Research suggests gender inequalities in adolescent mental health are context dependent and might be preventable through social structural change. However, variations the size of across diverse cultural contexts could due to incomparable measurement. We aimed compare a measurement among young people Tokyo, Japan, London, UK, test hypothesis that depressive symptom trajectories larger London than Tokyo.

However, no longitudinal study has examined the direction of this association. The current investigated whether are reciprocally associated at within-person (individual) level during early to mid-adolescence.Longitudinal data on in adolescents were obtained from a population-based birth cohort (Tokyo Teen Cohort; N = 3,171) four time points (10y, 12y,...

Adolescent loneliness is a growing public health issue owing to its adverse impact. Although adolescent common, trajectories can show distinct patterns over time. However, there limited knowledge regarding their determinants, particularly for chronic loneliness.

Abstract Background and Hypotheses A wealth of evidence suggests that adolescent psychotic experiences (PEs), especially auditory hallucinations (AHs), are associated with an increased risk for self-injurious behavior (SIB). However, the directionality specificity this association not well understood, there no published studies investigating within-person effects over time. The present study aimed to test whether AHs SIB prospectively increase reciprocal at individual level during...

However, there has been a scarcity prospective longitudinal on this topic.We investigated association between presence and among adolescents using data from population-based birth cohort study (Tokyo Teen Cohort; N = 3171). Psychotic were assessed at three timepoints two-year intervals through early adolescence (age 10, 12, 14).After adjusting...
