The present longitudinal study used the traditional cross-lagged panel model (CLPM) and autoregressive latent trajectory model with structured residuals (ALT-SR) to examine the relationships between perceived interparental conflict (IPC), negative thinking (NT), and depression symptoms in Chinese children. Changes in these three variables over time were also examined, as well as the trait and state aspects of the relationships between them. A sample of 516 third-grade primary students completed questionnaires about IPC, NT, and depression three times over a period of 1 year, at 6-month intervals. The CLPM findings indicated that, assuming that stability of each variable across time was controlled, Chinese children’s perception of IPC significantly affected their level of depression through the mediating path of NT. After taking trait factors into account, among all the significant autoregressive and cross-lagged paths originally found in the CLPM, only one third remained significant in the ALT-SR model. More specifically, the ALT-SR model, revealed a driving effect of children’s NT on perceived IPC and depression symptoms. The CLPM model although elucidated the interplay among three variables, the ALT-SR model showed little evidence of their interrelated growth across time. Taken together, these results indicate that children’s perceived IPC in the long term are a stable trait, with few state-level fluctuations, and is not a significant within-person predictor of subsequent children’s internalization problems. These perceptions appear to contribute more to children’s general psychological tendency than do changes over time. The research is the first to test the reciprocal relationships between Chinese children’s perceived IPC, NT, and depression symptoms. The findings demonstrate that previously proposed theories about the bidirectional relation between IPC and children’s social adjustment, to some extent, may reflect a correlation at a trait level. Put another way, it is IPC’s central tendency to be sensitive in the long term as a stable trait that is associated with their children’s general tendency to show well adjustment. The study contributes to our understanding of that extend previous results and have implications for complementary theoretical and practical interventions. The complementary techniques of CLPM and ALT-SR models offer different insights into children’s internalization problems, and hold promise for supporting the building of more comprehensive children’s developmental theories that acknowledge the interconnectedness of different domains of mental health.

BackgroundThe outbreak of COVID-19 epidemic continues to unfold globally, which harms the public’s mental health. Adolescents’ mental health is affected by social isolation and lockdown during the COVID-19 epidemic. The implicit theory of thoughts-emotion-behavior states that individuals with a growth mindset believe that thoughts, emotions, and behaviors can be changed through effort and tend to persist in pursuing higher goals and maintain enthusiasm as well as cope with stress resiliently, thus having higher gritty and levels of mental health. This study aimed to explore the role of grit and coping strategies in the influence of the growth mindset on adolescents’ mental health during the COVID-19 epidemic period.MethodsA total of 1564 participants (Mage = 17.02, 760 boys, 804 girls) from three high schools in China were recruited to complete The Self-report Questionnaire-20, The Growth Mindset Scale, The Short Grit Scale, and The Coping Style Scale to evaluate mental health, growth mindset, grit, and positive coping strategies, respectively.ResultsThe results showed that growth mindset has no significant indirect effect on mental health through grit but has a significant indirect effect on mental health through coping strategies. The results of chain mediation analysis showed that grit and coping strategies play chain mediating roles between growth mindset and adolescents’ mental health.ConclusionThe findings suggest that cultivating a growth mindset, developing grit, and teaching adolescents to adopt positive coping strategies can improve adolescents’ mental health.

BackgroundPrevious studies have demonstrated that destructive interparental conflict (IPC) is closely related to the emergence of emotional and behavioral problems in adolescents. In addition, in the family system, such conflict also affects the patent–child attachment relationship and emotional insecurity of adolescents.ObjectivesThis study mainly explores the relationship between destructive interparental conflict and adolescents’ emotional and behavioral problems, focuses on the role of parent–child attachment and emotional insecurity, and analyzes whether this relationality plays multiple mediating roles in the influence of destructive interparental conflict on emotional and behavioral problems.MethodsData for the study were obtained through a questionnaire survey conducted on 524 Chinese adolescents from primary and junior high school.ResultsStructural equation modeling was conducted to test direct and indirect pathways between destructive interparental conflict and Chinese adolescents’ emotional and behavioral problems. Destructive IPC negatively predicted parent–child attachment and parent–child attachment negatively predicted emotional and behavioral problems. Destructive Interparental conflict positively predicted emotional insecurity and emotional insecurity positively predicted emotional and behavioral problems.DiscussionThe results show that: (1) Parent–child attachment negatively predicted emotional and behavioral problems, and emotional insecurity positively predicted the same. (2) Parent–child attachment and emotional insecurity act in a multiple mediating role between destructive IPC and adolescents’ emotional and behavioral problems. (3) Parent–child attachment and emotional insecurity constitute two indirect pathways between destructive IPC and adolescents’ emotional and behavioral problems, respectively.ConclusionDestructive IPC can adversely affect emotional and behavioral problems among adolescents; destructive IPC plays a damaging role in their emotional security and parent–child attachment, consequently effecting emotional and behavioral problems.
