Identifying age 26 as a threshold in psychosocial risks associated with child maltreatment among first-time mothers
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
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 …
Longitudinal associations between informal caring, social network, and psychological distress among adolescents and young adults
Increased psychological distress and social network preceded the onset of informal caring among young persons. Incorporating psychological distress assessment may benefit the early identification of and support for young carers. The long-term interplay between social networking and informal caring needs further clarification
The silent crisis in girls' mental health
Adolescent psychotic experiences before and during the Covid ‐19 pandemic
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 …
Association between advance care planning and depressive symptoms among community-dwelling people with dementia
Objectives: Advance care planning (ACP) is an increasing priority for people with dementia during the COVID-19 pandemic. This study evaluated the association between ACP initiation and depressive symptoms among home-dwelling people living with dementia. Methods: An internet-based questionnaire survey was conducted with Japanese family caregivers of home-dwelling persons with dementia in June 2021. Family caregivers evaluated the level of depressi…
Night-time population consistently explains the transmission dynamics of coronavirus disease 2019 in three megacities in Japan
Background: Mobility data are crucial for understanding the dynamics of coronavirus disease 2019 (COVID-19), but the consistency of the usefulness of these data over time has been questioned. The present study aimed to reveal the relationship between the transmissibility of COVID-19 in Tokyo, Osaka, and Aichi prefectures and the daily night-time population in metropolitan areas belonging to each prefecture. Methods: population in downtown areas e…
Informal Caregiving in Adolescents from 10 to 16 Years Old
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
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
Being Praised for Prosocial Behaviors Longitudinally Reduces Depressive Symptoms in Early Adolescents
Being praised for prosocial behavior rather than objective prosocial behavior at 10 years of age predicted lower depressive symptoms 2 years later. Praise for adolescents' prosocial behavior can be encouraged to prevent depression
Migration and psychotic experiences in the Tokyo Teen Cohort
The findings suggest that migrant status is associated with increased likelihood of psychotic experiences at age 10 in Tokyo, Japan. Future prospective research should explore social exclusion as a potential underlying mechanism and can further clarify the protective role of IQ and related factors
Longitudinal Bidirectional Relationships Between Maternal Depressive/Anxious Symptoms and Children's Tic Frequency in Early Adolescence
Background: Previous studies have revealed an association between maternal depressive/anxious symptoms and children's tics. However, the longitudinal relationships between these symptoms remain unclear. We examined the longitudinal relationships between maternal depressive/anxious symptoms and children's tic frequency in early adolescence with a population-based sample. Methods: The participants consisted of 3,171 children and their mothers from …
Assessing the hierarchy of personal values among adolescents
INTRODUCTION: For assessing personal values, the rating scale method may not adequately reflect the hierarchical structure of personal values and tends to be influenced by response style bias. The paired comparison method is considered a promising alternative approach, because it engages comparative judgment and may reduce response style biases. The present study aimed to compare these two methods for assessing the hierarchy of personal values am…
Development of the Brief Personal Values Inventory for Sense of Values
The Portrait Values Questionnaire (PVQ) is a widely used questionnaire for assessing sense of values; however, it is difficult to apply for children and adolescents. Therefore, the present study aimed to develop a questionnaire for sense of values, called the Brief Personal Values Inventory (BPVI), consisting of simple questions and fewer items compared to the PVQ. We first created 12 items for the BPVI and then tested criterion‐related validity …
Bi-Directional Relationships Between Psychological Symptoms and Environmental Factors in Early Adolescence
By using the newly introduced methodology, our results were partly consistent with previous literature. Further studies are needed to validate this methodology and accelerate the findings regarding the emergence of psychological symptoms and the impact of environmental factors from childhood to early adolescence
Dog and Cat Ownership Predicts Adolescents’ Mental Well-Being
A potential association between pet ownership and mental well-being is suggested, but there is a shortage of high-quality longitudinal studies that consider probable differences among different species. We aimed to examine whether ownership of the most popular pets (dogs and cats) would predict mental well-being. The Tokyo Teen Cohort (TTC), a prospective population-based birth cohort study, had dog and cat ownership data at age 10 and mental wel…
