In summary, with respect to other meta-analyses of RCTs of
SST, our findings are quite consistent with those of Pfammatter et
al. (2006), who found large effects on skill measures more proximal
to the locus of SST interventions, and smaller, but significant,
effects on more distal measures of social functioning and general
psychopathology. Our findings are discrepant from the largely
negative results reported by Pilling et al. (2002). The larger number
of studies included in the current analysis (22 vs. 9), coupled
with Pilling et al.’s grouping of outcome measures that varied with
respect to their proximity to the locus of SST treatments, most
likely accounts for this difference.
