Summary: This study is the first attempt to investigate the relationship between two forms of bullying victimization and suicidal ideation. The results showed that rumination plays an important mediating role in the relationship between different forms of bullying victimization and suicidal ideation, while the mediating effect of insomnia was not significant in the relationship between traditional bullying victimization and suicidal ideation, but was significant in the relationship between cyberbullying victimization and suicidal ideation. Furthermore, both rumination and insomnia had significant chain mediating effects between different forms of bullying victimization and suicidal ideation.

Summary: In recent years, the high suicide rates among victims of bullying have become a major concern. Suicide is a leading cause of preventable death among adolescents, emphasizing the importance of identifying signs of suicidal behavior in victims. This study examined the impact of victims' silence and the role of family and school environments. The results showed that parental rejection and indifference were linked to victims' non-disclosure and suicidal ideation, while a positive school climate had a negative relationship with disclosure and ideation. Non-disclosure was found to mediate the relationship between the mother's parenting style and suicidal ideation. These findings contribute to our understanding of the social context and disclosure in relation to suicidal thoughts among adolescents who experience bullying.

Summary: Children with persistent or rising irritability are at a higher risk of suicide attempt in adolescence, with peer victimization playing a key mediating role. Harsh parenting, however, does not appear to mediate the association between irritability and suicide attempt. These findings suggest that interventions targeting peer victimization may help reduce suicide risk in irritable children.

Summary: This study investigated the prevalence of suicide planning and attempt among individuals with suicidal ideation, as well as their associations with sociodemographic characteristics, mental disorders, adverse childhood events, and prior suicidal behavior. The results showed that the prevalence of suicide planning and attempt were 17.7% and 10.6% respectively, with over 80% occurring within a year of the suicidal ideation. Suicide planning was more likely among those with mood disorders, while suicide attempt was more likely for those who were currently married, had lower educational qualifications, history of anxiety disorders, history of emotional neglect, and parental separation.

Summary: The objective of this study was to examine the mediating role of emotional intelligence, interpersonal difficulties, and life satisfaction in the relationship between victimization and suicidal ideation. The results revealed that these factors played a significant mediating role in the association between bullying victimization and suicidal thoughts. Furthermore, the findings indicated that the association between emotional intelligence and suicidal ideation was moderated by gender and age. Additionally, the study found that emotional intelligence had a stronger effect on reducing suicidal thoughts in students who had not retaken a course in cases of relational victimization.

Summary: This meta-analysis found that suicidal ideation (SI) and suicide attempt (SA) are common among patients with traumatic brain injury (TBI). The prevalence of SI and SA in TBI patients was 19.1% and 2.1%, respectively. The prevalence of SA in Asian and non-Asian countries was similar. The publication year and age were positively associated with the pooled prevalence of SI, while the geographical location of the institution, sample size, and age were negatively associated with the pooled prevalence of SA.

Summary: Suicide is an important public health issue. A study found that adolescents with a history of suicidal attempts faced greater difficulties in social relations, risky behaviors, and had more intense suicidal ideation compared to those with suicidal ideation only. The use of MMPI-A to assess certain features may help identify young people at high risk of suicide.

Summary: This study examined whether having a genetic predisposition to depression increased the risk of experiencing depressive symptoms in peer victimised youth. The results showed that both self- and teacher-reported peer victimisation were associated with depressive symptoms in adolescence, and this association remained significant when accounting for genetic predisposition. However, there was no significant interaction between genetic predisposition and peer victimisation. The findings suggest that genetic predisposition and exposure to peer victimisation are independently associated with depressive symptoms in adolescence.

Summary: Research aims to fill the knowledge gap in adolescent polysubstance use and determines the better explanation for cannabis use outcomes in early adulthood. It finds that youth with early-onset cannabis use show distinct polysubstance use profiles, and those who follow an escalating or frequent (with cigarettes) pattern have consistently higher cannabis use frequency and problems compared to those who started later in adolescence or adulthood.

Summary: Eating disorders have early origins and there may be a link between childhood eating behaviors and long-term disordered eating. Factors such as BMI, desire for thinness, and peer victimization could influence this link, but the exact mechanisms are unknown. To address this knowledge gap, the study used data from the Quebec Longitudinal Study of Child Development and found that a significant percentage of youth had a trajectory of high disordered eating from 12 to 20 years old. The findings highlight the importance of promoting healthy body images and eating behaviors among young people.

Summary: A study of 36,516 parents from six international cohorts reveals associations between parental genetics and parental investments in offspring, from behaviors during pregnancy to wealth inheritance in adulthood. The effects of parental genetics on behaviors tend to be small at any given time point, but accumulate over development. This suggests that parents pass on advantages to their children through genetic associations with investments across various stages of development.

Summary: This study examined the structure of psychopathology in mid-adolescence using symptom dimensions and found that a bifactor model provided the best fit. The bifactor model consisted of a general psychopathology factor and specific internalizing, externalizing, or substance use factors. Additionally, the study found that the general psychopathology factor (P factor) was associated with various mental health disorders and alcohol use disorder at 20 years. The results suggest that targeting the common liability to psychopathology may be important in preventing later mental health problems and AUD.
