Abstract

Aim: Establishing a coparenting relationship that shares child-rearing responsibilities is crucial for couples. This study used paired data to identify parenting and psychosocial characteristics based on couple coparenting relationships with their first child at one year of age.

Methods: Eighty-six couples were analyzed in three clusters using the Coparenting Relationship Scale (CRS-J). Each cluster was then assessed for the Quality Marital Index (QMI), Parenting Self-efficacy Scale (PSE), Parenting Stress Index (PSI), depression scale, childcare enjoyment and difficulty; housework and childcare sharing ratios and satisfaction; and childcare time and frequency.

Results: The wives’ and husbands’ average ages were 32.7 and 34.3, respectively, with 80.2% of the wives unemployed. Cluster 1 wives had higher CRS-J scores than their husbands; husbands performed a higher share of housework and childcare, and had longer childcare time, higher bathing frequency, greater childcare difficulty, and higher depression risk (p = .031 to <.001). Cluster 2 featured higher CRS-J scores for both partners; both had higher childcare enjoyment and lower depression risk, and husbands scored higher QMI and PSE, and lower PSI (p = .040 to <.001). Cluster 3 husbands scored higher on CRS-J compared to their wives; wives scored lower on QMI and sharing satisfaction, and higher on childcare difficulty, PSI, and depression risk (p = .012 to <.001).

Conclusion: The coparenting relationships were characterized by three. These findings highlight the importance of providing tailored support that addresses specific coparenting relationships.
