Childhood trauma impacts most children in the United States, with exposure to adverse childhood experiences (ACEs) like abuse, neglect, or witnessing violence linked to negative outcomes across the lifespan. Early childhood education (ECE) programs, such as therapeutic preschools, that utilize two-generation approaches to services have demonstrated proven benefits for children with trauma exposure; however, less is known about the impact of ACEs on early childhood program engagement and retention. The current study, set in a two-generation therapeutic preschool program, examined 173 pairs of primarily Latinx parents and children to understand in what ways parent and child ACEs, coupled with family contextual risks like homelessness and child welfare involvement, impact program engagement for children with trauma histories. Results indicate that children whose parents had an elevated ACE score (four or more trauma experiences) were more likely to terminate ECE participation early compared to children whose parents had less cumulative trauma. Families with parents and children who both had high ACEs were over six times more likely to terminate program participation early. However, once accounting for early termination, ACEs had minimal impact on ECE engagement. These findings highlight the need for ECE programs to consider the whole family at entry and target early retention efforts towards families with greater cumulative trauma histories. (author abstract)
