Background: Posttraumatic stress disorder (PTSD) is a stress disorder, whose prevalence was 2-15%. PTSD is associated with mood, anxiety, personality and substance use disorders (SUD). The substance user patients with PTSD have more problems, and severity of symptoms is more than non-substance users with PTSD patients. These patients may be nervous, aggressive, and restless and their function will be affected in many aspects. The aim of this study was to determine the relationship between aggression levels and substances use among PTSD patients.

Methods: Among patients with PTSD referred to Kermanshah Farabi Hospital in 2011,182 cases were selected and their aggression levels were assessed by Buss & Perry Aggression Questionnaire. The aggression levels in PTSD patients with and without SUD were compared.

Result: The highest frequencies were in middle-aged (81.1%), males (91.8%), married (77.5%) and poor economic status (63.2%) patients. Substances using was higher among married patients and the most abused substances was opium. Substances consumption was higher among patients with lower socioeconomic status and opium and amphetamines were the most abused substance. Most PTSD types were related to after-war events (70.3%). Mean of total aggression was higher in SUD. Rate of total aggression was higher in patients using opium.

Conclusion: Compared to those without PTSD, individuals with this disorder are more likely to have aggression. Patients with concurrent PTSD and SUD suffer from more severe complaints and show worse treatment outcomes compared with patients with either disorder alone.
