Abstract

Background Excessive digital screen exposure (≥1 hour per day) is associated with limited growth and development in children. Objective This study aims to develop and assess a multicomponent intervention program s effectiveness in reducing excessive screen time among children aged 2-5 years. Methods A theory-based multicomponent intervention known as Program to Lower Unwanted Media Screens (PLUMS) at the household level has been developed. It is based on the social cognitive theory for children and self-determination theory for caregivers. After pretesting, a randomized control trial will be conducted to assess this intervention s effectiveness among healthy children aged 2-5 (±3 months) years and their primary caregivers who have at least one digital media gadget at home in zone three of Chandigarh (population of 2,730,035). A sample size of 428 children is estimated per arm. PLUMS includes disseminating specific information, education, communication in the form of videos and posters to the primary caregivers, and conducting motivational interviewing as and when needed. Children will be provided suggestions for playful activities as alternatives to digital media gadgets. The primary outcome is the mean change in the duration of screen time, and secondary outcomes are sleep duration and patterns, emotional-behavioral problems, and level of physical activity of the children. Per-protocol and intention-to-treat analyses will be conducted using SPSS for Macintosh, Version 25.0. Results The intervention package will be disseminated once a week for 8 weeks to the participants via the caregivers preferred means of communication. The endline assessment will be done immediately postintervention and after the 6 months of follow-up.
