ABSTRACT
Introduction: Substance use disorder (SUD) is increasingly prevalent in the world and negatively affects
individuals and society in many areas. This study aimed to identify sociodemographic, clinical, and
addiction-related factors associated with aggression among individuals with substance use disorder.
Method: The study included 195 individuals who completed 14-day detox treatment. Participants were
administered the sociodemographic data form, Addiction Profile Index (API) and clinical form (API-C) and
Buss Perry Aggression Questionnaire (BPAQ).
Results: In our study, it was found that the high aggression group started substance use at an earlier age
than the low aggression group, was younger, single and had a higher rate of unemployed history. The
addiction profile was found to be more severe in the high aggression group, with a higher rate of suicide
attempts and multiple substance use history. Among the clinical variables, anger control insufficiency,
multiple substance use, and employment history were found to be associated with total aggression.
Conclusions: Our study shows that there are many different addiction dimensions and sociodemographic characteristics that affect aggression in SUD patients. Identifying these risk factors may help
clinicians tailor treatment approaches and reduce aggression-related complications in individuals with
substance use disorder.
