RESUMO
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.

To evaluate the usefulness of the DSM-5 maladaptive personality domains in explaining the similarities and differences among four disorders included in the obsessive-compulsive spectrum, 428 Italian community-dwelling women (mean age = 31.96 years, SD = 12.30 years) were administered the Obsessive-Compulsive Spectrum Disorder Scales and the Personality Inventory for DSM-5-Short Form as part of an ongoing online survey on women's health. Multiple Indicators Multiple Causes (MIMIC) confirmatory bifactor analysis results showed that the OCSD general factor (i.e., obsessive-compulsive spectrum factor) was positively associated with Negative Affectivity, whereas Body Dysmorphic Disorder (BDD), Hoarding Disorder (HD), and Skin-Picking Disorder (SPD) specific factors showed significant and substantial differential relationships with dysfunctional personality domains. Specifically, BDD was positively associated with Negative Affectivity, Detachment and Psychoticism domains; HD was associated with high Negative Affectivity and Psychoticism; and SPD was associated with Detachment. © 2020 John Wiley & Sons, Ltd.
