Effectiveness of MH-Guru, a brief online mental health program for the workplace: A randomised controlled trial

•First RCT in the workplace to demonstrate the effectiveness of an online intervention for anxiety and depression in staff without health credentials.•The intervention (MH-Guru) was associated with reductions in stigma and improvements in literacy for depression and anxiety, sustained over 6 months.•Intentions to seek help from the Internet were greater at 6 months among those receiving the workplace intervention.

BackgroundDepression and anxiety interfere with an individual's quality of life and result in substantial economic costs to the workplace through lost productivity. The internet offers an unparalleled opportunity for the large scale, cost-effective delivery of mental health awareness and destigmatisation programs in the workplace. However, to date high quality assessments of the effectiveness of such workplace programs have been confined to health professional settings. The current study reports the effectiveness of Mental Health Guru (MH-Guru), a two-module online mental health workplace induction program.MethodsA total of 507 employees from a large multi-departmental government workplace were randomised to a 2-week online depression and anxiety educational program (Mental Health Guru; MH-Guru), or a Wait List Control condition. Participants completed online surveys at baseline, 1 week post-intervention and at 6-month follow-up. Primary outcome measures included depression and anxiety literacy, personal stigma about depression and anxiety, and help seeking intentions for anxiety and depression at post-test. Secondary measures included help-seeking attitudes and self-reported help seeking behaviour. Satisfaction measures were also collected.ResultsDropout at post intervention was 26.7% and 21.0% for the MH-Guru and Control conditions respectively. Relative to Control, MH-Guru participants showed significantly greater improvements in depression and anxiety literacy at post intervention. Between group standardized effect sizes at post-test and 6-months were 0.78 and 0.81 for depression literacy and 0.80 and 0.79 for anxiety literacy. Compared to the Control participants, the MH-Guru group also showed significantly greater reductions in depression and anxiety personal stigma. Between group effect sizes in stigma for depression were − 0.56 and − 0.47 at post-test and 6-months respectively and − 0.42 at both time points for anxiety. The MH-Guru intervention was not associated with a differentially greater increase in anxiety or depression help-seeking intentions or improvement in help seeking attitudes compared to the Control group. However, self-reported help-seeking behaviour was significantly greater in the MH-Guru group at post-test. In addition, the MH-Guru group showed greater intentions to seek help for depression from the Internet at 6-month follow-up. Satisfaction items suggested that the program was acceptable to employees.ConclusionsBrief online programs such as MH-Guru have the potential to play an important role in increasing mental health awareness and decreasing stigmatizing attitudes in the workplace, and by extension the general community.
