Abstract
BACKGROUND Little is known about the mechanism between interpersonal stressors and social anxiety in college students. This study was to investigate the mediating effect of interpersonal sensitivity between interpersonal stressors and social anxiety. METHODS The data was taken from a large-scale health-related cohort among Chinese college students. This study used data from the first four waves, including 4191 participants. The latent growth curve mediation model was used to examine the potential mediating role of interpersonal sensitivity in the relationship between interpersonal stressors and social anxiety over time. RESULTS Both levels and changes in interpersonal stressors were positively associated with subsequent levels and changes in social anxiety. Mediation analysis showed that interpersonal sensitivity mediated the relationship between interpersonal stressors and social anxiety. LIMITATION All variables were collected based on self-report. CONCLUSIONS Interpersonal stressor is a significant risk factor for social anxiety, and this association appears to be mediated by interpersonal sensitivity. It is necessary to evaluate and intervene against interpersonal sensitivity related to interpersonal stressors for the prevention of social anxiety.

Abstract
The long-term effects of the COVID-19 pandemic have caused severe mental health problems among college students, which can eventually cause suicidal ideation. Therefore, through network analysis, this study aims to explore the new characteristics of the depression-anxiety symptom network that arose during the long-term lockdown of the COVID-19 pandemic and to identify the most influential symptoms linked to suicidal ideation. We used a Patient Health Questionnaire (PHQ-9) score above 10 as the cutoff and screened 622 participants with an inclination toward depressive disorders from 7976 college students, and then divided the sample into suicidal and nonsuicidal groups based on the presence or absence of suicidal ideation. The General Anxiety Disorder scale (GAD-7) was also used. Network analysis was used to identify the network structure of anxiety-depression and which symptoms were directly related to suicidal ideation in the network. The prevalence of depression and anxiety among Chinese college students in the late stage of the COVID-19 pandemic was 7.8% and 17.8%, respectively. The most central symptoms in the nonsuicidal group were "excessive worry," "uncontrollable worry," and "nervousness," and in the suicidal group they were "excessive worry," "motor function," and "irritability." The network of the suicidal group was denser than that of the nonsuicidal group. The most influential symptom directly related to suicidal ideation was "guilt." The most influential central symptom of depression-anxiety comorbidity characteristics of Chinese adolescents showed a tendency to shift from depression-oriented (i.e., sad mood) to anxiety-oriented (i.e., excessive worry) with the continuation of the COVID-19 pandemic. Treatments or interventions focused on these critical symptoms could be useful in preventing college students from suicide risk.

Abstract
Interpersonal stress during adolescence and young adulthood can threaten healthy developmental trajectories. A "primed" proinflammatory response to acute stress may serve as an underlying process that results in negative outcomes for youth. The present pilot study examined the relation between interpersonal stress and two proinflammatory cytokines in a sample of 42 university-recruited emerging adults with recent suicidal thoughts and behaviors. Participants completed self-report measures of mood, suicidal thoughts and behaviors, recent peer-related stressors, and interpersonal sensitivity. They also participated in an acute laboratory social stress task and provided three saliva samples to measure their proinflammatory responses (IL-6 and TNF-α) to the stressor. Participants reported significant increases in sadness and exclusion, and significant decreases in inclusion, following task participation. Importantly, no participants reported an increase in or onset of suicidal thoughts. No significant associations between interpersonal stress and proinflammatory cytokines were found. Changes in affect during the task coupled with lack of increased suicidal thoughts indicate it is acceptable to use this exclusion and rejection paradigm with this population, with proper debriefing and positive mood induction procedures. Given all other nonsignificant associations, future research considerations are discussed, including impact of COVID-19 on task potency and incorporation of multiple stress response systems.

Abstract
BACKGROUND There is a complex and inconsistent relationship between bullying involvement and self-harmful thoughts and behaviour (SHTB) in young people. This novel systematic review aims to establish key interacting, moderating and mediating variables associated with SHTB in young people involved in bullying. METHODS The systematic review was registered with PROSPERO: CRD42020192023. A search was conducted (until February 2021) across databases: PubMed/MEDLINE, EMBASE, PsycINFO (Ovid), Cochrane Library, Scopus (Elsevier), Web of Science, ERIC and CINAHL (EBSCOhost). Observational studies containing quantitative primary or secondary data analyses were included in the review, on the basis that they examined interactions, moderators, or mediators between bullying involvement and SHTB in young people. Versions of the Newcastle-Ottawa Scale were used to assess risk of bias in the included studies. RESULTS A total of 57 studies were included. Overall, 3 studies identified interactions, 25 studies identified moderators and 21 studies identified mediators. 9 studies identified moderator-mediators. The findings were categorised as either self-harmful thoughts or self-harmful behaviours and synthesised under the following themes: socio-demographic; depression; parental; personality/psychological; and social/environmental. LIMITATIONS This review uncovered significant heterogeneity and a paucity of replicated studies in the field, therefore, tentative conclusions have been drawn. CONCLUSIONS This comprehensive review highlights the key role of depression as a mediator between traditional/cyber victimisation and SHTB in young people. The moderating effects of gender on mediation models investigating the role of depression suggest the possibility that females involved in bullying may be at increased suicide risk.

Abstract
Bullying victimization is a form of psychological stress that is associated with poor outcomes in the areas of mental health and learning. Although the emotional maladjustment and memory impairment following interpersonal stress are well documented, the mechanisms of complex cerebral dysfunctions have neither been outlined nor studied in depth in the context of childhood bullying victimization. As a contribution to the cross-disciplinary field of developmental psychology and neuroscience, we review the neuropathophysiology of early life stress, as well as general psychological stress to synthesize the data and clarify the versatile dynamics within neuronal networks linked to bullying victimization. The stress-induced neuropsychological cascade and associated cerebral networks with a focus on cognitive and emotional convergence are described. The main findings are that stress-evoked neuroendocrine reactivity relates to neuromodulation and limbic dysregulation that hinder emotion processing and executive functioning such as semantic cognition, cognitive flexibility, and learning. Developmental aspects and interacting neural mechanisms linked to distressed cognitive and emotional processing are pinpointed and potential theory-of-mind nuances in targets of bullying are presented. The results show that childhood stress psychopathology is associated with a complex interplay where the major role belongs to, but is not limited to, the amygdala, fusiform gyrus, insula, striatum, and prefrontal cortex. This interplay contributes to the sensitivity toward facial expressions, poor cognitive reasoning, and distress that affect behavioral modulation and emotion regulation. We integrate the data on major brain dynamics in stress neuroactivity that can be associated with childhood psychopathology to help inform future studies that are focused on the treatment and prevention of psychiatric disorders and learning problems in bullied children and adolescents.

Abstract
OBJECTIVE Although research has identified interpersonal, intrapersonal, and achievement-related factors that precipitate suicide attempts (SAs), how these factors vary by race/ethnicity is unknown. We examined racial/ethnic differences in SA precipitants in a racially/ethnically diverse sample of young adults (YAs) with a SA history. METHOD Two-hundred twenty-nine young adults, ages 18-33 (87% women), reported their method of attempt, and 200 of those reported on their SA precipitants. The latter were coded by three independent judges (Data were collected March 2012-December 2016.). RESULTS SAs were most often precipitated by intrapersonal factors, followed by interpersonal factors. Logistic regressions revealed that Hispanic, Asian, and Biracial YAs had higher odds of reporting interpersonal precipitants compared to Black YAs. CONCLUSION Suicide prevention and intervention should address both interpersonal and intrapersonal factors that increase vulnerability to SA across racial/ethnic groups, although interventions with Black YAs might focus more on intrapersonal than on interpersonal factors.

Abstract
The role of personality as distal risk factor for suicidal thoughts and behavior is still unclear. This review aims to propose two conceptual models that explain the psychological plausibility of Type D personality as distal risk factor and contributor to the transition from general to suicide distress. To support this aim, we performed a systematic review of existing studies on the association between Type D personality and suicidal distress. A systematic search yielded eight studies that reported on Type D personality and suicidal distress. Type D personality was robustly associated with suicidal thoughts and behaviors, across populations and countries. Type D was related to the level/frequency of suicidal ideation in seven studies, and suicide attempt in two studies. Our first theoretical model identifies intra-psychic (depression, alcohol misuse, posttraumatic stress) and interpersonal (low belonging, social isolation, lack of support) vulnerabilities of individuals with Type D that may fuel the development of suicidal thoughts and behaviors. Type D by itself will not account for why people become suicidal, but our second theoretical model suggests that the avoidant-passive tendencies of Type D individuals may result in persistent problem-solving deficits, and, eventually, feelings of entrapment that may contribute to the desire to escape from pain. We conclude that empirical evidence supports the hypothesized link between Type D personality, and suicidal thoughts and behaviors. Our conceptual models - albeit often supported by indirect evidence - further substantiate the plausibility of this link, and offer concrete guidance for future studies. Primarily, more longitudinal research is necessary.

Abstract
Previous research indicates that cybervictimization can lead to adolescent Internet addiction; however, there is a gap in the knowledge about the mediating and moderating variables facilitating this relationship. This study examines the role of rejection sensitivity as a mediator in this relationship and the role of parent–adolescent communication as a moderator for this mediation effect among Chinese adolescents. Participants were 1006 adolescents (M = 13.16 years, SD = 0.67), who completed the questionnaires anonymously. The questionnaires assessed the four variables of interest. Descriptive statistics and structural equation modeling were used for data analysis. The results show that the positive association between cybervictimization and adolescent Internet addiction is mediated by rejection sensitivity. Moreover, this indirect effect is stronger for adolescents with low parent–adolescent communication than for those with high parent–adolescent communication.

Abstract
BACKGROUND Rejection sensitivity (RS) is a personality disposition characterized by oversensitivity to social rejection; individuals who are sensitive to social rejection tend to anxiously or angrily expect, readily perceive, and overreact to it. The associations between (a) RS and aggression and (b) RS and victimization have been studied in recent years. However, the strength of these associations varied considerably between studies. This review aimed to synthesize the primary literature to improve our insight into these associations. METHOD A comprehensive literature search yielded 52 studies (with a total of 66,405 participants and producing 203 effect sizes) on the RS-aggression and RS-victimization associations. Three-level meta-analytic models were used to synthesize effect sizes and to examine potential moderators of the RS-aggression association and the RS-victimization association, respectively. RESULTS There was a small but significant association between RS and aggression (pooled r = .183; p < .001) and a slightly below moderate and significant association between RS and victimization (pooled r = .298; p < .001). The RS-aggression association was stronger for angry RS than for anxious RS and stronger for reactive aggression than for proactive aggression. Similar results were obtained in analyzing the longitudinal associations only. CONCLUSIONS RS is significantly associated with aggression and victimization. The implications of the results for clinical practice as well as directions for future research are discussed.

Abstract
Self-injurious thoughts and behaviors (SITBs) are significant public health problems in adolescence. The current article provides a comprehensive systematic review examining the relationship between events leading to perceived low relational evaluation (e.g. social rejection) and SITBs among adolescents. Theoretical work posits that low relational evaluation is experienced as psychologically painful, a known correlate of SITBs. Therefore, events leading to low relational evaluation may be particularly informative in understanding the context of SITBs. The current review examines how experiences of low relational evaluation that are hypothesized to elicit psychological pain, such as social rejection, low popularity, and peer victimization are related to engagement in SITBs in adolescence. A total of 56 articles meeting inclusion criteria were identified. The hypothesis of an association between indicators of low relational evaluation and SITBs was generally supported throughout the literature, with more consistency found among studies examining suicidal ideation specifically. However, interpretation of the findings is constrained by various methodological limitations of studies. The present review concludes with a theoretical conceptualization of the relationship between perceived relational value and SITBs, leveraging social and evolutionary psychological theory, to guide future research into this topic.

Abstract
Suicide is a major public health concern accounting for 800 000 deaths globally each year. Although there have been many advances in understanding suicide risk in recent decades, our ability to predict suicide is no better now than it was 50 years ago. There are many potential explanations for this lack of progress, but the absence, until recently, of comprehensive theoretical models that predict the emergence of suicidal ideation distinct from the transition between suicidal ideation and suicide attempts/suicide is key to this lack of progress. The current article presents the integrated motivational-volitional (IMV) model of suicidal behaviour, one such theoretical model. We propose that defeat and entrapment drive the emergence of suicidal ideation and that a group of factors, entitled volitional moderators (VMs), govern the transition from suicidal ideation to suicidal behaviour. According to the IMV model, VMs include access to the means of suicide, exposure to suicidal behaviour, capability for suicide (fearlessness about death and increased physical pain tolerance), planning, impulsivity, mental imagery and past suicidal behaviour. In this article, we describe the theoretical origins of the IMV model, the key premises underpinning the model, empirical tests of the model and future research directions.This article is part of the theme issue 'Evolutionary thanatology: impacts of the dead on the living in humans and other animals'.
