As an introduction to the major mental disorders, this course aims to prepare students for working with clients with serious mental health problems in private, institutional and community settings. The course focuses on a biopsychosocial and spiritual understanding of mental health and well-being. Utilizing the holistic approach to mental health, this course will explore classifications and symptomatology of the more severe and chronic forms of psychiatric disorder, their etiology and nature, and their diagnosis. The Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) will be used as a reference point. The students will also be introduced to the critical influence of culture, class, race and ethnicity, religion, and social values of the individual, family, group, and social institutions in the assessment of mental health disorders. The course will critically review current classification systems and major theories regarding the nature of mental disorders, their diagnoses and etiologies, the treatment approaches available to help people in their recovery, and culturally relevant variables. As a result, the students will be able to critically utilize terminology and concepts in the DSM-5 and identify best practices in psychotherapy practice.
