Depressive symptomatology as a predictor of exposure to intimate partner violence among US female adolescents and young adults

OBJECTIVE: To examine whether depressive symptomatology is predictive of subsequent intimate partner violence victimization among a national prospective sample of female adolescents and young adults. DESIGN: Home interview data from 2 waves of the school-based National Longitudinal Study of Adolescent Health were used to examine whether baseline depressive symptomatology was associated with increased risk of past-year exposure to physical abuse by a current partner at 5-year follow-up, controlling for age, race/ethnicity, parental education, retrospective childhood physical and sexual abuse, and baseline dating violence and forced sex. SETTING: A stratified random sample of 80 US high schools and 52 middle schools. PARTICIPANTS: All young women (n = 1659) were in a current opposite-sex relationship at follow-up. MAIN EXPOSURE: Baseline past-week depressive symptomatology, measured as both a dichotomous and continuous variable. MAIN OUTCOME MEASURES: Past-year exposure to mild and moderate to severe physical abuse by a current intimate partner. RESULTS: In adjusted models with dichotomous depressive symptoms, high baseline symptom levels were associated with 1.86 times the odds of subsequent exposure to moderate to severe partner violence (95% confidence interval, 1.05-3.29). In adjusted models with continuous depressive symptoms, an increase of 1 SD in baseline symptom levels was associated with a 24% increase in odds of exposure to mild partner violence and a 24% increase in the odds of exposure to moderate to severe partner violence. CONCLUSIONS: The findings of this study suggest that depressive symptomatology among girls during adolescence is associated with increased risk of subsequent exposure to physical partner violence. Prevention, identification, and treatment of depressive symptomatology among adolescent girls may help to reduce the likelihood of subsequent victimization.     

Cyberbullying and Sleep Disturbance Among Early Adolescents in the U.S.

ObjectiveTo determine the association between cyberbullying (victimization and perpetration) and sleep disturbance among a demographically diverse sample of 10–14-year-old early adolescents.MethodsWe analyzed cross-sectional data from the Adolescent Brain Cognitive Development (ABCD) Study (Year 2, 2018–2020) of early adolescents (10–14 years) in the US. Modified Poisson regression analyses examined the association between cyberbullying and self-reported and caregiver-reported sleep disturbance measures.ResultsIn a sample of 9,443 adolescents (mean age 12.0 years, 47.9% female, 47.8% white), 5.1% reported cyberbullying victimization, and 0.5% reported cyberbullying perpetration in the past 12 months. Cyberbullying victimization in the past 12 months was associated with adolescent-reported trouble falling/staying asleep (risk ratio [RR] 1.87, 95% confidence interval [CI] 1.57, 2.21) and caregiver-reported overall sleep disturbance of the adolescent (RR: 1.16 95% CI 1.00, 1.33), in models adjusting for sociodemographic factors and screen time. Cyberbullying perpetration in the past 12 months was associated with trouble falling/staying asleep (RR 1.95, 95% CI 1.21, 3.15) and caregiver-reported overall sleep disturbance of the adolescent (RR: 1.49, 95% CI 1.00, 2.22).ConclusionsCyberbullying victimization and perpetration are associated with sleep disturbance in early adolescence. Digital media education and counseling for adolescents, parents, teachers, and clinicians could focus on guidance to prevent cyberbullying and support healthy sleep behavior for early adolescents.     

Demographic,intrinsic, and extrinsic factors associated with weapon carrying at school

BACKGROUND: Recent incidents of school violence have heightened the need to identify societal, interpersonal, and adolescent characteristics that contribute to weapon carrying. OBJECTIVES: To assess the prevalence of weapon carrying at school and to determine associated risk factors for adolescent males and females. DESIGN: A cross-sectional study using the 1994-1995 National Longitudinal Study of Adolescent Health data. PARTICIPANTS: A nationally representative sample of 6504 adolescents and their parents. MAIN OUTCOME MEASURE: Whether adolescents have ever carried a weapon at school. STATISTICS: chi(2) Analyses and hierarchical regressions were done using SPSS (SPSS Inc, Chicago, Ill) and SUDAAN (Research Triangle Park, NC) software. Regression models included demographic, intrinsic, and extrinsic factors. RESULTS: Of the overall sample, 9.3% (n = 595) reported having carried a weapon at school. Of these, 77% were male (male vs female adjusted odds ratio [AOR], 3.1; 95% confidence interval [CI], 2.3-4.1). Substance use, school problems, perpetration of violence, and witnessing violence were significantly associated with weapon carrying for both males and females. However, for males, extrinsic factors were more important in mediating the effects of substance use and perpetration of physical violence on school weapon carrying, while intrinsic factors mediate these variables for females. CONCLUSION: These findings suggest that interventions for violence prevention for males and females need to be targeted toward different areas.     

Violence risk and protective factors among youth held back in school.

OBJECTIVE: To identify risk and protective factors for violence perpetration among youth with a history of grade retention. DESIGN: Longitudinal analysis of in-home interviews of 13,781 adolescents in grades 7 through 12 conducted in 1995 and 1996. METHODS AND MEASURES: Serious interpersonal violence perpetration at time 2 by time 1 independent variables including measures of community and school context, family context, and individual characteristics. RESULTS: The 20% of girls and 28% of boys who had repeated 1 or more grades were more likely than those who had not to be in the top quintile of violence perpetration at time 2 (P <.001). For both girls and boys with a history of grade repetition, predictive risk factors with an odds ratio of 3 or greater (P <.001) included time 1 violence perpetration, violence victimization, weapon carrying, school problems, and alcohol and marijuana use. Although a high grade point average was a significant protective factor against violence perpetration for both girls (odds ratio, 0.36; P <.05) and boys (odds ratio, 0.23; P <.001), performance on a validated measure of verbal knowledge was not associated with violence perpetration over the study period. School connectedness, parent-family connectedness, and emotional well-being were also significant universal protectors against violence perpetration. CONCLUSIONS: Youth who are held back in school are at heightened risk for violence perpetration. Violence-related behaviors and substance use considerably increase the likelihood of this outcome. The findings suggest that schools can participate in violence prevention by providing youth with a positive community and academic experience.     

Posttreatment victimization and violence among adolescents following residential drug treatment

This article examines the relationships among experiences of childhood abuse, psychiatric disorders, self-reported victimization, and violent behavior, with a focus on gender differences. Data were obtained from treatment entry and 5-year post-treatment interviews of 446 adolescent clients in therapeutic community (TC) drug treatment programs throughout the United States and Canada. Fifty-eight percent of the sample indicated that they engaged in serious violent behaviors (e.g., beatings, threatening or using weapons against other people, or violent crimes such as assaults, rapes, murders) in the 5 years following their separation from TC treatment. Multivariate logistic regression analyses revealed that victimization in the posttreatment period was the most significant factor associated with violent behavior, and pretreatment childhood abuse experiences and psychiatric disorders were not significantly related to the odds of violent behavior. There were significant gender differences in self-reported victimization and violent behavior. The findings suggest that violence in young adulthood for males is related to increasing involvement in violent lifestyles that include drug trafficking, while violence among females is associated with the social and psychological consequences of drug involvement and victimization. High rates of violent involvement and victimization among former adolescent clients suggests the utility of incorporating interventions such as safety-oriented strategies for females or interventions that address involvement in the drug use lifestyles (i.e., use and dealing) for both males and females into residential treatment to reduce the likelihood of future violence.     

Social Epidemiology of Early Adolescent Cyberbullying in the United States

ObjectiveTo determine the prevalence and sociodemographic correlates of cyberbullying victimization and perpetration among a racially, ethnically and socioeconomically diverse population-based sample of 11–12-year-old early adolescents.MethodsWe analyzed cross-sectional data from the Adolescent Brain Cognitive Development (ABCD) Study (Year 2; N = 9429). Multiple logistic regression analyses were used to estimate associations between sociodemographic factors (sex, race/ethnicity, sexual orientation, country of birth, household income, parental education) and adolescent-reported cyberbullying victimization and perpetration.ResultsIn the overall sample, lifetime prevalence of cyberbullying victimization was 9.6%, with 65.8% occurring in the past 12 months, while lifetime prevalence of cyberbullying perpetration was 1.1%, with 59.8% occurring in the past 12 months. Boys reported higher odds of cyberbullying perpetration (AOR 1.71, 95% CI 1.01–2.92) but lower odds of cyberbullying victimization (AOR 0.80, 95% CI 0.68–0.94) than girls. Sexual minorities reported 2.83 higher odds of cyberbullying victimization (95% CI 1.69–4.75) than nonsexual minorities. Lower household income was associated with 1.64 (95% CI 1.34–2.00) higher odds of cyberbullying victimization than higher household income, however household income was not associated with cyberbullying perpetration. Total screen time, particularly on the internet and social media, was associated with both cyberbullying victimization and perpetration.ConclusionsNearly one in 10 early adolescents reported cyberbullying victimization. Pediatricians, parents, teachers, and online platforms can provide education to support victims and prevent perpetration for early adolescents at the highest risk of cyberbullying.     

Prospective effects of violence exposure across multiple contexts on early adolescents’ internalizing and externalizing problems

Background: Violence exposure within each setting of community, school, or home has been linked with internalizing and externalizing problems. Although many children experience violence in multiple contexts, the effects of such cross‐contextual exposure have not been studied. This study addresses this gap by examining independent and interactive effects of witnessing violence and victimization in the community, home, and school on subsequent internalizing and externalizing problems in early adolescence. Methods: A community sample of 603 boys and girls (78% African American, 20% Caucasian) participated in a longitudinal study of youth violence. During two assessments 16 months apart, adolescents reported on witnessing violence and victimization in the community, school, and home, and their internalizing and externalizing problems. Results: Multiple regressions tested the independent and interactive effects of witnessing violence or victimization across contexts on subsequent adjustment, after controlling for initial levels of internalizing and externalizing problems and demographic covariates. Witnessing violence at school predicted anxiety and depression; witnessing at home was related to anxiety and aggression; and witnessing community violence predicted delinquency. Victimization at home was related to subsequent anxiety, depression, and aggression; victimization at school predicted anxiety; and victimization in the community was not independently related to any outcomes. Finally, witnessing violence at home was associated with more anxiety, delinquency, and aggression only if adolescents reported no exposure to community violence. Conclusions: Violence exposure at home and school had the strongest independent effects on internalizing and externalizing outcomes. Witnessing community violence attenuated the effects of witnessing home violence on anxiety and externalizing problems, perhaps due to desensitization or different norms or expectations regarding violence. However, no comparable attenuation effects were observed for victimization across contexts.     

Dating violence, sexual assault, and suicide attempts among urban teenagers

OBJECTIVE: To evaluate the relationship between dating violence, sexual assault, and suicide attempts among urban adolescents. DESIGN: Secondary analysis of the 2005 New York City Youth Risk Behavior Survey. SETTING: Eighty-seven New York City public high schools. PARTICIPANTS: Representative population-based sample of 8080 students, 14 years and older. MAIN EXPOSURES: Dating violence in the past year and lifetime history of sexual assault. OUTCOME MEASURE: One or more suicide attempts in the past year. RESULTS: Respondents were 50.0% female and primarily black (36.0%) or Hispanic (40.1%). In the past year, 11.7% of females and 7.2% of males reported 1 or more suicide attempts. Lifetime history of sexual assault was reported by 9.6% of females and 5.4% of males. Dating violence in the past year was reported by 10.6% of females and 9.5% of males. In multivariate models, controlling for persistent sadness, sexual orientation, and significant risk behaviors, recent dating violence (odds ratio, 1.61; 95% confidence interval, 1.05-2.47) was associated with suicide attempts in adolescent girls, while lifetime history of sexual assault (odds ratio, 3.86; 95% confidence interval, 2.11-7.06) was associated with suicide attempts in adolescent boys. CONCLUSIONS: In this population of urban youth, recent dating violence among females and lifetime history of sexual assault among males were significantly associated with suicide attempts. Clinicians and educators should be trained to routinely screen adolescents for violence victimization and should have a low threshold for referring these at-risk teenagers for mental health services.     

Predictors and protective factors for adolescent Internet victimization: results from a 2008 nationwide Danish youth survey

Aim: To examine the rate of Internet victimization in a nationally representative sample of adolescents aged 14–17 and to analyze predictors and protective factors for victimization. Methods: Data were collected for 3707 pupils in Danish schools in 2008, using a multimedia computer‐based self‐interviewing programme. Family characteristics, alcohol and drug abuse, exposure to physical/sexual abuse, emotional problems, social conduct and own risky Internet behaviour were included in the analyses. Results:  Any online victimization was reported by 27% of the adolescents, most frequently a rumour spread online (9% of boys and 15% of girls) and sexual solicitation (5% of boys and 16% of girls). Parental surveillance of adolescents’ Internet use significantly reduced their risk of online victimization. Roughly half of the adolescents had met Internet acquaintances face to face, with few instances resulting in forced sex (five boys and nine girls). Female gender, parental physical violence, previous exposure to sexual abuse, alcohol abuse in the family, self‐reported emotional problems and antisocial behaviour and high Internet use were all weakly and risky online behaviour strongly associated with online victimization. Conclusions: Danish adolescents are generally aware of the principles of ‘safe chatting’; however, online harassment is relatively frequent, but offline victimization based on Internet acquaintances is rare.     

Violence perpetration among urban american Indian youth: can protection offset risk?

OBJECTIVE: To predict the likelihood of violence perpetration given various combinations of the most statistically salient risk and protective factors related to violence perpetration. DESIGN: Urban Indian Youth Health Survey, conducted from October 9, 1995, to March 30, 1998, consisting of 200 forced-choice items exploring values, cultural identity, relationships, decision-making skills, and health and well-being. SETTING: Urban schools and an after-school youth development program at an urban American Indian center. PARTICIPANTS: Five hundred sixty-nine urban American Indian youth enrolled in grades 3 through 12. MAIN OUTCOME MEASURES: Violence perpetration dichotomized in 2 ways: (1) level of violence perpetration (ie, hitting someone 1-2 times in the past year vs picking fights, hitting repeatedly, participating in group fights, or shooting or stabbing someone in the past year) and (2) having shot and/or stabbed someone during the past year. RESULTS: In the final multivariate models with age as a covariate, most protective against violence perpetration were connections to school (odds ratio [OR], 0.17), positive affect (OR, 0.29), and peer prosocial behavior norms against violence (OR, 0.35). School connectedness (OR, 0.01) and positive affect (OR, 0.46) were also protective against shooting and/or stabbing someone, as was parental prosocial behavior norms against violence (OR, 0.23). The strongest risk factors for violence perpetration were substance use (OR, 2.60) and suicidal thoughts/behaviors (OR, 2.71); for shooting and/or stabbing, it was substance use (OR, 5.26). The likelihood of violence perpetration increased markedly (from 10% to 85%) as the exposure to risk factors increased and protective factors decreased. For shooting or stabbing someone, the probabilities ranged from 3% (0 risks and 3 protective factors) to 64% (1 risk and 0 protective factors). CONCLUSION: The dramatic reduction in the likelihood of violence involvement when risk was offset with protective factors in the probability profiles suggests the utility of a dual strategy of reducing risk while boosting protection.     

Child maltreatment and adulthood violence: the contribution of attachment and drug abuse

This study examined the association between child maltreatment and adult violence in a high-risk sample of women with and without a history of cocaine abuse and the contribution of working models of childhood attachment relationships in understanding this association. Results indicated that whereas childhood physical abuse was associated with adult sexual victimization for cocaine-abusing women, sexual abuse was associated with both partner violence victimization and perpetration for comparison women. Insecure working models of attachment were associated with partner violence victimization for comparison women, independent of the effect of sexual abuse. These findings suggest the importance of research focused on understanding the processes by which child maltreatment may lead to later violence and that examines both childhood and adulthood experiences in understanding pathways to adult violence.     

Self‐reported violence amongst adolescents in Denmark: is alcohol a serious risk factor?

AIM: To describe the prevalence of adolescents' exposure to different types of violence (at home and outside the home) and associations between severe violence and alcohol consumption, taking account of gender and the influence of other factors. METHODS: A multimedia computer-based survey amongst a nationally representative sample of 9th grade pupils included comprehensive data on exposure to physical violence, use of alcohol and additional socio-demographic and behavioural factors. Analyses included gender disaggregated cross tabulations and logistic regressions. RESULTS: Around 9.3% of girls and 12.3% of boys reported being victims of physical violence within the last 12 months. Also, 2.7% of girls and 3.5% of boys reported severe violence. Gender differences existed in place of occurrence; girls were more frequently assaulted at home, boys outside the home. Alcohol was only associated with violence exposure outside the home for boys, not girls. CONCLUSIONS: About one-tenth of adolescents in Denmark reported exposure to any physical violence and 3% to severe violence during the last year. Alcohol consumption was not a risk factor for girls and only a risk factor for boys regarding violence occurring outside the home.     

Randomized trial of brief office-based interventions to reduce adolescent alcohol use

OBJECTIVE: To determine whether office-based interventions change adolescents' alcohol beliefs and alcohol use. DESIGN: Randomized, controlled trial. SETTING: Five managed care group practices in Washington, DC. PARTICIPANTS: Consecutive 12- to 17-year-olds (N = 409) seeing primary care providers (N = 26) for general check-ups. Most of the adolescents (79%) were African American, 44% were male, and 16% currently drank. INTERVENTIONS: Usual care (Group I), adolescent priming with alcohol self-assessment just prior to check-up (Group II), adolescent priming and provider prompting with adolescent self-assessment and brochure (Group III). MAIN OUTCOME MEASURES: Adolescent alcohol beliefs at exit interview and self-reported behaviors at 6- and 12-month follow-up. RESULTS: At exit interview, Groups II and III reported that less alcohol was needed for impaired thinking and a greater intent to drink alcohol in the next 3 months than Group I. At 6 months, Group III reported more resistance to peer pressure to drink, and Groups II and III reported more bingeing than Group I. At 1-year follow-up, controlling for baseline levels, Groups II (odds ratio [OR], 3.44; 95% confidence interval [CI], 1.44-6.24) and III (OR, 2.86; CI, 1.13-7.26) reported more bingeing in the last 3 months than Group I. Group II reported more drinking in the last 30 days (OR, 2.31; CI, 1.31-4.07) and in the last 3 months (OR, 1.76; CI, 1.12-2.77) than Group I. CONCLUSION: Brief office-based interventions were ineffective in reducing adolescent alcohol use but may increase adolescent reporting of alcohol use.     

Exposure to violence and victimization, depression, substance use, and the use of violence by young adolescents

OBJECTIVE: To examine the relationships among exposure to violence; tobacco, alcohol, and other substance use; depression; church attendance; and the use of violence among very young adolescents. METHODS: An 86-item confidential questionnaire was administered to 722 sixth grade students (mean age = 11.9+/-0.8 years) attending 4 middle schools serving neighborhoods in and around public housing. RESULTS: Boys had a higher mean violence scale score than girls (P < or =.0001), and students living in public housing had higher violence scale scores than other students (P< or =.0001). Self-reported use of violence was significantly associated with exposure to violence (r =.45); age (r =.28); frequency of church attendance (r = -.14); depression (r =.28); the probability of being alive at age 25 (r = -.09); the frequency of use of cigarettes (r =.39), alcohol (r =.37), and multiple substances (r =.38); and interest in a gang (r =.37). When all of these variables were analyzed with multiple linear regression, multiple substance use, exposure to violence, interest in a gang, male gender, cigarette smoking, and depression level accounted for 49.7% of the variation in the use of violence scale. CONCLUSION: Recent multiple substance use and lifetime exposure to violence and victimization were the strongest correlates with the frequency that these youth reported using violence and carrying weapons.     

Exposure to violence and victimization and the use of violence by adolescents in the United States.

Violence by adolescents in the United States is of growing concern. Despite a decrease in the rate of violence and death by firearms, firearm injuries are the second leading cause of death among Americans age 15 to 24 and the third leading cause of death among 10- to 14-year-old children. Although there are many factors associated with the use of violence by youths, exposure to violence and victimization has consistently been a predictor of the use of violence, as well as intentions to use violence, carrying a gun, and having attitudes accepting of the use of violence and aggressive behavior to resolve conflict. Adolescents' families, friends, neighborhoods, schools, and the media provide sources of exposure and victimization related to the use of violence. The cultural transmission of deviant behavior theory establishes a framework for understanding the influence of exposure to violence and victimization from these sources on adolescents' use of violence.     

Neighborhood predictors of concealed firearm carrying among children and adolescents: results from the project on human development in Chicago neighborhoods

BACKGROUND: Previous studies of concealed firearm carrying among children and adolescents have focused on individual risk factors. OBJECTIVE: To identify features of neighborhoods associated with concealed firearm carrying among a representative sample of youth from Chicago, Ill. DESIGN: Cross-sectional analysis of individual- and neighborhood-level data collected by the Project on Human Development in Chicago Neighborhoods. SETTING: Families and neighborhoods in Chicago. PARTICIPANTS: Population-based sample of 1842 multiethnic youth aged 9 to 19 years and the 218 neighborhoods in which they resided.Main Outcome Measure Whether youth had ever carried a concealed firearm. RESULTS: Lifetime estimates for concealed firearm carrying were 4.9% for males and 1.1% for females. We found that youth in safer and less disordered neighborhoods were less likely than youth in unsafe and more disordered neighborhoods to carry concealed firearms. Specifically, multilevel nonlinear regression models identified a positive association between concealed firearm carrying and (1) community members' ratings of neighborhoods as unsafe for children; (2) neighborhood social disorder; and (3) neighborhood physical disorder. Neighborhood collective efficacy was negatively associated with concealed firearm carrying. Models controlled for neighborhood economic indicators and individual and family factors associated with the carrying of concealed firearms by youth. CONCLUSIONS: Youth are less likely to carry concealed firearms in areas where there is less violence and increased safety. Interventions to improve neighborhood conditions such as increasing safety, improving collective efficacy, and reducing social and physical disorder may be efficacious in preventing firearm use and its associated injuries and death among youth.     

Can neighborhoods explain racial/ethnic differences in adolescent inactivity?

OBJECTIVE: To determine if neighborhoods and their attributes contribute to racial/ethnic disparities in adolescent inactivity. METHODS: We undertook a cross-sectional analysis of the National Longitudinal Study of Adolescent Health (n = 17,007), a nationally representative school-based study in the United States. Stratifying by gender, we used multivariate linear regression and multi-level modeling to determine whether neighborhood of residence may partially explain racial/ethnic disparities in adolescent physical inactivity, defined as hours viewing television or videos/DVDs and/or playing computer/video games each week. RESULTS: Participants lived in largely segregated communities. Black and Hispanic adolescent girls reported higher levels of inactivity than White adolescent girls (21 vs. 15 vs. 13 hours/week, respectively, p <0.001). Similar patterns were seen in adolescent boys, with Black adolescent males reporting a mean of 26 hours/week; Hispanic boys a mean of 20 hours/week; and White boys a mean of 17 hours/week of inactivity (p <0.001). After accounting for between-neighborhood variation, there were no residual within-neighborhood differences in inactivity between Hispanic and White adolescent girls (gamma = -0.06, p =0.93); when living in the same neighborhood Hispanic and White girls had similar levels of inactivity. Black adolescent girls and boys were found to have higher levels of inactivity no matter where they lived (gamma =7.00, p <0.001 for girls; gamma = 6.96, p <0.001 for boys). Hispanic boys had similar patterns of inactivity to White boys (gamma =-1.57, p = 0.12). In both males and females, the reported rate of violent crime in the neighborhood was associated with inactivity, despite the individual's perception of his/her neighborhood as safe not being predictive. CONCLUSIONS: Although inactivity varies by race/ethnicity and gender, only in Hispanic adolescent girls does neighborhood fully explain the differential use. Our findings suggest that approaches other than changing neighborhood characteristics are needed to eliminate racial/ethnic disparities in adolescent inactivity.     

Prevalence and correlates of partner violence among South African adolescents

BACKGROUND: Little is known about the prevalence of partner violence among adolescents, nor of the factors with which it is associated. The objectives of this study were to document prevalence rates for partner violence among high school students in Cape Town, and to explore factors that are associated with such violence. METHOD: The sample consisted of 596 Grade 8 and 11 students attending public high schools in Cape Town, who were selected using a multistage cluster design. They completed an anonymous and confidential questionnaire. The dependent variable was whether they had ever perpetrated partner violence, or intended to do so. The independent variables, which were derived from a modified version of the Theory of Planned Behaviour (TPB), included attitudes, subjective norms (general and peer social influence and outcome expectancy) and self-efficacy. Separate multiple logistic regression models were developed of partner violence intentions or behaviours on the scales derived from the TPB and demographic variables. Regression coefficients from adjusted models were used to examine the potential mediating role of partner violence intentions in the association between each scale and partner violence behaviours using the Sobel test. RESULTS: Among participants who reported being in a relationship, 20.7% reported perpetrating partner violence, and 16.4% reported intending to do so. After adjusting for demographic characteristics and other predictor scales, perpetration of partner violence was significantly associated with attitudes and outcome expectancy, while intention to perpetrate partner violence was significantly associated with attitudes and general social influence. The influence of attitude and general social influence on violent behaviours were each partially mediated by partner violence intentions. CONCLUSIONS: There are high levels of partner violence among high school students in Cape Town. Interventions to address this problem should focus on violence-related attitudes and outcome expectancy.     

From antisocial behavior to violence: a model for the amplifying role of coercive joining in adolescent friendships

Background: Aggression is one of the more stable characteristics of child and adolescent development, and violent behavior in early adulthood is often foreshadowed by aggressive behavior in childhood and early adolescence. Considerable evidence has linked coercive family interactions to aggressive behavior in childhood, but less research has been conducted on the joint role of family and peer interaction in the escalation of aggression to violence in adulthood. Methods: We coded family interactions at age 12–13 and friendship interaction at age 16–17 in a multiethnic sample of youth and families. Violence in young adulthood (age 22–23) was measured using self‐report, criminal records, and parent report. We tested the hypothesis that a process of ‘coercive joining’ in friendship interactions mediated the relationship between coercive family interactions and serious violence. Results: We found that observed coercive joining in friendships at age 16–17 predicted early‐adulthood violent behavior over and above an established tendency toward antisocial behavior. We also found that observed coercive family interactions at age 12 predicted early‐adulthood violence, and that coercive joining with friends fully mediated this link. Conclusions: These results significantly extend coercion theory by suggesting that coercive joining in the context of peer groups is an additional mechanism by which coercive processes in the family are extended and amplified to violent behavior in early adulthood. Our findings suggest the importance of addressing both individual interpersonal skills and self‐organizing peer groups when intervening to prevent violent behavior.
