Literacy Instruction Through Media for Everyone

The proposed study draws upon an implementation science framework (Nilsen, 2015) to determine the extent to which a media-based caregiver-led intervention improves caregiver adherence and in turn children's early literacy development relative to a shared reading intervention. Caregiver-implemented shared reading interventions represent the 'current standard practice' for addressing early literacy needs, yet many caregivers cannot implement this practice with adequate adherence. This is particularly true for low-socioeconomic status families, in which shared reading may not be a conventional activity and barriers inhibit its use. The investigators propose-and test-that a media-based intervention reduces barriers to intervention implementation and increases social validity, leading to higher levels of adherence and, via mediation, enhanced child literacy outcomes. To establish this causal chain, the investigators mplement a media-based early literacy intervention, compare it to a highly aligned shared reading intervention, and measure (1) social validity of the intervention to test whether use of media circumvents barriers, (2) caregiver adherence (i.e., frequency and dosage), and (3) child early literacy skills gains immediately and over time. As the first causally interpretable study to compare media and shared reading as caregiver-led interventions, the proposed project will identify strategies to improve adherence in home-based interventions and inform development of interventions to improve school readiness among low-SES children.
