| Abstract: | Objective: Heightened sensitivity toward social rejection has been implicated in eating disorders (ED) and personality disorder (PD). This study examined the effect of a cognitive bias modification training (CBM‐I) targeting the interpretation of ambiguous social situations in individuals with comorbid ED and PD. Method: A total of 128 participants [33 with ED and PD, 22 with ED‐only, 22 with PD‐only, and 51 healthy controls (HC)] were recruited from a hospital and university settings, and included in the final analyses. The participants were randomly assigned to a CBM‐I task with benign resolutions or a control task with neutral resolutions in a counterbalanced order in two sessions using a within‐subject design. Interpretation bias toward social stimuli was measured using the ambiguous sentence completion task before and after completing the assigned task. Results: The CBM‐I task increased benign and decreased negative interpretations with large effect sizes in the diagnostic groups, and with a moderate effect size in the HC group. Participants' anxiety levels were also reduced after the task. The size of the change in negative interpretation was positively associated with baseline negative affect, and negatively associated with baseline positive affect. Discussion: The results suggest that modifying interpretation bias has the potential as a transdiagnostic target of treatment for ED and PD, and a fully powered clinical trial with consecutive sessions would be warranted. Public Significance: Participants with eating disorders and/or personality disorder, and healthy controls completed a single session of a cognitive training intervention targeting rejection sensitivity. The training produced a large decrease in negative interpretation in the diagnostic groups, and a moderate effect in healthy controls. The findings indicate that training for positive processing of social information may be of value to augment treatment in conditions such as eating disorders and personality disorder, in which there are high levels of rejection sensitivity.
