Power analysis for a proposed group randomized control trial (GRCT) on the Road to Mental Readiness (R2MP) program / Aihua Liu, Deniz Fikretoglu.: D68-2/68-2014E-PDF
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), a robust power analysis was conducted to determine the sample size that would be required for the GRCT on R2MR. Intraclass correlation coefficients (ICCs) were also calculated 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 the 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 the outcomes. It is therefore recommended that data be collected lasting up to one and a half years for the proposed GRCT on R2MR.
