Associations between parents' adult attachment, Co-parenting and parent-child relationships: an actor-partner interdependence model.

This study used the Actor-Partner Interdependence Model to examine how parents' adult attachment influences their their own and the partners' co-parenting and parent-child relationships. Participants were from a cross-sectional sample of 1313 Chinese heterosexual married couples (fathers' Mage = 39.74, SD = 5.61; mothers' Mage = 37.55, SD = 5.04) whose biological children were pupils (Mage = 10.25, SD = 2.35). Results revealed that: (a) Couple members' actor effects from adult attachment avoidance to positive and negative co-parenting and parent-child closeness and conflict were found both significant; (b) The actor effects from adult attachment anxiety to negative co-parenting and parent-child conflict were found significant, whereas only partner effect from attachment avoidance to positive co-parenting and from attachment anxiety to parent-child conflict were significant. The results highlight the negative effects of parents' attachment avoidance and anxiety on their partners' parenting function.

Longitudinal Associations between Future Time Perspective, Sleep Problems, and Depressive Symptoms among Chinese College Students: Between- and within-Person Effects.

Depressive symptoms and sleep problems are extremely prevalent in adolescence, and future time perspective has been found to be strongly associated with them. However, little is known about the longitudinal relationship and the temporal dynamics of future time perspective, sleep problems, and depressive symptoms. Moreover, it is unclear whether sleep problems mediate the associations between future time perspective and depressive symptoms. To address this gap, a one-year longitudinal study was performed using data collected at three waves from 622 Chinese college students (aged 17-22 years, Mage = 18.16, SD = 1.49, 46.95% males). The results of cross-lagged panel models showed a bidirectional relationship between future time perspective and depressive symptoms, and that sleep problems were a mediating mechanism for these relationships. The results of random intercept cross-lagged panel models showed that at the within-person level, the change of sleep problems and depressive symptoms significantly affected the development of future time perspective, but the reverse effect not significant. Moreover, sleep problems mediated the within-person effect of depressive symptoms on future time perspective. These findings deepen the understanding of the longitudinal relationship between future time perspective, sleep problems and depressive symptoms, and emphasize the important role of sleep health in adolescent mental health and future development.

Competitive Video Game Exposure Increases Aggression Through Impulsivity in Chinese Adolescents: Evidence From a Multi-Method Study.

It is widely known controversies about the results of violent video game increase aggression. However, the role of competitive video games, has received less research attention, and the underlying mechanisms of their influence are unknown. This study aimed to expand the existing literature by systematically exploring the effects of competitive video game exposure on adolescent aggression and the mediating role of impulsivity. In so doing, three types of studies (collectively N = 2919, mean age varied from 13.75 to 15.44 years, with a balanced gender) combining cross-sectional, experimental, and longitudinal approaches, were conducted. The findings consistently show that competitive video game exposure increased adolescents' aggression and impulsivity. Also, impulsivity mediated the correlation and long-term effect of competitive video game exposure on aggression. However, the experimental study did not confirm the short-term mediating effect of impulsivity, which may be related to the type of aggression measured in the study. The results indicate that competitive video game exposure is an important antecedent factor for adolescent aggression, and impulsivity is the key underlying mechanism.

The Effects of Family and School Interpersonal Relationships on Depression in Chinese Elementary School Children: The Mediating Role of Academic Stress and the Moderating Role of Self-Esteem.

This study explores the relative contributions and psychological mechanisms of the effects of family (father-child and mother-child) and school (teacher-student and student-student) interpersonal relationships on depression in elementary school children. The participants (n = 20,629) were elementary school children (48.19% male) aged nine to 13 years from Southwest China during the COVID-19 pandemic. They voluntarily completed questionnaires regarding parent-child, teacher-student, and student-student relationships, as well as academic stress and self-esteem. The results indicate that the effect of family interpersonal relationships on children's depression was stronger than that of school interpersonal relationships. The predictive effects of father-child and mother-child relationships on children's depression did not significantly differ; however, the effect of student-student relationships was significantly stronger than that of teacher-student relationships. Academic stress partially mediated the effect of interpersonal relationships on depression in elementary school children. The effects of family interpersonal relationships and academic stress on depression were moderated by self-esteem. These findings underscore the disparities and mechanisms pertaining to the impacts of diverse interpersonal associations on children's depression, thus signifying significant implications for the advancement of research and intervention strategies aimed at addressing this issue.

Bidirectional relations between problematic smartphone use and bedtime procrastination among Chinese university students: Self-control as a mediator.

OBJECTIVE: Based on theoretical and empirical evidence, this study examined the longitudinal relationship between problematic smartphone use and bedtime procrastination and the potential mediating role of self-control. METHODS: Between November 2021 and November 2022, a three waves longitudinal design was employed. Wave 1 included 622 Chinese college students (46.95% male, Mage = 18.16, SD = 0.73), with 6-month intervals between waves. The data was collected using self-report assessments. RESULTS: The results of the cross-lagged panel models show that problematic smartphone use positively predicted later bedtime procrastination, and the bedtime procrastination also positively predicted later problematic smartphone use among college students. More importantly, self-control played a mediating role in their bidirectional predictive relationship. CONCLUSIONS: These findings add to the understanding of the causal relationship between problematic smartphone use and bedtime procrastination and reveal the core psychological mechanisms underlying their vicious cycle, with important practical implications for the prevention and intervention of problematic smartphone use and sleep problems.
