RESUMEN
Many parents attempt to limit adolescents' screen time without changing their own habits. We examined whether "whole-family" versus "youth-focused" restrictions differentially predict social media-related difficulties (procrastination and problematic use), and whether adolescents' impulsive social media behaviors moderated these relationships. Among 183 Chinese early adolescents (58.5% female), whole-family rules negatively predicted procrastination. Impulsivity moderated associations between rulemaking approaches and social media difficulties; youth-focused rules negatively predicted procrastination and problematic use for highly impulsive adolescents, while whole-family rules held no associations or predicted increased difficulties. For less impulsive adolescents, however, whole-family rules negatively predicted social media difficulties and youth-focused rules positively predicted problematic use. Results suggest that setting the implementation of screen rules should involve parental participation and consideration of individual differences.
