Results from a Remote, Caregiver-Mediated Language Intervention
Duet 2.0 is a remote, caregiver-mediated, early language intervention serving English- and Spanish-speaking families experiencing economic adversity in the Philadelphia area evaluated via randomized controlled trial. We hypothesized that (1) child language outcomes, (2) social contingency, (3) caregiver developmental knowledge, and (4) caregiver feelings of self-efficacy at three-month follow-up and six-month follow-up would benefit from Duet 2.0. Participants were caregivers and their children who entered the study at 12-30 months of age. The analytic sample included baseline data from 39 dyads; a total of 26 dyads completed at least one follow-up data collection. Duet 2.0 was positively associated with only the transcribed child expressive vocabulary measure (medium effect at 3mo), but not the standardized expressive vocabulary inventory. Social contingency (large effect at 3mo), caregiver developmental knowledge (large effect at 3mo, small at 6mo), and caregiver self-efficacy (in play contexts: small effect at 6mo; in teaching contexts: medium effect at 3mo, large at 6mo) were positively associated with the intervention. This exploratory sample with low-resourced families demonstrates the potential of this intervention to impact families’ lives and may suggest the value of lighter touch interventions, which can be scaled more easily to improve access for more families.
