About the study

The goal of this clinical trial is to test ways to improve early language development among young children of parents with substance use disorder (SUD). Children of parents with SUD are at increased risk for language delays, and early supports may help prevent long-term learning challenges. This study will examine whether adding additional supports to group-based parenting intervention improves child language outcomes compared to the group intervention alone.
