Purpose of Present Study
We had several aims for this initial evaluation of MMMI. The first aim of this study was to evaluate the feasibility and acceptability of MMMI. Second, given the strong focus of MMMI for the reduction of moral injury symptoms, we explored whether there was initial evidence for the effectiveness MMMI in reducing moral injury symptoms as compared to an equally intensive intervention focusing on psychoeducation. Notwithstanding the preliminary nature of this study, we hypothesized that veterans in the MMMI group would report greater reductions in moral injury symptoms compared with veterans randomized to an equivalent seven-week, web-based live, instructor facilitated educational support (ES) condition. Given the small clinical trial, we emphasized the statistical significance and magnitude of effect size estimates (i.e., partial eta-squares) of treatment effects on outcomes.
