A total of 230 providers will be recruited (RR n=115; IMR n=115), for a target of 200, oversampling due to attrition. Each provider will recruit two clients to participate (RR n=230; IMR n=230), for a target of 400 total, oversampling due to attrition. Investigators will use mixed methods to assess provider knowledge, behaviors, and relationships related to PCRP via surveys, standardized instruments, interviews, and a Social Network Analysis. Client PCRP knowledge, recovery outcomes, treatment engagement, and provider/client relationship will be assessed via surveys, standardized instruments, and client administrative data. Investigators will also conduct administrator interviews.
