Exploratory subgroup analyses of the following possible interactions will be undertaken to assess whether the effect of sociotherapy intervention is modified by the prespecified covariates: survivors, perpetrators, and youth. These subgroup analyses will be performed by adding the interaction term between the allocated group and the subgroup variable into the generalized effect model. Given the limited power to detect treatment–subgroup interactions, analyses of the results will be interpreted with caution. All subgroups will be analyzed using the intention to treat the population. Wherever applicable, to compensate for multiple comparisons, this study will employ a Bonferroni correction factor.
