Substance use as a longitudinal predictor of the perpetration of teen dating violence

Longitudinal Trajectories of Physical Teen Dating Perpetration and Trait Anger Expression: A Group-Based Trajectory Approach

Dating violence is often perpetrated among adolescents, which increases the efforts to better understand individual risk factors for preventive efforts. Although multiple forms (i.e., physical and psychological) often coexist, few studies have studied the chronicity and developmental classes of physical teen dating violence and examined whether subtypes of trait anger predict teen dating perpetration over time. Thus, the purpose of the current study is to investigate: (a) the developmental group-based patterns of physical teen dating violence; and (b) whether subtypes of trait anger expression predict association in these classes using the Bullying, Sexual, and Dating Violence Trajectories from Early to Late Adolescence in the Midwestern United States, 2007 to 2013 dataset. Group-based trajectory modeling results identified four classes of teen dating violence perpetration (e.g., Accelerating, Abstaining, Desisting, and High Chronic). Multinomial logistic regression results indicated that expressing anger outwardly was positively associated with Desisting and High Chronic patterns, but not Accelerating patterns. These results suggest that there are four classes of teen dating violence perpetration and underscore the effects of expression of trait anger as a risk factor of teen dating violence perpetration. Practical and theoretical implications are discussed.

Discordant and Concordant Substance Use and Daily Partner Violence in Adolescent and Young Adult Relationships With Baseline Dating Violence

PURPOSE

Intimate partner violence (IPV) and substance use in adolescents and young adults (AYAs) are significant public health issues in the United States. Together, they can harm emotional regulation and romantic relationship functioning. This study examines the role of concordant and discordant substance use on IPV within AYA relationships.

METHODS

A prospective cohort of community-recruited AYA women in a heterosexual dating relationship with past-month IPV completed four months of daily surveys via a cell phone. Each day, participants reported any IPV perpetration and/or victimization, their alcohol and drug use, and observed partner substance use. Concordant substance use was coded when the participant and partner used drugs or alcohol on the same day. Discordant use was coded when only the participant or partner used drugs or alcohol on a given day. Alcohol and drug use were modeled separately. Generalized estimating equations accounted for the correlation of repeated measures.

RESULTS

Participants (N = 143) were 18.2 (1.1) years old, 93% African American race. Discordant alcohol and drug use was associated with same-day victimization, perpetration, and co-occurring violence compared to concordant nonuse. Similarly, concordant alcohol use, drug use, and alcohol/drug use were associated with increased odds of victimization, perpetration, and co-occurring violence compared to concordant nonuse.

DISCUSSION

Daily data illustrated that dyadic patterns of substance use are associated with IPV. These findings may facilitate the development of effective and developmentally appropriate IPV intervention programs for AYA that also integrate strategies to reduce substance use.

Examining the Relation Between Early Violence Exposure and Firearm-Related Experiences in Emerging Adulthood: A Longitudinal Cohort Study

Firearms are a leading cause of death among adolescents and young adults in the United States. Early exposure to violence, as a victim or witness, is associated with increased risk of firearm-related experiences, including carrying and threatening others with a gun. These experiences, in turn, increase the risk of both fatal and non-fatal firearm injuries. Using an ethnically diverse sample of emerging adults, we build on prior research by examining the link between early violence exposure at multiple contexts of the social-ecological model and multiple firearm-related experiences (i.e., firearm-threatening victimization, firearm-threatening perpetration, and firearm carriage). We analyzed data from a 10-year longitudinal study of 1042 youth in the Southern United States. Experiencing childhood physical abuse was associated with both firearm-threatening victimization and perpetration in emerging adulthood. Additionally, exposure to neighborhood and interparental violence were linked to threatening others with firearms and carrying firearms, respectively. Counter to expectations, bullying victimization did not emerge as a predictor of any firearm-related experiences. Findings highlight the importance of cross-cutting violence prevention efforts to prevent high-risk firearm-related behaviors among emerging adults. Programs for children and adolescents that address these types of violence exposure should highlight coping skills and sources of positive social support to bolster protective factors against firearm-related outcomes.

The company you keep: The neglected role of affiliating with delinquent friends in the development of the cannabis-violence link

A growing body of research suggests a potential role of cannabis use on aggressive behaviors. In literature on adolescents, the lack of consideration of important confounders, such as adolescent's affiliation with delinquent peers, limits the possibility to determine whether there might be a direct or indirect link between cannabis use and aggression. Therefore, we sought to examine the effect of delinquent peers on the association between cannabis use and violence. We re-analyzed data from 850 ninth graders who were followed from mid-adolescence to early adulthood. Generalized Estimations Equations (GEE) were conducted to examine whether affiliation with delinquent peers may mediate the relationship between cannabis use and violence. Cross-Lagged Panel Models were also conducted to estimate the directionality of these relationships over time. We additionally tested whether similar relationships may be identifiable when examining rule-breaking behaviors and/or alcohol use. GEE models revealed that both cannabis use and affiliation with delinquent peers were statistically associated with aggressive behaviors. Cannabis use, alcohol use and delinquent peers also predicted rule-breaking behaviors. More precisely, cross-lagged models showed that affiliation with delinquent peers played a partially mediating role in the cannabis-aggression link, and that similar cross-lagged estimates were observed when examining rule-breaking behaviors instead of aggression. Our results indicate that cannabis use may be associated with aggression as well as rule-breaking behaviors, suggesting a broader effect on conduct problems. More importantly, our study highlights the non-negligible role of affiliating with delinquent peers during adolescence.

Firearm access, carriage and use in an ethnically diverse sample of young adults in Texas, USA

Background Despite the high rates of firearm ownership and firearm-related injuries and mortalities in Southern US states, understandings on the factors contributing to these are lacking.Methods Using wave 10 (2021) data from a longitudinal study, we examined firearm-related experiences among 636 ethnically diverse young adults (mean age=26 years; 62% female) in Texas, USA.Results Just over half of participants had ready access to firearms, with 22.3% having carried a firearm outside of their home, 4.9% having been threatened with a firearm by a romantic partner and 4.4% by a non-romantic partner. More firearm access and carriage were reported in males, white participants and those with >US$50 000 income. More females than males had been threatened with a firearm by a romantic partner, but more males than females had been threatened by a non-partner. Participants with recent financial difficulties were proportionally more likely to be threatened with a firearm than those without difficulties.Conclusion Findings emphasise the alarming rate of firearm access and carriage in Texas and highlight the disparities in firearms experiences by sociodemographic characteristics.

Reproductive Coercion and Intimate Partner Violence Perpetration Among Young Adult Males

Reproductive coercion is any behavior that attempts to control the autonomous reproductive decision-making of an intimate partner. Very little research has focused on males who perpetrate reproductive coercion. Using a diverse community sample of young adults, we examined the prevalence of lifetime reproductive coercion perpetration and its relationship with other forms of intimate partner violence (IPV). Results demonstrated that approximately 6.4% of the men reported perpetrating reproductive coercion in their lifetime. Chi-square analyses demonstrated that men who reported sexual (16.2%), physical (11.1%), or psychological (59.1%) IPV perpetration, relative to men who did not, reported a significantly higher prevalence of reproductive coercion perpetration.

Proxies of Emotion Dysregulation and Teen Dating Violence Perpetration: A Latent Profile Analysis

PURPOSE

Teen dating violence (TDV) must be addressed as a public health issue due to its prevalence and association with negative health outcomes among victims. To prevent TDV, it is essential to examine the risk factors of dating violence perpetration's applicability to younger samples. Using a population health approach, this study explored the associations among variables that affect emotion regulation and TDV perpetration of multiple types among a diverse sample of high school students.

METHODS

Latent profile analysis of four self-reported variables related to emotion regulation (anger regulation, depressive symptoms, impulsivity, and alcohol use) was conducted among a sample of 1,508 students. Next, regression analyses were used to test the relation between latent profile membership and self-reported TDV perpetration across two time points.

RESULTS

A three-profile solution was found to be the solution of best fit (profile 1: n = 1,023, profile 2: n = 43, and profile 3: n = 442). Profile one had low means across all indicators; profile two had a high mean of recent alcohol use; and profile three had low to moderate means across all indicators. Profile two was associated with the most frequent lifetime perpetration and perpetration one year later. However, all three profiles were only associated with infrequent perpetration.

DISCUSSION

This study found that an emotional regulatory framework was applicable to assess some risks of TDV. These findings justify further research on the relation between emotion regulation and TDV perpetration; however, risk factors at other socio-ecological levels should be incorporated to strengthen existing theories.

Reproductive Coercion Victimization and Associated Mental Health Outcomes Among Female-Identifying Young Adults

Reproductive coercion is a serious public health problem. Victimization has been associated with poor mental health outcomes, including symptoms of posttraumatic stress disorder (PTSD) and depression in clinical and college samples. We build on these findings by examining the association between reproductive coercion victimization and mental and behavioral health outcomes, including depression, PTSD symptoms, anxiety, and drinking behaviors in a diverse community-derived sample of female-identifying young adults (mean age = 20; SD=.72). Participants (n = 368) were originally recruited as part of a study on dating violence in seven Texas public high schools. Participants completed an online study that included demographic questions and measures that assessed the variables of interest. Results of regression analyses showed that reproductive coercion victimization predicted depression, anxiety, and PTSD symptoms, after controlling for race, sexual orientation, and age. The findings also revealed that victims of reproductive coercion were more likely consume more drinks per drinking occasion compared to their non-victimized counterparts. These results add to the growing literature that experiencing reproductive coercion is a risk marker for poor mental and behavioral health. To develop targeted prevention and intervention programs, future research should examine potential mechanisms underlying this relationship.

Reproductive Coercion and Intimate Partner Violence Victimization Among a Racially and Ethnically Diverse Young Adult Sample

Reproductive coercion is an understudied form of intimate partner violence (IPV) that occurs when a person attempts to control the autonomous reproductive decision making of their intimate partner. Previous research has demonstrated that individuals who experience reproductive coercion are more likely to experience other forms of IPV (e.g., physical and sexual). Research has also shown that Black/African American and Latinx/Hispanic individuals are at an increased risk of experiencing reproductive coercion compared to their White/Non-Hispanic peers. However, most of the research on reproductive coercion has been conducted in family-planning clinics where IPV is reported at a higher rate than in community samples. Thus, using a diverse community sample of female-identifying young adults (N = 370) who were recruited as part of an ongoing longitudinal study on dating violence, we examined the prevalence of lifetime reproductive coercion and its relationship with other forms of IPV, as well as the differences in prevalence among racial and ethnic groups. Lifetime prevalence of being victimized by any form of reproductive coercion was 11.4%. Results indicated that individuals who experienced reproductive coercion were more likely to experience physical and sexual IPV relative to those who did not experience reproductive coercion. With respect to race/ethnicity, 5.6% of White participants, 10.5% of Black/African American participants, and 14.8% of Hispanic/Latinx participants reported experiencing reproductive coercion. Chi-square analyses showed Hispanic/Latinx participants had a significantly higher prevalence of reproductive coercion when compared to White/Non-Hispanic participants. These findings suggest a need for additional research on culturally-specific risk and protective factors related to reproductive coercion among Hispanic/Latinx individuals to identify potential intervention and prevention strategies.

Reported Perpetration of Intimate Partner Violence among Adolescent Girls: Motivations and IPV Victimization

Background: Studies on intimate partner violence (IPV) perpetration by girls and women have found self-defense is a common motivation. Current items—namely the abbreviated items from the Conflicts Tactics Scale (CTS)—used to measure IPV perpetration may be counting these girls/women as perpetrators when they are victims of IPV. The purpose of this study was to assess adolescent girls’ IPV perpetration, including (a) motivations and (b) factors associated with reports of adolescent girls’ perpetration of IPV using standard abbreviated CTS measures. Methods: This study utilized cross-sectional survey data collected from 159 participants in an urban Southern California clinic in 2016–2018. Demographic variables—age, ethnicity, current school enrollment, living situation and born in the U.S.—were analyzed with chi-square or independent t-tests. Frequency analyses were used to quantify motivations for IPV perpetration. Crude and adjusted logistic regression models assessed key variables associated with female adolescents’ IPV perpetration: victimization, drug use, alcohol day, binge drinking, depression, anxiety, and suicide ideation. A final multivariate model further adjusted for IPV victimization. Results: The average age of participants was 17 years old, and the majority of participants were Hispanic. Primary motivations for adolescent girls’ IPV perpetration included self-defense. Adolescent girls who reported IPV perpetration had significantly greater odds of victimization [95% CI = 4.31–32.07], drug use [95% CI = 1.14–6.99], binge drinking [95% CI = 1.08–6.87], and suicide ideation [95% CI = 1.13–10.62]. These findings remained significant in models adjusted for significant demographics. In the final multivariate regression model adjusted for IPV victimization, none of these factors remained significantly related to adolescent girls’ IPV perpetration. Conclusions: Findings establish a connection between victimization, self-defense, and adolescent girls’ IPV perpetration. These findings add to existing literature suggesting that the CTS measures of perpetration may encompass both IPV victimization and perpetration when used with populations of girls and women.

A community‐wide approach to reducing risky drinking cultures in young people in rural Australia

OBJECTIVE

This study evaluated the impact of a multi-faceted, harm minimisation program addressing youth alcohol change and risky drinking behaviours in rural Australia. The role and influence of a multi-tiered community approach to changing alcohol cultures is examined.

SETTING

An alcohol culture change project for young people (12-18 years) was implemented in rural Victoria. It was informed by the Alcohol Cultures Framework, comprising community-wide events and youth-focused activities, co-designed with young people. The approach aimed at maximising engagement and reducing alcohol-related harm by targeting the shared activities and drinking practices of young people, parents and the community.

PARTICIPANTS

Participants (n = 446) provided feedback specific to three key program activities for promoting alcohol change.

DESIGN

Mixed methods: Feedback sheets were collected, and interviews and focus groups were conducted with program participants.

RESULTS

Participants indicated that the program had informed their understanding of the way people in their region drink, and the social norms and practices around alcohol that encourage risky drinking. It influenced their short- and medium-term reactions, learnings and activities relating to alcohol consumption. The impact of the program was greatest in adults than young people although reflective learning and some behaviour change were evident across all age groups and community clusters.

CONCLUSION

Community-wide health promotion events offer participants a deeper understanding of the ways in which dominant alcohol cultures inform the practices and activities of young people within a broader community context. Ensuring health promotion programs within a whole-of-community approach are established longer term, is recommended.

Peer sexual harassment, affect, and substance use: Daily level associations among adolescents

INTRODUCTION

Peer sexual harassment is associated with adolescent substance use at the global level; however, it is unknown whether substance use occurs proximal in time to the sexual harassment experience. This study used daily reports to examine the proximal relations between sexual harassment victimization and affect and substance use. Based on theories of self-medication, we hypothesized that negative affect and substance use (cigarettes, electronic cigarettes, alcohol, and marijuana) would be higher than typical on days when sexual harassment occurred relative to nonvictimization days.

METHOD

A community sample of 13-16-year-old adolescents (N = 204, 55.4% female) from a metropolitan area in the northeastern United States completed 56 days of online reports assessing experiences with peer sexual harassment, substance use (cigarettes, electronic cigarettes, alcohol, and marijuana), and positive and negative affect.

RESULTS

Multilevel modeling revealed that experiencing sexual harassment on a given day was associated with higher than typical negative affect on that day, relative to nonvictimization days. The likelihood of cigarette and alcohol use (but not electronic cigarettes, marijuana, or positive affect) was greater on days when sexual harassment occurred.

CONCLUSION

Sexual harassment victimization is proximally associated with negative affect and alcohol and cigarette use, suggesting that adolescents may be using substances to cope with sexual harassment victimization. The co-occurrence of sexual harassment with negative affect and substance use points to the need for prevention efforts that conjointly address sexual harassment victimization, coping, and substance use.

Analysis of Representations of the Aid That Public Psychological Support Points Provide to Adolescent Female Victims of Gender-Based Violence: Reformulation of Policies and Practices

Gender-based violence in adolescence has become a social health problem that is creating great concern and interest worldwide. In this regard, knowledge of the role taken by the professionals responsible for screening, detecting, referring, and caring for adolescent victims is essential to be able to understand the phenomenon and its characteristics in a practical way. In this sense, psychologists specialising in the care of victims of adolescent gender-based violence have complete and in-depth knowledge, not only of the phenomenon itself and the way in which it is presented in society, but also of the features presented by these victims and the aspects that need to be worked on during the intervention process. Given this context, a series of interviews with psychologists specialised in the care of gender-based violence victims were subjected to a qualitative deductive/inductive analysis. These interviews addressed the psychologists' theoretical-practical knowledge about the adolescent gender-based violence phenomenon. The analysis of the results points to the victims' irrational ideas regarding abusive relationships, to the form in which Psychological Support Points are organised to help the victims, and to the strengths, weaknesses, and needs of these centres for them to be able to improve their operation and effectiveness in providing comprehensive care for adolescents beyond the psychological consultations themselves.

Predictors of Sexual Intimate Partner Violence Perpetration Among Men: A Prospective Analysis

Research demonstrates that both peer socialization and underage drinking play a significant role in teen dating violence. However, less is known about the lasting effects of these risk factors on boys' ability to form healthy romantic relationships as they get older. The present study examined whether boys who perceived their peers would respect them more for having sex and those who engaged in past year heavy alcohol use would be more likely to perpetrate sexual intimate partner violence (IPV) in young adulthood compared to boys who did not endorse perceived peer approval for sex or report past year heavy drinking. Analyses were conducted using a sample of boys (n = 1,189) from Waves I and III of the National Longitudinal Study of Adolescent to Adult Health (Add Health). A logistic regression was conducted to assess the relationship between perceived peer approval to have sex and heavy alcohol use at Wave I and sexual IPV at Wave III, after adjusting for demographic factors and other correlates of sexual IPV at Wave I, including age, race/ethnicity, sexual initiation in adolescence, parental attachment, annual family income, and neighborhood poverty. Boys who believed they would gain peer respect by having sex and boys who reported getting drunk in the last 12 months, regardless of how often, were significantly more likely to report sexual IPV in young adulthood compared to boys who did not endorse either of these factors. Targeting boys' perceived peer norms regarding sexual activity and heavy alcohol use may therefore be especially important for preventing sexual IPV later in life.

Directionality of Dating Violence Among High School Youth: Rates and Correlates by Gender and Sexual Orientation

Sexual minority adolescents are at greater risk for experiencing teen dating violence (TDV) in their dating relationships. Although adolescents in dating relationships often report experiencing and perpetrating various forms of TDV, the directionality of TDV based on youth's reported gender and sexual orientation is not known. A sample of 10th-grade students (N = 1,622) recruited from high schools in the Northeastern United States completed assessments of TDV victimization and perpetration and reported their past-month heavy alcohol use and marijuana use. Sexual minority girls (58%) and boys (36%) were more likely to experience TDV than heterosexual girls (38%) and boys (25%), respectively. Sexual minority boys were less likely, although the confidence intervals included one, to engage in dual-role physical TDV (odds ratio [OR] = 0.14, 95% confidence interval [CI] [0.00, 1.26]) and threatening TDV (OR = 0.14, 95% CI [0.00, 1.02]), and instead were more likely to be victimized. In contrast, the profiles of TDV were similar for girls, with sexual minority girls only being more likely than heterosexual girls to report dual-role physical TDV (OR = 2.23, 95% CI [1.07, 4.66]). Compared with unidirectional TDV, bidirectional TDV was significantly associated with sexual minority girls' substance use, but not with heterosexual girls' substance use. Sexual minority youth report higher rates of TDV, with sexual minority boys being distinctly at-risk for being victimized within their dating relationships. Engagement in both TDV victimization and perpetration was distinctly associated with substance use for sexual minority girls, highlighting the need for integrated prevention efforts and support.

Polydrug Use and Dating Violence Among Emerging Adults

We examined sociodemographic and psychosocial risk factors that moderate the (poly) substance use and dating violence victimization and perpetration relationship among emerging adults. Using an ethnically diverse sample (N = 698), we used latent class analyses to identify mutually exclusive groups based on monthly and past-year substance use. We then examined these groups as they relate to dating violence victimization and perpetration and the moderating effect of various risk factors. Five classes were identified based on substance use patterns: (a) Regular Alcohol use, (b) Polysubstance use, (c) Heavy Alcohol and Marijuana use, (d) Mild Alcohol use, and (e) Occasional Alcohol and Marijuana use classes. Participants in the Polysubstance use class were the most likely to perpetrate dating violence followed by Heavy Alcohol and Marijuana use, Occasional Alcohol and Marijuana use, Regular Alcohol, and Mild Alcohol use classes. Similarly, participants in the Polysubstance use class were the most likely to be victims of dating violence followed by Occasional Alcohol and Marijuana, Heavy Alcohol and Marijuana, Regular Alcohol, and Mild Alcohol use classes. Depending on substance use class, gender, ethnicity, socioeconomic status, history of dating violence, and trauma symptoms differentially influenced dating violence perpetration and victimization at 1-year follow-up. Our findings support the need to comprehensively address dating violence among emerging adults. Intimate partner violence prevention and intervention programs may benefit from targeting emerging adults who misuse substances and incorporating substance use interventions into dating violence prevention efforts.

Supplementing Substance Use Prevention With Sexual Health Education: A Partner-Informed Approach to Intervention Development

Supplementing substance use prevention with sexual health education would allow educators to address the risk and protective factors that influence both health issues. This streamlined approach may minimize the inefficiencies of multisession, single-purpose interventions. Our team developed a supplemental sexual and reproductive health (SRH) unit to align with an existing evidence-based intervention, LifeSkills Training (LST). This goal of this article is to describe our process, final product, lessons learned, and future directions. Our partner-informed approach took place across three key phases: (1) formative insights, (2) unit development, and (3) pilot implementation. The final supplemental SRH unit is ten, 45-minute sessions offered to seventh- and eighth-grade students and includes a set of learning objectives that are aligned with individual sessions. The supplemental SRH unit also mirrors existing LST modules in length, flow, layout, facilitator instructions, focus on prevention, and utilization of a student workbook. Lessons learned include strategies to effectively incorporate a wide range of ongoing feedback from multiple sources and quickly respond to staff turnover. This partnership approach serves as a model for researchers and practitioners aiming to extend the reach of existing evidence-based programs.

Informal and Formal Mentoring of Sexual and Gender Minority Youth: A Systematic Review

Research demonstrates that mentoring relationships can promote positive outcomes for youth across numerous domains, a topic of importance to school social workers. Whereas most mentoring research to date has been conducted with heterosexual cisgender youth, there is a growing body of literature that examines mentoring experiences among sexual and gender minority youth (SGMY). The purpose of this article is to conduct a systematic literature review of informal and formal mentoring experiences among SGMY. Results from twelve studies that met inclusion criteria suggested that (1) the majority of SGMY report having a mentor/role model; (2) demographics are generally unrelated to having a mentor; (3) SGMY seek out mentors with certain characteristics; (4) mentors promote positive outcomes across psychosocial, behavioral, and academic domains; and (5) mentors report varying levels of self-efficacy in mentoring SGMY and disparate motivations for becoming a mentor. Several limitations of the extant literature were identified, underscoring the need for methodologically rigorous and more inclusive research. Nevertheless, preliminary research suggests that SGMY benefit from having a mentor and that efforts are needed to safely connect SGMY to high-quality informal or formal mentors.

In-Person and Cyber Dating Abuse: A Longitudinal Investigation

While studies have identified associations between cyber and in-person dating abuse, most research has relied on cross-sectional data, limiting the ability to determine temporality. This study tested the longitudinal associations between cyber and physical and psychological forms of in-person dating abuse. Data were from an ongoing longitudinal study following a group of high school students originally recruited in Southeast Texas, U.S., into their young adulthood. Three waves of data (Waves 4-6) were used, with each wave collected one year apart. At Wave 4, participants' age ranged from 16 years to 20 years (Mean = 18.1 years, Median = 18.0 years, SD = .78). The analytical sample consisted of 879 adolescents/young adults (59% female, 41% male; 32% Hispanics, 28% Black, 29% White, and 11% other) who completed the dating abuse questions. Cross-lagged panel analysis showed that dating abuse victimization and perpetration were predictive of subsequent dating abuse of the same type. Cyber dating abuse perpetration was found to predict subsequent physical dating abuse perpetration as well as physical dating abuse victimization, but not vice versa. Further, cyber dating abuse perpetration predicted psychological dating abuse victimization, but not vice versa. Cyber dating abuse victimization was not significantly associated with either physical or psychological dating abuse temporally. Overall, findings suggest that cyber dating abuse perpetration may be a risk marker for both physical and psychological forms of in-person dating abuse. Interventions may benefit from targeting cyber dating abuse perpetration as means to prevent in-person dating abuse.

A Dating Violence Prevention Program for Middle School Youth: A Cluster Randomized Trial

OBJECTIVES

We conducted a cluster randomized controlled trial to test the a priori hypothesis that students attending an intervention middle school would be less likely to report physical adolescent relationship abuse (ARA) 1 year later compared with students attending a control school. Secondary objectives were to determine if the intervention reduced substance misuse, bullying, and fighting.

METHODS

Twenty-four Texas public middle schools were matched by the size of student enrollment, number of economically disadvantaged students, and race and ethnicity of the student body and randomly assigned to the intervention (n = 12; 1237 participants) or the control (n = 12; 1531participants) group. The intervention, Fourth R, is a classroom-based curriculum delivered by existing teachers and consists of 21 lessons on injury prevention, substance use, and growth and development.

RESULTS

Participants (50% female) self-reported ethnicity as Hispanic or Latinx (35%), Black or African American (24%), Asian American (17%), White (8%), and multiethnicity or other (16%). Among those who have dated, students in the intervention schools were less likely to report perpetrating physical ARA (intervention = 14.9% versus control = 18.3%) relative to students in the control schools (adjusted odds ratio, 0.66; 95% confidence interval, 0.43-1.00; P = .05). In the overall sample, no significant differences emerged between control and intervention groups with respect to substance misuse, fighting, and bullying.

CONCLUSIONS

The middle school version of Fourth R is effective in reducing physical ARA perpetration over at least 1 year. The intervention did not have an effect on bullying perpetration, physical fighting with peers, and substance misuse. Long-term assessment, especially follow-up that covers the transition to high school, is needed to examine the program benefit on key outcomes.

Determinants of Intimate Partner Violence Among Young Men Who Have Sex With Men: The P18 Cohort Study

Intimate Partner Violence (IPV) is an understudied health problem among young gay, bisexual, and other non-identified young men who have sex with men (YMSM). According to cross-sectional studies, IPV is associated with psychosocial and mental health problems, such as stigma and depression, among YMSM. IPV is also associated with health-risk behaviors, such as substance use, among this population. Yet, to date, no studies have used longitudinal data to examine determinants of IPV among YMSM. This gap in the extant literature is problematic, as it limits our understanding of how to intervene to interrupt cycles of violence. The aim of the present study was to examine longitudinal determinants of IPV among a sample of (N = 526) YMSM living in the New York City area. Longitudinal analyses using Generalized Estimating Equations (GEE) were used to examine individual, relationship, mental health, psychosocial, and substance use factors in relation to IPV victimization and perpetration. Most notably, early experiences of IPV were a robust predictor of later experiences of IPV victimization and perpetration. Relationship status, depression, public gay-related stigma, and illicit substance use were associated with IPV victimization over time. Similarly, relationship status, depression, public gay-related stigma, marijuana, and other illicit substance were associated with IPV perpetration. These findings suggest that prevention programs and awareness campaigns should aim to reach YMSM before their first experiences of relationship violence, as these early experiences of violence are strongly linked to later experiences of violence. Also, IPV interventions should be tailored to the needs of YMSM and should target depressive symptoms, gay-related stigma, and substance use behaviors. Additionally, substance use interventions may be improved by addressing IPV. Finally, policymakers should support policies that improve the social climate for LGBTQ people, thereby reducing gay-related stigma, and potentially stemming violence against and among YMSM.

Association of Addictive Substance Use with Polyvictimization and Acceptance of Violence in Adolescent Couples

Theoretical framework: The objectives of this study were to analyse the possible influence that some variables such as substance use (alcohol and marijuana) might have on relevant aspects related to violence in adolescent dating (victimization, frequency of violence and acceptance of violence). Methods: The sample included 2577 adolescents between the ages of 14 and 18. The instruments used were two questionnaires. The first identified and analysed the types and frequency of violence experienced by the victims, and their acceptance of violence. The second analysed the use of alcohol and marijuana in adolescents. Results: The results indicate that victims frequently take on the role of polyvictims, suffering aggression in up to more than five different forms at the same time. Furthermore, it was found that this phenomenon is precipitated by substance use, the frequency of abuse and the acceptance of violence in a cycle of mutual interaction.

Risk Markers for Physical Teen Dating Violence Perpetration: A Meta-Analysis

Teen dating violence (TDV) is a common problem among adolescents and has been linked to various negative outcomes. This study used Dutton's nested ecological theory to examine risk markers for physical TDV perpetration and examine whether there are significant differences in the strength of risk markers between male and female adolescents. This meta-analysis included 37 studies yielding 126 unique effect sizes for risk markers for physical TDV perpetration in samples from the United States. In the microsystem level, a total of 14 risk markers were examined and in the ontogenetic level, 12 risk markers were examined. Our results revealed that, in the microsystem, physical TDV victimization was the strongest risk marker for physical TDV perpetration. On the ontogenetic level, externalizing behaviors, approval of violence, risky sexual behaviors, alcohol use, depression, and delinquency were the strongest risk markers for TDV perpetration. Conflict resolution skills and responsibility were protective markers against TDV perpetration. When comparing the strength of risk markers between males and females, we found that undifferentiated TDV perpetration and depression were significantly stronger risk markers for female perpetration than male perpetration. We also found that exhibiting controlling behaviors was a significantly stronger risk marker for male TDV perpetration than female TDV perpetration. These findings highlight the importance of the microsystem, specifically the dating relationship itself, when identifying adolescents at risk for TDV perpetration.

The Association Between PTSD Symptoms and IPV Perpetration Across 6 Years

A large literature documents that posttraumatic stress disorder (PTSD) symptoms are associated with intimate partner violence (IPV) perpetration among adults. However, research on this relationship among adolescents and young adults has been plagued by methodological flaws (e.g., cross-sectional designs). Thus, the purpose of the present study was to examine the longitudinal and bidirectional associations between PTSD symptoms and psychological and physical IPV perpetration from adolesence to young adulthood. A sample of racially and ethnically diverse high school students (N = 1,042; 56% female) were assessed annually for 6 years (from 2010 to 2015 in Southeastern Texas). At each assessment, participants completed measures of PTSD symptoms and psychological and physical IPV perpetration. The mean age of the sample at the first assessment was 15.09 (SD = .79). Structural equation modeling demonstrated that PTSD symptoms at Years 2, 3, and 4 predicted increases in psychological IPV perpetration in the subsequent year. In turn, psychological IPV perpetration at Years 1 and 4 predicted increases in PTSD symptoms in the subsequent years. In addition, psychological IPV perpetration mediated the association between PTSD symptoms and physical IPV perpetration over time. Results were consistent across gender and race/ethnicity. Findings provide initial evidence that PTSD symptoms are associated with IPV perpetration across time from adolescence to young adulthood. Prevention and intervention programs for adolescent and young adult IPV perpetration may benefit from screening for, and potentially treating, PTSD symptoms.

Substance Use and Disparities in Teen Dating Violence Victimization by Sexual Identity Among High School Students

Sexual minority youth (SMY) report more substance use and experience more physical and sexual dating violence victimization than heterosexual youth; however, few studies have explored the relationship between substance use and disparities in teen dating violence and victimization (TDVV) using national-level estimates, and examined if these relationships vary by sexual minority subgroups. Data from the nationally representative 2015 and 2017 national Youth Risk Behavior Surveys were used to examine differences in TDVV and substance use by sexual identity, and to determine if substance use was associated with TDVV disparities between SMY and heterosexual high school students who dated 12 months prior to the survey (n = 18,704). Sex-stratified logistic regression models generated prevalence ratios adjusted for demographic characteristics and substance use behaviors to determine if substance use mediated the relationship between sexual identity and TDVV. Compared with their heterosexual peers, SMY experienced higher rates of TDVV and were more likely to report using most types of substances, although differences were more pronounced among female students compared with male students. Disparities in TDVV were reduced for male gay and bisexual students as well as for female bisexual students once substance use was entered into the model, suggesting that there is a relationship between substance use and some of gay and bisexual students' risk for experiences of TDVV. Comprehensive efforts for violence prevention among sexual minority students may benefit from incorporating substance use prevention, given its relationship to disparities in TDVV.

Sexual Dating Violence, School-Based Violence, and Risky Behaviors Among U.S. High School Students

Sexual dating violence is associated with several risky health behaviors among adolescents. This study explored the associations between school-based violence, risky health behaviors, and sexual dating violence victimization among U.S. high school students using the 2017 Youth Behavior Risk Survey data. Results indicate a statistically significant correlation (p < .05) between sexual dating violence, sex, sexual identity, and various risky behaviors including bullying, electronic bullying, alcohol use, and physical fighting. These additional behavioral risks experienced by sexual dating violence victims should be further researched to determine impact on overall quality of life and to help guide health education intervention development.

Adolescent and Young Women's Daily Reports of Emotional Context and Episodes of Dating Violence

PURPOSE

To investigate same day, previous day, and next day associations between trust, closeness, commitment, jealousy and provision of instrumental support with dating violence victimization and perpetration.

METHOD

A convenience sample of young women, 16-19 years, in a heterosexual dating relationship with at least one act (past month) of physical or psychological victimization or perpetration, were recruited from urban public locations. Participants answered questions daily via text continuously for four months on dating violence and partner-specific emotions. Daily surveys asked about trust, closeness, commitment for their partner, jealousy, perceptions of partner's jealousy and provision of instrumental support to and from partner, and dating violence victimization and perpetration. Multilevel modeling examined within-relationship associations over time.

RESULTS

Mean (sd) age for the full sample was 18.1 (1.1) years. Same-day emotional context (trust, closeness, commitment, jealousy and provision of instrumental support) was more strongly associated with victimization and perpetration compared to previous day emotions. Strongest same-day positive associations were with partner's perpetration, both partner's jealousy, and females' instrumental support. Partner's jealousy and increased trust were best predictors of next day victimization. Closeness, commitment and trust went down on the day of violence. Perpetration was positively associated with next day commitment. Victimization was positively associated with next day trust.

CONCLUSIONS

This event-level analysis demonstrates the role and timing that emotional aspects of adolescent relationships - including positive feelings - have surrounding episodes of dating violence. This granular understanding of the emotional context of dating violence has the potential to facilitate development of effective, developmentally appropriate interventions.

Exploration of Dating Violence and Related Attitudes Among Adolescents and Emerging Adults

Young people's romantic relationships can be marked with various forms of dating violence (DV). However, adolescents and emerging adults do not necessarily acknowledge this violence because of their attitudes toward dating violence. Our study aims to study dating violence and attitudes toward this phenomenon through two well-established questionnaires administered jointly in their entirety. Indeed, too many studies report results on some dimensions and items, neglecting the richness of available tools. The Conflict in Adolescent Dating Relationship Inventory and the Attitudes Toward Dating Violence Scale were self-administered to 1,014 participants (M age = 18.9) attending secondary schools or a regional college. They reported the frequency of their dating violence perpetration and victimization, and their attitudes toward dating violence. Results show that relational and sexual violence perpetration rates are higher for males, physical violence perpetration rate is higher for females, and relational violence victimization is higher for males. MANCOVAs not only show the same trends for scores but also underline more frequent emotional violence perpetrated by females, physical victimization for males, and sexual victimization for females. Males show higher tolerance toward every form of dating violence; younger participants are also more tolerant. Participants are more tolerant toward male-perpetrated psychological DV than female-perpetrated ones, and more tolerant toward female-perpetrated physical and sexual DV compared with male-perpetrated physical and sexual DV. There are patterns of multiperpetration, multivictimization, bidirectionality, and multi(in)tolerance. Our paper contributes to the symmetry debate, a better understanding of the link between attitudes and violent behaviors, a further step on gendered attitudes regarding who perpetrates and who sustains.

Risk Behaviours Associated with Dating and Relationship Violence among 11-16 Year Olds in Wales: Results from the 2019 Student Health and Wellbeing Survey

(1) Background: This study examines the associations between risk behaviours and adolescent emotional and physical dating and relationship violence (DRV) victimisation and perpetration, and how these vary by gender. The risk behaviours explored include bullying, cyberbullying, sexting, alcohol, and cannabis use; (2) Methods: Cross-sectional self-report data from the School Health Research Network (SHRN) 2019 Student Health Wellbeing (SHW) survey of 48,397 students aged 11–16 from 149 schools across Wales were analysed using single and multiple-behaviour logistic regression models to explore the associations between each risk behaviour and emotional and physical DRV victimisation and perpetration; (3) Results: Bivariate analyses revealed a statistically significant association between DRV and all risk behaviours. In multivariate analyses, students who reported bullying, cyberbullying, sexting, and substance use, compared to those that had not, had significantly higher odds of experiencing and perpetrating emotional and physical DRV; and (4) Conclusions: Future studies on DRV should consider a mixed-methods approach to explore the context in which DRV and risk behaviours interrelate. Results from this study indicate the possibility that prevention and intervention programmes in school settings that seek to develop healthy school environments and peer-to-peer relationships, could inadvertently reduce the occurrence of future DRV and associated risk behaviours.

Mediating Factors Explaining the Association Between Sexual Minority Status and Dating Violence

Dating violence presents a serious threat for individual health and well-being. A growing body of literature suggests that starting in adolescence, individuals with sexual minority identities (e.g., individuals who identify as gay, lesbian, or bisexual) may be at an increased risk for dating violence compared with heterosexuals. Research has not, however, identified the mechanisms that explain this vulnerability. Using a diverse sample of young adults (n = 2,474), the current study explored how minority stress theory, revictimization theory, sex of sexual partners, and risky sexual behavior explained differences in dating violence between sexual minority and heterosexual young adults. Initial analyses suggested higher rates of dating violence among individuals who identified as bisexual, and individuals who identified as gay or lesbian when compared with heterosexuals, and further found that these associations failed to differ across gender. When mediating and control variables were included in the analyses, however, the association between both sexual minority identities and higher levels of dating violence became nonsignificant. Of particular interest was the role of discrimination, which mediated the association between bisexual identity and dating violence. Other factors, including sex and number of sexual partners, alcohol use, and childhood maltreatment, were associated with higher rates of dating violence but did not significantly explain vulnerability among sexual minority individuals compared with their heterosexual peers. These findings suggest the importance of minority stress theory in explaining vulnerability to dating violence victimization among bisexuals in particular, and generally support the importance of sexual-minority specific variables in understanding risk for dating violence within this vulnerable population.

The Role of ADHD in Predicting the Development of Violent Behavior Among Juvenile Offenders: Participation Versus Frequency

Past research has identified attention-deficit/hyperactivity disorder (ADHD) as a risk factor for engagement in violent offending. Despite the link between the disorder and violent offending, this risk factor has yet to be examined as a predictor of heterogeneity in the development of violent offending among juvenile offenders. It is likely that the impulsivity, genetic link, and generally chronic disorder course which are characteristics of the disorder play roles in predicting violent offending, which is consistent with both self-control theory and general developmental theory related to early life deficits and life-course persistent offending. Past research has also elucidated a developmental trajectory model of violent offending, which is utilized by the present research. The present research examines ADHD as a risk factor predicting trajectory group assignment. The Pathways to Desistance data followed 1,354 juvenile offenders for 84 months following conviction for a serious offense. Using multinomial logistic regression, this study extends past research on the development of violent offending among juvenile offenders by examining ADHD as a risk factor predicting assignment to violent offending trajectory groups. Results indicate that meeting criteria for ADHD at baseline predicted membership to all trajectory groups relative to the Abstaining group when all covariates were included. This increase in risk is highest for the trajectory group characterized by the highest frequency of violent offending. This indicates the relevance of identifying and treating ADHD among juvenile offenders to best mitigate risk of violent recidivism throughout adolescence and early adulthood.

Prevalence, Gender and Age Differences of Dating Aggression Among Italian Adolescents

The present study represents an effort to expand and deepen the scant literature on Adolescent Dating Aggression (ADA) within the Italian context; adolescent dating aggression is a public health issue of interest due to its increasing frequency among adolescents. The prevalence of verbal-emotional and physical ADA was examined as well as gender and age differences in a sample of Italian adolescents. Participants included 436 adolescents (47.7% males; 52.3% females) living in northern Italy, aged 16 to 18 years (M = 17.11). Participants completed the Conflict in Adolescent Dating Relationships Inventory measuring abusive behaviors between adolescent dating partners. Non-parametric analyses were computed. Verbal-emotional ADA perpetration and victimization were much more common than physical ADA perpetration and victimization. Females reported higher levels of verbal-emotional and physical ADA perpetration than males. To fully investigate gender differences single behaviors were analyzed and described. Finally, age differences emerged only for perpetrated verbal-emotional abuse with such aggression being highest at age 18. This research suggests that in order to prevent the onset of dating aggression in teens in northern Italy, prevention programs may need to begin earlier than previously provided in junior high school. Another core conclusion is that physical aggression against partners is a problem for both males and females, thus intervention for the empowerment of interpersonal skills are needed.

Association between dating violence and personality type in Mexican university students

Violence against women is a global health problem. Some pathological personality traits have been associated with violence. However, the relation between personality type and dating violence, especially in Mexican students, is not fully known. Therefore, the aim of this study is to evaluate the relation between personality type and dating violence in female university students of the State of Mexico, Mexico. Cross-sectional study conducted from February to September 2019 at a private university in the State of Mexico, Mexico. Female students of the bachelor’s degrees in the field of health sciences were included. Socio-demographic data, dating violence, and personality type were evaluated through questionnaires. Adjusted logistic regression models were applied, using STATA v.13. Students with an extroverted personality were 2.45 more likely to suffer dating violence (95% CI 1.29 to 4.63), adjusted for covariates. Those who reported childhood abuse (OR = 2.33, 95% CI 1.08 to 5.01) and whom their partners had a history of drug use (OR = 2.78, 95% CI 1.17 to 6.60) or who currently use drugs (OR = 4.85, 95% CI 0.92 to 25.7), were more likely to suffer dating violence, adjusted for covariates. Students with extroverted personality were more likely to experience dating violence, compared to those with introverted personality. The results show the need to produce further research to identify specific traits within extroverted female population which makes them vulnerable to dating violence.

Adolescent romantic relationships as a tug of war: The interplay of power imbalance and relationship duration in adolescent dating aggression

The present study investigates the link between power imbalance within the romantic couple and psychological, relational and physical adolescent dating aggression (ADA) perpetration, considering also the role of relationship duration as an indicator of the developmental stage of the relationship. This is the first investigation into whom is perceived to have power in the relationship (the partner or the subject him/herself) by distinguishing between male and female adolescents. Participants were 805 Italian adolescents (36.1% males; 63.9% females) aged 14-20 years (M_age  = 17.16 years, SD_age  = 1.34), all reporting having been in a romantic relationship currently or within the past 6 months. Males perceiving a balanced relationship reported lower levels of psychological ADA perpetration, and they perpetrated more relational ADA in longer relationships where the partner is perceived to have the power. No significant findings emerged regarding physical ADA. Females perceiving themselves as having the power in the relationship reported higher levels of psychological and physical ADA perpetration. They perpetrated more relational ADA when they perceived the partner as having the power in the relationship. Also, females in longer relationships in which power was not perceived as equally shared between partners reported higher physical ADA perpetration. Finally, for both males and females, longer relationships were characterized by higher levels of ADA toward the partner. Findings highlight the importance of studying the interplay between power imbalance and relationship duration on ADA perpetration, and provide the way to understand possible functions of ADA within a romantic relationship.

Socio-ecological determinants of alcohol, tobacco, and drug use behavior of adolescents in Kilifi County at the Kenyan coast

Alcohol, tobacco, and other drug use form a risk factor for health and social problems during adolescence. From a socio-ecological model, perceptions of 85 young people and 10 stakeholders on the types of alcohol, tobacco, and other drugs used and the predisposing and protective factors were explored; among adolescents at the Kenyan Coast in the Kilifi County. We found that the consumption of home-brewed alcohol, tobacco and marijuana smoking, and khat chewing was common and requires multi-component and community-centered intervention. Countering alcohol, tobacco, and other drug use needs enforcement of strong measures to regulate access to alcohol, tobacco, and other drugs for minors; addressing social and cultural norms; strategies for poverty alleviation; and community empowerment.

Gender's Role in Exposure to Interparental Violence, Acceptance of Violence, Self-Efficacy, and Physical Teen Dating Violence Among Quebec Adolescents

Despite efforts to prevent physical teen dating violence, it remains a major public health issue with multiple negative consequences. This study aims to investigate gender differences in the relationships between exposure to interparental violence (mother-to-father violence, father-to-mother violence), acceptance of dating violence (perpetrated by boys, perpetrated by girls), and self-efficacy to disclose teen dating violence. Data were drawn from Waves 1 and 2 of the Quebec Youth Romantic Relationships Project, conducted with a representative sample of Quebec high school students. Analyses were conducted on a subsample of 2,564 teenagers who had been in a dating relationship in the past 6 months (63.8% girls, mean age of 15.3 years). Path analyses were conducted to investigate the links among exposure to interparental violence, acceptance of violence, self-efficacy to disclose teen dating violence (measured at Wave 1), and physical teen dating violence (measured at Wave 2). General exposure to interparental violence was linked, through acceptance of girl-perpetrated violence, to victimization among both genders and to girls' perpetration of physical teen dating violence. No significant difference was identified in the impact of the gender of the perpetrating parent when considering exposure to interparental violence. Self-efficacy to disclose personal experiences of violence was not linked to exposure to interparental violence or to experiences of physical teen dating violence. The findings support the intergenerational transmission of violence. Moreover, the findings underline the importance of targeting acceptance of violence, especially girl-perpetrated violence, in prevention programs and of intervening with children and adolescents who have witnessed interparental violence.

Co-occurrence of Dating Violence Victimization Subtypes: Assessing the Influence of Family Factors, Dating Attitudes, Risky Behaviors, and the Moderating Effect of Gender Among School-Aged Teens

Using data from a nationally representative sample of school-aged teens (n = 795), this study examined covariates associated with three subtypes of dating violence victimization (physical violence, emotional abuse, and imposed isolation). We asked the research questions: What were the family factors, dating attitudes, and risky behaviors associated with three subtypes of dating violence victimization across two time points? Second, were these relationships moderated by gender? Overall, we found widespread co-occurrence of victimization. Contrary to our predictions, not all earlier experiences with dating violence victimization worsened or persisted overtime. Regarding family factors, we did not find substantial statistically significant effects on victimization, with the exception that greater openness with parents was associated with increased occurrence of emotional abuse at Wave 1. In terms of dating attitudes, we found that when respondents condoned violence against a girlfriend, they were more likely to experience physical violence victimization at both waves. Respondents who believed that it is okay to use violence to control a boyfriend's behavior were more likely to report emotional abuse at Wave 1. Similarly, respondents who believed that it is okay to date more than one person, as well as those who condoned sexual intercourse outside of a romantic relationship, were more susceptible to emotional abuse. Regarding risky behaviors, we found that the respondents' victimization experience did not increase with a greater sexual partner acquisition; rather, it exerted the opposite effect on their experience with physical violence victimization. These risky behaviors, however, were only statistically significant at Wave 1. Finally, the moderating effect of gender is noted in the study. Implications from the study are discussed.

Association Between the Use of Cannabis and Physical Violence in Youths: A Meta-Analytical Investigation

OBJECTIVE

The aim of this meta-analysis was to investigate the extent to which cannabis use among youths is associated with the risk of perpetrating physical violence.

METHODS

Searches were conducted in PubMed, PsycINFO, Web of Science, and Google Scholar for articles published from the inception of each database to July 2019. All studies that examined both cannabis use and the perpetration of physical violence in a sample of youths and young adults <30 years old were included. The meta-analysis was performed with a random-effects model. Risk of publication bias was assessed with Egger's test. Guidelines from the Meta-Analysis of Observational Studies in Epidemiology were followed.

RESULTS

After screening 11,348 potential studies, 30 study arms were included, yielding a total of 296,815 adolescents and young adults. The odds ratio for the pooled studies was 2.11 (95% CI=1.64, 2.72). The pooled odds ratios were 2.15 (95% CI=1.58, 2.94) and 2.02 (95% CI=1.26, 3.23) for the cross-sectional and longitudinal studies, respectively. Preliminary evidence suggests that the risk of violence was higher for persistent heavy users (odds ratio=2.81, 95% CI=1.68, 4.74) compared with past-year users (odds ratio=2.05, 95% CI=1.5, 2.8) and lifetime users (odds ratio=1.94, 95% CI=1.29, 2.93). The odds ratio for unadjusted studies was 2.62 (95% CI=1.89, 3.62), and for studies using odds ratios adjusted for potential confounding factors, 2.01 (95% CI=1.57, 2.56).

CONCLUSIONS

These results demonstrate a moderate association between cannabis use and physical violence, which remained significant regardless of study design and adjustment for confounding factors (i.e., socioeconomic factors, other substance use). Cannabis use in this population is a risk factor for violence.

Prevalence of teen dating violence and the associations with substance use and externalizing behaviors in Nicaraguan early adolescents

Purpose

Despite being a significant public health problem, teen dating violence and related risk behaviors are yet to be examined in Nicaragua. This study aims to examine the prevalence of in-person dating violence and cyber dating abuse and to test the associations between teen dating violence and substance use (i.e. alcohol, cigarette, marijuana and e-cigarette) as well as externalizing behaviors.

Design/methodology/approach

Survey responses were collected from a school-based sample of 1,799 Nicaraguan early adolescents (average age = 13.04 years).

Findings

The prevalence was 41% for in-person dating violence victimization, 39% for in-person dating violence perpetration, 30% for cyber dating abuse victimization and 26% for cyber dating abuse perpetration. The majority (56%) of the adolescents reported engagement in externalizing behaviors, but substance use prevalence was relatively low, ranging from 1–9% depending on the substance type. Multivariate regression analyses suggest that in-person dating violence perpetration was positively associated with all types of substance use and externalizing behaviors, while victimization was only associated with externalizing behaviors.

Originality/value

Despite the descriptive nature, the study is the first to examine the prevalence of teen dating violence and its relationships with other risk behaviors in Nicaraguan adolescents and have important health implications.

Longitudinal analysis of alcohol use and intimate partner violence perpetration among men with HIV in northern Vietnam

BACKGROUND

Alcohol use is a known risk factor for male-perpetrated intimate partner violence (IPV), although few studies have been conducted globally and among men with HIV (MWH). We estimated the longitudinal effects of alcohol use on IPV perpetration among MWH.

METHODS

This study is a secondary analysis of randomized controlled trial data among male and female antiretroviral treatment patients with hazardous alcohol use in Thai Nguyen, Vietnam. Analyses were restricted to male participants who were married/cohabitating (N = 313). Alcohol use was assessed as proportion days alcohol abstinent, heavy drinking, and alcohol use disorder (AUD) using the Timeline Followback and Mini International Neuropsychiatric Interview questionnaire. Multilevel modeling was used to estimate the effects of higher versus lower average alcohol use on IPV perpetration (between-person effects) and the effects of time-specific deviations in alcohol use on IPV perpetration (within-person effects).

RESULTS

Participants with higher average proportion days alcohol abstinent had decreased odds of IPV perpetration (adjusted Odds Ratio [aOR] = 0.43, p = 0.03) and those with higher average heavy drinking and AUD had increased odds of IPV perpetration (Heavy drinking: aOR = 1.05, p = 0.002; AUD: aOR = 4.74, p < 0.0001). Time-specific increases in proportion days alcohol abstinent were associated with decreased odds of IPV perpetration (aOR = 0.39, p = 0.02) and time-specific increases in AUD were associated with increased odds of IPV perpetration (aOR = 2.95, p = 0.001). Within-person effects for heavy drinking were non-significant.

CONCLUSIONS

Alcohol use is associated with IPV perpetration among Vietnamese men with HIV. In this context, AUD and frequent drinking are stronger correlates of IPV perpetration as compared to heavy drinking.

Child Maltreatment Typologies and Intimate Partner Violence: Findings From a Danish National Study of Young Adults

The association between exposure to childhood maltreatment and subsequent intimate partner violence (IPV) has been well documented. Recently, there has been increased attention to IPV in adolescence and young adulthood, with studies demonstrating that IPV peaks in young adulthood. Data were collected from a Danish national study conducted by The Danish National Centre for Social Research in 2008 and 2009. A sample of 4,718 young adults (aged 24) was randomly selected using the total birth cohort of children born in 1984. Structured interviews were conducted with 2,980 participants equating to a response rate of 63%. Childhood maltreatment including emotional, sexual, and multiple abuse experiences and being female and a young parent were used to test the association with experiencing IPV victimization. Bivariate associations showed that all variables were significantly associated with experiencing IPV. When the variables were entered into a multivariate binary logistic regression analysis, being female indicated the strongest association (odds ratio [OR] = 13.96), followed by experiencing childhood sexual abuse (OR = 10.90) and experiencing multiple types of abuse (OR = 6.49). Results suggest that among the child maltreatment typologies, sexual abuse is the dominant factor associated with IPV. The current study extends the literature conducted on a young adult population by demonstrating that early adverse experiences and being female and a parent are associated with IPV in young adulthood. These findings suggest prevention programs should be targeted in early adolescence to support young people to establish and maintain positive and healthy relationships that promote safe conflict resolution strategies.

Poly-Strengths and Peer Violence Perpetration: What Strengths Can Add to Risk Factor Analyses

Adolescence is a high-risk time for perpetration of different forms of peer-based violence including harassment, bullying, and sexual assault. Research documents a number of important risk factors but less understood are protective factors like sense of mattering or how combinations of strengths may reduce perpetration risk. The current study examined how protective factors (i.e., positive social norms), including a diversity of strengths (termed poly-strengths), influenced the perpetration of harassment, bullying, and sexual assault for young people, while accounting for the use of alcohol both cross-sectionally and over time. Youth (N = 2232, 52.6% female) in grades 7-10 enrolled in a study using active parental consent (53% response rate) and completed online surveys in school that asked about bullying and harassment, alcohol use, positive social norms related to violence prevention, and a composite of intra-personal strengths. Follow-up surveys took place 6 months later (N = 2150). Logistic regression analyses examined how social norms and poly-strengths influenced odds of perpetration after accounting for demographic variables and the risk factor of alcohol use. Use of alcohol increased the odds of perpetrating all forms of violence. Strengths were significantly related to lower perpetration at Time 1 but not Time 2. Positive social norms reduced perpetration at both time points. The findings suggest adolescent perpetration of bullying, harassment, and sexual violence is lower in the presence of positive social norms over time and more proximally, in the presence of a diverse strengths portfolio. Prevention efforts that incorporate positive social norms and alcohol reduction strategies may reduce peer violence.

Trends in alcohol and marijuana detected in homicide victims in 9 US states: 2004-2016

Background

Use of alcohol and other drugs is a major risk factor for assaultive injuries and violent deaths. The purpose of this study was to examine the time trends in the prevalence of alcohol and marijuana detected in homicide victims.

Methods

We analyzed toxicological testing data for homicide victims (n = 12,638) from the 2004–2016 National Violent Death Reporting System in 9 US states (Colorado, Georgia, Massachusetts, New Jersey, Oregon, Rhode Island, South Carolina, Virginia, and Wisconsin). We used the Cochran-Armitage test for trend to assess the statistical significance of changes in the prevalence of alcohol and marijuana detected in these homicide victims during the study period.

Results

Overall, 37.5% of the homicide victims tested positive for alcohol, 31.0% positive for marijuana, and 11.4% positive for both substances. During the study period, the prevalence of marijuana increased from 22.3% (95% confidence interval [CI] = 19.6, 25.0) in 2004 to 42.1% (95% CI = 39.2, 44.9) in 2016 (Z = -15.7; P < .001) while the prevalence of alcohol declined slightly (Z = 1.5; P = 0.143). Marked increases in the prevalence of marijuana were observed in both sexes and across age and racial groups.

Conclusions

Marijuana is increasingly detected in homicide victims irrespective of demographic characteristics. Further research is needed to assess the causal role of marijuana use and concurrent use of marijuana and alcohol in homicide victimization.

Adolescent Bullying and Weapon Carrying: A Longitudinal Investigation

Using four data waves from an ongoing longitudinal study, we examined the longitudinal association between weapon carrying and bullying (i.e., bully, victim, bully-victim). Participants were 1,042 adolescents (55.9% female) recruited from Texas high schools, including Hispanic (31.7%), White (30.3%), African American (26.6%), and other (11.4%) with a mean age of 15.1 years at baseline. Multivariate logistic regression revealed that only baseline bully-victim was linked to weapon carrying and only 1 year later (Adjusted odds ratio = 1.76, 95% confidence interval: 1.08, 2.85), after controlling for baseline weapon carrying, age, gender, race, and parent education. No significant longitudinal association was found with bully or victim. Findings emphasize the importance of interventions targeting both bullying perpetrators and victims, while also highlighting the necessity of longitudinal research.

Neighborhood violent crime and adolescent relationship aggression

Research has shown that neighborhoods play a role in the etiology of violence. However, few adolescent relationship aggression (ARA) studies have objective measures of violent neighborhoods. Drawing on a nationally representative sample of youth, this study examines the association between ARA and local levels of violent crime (measured using geocoded Uniform Crime Report data from each of the youths' residential neighborhoods). Study analyses are based on survey data from 723 youth (ages 10-18) in current or recent dating relationships (351 males and 372 females) in the Survey on Teen Relationships and Intimate Violence (STRiV), a national representative household panel survey exploring interpersonal violence and related aggression among adolescents. About 19% of the sample reported ARA victimization in their most recent dating relationship (ARA perpetration was 17%). Neighborhood violent crime in the study (males living in 86.9 and females 99.8) was slightly lower than the national average of 100. With a broad national sample, 40% non-Whites, hypotheses guided by theories of neighborhood influence were tested. The study did not find an association between neighborhood violent crime and ARA victimization and perpetration, controlling for key demographic factors. The results, for a broad range of high- and low-crime neighborhoods, suggest that neighborhood violence does not seem to affect individual rates of ARA. The results suggest the ARA victimization and perpetration are perhaps ubiquitous and found both in low and high violent crime neighborhoods, suggesting that addressing local violent crime rates alone does not seem to be a path to also reducing ARA.

Adolescent Sexting Involvement Over 4 Years and Associations With Sexual Activity

PURPOSE

To investigate how demographic factors, dating, and sexual behaviors are related to both initial and changing rates of sexting over time, we examined sexting involvement among ethnically diverse adolescents over a 4-year period.

METHODS

A total of 1,042 participants from seven public high schools throughout southeast Texas (Dating it Safe study) were asked yearly about sexting involvement, as well as sexual and dating behaviors.

RESULTS

Using latent growth curve modeling, results revealed that males and white participants had greater initial involvement in sexting compared with females and Hispanic and other ethnicities, respectively. In addition, we found that sexting significantly increased over the 4-year period. Finally, participants who had sex and who had more dating partners at each wave were significantly more likely to be involved in sexting than their counterparts, even after controlling for their initial sexting involvement.

CONCLUSIONS

Involvement in sexting increases steadily from adolescence into emerging adulthood. The present study extends prior research by identifying a longitudinal association between sexting and sexual activity.

Trajectories of psychological dating violence perpetration in adolescence

BACKGROUND

More than one adolescent out of three will use psychological dating violence (DV) as a strategy to resolve conflict in romantic relationships, which will have major consequences on their partner's well-being. However, over time, most adolescents will learn skills to better interact and face conflicts, suggesting that psychological DV rates should decrease over time. Yet, because of individual characteristics and experiences, evolution over time may differ across adolescents. Risk factors for psychological DV have not been examined specifically, even though it is the most common form of dating violence.

OBJECTIVE

This study aimed to explore latent trajectories of psychological DV perpetration and examine risk factors predicting trajectory group membership.

PARTICIPANTS AND METHODS

A sub-sample of 449 adolescents who reported being in a dating relationship for the three waves of the [blind for review] completed printed and online self-report questionnaires.

RESULTS

Results from the group-based modeling identified 4 trajectories of psychological DV perpetration: absence of violence (30.7%), low violence (61.3%), high descending (4.2%), and moderate elevating (3.8%). Age, DV victimization, exposure to father toward mother violence, low self-esteem, marijuana use, DV victimization of peers, and antisocial behaviors of peers predicted trajectory membership. The model explained 36.7% of the variance.

CONCLUSIONS

These results support the need for a person-oriented approach to study psychological DV and for developing prevention programs adapted to the specific characteristics of vulnerable youth.

The Association Between Exposure to Violent Pornography and Teen Dating Violence in Grade 10 High School Students

Exposure to pornography in general has been linked with adolescent dating violence and sexual aggression, but less is known about exposure to violent pornography specifically. The current study examined the association of violent pornography exposure with different forms of teen dating violence (TDV) using baseline survey data from a sample of Grade 10 high school students who reported being in a dating relationship in the past year (n = 1694). Gender-stratified logistic regression models generated odds ratios adjusted for demographics, substance use, history of suspension/expulsion, gender equitable attitudes, and tolerance of rape myths to identify significant associations between violent pornography exposure and self-reported physical, sexual, and threatening TDV perpetration and victimization. Violent pornography exposure was associated with all types of TDV, though patterns differed by gender. Boys exposed to violent pornography were 2-3 times more likely to report sexual TDV perpetration and victimization and physical TDV victimization, while girls exposed to violent pornography were over 1.5 times more likely to be perpetrate threatening TDV compared to their non-exposed counterparts. Comprehensive prevention strategies for TDV may consider the potential risks associated with exposure to violent pornography, particularly for boys, and provide an alternative source of education about healthy sexual behavior and relationships.
