  • Identifying age 26 as a threshold in psychosocial risks associated with child maltreatment among first-time mothers

    Open Access•Kaori Baba, Syudo Yamasaki et al.•ARTICLE•Frontiers in Public Health•2026

    Background Early pregnancy is associated with increased psychosocial vulnerability, which has been linked to factors associated with child maltreatment. However, previous research has predominantly focused on teenagers, and little is known about whether first-time mothers in their early-to-mid twenties also exhibit elevated psychosocial risks. This observational cross-sectional study aimed to determine whether psychosocial risk factors associated…

  • Loneliness patterns across time and subsequent risk of psychotic experiences, depression, anxiety, and diminished well‐being in adolescents

    Open Access•Zui C Narita, Jordan Devylder et al.•ARTICLE•Journal of Child Psychology and…•2026

    BACKGROUND: Evidence on the association between loneliness and psychotic experiences in adolescents remains limited. Moreover, loneliness has typically been assessed at a single time point, which fails to capture its dynamic nature. We hypothesized that persistent loneliness, assessed across repeated measures, would be associated with psychotic experiences and other mental health problems. METHODS: Using longitudinal data from 3,171 participants …

  • Adolescent psychotic experiences before and during the Covid ‐19 pandemic

    Open Access•Jordan Devylder, Satoshi Yamaguchi et al.•ARTICLE•Journal of Child Psychology and…•2024

    BACKGROUND: Understanding the etiology of psychosis is essential to the development of preventive interventions. The COVID-19 pandemic provides a rare natural experiment that can expand our understanding of the role of social factors in the trajectories and etiology of psychosis across adolescence, particularly in Tokyo where the prevalence of actual COVID-19 infection remained low. We hypothesized that the likelihood of self-reporting psychotic …

  • Informal Caregiving in Adolescents from 10 to 16 Years Old

    Open Access•Masao Nakanishi, Daniel Stanyon et al.•ARTICLE•International Journal of…•2023

    There is growing evidence of the impact of informal caregiving on adolescent mental health, and its role is often hidden unintentionally or intentionally, which may hamper early identification and support for young informal caregivers. However, the quantitative evidence regarding household factors relating to informal caregiving has mostly been based on cross-sectional findings. This study examines the longitudinal associations between household …

  • Self-Reported Maternal Parenting Stress From 9 m Is Longitudinally Associated With Child ADHD Symptoms at Age 12

    Open Access•Kaori Endo, Daniel Stanyon et al.•ARTICLE•Frontiers in Psychiatry•2022

    We identified associations between parenting stress at 9-10, 18 and 36 m after childbirth and child ADHD symptoms at 12 years old. Self-reported parenting stress data may have utility as an early indicator for ADHD risk. Participation in early-life health checks, assessment of parenting stress, and tailoring support to family needs should be promoted for early identification and intervention for ADHD
