This study examined the factorial structure and diagnostic efficiency of the DSM-IV criteria for avoidant personality disorder (AVPD). Two hundred and twenty-eight consecutive outpatients (181 females and 47 males) with a primary diagnosis of binge eating disorder were reliably assessed with diagnostic interviews. Internal consistency of AVPD criteria was good, as suggested by coefficient alpha of 0.87, the pattern of inter-item correlations (range 0.41 to 0.64), and the lack of changes in alpha if any criteria are deleted. Exploratory factor analysis revealed a one-factor solution (56% of variance) supporting the unidimensionality of the AVPD criteria. Diagnostic efficiency indices (conditional probabilities, total predictive power, and kappa coefficients) were calculated for each AVPD criterion, for the entire study group and separately by gender. Overall, the best inclusion criterion was ‘fears being ridiculed,’ which was also the best predictor overall. These psychometric findings did not differ by gender. The findings support certain important aspects of the AVPD diagnosis.
