<p>Dialectical behaviour therapy (DBT) is a promising treatment option for binge eating disorder (BED). It addresses affective and behavioural patterns such as difficulties in emotional management (e.g., emotion dysregulation) and the loss of control in eating behaviours (e.g., emotional eating). However, conclusions drawn from the literature were identified to be largely confounded by the overgeneralisation of eating disorders (e.g., treating BED and bulimia nervosa as the same diagnosis) and the mix of different subtypes of DBT (e.g., group-based treatment; self-guided treatment). This review examined various treatment outcomes in individuals with BED. Ten eligible studies were identified in a systematic search, including 656 participants from five study regions. While group-based DBT appeared to be effective in addressing most of the examined treatment outcomes, its efficacy was generally less favourable when compared to cognitive behavioural therapy. Various limitations within the included studies were also identified, negatively impacting collective study quality.</p>
