Efficacy of Interventions to Prevent Physical and Sexual Dating Violence Among Adolescents: A Systematic Review and Meta-analysis

Online Human-Centered Design Methods are Acceptable, Appropriate, and Feasible for Generating Adolescent Relationship Abuse Intervention Ideas With Sexual and Gender Diverse Youth

PURPOSE

Sexual and gender diverse youth (SGDY) are at greater risk for adolescent relationship abuse (ARA) than cisgender heterosexual youth, but there are not enough evidence-based interventions for reducing ARA among SGDY. We piloted online human-centered design (HCD) methodology to engage SGDY in generating ARA intervention ideas. This study evaluated the acceptability, appropriateness, and feasibility of the online methods and identified SGDY-derived intervention ideas for reducing ARA.

METHODS

From August 2020 through March 2021, we conducted a longitudinal online HCD study with 46 SGDY (aged 14-18 years) recruited via social media from across the United States. SGDY completed HCD activities using MURAL (collaborative digital whiteboard) in four group-based sessions (1.5 hours each) and a follow-up survey with validated measures of acceptability, appropriateness, and feasibility (a priori success benchmarks: means > 3.75 on each five-point scale).

RESULTS

SGDY in the sample were 41% racial/ethnic minorities. SGDY rated the online HCD methods as highly acceptable, appropriate, and feasible (means ≥ 4.29). SGDY co-created a breadth of ARA intervention concepts across all social-ecological levels, including commonplace ideas (e.g., curriculum for schools) and novel ideas, such as social media-based interventions to foster healthy relationships, incentivization interventions for performing social justice work, and school plays with SGDY storylines.

DISCUSSION

Online HCD methods are acceptable, appropriate, and feasible for designing ARA intervention ideas. The intervention ideas generated in this study can help catalyze ARA intervention research for SGDY. Our method can be transported to other populations and health topics to help advance adolescent health and equity.

Interventions that address interpersonal violence experienced by adolescents globally: a systematic review of reviews

Globally, adolescents experience a significant burden of interpersonal violence, impacting their health, well-being and life trajectory. To address this, decision-makers need reliable evidence on effective interventions across various contexts.

OBJECTIVES

Synthesise the evidence for interventions addressing interpersonal violence experienced by adolescents aged 10-25 years.

METHODS

Six electronic databases were systematically searched. Systematic reviews and meta-analyses published globally between 2010 and 2022 were included if they reported interventions addressing interpersonal violence experienced by adolescents. Results were synthesised narratively.

RESULTS

35 systematic reviews were included, of which 16 were also meta-analyses. Majority of reviews included interventions set in high income countries (71%) and implemented in educational settings (91%). Effectiveness was reported in majority of interventions measuring victimisation and/or perpetration of intimate partner violence, sexual violence, bullying and/or cyberbullying (90%), majority of interventions measuring improvements in knowledge and attitudes towards violence (94%) and all interventions measuring bystander behaviour and improvements in well-being and quality of life. However, the quality of included reviews as per Assessment of Multiple Systematic Reviews 2 and National Health and Medical Research Council was low, and equity as per PROGRESS-PLUS was seldom considered. There was also a paucity of interventions addressing interpersonal violence in low-middle income countries (12%) and none of the included interventions specifically addressed interpersonal violence perpetrated in the home such as family violence.

CONCLUSION

There is some evidence of promising interventions to address interpersonal violence experienced by adolescents, however there are gaps in scope and implementation. There is a need for equity-oriented public health approaches to comprehensively address the disproportionate burden of interpersonal violence experienced by adolescents globally, including those at the highest risk of harm.

Boys perpetrating sexual harassment on peer girls in secondary school: A focus group study about pupils' experiences

AIMS

To explore experiences of sexual harassment of adolescent girls by peer boys during school hours.

METHODS

Focus group study with a convenience sample of six girls and 12 boys aged 13-15 years from two different lower secondary schools in Norway. Thematic analysis with Systematic Text Condensation was used with data from three focus group discussions, supported by theory about gender performativity.

RESULTS

Analysis demonstrated how girls experienced specific aspects of unwanted sexual attention perpetrated by male peers. When boys trivialized sexualized behaviour perceived as intimidating by girls, the behaviour was perceived as 'normal'. Among the boys, sexual name-calling was only meant as a joke to put the girls in their place, while girls were silenced. In this way, patterns of gendered interaction contribute to performing and maintaining sexual harassment. Responses from co-pupils and teachers had strong impact on further harassment, contributing to either escalation or resistance. Signalling disapproval when being harassed was difficult when bystander behaviour was lacking or degrading. The participants wanted teachers to intervene in response to sexual harassment, emphasizing that being present or showing concern is not enough to stop the harassment. The lack of proactive responses from bystanders may also represent gender performativity, where invisibility contributes to social conventions such as normalization.

CONCLUSIONS

Our analysis indicates a need for interventions targeting sexual harassment among pupils in Norwegian schools, with a special awareness of gendered performance. Both teachers and pupils would benefit from increased knowledge and skills in how to detect and stop unwanted sexual attention.

The Primary Prevention of Sexual Violence Against Adolescents in School and Community Settings: A Scoping Review

Sexual Violence (SV) is a public health problem with serious long-term consequences for victims. This scoping review aimed at summarizing the implementation, methodology, characteristics, and efficacy of SV prevention programs conducted in school and community settings with middle and high school students. This study also gathered recommendations for future research. Studies were searched in three databases: EBSCOHOST, SCOPUS and Web of Science. Eighty-six peer-reviewed empirical studies about SV prevention programs applied in school and community settings with samples of middle and high school students were analyzed. Most original studies (46.3%) used sexual violence outcomes, although many approached sexual violence in the context of dating violence (43.3%). Most SV prevention programs were applied in the U.S.A. although studies were identified across the globe. Prevention programs tend to reduce SV attitudes, perpetration, and victimization and to increase SV knowledge, as well as bystander attitudes and behaviors. The evidence reveals the efficacy of these programs, although future studies are needed to clarify the specificities of SV prevention. This article provides recommendations considering the measurement of SV outcomes, the role of technology, the involvement of adults and communities, the timing of interventions, sexual education, and reporting practices.

State laws addressing teen dating violence in US high schools: A difference-in-differences study

OBJECTIVE

Teen dating violence (TDV) is prevalent with lifelong adverse consequences, and strategies to reduce its burden are needed. Many U.S. states have enacted laws to address TDV in schools, but few studies have examined their effectiveness. This study aimed to assess whether state TDV laws were associated with changes in physical TDV victimization among high school students.

METHODS

We used repeated cross-sectional data of high school students from the Youth Risk Behavior Survey across 41 states from 1999 to 2019. Using a difference-in-differences approach with an event study design, we compared changes in past-year physical TDV in states that enacted TDV laws (n = 21) compared to states with no required laws (n = 20). Analyses accounted for clustering at the state-level and state and year-fixed effects. We conducted sensitivity analyses to assess the robustness of our findings.

RESULTS

In our sample of 1,240,211 students, the prevalence of past-year physical TDV was 9.2% across all state-years. In 1999, the prevalence of TDV at the state-level ranged from 7.5 to 13.0%; in 2019, the prevalence ranged from 3.7 to 10.5%. There was no significant association between TDV laws and past-year physical TDV. Six or more waves after enactment, we observed a non-significant 1.7% percentage point reduction in TDV in states with TDV laws (95% CI: -3.6 to 0.3 percentage points; p = 0.10).

CONCLUSIONS

We found no significant association between enactment of TDV laws and physical TDV among high school students. Further research is needed to understand how TDV laws are implemented and components of TDV laws that may influence effectiveness.

High School Follow-Up of the Dating Matters® RCT: Effects on Teen Dating Violence and Relationship Behaviors

Teen dating violence (TDV) is a significant public health problem that can have lifelong consequences. Using a longitudinal, cluster randomized controlled trial (RCT), this study examines whether the Dating Matters comprehensive prevention model, implemented in middle school, prevented TDV and negative relationship behaviors and promoted positive relationship behaviors in high school (9th-11th grades), when compared with a standard of care intervention. Dating Matters includes programs for sixth to eighth grade youth and their parents, training for school staff, a youth communications program, and policy and data activities implemented in the community. Self-report survey data were collected from students in 46 middle schools that were randomly assigned to condition within site. Students completed two surveys (fall and spring) in each middle school grade and a single survey in the spring of each high school grade. This study examined self-reported TDV perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills in the high school follow-up. While varying patterns emerged, latent panel models demonstrated significant program effects for all outcomes. Dating Matters students reported 19% reduced risk for TDV perpetration, 24% reduced risk for TDV victimization, 7% reduced risk for use of negative conflict strategies, and 3% more use of positive relationship skills, on average across time and cohort, than standard of care students. On average, Dating Matters, implemented in middle school, continued to be more effective at reducing TDV perpetration, TDV victimization, and use of negative conflict resolution strategies in high school than an evidence-based comparison program.Trial Registration: clinicaltrials.gov Identifier: NCT01672541.

What are practitioners' views of how digital health interventions may play a role in online child sexual abuse service delivery?

Introduction

Online child sexual abuse (OCSA) affects considerable numbers of children globally and is associated with a variety of mental health problems. Existing practitioner studies suggest that young people are infrequently asked about online abuse and practitioners have a fragmented understanding of the problems experienced or how they might approach them. There are very few evidence-based interventions that guide clinical assessment or practice. Digital Health Interventions (DHIs) have the potential to be an effective option where children and young people's services are challenged, including accessibility and anonymity. The aim of this study was to explore mental health practitioners' views of how DHIs may play a role in supporting young people who have experienced OCSA, and the role they can play in healthcare delivery.

Method

In-depth qualitative interviews and one focus group were conducted with 25 child mental health professionals across two sites (Manchester and Edinburgh). Data was analyzed using reflexive thematic analysis.

Results

Three overarching themes and 9 sub-themes were identified: (1) feeling a little bit lost; (2) seeing potential problems; and (3) knowing what works. Practitioners expressed interest in a DHI to support this client group and saw it as a way of managing waiting lists and complementing existing therapies. They felt that many young people would see this as a preferred medium to in-person therapy, would be empowering, and offers new ways of learning how to stay safe online. However, there were concerns about how much time would be needed by staff to deliver a DHI, anxieties about safety issues in relation to content and data protection, some of which may be unique to this population of young people, and concerns about the absence of a therapeutic relationship with vulnerable children.

Discussion

Our findings indicated that practitioners were uncertain about working with children subjected to OCSA but were receptive to the possibility of using a DHI to support their practice and to reduce waiting lists. Concerns were expressed about the time needed for staff training and support as well as concerns over patient safety and the lack of evidence about the effectiveness of an unsupported DHI.

Interventions to Prevent Intimate Partner Violence: A Systematic Review and Meta-Analysis

Intimate partner violence (IPV) remains a global health and human rights problem. This systematic review assesses the effects of preventive interventions on the occurrence of IPV experience or perpetration. Twenty-six studies published between January 1, 2008 and March 31, 2022 were included, contributing 91 effect sizes. Multilevel meta-analysis showed a protective pooled effect (risk ratio = 0.85, 95% CI [0.77, 0.99]). Interventions (also) including men were more effective than interventions for women only. No other moderators were found. Findings underscore that various IPV prevention interventions are now available that can improve the health and rights of women in diverse settings.

School-based interventions TO Prevent Dating and Relationship Violence and Gender-Based Violence: STOP-DRV-GBV systematic review

Background

Schools have a duty of care to prevent violence between students but a significant amount of dating and relationship violence and gender-based violence occurs in schools. These are important public health issues with important longitudinal consequences for young people.

Objectives

To understand functioning and effectiveness of school-based interventions for the prevention of dating and relationship violence and gender-based violence.

Review methods

We undertook a mixed-methods systematic review to synthesise different types of evidence relating to school-based interventions for the prevention of dating and relationship violence and gender-based violence to understand if, how and in what ways these interventions are effective. We searched 21 databases and 2 trial registers and undertook forwards and backwards citation chasing, author contact and other supplementary search methods. Searches identified all literature published to June 2021. All screening was undertaken in duplicate and independently, and we quality appraised all included studies.

Results

We included 247 reports (68 outcome evaluations, 137 process evaluations). Synthesis of intervention components produced an intervention typology: single-component, curricular, multicomponent, and multilevel programmes. Synthesis of intervention theories suggested that interventions aiming to increase students' sense of school belonging and sense of safety in the school building could encourage increased learning of prosocial skills and increased prosocial peer norms, and so potentially reducing dating and relationship violence and gender-based violence. Synthesis of factors affecting delivery highlighted school organisation and leaders who believed in the importance of addressing dating and relationship violence/gender-based violence, along with time and resources to deliver the interventions. The ease with which the intervention could be delivered and modified was also important. Meta-analysis found stronger evidence for intervention effectiveness in reducing dating and relationship violence than for gender-based violence, with significant long-term impacts on dating and relationship violence victimisation and perpetration, and some evidence that interventions in high-income countries could be effective for reducing victimisation and perpetration of gender-based violence in the long-term. Impacts on knowledge and attitudes were primarily short-term. Network meta-analysis did not suggest superiority of any intervention type. Moderation evidence suggested interventions reduced dating and relationship violence perpetration in boys more than girls, but reduced gender-based violence perpetration more in girls. Metaregression by intervention component did not explain heterogeneity in effectiveness, but qualitative comparative analysis suggested that reducing perpetration was important to reducing victimisation, and that perpetration could be reduced via focus on interpersonal skills, guided practice and (for gender-based violence) implementation of social structural components.

Limitations

Despite an exhaustive search, trials may have been missed and risk of publication bias was high for several analyses.

Conclusions

This is the most comprehensive systematic review of school-based interventions for dating and relationship violence and gender-based violence to date. It is clear that the prevention of dating and relationship violence and gender-based violence in schools will require longer-term investment to show benefit.

Future work

Future research is needed to understand why intervention effectiveness appears stronger for dating and relationship violence than gender-based violence.

Thoughts of self-harm in adolescents: Relationship with violence in the Dominican Republic

Violence against adolescents is a pressing health problem with long-term implications for future physical and mental well-being, such as thoughts of self-harm, which have been associated with suicidal ideation and completion. However, much of the research has been conducted only in high-income countries. This study aimed to examine the correlation between violence against adolescents and self-harm thoughts in La Romana, Dominican Republic (DR). Cross-sectional survey data was collected at a community-based clinic from participants aged 13-20. Participants were recruited through the clinic's adolescent program and peer referral, and verbal consent was obtained. A survey solicited information about each participant's demographics, experiences with violence, and thoughts of harm to self or others. The survey was completed by 49 adolescents. The mean age was 16.78 (SD 2.34); 65% were female. We performed t-tests and Fisher's exact to investigate the relationship between demographics, reported violence experiences and having self-harm thoughts. About half (45%) had experienced physical violence, 76% had experienced emotional violence, and 12% had experienced sexual violence. The most common perpetrators of physical and emotional violence were classmates (12% and 24%), and the most common perpetrator of sexual violence was an ex-partner (4.1%). Ten participants (20.4%) had thought about harming themselves. Self-harm thoughts were significantly associated with being female (p = 0.025), employed (p = 0.05), and to a higher number of experiences of physical (0.029) and sexual violence (p = 0.023). The results of this study suggest a high prevalence of both violence and self-harm thoughts in adolescents in the DR. Interventions that address physical and sexual violence against adolescents may be particularly important. Particular attention should also be paid to screening for self-harm thoughts in female-identifying adolescents. Further research is needed to better understand the relationship between violence and self-harm thoughts in adolescents in the DR.

Can Virtual Reality be Used for the Prevention of Peer Sexual Harassment in Adolescence? First Evaluation of the Virtual-PRO Program

Objective: The present study analyzed the Virtual-PRO program's efficacy in preventing peer sexual harassment by promoting the bystanders' active intervention and incorporating a virtual reality (VR) component. The impact of the program on sexist attitudes, moral disengagement, the intention to intervene as bystanders, and the involvement in sexual aggression and victimization was tested. Method: Virtual-PRO is a VR-enhanced sexual harassment curricular prevention program of six one-hour sessions. The evaluation comprised a pre-test, a post-test after the intervention, and a follow-up measure at three months. In the study, 579 Spanish adolescent students aged between 12 and 17 years (M = 14.76, SD = 0.88; 47.1% boys) were randomly grouped into experimental (n = 286) and control (n = 293) conditions. Results: The Virtual-PRO program effectively controlled participants' levels of sexism and reduced moral disengagement in the experimental group compared to the control group three months after the intervention. The program also showed positive results in changing bystander behavior, increasing the intention to intervene when the victim was not a friend. Finally, visual/verbal and online victimization decreased in the experimental group and increased in the control group. No differences were found for physical sexual victimization and sexual aggression. Conclusions: The first trial of the Virtual-PRO program is promising and highlights the use of VR as a sexual harassment prevention tool. Follow-up measures are essential to determine the impact of interventions accurately.

Exploring the Activities and Target Audiences of School-Based Violence Prevention Programs: Systematic Review and Intervention Component Analysis

Adolescents are at an increased risk for experiencing dating and relationship violence (DRV) and gender-based violence (GBV). School-based interventions remain an important and frequently used method for DRV/GBV prevention. A clear understanding and description of the different components of school-based interventions specific to DRV/GBV is needed to organize and advance the array of prevention efforts being utilized in school settings. We conducted an intervention component analysis to create a taxonomy for school-based interventions addressing DRV and GBV. We searched 21 databases in July 2020 and updated searches in June 2021, alongside extensive supplementary search methods. We included randomized controlled trials (RCTs) in adolescents of compulsory school-age that were implemented within the school setting which partially or wholly focused on DRV and GBV topics. Our analysis included 68 studies describing 76 different school-based interventions. Through an iterative coding process we identified 40 intervention components organized within 13 activity categories, including both student-directed components and non-student-directed components such as activities for school personnel and family members of students. We also identified components addressing higher levels of the social-ecological model including structural-social and structural-environmental aspects of DRV/GBV which prior reviews have not considered. This taxonomy of components and synthesis of intervention efficacy for DRV/GBV school-based interventions provides a framework for comparing past intervention evaluations and constructing new interventions to address these issues at multiple levels within a community.

Primary Versus Secondary Prevention Effects of a Gender-Transformative Sexual Violence Prevention Program Among Male Youth: A Planned Secondary Analysis of a Randomized Clinical Trial

Engaging adolescent males is a promising violence prevention strategy. This study explored primary versus secondary prevention effects of a gender-transformative program (i.e., Manhood 2.0) versus job-readiness training on multiple forms of violence perpetration. Adolescent males, ages 13 to 19 years, were recruited through youth-serving organizations in Pittsburgh, PA, between July 27, 2015, and June 5, 2017, to participate in an unblinded community-based cluster-randomized trial in 20 neighborhoods. The intervention curriculum, Manhood 2.0, focused on challenging norms that foster gender-based violence and building bystander skills. The control program was job-readiness training. We completed a planned secondary analysis of surveys from baseline and 9 months post intervention (follow-up), wherein we stratified participants based on any sexual violence/adolescent relationship abuse (SV/ARA) at baseline and examined risk of perpetration of SV/ARA, incapacitated sex, sexual harassment, cyber sexual abuse, peer violence, bullying, and homophobic teasing at follow-up. Among 866 participants, mean age was 15.6 years, 70% identified as Black, 6% as Hispanic, and 6% as multiracial. In both the Manhood 2.0 intervention group and job-readiness control groups, youth who reported SV/ARA at baseline were significantly more likely to report any form of SV/ARA, incapacitated sex, sexual harassment, cyber sexual abuse, bullying, and homophobic teasing at follow-up. Among participants who reported no SV/ARA perpetration at baseline, participating in the Manhood 2.0 intervention program was associated with increased risk of SV/ARA at follow-up compared to participating in the job-readiness control program. Among participants who reported SV/ARA perpetration at baseline, participating in the Manhood 2.0 intervention group was associated with lower risk of peer violence at follow-up. Synergizing gender-transformative approaches with job-readiness training may offer opportunities for crosscutting prevention programming to address multiple forms of violence.

Are school-based interventions to prevent dating and relationship violence and gender-based violence equally effective for all students? Systematic review and equity analysis of moderation analyses in randomised trials

School-based interventions for the prevention of dating and relationship violence (DRV) and gender-based violence (GBV) take advantage of universal opportunities for intervention. Information on differential effectiveness of interventions is important to assess if they ameliorate or worsen social gradients in specific outcomes. This is especially important in DRV and GBV prevention given the gendered context of these behaviours and their common aetiologies in patriarchal gender norms, and social acceptance in school contexts of sexual harassment, such as catcalling or unwanted groping. We undertook a systematic review of moderation analyses in randomised trials of school-based interventions for DRV and GBV prevention. We searched 21 databases and used supplementary search methods without regard to publication type, language or year of publication, and synthesised moderation tests relating to equity-relevant characteristics (principally sex and prior history of the outcome) for DRV and GBV perpetration and victimisation. Across 23 included outcome evaluations, programme effects on DRV victimisation were not moderated by gender or prior experience of DRV victimisation, but DRV perpetration outcomes were greater for boys, particularly for emotional and physical DRV perpetration. Findings for GBV outcomes were counterintuitive. Our findings suggest that practitioners should carefully monitor local intervention effectiveness and equity to ensure that interventions are working as intended. However, one of the most surprising findings from our analysis-with clear relevance for uncertainties in practice-was that differential impacts by sexuality or sexual minority status were not frequently evaluated.

Long-term Adverse Outcomes Associated With Teen Dating Violence: A Systematic Review

CONTEXT

Evidence suggests that teen dating violence (TDV) is associated with long-term adverse outcomes, but these associations have not been systematically assessed.

OBJECTIVES

To conduct a systematic review of the longitudinal associations between TDV and negative outcomes, including mental and physical health, reoccurrence of violence in intimate relationships, and high-risk behaviors (substance use and sexual behaviors).

DATA SOURCES

Peer-reviewed articles published in English were searched in PsycINFO/Eric/PsycArticles, PubMed, and Web of Science database from inception to November 2022.

STUDY SELECTION

Prospective studies that assessed TDV during adolescence, had a follow-up of at least ≥1 year, and evaluated the associations of TDV with health, violence in romantic intimate relationships, or risk behaviors were included.

DATA EXTRACTION

Study characteristics, baseline data, and follow-up outcomes were extracted from included studies.

RESULTS

Thirty-eight studies involving 23 unique samples were analyzed. Findings showed that TDV in adolescence was associated with future teen dating and intimate partner violence in adulthood. Studies also indicated that TDV was longitudinally associated with increasing high-risk behaviors (i.e., marijuana and alcohol use) and poor mental health outcomes (particularly for victimization). There was unclear evidence on the longitudinal link between TDV and suicidal attempts. Significant associations between TDV and negative outcomes were reported more frequently among females compared with males.

LIMITATIONS

Length of follow-up varied across studies.

CONCLUSIONS

Dating violence in adolescence may represent a risk factor for a wide range of long-term outcomes. Female adolescents reporting TDV may be at higher risk of adverse outcomes compared with males.

Exploring Social Norms and Control Coercive on Intimate Partner Violence in the Young. Implications for Prevention

This empirical work focuses on social norms as a way of transmitting psychological violence in young people, which could be affecting the effectiveness of preventive programs in dating violence. These programs are effective in changing beliefs, but new intervention approaches are in demand due to the former's limitations in achieving behavioral changes. The main objective of this study is to demonstrate that some dimensions of psychological violence are transmitted as a descriptive social norm, without any need of victimization. In a sample of 1,265 people (18-25 years old) and through two different studies, we explored the perception of prescriptive and descriptive social norms in situations of coercive control applied to three contexts (Study 1), isolation and domination (Study 2), under the hypothesis that coercive control is passed on as a descriptive social norm between peers. Characteristics describing diversity are taken into account. The results in frequency and Structural Equation Model analysis confirm the main hypothesis, because both perceptions are not correlated. Social norms no covariate with social characteristics. Same cannot be said of isolation and domination, leading to three conclusions for prevention. (1) Not all psychological violence works the same. Coercive control starts from a primary cognitive process that requires complementary actions, based for example on the cognitive hierarchy among social norms; (2) Preventive programs are often based on "prescribed" behaviors, related to the consequences they have on victims, whereas the descriptive social norm found in this study does not correlate with victimization, unless control is applied to specific contexts. Therefore, an additional effort in prevention could go deeper with more specific behaviors that show both the different types of psychological violence and the contexts of application; (3) Finally, at the policy level, results found call for the need for preventive efforts on psychological violence in the 18 to 25 age group and specific awareness campaigns.

School-Based Interventions to Prevent Dating and Relationship Violence and Gender-Based Violence: Systematic Review and Network Meta-Analysis

Background. Schools are sites of dating and relationship violence (DRV) and of gender-based violence (GBV) victimization and perpetration. School-based interventions can reach a broad range of students, targeting both individual and group processes that may underpin DRV and GBV. Considering DRV and GBV jointly is important because of their shared etiologies. Comparing the effectiveness of interventions using network meta-analysis (NMA) can support decision-making on optimal resource use. Objectives. To evaluate the comparative effectiveness of school-based interventions for children aged 5 to 18 years on DRV and GBV victimization, perpetration, and related mediators. Search Methods. We searched 21 databases in July 2020 and June 2021, alongside extensive supplementary search methods, including gray literature searches, forward and backward citation chasing, and searches on first and last author names. Selection Criteria. We included randomized-controlled trials of interventions for children of compulsory school age implemented within the school setting, and either partially or wholly aimed at changing DRV or GBV outcomes. Data Collection and Analysis. Pairwise meta-analyses using random-effects robust variance estimation considered intervention effectiveness on DRV and GBV victimization and perpetration using odds ratios, and on mediators (e.g., knowledge and attitudes) using standardized mean differences. Effects were divided into short-term (< 12 months postbaseline) and long-term (≥ 12 months postbaseline). NMAs on victimization and perpetration outcomes compared interventions categorized by breadth of mechanism and complexity of delivery and implementation. Meta-regression tested sensitivity to percentage of girls in the trial sample and country context. Main Results. Our analysis included 68 trials. Evidence was stronger overall for effects on DRV than for GBV, with significant long-term impacts on DRV victimization (odds ratio [OR] = 0.82; 95% confidence interval [CI] = 0.68, 0.99) and DRV perpetration (OR = 0.78; 95% CI = 0.64, 0.94). Knowledge and attitudinal effects were predominantly short-term (e.g., for DRV-related violence acceptance, d = 0.16; 95% CI = 0.08, 0.24). NMAs did not suggest the superiority of any intervention type; however, most analyses for GBV outcomes were inconsistent. A higher proportion of girls in the sample was associated with increased effectiveness on long-term victimization outcomes. Author's Conclusions. Evidence is stronger for DRV than for GBV, despite considerable heterogeneity. Certainty of findings was low or very low overall. Public Health Implications. Violence reductions may require more than 1 school year to become apparent. More extensive interventions may not be more effective. A possible reason for stronger effectiveness for DRV is that whereas GBV is ingrained in school cultures and practices, DRV is potentially more open to change via addressing individual knowledge and attitudes.

Relationship Between Dating Violence and Contraceptive Use Among Texas Adolescents

The recent overturning of Roe v. Wade has the potential to adversely impact reproductive health among adolescents experiencing unplanned pregnancies from dating violence. We examined the associations between contraceptive use and dating violence among Texas high schoolers in the years leading up to this new law. Youth Risk Behavior Surveillance System data from Texas 9th to 12th graders from 2011, 2013, 2017, and 2019 were analyzed. Multinomial logistic regression analyses examined the association between contraceptive use and key descriptive predictors (physical and/or sexual dating violence, survey year, age, sex, and race/ethnic group). Eleven percent of Texas adolescents surveyed reported experiencing either physical or sexual dating violence and 2% reported experiencing both types of violence. Those who experienced any dating violence were significantly more likely to report not using contraception versus those who did not experience violence (12.5% vs. 68.3%, p = 0.01). Adolescents who experienced any type of dating violence were more likely to report using hormonal contraception, condom use, or withdrawal versus those who did not experience dating violence. Hispanic adolescents were 63% more likely than their ethnic group counterparts to use no contraception (odds ratio [OR] 1.63; 95% confidence interval [CI] [1.11-2.40]). A significant proportion of Texas adolescents reported experiencing dating violence, and this group also reported higher noncontraception use versus those not experiencing dating violence. Given new strict Texas antiabortion laws, dating violence prevention and contraceptive use promotion to prevent unwanted reproductive outcomes such as sexually transmitted infections or unplanned pregnancies are imperative in this age group.

Dating Violence among Undergraduate Medical Students at a Public University in Mexico City: An Exploratory Study

Gender-based violence (GBV) and cyber-aggression are growing problems in Mexico, but there is a dearth of information on their associated risks. We aimed to determine the prevalence of dating violence (DV) and cyber-aggression in a public campus and compared students' acceptability of abusive DV based on their sex and sexual orientation. We employed a cross-sectional design to survey 964 first-year medical students attending a public university. We analyzed who found "acceptable" abusive behaviors from a dating partner and carried out descriptive analyses of sample characteristics by sex. We included 633 women and 331 men. Homosexual and bisexual orientation was lower among women (1.5%, 4.8%) vs. men (16.9%, 7.2%). Of women and men, respectively, 64.2% and 35.8% reported having been in a dating relationship. Experiencing abusive behaviors in the year prior to the study was associated with students' level of "acceptability". A total of 43.5% of the students who experienced cyber-aggression did not report any mental health consequences, 32.6% did not seek professional help, and 17.4% reported feeling depressed. Students that accepted emotionally abusive DV behaviors displayed a fourfold risk of experiencing physical abuse. Women and sexual minorities are more at risk of experiencing GBV and DV. More male students reported being victims of cyber-aggression.

Relationship Dynamics and Abusive Interactions in a National Sample of Youth and Young Adults

Stemming intimate partner violence among adults demands earlier education and skill-building supportive of healthy youth and young adult dating relationships. The current U.S.-based study examines a spectrum of youth and young adult relationship dynamics (RDs), inclusive of abusive interactions. In a nationally representative cohort of youth aged 10-18 at baseline and one parent or caregiver, survey responses regarding RDs from 618 participants ages 15-23 at wave 5 follow-up were analyzed. Latent class analysis of four positive dynamics, six problematic dynamics, and three scales of adolescent relationship abuse (ARA) were estimated, yielding four latent profiles of dating RDs. Relationships characterized by Unhealthy and Intense RDs both exhibited high probability of ARA but differed from each other in terms of other positive and problematic dynamics. Relationships characterized by Disengaged RDs had lower probability of ARA but elevated probability of awkward communications, negative feelings, social liability, and other challenging dynamics. Several baseline covariates were significantly associated with profiles of dating RDs approximately 5 years later. Younger participants were more likely to subsequently fall in an Intense or Disengaged RDs profile, as were participants with baseline emotional health problems. Further, classification in the Unhealthy RDs profile was less likely for participants reporting a better baseline relationship with their parents and more likely for those exposed to violence in childhood. These findings suggest that in addition to developmental maturity, youth and young adults would benefit from closer investigation and processing of past emotional and relational issues and traumas to foster healthier dating relationships.

Stop Sexual Harassment: A study protocol for a cluster randomised controlled trial in secondary schools in Norway

Background

Sexual- and gendered harassment are normalised in many peer groups, yet their associations with mental health concerns among adolescents are well-established. School based interventions that prevent and reduce sexual and gendered harassment among younger adolescents are scarce. For schools, protecting pupils from harassment may be challenging if the behaviour is trivialised among the pupils themselves. In the current study, the school intervention "Stop Sexual Harassment" was therefore developed to help teachers and pupils detect, address and stop sexual and gendered harassment among pupils ages 13-15 in Norwegian secondary schools.

Methods

In this study the effectiveness of "Stop Sexual Harassment" is evaluated via a cluster randomised controlled trial among pupils and teachers at 38 secondary schools. Schools were randomised into intervention and control groups. Primary outcomes are sexual and gendered harassment victimisation and perpetration, which will be assessed by the administration of questionnaires to pupils and teachers at baseline, and 2-, and 7-months follow-up. A process evaluation of the intervention implementation will be conducted through focus group interviews with pupils and teachers to gain insight about their experiences with the program components and implementation of the intervention.

Discussion

If the intervention yields positive effects, large-scale implementation of the program may be offered for secondary schools. The program may thus reduce sexual and gendered harassment among young adolescents.

Dropout Rate in Digital Health Interventions for the Prevention of Skin Cancer: Systematic Review, Meta-analysis, and Metaregression

BACKGROUND

Digital strategies are innovative approaches to the prevention of skin cancer, but the attrition following this kind of intervention needs to be analyzed.

OBJECTIVE

The aim of this paper is to assess the dropouts from studies focused on digital strategies for the prevention of skin cancer.

METHODS

We conducted this systematic review with meta-analyses and metaregression according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statements. Search terms for skin cancer, digital strategies, and prevention were combined to search PubMed, Scopus, Web of Science, CINAHL, and Cochrane Library from inception until July 2022. Randomized clinical trials that reported dropouts of participants and compared digital strategies with other interventions to prevent skin cancer in healthy or disease-free participants were included. Two independent reviewers extracted data for analysis. The Revised Cochrane Collaboration Bias tool was employed. We calculated the pooled dropout rate of participants through a meta-analysis of proportions and examined whether dropout was more or less frequent in digital interventions against comparators via an odds ratio (OR) meta-analysis. Data were pooled using a random-effects model. Subgroup meta-analyses were conducted in a meta-analysis of proportions and OR meta-analysis to assess the dropout events when data were sorted by digital interventions or control comparator. A univariate metaregression based on a random-effects model assessed possible moderators of dropout. Participants' dropout rates as pooled proportions were calculated for all groups combined, and the digital and comparator groups separately. OR>1 indicated higher dropouts for digital-based interventions. Metaregressions were performed for age, sex, length of intervention, and sample size.

RESULTS

A total of 17 studies were included. The overall pooled dropout rate was 9.5% (95% CI 5.0-17.5). The subgroup meta-analysis of proportions revealed a dropout rate of 11.6% for digital strategies (95% CI 6.8-19.0) and 10.0% for comparators (95% CI 5.5-17.7). A trend of higher dropout rates for digital strategies was observed in the overall (OR 1.16, 95% CI 0.98-1.36) and subgroup OR meta-analysis, but no significant differences were found between the groups. None of the covariates moderated the effect size in the univariate metaregression.

CONCLUSIONS

Digital strategies had a higher dropout rate compared to other prevention interventions, but the difference was not significant. Standardization is needed regarding reporting the number of and reasons for dropouts.

Assessment of Psychosocial Programs to Prevent Sexual Violence During Adolescence: A Systematic Review and Meta-analysis

IMPORTANCE

Sexual violence is a public health problem that affects adolescents globally. To our knowledge, no meta-analysis of prevention programs for adolescent sexual violence has been conducted.

OBJECTIVE

To perform a systematic review and meta-analysis of randomized clinical trials evaluating the efficacy of psychosocial programs for preventing sexual violence during adolescence.

DATA SOURCES

Peer-reviewed articles published in English were searched in PsycINFO, ERIC, PsycArticles, PubMed, and Web of Science databases through December 2021.

STUDY SELECTION

Studies were included if they were randomized clinical trials assessing the efficacy of a psychosocial prevention program targeting sexual violence and delivered to adolescents aged 10 to 19 years.

DATA EXTRACTION AND SYNTHESIS

Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify studies. The quality of individual studies was assessed with the Revised Cochrane Collaboration Risk of Bias tool. A random-effects model was used to pool odds ratios (ORs). Exploratory subgroup and metaregression analyses were performed to evaluate the associations between moderators and effect sizes.

MAIN OUTCOMES AND MEASURES

Primary outcomes were perpetration of sexual violence, experience of sexual violence, and a composite measure of any perpetration or experience of sexual violence.

RESULTS

Data were analyzed from 20 trials involving 37 294 adolescents. Compared with control conditions, prevention programs were associated with a significant reduction in the perpetration (OR, 0.83; 95% CI, 0.73-0.95; P = .005) and experience (OR, 0.87; 95% CI, 0.78-0.98; P = .02) of sexual violence, as well as a 13% significant reduction of any sexual violence (OR, 0.87; 95% CI, 0.78-0.97; P = .009). Exploratory analyses of the combination of program setting and participant age indicated that programs that were delivered in school settings and targeted at adolescents aged 15 to 19 years yielded significantly larger effect sizes (Cochran Q = 4.8; P = .03) compared with programs that were either delivered outside of a school setting or targeted younger adolescents. Quality assessment of trials revealed concerns of risk of bias across several included studies.

CONCLUSIONS AND RELEVANCE

In this meta-analysis, evidence suggested that prevention programs were associated with reducing adolescent sexual violence, especially when implemented at school with older adolescents. However, there is need for additional high-quality research. Prevention of adolescent sexual violence remains understudied compared with other similarly important public health prevention targets.

A Scoping Review of Digital Health Interventions to Promote Healthy Romantic Relationships in Adolescents

Despite a robust field of study in healthy romantic relationship education and risk prevention interventions that employ traditional forms of delivery, the field of digital health interventions (DHIs) in healthy relationship programming for adolescents remains undefined. The purpose of this scoping review was to summarize the scope of published research in DHIs that promote healthy romantic relationships in adolescents. We conducted database searches, 2000-2022; hand searches; reference list and literature review searches, and emailed study authors to identify articles. Included were experimental, development, and feasibility studies. We summarized features of selected studies and their healthy relationship aims/components and identified patterns of emphasis and areas of future need. Sixteen publications describing 15 unique DHIs were reviewed with interventions developed and or trialed in 11 countries. We identified 10 web-based or downloadable applications, four serious game applications, one video-voice program, and one social media-based program. DHIs focused on improving knowledge/attitudes/skills of healthy adolescent romantic relationships directly or through prevention-focused programs. Interventions that measured outcomes found small effects, primarily in healthy romantic relationship communication skills. DHIs offer unique opportunities to provide user-responsive and culturally specified programming for adolescents and to involve adolescents themselves in processes of program design, development, and evaluation. Further research is warranted to define relevant outcomes for adolescents and validated measures to evaluate them. Future research might seek to address the social ecology of adolescent romantic relationships beyond the individual and interpersonal and explore combinations of virtual and adult-moderated in-person delivery to ensure youth are adequately supported.

Sexual violence experiences among adolescent and young adult males: a review to empower healthcare providers

PURPOSE OF REVIEW

Despite 3-17% of adolescent and young adult males (AYAMs) experiencing sexual violence, there is a paucity of information regarding their sexual violence experiences leaving them vulnerable to dangerous and detrimental sequelae.

RECENT FINDINGS

There is underreporting and under-discussion of AYAMs' experiences of sexual violence, with disclosure influenced by societal perceptions of male sexuality, shame, and fear of discrimination. AYAMs experience sexual violence from individuals known to them, with many experiencing physical violence, threats, coercion, and electronic harassment. Intersectionality, previous traumas, inappropriate childhood exposures to sexually explicit situations, select online media consumption, and adverse childhood experiences (ACEs) increase the risk of sexual violence. AYAMs who experience sexual violence are at increased risk of re-victimization, perpetrating sexual violence, experiencing bodily harm, contracting sexually transmitted infections (STIs), and experiencing internalizing and externalizing symptoms, which can lead to significant morbidity and mortality. Research on male-specific protective and resilience factors is scarce and represents an ongoing need.

SUMMARY

After reviewing AYAMs' experiences of sexual violence, including risk and protective factors, media influences, detrimental sequelae, and resilience factors, we provide a screening framework to empower the healthcare provider (HCP) to champion tailored prevention, screening, intervention, and advocacy efforts to support AYAMs.

Psychological violence in dating relationships among adolescents: A systematic review and meta-analysis of prevention programs

Teen Psychological Dating Violence (TPDV) is a serious public health concern. However, there is limited evidence on the capacity of programs to prevent this form of violence. This study aimed to conduct a systematic review and meta-analysis of RCTs to evaluate the efficacy of prevention programs for TPDV. PsycINFO/Eric/PsycArticles, PubMed and Web of Science were searched from inception through January 2021 to identify RCTs of prevention programs for adolescents that reported a measure of TPDV. The effect sizes were computed as the difference between the prevention program and control group at post or follow-up assessment by calculating Hedges's g with a random-effect model. Thirteen trials met inclusion criteria and were included in the meta-analysis. There was a small but significant effect size in favor of the prevention group as compared to the control condition for victimization (g = 0.23; 95% CI, 0.10 to 0.37; p < 0.001) and perpetration (g = 0.24; 95% CI, 0.12 to 0.37; p < 0.001) of TPDV. Overall, the combined effect size for any TPDV perpetration/victimization was 0.22 (95% CI, 0.11 to 0.34; p < 0.001). Exploratory subgroup analysis showed that programs implemented at multiple levels (such as home, school, community) reported significantly larger effect sizes compared to single-level interventions. Significant differences in effect sizes were also associated with the type of scale used to assess TPDV. Current evidence suggests that intervention programs for TPDV may be effective, particularly when implemented at multiple levels. Further research focusing on refining tools to assess TPDV is needed.
