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.
