By Janowski R, Shenderovich Y, Wamoyi J and 4 others.
Abstract
Background
Digital health interventions are rapidly expanding in low- and middle-income countries (LMICs), yet little is known about how design and delivery components can be tailored to support engagement across diverse populations. Addressing this gap is critical for effective and equitable implementation.
Purpose
This study used a factorial experiment, embedded within the Optimization Phase of the Multiphase Optimization Strategy (MOST), to examine whether caregiver characteristics moderated the effects of design and delivery components on engagement with an app-based parenting intervention in Tanzania.
