Abstract: Two multilevel meta-analyses, consisting of 10 studies and 33 effect sizes (N=796 subjects) and 6 studies and 22 effect sizes (N=1179 subjects) were conducted to examine the effects of the EQUIP intervention on the level of sociomoral development and recidivism, respectively; moderating effects of participant, program, and study characteristics were also examined. A significant overall effect on sociomoral development was found (d=.27). The effect of EQUIP on sociomoral development was moderated by the sample size: studies with a larger sample size had smaller effect sizes. For recidivism, a non-significant overall effect size (d=.13) was attributable to strong moderator effects by gender (a significant effect for girls of d=.55), year of publication (older studies yielded smaller effect sizes), ethnicity (smaller effects in non-Caucasians), and especially region, indicating that studies conducted in the USA (showing high treatment integrity) were more effective (d=.32) than studies conducted outside the USA (showing low or negligible treatment integrity, d=−.31). These results suggest the importance of considering potential effects of study, participant characteristics, and program integrity when delivering EQUIP.
