The goal of this project is to develop, refine, implement, and evaluate an intervention that addresses the well-being of the Head Start workforce at the individual and organizational levels. The intervention, “Well-Being First”, will be adapted from a variety of evidence-based strategies in education and human services and will include a series of trainings, collaborative group processing, leadership support, monthly consultation, and a well-being toolkit. The intervention will seek to strengthen resilience, improve the psychosocial work environment, and provide leadership support. The project will begin with a two-year period of development and refinement of the intervention that will include two pilot testing phases. The intervention will then be evaluated through a cluster randomized controlled trial (RCT) across 30 programs.
