MoodGYM is a web-based program that offers education and skills-practice for users struggling with common symptoms of depression or anxiety. Using principles of Cognitive Behavioral Therapy (CBT), MoodGYM encourages users to learn and practice new ways of thinking and reacting to daily situations. This can begin to change problematic or irrational thinking that may be contributing to a mental illness. MoodGYM consists of five interactive modules with exercises and quizzes.
