Over all these meta-analyses involving social skills programs, the effects are stronger on enhancing peer relations (d = 0.80 to d = 0.90) and social outcomes (about d = 0.5 to d = 0.6); lower when the students are initially identified as social problems (d = 0.20); and lowest when academic achievement is the outcome of the social-skill programs (d = 0.10 to d = 0.20).
