Patterns of Movement Performance Among Japanese Children and Effects of Parenting Practices: Latent class analysis

Objectives: The study aimed to examine the long-term effects of parenting practice during preschool years on children’s movement performance in primary school. Methods: This study involved a three-year longitudinal study including 225 children aged 3–6 years old. Parents reported baseline parenting practice and evaluated children’s movement performance three years later. Latent class analysis was used to explore latent classes of movement performance. A post hoc test was used to identify the characteristics of different patterns. Finally, adjusted multinomial logistic regression models were used to test the influence of parenting practice on identified patterns of movement performance. Results: Children in this study were grouped into three movement performance pattens, labelled as ‘least difficulties’ (58.2%, n = 131), ‘low back pain’ (30.2%, n = 68), and ‘most difficulties’ (11.6%, n = 26). After controlling for age, gender, having siblings or not, family structure, BMI SDS, sleep condition and dietary habits, we found that if parents played games with children frequently, the children would have a 0.287 times lower probability of being in the ‘low back pain’ class, 95%CI [0.105, 0.783], and if parents take children to meet peers of a similar age frequently, the children would have a 0.339 times lower probability of being in ‘most difficulties’ class, 95%CI [0.139, 0.825]. Conclusions: Primary healthcare providers should pay careful attention to children with movement difficulties. The study provides longitudinal evidence to support the applicability of positive parenting practice in early childhood to prevent children’s movement difficulties.

The relationship between the development of social competence and sleep in infants: a longitudinal study

BackgroundMany reports argue that sleep is important for children’s health, learning, and academic performance. The purpose of this longitudinal study was to examine the association between sleep and the development of social competence in infants.MethodsThis study was conducted as part of a Japan Science and Technology Agency (JST) project. Caregivers responded to the Japan Children’s Study Sleep Questionnaire when children were 18 months old. The interactions of caregivers and children were observed when children were 18, 30, and 42 months old, and rated with the Interaction Rating Scale, which is a measure of social competence.ResultsNocturnal sleep duration of more than 10 h and an earlier bed time than 22:00 were significantly correlated with two trajectory groups (low point and high point transition groups) of children’s social competence at 18, 30, and 42 months. Further, total sleep duration of more than 12.25 h and an earlier bed time than 22:00 were significantly correlated with the trajectory of children’s social competence at 18, 30, and 42 months.ConclusionsSleep duration and sleep onset time are important factors in children’s development of social competence

Interaction Rating Scale (IRS) as an Evidence-Based Practical Index of Children’s Social Skills and Parenting

Background: The purpose of this paper is to describe the features of the Interaction Rating Scale (IRS) as an evidence-based practical index of children’s social skills and parenting.Methods: The participants in our study, which was conducted as part of a Japan Science and Technology Agency (JST) project, were 370 dyads of children (aged 18, 30, and 42 month) and 81 dyads of 7-year-old children with their caregivers. The participants completed the five minute interaction session and were observed using the IRS.Results: The results indicated that the IRS can measure children’s social skill development and parenting with high validity. Along with the discriminate validity for pervasive development disorder (PDD), attention-deficit/hyperactivity disorder (ADHD), abuse and maltreatment, a high correlation with the SDQ (Strength and Difficulties Questionnaire), and high reliability, the IRS is effective in describing features of social skill development.Conclusions: The IRS provides further evidence of the fact that in order to study children’s social skill development, it is important to evaluate various features of the caregiver-child interaction as a predictor of social skills

Does Night Care Affect Development? A Five-year Follow-up

Japanese regulations have aimed to monitor night care for children since 1981, when a tragic accident took the life of a child in an unauthorized child care center. Nevertheless, concerns persist about the efficacy of the care of children outside the home during the nighttime hours. This longitudinal project assessed the development and adaptation of children who had been in night care for a period of five years. Parents and child care professionals completed surveys: The former about the home environment and their own perceptions of their experience of childrearing, and the latter about the children’s development. The results suggest that factors in the home environment, rather than center-based care, explain developmental risks

Development of Social Skills in Kindergarten: A Latent Class Growth Modeling Approach

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

Influence of Maternal Praise on Developmental Trajectories of Early Childhood Social Competence

We aimed to clarify the effects of the praise of mothers on their 18-month-old offspring by tracing the trajectory of the latters ’ social competence from this time to 30 and 42 months. The participants were 226 mother-child dyads whose interaction was observed when the children were 18, 30, and 42 months old. The features of mother-child interaction, and specifically the social proficiency of the children, were examined using the Interaction Rating Scale (IRS) as an aspect of social competence. Our findings indicate that caregivers ’ praise of 18-month-old children is very important in promoting a high-level trajectory of child social competence from that time to 30 and 42 months. It is hoped that caregivers and health care professionals will use these findings appropriately when providing care giving support to parents

Subtyping of Internalizing and Externalizing Behaviors in Japanese Community-Based Children: A Latent Class Analysis and Association with Family Activities

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
