Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study will test the effectiveness of a brief, internet-based, workplace mental health program- Mental Health Guru - using a randomised controlled trial design.

The Mental Health Guru program is an online educational program currently comprising two modules: 1) depression and 2) generalised anxiety disorder each of which comprises information about mental illness and the myths associated with it, personalised feedback and consumer videos. Participants randomly allocated to the intervention condition will be asked to complete one module per week, with each module requiring approximately 30 minutes to complete. The program can be completed via home or work computers.

Program usage data will be captured from the technology systems including program module access, number of site visits and an estimate of length of exposure derived from log analysis.

Wait-list

Individuals randomised to the wait-list control condition will receive access to the intervention program directly after completion of the 6-month assessment. If the participant has not accessed the 6 month assessment within one month, it will be closed. If a participant logs in after this time they will be provided with access to the intervention program. The intervention program will be available for a minimum period of 3-months from the date of the 6-month assessment notification.

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be recruited from organisations that have provided informed written consent. The trial will be advertised to employees via employer emails and other advertisement materials. All advertisement materials will contain a url address for the study, which provides detailed information about the scope, nature and potential outcomes of the trial. If they choose to proceed, employees will then be required to answer a series of questions to provide their informed consent. Only after this process is completed will the employee be enrolled into the trial and asked to begin the baseline assessment. After completion of the baseline assessment, participants will be randomised to the intervention or control condition by computer generated random number assignment and notified of their allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be stratified by gender and by management/ general staff status, and will use block randomisation with randomly generated block sizes.
Masking / blinding

Efficacy
Statistical methods / analysis
Analysis will be undertaken according to intention-to-treat principles, comparing outcomes from all participants allocated to the intervention group (regardless of whether they complete the intervention or not) with all participants in the wait-list control group. Emphasis in the statistical analyses will be on differences between the intervention and control group in terms of changes across time (i.e., baseline to post-intervention, baseline to 6-month follow-up, and post-intervention to 6-month follow-up). We will examine these differences using mixed models analyses. Additional analyses will be performed to compare outcomes for completers. Missing data patterns will be examined and analysis will be undertaken to identify any baseline differences between completers and non-completers.

For power calculations the effect sizes achieved for the primary outcomes of mental health literacy, stigma and help-seeking in the MH-Guru pilot trial were considered. Based on a power of 0.80, an alpha of 0.05, and an expected drop out rate of approximately 60% (based on the MH-Guru pilot trial), we aim to assign 440 employees to each condition to show an effect size of 0.30 (the smallest effect size achieved for a primary outcome in the MH-Guru pilot trial). Based on this determination the total sample size needed is 880.
