Background: Dialectical behavior therapy (DBT) is a specialized treatment that has a growing evidence base for binge-spectrum eating disorders. However, cost and workforce capacity limit wide-scale uptake of DBT since it involves over 20 in-person sessions with a trained professional (and six sessions for guided self-help format). Interventions translated for delivery through modern technology offer a solution to increase the accessibility of evidence-based treatments.

There is growing enthusiasm towards the role of smartphone app-based interventions in the management of insomnia and related sleep problems. A considerable number of apps designed to address insomnia have been developed in recent years, and randomized controlled trials (RCTs) have begun to explore their efficacy. We conducted a meta-analysis investigating the effectiveness of apps for insomnia and sleep disturbances.

Objective: Theoretical models highlight body image disturbances as central to the maintenance of eating disorders, with empirical evidence finding negative body image to be a robust predictor of treatment nonresponse, relapse and symptom persistence. Accessible, scalable, and inexpensive interventions that can effectively target negative body image across the eating disorders are needed. We developed an online single session intervention (SSI) for negative body image and evaluated its acceptability and efficacy in a randomized controlled trial in individuals with recurrent binge eating.

Muscularity-oriented disordered eating (MODE) is a novel class of eating behaviors characterised by abnormal dietary alterations aimed towards building lean muscle. Although traditionally shown to affect men, emerging evidence suggests that increasingly more women are striving for the muscular and lean ideal, resulting in engagement of MODE behaviors. Prior research examining MODE in women is limited, yet emerging evidence from cross-sectional studies have established associations between MODE and poor mental health indices in this population.

Recent evidence shows that negative body image may be a potential risk factor for symptoms of orthorexia nervosa (ON). However, whether positive body image plays a protective role against symptoms of ON remains unclear. Although prior research has established associations between body appreciation (a core component of positive body image) and ON symptoms, this research is limited to cross-sectional designs, precluding inferences of temporal precedence.

The immune isolation of cells within devices has the potential to enable long-term protein replacement and functional cures for a range of diseases, without requiring immune suppressive therapy. However, a lack of vasculature and the formation of fibrotic capsules around cell immune-isolating devices limits oxygen availability, leading to hypoxia and cell death in vivo. This is particularly problematic for pancreatic islet cells that have high O requirements.

The possible mental health impacts of orthorexia nervosa (ON) symptoms are poorly understood, as existing research in this field has mostly employed cross-sectional designs. This study investigated whether ON symptoms prospectively predict changes in eating disorder psychopathology and general mental health. A convenience, non-clinical sample of adults (n = 313; 83 % women) completed study measures at baseline (T1) and three-month follow-up (T2).

Emerging theoretical and empirical evidence indicates that negative body image might be implicated in the onset or maintenance of ON symptoms. However, existing research investigating associations between negative body image and ON is limited to cross-sectional designs and has failed to consider the independent role of distinct components of body image. To overcome these limitations, the present study examined the prospective associations between five components of body image (i.

Background: Theoretical models highlight the importance of emotion dysregulation as a key risk and maintaining factor for eating disorders. However, most studies testing these theories are cross-sectional. It remains unclear which dimensions of emotion dysregulation account for the onset and persistence of eating disorder behaviours over time.
