Abstract:

The Road to Mental Readiness R2MR program is the largest mental health training initiative in the Canadian Armed Forces CAF. As part of an effort to test the efficacy of R2MR at Basic Military Qualification BMQ with a group randomized control trial GRCT, we conducted a robust power analysis to determine the sample size that would be required for the GRCT on R2MR. We also calculated intraclass correlation coefficients ICCs for the outcomes that will be measured in the GRCT, a necessary preliminary step for the power analysis. Data from the calculation of the ICCs were extracted from multiple programs of ongoing research with the Non-Commissioned Member NCM recruits, the intended target population for the GRCT. The results of our analyses suggest that data collected over the course of one full fiscal year will yield sufficient statistical power to detect expected effect sizes for most but not all of our outcomes. We therefore recommend data collection lasting up to one and a half years for the proposed GRCT on R2MR.
