Optimizing Research With Diverse Families - Feasibility and Acceptability Study (FAST)

This study will test the feasibility of recruiting and completing a multinutrient trial with racially and ethnically diverse participants (N=30), focused on Black and Hispanic families, and the acceptability of the intervention, and refined collection methods. The 8-week, open-label, study will evaluate the feasibility and acceptability of collecting (a) real-time ecological momentary assessment (EMA) data on child's target behavior problem, as identified by parent and (b) two types of bio-specimens (blood and urine) collected at home while taking the multinutrients daily.
