Overparenting is an emergent parenting style where parents are highly involved in their children's routines and they remove the perceived obstacles that may happen in their children's lives. However, validated measures that objectively assess overparenting are severely lacking in the Chinese communities. Based on a sample of 642 undergraduate students from Hong Kong, psychometric properties of the perceived Chinese Paternal Overparenting Scale (CPOS) and Chinese Maternal Overparenting Scale (CMOS) were examined in terms of internal consistency, test-retest reliability, convergent validity and factorial validity. Results indicated that both CPOS and CMOS showed good internal consistency and test-retest reliability. As predicted, the findings gave support for the convergent validity of the scales: CPOS and CMOS were significantly related to measures of paternal and maternal behavioral control, psychological control, and support; they were also negatively associated with self-efficacy but positively related to narcissistic behavior of emerging adults. Moreover, factor analyses showed that eight factors corresponding to the proposed conceptual model were abstracted from the CPOS and CMOS, respectively. The present study suggests that both CPOS and CMOS are reliable and valid assessment tools that can be used to measure parental overparenting in the Chinese context.
