CBCL child behavior check list, EXT externalizing behavior problems, INT internalizing behavior problems, SSRS social skills rating scale, TRF Teacher Report Form
Parent reports DG N = 115, and EG N = 44. Teacher reports DG N = 103, and EG N = 41
aA higher score indicates more social skills. Children’s behavior pre-treatment scores were used as covariates in all models. (All were significant at p < .001)
