, obestatin, oxytocin, PYY and BDNF levels as predictors of outcome disclosed a nearly significant effect of leptin (p < 0.10). Receiver operating characteristic analysis showed 11.9 ng/ml was the best value of threshold. Neither clinical variables differed according to outcome. CONCLUSION Leptin level may be a biomarker of early weight relapse after acute inpatient treatment of AN. Its clinical usefulness in monitoring care in AN should further be determined.

Chang PGRY, Delgadillo J, Waller G. Early response to psychological treatment for eating disorders: A systematic review and meta-analysis. Clin Psychol Rev 2021; 86:102032. [PMID: 33915335 DOI: 10.1016/j.cpr.2021.102032] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2020] [Revised: 04/04/2021] [Accepted: 04/14/2021] [Indexed: 12/25/2022]
Abstract
Early response is a well-established predictor of positive outcomes at the end of psychological treatments for common mental disorders. There is some prior evidence that this conclusion also applies to eating disorders, including three meta-analyses, but no moderators of that relationship have been identified. However, a number of further papers have been published since, which might influence the size of the effect of early response or the potential role of moderating factors. This pre-registered systematic review presents a comprehensive examination of this literature. Three databases were searched (Scopus, PsycInfo, PubMed). In total, 33 eligible studies were included in a narrative synthesis, and 25 studies were included in random-effects meta-analysis. The majority (91%) of studies were rated as having low or moderate risk of bias. Approximately half of patients across clinical samples showed early response to psychological therapy, which was most often defined as reliable symptomatic improvement during the first four sessions. A significant and moderate association was found between early response and post-treatment outcomes (r = 0.41 [95% CI: 0.32-0.481], p < .0001). Significant evidence of heterogeneity (Q[28] = 136.42, p < .0001; I2 = 80.2%) was evident. The review was limited by the exclusion of grey literature and only 76% of studies provided sufficient statistical information for meta-analytic synthesis, although we found no significant evidence of publication bias, χ2(1) = 0.001, p = .97. Overall, evidence accumulated over twenty years establishes early response as the most robust predictor of treatment outcomes in the field of eating disorders. However, only half of patients show early change in this way. Further research is needed to determine whether there are patient or clinician characteristics that predict early response to psychological treatment for eating disorders.

Abstract
BACKGROUND Psychiatric comorbidity is common in binge-eating disorder (BED) but effects on treatment outcomes are unknown. The current study aimed to determine whether psychiatric comorbidity predicted or moderated BED treatment outcomes. METHODS In total, 636 adults with BED in randomized-controlled trials (RCTs) were assessed prior, throughout, and posttreatment by doctoral research-clinicians using reliably-administered semi-structured interviews, self-report measures, and measured weight. Data were aggregated from RCTs testing cognitive-behavioral therapy, behavioral weight loss, multi-modal (combined pharmacological plus cognitive-behavioral/behavioral), and/or control conditions. Intent-to-treat analyses (all available data) tested comorbidity (mood, anxiety, 'any disorder' separately) as predictors and moderators of outcomes. Mixed-effects models tested comorbidity effects on binge-eating frequency, global eating-disorder psychopathology, and weight. Generalized estimating equation models tested binge-eating remission (zero binge-eating episodes during the past month; missing data imputed as failure). RESULTS Overall, 41% of patients had current psychiatric comorbidity; 22% had mood and 23% had anxiety disorders. Psychiatric comorbidity did not significantly moderate the outcomes of specific treatments. Psychiatric comorbidity predicted worse eating-disorder psychopathology and higher binge-eating frequency across all treatments and timepoints. Patients with mood comorbidity were significantly less likely to remit than those without mood disorders (30% v. 41%). Psychiatric comorbidity neither predicted nor moderated weight loss. CONCLUSIONS Psychiatric comorbidity was associated with more severe BED psychopathology throughout treatment but did not moderate outcomes. Findings highlight the need to improve treatments for BED with psychiatric comorbidities but challenge perspectives that combining existing psychological and pharmacological interventions is warranted. Treatment research must identify more effective interventions for BED overall and for patients with comorbidities.

Abstract
OBJECTIVE This study aimed to assess how baseline motivation to recover impacts eating disorder (ED) and comorbid symptoms at end-of-treatment (EOT) for adolescents and adults in inpatient/residential treatment. METHOD Two hundred and three adolescent (M = 15.90) and 395 adult (M = 25.45) patients with a Diagnostic Statistical Manual, 5th edition ED diagnosis completed the Decisional Balance Scale (DBS) at baseline, and psychosocial measures (ED symptoms, anxiety, depression, obsessive-compulsive disorder symptoms), and %body mass index (kg/m2 ; BMI) or median %BMI (for adolescents) at baseline and EOT. RESULTS The DBS Avoidance Coping and Burdens subscales at baseline were significantly lower for adolescents than adults (p < 0.001), whereas the DBS Benefits subscale at baseline did not significantly differ between subsamples (p = 0.06). Motivation to recover via DBS subscales was a more reliable predictor of EOT outcomes for both ED and comorbid psychopathology in adults (significant predictor in 19 of 54 total analyses, and 4 significant associations post-Bonferroni correction) than adolescents (significant predictor in 5 of 54 total analyses, and 1 significant association post-Bonferroni correction). CONCLUSIONS Baseline motivation to recover may be an important predictor of outcome for adult patients in inpatient/residential treatment but does not appear associated with outcomes for adolescent patients.

Abstract
OBJECTIVE To assess the ability of psychotherapists to predict the future outcome for inpatients with anorexia nervosa (AN) and bulimia nervosa (BN). METHOD Psychotherapists rated the prognosis of the patient's eating disorder on a five point Likert scale on several dimensions at the end of inpatient treatment. Actual outcome was assessed about 10 years after treatment. The sample comprised 1,065 patients treated for AN, and 1,192 patients treated for BN. RESULTS Psychotherapists' rating of their patient's prognosis was not better than chance for good outcome in AN and BN and for poor outcome in BN. Prediction of poor outcome in AN was somewhat better with approximately two thirds of correct predictions. In logistic regression analysis, psychotherapists' rating of the patients' prognosis for AN contributed to the explained variance of long-term outcome, increasing the variance explained from 7% (by conventional predictors) to 8% after including psychotherapists' prognosis. In BN, there was no significant contribution of psychotherapists' prognosis to overall prediction. DISCUSSION Our current knowledge of risk and protective factors for the course of eating disorders is unsatisfying. More specialized research is urgently needed.

Abstract
OBJECTIVE Despite evidence supporting the use of measures to track ongoing progress and outcome in treatment, there is a relative absence of measures that are appropriate for this purpose in youth with eating disorders. This study examined the psychometric properties of the Eating Disorder-15 for Youth (ED-15-Y) scale, including its ability to detect short-term change in symptomatology. METHOD Youth (N = 203) ages 8-18 years completed self-report questionnaires and semi-structured diagnostic interviews upon initial presentation for an outpatient eating disorders assessment at an academic medical center. RESULTS The ED-15-Y demonstrated excellent reliability (internal consistency, split-half reliability) and high sensitivity to change early in treatment (change from sessions 1 to 8, adjusting for baseline score). Further, these data demonstrate that the ED-15-Y has excellent convergent validity, being highly correlated with a well-tested, longer measure of eating disorders psychopathology-the Eating Disorders Examination-Questionnaire (EDE-Q). These data also support good discriminant and concurrent validity, differentiating between youth without an eating disorder or with ARFID and youth with eating disorders involving weight and shape concerns (e.g., anorexia nervosa, bulimia nervosa). DISCUSSION The ED-15-Y may be a useful tool to briefly assess eating disorder psychopathology in youth as young as 8 years old. Its sensitivity to change very early in treatment suggests that it has the potential to be used as a routine outcome measure in the context of treatment.

Abstract
While eating disorders were historically considered to be a result of psychological or environmental causes, current evidence suggests that eating disorders are the product of complex gene-environment interactions wherein heritable vulnerabilities are activated by multiple exposures to environmental stimuli over the lifespan. Despite the fact that this integrated biopsychosocial etiological view of eating disorders is accepted among many professionals in the eating disorder field, evidence suggests that the general public and some clinicians are susceptible to dualist, or reductionist, views of psychopathology. Currently, little is known about (a) the prevalence of reductionist biological views of eating disorder etiology in those with eating disorders (this view attributes the cause of eating disorders to predominantly biological factors but does not acknowledge psychosocial factors as important contributors), (b) the effects of reductionist biological views on clinical outcomes, and (c) the most effective methods for modifying these views. In this article, we present the results of a preliminary investigation on the relationship between perceived causes of eating disorders and the attitudes and behaviors of those with eating disorders. We then go on to propose specific avenues for further research on uncovering the effects of reductionist biological views of eating disorder etiology.

Abstract
OBJECTIVE To explore patients' use of the self-monitoring app Recovery Record during 26 weeks of naturalistic eating disorder treatment. METHODS Selected patient characteristics at baseline were explored as predictors of app use using linear regression. Patients were grouped according to diagnosis (anorexia versus bulimia), and mixed-effects analyses were used to explore differences in app use between diagnoses across four time periods (weeks 1-4; weeks 5-8; weeks 9-12; weeks 13-26). RESULTS Eighty-four patients were included of which 41 had anorexia and 43 had bulimia. The total number of logs varied greatly (mean (SD): 592 (628.50)), and patient app activity almost ceased at week 13. Increasing age and no previous eating disorder treatment predicted increased app activity (p = .007; p = .039, respectively). Patients with anorexia logged over four times more often than patients with bulimia in the last time period (median (CI): 4.27 (1.28;14.31); p = .018). Time predicted declining app use (all p ≤ .007). CONCLUSION Future research on long-term app engagement should investigate associations between patients' app use and changes in their eating disorder symptom severity over time.

Abstract
OBJECTIVE While there is evidence to support the use of group dialectical behavior therapy (DBT) in the treatment of binge-eating disorder (BED), treatment is relatively long compared with other evidence-based treatments. This study explored the effectiveness of brief DBT groups for BED, delivered in a routine community setting. METHOD Eighty-four adults with BED entered 10-week DBT group treatment in a community eating disorders service. In total, 12 groups were conducted. Patients completed measures of eating disorder pathology, anxiety, depression, and emotional eating at the start and end of treatment, and at 1-month follow-up. Frequency of weekly binges was recorded. RESULTS Outcomes were similar to those of longer versions of DBT, with an attrition rate of 26%, and significant reductions in eating disorder psychopathology and emotional eating by the end of treatment and at follow-up. Over 50% of patients were abstinent from binge eating by Session 4. DISCUSSION Group DBT delivered in a 10-session format is clinically equivalent to longer versions of the same treatment. Future research is required to explore patterns of change and to demonstrate replicability under controlled conditions, but these findings are promising for the efficient delivery of effective treatment and reducing waiting times.

Abstract
PURPOSE The aim of the study was to assess the differences between impulsive and non-impulsive patients in response to a multidisciplinary intensive inpatient treatment for eating disorders (EDs). METHODS 320 patients with EDs were consecutively recruited in an eating disorders unit (EDU). They were assessed by clinical interviews and self-reported questionnaires. The treatment was characterized by a patient-centric approach and included both an intensive and comprehensive standardized multidisciplinary program based on cognitive-behavioral therapy and a flexible and personalized component according to the needs and the history of each patient. RESULTS Impulsive ED patients showed greater improvement in specific psychopathological areas, in particular: interpersonal sensitivity of Symptom Checklist-90 (SCL-90) (p = 0.007); Eating Disorder Examination Questionnaire (EDE-Q) Global Score (p = 0.009), EDE-Q eating concern (p < 0.001) and EDE-Q shape concern (p = 0.025). The two groups also showed a different pattern on the Body Uneasiness Test, with impulsive patients uniquely showing improvement on Global Severity Index (p = 0.006), body image concern (p = 0.008), compulsive self monitoring (p = 0.002), and weight phobia (p = 0.037). DISCUSSION Results support the hypothesis that patients with impulsive behaviors might benefit from treatments characterized by a standardized cognitive behavioral therapy implemented by third-wave interventions according to each patient's clinical profile. Personalized treatment approaches could be an answer to the complexity of ED, addressing individual psychopathology. Further studies are needed to confirm these preliminary findings. LEVEL OF EVIDENCE III, cohort or case-control analytic studies.

Abstract
BACKGROUND Data on patients with anorexia nervosa (AN) and comorbid Borderline personality disorder (AN+BPD) are scarce. Therefore, we investigated (1) whether patients with AN and AN+BPD differ in characteristics related to admission to, discharge from, and course of specialized inpatient eating disorder treatment and (2) how comorbid BPD affects treatment outcome. METHOD One-thousand one-hundred and sixty inpatients with AN (97.2% female, 5.9% with comorbid BPD; mean age = 26.15, SD = 9.41) were administered the Brief Symptom Inventory (BSI), the Eating Disorder Inventory 2 (EDI-2), and the Global Assessment of Functioning (GAF) at admission and discharge. Data were extracted by a retrospective chart review of naturalistic treatment data. Age, sex, weekly weight gain, length of stay, and discharge characteristics were compared with independent t-tests and χ2-tests. Changes in outcome variables, including body mass index (BMI), were analyzed with longitudinal multilevel mixed-effects models. RESULTS No differences in age or sex were found between patients with AN and AN+BPD, but groups differed in previous inpatient treatments, BMI at admission, and frequency of at least one additional comorbidity with higher values for AN+BPD. Higher levels of disorder-specific and general psychopathology at admission were found for AN+BPD. Patients with AN showed statistically significant improvement in all examined variables, patients with AN+BPD improved in all variables except EDI-2 body dissatisfaction. Strongest improvements in patients with AN+BPD occurred in BMI (Cohen's d = 1.08), EDI-2 total score (Cohen's d = 0.99), EDI-2 interpersonal distrust (d = 0.84). Significant Group x Time Interactions were observed for BSI GSI, GAF, and EDI-2 body dissatisfaction, indicating a reduced benefit from inpatient treatment in AN+BPD. At discharge, no differences were found in weekly weight gain, BMI, length of stay, or discharge characteristics (e.g., ability to work, reason for discharge), however, patients with AN+BPD were more frequently treated with medication. CONCLUSIONS Patients with AN+BPD differ from patients with AN in that they show higher general and specific eating disorder psychopathology and only partially improve under specialized inpatient treatment. In particular, aspects of emotion regulation and core AN symptoms like body dissatisfaction and perfectionism need to be even more targeted in comorbid patients.

Abstract
AIM In the short term, intensive treatment focusing on restoring weight for anorexia nervosa can remediate many symptoms. However, there is a high level of relapse after discharge. This paper examines interventions developed to bridge the transition from intensive to less intensive forms of treatment for adult anorexia nervosa. METHOD We undertook a systematic review of the literature on interventions aimed at providing transition support. The Template for Intervention Description and Replication was used to describe components of the transition interventions. Patient's drop-out rates, weight, eating disorder psychopathology and mood data were extracted at end of treatment and follow-up to describe preliminary efficacy. RESULTS Fourteen studies were selected: nine used psychological interventions delivered through face-to-face talking therapy or guided self-help, three examined the use of fluoxetine and two assessed stepped-care approaches. Transition support was delivered to patients in 11 studies, to patients and carers in two studies, and carers alone in another study. CONCLUSIONS There was a great heterogeneity in the content and structure of the transition interventions evaluated. Overall, drop-out rates were lower for psychological support than pharmacological interventions or stepped-care approaches. Changes in eating disorder outcomes and mood were small to moderate throughout for studies that included a comparison group.

Abstract
Adolescents and young adults, particularly females, are highly vulnerable to the development of anxiety disorders, depression, and eating disorders. Comorbid anxiety disorder or depression in eating disorders are associated with greater symptom severity, poorer prognosis, and burden of illness. Nonetheless, studies on what affects the relationship between anxiety, depression, and eating disorders in female at-risk samples are scarce. Using hierarchical linear modeling, the present study examined potential moderators to explain between-person differences in the association between anxiety, depression, and eating disorder-related impairment within 12- to 25-year-old females (N = 320). High impairment in anxiety/depression was associated with more severe eating disorder symptoms. Older age as well as greater impairment in mood dysregulation, self-esteem, and perfectionism were linked to more severe eating disorder symptomatology. Whereas mood dysregulation, self-esteem, and perfectionism had no statistically significant moderating effects, younger age appeared to augment the association of anxiety/depression and eating disorder symptomatology. Preventive care in particular needs to consider age-related effects as eating disorder symptoms are associated more strongly with symptoms of anxiety and depression in early adolescence.

Abstract
PURPOSE The many studies examining the relationship between anorexia nervosa (AN) and personality abnormalities have observed high comorbidity. However, no definitive studies to date have established whether there is a causal connection or whether it is a complication. The current study aimed to explore the nature of the relationship between personality disorder (PD) traits, obsessionality and perfectionism, using a study design that allows the testing of some comorbidity models. METHODS Twenty-nine women were recruited from a group of former AN patients treated during their adolescence in a specialized unit around 20 years before the time of this study. They were divided into two groups according to the current presence of eating disorder (ED) symptoms (current-ED, n = 11; recovered, n = 18). Both groups were compared to a matched control group (n = 29) regarding current PD traits, obsessive beliefs and perfectionism. RESULTS Borderline PD traits, most cluster C PD traits and overestimation of threat were more common in the current-ED group than in the control and recovered groups. Obsessive-compulsive PD traits, intolerance of uncertainty, and perfectionism were also significantly more prevalent in the current-ED group compared to controls but did not reach significance when compared to the recovered group. No significant differences were found between the recovered and control groups. CONCLUSION Our results mostly support the personality abnormalities observed as a transient effect related to the presence of ED psychopathology in patients with adolescent-onset AN.

Abstract
BACKGROUND Eating disorders (EDs) typically start during adolescence or emerging adulthood, periods of intense biopsychosocial development. FREED (First Episode Rapid Early Intervention for EDs) is a service model and care pathway providing rapid access to developmentally-informed care for emerging adults with EDs. FREED is associated with reduced duration of untreated eating disorder and improved clinical outcomes, but patients' experiences of treatment have yet to be assessed. OBJECTIVE This study aimed to assess emerging adults' experiences of receiving treatment through FREED. METHOD This study triangulated qualitative data on participants' experiences of FREED treatment from questionnaires and semi-structured interviews. Participants were 106 emerging adults (aged 16-25; illness duration < 3 yrs) (questionnaire only = 92; interview only = 6; both = 8). Data were analysed thematically. RESULTS Most participants reported psychological and behavioural changes over the course of treatment (e.g. reduction in symptoms; increased acceptance and understanding of difficulties). Participants identified five beneficial characteristics of FREED treatment: i) rapid access to treatment; ii) knowledgeable and concerned clinicians; iii) focusing on life beyond the eating disorder; iv) building a support network; v) becoming your own therapist. CONCLUSION This study provides further supports for the implementation of early intervention and developmentally-informed care for EDs. Future service model development should include efforts to increase early help-seeking.

Abstract
Abstract. Eating disorders are a major health concern and the identification of relevant risk factors is crucial for prevention. This meta-analysis aims to give insight into the relevance of low self-esteem in the development of pathological eating. Longitudinal and partial correlations were synthesized in a random-effects multilevel model. In total, 25 effect sizes were obtained from 13 primary studies. These mainly included females from late childhood to young adulthood. The results reveal a practically relevant effect of self-esteem on eating disorders ( r = −.23, ρ = −.09). This effect was significantly larger for females and for shorter time periods between measurements. Additionally, self-esteem and eating disorders are both temporally stable. It is concluded that low self-esteem acts as a universal risk factor for different eating disorders. Limitations are due to the reliance on bivariate correlations and a small number of effect sizes. The necessity of more high-quality research in this field is discussed.

Abstract
Proposed treatments for severe and enduring anorexia nervosa (SE-AN) focus on quality of life, and psychological and social functioning. By de-emphasizing weight restoration as a priority, however, premature diagnosis of SE-AN may reduce potential for recovery. The present study assessed the effect of weight restoration, illness duration, and severity on treatment outcome 6 months after discharge from an intensive, meal-based behavioral treatment program. Participants included hospitalized adult women (N = 191) with AN or underweight other specified feeding and eating disorder (OSFED). Participants were characterized as short-term (ill <7 years; n = 74) or long-term ill (ill ≥ 7 years; n = 117). Compared with short-term ill, long-term ill patients were older, had lower lifetime body mass index (BMI), more prior admissions, and exhibited greater depression and neuroticism. Long-term vs. short-term ill patients gained weight at the same rate (~2 kg/wk) and were equally likely to be weight restored by discharge (>75% reached BMI ≥ 19 kg/m2 in both groups). At 6-month follow-up (n = 99), both groups had equivalent self-reported BMI, and depression, drive for thinness, body dissatisfaction, and bulimia scores. The only predictor of BMI ≥ 19 kg/m2 at follow-up was discharge BMI. The likelihood of a BMI ≥ 19 kg/m2 at follow-up was 5-fold higher for those with discharge BMI ≥ 19 kg/m2. Few studies of long-term ill inpatients with AN have examined the impact of full weight restoration on short-term outcomes. This study supports the therapeutically optimistic stance that, regardless of illness duration, hospitalized patients with AN benefit from gaining weight to a BMI ≥ 19 kg/m2.

Danielsen M, Bjørnelv S, Weider S, Myklebust TÅ, Lundh H, Rø Ø. The outcome at follow-up after inpatient eating disorder treatment: a naturalistic study. J Eat Disord 2020; 8:67. [PMID: 33292634 PMCID: PMC7709321 DOI: 10.1186/s40337-020-00349-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 11/03/2020] [Indexed: 03/13/2023] Open
Abstract
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.

Predictors of illness course and health maintenance following inpatient treatment among patients with anorexia nervosa. J Eat Disord 2020; 8:69. [PMID: 33292619 PMCID: PMC7709230 DOI: 10.1186/s40337-020-00348-7] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 11/03/2020] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Anorexia nervosa (AN) is a life-threatening psychiatric disorder associated with significant medical and psychosocial impairment. Hospital-based behavioral treatment is an effective intervention in the short-term. However, relapse rates following discharge are high and thus, there is a need to identify predictors of longitudinal outcome. The current study provides information regarding illness course and health maintenance among patients with AN over 5 years following discharge from an eating disorder inpatient unit. METHODS Participants were individuals with AN who were discharged from a specialized, inpatient behaviorally-based unit. Prior to discharge, height and weight were measured and participants completed self-report measures of eating disorder severity and general psychopathology (depression, anxiety, harm avoidance). Participants were contacted annually for self-report measures of weight, eating disorder severity and clinical impairment. Outcome was defined by illness course (body mass index (BMI) and clinical impairment during the 5 years) and health maintenance (categories of weight and eating disorder symptom severity) across follow-up, using all available data. Linear mixed models were used to examine whether demographic and clinical parameters at discharge predicted BMI and clinical impairment over time. Additional analyses examined whether these variables significantly influenced an individual's likelihood of maintaining inpatient treatment gains. RESULTS One-hundred and sixty-eight individuals contributed data. Higher trait anxiety at discharge was associated with a lower BMI during follow-up (p = 0.012). There was a significant interaction between duration of illness and time, whereby duration of illness was associated with a faster rate of weight loss (p = 0.003) during follow-up. As duration of illness increased, there was a greater increase in self-reported clinical impairment (p = 0.011). Increased eating disorder severity at discharge was also associated with greater clinical impairment at follow-up (p = 0.004). Higher BMI at discharge was significantly associated with maintaining healthy weight across a priori BMI-based definitions of health maintenance. CONCLUSIONS Weight status (higher BMI) and duration of illness are key factors in the prognosis of AN. Higher weight targets in intensive treatments may be of value in improving outcomes.

Abstract
OBJECTIVE Identifying modifiable predictors of outcomes following treatment for eating disorders may help to tailor interventions to patients' individual needs, improve treatment efficacy, and develop new interventions. The goal of this meta-analysis was to quantify the association between pretreatment motivation and posttreatment changes in eating disorder symptomology. METHOD We reviewed 196 longitudinal studies reporting on change on indices of overall eating-disorder symptomatology, weight gain, binge-eating, vomiting, anxiety/depression, and treatment adherence. Meta-analyses were performed using two complementary approaches: (a) combined probability analysis using the added Z's method; (b) effect size analyses. Using random-effect models, effect sizes were pooled when there were at least three studies with the same type of statistical design and reporting statistics on the same outcome. Heterogeneity in study outcome was evaluated using Q and I2 statistics. Studies were reviewed qualitatively when the number of studies or reported data were insufficient to perform a meta-analysis. RESULTS Forty-two articles were included. Although samples and treatments differed substantially across studies, results across studies were remarkably consistent. Both combined-probability and effect-size analyses indicated positive effects of pretreatment motivation on improvement in general eating-disorder symptoms (Cohen's r = .17), and an absence of effects on anxiety/depression symptoms. Remaining outcome indices were subject to selective reporting and/or small sample size bias. DISCUSSION Our findings underscore the importance of incorporating treatment engagement approaches in the treatment of eating disorders. Optimal reporting of study findings and improving study quality would improve future efforts to obtain an in-depth understanding of the relationship between motivation and eating disorder symptoms.

Abstract
OBJECTIVE Binge-eating disorder (BED) is characterized by recurrent episodes of binge eating, accompanied by a lack of control and feelings of shame. Online intervention is a promising, accessible treatment approach for BED. In the current study, we compared completers with noncompleters in a 10-session guided internet-based treatment program (iBED) based on cognitive behavioral therapy. METHODS Adults (N = 75) with mild to moderate BED participated in iBED with weekly written support from psychologists. Participants were compared on the Eating Disorder Examination Questionnaire (EDE-Q), diagnostic criteria for BED (BED-Q), major depression inventory (MDI), quality of life (EQ-5D-5L), body mass index (BMI) and sociodemographic variables. RESULTS Minor differences were observed between completers and noncompleters on depression. No differences were found in BED-symptoms, BMI, and sociodemographic variables. Participants who completed treatment showed large reductions in eating disorder pathology. DISCUSSION More research is needed to determine risk factors for attrition or treatment outcome in internet-based interventions for BED. It is suggested that iBED is an efficient intervention for BED. However, more studies of internet-interventions are needed.

Abstract
INTRODUCTION Eating disorders are complex to manage, and there is limited guidance around the depth and breadth of knowledge, skills and experience required by treatment providers. The Australia & New Zealand Academy for Eating Disorders (ANZAED) convened an expert group of eating disorder researchers and clinicians to define the clinical practice and training standards recommended for mental health professionals and dietitians providing treatment for individuals with an eating disorder. General principles and clinical practice standards were first developed, after which separate mental health professional and dietitian standards were drafted and collated by the appropriate members of the expert group. The subsequent review process included four stages of consultation and document revision: (1) expert reviewers; (2) a face-to-face consultation workshop attended by approximately 100 health professionals working within the sector; (3) an extensive open access online consultation process; and (4) consultation with key professional and consumer/carer stakeholder organisations. RECOMMENDATIONS The resulting paper outlines and describes the following eight eating disorder treatment principles: (1) early intervention is essential; (2) co-ordination of services is fundamental to all service models; (3) services must be evidence-based; (4) involvement of significant others in service provision is highly desirable; (5) a personalised treatment approach is required for all patients; (6) education and/or psychoeducation is included in all interventions; (7) multidisciplinary care is required and (8) a skilled workforce is necessary. Seven general clinical practice standards are also discussed, including: (1) diagnosis and assessment; (2) the multidisciplinary care team; (3) a positive therapeutic alliance; (4) knowledge of evidence-based treatment; (5) knowledge of levels of care; (6) relapse prevention; and (7) professional responsibility. CONCLUSIONS These principles and standards provide guidance to professional training programs and service providers on the development of knowledge required as a foundation on which to build competent practice in the eating disorder field. Implementing these standards aims to bring treatment closer to best practice, and consequently improve treatment outcomes, reduce financial cost to patients and services and improve patient quality of life.

Abstract
This article presents current diagnostic conceptualisations of eating disorders, including new disorders such as binge eating disorder (BED) and avoidant/restrictive food intake disorder (ARFID). This is followed by contemporary findings in the epidemiology of eating disorders, their broad sociodemographic distribution and the increases in community prevalence. Advances and the current status of evidence‐based treatment and outcomes for the main eating disorders, anorexia nervosa, bulimia nervosa and BED are discussed with focus on first‐line psychological therapies. Deficits in knowledge and directions for further research are highlighted, particularly with regard to treatments for BED and ARFID, how to improve treatment engagement and the management of osteopenia.

Abstract
OBJECTIVE This systematic review and meta-analysis examine the contribution of duration to treatment outcome for eating disorders. METHOD Studies (n = 31) were identified that examined associations (r) between duration and 45 different outcomes. We were unable to extract r for seven studies (9 outcomes) and extracted r for 36 outcomes across 24 studies (2,349 participants). Indicators of treatment outcome were heterogeneous and thus a series of different meta-analyses, aimed at increasing homogeneity, were conducted. RESULTS First, we examined the average effect size for one primary eating disorder related outcome from each of the 24 studies. There was no association between duration and treatment outcome (r = .05, 95% CI: -.03:.13), with high heterogeneity. Second, we conducted three sub-group analyses to explore possible sources of heterogeneity (diagnosis: anorexia nervosa versus bulimia nervosa; nature of the outcome: binary versus continuous; or type of outcome: binary indicator of recovery, eating disorder psychopathology, weight gain). There was no significant moderation or associations between duration and outcome (ranging from .02-.08), with low to medium heterogeneity. Third, two stand-alone analyses examined outcomes related to weight gain (n = 8) and eating disorder psychopathology (n = 5), with nonsignificant rs of .23/-.06, respectively. High levels of heterogeneity were present. DISCUSSION Duration did not influence treatment outcome across any of our meta-analyses. Increasing homogeneity and power will allow more stable estimates of the impact of duration on outcome to be calculated; to this end, future treatment studies should include outcome related to weight gain (anorexia nervosa) and improvements in eating disorder psychopathology.

Abstract
BACKGROUND Outpatient interventions for adult anorexia nervosa typically have a modest impact on weight and eating disorder symptomatology. This study examined whether adding a brief online intervention focused on enhancing motivation to change and the development of a recovery identity (RecoveryMANTRA) would improve outcomes in adults with anorexia nervosa. METHODS Participants with anorexia nervosa (n = 187) were recruited from 22 eating disorder outpatient services throughout the UK. They were randomised to receiving RecoveryMANTRA in addition to treatment as usual (TAU) (n = 99; experimental group) or TAU only (n = 88; control group). Outcomes were measured at end-of-intervention (6 weeks), 6 and 12 months. RESULTS Adherence rates to RecoveryMANTRA were 83% for the online guidance sessions and 77% for the use of self-help materials (workbook and/or short video clips). Group differences in body mass index at 6 weeks (primary outcome) were not significant. Group differences in eating disorder symptoms, psychological wellbeing and work and social adjustment (at 6 weeks and at follow-up) were not significant, except for a trend-level greater reduction in anxiety at 6 weeks in the RecoveryMANTRA group (p = 0.06). However, the RecoveryMANTRA group had significantly higher levels of confidence in own ability to change (p = 0.02) and alliance with the therapist at the outpatient service (p = 0.005) compared to the control group at 6 weeks. CONCLUSIONS Augmenting outpatient treatment for adult anorexia nervosa with a focus on recovery and motivation produced short-term reductions in anxiety and increased confidence to change and therapeutic alliance.

Mousavi Asl E, Mahaki B, Gharraee B, Asgharnejad Farid AA, Shahverdi-Shahraki A. Beliefs about binge eating: The psychometric properties of the Persian version of the eating beliefs questionnaire. JOURNAL OF RESEARCH IN MEDICAL SCIENCES 2020; 25:73. [PMID: 33088310 PMCID: PMC7554542 DOI: 10.4103/jrms.jrms_623_19] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 11/26/2019] [Accepted: 03/23/2020] [Indexed: 12/12/2022]
Abstract
Background Metacognitive beliefs play an essential role in the maintenance of binge eating behavior. Examining the psychometric properties of tools in societies with different cultures than western societies can help with examining the external validity of those tools. This research aimed at standardization and validation of the Eating Beliefs Questionnaire (EBQ-18) in Iran. Materials and Methods Persian version of the EBQ-18 was produced through forward translation, reconciliation, and back translation. A total of 302 non-WEIRD nonclinical students were selected through convenience sampling method and completed a set of questionnaires, including the EBQ-18, Eating Attitude Test-16 (EAT-16), Difficulties in Emotion Regulation Scale-16 (DERS-16), Weight Efficacy Lifestyle Questionnaire-Short Form (SF), self-esteem scale, and self-compassion scale (SCS) short-form. The construct validity of the EBQ-18 was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (2 weeks' interval) were used to evaluate the reliability. Data analysis was performed using LISREL (version 8.8) and SSPS (version 22) softwares. Results EBQ-18 and subscales were found to be valid and reliable measures, with high test-retest reliability and good internal consistency in the nonclinical sample. Cronbrash's Alpha coefficient, for the whole of scale, negative beliefs scale, Permissive Beliefs scale, and Positive Beliefs scale were gained. 96.,89.,90, and. 94 respectively. Intraclass correlations coefficient, for the whole of scale, negative beliefs scale, Permissive Beliefs scale, and Positive Beliefs scale were gained. 84.,78.,75, and. 87, respectively. In terms of convergent validity, EBQ-18 and subscales showed a significant positive correlation with selfreport measures of EAT-16 and DERS-16 (P < 0.01). EBQ-18 and subscales showed a negative correlation with self-compassion, self-esteem, and eating self-efficacy, thus demonstrated divergent validity with these constructs (P < 0.01). The results showed that three factors of negative beliefs, positive beliefs, and permissive beliefs had the goodness of fit indices (root mean square error of approximation = 0.08, normed fit index = 0.97, nonnormed fit index = 0.98, comparative fit index = 0.98, and standardized root mean square residual = 0.04). The results of this study support the EBQ-18 three-factor model. Conclusion These findings indicate that the EBQ-18 is a reliable measure of eating beliefs in the Iranian population. In addition, the study supplements the literature on the cross-cultural validity of this measure.

Abstract
OBJECTIVE Parental involvement is emphasised in treatment guidelines for Eating Disorders (ED). The primary aim of this phase II study was to estimate the impact of a parent group intervention delivered immediately post-diagnosis on weight gain and ED psychopathology in a cohort of young people referred to a community ED service. A secondary aim was to identify predictor variables for early treatment response in children whose parents attended the programme. METHOD Parents of 64 new cases of Anorexia Nervosa (AN; n = 50) and Atypical Anorexia (AAN, n = 14) attended a 6 week parent group intervention in addition to treatment as usual in which patients were weighed and reviewed, but had no other contemporaneous psychological intervention. Age and gender adjusted BMI (%median [m] BMI) and ED psychopathology at baseline, 6-week and 6-month follow-up were analysed to assess weight gain and identify predictors of outcome. RESULTS The intervention was associated with weight gain and improved ED psychopathology by the end of the programme; these gains were sustained at 6 months %mBMI at 6 weeks was the only predictor of outcome (%mBMI) at 6 months. CONCLUSIONS This preliminary work highlights the positive benefit of an ED focused parent group early intervention that could be further evaluated.

Abstract
OBJECTIVE Self-esteem is a core aspect of eating disorder symptomatology. This study aims to examine whether method effects associated with negatively worded items of the Rosenberg Self-Esteem Scale (RSES) may interact the negative self-evaluations experienced by patients with obesity and binge eating disorder (BED). We also examined whether negatively worded items were associated with psychological distress and eating symptoms. METHOD Five hundred thirty three female outpatients (mean age: 42.59) with BED (n = 160) or obesity without BED (n = 373) completed the RSES and measures of interpersonal problems, psychological distress, and eating symptoms. RESULTS Patients with BED responded more strongly to the negatively worded items of the RSES than those with obesity. The RSES negatively worded item factor was negatively associated with higher interpersonal problems, psychological distress, and binge eating. CONCLUSIONS Patients with BED may be more responsive to negatively phrased items on the RSES consistent with their negative self-evaluations and self-perceptions.

Abstract
BACKGROUND Previous research has shown an association between burnout and low emotional competence (EC), defined as the ability to adequately regulate the intensity and expression of emotions. EC might also play a maintaining role in depression. The current paper aimed at studying the effect of improved EC on the course of burnout and depression. METHODS 113 psychiatric inpatients completed a set of standardized self-report questionnaires at intake, discharge and three months after treatment, assessing EC, burnout, and depression. Multi-level analyses investigated the effect of improved EC on burnout and depression. RESULTS Improved EC including a better emotion regulation during treatment predicted favourable treatment outcomes regarding burnout and depression symptoms. LIMITATIONS The present results should be considered in light of some methodological limitations. Most importantly, the patient sample consists of patients of one inpatient ward and is therefore not representative of all burnout patients. CONCLUSIONS This study supports EC as a putative mechanism of change in the multimodal treatment of inpatients with a stress-related depressive disorder and burnout. Clinical and research consequences of the findings will be discussed.

Abstract
OBJECTIVE Previous research supports the relevance of early symptom change in eating disorder (ED) treatment; however, few studies have distinguished early weight change from early change in ED psychopathology, particularly in higher levels of care. Thus, the present study examined whether early change in weight and ED psychopathology predicted outcome for adolescents with anorexia nervosa (AN) in a partial hospitalization program. METHOD Adolescents with AN (n = 99) completed assessments at admission, 1-month after treatment admission, discharge, and 6-month follow-up. RESULTS Higher admission percent expected body weight (%EBW), greater early change in %EBW, longer duration of treatment, shorter length of illness, and earlier age of onset predicted greater change in %EBW at discharge, but not follow-up. Greater ED psychopathology at admission and greater early change in ED psychopathology predicted later change in ED symptoms at discharge, but not follow-up. Neither early change in %EBW nor ED psychopathology predicted likelihood of remission at discharge and follow-up. DISCUSSION Results support the importance of early change in predicting later change in the same ED outcome variables and suggest that early change in both %EBW and ED psychopathology in adolescents may be an important area for future research.

Abstract
OBJECTIVE The purpose of the study was to identify latent classes of trajectory of change in body mass index (BMI) between the initial and thirteenth session of outpatient treatment for adult anorexia nervosa and identify the association with outcome. METHOD Participants (n = 120) were randomised to one of three outpatient therapies. RESULTS Four latent classes were identified; two classes (higher, rapid and higher, moderate) had BMI > 17 kg/m2 at initial assessment, and both gained significantly more weight over the 13 sessions compared to the other two classes. The third and fourth classes (middle, stable and low, stable) had an initial BMI of 16.44 and 15.31, respectively, and neither gained weight over the first 13 sessions. Compared to the other three classes, the higher, rapid class (N = 19, 16%) showed a significantly greater BMI increase over the first 13 sessions of therapy and a significantly higher rate of remission at end of treatment and 12-month follow-up (18-22 months post-randomisation). CONCLUSIONS The group with the greatest early weight gain had significantly higher levels of remission. Higher BMI at baseline without substantial early weight gain was insufficient to produce higher levels of remission than those with lower weight at baseline.

Abstract
BACKGROUND Variation in genes implicated in homocysteine and lipid metabolism systems may influence antidepressant response for patients with major depressive disorder (MDD). This study aimed to investigate whether association of polymorphisms on the MTHFR, ApoE and ApoA4 genes with the treatment response in MDD subjects. METHODS A total of 281 Han Chinese MDD patients received a single antidepressant drug (SSRI or SNRI) for at least 6 weeks, among whom 275 were followed up for 8 weeks. Their response to 6 weeks' treatment and remission to 8 weeks' treatment with antidepressant drugs was determined by changes in the 17-item Hamilton Depression Rating Scale (HARS-17) score. Single SNP and haplotype associations with treatment response were analyzed by UNPHASED 3.0.13. Logistic regression analysis was used to explore the interactions between genotypes and gender or drug type on treatment outcome, only those SNPs that had interactional association with gender or drug type were subjected to further stratified analysis. RESULTS In total group, the haplotype (C-A) in MTHFR (rsl801133 and rs1801131) and the ApoE rs405509 AA genotype were significantly associated with better efficacy of antidepressants; In gender subgroups, only haplotype (C-A) in MTHFR (rsl801133 and rs1801131) was significantly associated with better efficacy of antidepressants in male subgroup; In drug type subgroup, the haplotype (C-A) in MTHFR (rsl801133 and rs1801131) and haplotype (G-C) in ApoE (rs7412 and rs405509) were associated with better efficacy of antidepressants in SNRI treated subgroup; The ApoA4 rs5092 G allele and GG genotype were associated with worse efficacy of antidepressants in SNRI treated subgroup. CONCLUSIONS Genetic polymorphisms in homocysteine and lipid metabolism systems are associated with antidepressant response, particularly for the interactions of the certain genetic with gender or drug type.

Abstract
OBJECTIVE It is difficult for individuals with eating disorders (EDs) to build and maintain motivation to recover. This challenge contributes to high rates of treatment dropout and relapse. To date, motivational interventions have been largely ineffective, and there is little research on factors that affect recovery motivation. To better understand recovery motivation and identify potential intervention targets, this study examines factors that affect recovery motivation in individuals with EDs. METHOD N = 13 participants completed qualitative interviews. All had been recovered from their diagnosed and treated ED for at least 1 year. We applied thematic analysis to interview transcripts in order to identify factors that had influenced recovery motivation and to classify their effects as helpful, harmful, or mixed. RESULTS Six main themes were identified, with subthemes detailed under each: (a) important people and groups (e.g., social circle, mentor), (b) actions and attitudes of others (e.g., judgmental responses, failure to intervene), (c) treatment-related factors (e.g., therapeutic skills, therapeutic alliance), (d) influential circumstances (e.g., removing triggers, pregnancy/children), (e) personal feelings and beliefs (e.g., obligation to others, hope for the future), and (f) the role of epiphanies (i.e., sudden insights or moments of change). DISCUSSION In this study, we identified potentially malleable factors that may affect ED recovery motivation (e.g., removing triggers, focusing on obligation to others, getting involved in meaningful causes, securing non-judgmental support, building hope for the future). These factors may be investigated as potential targets or strategies in motivational interventions for EDs.

Abstract
OBJECTIVE Nutrition restoration in inpatients with anorexia nervosa (AN) is a core element in treatment, enabling recovery of cognitive functions essential for psychological care. This study aims to identify factors associated with inpatient weight gain. METHODS Medical records from 107 inpatients aged 13-55 years with AN, hospitalized for more than 7 days at a specialized unit, were examined in a retrospective study. Weight evolution graphs were created for each patient and graded independently as optimal, moderate, and inadequate weight gain after 2 weeks and increasing, flat or decreasing weight in the first 2 weeks by expert clinicians. Driven by explicit hypotheses, bivariable analyses were carried out to detect relevant factors associated with weight gain during and after the first 2 weeks of admission. RESULTS Initial weight gain in the first 2 weeks of hospitalization and the introduction of a protocol harmonizing treatment procedures around rapid refeeding were strong factors associated with optimal weight gain after 2 weeks of hospitalization, whereas prior hospitalization in a psychiatric unit, diagnosis with binge-eating/purging subtype and age over 18 years were significantly associated with inadequate weight gain (p < 0.001-0.05). CONCLUSION To promote weight gain during hospitalization, clinicians should consider the following therapeutic measures: rapid refeeding strategies, renutrition protocols, and controlling purging behaviors. LEVEL OF EVIDENCE Level III, retrospective cohort study.

Abstract
OBJECTIVE Cognitive-behavioural therapy (CBT) is an efficacious and effective treatment for eating disorders, and is particularly valuable in the treatment of non-underweight cases (e.g., bulimia nervosa; binge eating-disorders). However, its recommended length for such cases (up to 20 sessions) makes it a relatively costly therapy. It has been suggested that a 10-session version (CBT-T) can also be effective, but there has been no direct comparison between the two forms (10 vs. 20 sessions). METHOD This study reports the outcomes of brief and standard-length CBT for non-underweight eating disorders, comparing two cohorts of patients from the same clinic (N = 55 and 138, respectively). RESULTS The two therapies had very similar results in terms of eating pathology, remission rate, and improved quality of life. Each showed substantial change by the mid-point of therapy and up to 6-month follow-up. CONCLUSION It appears that brief CBT (CBT-T) is as effective as existing 20-session CBT, and is less demanding of time and resource. The findings need to be replicated in a randomized control trial before this conclusion can be made definitive.

Abstract
PURPOSE The aim of this study was to investigate the predictive value of early changes in depression levels during inpatient treatment of adolescent anorexia nervosa (AN). METHODS Fifty-six adolescents (88% girls) aged 10-18 years (M = 15.35, SD = 2.23) diagnosed with AN were assessed at admission and 1 month following admission to an inpatient setting. Depression levels and eating disorder symptoms were reported at both assessments. Re-hospitalization within 12 months of discharge was documented using official national records. RESULTS Whereas depression levels at baseline were found equivalent between subsequently re-hospitalized and non-re-hospitalized patients, at 1 month after admission patients who were later re-hospitalized had higher levels of depression compared to those who were not re-hospitalized. These differences remained significant after controlling for weight gain and anti-depressant medication intake. We additionally found that the proportion of boys in the non-re-hospitalized group was substantially larger than their proportion in the re-hospitalized group. CONCLUSIONS Our results suggest that depression at the point of hospital admission may not be a reliable predictor of treatment outcomes, and highlight the risk of relapse in AN patients whose depression levels do not alleviate after a month of inpatient treatment. Clinicians should consider providing more adjusted and intensive attention to such patients in their efforts to facilitate remission. LEVEL OF EVIDENCE III Well-designed cohort study.

Not all body image constructs are created equal: Predicting eating disorder outcomes from preoccupation, dissatisfaction, and overvaluation. Int J Eat Disord 2020; 53:954-963.

Abstract
OBJECTIVE Diverse terminology has been used to operationalize body image disturbance in eating disorders. However, the differential validity of these terms and their underlying constructs to predict outcomes among heterogeneous eating disorders is unknown. This study evaluated the validity of body image constructs to predict eating disorder and negative psychological symptoms concurrently and prospectively over 2 years in a transdiagnostic clinical sample. METHODS Women with heterogeneous eating disorder diagnoses (n = 448) completed assessments at baseline, 12-month, and 24-month follow-up. Cross-sectional and cross-lagged generalized linear models examined effects of three body image constructs (i.e., weight and shape preoccupation, overvaluation, and dissatisfaction) on concurrent and subsequent outcomes (i.e., global eating disorder symptoms, binge eating, purging, fasting, self-esteem, and depression). RESULTS In concurrent analyses, preoccupation was significantly associated with all outcomes (ps = .01 to <.001), overvaluation with all outcomes (ps = .01 to <.001) except binge eating (p = .06), and dissatisfaction with all outcomes (ps < .001) except purging (p = .38). In prospective analyses, preoccupation predicted Eating Disorder Examination global (p = .003) and fasting (p < .001), overvaluation predicted binge eating (p = .01), and body dissatisfaction did not predict any outcomes. DISCUSSION Preoccupation, overvaluation, and dissatisfaction are differentially related to eating disorder and psychiatric outcomes, indicating that no one body image construct can capture clinical risk in eating disorders. Preoccupation was the most consistent concurrent and longitudinal predictor; this construct may warrant further attention in assessment and diagnosis. Further investigation of these constructs in diverse samples is encouraged.

Abstract
OBJECTIVE Our goal was to examine potential predictors of a comprehensive operationalization of eating disorder recovery, characterized by physical, behavioral, and cognitive recovery, focusing on constructs related to self-concept, personality, and negative affect. METHOD Participants were women with a history of an eating disorder who provided data via survey and interview at two time points separated by about 7-8 years and who met criteria for an eating disorder diagnosis at baseline (N = 36). RESULTS Logistic regression models revealed that self-esteem was a significant predictor of recovery status (OR = 1.12, p = .039) such that individuals with higher self-esteem at baseline demonstrated significantly greater odds of being in full recovery at follow-up. However, when self-esteem was considered in a set along with baseline imposter phenomenon and anxiety, no single construct emerged as a significant unique predictor of recovery in logistic regression analyses. DISCUSSION These results highlight the potential importance of self-esteem in relation to recovery, with clinical implications related to bolstering self-esteem as part of eating disorder treatment. Future research should continue to explore predictors using a comprehensive operationalization of eating disorder recovery in larger, more diverse samples to optimally identify factors associated with achieving recovery.

Abstract
Binge eating disorder (BED) is a mental illness characterised by recurrent binge eating episodes in the absence of appropriate compensatory behaviours. Consequently, BED is strongly associated with obesity. The current review aims to provide an update of the most relevant aspects of BED (e.g., clinical profile, aetiology and treatment approaches), in order not only to facilitate a better understanding of the disorder and its clinical consequences, but also to identify potential targets of prevention and intervention. Patients with BED often present high comorbidity with other medical conditions and psychiatric disorders. Numerous risk factors have been associated with the development and maintenance of the disorder. Moreover, although some treatments for BED have proven to be effective in addressing different key aspects of the disorder, the rates of patients that have ever received specific treatment for BED are very low. The factors involved and how to implement effective treatments will be discussed for the purpose of addressing the eating symptomatology and comorbid obesity.

Abstract
OBJECTIVE The current study examined predictors and moderators of two interventions for binge-eating disorder (BED). METHOD Participants were 112 adults with BED (Mage = 39.7 ± 13.4 years; MBMI = 35.1 ± 13.4 kg/m²; 82% female; 91% Caucasian) randomly assigned to integrative cognitive-affective therapy for BED (ICAT-BED) or guided self-help cognitive-behavioral therapy (CBTgsh). Generalized linear models examined predictors and moderators of objective binge-eating episode (OBE) frequency and OBE abstinence at end-of-treatment (EOT) and 6-month follow-up (FU). RESULTS Lower levels of baseline dietary restraint and emotion regulation difficulties predicted greater reductions in OBE frequency at EOT and FU, respectively. At EOT, greater pretreatment self-control predicted greater reductions in OBE frequency in ICAT-BED than CBTgsh (ps < .05). In addition, low shape/weight overvaluation predicted greater reductions in OBE frequency in ICAT-BED than CBTgsh, whereas high shape/weight overvaluation predicted comparable reductions in OBE frequency across treatments at EOT (ps < .02). At EOT and FU, greater baseline actual-ideal self-discrepancy predicted significantly greater reductions in OBE frequency in ICAT-BED, than CBTgsh (ps < .02). No significant predictor or moderator effects were observed for models examining OBE abstinence. CONCLUSION This study identified two general predictors and four moderators of BED treatment response. However, only one predictor (actual-ideal self-discrepancy) interacted with treatment type to differentially predict OBE frequencies at both EOT and FU. Altogether, findings suggest that ICAT-BED may confer specific and durable improvements in OBE frequencies among individuals with high actual-ideal self-discrepancy. Therefore, patients demonstrating these characteristics may be more likely to benefit from ICAT-BED. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
