Personality profiles in substance use disorders: Do they differ in clinical symptomatology, personality disorders and coping?

© 2018 Elsevier Ltd We explored whether it is possible to establish subgroups of patients with a substance use disorder (SUD) based on differences in Behavioral Activation System Reactivity (BAS), Behavioral Inhibition System Reactivity (BIS) and Effortful control (EC). Further, we investigated if the identified subgroups differ on clinical symptoms, personality disorders and coping styles. Computerized self-report questionnaires were administered to 712 adult patients admitted to a specialized inpatient treatment program for SUDs. Based on cluster analysis we found three clusters: a “Resilient”, an “Anxious” and a “Reward Sensitive” cluster. The Anxious cluster showed the highest scores on each of the clinical symptoms, the Resilient cluster consistently displayed the lowest scores, and the Reward-Sensitive cluster generally scored in-between.status: publishe
