OBJECTIVE: Obsessive-compulsive disorder (OCD) and substance use disorders (SUDs) are serious psychiatric conditions that frequently co-occur, complicating diagnosis and treatment. However, data on their comorbidity in Middle Eastern populations remains limited. This study investigated the prevalence of OCD and its psychiatric comorbidities among inpatient substance users in Iranian psychiatric hospitals. METHODS: This cross-sectional study included 250 inpatients diagnosed with SUDs in Tehran between 2019 and 2022. Demographic, clinical, and psychiatric data were extracted from medical records. Logistic regression was used to examine associations between OCD and demographic/clinical variables. RESULTS: .143). CONCLUSION: OCD is relatively prevalent among individuals with SUDs and is frequently accompanied by other psychiatric disorders. Although no demographic predictors were statistically significant, these findings emphasize the need for routine OCD screening in addiction treatment settings to improve integrated care strategies.
