Parental self-efficacy beliefs develop over time. Most research, however, has focused mainly on the trajectories and predictors of trajectories of maternal self-efficacy, while little is known about those of paternal self-efficacy. This study examined the change in paternal self-efficacy for educational involvement during children's elementary school period, analyzing whether the change is influenced by fathers' long working hours (i.e., work hours on workdays and work hours on nonworkdays) and fathers' perceptions of time and energy. Data from 1,684 Chinese fathers of fourth grade children were collected every half year for two-and-a-half consecutive years. The results of a latent growth curve analysis revealed that paternal self-efficacy for educational involvement increased over the elementary school period. Fathers' working hours on nonworkdays were negatively associated with the initial level of paternal self-efficacy for educational involvement, but this negative effect was nonsignificant after fathers' perceived time and energy were added to the final model. Fathers' perceived time and energy were positively associated with the initial level of paternal self-efficacy for educational involvement and negatively associated with the growth rate of paternal self-efficacy for educational involvement. The findings advance the theory of parental self-efficacy, underlining the need to consider fathers' perceived time and energy to understand changes in paternal self-efficacy for educational involvement.

Background and aims: Adolescent problematic gaming is a global public health issue, and is associated with numerous negative outcomes. The Big Two personality traits, neuroticism and extraversion, have been identified as significant predictors of problematic gaming in adolescents. However, most previous studies have been cross-sectional, limiting the ability to explore their mutual influences or causality inference. This study addresses this gap by employing a longitudinal design and utilizing the Random Intercept Cross-Lagged Panel Model (RI-CLPM) to examine the bidirectional relations between the Big Two personality traits and problematic gaming at the within-person level.Methods: This study included 3,307 students (Mean age = 11.30, SD = 0.48, 43.6% being girls). Participants were assessed annually, completing a total of four assessments over the course of the study.Results: The RI-CLPM analyses revealed that neuroticism and problematic gaming significantly predict each other. Extraversion acts as a protective factor against adolescent problematic gaming, whereas problematic gaming leads to a decrease in extraversion levels. Additionally, the longitudinal relations between neuroticism and problematic gaming exhibit significant sex differences.Discussion and conclusions: This study provides insights into the interplay between the Big Two personality traits and problematic gaming in adolescents. These findings emphasize the need for prevention and intervention strategies that address personality traits as risk factors while recognizing how problematic gaming can influence personality, promoting a more holistic approach. The observed sex differences highlight the importance of integrating sex-specific considerations in interventions.

Background: Parenting stress is a known risk factor for children’s social anxiety, yet the mediating and moderating mechanisms underlying this relationship remain underexplored, particularly regarding gene–environment interactions. This quantitative, cross-sectional study, grounded in diathesis-stress and family process theories, examined whether maladaptive parenting mediates the link between parenting stress and children’s social anxiety, and whether FKBP5 gene variation moderates this mediation. Methods: A sample of 1774 fourth- to sixth-grade students (aged 10–14 years) and their parents participated. Parenting stress and maladaptive parenting were parent-reported, children’s social anxiety was self-reported, and children’s FKBP5-related cumulative genetic score was derived from four SNPs (rs4713916, rs1360780, rs3800373, rs9296158). Moderated mediation analyses were conducted. Results: Parenting stress was significantly and positively associated with children’s social anxiety. Maladaptive parenting partially mediated this relationship. The FKBP5 showed a marginally significant moderating effect, with simple slope analysis suggesting parenting stress was more strongly associated with child social anxiety among children with higher genetic risk. No moderating effect was found for the path from maladaptive parenting to social anxiety. Conclusions: Parenting stress is associated with children’s social anxiety both directly and indirectly through maladaptive parenting, with FKBP5-related cumulative genetic risk potentially moderating the direct effect. These findings offer preliminary evidence that may inform preventive interventions targeting parenting stress, although replication is needed.
