Problematic Internet use (PIU) is currently becoming a more serious public health concern, representing a deleterious effect on adolescent adaptive emotional and behavioral patterns. Given the prevalence of PIU and its deleterious impact on adolescents’ optimal functioning, it is valuable to investigate the risk and protective factors of PIU. Guided by a socio-ecological framework, the current study examines the associations of paternal attachment and maternal attachment with PIU among Chinese adolescents. Furthermore, this study investigates whether adolescents’ gender and grit moderate this association. A total of 2677 Chinese adolescents (56.5% girls; Mage = 15.56; SD = 1.57) was involved in this study. Adolescents were uniformly instructed to complete a battery of self-reported questionnaires. The results of linear regression analyses showed that paternal attachment and maternal attachment security were negatively related to PIU. Moreover, moderation analyses revealed that higher levels of grit buffered against boys’ PIU in the context of paternal attachment security and girls’ PIU in the context of paternal attachment insecurity. The current study suggests that parental attachment security plays an important role in mitigating the likelihood of Chinese adolescents’ PIU. Moreover, the buffering role of grit in PIU varies by the levels of paternal attachment security, depending on the adolescents’ gender.

This study explored whether social support moderated the relationship between various symptoms of posttraumatic stress disorder (PTSD) and antisocial behavior. Participants were 597 adolescents from two middle schools in Lushan county, China, an area severely affected by the Ya'an earthquake. All four symptom clusters of PTSD significantly and positively correlated with antisocial behavior. Of the PTSD symptoms, only social support played a significant moderating role in the effects of intrusion and avoidance symptoms on antisocial behavior. Intrusion and avoidance symptoms were associated with more antisocial behavior for individuals with lower social support.

The present study examined the relationships between bullying, trauma‐related guilt, trauma‐related shame, and prosocial behaviors. We investigated 1,322 college students using a longitudinal approach to explore the internal mechanism between bullying, prosocial behaviors, and the probable mediating effects of trauma‐related guilt and shame. The results suggested that bullying negatively predicted prosocial behaviors and that trauma‐related guilt played a positive mediating role. In contrast, trauma‐related shame played a negative mediating role in the relationship between bullying and prosocial behaviors. These findings indicated that trauma‐related guilt and shame played adaptive and maladaptive roles after bullying victimization, which also provided a theoretical basis for the relevant intervention.

Objective To analyze the pathways and mechanisms underlying the impact of guilt on suicide risk using a well‐controlled longitudinal study, we examined the mediating roles of intrusive rumination, deliberate rumination, and posttraumatic stress disorder (PTSD) in this association. Method Four hundred and eight adolescent survivors (Mage = 14.05 years) were assessed using self‐report questionnaires three and a half years and four and a half years after the Ya'an earthquake. The self‐report questionnaires included the Trauma Exposures Questionnaire, the Interpersonal Guilt Questionnaire, the Event‐Related Rumination Inventory, the PTSD Checklist for the DSM‐5, and the Child Behavior Problems Questionnaire. Results The results indicated that guilt had a direct and positive effect on suicide risk. Intrusive rumination and PTSD mediated the relationship between guilt and suicide risk. Guilt could increase deliberate rumination, but deliberate rumination did not significantly predict PTSD and suicide risk. Conclusion Negative postdisaster emotions, such as guilt, can enhance the combined effects of cognition and psychological disorders on suicide risk. Guilt affects suicide risk indirectly through intrusive rumination and PTSD but not through deliberate rumination.
