The efficacy of a Social Skills Group Intervention for improving social behaviors in children with High Functioning Autism Spectrum disorders.

Lancioni et al. (2011) ran a randomized trial with kids who have high-functioning autism. Half joined the S.S.GRIN-HFA group. The other half joined a generic social-skills club.

Both groups met after school for the same number of weeks. Trained staff taught conversation rules, friendship skills, and handling teasing. Parents filled out forms before and after.

Kids in S.S.GRIN-HFA mastered more social concepts than the generic group. Parents also felt surer that their child could make and keep friends.

The gains showed up on both direct tests and parent checklists.

Afsharnejad et al. (2024) pooled every social-skills group study they could find. After fixing for publication bias, they saw no overall benefit. This seems to clash with Lancioni et al. (2011), but the review mixes short and long programs, different age bands, and weak measures. S.S.GRIN-HFA used a tight manual and parent-coached homework, which may explain its edge.

Poppes et al. (2010) and Wuang et al. (2012) tested an earlier program called SCI. Like S.S.GRIN-HFA, they saw parent-reported gains, but they had no control group. E et al. added random assignment, giving us cleaner proof.

Arnardóttir et al. (2025) trimmed the model down to nine sessions in the FEST pilot. They still found small gains, showing the idea holds even when you shrink the dose.

If you run social-skills groups in school or clinic, swap any loose lesson plan for a scripted, parent-linked package like S.S.GRIN-HFA. The structure, clear rules, and home practice may be why it beat the generic club. Track both skill tests and parent confidence; they move together.
