Environmental susceptibility for all: A data-driven approach suggests individual differences in domain-general and domain-specific patterns of environmental susceptibility

Temperament and sex as moderating factors of the effects of exposure to maternal depression on telomere length in early childhood

Individual differences in sensitivity to context are posited to emerge early in development and to influence the effects of environmental exposures on a range of developmental outcomes. The goal of the current study was to examine the hypothesis that temperament characteristics and biological sex confer differential vulnerability to the effects of exposure to maternal depression on telomere length in early childhood. Telomere length has emerged as a potentially important biomarker of current and future health, with possible mechanistic involvement in the onset of various disease states. Participants comprised a community sample of children followed from infancy to age 3 years. Relative telomere length was assessed from DNA in saliva samples collected at infancy, 2 years, and 3 years. Maternal depressive symptoms and the child temperament traits of negative affectivity, surgency/extraversion, and regulation/effortful control were assessed via maternal report at each timepoint. Analyses revealed a 3-way interaction among surgency/extraversion, sex, and maternal depressive symptoms, such that higher surgency/extraversion was associated with shorter telomere length specifically among males exposed to elevated maternal depressive symptoms. These findings suggest that temperament and sex influence children's susceptibility to the effects of maternal depression on telomere dynamics in early life.

Daily Interplay of Positive and Negative Events with Adolescents' Daily Well-Being: Multilevel Person-Centered and Variable-Centered Approaches

INTRODUCTION

This study examined associations between adolescents' daily negative and positive events and their coping efficacy, an understudied topic but pivotal to adolescent thriving.

METHODS

The sample included 153 parent-adolescent triads; adolescents' mean age, 15.71 years (SD = 1.53), 51% girls. Parents were in their midlife (Mage mother = 47.82, SD = 4.90; Mage father = 50.39, SD = 5.80). The study used a daily diary methodology to test within-person links to establish a temporal order of effects. Over seven consecutive days, adolescents reported on 14 daily negative and positive events. Adolescents, mothers, and fathers reported on adolescents' daily coping efficacy.

RESULTS AND CONCLUSIONS

Multilevel latent profile analysis (MLPA) identified 4 day-level event profiles: "low event day" (34% of days), reflecting low levels of both positive and negative events and low coping efficacy and positive and negative mood; "positive day" (44%), reflecting dominance of intense positive events and corresponding high coping efficacy and positive mood; "mixed day," reflecting a combination of intense positive and negative events with average coping efficacy and positive mood despite high negative mood and impaired coping. Multilevel path analysis showed adolescents reported increased coping efficacy a day after increased academic load, and parents reported increased adolescent coping efficacy a day after positive parent-adolescent interactions. Fathers reported decreased adolescent coping efficacy a day after peer disappointment. Findings suggest positive events predominate in adolescents' lives, and their coping efficacy is sensitive to dynamic changes in the valence of context.

How do fathers' educational level contribute to children's school problems? Overparenting and children's gender and surgency in a moderated mediation model

This study aims to investigate (a) the mediating role of overparenting between father's educational level and children's school problems, and (b) the joint moderating role of children's gender and surgency in the indirect relationship between father's educational level and school problems. Participants were 203 school children, 96 boys (47.3%) and 107 girls (52.7%), aged 7-8 years (M = 92.42 months, SD = 3.52). Fathers reported their educational level, age and employment status and their children's gender and number of siblings, as well as their overparenting behaviors by Anticipatory Problem Solving (APS) scale. Teachers informed children's school problems by the Behavior Assessment System for Children (BASC T-2). Parents together informed their children's surgency levels by a subscale of Children's Behavior Questionnaire (CBQ). Results showed that, in girls, the father's educational level was negatively related to the child's school problems via overparenting behaviors, controlling the number of siblings and father's age and employment status. However, among boys, fathers' overparenting protect their shy sons from the risk of a low educational level for school problems. These findings highlight the relevance of considering the gender and surgency to a better understanding of the effects of contextual factors on children's outcomes.
