This document summarizes research presented at the Johns Hopkins University Department of Psychiatry Research Conference on using technology to promote mental health. It describes several text messaging-based programs for smoking cessation, sexual health promotion, and bullying prevention that were developed using multi-step processes including formative research, content development and testing, and pilot randomized controlled trials. Key lessons learned included the importance of usability testing, addressing barriers to program engagement, and ensuring safety in interactive programs. Preliminary results found these types of programs showed promise in improving health outcomes.
