Use of a Web-Based Shared Decision-Making Program: Impact on Ongoing Treatment Engagement and Antipsychotic Adherence.

Objective: The authors examined the impact of a Web-based shared decision-making application, MyCHOIS-CommonGround, on ongoing outpatient mental health treatment engagement (all users) and antipsychotic medication adherence (users with schizophrenia).

Methods: An intervention study was conducted by comparing Medicaid-enrolled MyCHOIS-CommonGround users in 12 participating mental health clinics (N=472) with propensity score-matched adults receiving services in nonparticipating clinics (N=944). Medicaid claims were used to assess ongoing treatment engagement and antipsychotic adherence (among individuals with schizophrenia) one year prior to and after entry into the cohort.
