10-Unique Cases: A Case Book on Obsessive–Compulsive Disorder for Clinical Psychologists is a clinically oriented, practice-focused volume designed to strengthen the application of evidence-based psychological principles in the assessment and treatment of Obsessive–Compulsive Disorder (OCD). Recognizing OCD as a heterogeneous and multidimensional condition, this book presents ten carefully selected and uniquely conceptualized clinical cases that reflect the diversity, complexity, and evolving phenomenology encountered in real-world clinical settings. Each case is systematically structured to mirror the actual workflow of professional clinical practice. The chapters include detailed patient histories, comprehensive psychodiagnostic assessments, differential and final diagnostic considerations, therapy goals, and individualized therapeutic formulations. Special emphasis is placed on the rationale for diagnosis, case conceptualization grounded in contemporary psychological models, and the selection of intervention strategies consistent with current scientific evidence. Therapy modules, outcome evaluations, and six-month follow-up reports are incorporated to demonstrate treatment progression, therapeutic challenges, and long-term clinical outcomes.
The primary aim of this book is to bridge the gap between theoretical knowledge and applied clinical work. By presenting richly detailed case material, it seeks to enhance diagnostic clarity, promote formulation-driven intervention, and foster reflective clinical reasoning among practicing and trainee clinical psychologists. Several cases highlight atypical or less frequently documented presentations of OCD, thereby contributing to the growing clinical literature on rare, nuanced, or culturally influenced manifestations of the disorder. This volume has been written with strict adherence to ethical principles governing clinical psychology.
