Play is often used in interventions to improve social outcomes for children with autism spectrum disorders (ASD). Play is a primary occupation of childhood and, therefore, an important outcome of intervention. The Ultimate Guide to Play, Language and Friendship (PLF) is a peer-mediated intervention for 6–11-year-old children with ASD. A total of 68 dyads were randomized to either a 10-week treatment first or waitlist control group. Results revealed a significant moderate intervention effect from pre- to post-intervention, which was maintained to the 3-month follow-up clinic session and generalized to the home environment. The findings support that the PLF intervention can be used to positively improve play in 6–11-year-old children with ASD.
