Abstract :
Obsessive-Compulsive Disorder (OCD) is a chronic and debilitating psychiatric disorder characterized by recurrent intrusive thoughts and repetitive compulsive behaviors that significantly impair emotional, social, occupational, and interpersonal functioning. The present case study explored the clinical presentation, assessment, case conceptualization, diagnosis, treatment planning, and therapeutic outcome of a 38-year-old married female diagnosed with obsessive-compulsive disorder with anxious distress. The patient presented with contamination-related obsessions, excessive cleaning rituals, severe anxiety, emotional exhaustion, sleep disturbance, and marked psychosocial impairment. A comprehensive multimethod psychological assessment was conducted using standardized psychometric instruments and projective techniques to evaluate symptom severity, emotional functioning, personality dynamics, and cognitive status. The case was conceptualized using Cognitive Behavioral Theory and the Cognitive Model of OCD, emphasizing dysfunctional beliefs including inflated responsibility, perfectionism, intolerance of uncertainty, and catastrophic thinking. A structured Cognitive Behavioral Therapy (CBT) intervention combined with Exposure and Response Prevention (ERP), mindfulness strategies, psychoeducation, and family interventions was implemented over twelve sessions. Significant reductions in obsessive-compulsive symptoms, anxiety, compulsive rituals, and functional impairment were observed following treatment. The findings emphasized the effectiveness of evidence-based psychological interventions in improving emotional regulation, distress tolerance, insight, and psychosocial functioning.
