This observational, cross-sectional case-control study evaluates obsessive-compulsive symptoms among adults with substance use disorder compared with a demographically similar control group without substance use disorder. Patients aged 18-50 years attending the addiction management inpatient and outpatient services at Assiut University Hospital, and healthy controls recruited from relatives, friends, and hospital staff, will complete structured clinical interviews, the Yale-Brown Obsessive-Compulsive Scale, and other standardized scales for psychiatric symptoms, cognition, and quality of life. The main objective is to estimate the prevalence and severity of obsessive-compulsive symptoms in substance use disorder and examine their associations with sociodemographic and clinical factors, addiction severity, and quality of life in the recovery stage.

Substance use disorders and obsessive-compulsive disorder are chronic, relapsing conditions that share underlying neurobiological mechanisms related to compulsivity and have substantial impact on functioning and quality of life. Clinical experience and prior research suggest that obsessive-compulsive symptoms may be under-recognized among individuals with substance use disorders, where they can worsen psychiatric comorbidity, complicate treatment, and impair recovery. The current study will recruit 102 adults aged 18-50 years, including 51 patients with a diagnosed substance use disorder (single or polysubstance) from the inpatient and outpatient addiction management unit at the Neuropsychiatry Department, Assiut University Hospital, and 51 control participants without substance use disorder drawn from relatives, friends, and hospital workers. All participants must be in a non-intoxicated, non-withdrawal state and able to provide informed consent; individuals with severe psychiatric disorders (such as schizophrenia, bipolar disorder, major depressive disorder with severe features, or anorexia nervosa), severe medical illness, or marked cognitive impairment will be excluded. Data collection will include a structured sociodemographic and clinical sheet, brief psychiatric interview, and administration of validated instruments such as the Yale-Brown Obsessive-Compulsive Scale, Obsessive Compulsive Drug Use Scale, Symptom Checklist-90-R, Montreal Cognitive Assessment, and Hamilton scales for anxiety and depression, along with urine analysis for substances. The primary objective is to assess the correlation between obsessive-compulsive symptoms in patients with substance use disorder and both symptom severity and quality of life, while secondary objectives address compulsive aspects of addiction, craving in patients with obsessive-compulsive symptoms, and potential implications for management strategies.
