- Abstract
Objective: This study examined the distinctiveness of specific constructs of body‐image disturbance in patients with anorexia nervosa (AN) and bulimia nervosa (BN). We compared weight/shape dissatisfaction, weight/shape overvaluation, weight/shape preoccupation, and fear of weight gain in patients with AN and BN and examined how each specific body‐image construct relates to clinical measures within and between AN and BN. Method: A clinical sample of 490 treatment‐seeking patients diagnosed with DSM‐5 AN (N = 310) or BN (N = 180) by clinicians using structured interviews in Portugal completed the Eating Disorder Examination‐Questionnaire to assess body image and eating‐disorder (ED) psychopathology. Results: Both within and between AN and BN, the four body‐image constructs varied in their strengths of association among themselves, with ED psychopathology, and body mass index (BMI). Analyses revealed considerable variability in variance accounted for in clinical measures by body‐image constructs. Body‐image constructs predicted significant, albeit small, variance in BMI within BN (dissatisfaction, preoccupation significant) but not within AN. Body‐image constructs predicted significant, albeit small, variance in the frequencies of binge eating and purging in AN (with preoccupation significant for both and fear for purging) but not within BN. Body‐image constructs predicted significant variance in ED psychopathology (large amounts of variance for Eating Concern and Restraint) within both AN and BN (with overvaluation, preoccupation, and fear significant). Conclusion: Clinical manifestations of body‐image disturbances are complex and show important differences across AN and BN. Understanding distinctions and differential salience of different body‐image constructs across different EDs can inform refinement of specific case conceptualization.
