CAU care-as-usual, ESTIA-TS efficacy of social skills training in autism—training specific, SSRS-P social skills rating scale-parents, (COO cooperation, ASS assertion, sco self-control, RES responsibility), SST social skills training, SST–PTI social skills training—parent and teacher involvement, Vineland Vineland Adaptive Behavior Scales (SOC socialization),—means that this effect was not included in the model, because it was not hypothesized and appeared nonsignificant when including the effect
