Telementoring to Strengthen Child and Youth Mental Health Care Capacity in Primary Care Providers: Session Duration and Learning Outcomes.

Primary care providers (PCPs) report insufficient capacity for child and youth mental health care (CYMH). The telementoring program Project ECHO (Extension for Community Healthcare Outcomes) can build capacity, but 75- to 120-minute sessions are a participation barrier. Using a Lean health care paradigm, we designed a 60-minute session, and compared self-reported CYMH capacity strengthening (10 constructs) and satisfaction between 60- and 90-minute sessions.
