autism interventions
The operative claimSocial-skills interventions for autistic children and youth produce small-to-moderate gains on rated and tested social skills, but improvements often reflect social KNOWLEDGE more than real-world social PERFORMANCE, generalization and maintenance across settings are weak, and effect sizes shrink under more rigorous designs and independent informants.
Contested. Social-skills interventions yield small-to-moderate gains on rated/tested skills, but it is debated whether they change real-world social performance, given weak generalization and informant effects.
A meta-analysis of 19 RCTs found medium overall effects but attributable to social knowledge (g = 1.15), not performance (g = 0.28), with limited generalization (Gates et al., 2017); an earlier meta-analysis of single-subject studies found interventions "minimally effective" (Bellini et al., 2007); an umbrella review rated the evidence only "suggestive" with few results surviving low-bias sensitivity analysis (Gosling et al., 2022); fidelity is often low (Afsharnejad et al., 2023).

Meta-analysis
Group social-skills interventions showed medium overall effects (g = 0.51), but the self-report effect was wholly attributable to gains in social KNOWLEDGE (g = 1.15), not social PERFORMANCE (g = 0.28), and may not generalize to school or self-reported behavior.
Bearing on this claim: RCT meta-analysis: gains reflect social KNOWLEDGE (g=1.15) not PERFORMANCE (g=0.28); weak generalization.

Meta-analysis
Group social-skills interventions showed large effects on parent-rated social responsiveness and moderate effects on social-skills subscales; the authors urge future trials to distinguish gains in social knowledge from social performance.
Bearing on this claim: Group SSIs: large parent-rated SRS effects; urges separating knowledge from performance.

Systematic review
Social-skills groups were supported by only "suggestive" evidence for social communication in school-aged youth; just four meta-analyses remained statistically significant in a sensitivity analysis restricted to low-detection-bias RCTs.
Bearing on this claim: Umbrella review: only "suggestive" evidence; few results survive low-bias sensitivity analysis.

The Methodological Quality and Intervention Fidelity of Randomised Controlled Trials Evaluating Social Skills Group Programs in Autistic Adolescents: A Systematic Review and Meta-analysis. Journal of Autism and Developmental Disorders.
Meta-analysis
Social-skills group programs showed an adjusted medium overall effect (g = 0.60), but most studies had medium-to-low program fidelity and high heterogeneity, leaving generalizability unclear.
Bearing on this claim: Adolescent SSGPs: medium effect (g=0.60) but low fidelity, unclear generalizability.

Meta-analysis
School-based social-skills interventions were found to be only MINIMALLY effective for children with ASD, with weak maintenance and generalization across settings.
Bearing on this claim: Single-subject meta-analysis: school-based SSIs "minimally effective"; weak maintenance/generalization.

Effects depend heavily on informant (large self/parent-report, near-null teacher-report); generalization and maintenance are weak; fidelity and publication bias limit conclusions; and outcomes are often context-bound.
