Fundamentals of Psychological Disorders (formerly Abnormal Psychology) is an Open Education Resource written by Alexis Bridley, Ph.D. and Lee W. Daffin Jr., Ph.D. through Washington State University which tackles the difficult topic of mental disorders in 15 modules and is updated through the DSM-5-TR. After the first three foundational modules, a discussion of mental disorders ensues to include depressive, anxiety, personality, schizophrenic, eating, and obsessive-compulsive to name a few.
