Abstract

Objective: Individuals with substance use disorder are not homogeneous as we might regard. Thus, this study was conducted to present a novel classification of substance use disorder based on temperament, addiction severity, and negative emotions. Method: In this correlation study, Temperament and Character Inventory, Addiction Severity Index, Aggression Subscale of MMPI-2, Depression, Anxiety, Stress Scale, Emotional Schema Questionnaire, and Psychosocial Checklist were used for data collection. Results: The cluster analysis of 324 individuals with substance use disorder explored 4 subtypes. Subgroups were named based on the main features as emotionally distressed, constitutional, nonconformist, and impulsive. Significant differences were found among groups in emotional schemas, history of mental disorder in the family, rate of relapse, and history of imprisonment. Conclusion: It seemed that temperament dimensions, addiction severity, and negative emotional states were valid components in classifying individuals with substance use disorder. © 2018 Tehran University of Medical Sciences.
