Objective: The present study evaluated the feasibility and acceptability of cognitive behavioural guided self-help (CBTgsh) for recurrent binge eating using the train-the-trainer implementation strategy.
Method: After receiving expert-led training in CBTgsh, a master's-level graduate student in clinical psychology subsequently trained and supervised less experienced graduate students to implement the treatment in an open clinical trial. Participants were 38 treatment-seeking students at a university counselling centre with recurrent binge eating, featuring cases of bulimia nervosa, binge eating disorder, or eating disorder not otherwise specified.
Results: Intent-to-treat (ITT) analyses revealed 42.1% abstinence from binge eating at post-treatment and 47.4% at one-month follow-up. Participants reported significant pretreatment to post-treatment reductions on measures of specific eating disorder psychopathology, general psychopathology, and functional impairment and high levels of treatment acceptability.
Conclusions: These results provide 'proof-of-concept' for the train-the-trainer implementation strategy and add to the evidence supporting the feasibility and effectiveness of CBTgsh in routine clinical care.

Binge eating (BE) is associated with psychological distress, functional impairment, and elevated risk of eating disorder diagnoses, and BE prevalence is increasing. Motivational and self-regulatory processes such as delay discounting may be important influences on BE; however, evidence is inconclusive, and lacks explanation of mechanisms. This study investigated how food choice motives mediate the pathway from delay discounting (DD) to BE symptomatology.

Background/objectives: Like in the general population, the prevalences of eating- and weight-related health issues in the armed forces are increasing. Relevant medical conditions include the eating disorders (EDs) anorexia nervosa, bulimia nervosa, binge eating disorder, and avoidant restrictive food intake disorder (ARFID), as well as body dysmorphic disorder, muscle dysmorphia, and the relative energy deficiency in sport (RED-S) syndrome.
Methods: We performed a narrative literature review on eating- and weight-related disorders in the armed forces.

Binge eating (BE) is a highly pervasive maladaptive coping strategy in response to severe early life stress such as emotional and social neglect. BE is described as repeated episodes of uncontrolled eating and is tightly linked with comorbid mental health concerns. Despite social stressors occurring at a young age, the onset of BE typically does not occur until adulthood providing an interval for potential therapeutic intervention.

Background: Current treatments for adolescents with eating disorders (ED) show limited effectiveness, emphasizing the need for enhanced therapeutic approaches. Cognitive behavioral therapy (CBT) has emerged as a potential alternative. A derivative of this approach, group cognitive behavioral therapy (G-CBT), has been shown to reduce treatment costs and increase treatment accessibility when compared to CBT.

Ali et al.'s (2024) systematic review and meta-analysis updated a previous meta-analysis on the gap between the need for eating disorder treatment and rates of seeking and receiving eating disorder treatment. They found that less than one-third of individuals with eating disorders sought help for their eating disorder, which was an improvement of only 8% over more than a decade.
