The 25 sites will be divided into three cohorts (n=8,8,9). Each cohort will begin over three successive six-month blocks beginning in early 2016. Within each cohort, sites will be randomized to receive either facilitated or standard implementation. Facilitated Implementation sites will receive one year of support based on the i-PARIHS implementation model which includes training, implementation planning, ongoing external facilitation, feedback and consultation. Standard Implementation sites will receive written guidance and limited consultation by the investigators' team. The investigators will compare the groups on 1) the percent of their target population that actually received PS services; 2) ratings on PS workload productivity including ; 3) Peer Implementation and Services scores; 4) assessment of Veteran's change over time on the outcome variables of satisfaction, activation, and functioning ; 5) qualitative analysis of how well PSs were deployed and their impact.
