Eating disorders and social anxiety are highly co-occurring. These disorders share fears of social evaluation, possibly maintained by similar cognitive content and styles, including an inability to adapt or flexibly respond to unexpected conditions. However, the role of cognitive inflexibility in eating disorders in relation to social anxiety has not been explored.
Objective: In this study, the link between eating disorder symptoms and cognitive inflexibility, while accounting for social anxiety, is examined.
Method: Participants (N=461) were undergraduates who completed the Detail and Flexibility Questionnaire 12-item Cognitive Rigidity subscale, the Eating Disorders Diagnostic Scale, and the Social Interaction Anxiety Scale.
Results: Eating disorder symptoms and social anxiety were both positively correlated with cognitive inflexibility. After controlling for social anxiety, the relationship between eating disorder symptoms and cognitive inflexibility remained robust.
Discussion: Further examination of cognitive inflexibility in eating disorders and comorbid social anxiety in clinical samples is warranted. We suggest future directions for examining cognitive inflexibility as a trans-diagnostic construct important to eating disorders and frequently comorbid disorders, consistent with NIMH Research Domain Criteria.
