This study examined the associations of age at dialogic parent – child SR initiation with psychosocial problems among preschoolers, explored the potential moderating role of marital conflicts in this association, and determined the distinct contributions of mother- and father-led SR to psychosocial development. In total, 1,038 parents of 3–5-year-old preschoolers were included. Research Findings: The results showed that children initiating SR after 3 years of age had higher risks of psychosocial problems; dialogic SR was negatively associated with psychosocial problems. The risk of psychosocial problems among children initiating SR at 2–3 years increased with the frequency of marital conflicts. A later initiation of mother – child SR was associated with increased risks of psychosocial problems in a subsample of mother – father pairs; a higher father – child SR frequency was associated with reduced risks of psychosocial problems. Practice or Policy: Our findings suggest that parents should initiate SR as early as possible – particularly in families with frequent marital conflicts – and employ dialogic SR strategies to enhance children’s psychosocial development.enjournal article10.1080/10409289.2025.2568851
