“…In terms of clinical predictors, our results showed an association between ED psychopathology and CBT outcome: The higher the ED psychopathology, the lower the probability of ED symptomatological remission. These results are in accordance with previous literature (Dakanalis, Colmegna, Riva, & Clerici, ; Lammers, Vroling, Ouwens, Engels, & van Strien, ; Vroling, Wiersma, Lammers, & Noorthoorn, ; Wagner et al, ) reporting that ED psychopathology, such as binge eating episodes and shape/weight concerns, are significant predictors of dropout, and high levels of body dissatisfaction are associated with poor outcomes. In addition, our results also showed that age played an important role in the prognosis of these disorders.…”

Objectives:The study aimed to examine whether food addiction (FA) was associated with greater severity in both binge eating disorders (BED) and bulimia nervosa and, therefore, to determine if FA was predictive of treatment outcome.Method: Seventy-one adult patients with bulimia nervosa and BED (42 and 29, respectively) participated in the study. FA was assessed by means of the Yale Food Addiction Scale. Results:The results confirmed a high prevalence of FA in patients with binge disorders (around 87%) and also its association with a greater severity of the disorder (i.e., related to an increased eating psychopathology and greater frequency of binge eating episodes). Although FA did not appear as a predictor of treatment outcome in general terms, when the diagnostic subtypes were considered separately, FA was associated with poor prognosis in the BED group. In this vein, FA appeared as a mediator in the relationship between ED severity and treatment outcome.Discussions: Our findings suggest that FA may act as an indicator of ED severity, and it would be a predictor of treatment outcome in BED but not in BN.Xandra Romero and Zaida Agüera shared first authorship.

“…Within the past few years, several studies examined Internet‐based guided self‐help (GSH‐I) for eating disorders because of its potential to improve reach and dissemination of evidence‐based face‐to‐face treatment (e.g., Aardoom, Dingemans, & van Furth, ; Bauer & Moessner, ; de Zwaan et al, ; Kazdin, Fitzsimmons‐Craft, & Wilfley, ; König et al, ; Melioli et al, ; Wagner et al, ). Benefits of GSH‐I include the relative anonymity of the Internet, its widespread and unlimited availability, and thus low threshold for patients to access and complete psychological interventions (Schlegl, Bürger, Schmidt, Herbst, & Voderholzer, ; ter Huurne et al, ).…”

Objective: Internet-based guided self-help (GSH-I) is an efficacious treatment for adults with binge-eating disorder (BED) and overweight or obesity. Although broadly accessible, high dropout from GSH-I has been reported. However, little is known about the factors explaining dropout from GSH-I, including patients' adherence to treatment.Method: Within a randomized trial on the treatment of BED, adherence to 4-month GSH-I was objectively assessed in N = 89 patients with BED and overweight or obesity. Objective adherence and subjective treatment evaluation were evaluated as predictors of dropout from GSH-I, defined as having accessed 5 or less of 11 modules.Cutoffs with optimal sensitivity and specificity were derived using Receiver Operating Characteristics curves analysis, and baseline sociodemographic and clinical correlates were determined.Results: According to our definition, n = 22 (24.7%) patients were defined as dropouts. Results of the full logistic regression model accounted for 72% of the variance in dropout and all objective adherence parameters (i.e., number of messages exchanged, days with a completed food diary, and days spent per module), but not patients' subjective GSH-I evaluation significantly predicted dropout. Specifically, not completing the food diary in week 7 had maximized sensitivity and specificity in predicting dropout. Patients' body mass index was positively associated with the number of messages exchanged between patients and coaches. No other associations between baseline variables and objective adherence were found.Martina de Zwaan and Anja Hilbert contributed equally to this study.

“…In order to detect a difference for the primary outcome (General Health Questionnaire, see Sepulveda, Lopez, Todd, et al, 2008) by calculating repeated measures analysis of variance (ANOVA; if the sphericity assumption is not met) at a 5% significance level with 0.88 power, carers of 40 patients per group are needed to detect medium effects (Faul, Erdfelder, Lang, & Buchner, 2007). We expect a dropout rate of about 17% (see Wagner et al, 2015). Therefore, we plan to include the carers of 48 patients per treatment arm, resulting in a total sample size of 144.…”

Supporting Carers of Children and Adolescents with Eating Disorders in Austria (SUCCEAT) is an intervention for carers of children and adolescents with anorexia nervosa and atypical anorexia nervosa. This paper describes the study protocol for a randomised controlled trial including the process and economic evaluation. Carers are randomly allocated to one of the 2 SUCCEAT intervention formats, either 8 weekly 2‐hr workshop sessions (n = 48) or web‐based modules (n = 48), and compared with a nonrandomised control group (n = 48). SUCCEAT includes the cognitive‐interpersonal model, cognitive behavioural elements, and motivational interviewing. The goal is to provide support for carers to improve their own well‐being and to support their children. Outcome measures include carers' distress, anxiety, depression, expressed emotions, needs, motivation to change, experiences of caregiving, and skills. Further outcome measures are the patients' eating disorder symptoms, emotional problems, behavioural problems, quality of life, motivation to change, and perceived expressed emotions. These are measured before and after the intervention, and 1‐year follow‐up.
