Attendance and Program Satisfaction
Of the 56 participants who consented to participate across both treatment conditions, 82.1% of veterans attended at least one treatment session and 44.6% completed all seven sessions, with the average being 4.73 sessions attended across conditions. Regarding surveys, 3 (5.4%) veterans did not complete the baseline survey and 15 did not complete the follow-up survey (26.8%). Of the 56 who consented, 40 (71.43%) completed all study components (i.e., completed both baseline and follow-up surveys and attended at least one treatment session) and were considered the analytic sample for analyses (MMMI n = 21; ESn = 19). There were no significant statistical differences on demographic characteristics (e.g., age, years in military, gender) and baseline scores on outcome variables between the analytic group (n = 40) and those not in the analytic group (n = 16).
Among the 40 veterans in the analytic sample, most participants identified as being White (77.5%), were men (62.5%), and reported a service-connected disability (82.5%). They reported a mean age of 42.70 years (Median = 41.00, SD = 10.07) and on average served 13.01 years in the military (Median = 8.00, SD = 9.57). The Army (55.0%) and Navy (12.5%) were the most represented branches. Within our analytic sample, there were no significant differences in the average number of sessions attended between the MMMI (M = 6.10,SD = 1.48) and the ES (M = 6.11, SD = 1.37) groups.
In Table 1, we provide information on treatment satisfaction (i.e., reactions, attitudes/learning/knowledge, behavior, return on investment, and total score on satisfaction) by treatment condition (MMMI n = 21; ES n = 19). Regarding specific satisfaction questions, the MMMI condition reported significantly higher confidence in their ability to apply the program content to their daily live since the training (Cohen’s D = 1.19), reported more often having put the things they have learned into practice (Cohen’s D = 0.83), and reported that they benefitted more from the program (Cohen’s D = 0.78). Regarding subscales, the MMMI condition reported higher satisfaction in behavior (Cohen’s D = 0.67) and return on investment (Cohen’s D = 0.78). No other statistically significant program satisfaction differences were noted.
