Engagement in a Preventive Intervention for Preadolescent Children in Foster Care: Considerations for Intervention Design.

Engagement in mental health-focused preventive interventions is understudied. Demographic, child, and system-level predictors of engagement were explored in a study with children in foster care (N = 222, Mage = 10.3) who participated in a 30-week intervention. Attendance and engagement in mentor visits and skills groups were rated weekly. Only 4 of 21 predictors showed bivariate associations with attendance/engagement: child sex, IQ, behavior problems, and trauma symptoms. SEM models with these three variables and a measure of adverse childhood experience (ACEs), were used to develop a model of engagement. Males had poorer mentor visit and group engagement. Group attendance was positively associated with trauma symptoms and negatively associated with ACEs. Group engagement was associated with higher IQ and fewer behavior problems. A contextually-sensitive intervention can result in high engagement for a vulnerable and diverse population, yet a few child factors still impacted engagement, and when identified could be ameliorated.
