Abstract

To evaluate the relationships between body dysmorphic disorder (BDD) and Alternative DSM-5 Model for Personality Disorder (AMPD) criterion A and dysfunctional personality trait (i.e., criterion B) measures, 420 Italian community-dwelling women were administered three measures of BDD (i.e., the Body Dysmorphic Disorder Questionnaire, the Body Dysmorphic Disorder-Dimensional Scale, and the Appearance Anxiety Inventory), as well as the Level of Personality Functioning Scale-Brief Form (LPFS-BF) and the Personality Inventory for DSM-5-Short Form (PID-5-SF). The three BDD measures showed substantial convergent validity correlations and could be reliably cumulated to obtain the BDD Cumulative Index (BDDCI). Several significant, nonnegligible correlations were observed between the BDDCI as well as the LPFS-BF scale scores and PID-5-SF personality trait scale scores. Relative importance weight analysis results showed that LPFS-BF scale scores and PID-5-SF trait scale scores were substantial predictors of the BDDCI scores (R = 0.42, f = 0.72). In particular, AMPD criterion A impairment in self-functioning and AMPD criterion B depressivity, anhedonia, perseveration, separation insecurity, and cognitive and perceptual dysregulation were core components of the dysfunctional personality profile associated with BDD.
