Organizational trust, usability, and inclusivity are key implementation facilitators for a proposed assets-based mobile health intervention.

Assets-based interventions can address child health disparities by connecting families to existing community resources. Community collaboration when designing interventions may identify barriers and facilitators to implementation. The objective of this study was to identify crucial implementation considerations during the design phase of an asset-based intervention to address disparities in childhood obesity, Assets for Health. We conducted focus groups and semi-structured interviews with caregivers of children (<18 years) (N = 17) and representatives of community-based organizations (CBOs) which serve children and families (N = 20). Focus group and interview guides were developed based on constructs from the Consolidated Framework for Implementation Research. Data were analyzed using rapid qualitative analysis and matrices were used to identify common themes within and across groups of community members. Desired intervention characteristics included an easy-to-use list of community programs that could be filtered based on caregiver preferences and local community health workers to promote trust and engagement among Black and Hispanic/Latino families. Most community members felt an intervention with these characteristics could be advantageous versus existing alternatives. Key outer setting characteristics which were barriers to family engagement included families' financial insecurity and lack of access to transportation. The CBO implementation climate was supportive but there was concern that the intervention could increase staff workload beyond current capacity. Assessment of implementation determinants during the intervention design phase revealed important considerations for intervention development. Effective implementation of Assets for Health may depend on app design and usability, fostering organizational trust and minimizing the costs and staff workload of caregivers and CBOs, respectively.
