Typical Sequence of Sessions for Project ImPACT (Ingersoll & Dvortcsak, 2010)

Session 1	Therapists administer the intake assessments. Overview and goals of the program, intervention techniques (interactive and directive), and social-communication are discussed.
Session 2	Therapists begin with teaching the interactive techniques. They first discuss how to set up the home environment for practicing intervention techniques (e.g., scheduling predictable routines, setting up a defined space, limiting distractions, toy rotation) and following the child’s lead.
Session 3	Therapists and parents develop specific goals for the child. Topics covered include how to use animation using direct language stimulation, (e.g., self-talk and parallel talk) to make play and daily activities more interactive.
Session 4	Therapists teach parents how to model and expand their child’s language and use playful obstruction to create opportunities for communication and increase social engagement.
Session 5	Therapists teach parents how to use communicative temptations (e.g., have a desired toy in the child’s sight but out of reach) and taking turns during play.
Session 6	Therapists begin teaching the directive techniques, which require the parent to use prompting and reinforcement to increase the complexity of their child’s response.
Session 7	Therapists teach parents how to use eight specific language prompts coordinated with reinforcement to enhance their child’s expressive language.
Session 8	Therapists teach parents how to use four specific prompts coordinated with reinforcement to enhance the child’s ability to understand and follow directions.
Session 9	Therapists review previously taught interactive techniques and new directive techniques to teach the child social imitation.
Session 10	Therapists teach parents how to use six specific play prompts coordinated with reinforcement to increase the complexity of the child’s play.
Session 11	Therapists review the use of interactive and directive techniques and update developmental and behavioral child goals.
Session 12	Therapists administer the post assessments and develop a plan for continued implementation of intervention techniques.

Note. This sequence was adapted, per routine care, for the site in which the intervention was delivered for this study.
