Purpose: This study examined the attributes contributing to the use of technology among school staff to facilitate and promote physical activity. Method: A mixed-methods sequential explanatory research design was employed with the diffusion of innovations theory as a guide. The Comprehensive School Physical Activity Program Technology Practice Questionnaire, a diffusion of innovations questionnaire, and semistructured interviews were used to collect data. Multiple regression analysis and open and axial coding techniques were conducted to analyze quantitative and qualitative data, respectively. Results: Complexity and trialability attributes contributed to the use of technology in schools. Despite acknowledging the benefits of technology use in promoting physical activity, school staff also expressed concerns about barriers and risks related to its use. Discussion/Conclusion: The study provides insights into factors affecting the use of technology among school staff and recommends that schools, districts, and professional organizations offer more opportunities for staff to explore and learn about various technologies.
