", "\nAbstract\n\nObjective\nThis study evaluated the psychometric properties of a Chinese version of the Socialization of Coping scale and examined its longitudinal associations with child outcomes.\n\n\nBackground\nSocialization of coping (SOC) influences children's coping and adjustment, yet its cultural variability remains underexplored.\n\n\nMethod\nIn Study 1, 1,135 parents of primary‐school children completed the SOC alongside measures of coping with children's negative emotions, parent–child relationships, and parenting practices. In Study 2, 400 mother–child dyads provided longitudinal data on SOC and children's coping and adjustment over 6 months.\n\n\nResults\nFactor analyses supported a robust two‐factor structure and demonstrated scalar invariance across parent gender, child gender, and age. The scale demonstrated good reliability and validity. Longitudinal modeling showed that maternal SOC predicted children's coping and adjustment over time. Notably, disengagement SOC emerged as culturally distinctive. It was associated with both supportive and unsupportive parenting practices, and with both adaptive and maladaptive child outcomes.\n\n\nConclusions\nThese findings highlight the dual nature of disengagement SOC in China, reflecting culturally sanctioned socialization practices that may confer either benefits or risks depending on context. The study expands SOC theory and highlights the need for culturally sensitive research and intervention.\n\n"]
