RecruitingClinical trialTeen Helpline Motivational Interviewing StudyThe proposed study will establish a foundation for research within peer-delivered helplines for teens. It aims to evaluate the impact of a Motivational Interviewing training at peer-to-peer helpline. The study will leverage emerging technologies to surmount the challenges of providing tailored training to a large and diverse mental health workforce at scale. Aim 1: Adapt Motivational Interviewing (MI) strategies for use in a teen peer-delivered text-based digital helpline. Aim 2: Co-design performance feedback (PF) and facilitated practice (FP) processes to support MI adherence among peer helpers. Aim 3: Examine feasibility, acceptability, and initial outcomes in a pilot feasibility trial. Peer helpers (N=50) will be randomized to receive MI training or MI training + PF-FP.
