Trajectories of peer victimization among left-behind children in rural China: The role of positive school climate.

Left-behind children are likely to experience peer victimization, which can have detrimental consequences in their developmental outcomes. Yet, limited longitudinal research have examined peer victimization trajectories over time or the factors associated with left-behind children in China. The purpose of the present study was to examine what, if any, distinct trajectories of peer victimization exist among left-behind children and whether these trajectories are related to school climate, left-behind status, and their interactions. Participants were 853 Chinese left-behind children (Mage = 14.25, SD = 2.39; 43.4% girls) who participated in a four-wave longitudinal study conducted in rural China. Participants reported school climate (indexed by safety and order, acceptance and support, equality and fairness, autonomy and cooperation) at T1 and peer victimization across T1 to T4 spanning 2 years. Latent class growth analyses identified four peer victimization trajectories, including a stably low-decreasing group, a moderate-decreasing group, a high-decreasing group, and an increasing group. Multinomial logistic regression analyses revealed that children who perceived more positive school climate were more likely to exhibit a stably low-decreasing trajectory compared to the other three groups. In addition, among left-behind children who perceived more positive school climate, children with single-parent migrating were more likely to be members of the stably low-decreasing group as compared to those with both-parent migrating. Peer victimization among left-behind children is a concern especially for those who were left behind by both parents and perceived less positive school climate. Targeted school-based interventions and services focused on reducing peer victimization and improving school climate are needed for left-behind children, especially those with both-parent migrating.

Longitudinal Trajectories of Social Mobility Beliefs among Chinese Adolescents: The Protective Roles of Parental Academic Involvement and Adolescent Future Orientation.

Social mobility beliefs play a significant role in shaping adolescents' adaptive developmental outcomes, including well-being and academic functioning. Nevertheless, existing research may not cast light on the distinct trajectories and potential protective factors of social mobility beliefs. The present study aims to identify heterogeneity in trajectory patterns of social mobility beliefs among Chinese adolescents (Mage = 12.45, SDage = 2.60; 55.1% boys; 40.0% rural adolescents) in a four-wave (i.e., fall 2017, fall 2018, spring 2019, and fall 2019) longitudinal design, and examines the protective roles of parental academic involvement and adolescent future orientation. Three distinct trajectories of social mobility beliefs were identified: high-increasing (35.1%; a positive trajectory with the best developmental outcomes, including the lowest problem behaviors and depression symptoms, and the highest life satisfaction and academic competence), moderate-stable (49.8%), and low-decreasing (15.1%; a negative trajectory with the worst developmental outcomes, including the highest problem behaviors and depression symptoms, and the lowest life satisfaction and academic competence). Apart from the main effects of parental academic involvement and future orientation, a significant interaction effect of these two protective factors and adolescent group was detected, and only rural adolescents who reported both high levels of parental academic involvement and future orientation have a greater chance of being placed in the high-increasing trajectory than the low-decreasing trajectory. These findings highlight the significance of clarifying individual differences in the dynamic process of social mobility beliefs during adolescence, and elucidate rural-urban disparities in the influences of protective factors on social mobility beliefs trajectories, and inform individualized intervention strategies.

Developmental Trajectories of Mental Health in Chinese Early Adolescents: School Climate and Future Orientation as Predictors.

There is growing support for the dual-continua model of mental health, which emphasizes psychopathology and well-being as related but distinct dimensions. Yet, little is known about how these dimensions co-develop from childhood to early adolescence and what factors predict their different trajectories. The current study aimed to identify distinct patterns of mental health in Chinese early adolescents, focusing on both psychopathological symptoms (i.e., depressive symptoms and self-harm behaviors) and subjective well-being (i.e., life satisfaction and affect balance). This study also examined the contributions of school climate and future orientation to these trajectories. A total of 1,057 students (Mage = 11.88, SDage = 1.67; 62.1% boys) completed four assessments over two years, with six-month intervals. Using parallel-process latent class growth modeling, we identified four groups: Flourishing (32.5%), Languishing (43.8%), Troubled with Stable Depressive Symptoms (16.1%), and Troubled with Increasing Self-Harm Risk (7.6%). Furthermore, school climate and future orientation contributed to adolescents' membership in these trajectories, either independently or jointly. Specifically, higher levels of future orientation combined with higher school climate were associated with a lower likelihood of belonging to the Troubled with Increasing Self-Harm Risk trajectory, compared to the Flourishing group. Our findings identified four distinct mental health trajectories consistent with the dual-continua model, and demonstrated that the development of psychopathology and well-being were not always inversely related (e.g., the Languishing group). Adolescents with unique developmental profiles may benefit from tailored intervention strategies that build on the personal and environmental assets of the adolescent.

Reciprocal associations between peer victimization and depressive symptoms among Chinese children and adolescents: Between- and within-person effects.

Peer victimization is detrimental to child mental health. Research has indicated a reciprocal relationship between peer victimization and mental health problems. Yet limited evidence was from children and adolescents in China. The present study used the random intercepts cross-lagged panel model (RI-CLPM) to examine both between-person and within-person associations between peer victimization and depressive symptoms among Chinese children and adolescents. Participants were 1205 Chinese students (Mage = 11.27 years; ranged from 9 to 15 years; SD = 1.75; 55% boys) who completed four surveys (Time 1 to Time 4) between 2017 and 2019 on demographics, peer victimization, and depressive symptoms. At the between-person level, peer victimization was positively associated with depressive symptoms. Controlling for between-person effects, RI-CLPM suggested positive within-person effects from peer victimization to depressive symptoms across adjacent waves. The model also suggested a positive within-person effect from Time 2 depressive symptoms to Time 3 peer victimization. The multi-group analysis showed that these effects did not differ by gender, age, or subjective socioeconomic status. Peer victimization and depression appear to be reciprocally related at the transitioning period between late childhood and early adolescence in Chinese students. Mental health interventions should attend to peer victimization for children and adolescents in China.

Developmental Trajectories of Adolescent Internet Addiction: Interpersonal Predictors and Adjustment Outcomes.

Despite the burgeoning literature on adolescent internet addiction (IA), the majority of studies have relied on cross-sectional designs and variable-centered analytical approaches. Therefore, little is understood about the heterogeneous developmental trajectories of adolescent IA as well as its antecedents and outcomes. This longitudinal study adopted growth mixture modeling (GMM), a person-centered approach, to identify the distinct trajectories of IA among adolescents during a three-year period. We further examined the interpersonal predictors along with a series of outcomes of different trajectories. Participants included 1,365 Chinese adolescents (Mage = 14.68 years, SD = 1.56; 46.8% girls) from two junior high schools and two senior high schools. The GMM results indicated three distinct trajectories: low-increasing (56.7%), moderate-declining (37.6%), and high-declining (5.7%) groups. In terms of interpersonal predictors, adolescents who reported poorer relationships with their parents, teachers, and schoolmates were more likely to belong to the high-declining and moderate-declining groups. In terms of outcomes, the high-declining and moderate-declining groups exhibited an increase in mental health problems (i.e., more depressive symptoms, lower self-esteem, and lower subjective well-being) and delinquent behaviors, even after controlling for their baseline levels. These findings highlight the heterogeneity of IA trajectories among adolescents, the predictive role of interpersonal factors, and different adjustment outcomes associated with IA trajectories. Therefore, prevention and intervention programs involving interpersonal relationships may be promising for adolescents at high or moderate risk of IA.

Cortisol Reactivity as a Mediator of Peer Victimization on Child Internalizing and Externalizing Problems: The Role of Gender Differences.

Children exposed to peer victimization are at increased risk for psychopathology. However, the physiological mechanisms linking peer victimization to child psychopathology and the potential gender differences in these links remain inadequately understood. The present study examined whether cortisol reactivity to acute stress mediated the associations between relational and physical victimization and internalizing and externalizing problems and whether these associations differed between boys and girls. A sample of 150 Chinese children (aged 9-13 years; Mage = 10.69 years; 51% boys) reported experiences of relational and physical victimization and participated in a standardized laboratory psychosocial stress task, during which six salivary cortisol samples were collected. Parents or primary caregivers reported their children's internalizing and externalizing problems. Overall, neither physical nor relational victimization was associated with cortisol reactivity. However, when examined separately by gender, relational victimization was associated with blunted cortisol reactivity for boys but not for girls. Further, among boys but not girls, relational victimization was indirectly associated with internalizing and externalizing problems via blunted cortisol reactivity. Our findings suggest that blunted cortisol reactivity may serve as a physiological pathway linking peer victimization to psychopathology for boys but not for girls.

Latent profiles and transition of perceived parental control and their relationship with the psychosocial well-being among rural-to-urban migrant adolescents.

The present study examined what, if any, patterns of parental control are associated with multiple indicators of psychosocial well-being and whether changes in these patterns over time predict subsequent psychosocial well-being. Latent profile analyses and latent transition analyses were applied to identify subgroups of parental control and transitions of these patterns over time among rural-to-urban migrant adolescents who participated in two waves of surveys with 6-month interval in 2014 (NT1  = 660, NT2  = 553). Multivariate logistic regression was conducted to explore their relationship with psychosocial well-being. Four latent profiles were identified based on levels of parental control at wave 1 and wave 2, respectively. The high psychological and behavioral control (HPHB) group was associated with worse psychosocial well-being whereas the low psychological control and high behavioral control (LPHB) group exhibited opposite relationships. Six transitioning groups were identified: "stably low-risk" (14.92%), "stably medium-risk" (7.37%), "stably high-risk" (24.49%), "floating LPHB" (26.52%), "high-decreasing" (15.10%), and "low-increasing" (11.60%) groups. The "stably high-risk" and "low-increasing" groups showed a higher risk in psychosocial well-being. Youth exhibiting higher risks of parental control (i.e. individuals in HPHB groups and higher-risk transition patterns over time) should prioritize for interventions and services.

The role of stressful life events and the Big Five personality traits in adolescent trajectories of problematic Internet use.

Cross-sectional studies have shown that both stressors and personality vulnerability are risk factors for adolescent problematic Internet use (PIU). However, little is known about how both categories of factors in combination may contribute to the longitudinal development of PIU among adolescents. The aims of this study were to document the developmental pattern of PIU among adolescents and to examine how stressful life events and the Big Five personality traits jointly affect the development of PIU. We tested three competing models: the additive, diathesis-stress, and social push models. A total of 1,365 adolescents participated in a 3-year longitudinal study. Hierarchical linear modeling indicated that PIU among adolescents increased over the 3-year period. After controlling for demographics and the Big Five personality traits, stressful life events (a time-varying predictor) were positively correlated with the initial level of, and the rate of change in, PIU. After controlling for demographics and stressful life events, four of the time-invariant Big Five personality dimensions had a significant effect on the initial level of PIU. Low Agreeableness, low Conscientiousness, high Openness, and high Neuroticism were positively associated with high initial PIU. In addition, Extraversion was negatively associated with and Conscientiousness was positively associated with the rate of change in PIU. The interaction effect between the personality and stressors was not significant. Therefore, the data provided support for the additive model, indicating that stressful life events and personality dimensions each make a unique contribution to PIU and that both should be considered in the prevention of adolescent PIU.
