To determine program feasibility, we report attendance for all consented
participants. We then report attendance and program satisfaction by
group for the analytic sample (MMMI n = 21; ES n = 19).
Next, we report results of a series of repeated measures ANCOVA models
in SPSS 28 for the analytic sample, to determine if there were
significant pre-to-post intervention changes as determined by effect
sizes in moral injury outcomes and whether these changes differed by
group (i.e., condition x time interaction effects). Given the pilot
nature of the project and sample size, the main focus was on effect size
estimates (i.e., partial eta squares). The magnitude of effects was
interpreted based on guidelines for small (η2 = .01), medium (η2 = .06),
and large (η2 = .14) effects (Richardson, 2011).
