ADAPT-ITT framework (Assessment, Decision, Administration, Production, Topical Experts, Integration, Training, and Testing

Assessment	Provided relapse prevention written materials to the project coinvestigators with the assignment to read and mark up the materials. Completing this task, investigators attended a 2-hour web conference where they: (1) received a presentation on relapse prevention among substance using populations, and (2) provided brief verbal summaries of their assigned reading materials to one another in the group.
Decision	Following the presentation and summaries, the web conference involved roundtable discussion, eliciting suggestions regarding needed intervention components.
Administration	Meeting participants provided specific recommendations on how to incorporate the identified components into the PN manual.
Production	Concluding the web conference, handwritten notes and comments recorded during the Decision phase were requested by the project leader. Once received, this information and the identified relapse prevention content was infused into the PN intervention.
Topical Experts	Adapted intervention sessions materials were circulated to the project coinvestigators for review and comment.
Integration	Comments and edits from the review of the sessions were returned for finalization and incorporation into the intervention manual.
Training	The project leader authored instructions for the adapted sessions on how navigators are to become familiar and proficient in the relapse prevention content, and how navigators are trained.
Testing	Navigators trianed in the relpase prevention infused study materials deliver this materials througout the study.
