Show moreBackgroundE-mental health has become increasingly popular in interventions for individuals with eating disorders (EDs). It has the potential to offer low-threshold interventions and guide individuals to the needed care more promptly. Featback is such an Internet-based intervention and consists of psychoeducation and a fully automated monitoring and feedback system. Preliminary findings suggest Featback to be (cost-)effective in reducing ED symptomatology. Additionally, e-mail or chat support by a psychologist did not enhance the effectiveness of Featback. Support by an expert patient (someone with a lived experience of an ED) might be more effective, since that person can effectively model healthy behavior and enhance self-efficacy in individuals struggling with an ED. The present study aims to replicate and build on earlier findings by further investigating the (cost-)effectiveness of Featback and the added value of expert-patient support.MethodsThe study will be a randomized controlled trial with a two-by-two factorial design with repeated measures. The four conditions will be (1) Featback, in which participants receive automated feedback on a short monitoring questionnaire weekly, (2) Featback with weekly e-mail or chat support from an expert patient, (3) weekly support from an expert patient, and (4) a waiting list. Participants who are 16 years or older and have at least mild self-reported ED symptoms receive a baseline measure. Subsequently, they are randomized to one of the four conditions for 8 weeks. Participants will be assessed again post-intervention and at 3, 6, 9, and 12 months follow-up. The primary outcome measure will be ED psychopathology. Secondary outcome measures are experienced social support, self-efficacy, symptoms of anxiety and depression, user satisfaction, intervention usage, and help-seeking attitudes and behaviors.DiscussionThe current study is the first to investigate e-mental health in combination with expert-patient support for EDs and will add to the optimization of the delivery of Internet-based interventions and expert-patient support.Trial registrationNetherlands Trial Register, NTR7065.

Show moreExecutive functions are a set of cognitive processes that are necessary for the cognitive control of behavior. They play a role in mediating self-control, self-regulation and decision-making. It has been suggested that the inability to control eating behavior in binge eating disorder (BED) may indicate deficits in executive functioning. This may be worsened by depressive symptoms. The aim of the present study was to compare executive functioning of patients with BED and no-to-mild depressive symptoms (n = 25), patients with BED and moderate-to-severe depressive symptoms (n = 66), and healthy controls (Body Mass Index <30) (n = 56), matched on age, educational level and gender. The participants were assessed by means of neuropsychological tests and questionnaires. The neuropsychological tests did not show significant differences in executive functioning between the groups. However, eating disorder psychopathology and depressive symptoms are associated with self-reported difficulties in executive functioning in daily life. A self-report questionnaire which evaluates the functional, real-world impact of executive dysfunction expressed in everyday activities seems to be more useful in this population than neuropsychological tests. This study highlights the importance of taking depressive symptoms into account when studying executive functioning in patients with (binge) eating disorders. Show less
