Relationship Between Sleep Irregularity and School Non-Attendance Among Japanese Elementary and Junior High School Students
Background/Objectives : In Japan, the number of elementary and junior high school students who do not attend school is increasing. Sleep problems are considered a contributing factor. Methods : This study utilized self-administered questionnaires about the sleep patterns and backgrounds of 25,257 students from the 3rd-10th grades across 91 elementary schools, 51 junior high schools, and 36 high schools in Japan. Latent class analysis was performe…
Psychometric validation of the WHO-5 and WHO-4 well-being index scales for assessing psychological well-being and detecting depression in Japanese school-aged children
Introduction: The 5-item World Health Organization Well-Being Index (WHO-5) is widely used to assess psychological well-being, but its psychometric properties in younger populations, particularly in non-Western settings, remain underexplored. This study aimed to assess the validity and reliability of the Japanese version of the WHO-5 (WHO-5-J) and a culturally adapted four-item version (WHO-4-J), which excludes a culturally sensitive item ("I hav…
Multifaceted perception of school climate
Introduction This study aimed to investigate whether there is a significant association between teachers’ and students’ perceptions of school climate, and if not, whether teacher factors are associated with the respective perceptions. Methods The participants included 1,831 students and 59 homeroom teachers from 11 public elementary and junior high schools in Japan. Multilevel models were used to examine the association between students’ and teac…
Early detection of students’ mental health issues from a traditional daily health observation scheme in Japanese schools and its digitalization
Objective: The implementation of school-based mental health screening offers promise for early detection of mental health issues in children; however, various barriers hinder its widespread adoption. This study aimed to investigate the predictive value of digital data obtained from an established daily health observation scheme in Japanese schools to identify later mental health issues in children. Methods: Data for the analysis were obtained fro…
Adverse childhood experiences
Background: Adverse childhood experiences (ACEs) have been found to negatively impact adult mental health outcomes. Numerous studies have highlighted on ACEs in family and community settings. However, few have examined the impact of ACEs in school settings, despite the potential influence on social participation. Hikikomori, characterized by severe social withdrawal, was first studied in Japan and has gained recognition in recent years. The prese…
Autism symptoms, functional impairments, and gaze fixation measured using an eye-tracker in 6-year-old children
Introduction Autism spectrum disorder (ASD) is a neurodevelopmental disorder clinically characterized by abnormalities in eye contact during social exchanges. We aimed to clarify whether the amount of gaze fixation, measured at the age of 6 years using Gazefinder, which is an established eye-tracking device, is associated with ASD symptoms and functioning. Methods The current study included 742 participants from the Hamamatsu Birth Cohort Study. …
Longitudinal association between addictive internet use and depression in early adolescents over a 2-year period
Although addictive internet use (AIU) and depression frequently co-occur in early adolescents, the mechanism accounting for their co-occurrence remains unclear. The aim of the present study was to clarify the longitudinal reciprocal relationships between AIU and depression in early adolescents. We employed a random intercept cross-lagged model to examine the longitudinal reciprocal relationships between AIU and depression in a sample of the early…
Associations Among Maternal Metabolic Conditions, Cord Serum Leptin Levels, and Autistic Symptoms in Children
The present study uncovered an association between cord leptin levels and autistic symptoms in children, while maternal metabolic conditions did not have an evident direct influence on the outcome. These results imply that prenatal pro-inflammatory environments affected by maternal metabolic conditions may contribute to the development of autistic symptoms in children. The findings warrant further investigation into the role of leptin in the deve…
The Role of the Maternal and Child Health Handbook in Developmental Surveillance
Despite the pivotal role of developmental surveillance in pediatric practice for the early detection of neurodevelopmental disorders (NDDs), there are several barriers, including scarcity of time and staff availability, to its implementation. Additionally, inadequate parental knowledge on what to expect about their child's development contributes to potential delays in the early identification of NDDs. Home-based records (HBRs) are widely used in…
Trajectories of Adaptive Behaviors During Childhood in Females and Males in the General Population
Little is known about the trajectory patterns and sex differences in adaptive behaviors in the general population. We examined the trajectory classes of adaptive behaviors using a representative sample and examined whether the class structure and trajectory patterns differed between females and males. We further explored sex differences in neurodevelopmental traits in each latent class. Participants ( n = 994) were children in the Hamamatsu Birth…
Measuring School Climate among Japanese Students—Development of the Japan School Climate Inventory (JaSC)
School climate is a significant determinant of students' behavioral problems and academic achievement. In this study, we developed the Japan School Climate Inventory (JaSC) to see whether it measures school climate properly. To do so, we investigated whether or not the measurement with JaSC varies across sub-groups of varying grade and of gender and examined the relationship between the perception of school climate and the psychological and behav…
Impaired executive function in junior high school students with excess sleep time
We examined the relationship between sleep habits and executive function (EF) in Japanese junior high school students.This study was conducted using an online survey involving 1,919 boys and girls (aged 12–15 years) and their caregivers.Sleep habits were measured with the Japanese Sleep Questionnaire for junior high school students (JSQ-JH). EF was measured with the parental form of the Japanese version of Behavior Rating Inventory of Executive F…
