Abstract
This study compared immediate and 4-month outcomes among adolescents with autism spectrum disorder randomly assigned to the PEERS curriculum (n = 10), a peer mediated PEERS curriculum (n = 12), or a delayed treatment control group (n = 12). Findings suggest a modest advantage in social skills knowledge and social functioning for participants in the peer-mediated PEERS curriculum relative to Traditional PEERS, and gains in social skills knowledge, social functioning, and reductions in loneliness were maintained in one or both treatment groups at a 4-month follow-up. Typically developing peer mentors (n = 16) showed improvements in social skills knowledge and marginal improvements in autism knowledge and loneliness. Future research with a larger sample and objective outcome measures is needed.

Change history
Notes
A non-parametric Kruskal–Wallis test indicated a marginally significant effect of study group on R-UCLA changes scores from time 1 to time 2 [H (2) = 5.38, p = .07].
When the extreme outlier was included, there was not a significant increase in autism knowledge [t (15)= − 0.83, p = .42, d = 0.21]. This participant demonstrated a change score of − 10 on the AKQ; the next lowest change score was − 3. The clinicians reported that this teen arrived late to the final session and seemed to be rushing to complete the post assessments.
