We present outcomes from a field test of a student-centered and technology-driven school safety framework. We describe the framework components rooted in school violence prevention. Results from our field test indicate moderate student and teacher use of the framework components, improvements in student perceptions of school safety, reductions in student reported peer victimization, and reductions in teacher and parent reported inappropriate student behavior. Consumer satisfaction rating were adequate. We present recommendations for implementing a school safety framework emphasizing student voice.

The current study tested differences in social network characteristics of high school students who report perpetrating sexual violence (SV) versus those who do not. N = 4554 students (49% male, 49% female, 2% another gender identity; 45% Hispanic, 43% white, 12% another racial identity) from 20 high schools reported how often they had perpetrated 13 sexually violent behaviors. Using their responses, students were classified as follows: non-perpetrators, sexual harassment perpetrators, low contact perpetrators, or high contact perpetrators. Students named up to 7 close friends and up to 7 trusted adults at their school and answered questions about other behaviors and attitudes. This information was used to assess (1) students’ connections with peers, (2) students’ connections with trusted adults, and (3) friends’ characteristics. Multilevel models indicated that compared to their peers, high contact perpetrators were less involved in the peer networks, less connected to trusted adults, and more likely to have friends who were involved in risky behaviors (e.g., sexual violence, homophobic name-calling, substance use). Low contact perpetrators were as connected to peers and trusted adults as non-perpetrators but were more likely to have friends engaged in sexual violence and homophobic naming-calling perpetration. By contrast, sexual harassment perpetrators were more involved and held higher status in the peer network (e.g., received more friendship nominations) but otherwise had similar friendship characteristics and similar connections to trusted adults as non-perpetrators. Building on these results, social network-informed SV prevention should use opinion leaders to change SV norms throughout the network and encourage new relationships between low- and high-risk students so as to disseminate norms that do not tolerate SV. Promoting connections to trusted adults also may be a useful avenue, especially for isolated adolescents. Trial Registration This study is registered at www.clinicaltrials.gov NCT01672541.

Homophobic name-calling and sexual violence are prevalent among US high school students and have been associated with a host of negative consequences including anxiety, depression, and substance use disorders, especially among sexual and gender minority youth. Although homophobic name-calling and sexual violence are linked to common risk and protective factors, most prior studies have failed to include gender and sexual minority groups. The present study used path analyses to explore the associations between eight protective factors and the outcomes of homophobic name-calling perpetration, homophobic name-calling victimization, sexual violence perpetration, and sexual violence victimization. The sample included LGB (n = 938), transgender (n = 140), and heterosexual (n = 3,744) high school students in Colorado, USA (N = 4,822). Protective factors included: (1) family support; (2) peer support; (3) friendships with trusted adults; (4) participating in healthy activities; (5) helping others; (6) spirituality; (7) access to counseling; and (8) access to medical services. For homophobic name-calling perpetration and victimization, significant negative associations emerged across different groups for the protective factors of family support, peer support, helping others, spirituality, counseling, and medical access. For sexual violence perpetration and victimization, significant negative associations emerged across different groups for the protective factors family support, peer support, and counseling access. Findings suggest that prevention and intervention efforts to address gender-based harassment should focus on building protective, supportive environments across the schools, families, and communities.

Bias-based aggression at school in the form of homophobic name-calling is quite prevalent among early adolescents. Homophobic name-calling is associated with low academic performance, higher risky sexual behaviors, and substance abuse, among other adverse outcomes. This longitudinal study examined risk and protective factors across multiple domains of the social ecology (individual, peer, family, school and community) and levels of analysis (within- and between-person) associated with homophobic name-calling perpetration and victimization. Students from four middle schools in the U.S. Midwest ( N = 1,655; [Formula: see text] age = 12.75; range = 10–16 years) were surveyed four times (Spring/Fall 2008, Spring/Fall 2009). For homophobic name-calling perpetration, significant risk factors included impulsivity, social dominance, traditional masculinity, family violence, and neighborhood violence; while empathy, peer support, school belonging, and adult support were significant protective factors. For homophobic name-calling victimization, significant risk factors included empathy (between-person), impulsivity, traditional masculinity, family violence, and neighborhood violence, while empathy (within-person), parental monitoring, peer support, school belonging, and adult support were significant protective factors.

African American heterosexual and sexual minority (SM) adolescents report widespread bullying victimization (BV), which is associated with poorer psychosocial functioning. However, studies examining potential protective factors that moderate this association are limited. Using data from a cross-sectional study conducted in Chicago, we examined the association between BV and psychosocial functioning among a sample of heterosexual (n = 475) and SM (n = 105) African American adolescents and examined whether four empirically-supported protective factors moderated these associations. Among SM adolescents, having close parents was protective against psychosomatic symptoms for those who reported high BV and having caring teachers was protective against substance use for those who reported both high and low BV. Among heterosexual adolescents, having close parents was protective against substance use for those who reported high BV but having high neighborhood support exacerbated the risk of developing psychosomatic symptoms for those who reported high BV. Implications for school and parental-based interventions are discussed.

Peer victimization, also referred to as bullying victimization, is associated with deleterious mental health outcomes including depression and suicidality. However, most of the bullying literature in the USA is centered around the experiences of non-Latinx White and African American adolescents. To center Latinx experiences, this cross-sectional study includes a sample of Latinx students from 19 Colorado high schools (n = 2554). School-level ethnic peer representation (proportion of Latinx peers) and individual student’s willingness to seek help were examined independently as moderators between bullying victimization and mental health outcomes (depression and suicidality) separately by gender. Results indicated that Latinx youth who experienced peer victimization also reported higher symptoms of depression and suicidality. A greater willingness to seek help was associated with less symptoms of depression and suicidality among young Latinx youth, while school-level ethnic peer representation was only associated with lower symptoms of depression for Latinx adolescent females. Among Latinx youth who were victimized, a greater willingness to seek help was protective for symptoms of depression and suicidality. Results suggest that school-based programs for bullying prevention and mental health promotion need to examine culturally specific protective factors to reduce victimization and promote help-seeking norms among Latinx youth.

The daily challenges resulting from all types of school violence-such as physical aggression, bullying, peer victimization, and general threats-have the potential to affect, longitudinally, students' mental health, school performance, and involvement in criminal or delinquent acts. Across primary and secondary studies, however, variation in how and how much school violence relates to these outcomes, has persisted. The purpose of this systematic review and meta-analysis, therefore, was to clarify this uncertainty by synthesizing the longitudinal relations. We conducted exhaustive searching procedures, implemented rigorous screening and coding processes, and estimated an underused effect size, the partial correlation from multiple regression models, before estimating a random-effects meta-analysis using robust variance estimation. We meta-analyzed 114 independent studies, totaling 765 effect sizes across 95,618 individual participants. The results of the overall analyses found a statistically significant longitudinal relation between school violence, in any role, and the aggregated outcome variables (rp = .06). Given that this effect size inherently controls for multiple potential confounding covariates, we consider the relation's magnitude clinically meaningful. We end by discussing ways practitioners and researchers may use these analyses when implementing prevention programming and how the field of meta-analysis should more frequently utilize the partial correlation.

This paper has two purposes: First, we describe the components of the Student Ownership, Accountability, and Responsibility for School Safety (SOARS) framework in the context of the literature on school safety. Second, we offer outcomes from a pilot study testing the framework's impact on student perceptions of: (a) school belonging, (b) sense of personal safety, (c) level of disruption, (d) level of delinquency, (e) responsibility for school safety, (f) engagement in victimizing behavior, and (g) sense of being victimized by peers. We conducted a study with two conditions, intervention and control. The study was conducted in Oregon and Illinois. Four high schools participated in the study. Two high schools received access to the SOARS framework and two high schools served as controls. We collected usage data of the Advocatr app, the central components of the SOARS framework, as well as survey data from students. We examined Advocatr use by overall frequency as well as across student race and gender. Survey data were analyzed using an ANCOVA analytic approach. Almost all outcomes were in the desired direction. Intervention effects on student-reported school belonging, sense of personal safety, and level of disruption reached statistical significance. Effect sizes ranged from small to medium, with the largest effect in students’ perceptions of personal safety. We contextualize our study in the literature on school safety and describe the alignment of the SOARS components with existing recommendations for increasing students’ safety at school.

Sexual violence (SV) among adolescents continues to be a major public health concern with numerous consequences. Research, predominantly with male collegiate samples, has suggested an association between sports participation and SV perpetration, and has included other important risk factors such as substance use and attitudes. However, more research is needed in this area among adolescents. The current study uses latent class analysis (LCA) to examine data- driven classes of high school student athletes (N = 665) engaged in three risk factor areas for SV: sport contact level, likelihood of substance use, and attitudes dismissive of SV. Once classes were enumerated and fit separately for male and female samples, pairwise comparisons were conducted on scores on two forms of SV (perpetration of sexual harassment and unwanted sexual contact) as a function of class membership. A 5-class solution was retained for both males and females. In the female sample, regarding SV—harassment, those most likely to perpetrate sexual harassment were those characterized by high likelihood of use of cigarettes, marijuana, alcohol, vape products, and those who played any type of sport. Too few females endorsed perpetration of unwanted sexual contact for pairwise comparisons to be conducted. For males, the classes most likely to perpetrate both forms of SV were those who were likely to endorse high likelihood to use of cigarettes, marijuana, alcohol, vape products, endorse attitudes dismissive of SV, and play any type of sport but especially high contact sports. These findings implicate high school athletic spaces as important venues for sexual violence prevention efforts.

School resource officers and other school security professionals (SSPs) (e.g., security specialists, guardians, campus monitors) have become increasingly common in schools; however, most states do not require that these professionals receive training related to understanding trauma and how it may affect students’ behavior and how to promote social–emotional learning competencies among students. The current project evaluated an online professional development program for SSPs that provides education on two topics related to best practices in working with youth in K-12 school settings: trauma-informed care (TIC) and social–emotional learning. This study used a posttest-only design of 96 SSPs from a county in the southeastern United States. Participants self-selected into two trainings: Cohort 1 (immediate intervention, May 2019) or Cohort 2 (delayed intervention–control group, August 2019). A linear regression model indicated that Cohort 1 (immediate intervention) scored significantly higher on TIC knowledge (b = .36, p

School resource officers (SROs) have become increasingly common in schools; however, most states do not require that they have youth- or school-related training (Morris et al. 2017). The intent of this project is to address potential gaps in training through the creation of four online professional development modules for SROs. Each module focused on one of the following: trauma-informed care; social-emotional learning (SEL); restorative problem-solving; and cultural competence. These modules were iteratively developed by applying established paradigms of curriculum development, that included systematic and communicative approaches, adult learning theory principles, and utilization of the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) Model of Systematic Instructional Design. SROs serve as law enforcers, informal counselors, and educators. It is imperative they are provided the opportunity to build their knowledge and develop applicable skills necessary for these roles and for working with students from all backgrounds.

Aggression among peers during adolescence is associated with deleterious developmental outcomes. Family violence has been strongly associated with many forms of aggression - such as verbal and physical aggression. Yet, associations between sibling and peer aggression at school and the protective role of school belonging remain understudied. Thus, the present study addresses this gap. Middle school students (N = 1611) completed self-report surveys four times across 2 years in a U.S. Midwest state. A multi-level within- and between-person longitudinal design was employed to examine associations among sibling aggression perpetration, witnessing intrafamilial violence, and verbal and physical peer aggression at school. Also, the moderating effect of school belonging between family violence and peer aggression was also investigated. Higher levels of sibling aggression were associated with higher verbal peer aggression at both within- and between-person levels. Family violence was associated with higher verbal and physical peer aggression, but only at the between-person level and not within-individuals. Higher school belonging was associated with less verbal and physical peer aggression overtime. School belonging moderated the relation between sibling aggression and verbal as well as physical aggression; higher within-person level sibling aggression was associated with lower verbal and physical aggression when students reported a strong sense of school belonging. Aggression prevention programs that focus on fostering school connectedness may mitigate the transmission of violence from home to school.

The current study, grounded in a social learning theoretical framework, examined attitudes and behaviors associated with verbal and physical teen dating violence (TDV) victimization. Because TDV varies by gender in both frequency and severity, these associations were examined first within the overall sample, and then by gender to further investigate these differences. A total of 1,884 adolescents (49.2% boys; 50.8% girls; average age 14.79 years; SD = .58) who reported ever dating someone were included in the analysis. Specifically, peers’ justification of TDV, attitudes supporting gender inequality, sexual activity, and peer victimization were included to determine their cross-sectional association with verbal and physical TDV victimization. Data were analyzed separately for boys and girls. Results indicated that peers’ justification of TDV, peer victimization, sexual activity, and attitudes supporting gender inequality were each associated with higher physical and verbal TDV victimization for girls and boys. Most of these factors remained significant when separated by gender, except for sexual activity and attitudes supporting gender inequality, which were not associated with physical TDV victimization for boys and girls, respectively. Implications for practice and research are discussed.

Adolescent violence, including sexual violence, homophobic name-calling, and teen dating violence, are public health problems that cause harm to many adolescents in the United States. Although research on the perpetration of these forms of adolescent violence has increased in recent years, little is known about perpetration rates across gender, race/ethnicity, and sexual orientation. To address this gap, the current study descriptively examined perpetration rates between and across different identities, including self-identified race/ethnicity, sexual identity, and gender identity. In Fall 2017, 9th - 11th grade students (N = 4782) at 20 high schools in Colorado (United States) completed a survey that assessed demographics (e.g., race/ethnicity, sexual identity, and gender identity) and various forms of violence perpetration. Compared to female adolescents, male adolescents reported significantly higher perpetration rates for: any sexual violence (27% vs. 17%); sexual harassment (26% vs. 15%); unwanted sexual contact (8% vs. 4%); and homophobic name-calling (61% vs. 38%). Differences in perpetration rates were also observed among various racial/ethnic, sexual, and gender minority students compared to non-minority students. This emphasizes a need for more research on how minority stress that results from the dynamics of intersecting identities and societal systems of power-including racism, sexism, homophobia, and transphobia-contributes to violence perpetration. Evidence-based violence prevention approaches, particularly strategies targeted at changing social norms about violence, gender, and sexuality, need to be tailored and evaluated for students with diverse cultural and social identities to ensure safe school climates for all students.

The current study tested differences in social network characteristics of high school students who report perpetrating sexual violence (SV) versus those who do not. N = 4554 students (49% male, 49% female, 2% another gender identity; 45% Hispanic, 43% white, 12% another racial identity) from 20 high schools reported how often they had perpetrated 13 sexually violent behaviors. Using their responses, students were classified as follows: non-perpetrators, sexual harassment perpetrators, low contact perpetrators, or high contact perpetrators. Students named up to 7 close friends and up to 7 trusted adults at their school and answered questions about other behaviors and attitudes. This information was used to assess (1) students' connections with peers, (2) students' connections with trusted adults, and (3) friends' characteristics. Multilevel models indicated that compared to their peers, high contact perpetrators were less involved in the peer networks, less connected to trusted adults, and more likely to have friends who were involved in risky behaviors (e.g., sexual violence, homophobic name-calling, substance use).

Evidence suggests that cyberbullying among school-age children is related to problem behaviors and other adverse school performance constructs. As a result, numerous school-based programs have been developed and implemented to decrease cyberbullying perpetration and victimization. Given the extensive literature and variation in program effectiveness, we conducted a comprehensive systematic review and meta-analysis of programs to decrease cyberbullying perpetration and victimization. Our review included published and unpublished literature, utilized modern, transparent, and reproducible methods, and examined confirmatory and exploratory moderating factors. A total of 50 studies and 320 effect sizes spanning 45,371 participants met the review protocol criteria. Results indicated that programs significantly reduced cyberbullying perpetration (g = −0.18, SE = 0.05, 95% CI [−0.28, −0.09]) and victimization (g = −0.13, SE = 0.04, 95% CI [−0.21, −0.05]). Moderator analyses, however, yielded only a few statistically significant findings. We interpret these findings and provide implications for future cyberbullying prevention policy and practice.

Latino(a) (also called “Latinx”) are the fastest growing ethnic population in the U.S.; however, there is a dearth of literature that examines intracultural bullying behaviors and their association with mental health and substance use for this population. The current study uses a person-centered approach to examine bully perpetration among Latinx high school students and association with substance use and mental health. Latent Class Analysis was used to identify classes of bullying perpetration among a sample of Latinx adolescents drawn from 9 Colorado high schools (n = 2929). Age and sex were used as predictors to examine differences between classes. Identified bullying classes were then related to mental health (i.e., depression and suicide ideation) and perceptions of future substance use. The latent class analysis identified five classes that included a high bully perpetration class (4.5%, n = 133), a moderate class (13.8%, n = 405), a class that reported high rates of teasing behaviors (13.5%, n = 396), a class that reported high rates of cyberbullying perpetration (7.3%, n = 215), and a low bully perpetration class (60.90%, n = 1780). Females reported lower odds of being in the High and Teasing classes compared to males. Further, the High and Cyberbullying perpetration classes reported the highest rates of depression, suicide ideation, and perception of future substance use compared to other classes. Understanding the risk profile of students who engage in bullying perpetration is essential in creating useful and appropriate resources and interventions. Inclusive efforts are needed to create more effective prevention programs that attend to the growing ethnic diversity among U.S. students.

Research has consistently linked homophobic bullying (e.g., teasing, name-calling, use of slurs) with an array of negative outcomes for children and adolescents. While most of the extant research covers risk factors related to homophobic bullying perpetration and victimization, there is a budding literature surrounding protective factors of these behaviors and their associated consequences. This article reviews 32 studies that focused on protective factors associated with homophobic bullying perpetration and victimization among children and adolescents. The review examines homophobic bullying as it applies to lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth and their heterosexual and cisgender peers. Using the social-ecological framework, this paper highlights protections at the individual level (e.g., sexual identity, self-esteem), the family level (e.g., social support at home), the peer level (e.g., positive friendships) and the school level (e.g., school policies against homophobic bullying, positive school climate). With the aim of contributing to the development of the field, directions for future research are also discussed.

The relationship between bully victimization and depression has been examined extensively with prior research showing long-term cascade of problems stemming from both exposure to victimization and depressive symptomology. However, prior research has failed to consider how protective factors may mitigate these long-term problems. Three theoretical models were tested: the interpersonal risk model, symptom driven model, and transactional model. The present study employs a novel statistical technique to explore longitudinal reciprocal associations among bullying, depression, and school belonging in a sample of 2177 middle school students (ages 11 to 15) in a Midwestern state. We used a model building process to explore the overall association between bully victimization, depression, and school belonging as well as a multi-group model in which models were estimated for boys and girls, separately. In our overall model, results indicated support for both symptom driven and interpersonal risk models. However, we did not find any significant buffering effect of school belonging. In our multi-group model, we found support for a buffering effect of school belonging for girls, but not boys. School belonging buffered long term problems associated with experiences of bully victimization via reductions in depression. Our findings point to the broader concept of school structure being differentially supportive and protective for various demographic groups and the need to consider the entire social ecology of a school when planning and implementing prevention interventions.

Suicide is a leading causes of death for adolescents, and is a developmental period with the highest rates of suicide attempts. Lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth are a high-risk population for suicidal ideations and behaviors when compared with their non-LGBTQ counterparts. However, a dearth of research exists on the protective factors for suicidal ideation and attempts specifically within the LGBTQ population. The current study proposes a model in which peer victimization, drug use, depressive symptoms, and help-seeking beliefs predict suicidal ideation and attempts among a statewide sample of LGBTQ adolescents. Among 4867 high school students in 20 schools, 713 self-identified as LGBTQ and had higher rates of attempts and ideation than their non-LBGTQ peers. Two logistic regression analyses were used to predict suicidal ideation and attempts among the 713 LGBTQ students (M = age 15 years). Results indicated that intentions to use drugs, peer victimization, and elevated depressive symptoms predicted both suicidal ideation and attempts. Additionally, help-seeking beliefs predicted suicidal attempts but not ideation, while the interaction of help-seeking beliefs and depressive symptoms significantly predicted suicidal ideation. These findings underscore the importance of increasing access to effective treatment services for depression and promoting safe and accepting school and community cultures for LGBTQ youth in particular.

Purpose Sexual and gender minority (SGM) youth (e.g., gay, lesbian, bisexual, questioning, transgender) are systemically impacted by victimization and poor mental health because of discrimination in society. To prevent adverse outcomes, we must understand factors that help communities support and protect SGM youth. This study examined to what extent protective factors longitudinally predict outcomes 2 years later in an effort to inform more sensitive prevention efforts. Methods Students from nine Colorado high schools (N = 2,744) completed surveys across four consecutive school semesters (T1 to T4). Structural equation modeling was conducted to determine the longitudinal associations between baseline protective factors (access to medical and counseling services, help-seeking beliefs, trusted adults, family support, peer support, spirituality) and distal adverse outcomes (substance use, depression, suicidal ideation, peer victimization, bullying perpetration, sexual violence victimization and perpetration, homophobic name-calling victimization, and perpetration), by sexual orientation. Results All protective factors examined, except for access to medical services, were associated with lower likelihood of adverse outcomes. Associations differed across sexual orientations. For students identified as questioning or something other than heterosexual, lesbian, gay, or bisexual, family support is a notable protective factor of depression, peer victimization, bullying perpetration, and sexual violence perpetration. Family support was not significantly protective for these outcomes among heterosexual, lesbian, gay, and bisexual students. Conclusions There is no singular protective factor or universally impactful intervention for public health. Public health initiatives should recognize intersectional identities of young people and build strategies that are relevant to specific identities to create more comprehensive and effective programing.

Lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth consume more digital media than their peers. This chapter offers an examination of the existing literature of pertinent theoretical frameworks, LGBTQ youth and their digital media use, as well as the potentially harmful impact these digital experiences may engender. The synthesis offers a broad illustration of the research in this area as well as identifies limitations in the field. Digital media offer useful tools for navigating some of unique developmental issues such as meeting partners, feeling supported, and getting sexual health information. However, these tools may be associated with risk and poor outcomes such as unsafe sexual behavior, sexual victimization, stigma within the LGBTQ community, body image issues, as well as potential criminal charges for producing and disseminating illegal sexual content. Challenges associated with this line of research are discussed and future directions are proposed.

Meta-analysts rely on the availability of data from previously conducted studies. That is, they rely on primary study authors to register their outcome data, either in a study’s text or on publicly available websites, and report the results of their work, either again in a study’s text or on publicly accessible data repositories. If a primary study author does not register data collection and similarly does not report the data collection results, the meta-analyst is at risk of failing to include the collected data. The purpose of this study is to attempt to locate one type of meta-analytic data: findings from studies that neither registered nor reported the collected outcome data. To do so, we conducted a large-scale search for potential studies and emailed an author query request to more than 600 primary study authors to ask if they had collected eligible outcome data. We received responses from 75 authors (12.3%), three of whom sent eligible findings. The results of our search confirmed our proof of concept (i.e., that authors collect data but fail to register or report it publicly), and the meta-analytic results indicated that excluding the identified studies would change some of our substantive conclusions. Cost analyses indicated, however, a high price to finding the missing studies. We end by reaffirming our calls for greater adoption of primary study pre-registration as well as data archiving in publicly available repositories.

Transgender youth peer relations is understudied when compared to lesbian, gay, and bisexual youth (LGB). Likewise, transgender youth of color (YOC) are also understudied given the difficulties associated with accessing the sample. This study examines the relations among peer victimization, school belonging, and mental health with an ethnically diverse sample of transgender adolescents (N = 4778). Invariance testing and structural equation modeling were employed to explore these relations as well as the potential moderating role of ethnic minority status. Findings demonstrate that an alarming number of transgender youth were exposed to victimization and that victimization predicted mental health issues like suicidal ideation. Furthermore, analyses showed that peer victimization was associated with diminished school belonging. School belonging was associated with better mental health and appeared to mediate the relation between victimization and mental health issues. Ethnic minority status did not moderate these associations. Implications for research are discussed.

This chapter reviews and discusses anti-bullying programmes in the United States. It begins with the definition and prevalence of bullying in the United States. It then evaluates several notable programmes that have been widely implemented in US school districts. The social-ecological framework has been applied to the conceptualization of bullying and peer victimization, which purports that bullying and peer victimization are influenced by individual, family, peer group, school, community, and societal contexts. Many of the intervention and prevention programmes, such as the Olweus Bullying Prevention Program and Social-Emotional Learning-based programmes such as Second Step Middle School Prevention Program, Steps to Respect, PATHS, Ruler, and Positive Action have been guided by the social-ecological framework. The chapter then includes the ‘five Ps of effective school-based research’.

Bystander intervention (i.e., a third party decides to defend a victim when witnessing a conflict) has been identified as an effective strategy to resolve bullying incidents (O’Connell, Pepler, & Craig, 1999). Researchers suggest that student willingness to intervene (WTI) is a robust predictor of bystander intervention (Nickerson, Aloe, Livingston, & Feeley, 2014). Toxic masculinity has been defined as “the constellation of socially regressive [masculine] traits that serve to foster domination, the devaluation of women, homophobia, and wanton violence” (Kupers, 2005, p. 71). Though some aspects of toxic masculinity (e.g., low empathy) have received some empirical attention regarding their role in determining prosocial behavior, many aspects of toxic masculinity have not. Little research has examined how constructs such as attitudes surrounding bullying and sexual harassment, social dominance orientation, and homophobic bullying are related to longitudinal changes in WTI across adolescence. The present study uses growth mixture modeling (GMM) to examine the heterogeneity of WTI among middle school boys in the Midwest (N = 805). Students were classified into three profiles of WTI over time: a “stable high” class (70.9%), a “decreasing” class (22%), and a “stable low” class (7.1%). When compared with the “stable high” class, students with higher levels of dominance and pro-bullying attitudes were associated with an 11% (AOR = 1.11, 95% CI [1.01–1.21] and a 55% (AOR = 1.55, 95% CI [1.05–2.31] increase in the odds of being in the “decreasing” class, respectively. Youth who reported higher rates of homophobic name calling perpetration had a 16% (AOR = 1.16, 95% CI [1.02–1.34] increase in the odds of being in the stable low class compared to the stable high class. Additionally, both homophobic name calling victimization and empathy were associated with a 17% (AOR = 0.83, 95% CI [0.70–0.98] and 18% (AOR = 0.82, 95% CI [0.69–0.98] lower odds of being in the stable low class. The findings support the theoretical framework which posits that features of toxic masculinity are associated with less WTI and thus carry implications for intervention design (Carlson, 2008; Leone et al., 2016).

Introduction Bullying is a widely prevalent public health and safety issue that can have serious long-term consequences for youth. Given the limited efficacy of traditional bullying prevention programs, a need exists for novel, theoretically informed, prevention programming. Construal Level Theory provides a useful framework. Methods This study evaluated a pseudo-randomized pilot trial of a virtual reality enhanced bullying prevention program among middle school students (N = 118) in the Midwest United States. Two models were proposed. The first predicts reductions in bullying behavior (traditional bullying, cyberbullying, relational aggression) at post-test, mediated by changes in empathy in the virtual reality condition compared to the control condition. The second predicts increases in school belonging and willingness to intervene as an active bystander at post-test, mediated by changes in empathy in the virtual reality condition compared to the control condition. Results The virtual reality condition yielded increased empathy from pre-to post-intervention compared to the control condition. Through the mediating role of empathy, changes in the desirable directions were also observed for traditional bullying, sense of school belonging, and willingness to intervene as an active bystander, but not for cyberbullying or relational aggression. Conclusions The scope and practical limitations of the virtual reality trial prevented a larger scale and more rigorous evaluation; however, results justify an expanded examination of virtual reality as a youth violence prevention tool.

Cyberbullying is recognized as a critical public health concern in the United States (Centers for Disease Control and Prevention 2009a, b; Srabstein et al. 2008; Ybarra and Mitchell 2004) and is broadly conceptualized as a digital version of peer-based aggression. Technological advances have significantly increased adolescents’ use of social media and online communication platforms, such as Facebook and Twitter. According to Hinduja and Patchin (2009), cyberbullying is defined as “willful and repeated harm inflicted through the use of computers, cell phone, or other electronic devices” (p. 5). Definitions and forms of cyberbullying vary, but some common examples include flaming, harassment, stalking, impersonation, outing, trickery/phishing, as well as exclusion. Utilizing technology, the perpetrator can send or post humiliating or threatening messages or photos of the victim to a third party or to a public forum visited by many online participants (Hinduja and Patchin 2009).

All too often, children and adolescents are exposed to violence and abuse in multiple settings (e.g., home, school, and communities), which may take the form of sexual abuse, physical assault, maltreatment, and bullying. Research over the years has made a significant contribution to enhancing our understanding of children’s lifetime exposure to emotional and physical violence. Indeed, the National Survey of Children’s Exposure to Violence found a large proportion of children reported experiencing more than one type of direct victimization (64.5%) and about 10.9% reported five or more exposures to different types of victimization. It also well known that children who were exposed to one type of violence are at a significant risk of experiencing other types of violence. Researchers have shown that similar risk and protective factors are associated with different forms of victimization and other type of problem behaviors that youth experience.

Introduction Bullying prevention remains a major focus for schools yet prevention programs have yielded limited efficacy. This suggests that efforts to make the programs more salient for youth may result in greater reductions in bullying behavior. Methods To inform the development of a text messaging-based bullying prevention program for middle school youth, we conducted two online, asynchronous focus groups with 37 youth in grades 6–8. Youth were recruited across the United States using an online panel. Topics and questions were posted twice-daily across three days; youth responded when convenient. Results Findings suggested: (a) When asked, many youth provided definitions of bullying that were simliar to the CDC's definition (e.g., differential power). At times, these did not align with their school's definition, however. (b) Youth said those who were ‘different’, quiet, or unpopular were more likely to be targeted by bullies; (c) Central tenants of bullying prevention programs (e.g., help-seeking, bystander interventions) did not always resonate with youth (e.g., becuase they could be hurt by the bully) although youth did share a range of strategies to manage anger; and (d) Many youth reported that bullying prevention efforts at their school were limited to posters and assemblies. Conclusions Asking students about their perspectives of the main tenants of bully prevention programs provides opportunities to craft prevention program content that better speaks to the experiences and concerns that youth have when trying to navigate these difficult situations. Focus groups are also useful in identifying the ways in which youth talk about bullying and other types of peer aggression to guide the ‘voice’ of the program.
