Measurement, Process, and Cultural Validity in Mindful Parenting and Preschool Peer Social Competence: Implications for Early Childhood Education [Letter]

Abstract

Li et al 1 examined the associations among mindful parenting, children’s emotion regulation, parent–child relationship quality, and peer social competence in a sample of 531 Chinese families with kindergarten children. The multi-regional sample and the focus on preschool peer competence represent meaningful contributions. The reported positive association between mindful parenting and peer social competence, together with the partial mediating role of emotion regulation, aligns with emotion socialization perspectives. Nonetheless, several interconnected scientific issues constrain the strength of the inferences and point toward more rigorous avenues for future work. Because peer social competence is a central developmental task in early childhood education settings, the measurement and process limitations identified here have direct implications for kindergarten practice, family-school collaboration, and early intervention. The most fundamental limitation is the exclusive reliance on parent report for all focal constructs. Mindful parenting, parent–child relationship quality, children’s emotion regulation, and children’s peer social competence were assessed solely by the same parent. Although Harman’s single-factor test indicated that the first factor explained 34.25% of the variance, this diagnostic is known to be insensitive. More importantly, the design confounds informant and construct. Parents have limited opportunity to observe children’s peer interactions in kindergarten settings. Peer social competence is most validly assessed within the peer ecology itself through teacher ratings, peer nominations, or structured observation. Recent multi-informant research 2 on emotion regulation demonstrates only modest correspondence between parent and child reports and shows that each perspective contributes complementary predictive information about emotional functioning. Parallel concerns apply to the measurement of mindful parenting. Scale-development work has explicitly recognized that parent-report inventories are vulnerable to shared-reporter bias and has therefore introduced parallel child-report measures. 3 When predictor, mediator, and outcome share the same informant, observed associations risk reflecting common method variance and evaluative consistency rather than distinct developmental processes. A closely related issue is conceptual and item-level
