Cybervictimization in adolescence and its association with subsequent suicidal ideation/attempt beyond face-to-face victimization: a longitudinal population-based study

Association of screen-based activities and risk of self-harm and suicidal behaviors among young people: A systematic review and meta-analysis of longitudinal studies

Emerging evidence suggests that screen-based activities are associated with self-harm and suicidal behaviors. This study aimed to examine these associations among young people through a meta-analysis. We systematically searched EBSCO pshyARTICLES, MEDLINE (via PubMed), EMBASE, and Web of Science from their inception to April 1, 2022, and updated on May 1, 2024. Longitudinal studies reporting the association between various screen-based activities and subsequent self-harm and suicidal behaviors in young people aged 10 to 24 were included. Nineteen longitudinal studies were included in the qualitative synthesis, and 13 studies comprising 43,489 young people were included in the meta-analysis, revealing that total screen use is significantly associated with the risks of self-harm and suicidal behaviors. Cyberbullying victimization was also related to these adverse outcomes. Subgroup analyses indicated that social media use and problematic screen use are significant risk factors for self-harm and suicidal behaviors. Study quality was appraised using the Newcastle-Ottawa Scale, and potential publication bias was deemed unlikely to affect the results significantly. These findings suggest that screen-based activities should be considered in the management and intervention strategies for self-harm and suicidal behaviors in young people.

Cyberbullying Perpetration and Victimization as Risk Factors for Self-Harm: Results From a Longitudinal Cohort Study of 13-14-Year-Olds in England

PURPOSE

Cyberbullying is a crucial issue that affects adolescent mental health, with evidence to suggest that adolescents who are victims of cyberbullying are at higher risk for self-harm. However, longitudinal evidence is lacking, meaning the direction of effects cannot be established. This study investigated longitudinal associations between levels of cyberbullying involvement (bully, victim, or both), frequency, and self-harm a year later in an adolescent sample.

METHODS

Data were collected from Year 9 students (13-14-year-olds; N = 1,195) enrolled in 19 schools in Southwest England using an online questionnaire with a 1-year follow-up period (October 2019-October 2020). Multivariable logistic regression analysis was conducted to test for associations between different levels of cyberbullying involvement at baseline and the likelihood of self-harm a year later, adjusting for key covariates. A secondary regression analysis also explored the associations between the frequency of cyberbullying involvement at baseline and subsequent self-harm.

RESULTS

Compared to those with no cyberbullying involvement, individuals who were both victims and perpetrators (adjusted odds ratio = 2.94, 95% confidence interval: 1.99-4.34) as well as victims only (adjusted odds ratio = 2.81, 95% confidence interval: 1.95-4.04) showed an increased risk of subsequent self-harm. In terms of frequency, associations were found between frequent and occasional cyberbullying and self-harm for both victims and perpetrators; however, associations for the perpetrator group attenuated to the null following adjustment for covariates.

DISCUSSION

Our findings highlight cyberbullying in early adolescence as a risk factor for subsequent self-harm. Cyberbullying prevention should be a priority for school mental health interventions, with consideration that most perpetrators of cyberbullying may also be victims.

The effect of bullying and cyberbullying on predicting suicide risk in adolescent females: The mediating role of depression

This paper analyzed the role of depression as a mediator in the association between bullying, cyberbullying, and suicide risk in adolescent females. A total of 751 Colombian adolescent females (M= 13.71, SD=1.897), who were administered the Plutchik Suicide Risk Scale, the Beck Depression Inventory, the European Bullying Intervention Project Questionnaire and Cyberbullying. Bullying victimization and aggression and cyberbullying victimization were found to contribute statistically significant effects that explaining 22 % of the variance in depression. The variables of victimization in bullying and cyberbullying and depression explained 64 % of the variance in suicidal risk, and depression mediated the association between victim and aggressor roles in bullying and cyberbullying in predicting suicidal risk, whose total direct and indirect effects are statistically significant. The findings support the role of depression as a mediating variable between bullying and cyberbullying and suicidal risk in female adolescents and highlight the importance of focusing prevention and intervention efforts on risk factors for depression and suicidal behavior in cases of bullying and cyberbullying.

Perception of social inclusion/exclusion and response inhibition in adolescents with past suicide attempt: a multidomain task-based fMRI study

The occurrence of suicidal behaviors increases during adolescence. Hypersensitivity to negative social signals and deficits in cognitive control are putative mechanisms of suicidal behaviors, which necessitate confirmation in youths. Multidomain functional neuroimaging could enhance the identification of patients at suicidal risk beyond standard clinical measures. Three groups of adolescents (N = 96; 78% females, age = 11.6-18.1) were included: patients with depressive disorders and previous suicide attempts (SA, n = 29); patient controls with depressive disorders but without any suicide attempt history (PC, n = 35); and healthy controls (HC, n = 32). We scanned participants with 3T-MRI during social inclusion/exclusion (Cyberball Game) and response inhibition (Go-NoGo) tasks. Neural activation was indexed by the blood-oxygenation-level dependent (BOLD) of the hemodynamic response during three conditions in the Cyberball Game ("Control condition", "Social Inclusion", and "Social Exclusion"), and two conditions in Go-NoGo task ("Go" and "NoGo" blocks). ANCOVA-style analysis identified group effects across three whole-brain contrasts: 1) NoGo vs. Go, 2) Social inclusion vs. control condition, 3) Social exclusion vs. control condition. We found that SA had lower activation in the left insula during social inclusion vs. control condition compared to PC and HC. Moreover, SA compared to PC had higher activity in the right middle prefrontal gyrus during social exclusion vs. control condition, and in bilateral precentral gyri during NoGo vs. Go conditions. Task-related behavioral and self-report measures (Self-reported emotional reactivity in the Cyberball Game, response times and number of errors in the Go-NoGo Task) did not discriminate groups. In conclusion, adolescent suicidal behaviors are likely associated with neural alterations related to the processing of social perception and response inhibition. Further research, involving prospective designs and diverse cohorts of patients, is necessary to explore the potential of neuroimaging as a tool in understanding the emergence and progression of suicidal behaviors.

The relationship between cyberbullying perpetration/victimization and suicidal ideation in healthy young adults: the indirect effects of positive and negative psychotic experiences

BACKGROUND

Even though not all cyber bullies or victims think of (or consider) suicide, they clearly appear to be at an increased risk. One possible strategy to reduce suicide risk is to decrease cyberbullying occurrence; but this approach has its limitations, as it is certainly an illusion to believe that cyberbullying could be controlled or eliminated in a digitalized world. Another alternative and interesting strategy is to consider mediating factors that may indirectly affect suicidality. To this end, our purpose was to test the hypothesis that positive and negative psychotic experiences (PEs) mediate the relationship from cyberbullying perpetration/victimization to suicidal ideation (SI).

METHOD

The study followed a cross-sectional design, and was conducted during the period from June to September 2022. A total of 3103 healthy community participants from Lebanon were included (mean age 21.73 ± 3.80 years, 63.6% females).

RESULTS

After adjusting over potential confounders, mediation analysis models showed that both positive and negative PEs partially mediated the associations between cyberbullying victimization/perpetration and SI. Higher cyberbullying perpetration and victimization were significantly associated with greater positive and negative PEs; more severe positive and negative PEs were significantly associated with higher levels of SI. Higher cyberbullying victimization and perpetration were significantly and directly associated with higher levels of SI.

CONCLUSION

In light of our preliminary findings, there appears to be an urgent need for a new focus on carefully assessing and addressing attenuated psychotic symptoms in healthy individuals engaged in cyberbullying either as victims or bullies and who present with SI. It is important that school counselors and decision-makers consider a holistic approach taking into account both external/environmental (bullying) and internal/individual (PEs) factors in their suicide prevention programs. Future longitudinal research in larger samples are still required to confirm our findings and further elucidate the mechanisms underlying the relationship between cyberbullying and suicide.

Predicting Participation Willingness in Ecological Momentary Assessment of General Population Health and Behavior: Machine Learning Study

BACKGROUND

Ecological momentary assessment (EMA) is widely used in health research to capture individuals' experiences in the flow of daily life. The majority of EMA studies, however, rely on nonprobability sampling approaches, leaving open the possibility of nonrandom participation concerning the individual characteristics of interest in EMA research. Knowledge of the factors that predict participation in EMA research is required to evaluate this possibility and can also inform optimal recruitment strategies.

OBJECTIVE

This study aimed to examine the extent to which being willing to participate in EMA research is related to respondent characteristics and to identify the most critical predictors of participation.

METHODS

We leveraged the availability of comprehensive data on a general young adult population pool of potential EMA participants and used and compared logistic regression, classification and regression trees, and random forest approaches to evaluate respondents' characteristic predictors of willingness to participate in the Decades-to-Minutes EMA study.

RESULTS

In unadjusted logistic regression models, gender, migration background, anxiety, attention deficit hyperactivity disorder symptoms, stress, and prosociality were significant predictors of participation willingness; in logistic regression models, mutually adjusting for all predictors, migration background, tobacco use, and social exclusion were significant predictors. Tree-based approaches also identified migration status, tobacco use, and prosociality as prominent predictors. However, overall, willingness to participate in the Decades-to-Minutes EMA study was only weakly predictable from respondent characteristics. Cross-validation areas under the curve for the best models were only in the range of 0.56 to 0.57.

CONCLUSIONS

Results suggest that migration background is the single most promising target for improving EMA participation and sample representativeness; however, more research is needed to improve prediction of participation in EMA studies in health.

Trajectories of Screen Time across Adolescence and Their Associations with Adulthood Mental Health and Behavioral Outcomes

Excessive screen time among adolescents is discussed as a significant public health concern. Identifying adolescent longitudinal patterns of time spent on regularly-used media screens and understanding their young adulthood mental health and behavioral issue correlates may help inform strategies for improving these outcomes. This study aimed to characterize joint developmental patterns of time spent on videogames, surfing/chatting the Internet, and TV/DVDs during adolescence (at ages 11, 13, 15, 17) and their associations with mental health (i.e., depression, anxiety, suicidal ideation, and self-injury) and behavioral issues (i.e., substance use, delinquency, aggression) in early adulthood (at age 20). A parallel-process latent class growth analysis was used to model data from a diverse community-ascertained sample of youth in Zurich, Switzerland (n = 1521; 51.7% males). Results suggested that a five-class model best fitted the data: (1) low-screen use, 37.6%; (2) increasing chatting/surfing, 24.0%; (3) moderate-screen use, 18.6%; (4) early-adolescence screen use, 9.9%; and (5) increasing videogame and chatting/surfing, 9.9%. After adjusting for baseline levels of outcomes (primarily at age 11), the trajectory groups differed in their associations with adulthood outcomes of mental health and behavioral problems, indicating the importance of problematic screen usage patterns in predicting these outcomes. Future research to test the directionality of these associations will be important. These findings suggest which patterns of screen use may be a marker for later mental health and behavioral issues in different domains.

Association of childhood bullying victimisation with suicide deaths: findings from a 50-year nationwide cohort study

BACKGROUND

Bullying victimisation has been associated with increased risk of suicide ideation and attempt throughout the lifespan, but no study has yet examined whether it translates to a greater risk of death by suicide. We aimed to determine the association of bullying victimisation with suicide mortality.

METHODS

Participants were drawn from the 1958 British birth cohort, a prospective follow-up of all births in 1 week in Britain in 1958. We conducted logistic regressions on 14 946 participants whose mothers reported bullying victimisation at 7 and 11 years with linked information on suicide deaths through the National Health Service Central Register.

RESULTS

Fifty-five participants (48 males) had died by suicide between the age 18 and 52 years. Bullying victimisation was associated with suicide mortality; a one standard deviation increases in bullying victimisation linked to an increased odds for suicide mortality [odds ratio (OR) 1.29; 1.02-1.64] during adulthood. The OR attenuated by 11% after adjustment for individual (e.g. behavioural and emotional problems) and familial characteristics (e.g. adverse childhood experiences, 1.18; 0.92-1.51). Analysis of bullying victimisation frequency categories yields similar results: compared with individuals who had not been bullied, those who had been frequently bullied had an increased odds for suicide mortality (OR 1.89; 0.99-3.62).

CONCLUSION

Our study suggests that individuals who have been frequently bullied have a small increased risk of dying by suicide, when no other risk factors is considered. Suicide prevention might start in childhood, with bullying included in a range of inter-correlated vulnerabilities encompassing behavioural and emotional difficulties and adverse experiences within the family.

The Bridge between Cybervictimization and Suicidal Ideation among Adolescents: A Vicious Cycle of Hopelessness

Cybervictimization has been shown to relate to suicidal ideation. However, few studies have fully clarified the directionality of this relationship, and little is known about the potential mediating and moderating mechanisms of this relationship. To address these gaps, the current study tested bidirectional relationships among cybervictimization, hopelessness, and suicidal ideation across three years using a cross-lagged design and examined whether these relationships varied by openness, family socioeconomic status, perceived economic stress, and sex. A total of 2,407 Chinese adolescents (50.23% female, M_age = 12.75, SD = 0.58 at baseline) from seven schools participated in the present study. The results indicated that cybervictimization was related to hopelessness and suicidal ideation. There was a vicious cycle between cybervictimization and hopelessness after controlling the effects of cyberbullying at T1. There were significant reciprocal relationships between hopelessness and suicidal ideation. Hopelessness at T2 mediated the relationship between cybervictimization at T1 and suicidal ideation at T3. Openness moderated the relationships among cybervictimization, hopelessness, and suicidal ideation. Family socioeconomic status, perceived economic stress, and sex did not play a moderating role. These findings will help to understand that intervening with hopelessness is a promising way to reduce adolescents' cybervictimization and suicidal ideation, and promoting adolescents' openness is an effective approach to alleviate the negative outcome of cybervictimization.

Longitudinal associations between cyber victimization and problematic mobile phone use in adolescents: Disentangling between-person effects from within-person effects

BACKGROUND

Being the target of cyber victimization has been shown to be connected with several forms of maladjustment among adolescents. However, there is not a clear understanding of the impact of cyber victimization on Problematic Mobile Phone Use (PMPU) and the potential mechanism underlying the association. The present study tested the longitudinal association between cyber victimization and adolescents' PMPU as well as the mediating role of sleep problems in this association.

METHODS

A sample of 1835 Chinese adolescents (55.9 % boys; M_age = 12.34) completed self-report questionnaires regarding cyber victimization, sleep problems and PMPU at four time points, using 6-month intervals. Gender, age and socioeconomic status were controlled for in the analyses. We tested cross-lagged panel models (CLPMs) and random intercept cross-lagged panel models (RI-CLPMs) to separate between- and within-person effects, allowing a robust and rigorous test of relationships among variables.

RESULTS

As hypothesized, at the within-person level, cyber victimization was a predictive risk factor of later PMPU among adolescents, and sleep problems served as an explanatory mechanism by which cyber victimization predicted adolescents' PMPU over time.

CONCLUSION

These findings contribute to identifying adolescents at risk for engaging in PMPU, as well as the prevention and intervention.

The longitudinal course of childhood bullying victimization and associations with self-injurious thoughts and behaviors in children and young people: A systematic review of the literature

INTRODUCTION

Bullying victimization has consistently been highlighted as a risk factor for self-injurious thoughts and behaviors (SITBs) in young people. This systematic review of prospective, community-based studies explored associations between bullying victimization (traditional/face-to-face and cyber) across the full spectrum of self-harm and suicidality, in children and young people aged up to (and including) 25 years. Importantly, associations by sex/gender were explored.

METHODS

MEDLINE, Embase, PsycINFO, CINAHL and Scopus were searched for articles meeting the inclusion criteria. Articles were screened by title, abstract and full text. Quality appraisal was performed using the Newcastle-Ottawa Scale for cohort studies. Data were synthesized narratively. The protocol is registered on PROSPERO (CRD42021261916) and followed PRISMA 2020 guidelines.

RESULTS

A total of 35 papers were included, across 17 countries. Results were presented by bullying type: traditional/face-to-face (n = 25), cyber (n = 7) and/or an aggregate of both types (n = 7). Outcomes included suicidal ideation (n = 17), self-harm (n = 10), suicide attempt (n = 4), NSSI (n = 4), other (n = 7). Studies measured outcomes in under 18s (n = 24), 18-25-year-olds (n = 8) and both under 18s and 18-25-year-olds (n = 3). Studies exploring the role of sex/gender (20%) found some interesting nuances.

CONCLUSIONS

Some weak to strong associations between bullying and SITBs were found yet conclusions are tentative due to study heterogeneity (e.g., methods used, conceptualizations and operationalisations of exposures/outcomes). Future research should address methodological issues raised in this review, and further explore gender differences in bullying, including by bullying sub-types (e.g., overt or relational) and victim status (e.g., victim or bully-victim).

Does Religion Buffer Against the Detrimental Effect of Cyberbullying Victimization on Adults' Health and Well-Being? Evidence from the 2014 Canadian General Social Survey

While prior research has well-documented the detrimental effect of cyberbullying victimization on health and well-being among children and adolescents, less is known about whether the same adverse pattern can be observed among adults. Moreover, it is unclear about what psychosocial resources might moderate this association. The present study uses a nationally representative cross-sectional survey-2014 Canadian General Social Survey (N = 17,548)-to examine three research questions. First, is cyberbullying victimization associated with adults' self-rated health, mental health, and life satisfaction? Second, how does religiosity-religious service attendance and religious beliefs-moderate this association? Third, do any observed patterns further differ for men and women? Through a series of logistic and ordinary least squares regression models, the results show that adults who experienced cyberbullying victimization in the past 5 years are more likely to report poor self-rated health and mental health compared to those who did not experience cyberbullying victimization in the past 5 years. Likewise, cyberbullying victimization is also associated with lower levels of life satisfaction. In addition, the adverse associations of cyberbullying victimization in the past 5 years with self-rated health and life satisfaction are weaker among those who attended religious service at least once a week in the past twelve months. A similar pattern is observed for the buffering effect of viewing religious beliefs as very important in the adverse association of cyberbullying victimization in the past 5 years with self-rated life satisfaction. There is also evidence suggesting the gendered buffering effect of the importance of religious beliefs in the association between cyberbullying victimization and self-rated health. This study makes important empirical and theoretical contributions to the growing field of research on the association between cyberbullying victimization and health and well-being and to our understanding of how religion matters to individuals dealing with stressful experiences.

Assessing Cyberbullying in Adolescence: New Evidence for the Spanish Version of the European Cyberbullying Intervention Project Questionnaire (ECIP-Q)

The prevention of cyberbullying at school requires assessing its prevalence by means of brief measurement instruments with adequate psychometric properties. The present study aims to study the psychometric properties of the European Cyberbullying Intervention Project Questionnaire (ECIP-Q) in a sample of 1777 Spanish adolescents (54.1% women, M = 15.71 years; SD = 1.26), selected by stratified random cluster sampling. The two-factor model (victimization and aggression) displayed appropriate goodness of-fit indices. Configural measurement invariance model across gender was found. The omega reliability coefficient for the victimization subscale was 0.82, and for the aggression subscale was 0.68. The ECIP-Q scores were negatively associated with self-esteem and prosocial behavior, and positively associated with depression symptoms and emotional and behavioral difficulties. Significant differences were found between victim and non-victim groups, and between aggressor and non-aggressor groups on the same variables. Victims and aggressors scored lower on self-esteem, and higher on depression symptoms and emotional and behavioral difficulties than those not involved in cyberbullying situations. These findings contribute to demonstrate the satisfactory psychometric quality of the ECIP-Q scores as an assessment tool for cyberbullying in Spanish adolescents.

Investigating the relationship between bullying involvement and self-harmful thoughts and behaviour in young people: A systematic review

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.

The Impact of Bullying Victimization and Sexual Orientation on the Severity of Suicidal Behavior

Background: Lesbian, gay, and bisexual youth face a disproportionate risk of suicidal ideation and attempt compared to heterosexual counterparts. Escalation from ideation to attempt can occur quickly, and youth who survive suicide attempts are likely to pursue subsequent, riskier attempts. This study examines the effects of bullying and sexual orientation on suicidal outcomes. Methods: Data came from the national, school-administered 2017 Youth Risk Behavior Survey (N = 14,765). Bivariate associations, binomial logistic regressions, and ordinal logistic regressions were performed. Results: Lesbian/gay, bisexual, and unsure youth reported greater odds of ideation and attempts compared to heterosexual youth. For ideation, increased effects were inconsistent across bullying types and significant interactions were found for bisexual youth who were bullied in school, and for lesbian/gay youth who were cyberbullied. Conclusion: These results underscore the need to understand bullying victimization for lesbian, gay, and bisexual youth. Awareness of increasing cyberbullying and creating school environments of no-bullying tolerance in the post-pandemic era are among the challenges ahead.

Bullying perpetration and victimization associations to suicide behavior: a longitudinal study

Previous studies have reported a longitudinal association between cybervictimization and suicidal thoughts and behavior. However, the relationship between cyber-perpetration and prospective suicide risk remains unclear. The sample was composed of 2150 at-risk adolescents (mean age 15.42), enrolled in Vocational Education and Training high schools in Israel. Cyberbullying, traditional bullying, depression, hostility, serious suicidal ideations, and suicide attempts were assessed through self-report questionnaires at the beginning of the school year and one year later. All types of victimization and preparation were cross-sectionally associated with suicide ideation and attempts. Longitudinal associations were found between cyber-perpetration and suicidal ideation/attempts. Cyber-perpetrators were found to be over twice more likely to report serious suicidal ideation (OR = 2.04) or attempt suicide (OR = 2.64) in the subsequent year compared to noninvolved adolescents. These associations were significant even after adjusting for baseline depression, hostility, and traditional bullying. Traditional bullying perpetration was prospectively associated with suicide attempts. Traditional victimization was cross-sectionally associated with suicide ideation and attempts but not prospectively. Cybervictimization was prospectively associated with suicide ideation but not to suicide attempts. The findings demonstrate the prospective risk of involvement in bullying in regard to suicide ideation and behavior. Cyberbullying was found to be a somewhat differentiated phenomena from traditional bullying.

Correlational study on cyberbullying and social abilities in intercultural teenagers

This article analyzes the relationship between cyberbullying profile by racist reasons and social abilities in a group of intercultural teenagers living in Spain (N = 1478). The study includes participants aged between 12 and 16 years old (M = 13.99; SD = 1.352). Of these, 738 were male (49.9%) and 740 were female (50.1%). A correlational study was carried out using online tools with suitable psychometrics parameters (content-construct validity and reliability). The first one was a scale that measured social abilities, and the second one evaluated racist or xenophobic cyberbullying, differentiating the victim and aggressor profiles. The results indicated five main findings: (1) generally, the participants analyzed present all their social abilities; (2) for the most part, these participants do not normally experience cyberbullying; (3) a positive correlation exists between the majority of social abilities analyzed and the cybervictim profile. It was also observed a negative correlation between the social ability associated with the ability of making requests and this profile; (4) there is a positive correlation among the six social abilities analyzed and the cyberaggressor profile; (5) the racist or xenophobic cyberbullying are driven not only by the absence of social abilities, but in some cases, they are also driven by socio-demographic variables (i.e., age and gender). Likewise, this work shows how the absence of some social abilities in some participants involve racist or xenophobic experiences as victims and as aggressors, which may be of interest for the analysis of teenagers’ behavior in intercultural contexts, as well as according to age and gender. More transcultural research need to be carried out to know the global perspective of the link between social abilities and the different profiles of racist and xenophobic cyberbullying, framed in the context of social psychology and studies of mass communication.

Developmental associations between bullying victimization and suicidal ideation and direct self-injurious behavior in adolescence and emerging adulthood

BACKGROUND

Bullying, suicide, and self-injury are significant issues among young people. Extensive research has documented bullying victimization associations with suicidal ideation and self-injury; however, the modeling approaches used have mostly not addressed the relations between these constructs at the within-person level, and it is these links that are critical for testing developmental theories and guiding intervention efforts. This examined the within-person, bidirectional relations between these constructs in adolescence and emerging adulthood.

METHODS

Participants were from the Zurich Project on Social Development from Childhood to Adulthood (z-proso). Random intercept cross-lagged panel models (RI-CLPMs) were fit to general and sexual bullying victimization and suicidal ideation data at ages 15, 17, and 20 (n = 1465), and general and sexual victimization and direct self-injurious behavior data at ages 13, 15, 17, and 20 (n = 1482).

RESULTS

There was a positive within-person effect of age 15 general bullying victimization on age 17 suicidal ideation (β = .10) and age 17 suicidal ideation on age 20 general bullying victimization (β = .14).

CONCLUSIONS

General bullying victimization and suicidal ideation may have detrimental effects on each other over development but at different stages.

The Predictability of Routine Activity Theory for Cyberbullying Victimization Among Children and Youth: Risk and Protective Factors

Cyberbullying has been pervading worldwide with negative implications for victims. Therefore, there is an urgent need to better understand this phenomenon and the factors that predict it, as the basis for effective prevention and intervention efforts. The current research aims to examine routine activity theory (RAT) as a theoretical framework predictive of cyberbullying victimization (CV) among children and youth. It was hypothesized that each of the RAT measures and the convergence of all measures predict CV. Data were collected from 5,719 primary, middle, and high school Israeli students (51.9% females) during the 2019-2020 school year via online questionnaires. Regression and moderation analyses were conducted to assess the predictability of CV from RAT measures, separately and converged. All RAT measures, separately and converged, predict CV. While off-line trust negatively predicts CV, other control variables, that is, online trust, educational institution phase, and gender, do not. Implications for school programs and guidelines for parents address the risk and protective factors of CV found. This study provides support for the predictability of CV from RAT and expands the knowledge of risk and protective factors predictive of CV.

Association of Cyberbullying Experiences and Perpetration With Suicidality in Early Adolescence

IMPORTANCE

Adolescent suicidality (ie, suicidal ideation or attempts) is a major public health concern. Cyberbullying experiences and perpetration have become increasingly prevalent and are associated with mental health burden, but their roles as independent suicidality risk factors remain unclear. Data are needed to clarify their contribution to teen suicidality to inform suicide prevention efforts.

OBJECTIVE

To examine whether cyberbullying experiences and perpetration are distinct stressors divergent from other forms of peer aggression experiences in their association with suicidality in early adolescence.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional analysis used data collected between July 2018 and January 2021 from the Adolescent Brain Cognitive Development (ABCD) study, a large, diverse sample of US children aged 10 to 13 years.

EXPOSURES

Youth reports of cyberbullying experiences or perpetration.

MAIN OUTCOMES AND MEASURES

The main outcome was youth-reported suicidality (past or present, as reported in the ABCD 2-year follow-up assessment). Covariates included demographics, established environmental risk and protective factors for youth suicidality, psychopathology, and experiences or perpetration of offline peer aggression.

RESULTS

A total of 10 414 ABCD participants were included in this study. Participants had a mean (SD) age of 12.0 (0.7) years and 4962 (47.6%) were female; 796 (7.6%) endorsed suicidality. A total of 930 (8.9%) reported experiencing cyberbullying and 96 (0.9%) reported perpetrating cyberbullying. Of the perpetrators, 66 (69.0%) also endorsed experiencing cyberbullying. Controlling for demographics, experiencing cyberbullying was associated with suicidality (odds ratio [OR], 4.2 [95% CI, 3.5-5.1]; P < .001), whereas perpetrating cyberbullying was not (OR, 1.3 [95% CI, 0.8-2.3]; P = .30). Experiencing cyberbullying remained associated with suicidality when accounting for negative life events, family conflict, parental monitoring, school environment, and racial and ethnic discrimination (OR, 2.5 [95% CI, 2.0-3.0]; P < .001) and when further covarying for internalizing and externalizing psychopathology (OR, 1.8 [95% CI, 1.4-2.4]; P < .001). Both being a target and being a perpetrator of offline peer aggression were associated with suicidality (OR, 1.5 [95% CI, 1.1-2.0] for both), controlling for all covariates described earlier. Cyberbullying experiences remained associated with suicidality (OR, 1.7 [95% CI, 1.3-2.2]; P < .001, controlling for all covariates) when included with offline peer aggression experiences and perpetration.

CONCLUSIONS AND RELEVANCE

In this cross-sectional study, experiencing-but not perpetrating-cyberbullying was associated with suicidality in early adolescence. This association was significant over and above other suicidality risk factors, including offline peer aggression experiences or perpetration. These findings can inform adolescent suicide prevention strategies, and they suggest that clinicians and educational staff working with this population should routinely evaluate for adolescents' experience with cyberbullying.

Systematic review of risk and protective factors for suicidal and self-harm behaviors among children and adolescents involved with cyberbullying

Cyberbullying is associated with increased risk of suicidal and self-harm behaviors in children and adolescents. However, no review to date has explored factors that exacerbate and mitigate this relationship. This systematic review concerns research on factors that influence the impact of cyberbullying on suicidal and self-harm behaviors. Four bibliographic databases were explored and references in included articles were searched. We identified 727 articles and retained 66 that met inclusion criteria. Research has identified multiple risk factors which have been associated with increased suicide risk in general (mental health problems, substance abuse, loneliness, stress, sexual orientation/gender identity issues and violent behaviors). Others risk factors more specific to cyberbullying were: Autism Spectrum Disorder, Intellectual and Developmental Disorders, obesity, having asthma and severity of cyberbullying. Fewer studies concern protective factors. School connectedness, restrictive style of parenting, parental support, life satisfaction, having a healthy diet, personal skills and having family dinners were associated with less risk of suicidal and self-harm behaviors following cyberbullying. These protective factors suggest prevention strategies to reduce the impacts of cyberbullying by teaching better personal skills, promoting school social connections and proposing family interventions. More research is needed including exploration of the differential impacts of different forms of cyberbullying, and evaluations of the impacts of programs to increase personal skills, improve family relationships and foster school connectedness to reducing suicidal and self-harm behaviors in this vulnerable population.

Cyber-victimisation and mental health in young people: a co-twin control study

BACKGROUND

The rise of social media use in young people has sparked concern about the impact of cyber-victimisation on mental health. Although cyber-victimisation is associated with mental health problems, it is not known whether such associations reflect genetic and environmental confounding.

METHODS

We used the co-twin control design to test the direct association between cyber-victimisation and multiple domains of mental health in young people. Participants were 7708 twins drawn from the Twins Early Development Study, a UK-based population cohort followed from birth to age 22.

RESULTS

Monozygotic twins exposed to greater levels of cyber-victimisation had more symptoms of internalising, externalising and psychotic disorders than their less victimised co-twins at age 22, even after accounting for face-to-face peer victimisation and prior mental health. However, effect sizes from the most stringent monozygotic co-twin control analyses were decreased by two thirds from associations at the individual level [pooled β across all mental health problems = 0.06 (95% CI 0.03-0.10) v. 0.17 (95% CI 0.15-0.19) in individual-level analyses].

CONCLUSIONS

Cyber-victimisation has a small direct association with multiple mental health problems in young people. However, a large part of the association between cyber-victimisation and mental health is due to pre-existing genetic and environmental vulnerabilities and co-occurring face-to-face victimisation. Therefore, preventative interventions should target cyber-victimisation in conjunction with pre-existing mental health vulnerabilities and other forms of victimisation.

Applications mobiles pour soutenir la santé mentale des jeunes : opportunités et défis

Introduction L’adolescence est une période sensible pendant laquelle plusieurs changements ont le potentiel d’affecter le développement cognitif et psychosocial de l’individu. C’est aussi au cours de cette période que l’on note la plus forte augmentation des troubles de santé mentale. Plusieurs initiatives cherchent à prévenir l’émergence ou la détérioration de ces troubles auprès de jeunes en situation de vulnérabilité parce que vivant des difficultés émotionnelles ou du comportement, ou bien en raison d’expériences adverses auxquelles ils sont (ou ont été) confrontés. À ces efforts, le recours à la technologie est habituellement perçu comme naturel, voire souhaitable, auprès de ces « natifs du numérique ».

Objectif Cette recension critique propose d’examiner les avantages et inconvénients documentés dans la littérature et rencontrés dans le cadre du développement d’une application mobile (app) afin d’évaluer leur potentiel à soutenir la santé mentale et la résilience des jeunes en contextes d’adversité et les facteurs susceptibles d’amoindrir ces impacts.

Résultats/Constats Les apps, par leur format et mode d’utilisation, permettent de transmettre aux jeunes une information juste et fondée sur les meilleures connaissances tout en étant arrimée à leur réalité. Les apps représentent aussi une opportunité d’engager certains jeunes dans un processus de changement ou de les soutenir dans une éventuelle demande d’aide. Bien qu’elles soient disponibles en tout temps et qu’elles peuvent respecter leurs besoins d’autonomie et de confidentialité, de nombreux défis demeurent afin qu’elles puissent soutenir la santé mentale des jeunes, incluant le peu d’attention accordée à la validation scientifique, la protection des données personnelles et la capacité de rétention et d’engagement des jeunes.

Conclusion. Cette analyse critique des connaissances propose une réflexion qui pourrait s’avérer utile afin de soutenir le développement de futures apps rencontrant les meilleurs standards auprès d’une multitude d’acteurs susceptibles de les créer et de les utiliser.

+Fièr : une application mobile pour aider les jeunes issus de la communauté LGBTQ+ et leur famille

Les personnes LGBTQ+ sont 1,5 à 4 fois plus à risque que les personnes hétérosexuelles de souffrir de troubles de santé mentale (p. ex. dépression, anxiété, comportements suicidaires).

Objectif L’objectif est de décrire le processus de développement d’une application mobile pour les jeunes LGBTQ+ et leur famille. L’article fait partie d’un programme de recherche ayant comme but général de doter les jeunes LGBTQ+ et leur famille d’outils technologiques leur permettant de développer et soutenir des stratégies d’adaptation face à la stigmatisation. En effet, ceux-ci sont confrontés à des stresseurs uniques, à la fois dans la sphère publique (p. ex. victimisation) et personnelle (p. ex. développement identitaire et le processus de coming out).

Méthode Nous adapterons l’application mobile +Fort © développée par l’équipe dirigée par de la docteure Isabelle Ouellet-Morin, conçue pour soutenir les jeunes vivant de l’intimidation à réduire ces expériences, et nous créerons +Fièr/+ Proud, qui fera l’objet d’un codesign et d’une étude pilote auprès de participants LGBTQ+ âgés de 13 à 25 ans.

Retombées À terme, notre espoir est que les jeunes LGBTQ+, à l’échelle nationale et internationale, puissent explorer et développer des stratégies d’adaptation soutenant leur mieux-être, apprendre à l’aide d’outils personnalisés, partager leurs expériences uniques et informer leurs proches des défis auxquels ils font face et se battent en silence.

Trajectories of suicide attempts from early adolescence to emerging adulthood: prospective 11-year follow-up of a Canadian cohort

BACKGROUND

Suicide is a leading cause of mortality in youth, yet the course of suicide attempts is poorly documented. We explored the vulnerable transition from adolescence to emerging adulthood to identify group trajectories and risk factors.

METHODS

The National Longitudinal Survey of Children and Youth is a prospective representative cohort of Canadian children. We followed participants aged 7-11 years in 1994-95 to age 23 (2008-09). We modelled self-reported past-year suicide attempts (ages 12 to 23 years) using growth mixture models. We analysed risk factors from self- and parent-report questionnaires at pre-adolescence (ages 10-11) and early adolescence (ages 12-13) using multinomial logistic regressions. Analyses were adjusted for sample non-response and attrition.

RESULTS

In 2233 participants answering questions on teen and adult suicide attempts, we identified three trajectories: never attempted (96.0%), adolescence-limited (2.0%) and persisting into adulthood (2.0%). Adolescent girls aged 12-13 with depression/anxiety symptoms, and with mothers experiencing depression had higher risks of adolescence-limited than never-attempted [relative risk RR 9.27 (95% confidence interval: 1.73-49.82); 2.03 (1.02-3.32), for each standard deviation increase; 1.07 (1.00-1.15); respectively]. Preteen ADHD symptoms increased the risk of attempts persisting into adulthood as compared to never-attempted [RR 2.05 (1.29-3.28) for each standard deviation increase]. Suicide death of schoolmate/acquaintance increased risks of an adulthood trajectory as compared to never-attempted and adolescence-limited [RR 8.41 (3.04-23.27) and 6.63 (1.29-34.06), respectively].

CONCLUSION

In half the participants attempting suicide, attempts continued into adulthood. We stress the need for preventive strategies in early adolescence and differential clinical/educational interventions as identified for each trajectory.

Cohort Profile: Quebec Longitudinal Study of Child Development (QLSCD)

PURPOSE

The Quebec Longitudinal Study of Child Development (QLSCD) was designed to examine the long-term associations of preschool physical, cognitive, social, and emotional development with biopsychosocial development across childhood, adolescence, and young adulthood.

METHODS

QLSCD is an ongoing prospective cohort including 2120 singletons born in 1997/1998 in the Canadian province of Quebec. So far, data have been collected annually or every 2 years from child ages 5 months to 21 years. The cohort currently includes 1245 participants. Data available include a range of environmental (e.g., family characteristics, child behaviour, educational attainment, mental health), biological (e.g., hair cortisol, genetic, epigenetic), and administrative data.

RESULTS

QLSCD has contributed to the understanding of children's psychosocial development, including the development of physical aggression and anxiety. QLSCD articles have advanced scientific knowledge on the influence of early childhood factors on childhood, adolescent, and young adult mental health, including the effect of participation in early childcare on cognitive and behavioural development, the developmental origins of adolescent and young adult mental health problems and suicide risk, and the development of interpersonal difficulties (e.g., peer victimisation) from preschool years to adolescence.

CONCLUSION

QLSCD has given major contributions to our understanding of the link between different aspects of child development and biopsychosocial development during the first two decades of life. Unique features include the presence of environmental, biological, and administrative data, long-term follow-up with frequent data collections, and use of data from multiple informants, including teachers, mothers, fathers, and the children themselves.

Troubling Neurobiological Vulnerability: Psychiatric Risk and the Adverse Milieu in Environmental Epigenetics Research

In post-genomic science, the development of etiological models of neurobiological vulnerability to psychiatric risk has expanded exponentially in recent decades, particularly since the neuromolecular and biosocial turns in basic research. Among this research is that of McGill Group for Suicide Studies (MGSS) whose work centers on the identification of major risk factors and epigenetic traits that help to identify a specific profile of vulnerability to psychiatric conditions (e.g., depression) and predict high-risk behaviors (e.g., suicidality). Although the MGSS has attracted attention for its environmental epigenetic models of suicide risk over the years and the translation of findings from rodent studies into human populations, its overall agenda includes multiple research axes, ranging from retrospective studies to clinical and epidemiological research. Common to these research axes is a concern with the long-term effects of adverse experiences on maladaptive trajectories and negative mental health outcomes. As these findings converge with post-genomic understandings of health and also translate into new orientations in global public health, our article queries the ways in which neurobiological vulnerability is traced, measured, and profiled in environmental epigenetics and in the MGSS research. Inspired by the philosophy of Georges Canguilhem and by literature from the social studies of risk and critical public health, we explore how the epigenetic models of neurobiological vulnerability tie into a particular way of thinking about the normal, the pathological, and the milieu in terms of risk. Through this exploration, we examine how early life adversity (ELA) and neurobiological vulnerability are localized and materialized in those emerging models while also considering their broader conceptual and translational implications in the contexts of mental health and global public health interventions. In particular, we consider how narratives of maladaptive trajectories and vulnerable selves who are at risk of harm might stand in as a "new pathological" with healthy trajectories and resilient selves being potentially equated with a "new normal" way of living in the face of adversity. By troubling neurobiological vulnerability as a universal biosocial condition, we suggest that an ecosocial perspective may help us to think differently about the dynamics of mental health and distress in the adverse milieu.

How Do Cyber Victimization and Low Core Self-Evaluations Interrelate in Predicting Adolescent Problematic Technology Use?

Research has demonstrated that cyber victimization is consistently associated with higher problem behaviors such as problematic technology use. However, little research has examined specific individual dispositions that can serve as a buffer in the link between cyber victimization and higher problematic uses of technology (i.e., problematic Internet, smartphone, and social media), such as core self-evaluations (CSE). A convenience sample of 1211 high school students, 657 females, 554 males, aged 12 to 18 (mean age = 13.74) completed measures of cyber victimization, CSE, and different problematic technology-related behaviors. Results of correlational analysis revealed significant associations between cyber victimization and all problematic uses of technology. Our findings also suggested that high CSE weakened the relationship between cyber victimization and two of the three problematic uses of technology. Consistent with social compensation theory, cyber victimization was concurrently linked to different problematic uses of technology. Low CSE also strengthened the link between cyber victimization and problems use of smartphones and social media and also showed a marginally significant interaction with cyber victimization in predicting problematic Internet use. Implications of these preliminary findings are discussed and avenues for further research are offered.

Machine Learning Assessment of Early Life Factors Predicting Suicide Attempt in Adolescence or Young Adulthood

IMPORTANCE

Although longitudinal studies have reported associations between early life factors (ie, in-utero/perinatal/infancy) and long-term suicidal behavior, they have concentrated on 1 or few selected factors, and established associations, but did not investigate if early-life factors predict suicidal behavior.

OBJECTIVE

To identify and evaluate the ability of early-life factors to predict suicide attempt in adolescents and young adults from the general population.

DESIGN, SETTING, AND PARTICIPANTS

This prognostic study used data from the Québec Longitudinal Study of Child Development, a population-based longitudinal study from Québec province, Canada. Participants were followed-up from birth to age 20 years. Random forest classification algorithms were developed to predict suicide attempt. To avoid overfitting, prediction performance indices were assessed across 50 randomly split subsamples, and then the mean was calculated. Data were analyzed from November 2019 to June 2020.

EXPOSURES

Factors considered in the analysis included 150 variables, spanning virtually all early life domains, including pregnancy and birth information; child, parents, and neighborhood characteristics; parenting and family functioning; parents' mental health; and child temperament, as assessed by mothers, fathers, and hospital birth records.

MAIN OUTCOMES AND MEASURES

The main outcome was self-reported suicide attempt by age 20 years.

RESULTS

Among 1623 included youths aged 20 years, 845 (52.1%) were female and 778 (47.9%) were male. Models show moderate prediction performance. The areas under the curve for the prediction of suicide attempt were 0.72 (95% CI, 0.71-0.73) for females and 0.62 (95% CI, 0.60-0.62) for males. The models showed low sensitivity (females, 0.50; males, 0.32), moderate positive predictive values (females, 0.60; males, 0.62), and good specificity (females, 0.76; males, 0.82) and negative predicted values (females, 0.75; males, 0.71). The most important factors contributing to the prediction included socioeconomic and demographic characteristics of the family (eg, mother and father education and age, socioeconomic status, neighborhood characteristics), parents' psychological state (specifically parents' antisocial behaviors) and parenting practices. Birth-related variables also contributed to the prediction of suicidal behavior (eg, prematurity). Sex differences were also identified, with family-related socioeconomic and demographic characteristics being the top factors for females and parents' antisocial behavior being the top factor for males.

CONCLUSIONS AND RELEVANCE

These findings suggest that early life factors contributed modestly to the prediction of suicidal behavior in adolescence and young adulthood. Although these factors may inform the understanding of the etiological processes of suicide, their utility in the long-term prediction of suicide attempt was limited.

School and Cybervictimization Across High School: Normative Developmental Trajectories and Bidirectional Links with Loneliness

The current study examines normative developmental trajectories of school and cybervictimization across 3 years of high school and tests whether school and cybervictimization experiences predict increases in loneliness at school or whether loneliness at school increases the risk of victimization. Gender differences are also explored. Data were drawn from a longitudinal sample of 4,339 ethnically diverse U.S. adolescents (M_age  = 15.02) who completed surveys in 9th, 10th, and 11th grades. Whereas school victimization decreased, cybervictimization increased across high school. School-based victimization and loneliness were bidirectionally related across time (controlling for cybervictimization), but cybervictimization and loneliness were not related (controlling for school victimization). The findings provide a nuanced account of the associations between school and cybervictimization with feelings of isolation at school.

Editorial: The role of digital technology in children and young people's mental health - a triple-edged sword?

The rapid expansion of access to, and engagement with, the Internet and digital technology over the past 15 or so years has transformed the social, educational and therapeutic space occupied by children and young people in contemporary society in remarkable ways. First, it has created previously unimaginable opportunities for learning and development and personal exploration and growth. Second, it seems that the very same qualities and characteristics of the Internet that make these positive contributions possible, such as its immediacy, portability, intimacy, unconstrained reach and lack of supervision and regulation of content, has opened children and young people up to a range of serious social, intellectual and mental health risks. Finally, over and above these 'effects', the digital space is increasingly successfully being harnessed for the identification and treatment of mental health problems. Accordingly, the Internet is not so much a double-, as a triple-edged sword, with regard to children's mental health.
