Pubertal timing and self-esteem in adolescents: The mediating role of body-image and social relations

Am I a good person? Academic correlates of explicit and implicit self-esteem during early childhood

Implicit and explicit self-esteem are not commonly measured in the same children. Using a cross-sectional design, data from 354 Croatian children (184 girls) in Grade 1 (Mage = 7.55 years) and Grade 5 (Mage = 11.58 years) were collected in Spring 2019. All children completed explicit and implicit self-esteem measures; math and language grades were obtained. For the explicit measure, older children showed lower self-esteem than younger children, and girls showed lower self-esteem than boys. For the implicit measure, there were no age effects, and girls showed higher self-esteem than boys. Although both types of self-esteem were positively associated with academic achievement, implicit self-esteem was associated more strongly with language than with math achievement. Discussion is provided about why self-esteem relates to academic achievement during childhood.

Associations between parenting characteristics and adolescent substance use: A genetically informed, longitudinal adoption study

The present study examined putative environmental predictors of adolescent substance use, using a prospective adoption design to distinguish between environmental mediation (i.e., parenting influencing adolescent substance use), passive gene-environment correlation (i.e., parental genetic predisposition influencing the association between parenting characteristics and adolescent substance use), and evocative gene-environment correlation (i.e., children's genetic predisposition influencing parenting). Longitudinal data from the Colorado Adoption Project (395 adoptees, 491 nonadoptees, 485 adoptive parents, and 490 biological parents) were examined. Children (48% girls) were assessed at ages 1 to 17 years. Over 90% of the sample were non-Hispanic White. Associations between parenting and adolescent substance use were compared between adoptive and nonadoptive families. Positive, negative, and inconsistent parenting measures in early childhood through adolescence were not consistently associated with adolescent substance use, with only 6% of correlations being statistically significant (r = -0.152 to .207). However, parent-child relationship quality assessed from childhood to adolescence and orientation to parents assessed during adolescence were significantly, negatively associated with adolescent substance use, with 71% of correlations being statistically significant (r = -0.88 to -0.11). There was little evidence of sex differences in the associations. Environmental mediation, rather than passive or evocative gene-environment correlation, explained most associations.

Nonproductive thoughts, somatic symptoms and well-being in adolescence: testing the moderator role of age and gender in a representative study

Background

Previous findings suggest a female preponderance in nonproductive thoughts -rumination and worry-, but studies on gender differences in the strength of the relationship between nonproductive thoughts, somatic symptoms and subjective well-being are scarce. Our aim was to test whether gender and age would moderate these associations.

Methods

1572 adolescents were involved in this representative cross-sectional study (770 boys; mean age = 15.39; SD = 2.26 years). Nonproductive thoughts were measured by Nonproductive Thoughts Questionnaire for Children (NPTQ-C), somatic symptoms were assessed by Somatic Complaint List (SCL), while Mental Health Continuum-Short Form (MHC-SF) was used to measure subjective well-being. To assess the moderation effects of age and gender on the relationship between nonproductive thoughts, somatic symptoms and well-being, four multiple indicator multiple causes (MIMIC) models were defined.

Results

Our results suggested that higher rates of nonproductive thoughts predicted a higher level of somatic symptoms and a lower level of subjective well-being. The analyses revealed that although nonproductive thoughts were strongly and equally associated with somatic symptoms among boys and girls, age was a significant moderator. Gender also moderated the relationship between nonproductive thoughts and subjective well-being.

Conclusions

Our results support the importance of nonproductive thoughts in somatic symptoms and highlight that the strength of the relationship is similar across both genders but could be dependent upon age. The findings also shed light on the decreased well-being of girls, especially with elevated level of nonproductive thoughts.
