Background: Mental disorders during pregnancy and the postpartum period can have far-reaching consequences. To enhance peripartum mental well-being and prevent peripartum mental disorders, internet- and mobile-based interventions appear promising. They can overcome help-seeking barriers associated with face-to-face conditions and have proven to be effective.

Background: Although effective treatments for bulimic-spectrum eating disorders exist, access is often delayed because of limited therapist availability and lengthy waiting lists. Web-based self-help interventions have the potential to bridge waiting times for face-to-face treatment and overcome existing treatment gaps.

Aims: This study aims to assess the effectiveness of a web-based guided self-help intervention (everyBody Plus) for patients with bulimia nervosa, binge eating disorder and other specified feeding and eating disorders who are waiting for out-patient treatment.

Background: A growing body of evidence for digital interventions to improve sleep shows promising effects. The interventions investigated so far have been primarily web-based; however, app-based interventions may reach a wider audience and be more suitable for daily use.

Objective: This study aims to evaluate the intervention effects, adherence, and acceptance of an unguided app-based intervention for individuals who wish to improve their sleep.

Background: Although preventive interventions for eating disorders in general have shown promise, interventions specifically targeting individuals at risk for anorexia nervosa (AN) are lacking.

Objective: The aim of this study was to determine the efficacy of a guided, indicated web-based prevention program for women at risk for AN.

Methods: We conducted a randomized controlled efficacy trial for women at risk for AN.

Background: Online preventive interventions can help to reduce the incidence of mental disorders. Whereas knowledge on stakeholders' attitudes and factors relevant for successfully integrating online treatment into existing healthcare systems is available, knowledge is scarce for online prevention.

Methods: Stakeholders from Germany, Switzerland, Austria and Spain were surveyed.

Objective: Using data from a randomized controlled trial, we examined two different strategies to recruit participants for an indicated preventive intervention (StudentBodies-AN) for women at risk for anorexia nervosa and compared symptom severity and program utilization in participants recruited through each strategy.

Method: We recruited participants by announcing the study (a) in lectures at universities and handing out screening questionnaires (face-to-face recruitment) and (b) through different media channels, and the participants completed the screening questionnaire on our study website (media-based recruitment). We compared symptom severity and program utilization between the two groups.

Background: Adherence reflects the extent to which individuals experience or engage with the content of online interventions and poses a major challenge. Neglecting to examine and report adherence and its relation to outcomes can compromise the interpretation of research findings.

Objective: The aim of this systematic review is to analyze how adherence is accounted for in publications and to propose standards for measuring and reporting adherence to online interventions.

Background: Body dissatisfaction and dietary restraint are established risk factors for eating disorders and are also prevalent in individuals who are overweight and obese. Studies have shown that online prevention programs can lower these risk factors. The aim of this feasibility pilot study was to estimate effects of a 12-week online health promotion and eating disorder prevention program in a sample of women with overweight or obesity, but without binge eating.

Background: Anorexia nervosa (AN) is a life-threatening mental disorder that is associated with substantial caregiver burden. Carers of individuals with AN report high levels of distress and self-blame, and insufficient knowledge to help their loved ones. However, carers can have a very important role to play in aiding recovery from AN, and are often highly motivated to assist in the treatment process.

Background: Eating disorders are serious conditions associated with an impaired health-related quality of life and increased healthcare utilization and costs. Despite the existence of evidence-based treatments, access to treatment is often delayed due to insufficient health care resources. Internet-based self-help interventions may have the potential to successfully bridge waiting time for face-to-face outpatient treatment and, thus, contribute to overcoming treatment gaps.

Background: Although there is extensive evidence for the efficacy of online eating disorder (ED) prevention programs in clinical trials, these programs have rarely been adopted beyond the trial phase and offered to a wider audience. As risk factors for eating disorders are partly associated with overweight and overweight in turn is correlated to disordered eating, this study will offer a combined eating disorder prevention program which also promotes a balanced lifestyle to normal weight and overweight individuals alike. The efficacy of the program has been proven in previous trials.

The current study examined, for the first time, the effect of cue-intention association, as well as the effects of promised extrinsic rewards, on prospective memory in young children, aged 5-years-old (n = 39) and 7-years-old (n = 40). Children were asked to name pictures for a toy mole, whilst also having to remember to respond differently to certain target pictures (prospective memory task). The level to which the target picture was associated with the intention was manipulated across two conditions (low- or high-association) for all participants, whilst half of the participants were promised a reward for good prospective memory performance.
