This book offers a culturally and religiously significant perspective on the assessment of Muslim individuals experiencing mental health issues. The belief that jinn can cause mental health problems in humans is widespread among Muslim societies. However, this belief is often overlooked in psychiatric treatment processes. The book addresses the nature of such beliefs, their relationship with mental health, and their importance in the treatment process. Furthermore, it emphasizes that mental disorders are influenced by multiple factors and the importance of taking these factors into account. In addition to being an important resource for psychologists, counselors, and mental health professionals, this book is also of interest to students and academics working in the field of health sciences.
