Peer training protocol

Protocol	Description
Introduce topic	The interventionist defined the target behavior and provided a verbal example using Table 2 as a guide.
Live model	The interventionist engaged in the target behavior/s (e.g., while playing Monopoly, the interventionist initiated sharing by moving a game piece on the board and then saying something like, “Yay! I landed on Go and can collect $200!”).
Video model	Interventionist played the video model of the target behavior.
Role play	The interventionist and TD peer played a game for 5 min. The interventionist instructed the peer to demonstrate the target behaviors with the interventionist playing the role of the child with ASD (e.g., for prompting, the interventionist did not attend and looked away so the peer could practice tapping the interventionist acting as the child with ASD on the shoulder and reminding him/her it was his/her turn). For each turn, the interventionist provided an opportunity for the peer to engage in the target behavior(s). If the peer did not engage in the target behavior, the interventionist quickly modeled the appropriate behavior and provided another opportunity for the peer to practice the appropriate target behavior.
Feedback	The interventionist provided behavior-specific praise for target behaviors the peer demonstrated well and provided corrective feedback for any missed opportunities to engage in the target behavior/s or other ways to improve the target behavior/s.
