Exposure to parental and community violence and the relationship to bullying perpetration and victimization among early adolescents: A parallel process growth mixture latent transition analysis

Exposure to community violence as a mechanism linking neighborhood socioeconomic disadvantage and neural responses to reward

A growing literature links socioeconomic disadvantage and adversity to brain function, including disruptions in reward processing. Less research has examined exposure to community violence (ECV) as a specific adversity related to differences in reward-related brain activation, despite the prevalence of community violence exposure for those living in disadvantaged contexts. The current study tested whether ECV was associated with reward-related ventral striatum (VS) activation after accounting for familial factors associated with differences in reward-related activation (e.g. parenting and family income). Moreover, we tested whether ECV is a mechanism linking socioeconomic disadvantage to reward-related activation in the VS. We utilized data from 444 adolescent twins sampled from birth records and residing in neighborhoods with above-average levels of poverty. ECV was associated with greater reward-related VS activation, and the association remained after accounting for family-level markers of disadvantage. We identified an indirect pathway in which socioeconomic disadvantage predicted greater reward-related activation via greater ECV, over and above family-level adversity. These findings highlight the unique impact of community violence exposure on reward processing and provide a mechanism through which socioeconomic disadvantage may shape brain function.

On the complex relationship between resilience and hair cortisol levels in adolescence despite parental physical abuse: a fourth wave of resilience research

Introduction

To understand the family's role in adolescents' mental health development and the connection to neurodevelopmental disorders related to experienced parental physical abuse, we first explored resilience pathways longitudinally and secondly, connected the identified patterns to adolescents' hair cortisol levels that are rooted in the hypothalamic-pituitary-adrenal axis as the main stress response system and connected brain structure alterations.

Methods

We analyzed longitudinal online questionnaire data for three consecutive high school years (from seventh to ninth grade) and four survey waves from a representative sample of n = 1609 high school students in Switzerland on violence-resilience pathways. Furthermore, we collected students' hair samples from a subsample of n = 229 at survey wave 4. About 30% of the participating adolescents had been physically abused by their parents. Out of the overall sample, we drew a subsample of adolescents with parental abuse experiences (survey wave 1 n = 509; survey wave 2 n = 506; survey wave 3 n = 561; survey wave 4 n = 560).

Results

Despite the odds, about 20-30% of adolescents who have experienced parental physical abuse escaped the family violence cycle and can be called resilient. By applying a person-oriented analytical approach via latent class and transition analysis, we longitudinally identified and compared four distinct violence-resilience patterns. We identified violence resilience as a multidimensional latent construct, which includes hedonic and eudaimonic protective and risk indicators. Because resilience should not solely be operationalized based on the lack of psychopathology, our latent construct included both feeling good (hedonic indicators such as high levels of self-esteem and low levels of depression/anxiety and dissociation) and doing well (eudaimonic indicators such as high levels of self-determination and self-efficacy as well as low levels of aggression toward peers).

Discussion

The present study confirmed that higher cortisol levels significantly relate to the comorbid pattern (internalizing and externalizing symptoms), and further confirmed the presence of lasting alterations in brain structures. In this way, we corroborated the insight that when studying the resilience pathways and trajectories of abused adolescents, biological markers such as hair cortisol significantly enhance and deepen the understanding of the longitudinal mechanisms of psychological markers (e.g., self-determination, self-esteem, self-efficacy) that are commonly applied in questionnaires.

Latent profiles of bullying perpetration and victimization: Gender differences and family variables

BACKGROUND

School bullying is a prevalent issue that threatens the psychological and social well-being of adolescents. However, little research has investigated how gender and family variables were related to bullying-involvement patterns among adolescents with siblings.

OBJECTIVE

This study explored gender differences in the profiles of bullying involvement and the relationship between sibling, parental variables, and these profiles among Chinese adolescents.

PARTICIPANTS AND SETTING

Participants (N = 1,060; 46.0 % boys; Mage = 15.53) were recruited from junior and senior high schools in Jiangxi and Guizhou Provinces, China.

METHODS

Bullying involvement, sibling warmth and conflict, and parental psychological maltreatment and neglect were assessed by self-report questionnaire. Latent profile analysis was used to identify subgroups with distinct bullying involvement patterns, then multiple logistic regressions were performed to investigate the associations between family variables and bullying-involvement subgroups.

RESULTS

We found gender differences in both the latent profiles of bullying involvement and the associations between profiles and family variables. Only boys were identified severe bully-victims (3.39 %), while only girls were categorized as relational bully-victims (20.18 %). Boys and girls were similarly represented among uninvolved students (70.76 % vs. 66.85 %), moderate bully-victims (15.25 % vs. 6.49 %), and victims (10.59 % vs. 6.49 %). Students with more sibling warmth manifested less likelihood of engaging in bullying-related profiles, with more parental psychological maltreatment, and more parental neglect manifested more likelihood of engaging in bullying-related profiles only among girls. While students with more sibling conflict were related to more bullying-related profiles among boys than girls.

CONCLUSIONS

The findings emphasize the importance of developing gender-specific bullying intervention strategies that also consider relevant family factors.

The association between family adversity and youth mental health outcomes

BACKGROUND

The association between family adversity and young people's mental health outcomes in communities that experience economic instability has not been well explored in the South African context. Furthermore, the overtime interaction between resilience factors, family adversity, and young people's psychological functioning in African settings, like South Africa, is under-investigated.

PURPOSE

This study investigates the relationship between family adversity and conduct problems and depression at two-time points in a sample of youths in two South African communities stressed by their dependency on economically volatile oil and gas industries.

METHOD

This article draws on longitudinal data generated by the Resilient Youth in Stressed Environments (RYSE) study in South Africa, which included 914 and 528 (wave 1 and 3) adolescents and emerging adults (14-27-year-olds; M age = 18.36 years) living in Secunda/eMbalenhle and Sasolburg/Zamdela. Participants were sampled at baseline (wave 1) and 18-24 months later (wave 3). They self-reported experience of community violence, family adversity, resilience-enabling resources, conduct difficulties, and depression symptoms. Regression analyses were used to examine the unadjusted and adjusted association of family adversity on conduct problem and depression.

RESULTS

About 60% of participants reported high family adversity. Regressions, however, revealed no association between family adversity and conduct problems and depression cross-sectionally and over time. Individual resilience, biological sex, and experience of victimization in the community, however, were associated with conduct difficulty while all three resilience factors were associated with decreased depression among participants.

CONCLUSION

Our study sheds light on the risk and protective factors for mental health outcomes of adolescents and youths who reside in volatile, turbulent communities and experience ongoing familial challenges. To effectively support the mental well-being of young individuals in such contexts, interventions must consider the potential ambivalence of the resilience factors they aim to strengthen.

Community Violence Exposure and Bullying in Mexican Adolescents. The Mediating Role of Moral Emotions

Community characteristics can explain differences in bullying rates between schools. Underpinned by the social-ecological model, this study examined the relationships among community violence exposure (CVE), moral emotions (guilt and sympathy), and bullying in adolescents. We also explored the moderating role of gender in these relationships. The sample included 915 adolescents (48.6% female and 51.4% male) aged 11-16 (M age = 13.76, SD = 0.82). Students responded to the self-report measures. We used a latent variable structural equation modeling (SEM) approach to examine the relationships between variables. The SEM indicated that CVE was negatively associated with moral emotions (guilt and sympathy) and positively associated with bullying. In addition, CVE had a negative indirect association with bullying through their negative relationship with moral emotions. The structural model is equivalent for both genders, suggesting gender does not moderate these relationships. These findings indicate that CVE are associated with differences in school bullying rates.

Adolescent risk and protection profiles for violence perpetration: Insights for family- and community-based prevention

Youth violence continues to be a major developmental and health concern. Preventative resources at individual, family, and community levels may reduce risk, yet the extent to which youth violence perpetration differs by patterns of risk and protective factors remains unknown. Using data from the Florida Youth Substance Abuse Survey (N = 4630; 49% female; M_age  = 14.69), we conducted person-centered, latent profile analyses to identify four patterns for risk of violence perpetration among middle and high school youth. Youth in the Low Risk-High Protection profile (37%) had low likelihood of violence perpetration. Youth in the Low Risk-Low Protection profile (4%) were characterized by poor family functioning, low school belonging, and low community protection. These youth had similar odds of violence perpetration as youth in the Moderate Risk-Moderate Protection profile (44%), which were elevated compared to the Low Risk-High Protection profile. Youth in the High Risk-Low Protection profile (15%), which had the highest levels of risk factors and lowest levels of protective factors, had the highest likelihood of violence perpetration. The High Risk-Low Protection profile was expected based on past research, but the emergence of the Low Risk-Low Protection profile is a unique contribution to the research. Findings contribute to the literature by going beyond a cumulative risk model, identifying subgroups with various patterns of risk and protection in the population, and highlighting the importance of selected prevention for subgroups of youth with high risk or challenging family and community environments.

Association between Community Violence, Disorder and School Environment with Bullying among School Adolescents in Sao Paulo - Brazil

The role of contextual-level factors in bullying is still not clear, and evidence is mostly from high-income countries. Our objective was to investigate the association between community violence, disorder, school environment and bullying among school adolescents. We used data from a representative sample of 9th grade Brazilian adolescents (n = 2108) from the Sao Paulo Project for the social development of children and adolescents (SP - PROSO). Multilevel logistic regression models stratified by sex were used to assess the association between variables at student and school/neighbourhood level and bullying victimization or perpetration. For both sexes, we found that adolescents who perceived high violence between students and high school disorder were more likely to be bullies and victims. Boys who perceived high community violence and disorder in their neighbourhood were more likely to be bullies (OR_3tertile = 2.73 CI95%: 1.57-4.74). Girls attending schools where the principal reported high community violence and disorder in the neighbourhood (OR_high = 10.24 CI95%: 2.11-49.59) and inside the school (OR_high = 6.83 CI95%: 1.48-31.56) were more likely to be bullies. Boys from schools whose principal perceived violence between students were less likely to be victims (OR_high = 0.35 CI95%: 0.16-0.78) and bullies (OR_high = 0.21 CI95%: 0.07-0.64). Girls attending schools with signs or posters about tolerance/gender equality and about violence were less (OR = 0.12 CI95%: 0.03-0.50) and more likely (OR = 25.88 CI95%: 4.28-156.63) to report being bullies, respectively. Community violence, disorder and school environment were associated with bullying victimization and perpetration among adolescents. Sex-specific associations should be further investigated. Prevention and management of school violence in adolescence should consider contextual-level characteristics.

Witnessing Intimate Partner Violence as a Child and Associated Consequences

Intimate partner violence (IPV) continues to be a global problem. The increasing international research, focussing on children who witness IPV between their parents, indicates that these circumstances might influence children in different ways. Despite these efforts, little evidence stems from Germany. Using data from a German school student survey from 2017 and 2019 (N = 21,382), this paper aims to examine the consequences of witnessing IPV. The present paper takes a closer look at children's violent behaviour, attitudes and quality of life while controlling for other potential influences (e.g. physical and psychological child abuse). Results indicate that IPV has a significant negative effect on children's quality of life, in particular on children's sense of security at home and children's life satisfaction. No other effects were significant. In discussing these complex dynamics, the results of the present study highlight the importance of considering children who witness IPV as direct victims. A home with personal threats cannot provide emotional and physical security. Coping with this absence of a secure base at home may lead to the neglect of important developmental tasks during that time, which can have possible far-reaching implications on different areas of children's lives (e.g. social competence). Further research examining the severity and duration of witnessing IPV within the context of a longitudinal design is recommended.

Challenging the "'Mean Kid"' Perception: Boys' and Girls' Profiles of Peer Victimization and Aggression from 4th to 10th Grades

Student involvement in peer aggression is assumed to include the uninvolved, victims, aggressors, and victim-aggressor groups. Yet, evidence supporting this four-group configuration is equivocal. Although most studies report the four groups, several of the aggressor groups could have been labeled as moderate victim-aggressors. This study first reviews studies identifying subgroups of students involved in verbal, relational, and physical aggression. The study then assesses students' perceived involvement in elementary (n = 2,071; Grades 4-6) and secondary school (n = 1,832; Grades 7-10), as well as the associations with outcomes (school belonging, depressive thoughts, and perceived school violence). Latent profile analysis identified three profiles (uninvolved, victim-only, and victim-aggressor) across all grades and genders. In primary school, the uninvolved, victim, and victim-aggressor respectively included 54.56%, 37.51%, and 7.83% of the girls, and 44.23%, 31.92%, and 23.85% of the boys. In secondary school, the uninvolved, victim, and victim-aggressor respectively included 80.16%, 14.93% and 4.91% of the girls, and 64.31%, 22.95% and 12.74% of the boys. Victims and victim-aggressors reported poorer adjustment than uninvolved students. Victims and victim-aggressors reported lower levels of school belonging and higher levels of depressive thoughts than uninvolved students. Also, victim-aggressors perceived more violence in their school than victims and uninvolved students, and victims perceived more violence than uninvolved students. These findings question the existence of an aggressor-only profile, at least, according to student perception, suggesting the need for a new perspective when intervening with students involved in peer aggression.

Fathers’ parenting stress, parenting styles and children’s problem behavior: the mediating role of parental burnout

Parental duties can be overwhelming, particularly when parents lack sufficient resources to cope with parenting demands, leading to parental burnout. Research has shown that parental burnout is positively related to neglect and abuse behaviors towards their children; however, few studies have examined parental burnout within the family system, including examining parenting styles as an antecedent, and most research has ignored the potential influence of fathers’ parental burnout. This study aimed to explore the influence of fathers’ parenting stress and parenting styles on internalizing and externalizing problem behaviors in a sample of junior high school students and the mediating effect of parental burnout. Questionnaire data from 236 students (56.4% girls) and their fathers (age: M = 39.24, SD = 5.13) were collected on 3 different time points. Fathers were asked to report their parenting stress and parenting styles at Time 1, and parental burnout at Time 2, and students were asked to report their internalizing and externalizing behaviors at Time 3. The results indicated that: (1) fathers’ parenting stress and negative parenting styles were positively related to parental burnout, and fathers’ positive parenting styles were negatively related to parental burnout; (2) fathers’ parental burnout was positively related to children’s internalizing and externalizing problem behavior; and (3) fathers’ parental burnout could mediate the relationship between parenting stress, negative parenting styles, and internalizing and externalizing problem behavior. These results suggested that fathers’ roles in the parenting process were not negligible, and more attention should be given to prevention and intervention methods for fathers’ parental burnout.

Pathways from Exposure to Community Violence to Bullying Victimization among African American Adolescents in Chicago's Southside

The present study proposes and examines the pathways from exposure to community violence to bullying victimization through the influences of depression, exposure to peer delinquency, and drug use among 638 African American adolescents (aged 12-22) from low-resourced neighborhoods in Chicago's Southside. The study found that African American adolescents who were exposed to community violence were likely at risk of bullying victimization, depression, exposure to peer delinquency, and drug use. Depression can heighten the risk of bullying victimization. These findings have implications for future research.

Subtypes of Bullying and Types of Substance Use among Urban African American Adolescents: Who Is Likely to Use What?

The present study examined the types of drugs likely to be used by bullies, victims, and bully/victims. Participants comprise African American adolescents from three high schools, one youth church group, two community youth programs, and four public venues in low-income communities in Chicago's Southside. A series of logistic regression analyses and latent class analyses were employed. Victims are likely to use alcohol, marijuana, and lean/krokodil. Bullies were likely to use alcohol and marijuana. Bully/victims were not at risk of any of the substances. Our LCA findings revealed a lower occurrence of substance use among victims although 30% used alcohol and marijuana; more than half of bullies showed high levels of alcohol, marijuana, and lean/krokodil use; a diverse pattern of drug use was shown among bully/victims although their lean/krokodil and crack/cocaine use was higher than other subgroups of bullying. The drugs of choice for African American bullies, victims, or bully/victims are variable.

Profiles of Community Violence Exposure, Moral Disengagement, and Bullying Perpetration: Evidence from a Sample of Italian Adolescents

According to the Pathologic Adaptation Model of community violence exposure, repeated experiences of violence within the community lead youth to accept violence as a normative and legitimate strategy to cope with conflict, thus increasing their involvement in aggressive behaviors. This hypothesis has been under-investigated with reference to bullying at school. Using a person-centered analytical approach (latent profile analysis), this study examines the mediating role of moral disengagement as a type of normalizing cognition about violence, in the relationship between profiles of community violence exposure and perpetration of bullying. Eight hundred and two adolescents (11-18 years; 43.4% girls) from two different urban and societal contexts in Italy (Milan vs. Naples) participated in the study. Four profiles of exposure to community violence emerged. Context site and age influenced belonging to the four profiles. Being moderately exposed to violence, both as a victim and as a witness, was significantly associated with higher levels of moral disengagement and bullying perpetration. Being exposed as a witness and as a victim, and being exposed only as a witness were associated with bullying perpetration via the increase of moral disengagement. These findings support the Pathologic Adaptation Model and indicate that adolescents who experience higher levels of community violence, as a witness or both as a witness and a victim, are more likely to develop morally disengaged beliefs about violence, which in turn would increase the likelihood to perpetrate bullying. Results are also discussed in the context of social diversity.

Internalizing and Externalizing Symptoms in Adolescents With and Without Experiences of Physical Parental Violence, a Latent Profile Analysis on Violence Resilience

Questionnaire data from a cross-sectional study on social resilience in adolescence, with a sample of N = 1,974 Swiss seventh grade high school students ages 12-14 (M = 11.76; SD = 0.65) was used to identify and compare violence resilience profiles. Person-centered latent profile analysis (LPA) was applied and allowed for the grouping of adolescents into profiles of internalizing (depression/anxiety, dissociation) and externalizing symptoms (peer aggression, peer victimization, classroom disruption) and differentiation of adolescents with (n = 403) and without (n = 1,571) physical parental violence experiences. Subsequently, a multinomial logistic regression analysis was conducted to further investigate the sociodemographic predictors of violence resilience profiles. With LPA, we identified four distinct profiles for both adolescent groups (with and without parental physical violence experiences). The results showed three particularly burdened profiles of adolescents, one with higher externalizing and one with higher internalizing symptoms, which did not occur simultaneously to the same extent. Furthermore, the third profile contained adolescents with both elevated internalizing and externalizing symptoms, the comorbid profile. The fourth profile consisted of the majority of adolescents, who exhibited little or no internalizing and externalizing symptoms, the so-called no/low symptomatic profile. A differentiated view of the symptoms can create added value regarding the understanding of violence resilience. Moreover, in the multinomial logistic regression, significant associations were found between the profiles and adolescents' gender in the group of adolescents with parental physical violence experiences, but none were found in relation to sociocultural status and migration background.

Joint Developmental Trajectories of Bullying and Victimization from Childhood to Adolescence: A Parallel-Process Latent Class Growth Analysis

Previous studies have shown that bullying and victimization can be experienced simultaneously by an individual and can change over time. Understanding the joint longitudinal development of the two is of great significance. We conducted a 4-year longitudinal study to examine the joint developmental trajectories of bullying and victimization, gender and grade differences in trajectory group membership, and changes in specific forms of bullying and victimization (verbal, relational, and physical bullying /victimization) in each trajectory group. A total of 775 children from China participated in our study. The average age of participants at the first wave was 10.90 years (SD = 1.12), and boys accounted for 69.5% of the sample. Based on mean scores, four distinct joint developmental trajectories of bullying and victimization were found: the involvement group (both bullying and victimization increased from low to high over time, accounting for 7.6% of the total), the desisted group (both bullying and victimization decreased from high to low over time, 6.1%), the victimization group (victimization remained at a high level, whereas bullying remained at a low level for 3 years, 13.2%), and the noninvolved group (bullying and victimization remained at a stable low level, 73.1%). Boys were more likely than girls to belong to the involvement group, desisted group, and victimization group, whereas girls were more likely than boys to belong to the noninvolved group. There was no significant grade difference in the trajectory group. All forms of bullying/victimization were consistent with the overall trend and showed similar levels. These results have important implications for the prevention of and interventions for school bullying.

Do Recent Experiences of Sexual Violence and Co-Occurring Depression and Anxiety Symptoms Predict Poorer Functioning One Year Later During the Transition to Young Adulthood?

Sexual violence (SV) is a public health concern for youth. Few longitudinal studies address how experiences of SV and co-occurring depression and anxiety symptoms in early young adulthood may contribute to poorer functioning in young adulthood. Using a sample of 2,416 youth aged 18 to 20 (Time 1), we assessed past year SV and co-occurring depression and anxiety symptoms. One year later, when youth were between the ages of 20 and 22 (Time 2), participants indicated their functioning in four domains: physical health and sleep quality, substance use consequences, psychological functioning, and social functioning. Using latent class analyses, we found six participant classes at Time 1 based on SV experiences and co-occurring depression and anxiety symptoms. Classes were variable by participants' reported degree of SV experiences and co-occurring depression and anxiety symptomology. Longitudinal analyses indicated that youth in a class that experienced high levels of both SV and co-occurring depression and anxiety at Time 1 generally reported the poorest functioning in all key domains at Time 2. However, classes where participants reported greater depression and anxiety symptoms-most often in the presence of, but at times in the absence of, SV-were consistently associated with poorer functioning for physical health, psychological functioning, and social health. Classes where participants reported greater SV-in the presence of, but at times in the absence of, depression and anxiety symptoms-were associated with greater alcohol and marijuana consequences. Findings suggest prevention of SV, accessible counseling for those that have experienced SV, and screening to identify and intervene to address depression and anxiety may all be essential to help prevent poorer functioning in young adulthood.

Who beats their partner, and who beats their schoolmates? A comparison of teen dating and school physical violence perpetration in Lower Saxony, Germany

Teen dating violence (TDV) and school violence (SV) are two major social problems in adolescence. Until recently, the antecedents of both TDV and SV have been analyzed largely independently of each other. This study analyses and compares the determinants of both TDV and SV, with a focus on physical violence. Based on a comprehensive survey of ninth‐grade adolescents at the average age of 15 years (N = 3,800) conducted in the German federal state of Lower Saxony, the findings showed that there is a significant but low correlation between both physical TDV and SV (r = 0.21). Concerning the determinants, we found that males carry out physical SV significantly more often, but physical TDV significantly less often than female respondents. Acquaintance with violent friends shows a stronger correlation with SV but not with TDV. Low self‐control and violent media consumption are determinants of both TDV and SV. Empathy as a protective factor and parental violence as another risk factor were found to be only weak and sometimes not significantly correlated with both TDV and SV.

Longitudinal effects of adverse childhood experiences on substance use transition patterns during young adulthood

BACKGROUND

Few studies have investigated how adverse childhood experiences are associated with substance use patterns during young adulthood, a crucial developmental period.

OBJECTIVE

The objective of this study was to extend current knowledge on the association between adverse childhood experiences and patterns of substance use among young adults. We also sought to understand how current mental health status and biological sex influences these patterns.

PARTICIPANTS AND SETTING

The current study utilized wave 8-wave 11 data of a longitudinal cohort study (N = 2880).

METHODS

We used latent transition analysis (LTA) to understand stability and transition patterns of substance use across participants who reported adverse childhood experiences (ACEs+) versus those who did not (ACEs-). Latent class regression was used to assess contemporaneous effects of mental health and sex on classes over time.

RESULTS

Both groups had similar patterns of substance use emerge at each timepoint: High all; Binge, tobacco, cannabis; and Steady/increasing binge drinking. ACEs+ had a higher proportion of youth in the High all class and much higher stability in this class, compared to the ACEs- group. Those in the ACES+ group were less likely to transition out of a riskier class. Mental health and sex showed differential effects across ACEs groups.

CONCLUSION

Results point to increased risk of polysubstance use, including opioids and prescription medications, among those who reported adverse childhood events. Future work may explore protective, malleable, factors that may confer reduced risk of long-term polysubstance use.

Pathways From Witnessing Parental Intimate Partner Violence to Involvement in Bullying: Empirically Testing a Proposed Conceptual Framework

We tested a proposed conceptual framework in which we hypothesized that witnessing parental intimate partner violence (witnessing parental IPV) is linked to children's bullying and peer victimization. We also hypothesized that the relationship between witnessing parental IPV and bullying and peer victimization in childhood would be mediated by increased psychological problem behavior, school absences, and problematic peer interactions. We utilized data from the National Survey of Children's Health. We found that witnessing parental IPV was positively related to children's bullying and peer victimization not only directly, but also indirectly through the mediating role of psychological problem behavior, school absences, and problematic peer interactions. Our findings highlight the importance of exploring the mechanisms by which bullying and peer victimization increase in those who have witnessed parental IPV.

Effects of a Whole-School Health Intervention on Clustered Adolescent Health Risks: Latent Transition Analysis of Data from the INCLUSIVE Trial

Whole-school interventions are a promising approach to preventing bullying and aggression while promoting broader health. The main analyses from a trial of the INCLUSIVE whole-school intervention reported reductions in bullying victimisation but not aggression and improved mental well-being. Latent transition analysis can examine how interventions ‘move’ people between classes defined by multiple outcomes over time. We examined at baseline what classes best defined individuals’ bullying, aggression and mental well-being and what effects did the intervention have on movement between classes over time? INCLUSIVE was a two-arm cluster-randomised trial with 20 high schools per arm, with 24-month and 36-month follow-ups. We estimated sequential latent class solutions on baseline data. We then estimated a latent transition model including baseline, 24-month and 36-month follow-up measurements. Our sample comprised 8179 students (4082 control, 4097 intervention arms). At baseline, classes were (1) bullying victims, (2) aggression perpetrators, (3) extreme perpetrators and (4) neither victims nor perpetrators. Control students who were extreme perpetrators were equally likely to stay in this class (27.0% probability) or move to aggression perpetrators (25.0% probability) at 24 months. In the intervention group, fewer extreme perpetrators students remained (5.4%), with more moving to aggression perpetrators (65.1%). More control than intervention extreme perpetrators moved to neither victims nor perpetrators (35.2% vs 17.8%). Between 24 and 36 months, more intervention students moved from aggression perpetrators to neither victims nor perpetrators than controls (30.1% vs 22.3%). Our findings suggest that the intervention had important effects in transitioning students to lower-risk classes.

Association between aggressive and non-fatal suicidal behaviors among U.S. high school students

OBJECTIVE

This study quantified the association between aggressive and non-fatal suicidal behaviors (NFSB) among U.S. high school students and examined whether the association could be explained by substance use, bullying and sexual/dating violence victimization, and other potential risk factors.

METHOD

Data were based on self-reports from 14,765 students who responded to the 2017 National Youth Risk Behavior Survey. Confirmatory latent class analysis (LCA) identified two distinct, dichotomous latent class variables manifested by indicators of past-year NFSB (i.e., ideation, plan, and attempt) and aggressive behavior (i.e., physical fighting in general and on school property). The structural model estimated the odds ratios between NFSB, aggressive behavior, and their potential risk factors.

RESULTS

Without adjusting for covariates, the confirmatory LCA estimated an odds ratio (OR) of 2.55 (95% confidence interval [CI]: 1.93, 3.37) between two latent class variables for violence against self (NFSB) and others (physical fighting). The net association, however, was rendered nonsignificant (OR = 1.08 [95% CI: 0.88, 1.31]) when adjusted for covariates. Significant common risk factors included exposure to physical dating violence, being bullied on school property and/or electronically, being threatened or injured by someone with a weapon on school property, and lifetime illegal drug use and prescription opioid misuse.

LIMITATIONS

Cross-sectional data do not allow assessment of causal relationships.

CONCLUSIONS

Findings elucidated the association between NFSB and aggressive behavior, with serious implications for prevention and intervention. Targeting substance use, bullying, and sexual and dating violence will protect students from engaging in both types of violent behaviors.

Victims, bullies and bully-victims: prevalence and association with negative health outcomes from a cross-sectional study in São Paulo, Brazil

OBJECTIVES

To estimate the prevalence of self-reported bullying as victims, bullies or bully-victims among 9th grade adolescents in the city of São Paulo, Brazil; to investigate association between bullying with negative health outcomes.

METHODS

Cross-sectional data were obtained in 2017 from a sample of Brazilian adolescents (n = 2680) using a structured, self-administered questionnaire. Bivariate and multivariate Poisson regression were employed to assess in which extent the experience of bullying in position of victim, bully or bully-victim affects adolescents' health.

RESULTS

Prevalence of bullying victimization was 18.3%, while victimization/perpetration and perpetration corresponded to 10.42% and 4.9%, respectively. Adolescents who experienced bullying victimization were more likely to present high levels of internalizing symptoms, to report self-harm, to present negative self-rated health and to use tobacco, when compared with those not involved. Bullies were more likely to use alcohol and to binge drinking. bully-victims presented a higher prevalence of all health outcomes, except for tobacco use.

CONCLUSIONS

Our findings highlight the effect of bullying in adolescents' health, regardless of the position. Planned intersectoral efforts between parents, health and education systems to prevent bullying could therefore reduce negative health outcomes during adolescence.

Family Violence, Sibling, and Peer Aggression During Adolescence: Associations With Behavioral Health Outcomes

Bullying and sibling aggression can appear as similar behavior, though the latter is comparatively understudied. Aligned with the Theory of Intergenerational Transmission of Violence, research suggests that exposure to family violence increases an individual's risk for perpetrating violence in their own future relationships. Additionally, Problem Behavior Theory suggests that engaging in one problem behavior (e.g., bullying) increases the likelihood of engaging in other problem behavior (e.g., substance use). In Phase 1, this study of middle school students from the U.S. examined how exposure to family violence predicted membership in latent classes of bullying and sibling aggression perpetration (N = 894, sampled from four middle schools). In Phase 2, we used mixture modeling to understand how latent classes of family violence, sibling aggression, and bullying predict future substance use, mental health outcomes, and deviance behavior later in high school. Results yielded four profiles of peer and sibling aggression: high all, high sibling aggression, high peer aggression, and low all aggression. Youth who reported witnessing more family violence at home were significantly more likely to fall into the sibling aggression only and high all classes, compared to the low all class. Phase 2 results also yielded four classes: a high all class, a sibling aggression and family violence class, a peer aggression class, and a low all class. Individuals in the high all class were more likely to experience several unfavorable outcomes (substance use, depression, delinquency) compared to other classes. This study provides evidence for pathways from witnessing violence, to perpetrating aggression across multiple contexts, to developing other deleterious mental and behavioral health outcomes. These findings highlight the negative impact family violence can have on child development, providing support for a cross-contextual approach for programming aimed at developing relationships skills.

Pathways Linking Exposure to Community Violence, Self-serving Cognitive Distortions and School Bullying Perpetration: A Three-Wave Study

School bullying is a social phenomenon stemming from a complex interrelationship between the individuals and their environments. Underpinned by the social-ecological models, this study investigated the mediation of self-serving cognitive distortions (CDs) in the relationship between community violence exposure, as a victim and as a witness, and bullying perpetration. Bidirectional associations between violence exposure and bullying perpetration, and between CDs and bullying perpetration over time were also hypothesized. The study used a three-waves cross-lagged panel modeling in a sample of 829 Italian high school adolescents (46% males; Mage [Time 1; T1] = 12.71; Standard deviation [SD] = 1.68). The results showed that being exposed to community violence as a witness at T1 increased the development of CDs at Time 2 (T2), which in turn promoted the bullying perpetration at Time 3 (T3). Being exposed to community violence as a victim was not a significant predictor of CDs and bullying perpetration over time. Bidirectional associations were found between witnessing violence and bullying perpetration, and between CDs and bullying perpetration. The association between community violence exposure and individual moral cognitions over time plays a crucial role in predicting bullying perpetration. These findings highlight the need to consider both contextual and individual factors in understanding and preventing bullying perpetration.

Effects of measurement timing on subgroup identification using growth mixture modeling: An empirical application to alcohol use

Growth mixture modeling (GMM) identifies latent classes exhibiting distinct longitudinal patterns on an outcome. Subgroups identified by GMM may be artifactually influenced by measurement timing (e.g., timing of the initial assessment, length of the interval from the first to the last assessment, and total number of assessments) as well as the theoretically posited developmental patterns of the behavior. The current study investigated this possibility using alcohol data from the 1997 National Longitudinal Survey of Youth (n = 2686; 49.44% female; 71.84% White). Three assessment configurations were examined: all 12 waves, first 6 waves, and last 7 waves. Five subgroups were identified using all 12 waves: Normative (71.33%), Low-Increasing (8.45%), Low-Steady (8.97%), High-Slowly Decreasing (7.67%), and Extreme-Sharply Decreasing (3.57%). When comparing participants' subgroup membership for all 12 waves to the first six waves, 14% of the sample was differentially classified. When comparing all 12 waves to the last seven waves, 62% of the sample was differentially classified. Alterations in the timing of the initial assessment had a substantial impact on latent class estimation, underscoring the importance of selecting the developmental window a priori based on theory and empirical knowledge. The time-bounded nature of mixture modeling solutions (i.e., a selected developmental window within the course of a phenomenon) suggests that the latent subgroups should not be interpreted as representing subgroups that are present in the population. Future directions and strategies for testing alternative interpretations are presented. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Extending poly-victimization theory: Differential effects of adolescents' experiences of victimization on substance use disorder diagnoses upon treatment entry

BACKGROUND

Although victimization is a known contributor to the development of substance use disorders, no research has simultaneously examined how characteristics of victimization experienced over time, such as the type of abuse, the presence of poly-victimization, closeness to perpetrator(s), life threat or fear, and negative social reactions to disclosing victimization, cluster into profiles that predict substance use disorders.

OBJECTIVE

The aim of the current study is to assess how profiles of victimization and trauma characteristics are associated with substance use disorders and assess potential gender differences.

PARTICIPANTS AND SETTING

Participants were 20,092 adolescents entering substance use treatment.

METHODS

We used latent class and multi-group latent class analysis to extract classes of victimization and associated characteristics. Emergent classes were used to predicted substance use disorder status at treatment intake.

RESULTS

Five classes were extracted: poly-victimization + high harmful trauma characteristics, sexual abuse + negative social reaction and perceived life threat, emotional abuse + trusted perpetrator, physical abuse and low all. Similar classes were found for the multi-group model. In both the overall and female-specific models, the poly-victimization + high harmful trauma characteristics class was more severe than all other classes in terms of opioid use disorder, tobacco use disorder, and dual diagnosis. Other class differences were found across gender.

CONCLUSIONS

Adolescents entering treatment can be distinguished by their profiles of victimization experiences and associated characteristics, and these profiles evidence different associations with substance use disorder diagnoses. Results point to a need for more nuanced assessment of victimization experiences and gender-specific interventions.
