MoodGYM is a cognitive behavioural therapy (CBT) based intervention designed to prevent and treat depression. MoodGYM aims to help to identify and overcome problem emotions and to develop good coping skills. The program consists of five modules each taking 20- to 40-minutes to complete, which are completed in order. The modules teach about factors impacting on mood and how to effect change. The course teaches how to identify "warpy" thoughts, develop problem-solving skills, and learn to cope better with life events. The modules are completed at the user's own pace and through quizzes and exercises, feedback is given about  mood and what the results mean.

Outcome Summary:

Extensive investigations of MoodGYM provide evidence that it can be effective in reducing symptoms of depression in controlled trials and in real world settings. A meta-analysis carried out in 2017 found the program to be effective in adult populations based on 11 studies for depression symptoms at post-intervention with a small effect size (g = 0.36., 95% CI 0.17 – 0.56) and high heterogeneity (I2 = 78%) (18). Removing the lowest quality studies had little effect on these results, and the results were not influenced by the type of setting (clinical vs non-clinical) or whether the trials were conducted by researchers who had also been involved in the development of the program. 

MoodGYM has been evaluated in 13 studies that meet Beacon's criteria for an RCT. Out of these, MoodGYM performed significantly better than the control group in four studies (3, 13, 22, 28).   The effects of MoodGYM in reducing symptoms of depression have been shown to persist at 6 and 12-months post-test (e.g., 8). There were mixed results for the nine remaining studies.

In three studies (6 ,9 ,11), MoodGYM was trialled with Australian high school students and was shown to reduce symptoms of depression in males (d = 0.27-0.43). In adolescent girls, MoodGYM produced a significantly faster rate of decline in depressive symptoms compared to a control condition, with a moderate effect size of d = 0.46 evident 20 weeks after the intervention. Girls with high depression scores prior to completing MoodGYM showed the strongest benefits on self-reported depression at follow-up, with a large effect size of d = 0.92. However, a study of MoodGYM with high school students in Norway found no significant difference in depression symptoms for the intervention compared to a control (26).

Three small RCTs of the use of MoodGYM with university students in Australia (12, 14, 29), found that relative to controls, there was no significant difference in depressive symptoms for MoodGYM users (although the MoodGYM program significantly improved anxiety symptoms). There was also no significant different found for depression in an RCT conducted in a clinical setting in Ireland (25), although there was a significant reduction in general psychological distress in participants. A workplace-based RCT of MoodGYM compared to psycho-educational material also found no significant difference in depression for MoodGYM users (27).

The effects of MoodGYM on depression symptoms are better for those who complete more of the course (6). The addition of therapist support, either face to face or via telephone, has been shown to improve completion rates and outcomes (20). The program has also seen positive results on depressive symptoms when used in combination with BluePages, a depression information site (3).
