However, young children may exhibit behavioral challenges in these settings, negatively impacting their social-emotional development. It is critical that the early childhood workforce is prepared to support young children's burgeoning social-emotional skills to address challenging behaviors in early care and education classrooms. Infant and early childhood mental health consultation is an evidence-informed approach for increasing teachers' skills for managing young children's emotions and behaviors. One mechanism to increase teachers' access and use of the infant and early childhood mental health consultation programs is through on-demand mobile apps. Objective: This study aims to investigate 2 primary objectives: to document the development of the Jump Start on the Go (JS Go) app through community-based participatory research (CBPR) methodologies, and to evaluate and refine the app based on early childhood education (ECE) teacher feedback using a mixed methods assessment approach. Methods: This study used a community-based participatory research approach to design and evaluate the effectiveness of the JS Go app across 3 phases. In phase 1, a description of how the JS Go app was developed using CBPR principles is provided. In phase 2, teachers (n=12) were interviewed after reviewing mockups of the JS Go app to gather feedback about the interface and usefulness of the app to current and new teachers. Rapid qualitative analysis generated themes to inform phase 3 (n=31) of the study. Results: Phase 2 findings suggested that teachers viewed the app as aesthetically pleasing with concise information, but there were design and content features that needed to be refined to improve ease of use for accessing content. Teachers also described the app as beneficial and useful to both current and new ECE teachers and identified it as a tool to support sustainability for the use of JS practices. In phase 3, teachers rated the JS Go app favorably across all mHealth (mobile health) App Usability Questionnaire dimensions, including interface satisfaction (mean 6.12 on a 7-point scale), ease of use (mean 5.56), and usefulness (mean 5.37). Despite positive usability ratings, teachers expressed less certain intentions to adopt the app, scoring near the midpoint on the Technology Acceptance Model Instrument-Fast Form's predicted future use scale (mean 1.60, --4 to +4-point scale). Implications for how the findings were used to make adaptions to the app are discussed. The next steps for testing the efficacy of the app in a randomized control trial are described. Conclusions: ECE teachers have overall positive perceptions about the value of the JS Go app. Future research will need to test the efficacy of the app for increasing and sustaining teacher's use of JS practices.
