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 = 132, and EG N = 49. Teacher reports DG N = 133, and EG N = 48
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)
