This course is designed to give students an in-depth examination of the significant forms of psychopathology. Relevant psychological theories, research, and cultural perspectives regarding the phenomenology and causes of psychological disorders are included. As outlined in the DSM-5 and DSM-5-TR, major psychological disorders are examined, and treatment options are reviewed with an emphasis on the client/patient's experience of psychopathology. Differential diagnoses of clinical case studies, including those with comorbidities and ambiguities, are scrutinized, analyzed, and criticized.
