Parental marriage and the non-cognitive abilities of infants and toddlers: Survey findings from China Family Panel Studies

Early childhood is a critical period for developing children's abilities. Non-cognitive abilities are comparable to or even stronger than cognitive abilities in predicting many socioeconomic outcomes. Usually, most scholars take personality as the core indicator of non-cognitive abilities. While temperament is also an important component of children's non-cognitive abilities, it was often ignored in previous studies. Based on the panel data from the 2018 and 2020 China Family Panel Studies (CFPS), this study investigates the effects of parental marital satisfaction on the non-cognitive development of children aged one to three; meanwhile, the heterogeneous effects and mechanisms were also examined. The results show that young children exhibit more negative emotions when their parents reported dissatisfaction with their marriages. Parental depression was an important mechanism of parental marital satisfaction affecting children's non-cognitive development, while the frequency of parent-child interaction was not. The effects of marital dissatisfaction on non-cognitive abilities were heterogeneous across child age and gender, as well as parental genders and education levels. The findings shed some light on the early interventions and offer important reference values for public policies aimed at improving family welfare and children's non-cognitive development.
