Abstract

Background: Dimensional models of personality and personality disorders (PDs) have been widely investigated among individuals with alcohol use disorders (AUD). Nevertheless, DSM-5 maladaptive personality domains showed mixed associations with AUD. Furthermore, no studies have explored the role of DSM-5 maladaptive personality domains on the comorbidity between AUD and different PDs. Objective(s): This study aims at investigating whether DSM-5 maladaptive personality dimensions could differentiate individuals with AUD from normative and healthy controls (HCs) subjects. The study also investigated relationships between these personality dimensions and AUD clinical features (i.e. onset, severity of concurrent substance use disorders), as well as their role in accounting for the comorbidity between AUD and PDs. Methods: This study administered the personality inventory for DSM-5 (PID-5) to 99 treatment-seeking individuals (male 68.8%; female 31.2%; age: 48.12 (14.32)) with AUD (41 AUD only; 58 AUD with PDs), comparing the participants’ levels of PID-5 domains with normative data and the data from a HC sample (N = 40; male 50%; female 50%; age: 48.12 (14.32)). Results: Disinhibition and negative affectivity were relevant maladaptive personality dimensions of AUD, even when controlling for the impact of PD diagnoses. Disinhibition and negative affectivity were associated to the onset of AUD and the severity of concurrent substance use disorders. The co-occurrence of AUD and PDs is related to other two domains, namely antagonism and detachment. Conclusions: AUD is a complex psychopathological disorder in which both externalizing and internalizing aspects determine relevant clinical features.
