Social skills acquired during early childhood are often the foundation for success later in life. Using a nationwide survey dataset in Japan, this study aims to explore the multiple growth trajectories of social skills among children in kindergarten by using a latent class growth modeling approach. It also examines whether, and to what extent, the home-rearing environment at early age predict trajectories of social skills development. Children in this study were assessed on social skills at three waves, four home-rearing environment dimensions (human stimulation, social stimulation, avoidance of punishment, and social support for parenting) and demographic background were measured at wave 1. The results indicated that three distinct growth trajectories of social skills existed during kindergarten: high increase levels, moderate increase levels, and decreased levels. The avoidance of punishment and children’s gender significantly predicted the growth trajectories of social skills. Thus, the results suggest that more attention should be paid to the home-rearing environment and boys.

Resilience plays an important role in the relationship between adverse childhood experiences (ACEs) and children’s health. Young children are often neglected in ACEs research and suffer from the negative consequences of ACEs. However, few studies have focused on the relationship between ACEs and emotional problems in young Chinese children and the moderating and mediating effect of resilience on this relationship. This study included young children at the beginning of their kindergarten year (n = 874, 42.80 ± 4.09 months) from Wuhu City, China, to examine the mediation and moderation effects of resilience on early-life ACEs and emotional problems. Our results show a positive direct effect of ACEs on emotional problems. Furthermore, a positive indirect effect of ACEs and emotional problems on resilience was found. A moderating effect of resilience was not observed in this study. Our findings (a) highlight the significance of paying more attention to early ACEs and revealing a better understanding of the effect of resilience on ACEs at an early age and (b) indicate that age-specific interventions should be provided to enhance young children’s resilience when exposed to adversity.

Background: Although intergenerational transmission of ACEs among parents and their offspring have been extensively studied in the West, few studies have been conducted in China on preschool children and their parents, and explore the protective fact for the intergeneration transmission. Objective: Using latent class analysis and moderation model, this study examined the associations between patterns of adverse childhood experiences of Chinese preschool parents and behavioural problems in their children and whether coparenting quality plays a protective role in this relationship. Method: A retrospective study was conducted on 3091 parent–child dyads from 11 kindergartens in the northern, central, and southern Anhui provinces in China. Online questionnaires were used to collect the data. Parents reported adverse childhood experiences (ACEs) and provided information on their children's behavioural problems and perceived coparenting quality. Latent class analysis and a moderating model were used to examine the associations between patterns of adverse childhood experiences of Chinese preschool parents and behavioural problems in their children, and the moderating role of coparenting quality. Results: Four classes were identified: a high ACEs group, a violent victimisation group, a child abuse and physical neglect group, and a low ACEs group. Increasing levels of co-parenting quality were associated with reduced parent-reported child behaviour problems for all classes, and that potentially buffering effect was significantly stronger for the low ACEs class than for children whose parents in high ACEs class. Conclusions: Exposure to high ACEs increases the risk of developing behavioural problems in offspring, and coparenting quality may serve as a protective mechanism for intergenerational transmission. Future research should develop and implement interventions to support disadvantaged, at-risk parents and promote coparenting quality.

Externalizing and internalizing behavioral problems occurs at a high rate among children. However, this has rarely been examined among Japanese children using a person-oriented method. Hence, this study aims to explore its subtypes and clarify their association with family-based group activities. We conducted a cross-sectional survey in a typical community-based suburban area for all families with primary school children in Japan. We investigated children’s internalizing and externalizing behaviors based on the Japanese version of the Strengths and Difficulties Questionnaire (SDQ), and different types of activities that family members frequently engaged in. Data from 206 families were collected and used for the analysis. The subtypes were explored using latent class analysis (LCA). The relationship between family activities and latent class membership was analyzed using a logistic regression model. Moreover, three latent class models and their probabilities were identified, namely, risk group (31.3%), moderate group (44.9%), and normal group (23.8%). Frequent family activities including play sports, traveling or hiking, watching TV and communicating, cooking or making a dessert, and doing housework, which were significantly related to the normal group. These results would add evidence to potential types of children’s behavioral problems and preventive childcare practices needed in the primary gate of families.
