Specialized and versatile antisocial behavioral profiles in preschoolers: Associations with persistent behavioral problems.

This study investigated specialized and versatile antisocial patterns in preschoolers and examined the link between these patterns and the risk of developing chronic antisocial behaviors throughout childhood. A total of 556 children (50.6% boys, 88% White) participated in this three-wave longitudinal study at 3-5, 6-8, and 10-12 years old.

Do you see what I see? Exploring maternal and child perceptions of children's anxiety longitudinally.

The goals of this study were to investigate (a) the dyadic relations of mothers' and children's perceptions of children's anxiety symptoms across development, (b) whether maternal perceptions of children's anxiety serve as a mediator of the association between maternal anxiety and child anxiety, and (c) whether sensitive/structured parenting moderates these processes. Participants were 180 mother-child dyads (96 female) recruited from Quebec, Canada, and assessed in preschool, middle childhood, and early adolescence. Mothers and children completed questionnaires on children's anxiety, and mothers additionally completed a questionnaire on their own anxiety.

The longitudinal effects of maternal parenting practices on children's body mass index z-scores are lagged and differential.

Background: The longitudinal relation between parenting practices and styles with children's body mass index z-scores (zBMI) is poorly understood. Previous studies suggest the relationship may be complex, but small samples and short follow-ups diminish the strength of the evidence. The objectives of this study were to investigate whether the relationship is bidirectional, time-varying, and lagged using data from a large, representative birth cohort of Quebec children.

Relationship Quality and Mental Health Implications for Adolescents during the COVID-19 Pandemic: a Longitudinal Study.

Although parent-adolescent and peer-adolescent relationship quality are critical for adolescent wellbeing during typical stressful life events, the unique features of the COVID-19 pandemic put into question whether strong parent-adolescent and peer-adolescent relationship quality functioned as protective factors of adolescent mental health in this context. The current longitudinal study examined a community sample of adolescents across 3 time points, each 6 months apart (Time 1: Fall, 2019;  = 163, 50.9% male; mean age = 15.

Associations between early poverty exposure and adolescent well-being: The role of childhood negative emotionality.

Using a longitudinal design (Wave 1 = 164, = 3.57 years, 54% female, predominantly White and French-speaking), the current study sought to answer two questions: 1) does poverty influence children's negative emotionality through heightened family-level, poverty-related stress? and 2) is negative emotionality, in turn, predictive of adolescent internalizing symptoms, externalizing behaviors, cognitive abilities, and physical health? Results confirmed an indirect pathway from family poverty to child emotionality through poverty-related stress. In addition, negative emotionality was associated with adolescent internalizing symptoms, attention difficulties, and physical health, but not externalizing symptoms, even when controlling for early poverty exposure.
