Sustainability of evidence-based practices is a known barrier in implementation science, including evidence-based mental health practices in early care and education (ECE) centers. Evidence-based infant/early childhood mental health consultation (IECMHC) support young children's social and emotional development and prevent expulsion and suspension from ECE programs. Young children are ten times more likely to be expelled from early care and education programs compared to school-age children, with black, Hispanic, and children with disabilities at an even higher risk. The Jump Start program provides mental health consultation to childcare centers to improve their capacity to work with children with challenging behaviors and reduce rates of expulsion from preschool. We developed a mobile application that provides mental health resources to childcare center teachers as a strategy that can lead to sustained use of evidence-based IECMHC practices by maintaining access to mental health strategies even after completion of the intervention. The Jump Start mobile application is a free downloadable app that ECE teachers can use to access resources related to improving 4 areas: 1) Self-Care strategies to improve resiliency, 2) Communication strategies to improve parent and teacher exchange of information, 3) Behavior Support strategies to reduce challenging behaviors, and 4) Safety strategies to reduce the risk of infectious disease. The purpose of this study is to understand the effectiveness of the mobile app in improving teacher and child outcomes. Our sample included 82 early childhood teachers and children ages 2-5. Results from our study showed improvements in classroom practices that promote nurturing quality care as seen on the Health Environment Rating Scale. In addition, we saw improvements in child resiliency as measured by the Deveraux Early Childhood Assessment (DECA). The results can be used to inform other IECMHC consultations on ways to enhance program sustainability and improve access to mental health services.
