Efficacy of a randomized trial of a community and school-based anti-violence media intervention among small-town middle school youth

What Works in Violence Prevention Among Young People?: A Systematic Review of Reviews

Violence prevention programs aim to raise awareness, change attitudes, normative beliefs, motivation, and behavioral responses. Many programs have been developed and evaluated, and optimistic claims about effectiveness made. Yet comprehensive guidance on program design, implementation, and evaluation is limited. The aim of this study was to provide an up-to-date review of evidence on what works for whom. A systematic search of PsycINFO, MEDLINE, ERIC, and Sociology Collection ProQuest identified 40 reviews and meta-analyses reporting on the effectiveness of violence prevention programs among young people (age 15-30) in educational institutions, published before October 2018. These included reviews of programs designed to reduce (i) bullying, (ii) dating and relationship violence, (iii) sexual assault, and (iv) antisocial behavior. Only evaluations that reported on behavioral outcomes such as perpetration, victimization, and bystander behavior were included. The reviewed evaluations reported on programs that were mainly implemented in high-income countries in Europe and North America. The majority found small effects on violence reduction and victimization and increases in self-reported bystander behavior. Our findings expose critical gaps in evaluation research in this area and provide recommendations on how to optimize the effectiveness of future programs.

Interventions that address institutional child maltreatment: An evidence and gap map

Background

Child maltreatment has serious short and long-term negative impacts for those experiencing it. Child maltreatment occurring in institutional settings has recently received substantial attention. However, evidence about the effectiveness of interventions that prevent, disclose, respond to, or treat maltreatment that has occurred in these environments is fragmented and can be difficult to access. This evidence and gap map (EGM) collates this research evidence. It was developed as a resource for stakeholders operating in the child health, welfare and protection sectors, including practitioners, organisational leaders, policy developers and researchers, wanting to access high quality evidence on interventions addressing institutional child maltreatment.

Objectives

The objectives of this EGM were twofold: (a) To provide a structured and accessible collection of existing evidence from finalised and ongoing overviews of systematic reviews, systematic reviews and effectiveness studies of interventions addressing institutional child maltreatment-for those who work to fund, develop, implement and evaluate interventions aimed at ensuring children's safety in institutional settings; (b) to identify gaps in the available evidence on interventions addressing institutional child maltreatment-thereby helping to inform the research agendas of funders and other organisations.

Search Methods

A comprehensive search strategy identified relevant studies from published and grey literature, comprising: (1) 10 electronic academic databases; (2) five trial and systematic review registries; (3) nine organisational websites; (4) websites and reference lists of inquiry reports associated with seven international inquiries into child abuse and (4) the lists of included studies within systematic reviews identified by the search strategy. Members of this EGM's Subject Matter Experts group were also invited to forward relevant unpublished studies or grey literature.

Selection Criteria

The selection criteria were developed to identify finalised and ongoing overviews of reviews, systematic reviews and primary studies that reported on the effectiveness of interventions addressing child maltreatment (including sexual abuse, physical abuse, neglect and emotional abuse) within institutional settings. Eligible effectiveness study designs included: randomised controlled trials (RCTs), nonrandomised trials, controlled before-and-after studies and quasi-experimental studies. Reviews were eligible if they reported a systematic literature search strategy.

Data Collection and Analysis

All screening, data extraction, coding and critical appraisals were undertaken by two or more reviewers working independently, with discrepancies resolved via consensus or by a third reviewer. The titles and abstracts of studies identified by the search strategy were screened, and each full text of potentially relevant studies was further assessed for inclusion. Key data were extracted from all included studies and reviews. This included information about: publication details (e.g., year, author, country), inclusion/exclusion criteria (for reviews), study design, institutional setting, target population, type of maltreatment, intervention type and outcomes. Critical appraisal of included systematic reviews was achieved using the AMSTAR 2 tool, and completed RCTs were assessed using the updated Cochrane Risk of Bias 2.0 tool.

Main Results

Number of studies The electronic database search yielded 6318 citations, and a further 2375 records were identified from additional sources. Following deduplication and title/abstract screening, 256 studies remained for full text review. A total of 73 eligible studies (reported across 84 publications) met the inclusion criteria, including: 11 systematic reviews (plus, one update); 62 primary studies (including, three protocols for primary studies). Study characteristics The studies were conducted across 18 countries, however more than half (52%) were undertaken in the United States. Overall, most studies evaluated curriculum-based interventions delivered in educational settings, primarily aimed at the prevention of sexual abuse. Institutional setting: Most studies evaluated interventions in school or early learning environments (n = 8 systematic reviews; n = 58 primary studies). Far fewer studies examined other organisational settings. Out of home care (including foster care, residential care and orphanages), and social service organisations servicing children were minimally represented. No studies were identified where the primary setting was sports clubs, churches/religious organisations, summer/vacation camps, detention centres/juvenile justice settings, or primary/secondary health care facilities. Target population: Most interventions targeted children rather than adults (n = 7 systematic reviews; n = 47 primary studies) from the general population. Fewer studies included populations known to be at an increased risk, or those already exposed to maltreatment. Just over a third of the primary studies conducted an analysis to ascertain differences in the effect of an intervention between the genders. Intervention type: Prevention interventions were the most studied (n = 5 systematic reviews; n = 57 primary studies), with additional studies including prevention approaches alongside other intervention types. Fewer studies evaluated interventions targeting disclosure, institutional responses, or treatment interventions. Type of maltreatment: The vast majority of the studies assessed interventions solely addressing the sexual abuse of children (n = 8 systematic reviews; n = 45 primary studies). The remaining studies addressed other forms of maltreatment, including physical and emotional abuse, or neglect, either in combination or as a sole focus. Outcomes: Primary reported outcomes reflected the bias toward child targeted interventions. Outcome measures captured child wellbeing and knowledge outcomes, including measures of mental health, children's knowledge retention and/or self-protective skills. Measures of maltreatment disclosure or maltreatment occurrence/reoccurrence were less common, and all other outcome categories included in the EGM were minimally or not reported. A third of studies reported on some measure of implementation. Study quality The overall quality of the studies was low to moderate. Most systematic reviews were low-quality (n = 10), with only one high quality review (and update) identified. Most completed RCTs had some concerns relating to the risk of bias (n = 30), and the remainder were considered to be at a high risk of bias (n = 19).

Authors' Conclusions

This EGM has highlighted a substantial need for more high quality studies that evaluate interventions across a broader range of institutional contexts and maltreatment types. The current evidence base does not represent countries with large populations and the greatest incidence of child maltreatment. Few studies focussed on perpetrators or the organisational environment. Further evidence gaps were identified for interventions relating to disclosure, organisational responses and treatment, and few studies assessed interventions targeting perpetrators' maltreatment behaviours, recidivism or desistence. Future studies should also include measure of programme implementation.

Nonphysical Workplace Violence in a State-Based Cohort of Education Workers

BACKGROUND

The purpose of this study was to estimate the prevalence, identify risk factors, and assess the impact of nonphysical workplace violence (WPV) events among education workers (teachers, professionals, and support personnel).

METHODS

A cross-sectional survey was mailed to a random sample of 6450 education workers, stratified by sex, occupation, and school location in Pennsylvania. Multivariable logistic regression was performed to assess risk factors.

RESULTS

Of the 2514 participants, 859 (34%) reported experiencing at least one nonphysical WPV event during the 2009-2010 school year. Coworkers were the most common source of bullying. Most education workers responded that they did not receive an adequate response from their administration after reporting a nonphysical WPV event. Risks of nonphysical assaults increased for education workers who were female, those working in an urban school, and those in their first 3 years of working in their current school. Those assaulted were significantly likely to have low job satisfaction, find work more stressful, and have poor mental health compared to those were not assaulted.

CONCLUSIONS

Administration support for specific prevention efforts and post-event responses that address the risk factors for nonphysical WPV are essential for creating a positive, safe work environment in schools.

How can adolescent aggression be reduced? A multi-level meta-analysis

Aggressive behaviour among adolescents has significant social and economic costs. Numerous attempts have been made to intervene to reduce aggression in adolescents. However, little is known about what factors enhance or diminish intervention effectiveness. The present systematic review and meta-analysis, therefore, seeks to quantify the effectiveness of interventions to reduce aggressive behaviour in adolescents and to identify when and for whom such interventions work best. Sixteen databases were searched for randomised controlled trials that assessed interventions to reduce aggression among adolescents. After screening 9795 records, 95 studies were included. A multi-level meta-analysis found a significant overall small-to-medium effect size (d = 0.28; 95% CI [0.17, 0.39]). More effective interventions were of shorter duration, were conducted in the Middle East, were targeted at adolescents with higher levels of risk, and were facilitated by intervention professionals. Potentially active ingredients were classified using the Behaviour Change Technique Taxonomy. Behavioural practice and problem solving were components of more effective interventions targeted at the general population. Overall the findings indicate that psychosocial interventions are effective in reducing adolescent aggression. Future trials need to assess the effect of individual techniques and their combination to identify the key components that can reduce aggression in adolescents.

Características de las intervenciones realizadas con adolescentes en condición de sobrepeso y obesidad: una revisión integrativa

Introducción: Dado que el sobrepeso y la obesidad en la población adolescente van en aumento, es necesario identificar las intervenciones para la prevención y manejo de estas condiciones en el grupo de jóvenes. Objetivo: Presentar la evidencia encontrada, en relación con las características de las intervenciones publicadas en revistas científicas indexadas, sobre la prevención y manejo del sobrepeso y de la obesidad, respecto de la nutrición y la actividad física, para ser utilizada en la toma de decisiones, en cuanto a políticas y programas de promoción y prevención de esta condición de salud. Materiales y Métodos: Se realizó la revisión sistemática de estudios cualitativos y cuantitativos (desde descriptivos hasta experimentales, que incluyeran tanto revisiones sistemáticas como meta-análisis), publicados en el período comprendido entre 2005 y 2017, a través de las bases de datos PubMed y ScienceDirect, las bibliotecas virtuales Ovid y SciELO, y el compendio de revisiones Cochrane. Resultados: Existe gran variedad en diseño e implementación de las intervenciones, en cuanto a componentes, teorías, escenarios, evaluación de los efectos, dosis, tiempo y seguimiento, que tienen efecto en los hábitos nutricionales, en la actividad física, en la autoeficacia y en el índice de masa corporal (IMC) de la población estudiada. Discusión: La efectividad de las intervenciones varía, dependiendo de los componentes y de la fidelidad en la aplicación de la misma, lo cual debe revisarse a la luz de los mejores efectos encontrados. Conclusiones: 47 estudios cumplieron los requisitos de inclusión. Las intervenciones se robustecen con el uso de una teoría que direccione y fundamente los hallazgos que permitan dar mayores y mejores resultados. Los componentes de las intervenciones incluyen: duración, dosis, intensidad de la intervención, respuesta y seguimiento. Los adolescentes prefieren metodologías participativas e interactivas; sin embargo, aún no existe una intervención concreta y claramente definida que pueda ser estandarizada para enfrentar este problema de salud.

Trends and Correlates of Youth Violence-Prevention Program Participation, 2002-2016

INTRODUCTION

Adolescent participation in violence-prevention programming is critical in addressing the nation's elevated rates of youth fighting and violence. However, little is known about the secular trends and correlates of violence-prevention program participation in the U.S. Using national data, the authors examined the year-by-year trends and correlates of participation among American adolescents over a 15-year span.

METHODS

National trend data (2002-2016) were analyzed on non-Hispanic black/African American (n=35,216), Hispanic (n=45,780), and non-Hispanic white (n=153,087) youth aged 12-17years from the National Survey on Drug Use and Health in 2018. Consistent with the Centers for Disease Control and Prevention's trend analysis guidelines, the authors conducted logistic regression analyses with survey year specified as an independent variable and youth violence-prevention program participation specified as the dependent variable, while controlling for sociodemographic factors and other key correlates.

RESULTS

Youth participation in violence-prevention programs decreased significantly from 16.7% in 2002 to 11.7% in 2016, a 29% relative decrease in participation. A significant declining trend in participation over time was found across all sociodemographic subgroups examined and among youth reporting the use of violence and no use of violence in the past year. Participation among black/African American youth was significantly greater than Hispanic youth who, in turn, had significantlyhigher participation rates than white youth.

CONCLUSIONS

Youth participation in violence-prevention programming has decreased in recent years, with particularly large declines observed among younger adolescents (aged 12-14 years), youth in higher-income households, and youth reporting no past-year use of violence.

Promoção de saúde, participação em ações coletivas e situação de violência entre usuários da Atenção Primária à Saúde

RESUMO Este artigo visa a analisar a relação entre a promoção de saúde, mensurada por meio da participação em ações coletivas, e a violência entre usuários das unidades de saúde da atenção primária, no município de Ribeirão das Neves (MG). Trata-se de estudo de abordagem quantitativa, cuja metodologia consiste de entrevistas semiestruturadas com usuários da atenção primária do município de Ribeirão das Neves (MG). A análise estatística foi baseada em tabelas de frequências absolutas e percentuais para as distribuições uni e bivariada, destacando-se o perfil sociodemográfico. As associações e suas significâncias estatísticas foram avaliadas por meio do teste Qui-quadrado e da análise de correspondência. Foram entrevistados 628 usuários de 58 Unidades Básicas de Saúde; as violências mais frequentes foram: verbal, psicológica e tentativa de suicídio. A participação em ações coletivas está predominantemente ligada a cultos religiosos. O desenvolvimento de ações de prevenção à violência na atenção primaria é baixo. Na análise de correspondência, a baixa frequência de ações coletivas se associou fortemente à presença de violência e à tentativa de suicídio. A presença de ações ligadas a atividades esportivas/artísticas se associa à ausência de violência verbal e sexual; a participação em associações/sindicatos se associa à ausência de violência psicológica, física e tentativa de suicídio; por fim, ações de trabalho voluntário se associam à ausência de violência sexual, ter parente assassinado e conhecer alguém que foi assassinado. Concluiu-se que a participação e a não participação em ações coletivas se associam, respectivamente, com menor e maior prevalência de violência.

Effectively engaging stakeholders and the public in developing violence prevention messages

Background

Preventing family violence requires that stakeholders and the broader public be involved in developing evidence-based violence prevention strategies. However, gaps exist in between what we know (knowledge), what we do (action), and the structures supporting practice (policy).

Discussion

We discuss the broad challenge of mobilizing knowledge-for-action in family violence, with a primary focus on the issue of how stakeholders and the public can be effectively engaged when developing and communicating evidence-based violence prevention messages. We suggest that a comprehensive approach to stakeholder and public engagement in developing violence prevention messages includes: 1) clear and consistent messaging; 2) identifying and using, as appropriate, lessons from campaigns that show evidence of reducing specific types of violence; and 3) evidence-informed approaches for communicating to specific groups. Components of a comprehensive approach must take into account the available research evidence, implementation feasibility, and the context-specific nature of family violence.

Summary

While strategies exist for engaging stakeholders and the public in messaging about family violence prevention, knowledge mobilization must be informed by evidence, dialogue with stakeholders, and proactive media strategies. This paper will be of interest to public health practitioners or others involved in planning and implementing violence prevention programs because it highlights what is known about the issue, potential solutions, and implementation considerations.

Treatment integrity in school-wide programs: a review of the literature (1993-2012)

We assessed the reporting of treatment integrity in school-wide prevention programs in K-12 schools. This review was designed to determine (a) the extent to which treatment integrity was reported in school-wide prevention and intervention programs and how the reporting varied by research design, year, and journal; and (b) the procedures (e.g., method, frequency, informant) used to collect treatment integrity data. Results indicated that fewer than half of the studies in the review (n = 36, 45.6 %) measured and reported treatment integrity. Those studies reporting treatment integrity often used multiple methods and informants. Reporting treatment integrity in this body of literature has increased steadily over time.

Measuring the Effectiveness of Mass-Mediated Health Campaigns Through Meta-Analysis

A meta-analytic review was undertaken to examine the effects of mass communication campaigns on changes in behavior, knowledge, and self-efficacy in the general public. A review of the academic literature was undertaken and identified 1,638 articles from 1966 through 2012. Using strict inclusion criteria, we included 63 studies for coding and analyses. Results from these efforts indicated that campaigns produced positive effects in behavior change (r = .05, k = 61) and knowledge (r = .10, k = 26) but failed to produce significant increases in self-efficacy (r = .02, k = 14). Several moderators (e.g., health topic, the theory underlying the campaign) were examined in relation to campaign principles that are prescribed to increase campaign effects. The major findings are reviewed, and the implications for future campaign design are discussed.

The Effectiveness of an Intervention to Promote Awareness and Reduce Online Risk Behavior in Early Adolescence

The current study explored the effect of a school-based intervention on online risk awareness and behavior in order to shed light on a relatively unexplored field with high practical relevance. More than 800 Belgium primary school children (grade 4 and 6) were assessed at two measurements (n T1 = 812, 51.2 % female; n T2 = 819, 51.3 % female) before and after the intervention. Half of them received a 10 min classroom intervention indicating online risks. Children in the control group received a 10 min presentation concerning online applications without any emphasis on risks. Children in the intervention group were more likely to be aware of online risks directly after the intervention; this effect was still noticeable 4 months after. Reporting of online risk behavior in the intervention group was also higher compared to the control group who did not receive the intervention. Overall online risk awareness and online risk behavior were negatively associated and the awareness did not modulate the association between the intervention and online risk behavior. Furthermore, individual differences were assessed. Girls were more likely to be aware of online risks and asserted less online risk behavior than boys were. In line with the imperative in adolescence to become more risk taking, children in a higher grade were more likely to behave in a risky manner when online. The current study provides a valuable starting point for further research on how to decrease online risk behavior in early adolescence.

Impact of school-based health promotion interventions aimed at different behavioral domains: a systematic review

OBJECTIVE

Given that lifestyleshave similar determinants and that school-based interventions are usually targeted at all the risks that affect adolescents, the objective of this systematic review was to summarize the characteristics and effects of school-based interventions acting on different behavioral domains of adolescent health promotion.

METHODS

The review process was conducted by two independent reviewers who searched PubMed, Scopus, PsycINFO, and ERIC databases for experimental or observational studies with at least two measures of results published from 2007 to 2011, given that the research information available doubles every 5 years. Methodological quality was assessed with a standardized tool.

RESULTS

Information was extracted from 35 studies aiming to prevent risk behaviors and promote healthy nutrition, physical activity, and mental and holistic health. Activities were based on theoretical models and were classified into interactive lessons, peer mediation, environmental changes, parents' and community activities, and tailored messages by computer-assisted training or other resources, usually including multiple components. In some cases, we identified some moderate to large, short- and long-term effects on behavioral and intermediate variable.

CONCLUSIONS

This exhaustive review found that well-implemented interventions can promote adolescent health. These findings are consistent with recent reviews. Implications for practice, public health, and research are discussed.

What Your Data Didn’t Tell You the First Time Around: Advanced Analytic Approaches to Longitudinal Analyses

The present article describes the gap that exists between traditional data analysis techniques and more sophisticated methods that tend to be used more commonly among researchers outside of the study of v iolence against women. We briefly characterize growth models and person-centered analyses and describe the growing body of work in v iolence research that has applied these methods. Through an example from our own application of one of these techniques—latent class growth analysis—we highlight the ways that v iolence against women researchers may benefit from applying these more sophisticated methods to their own data, both past and present.

Use of mass media campaigns to change health behaviour

Mass media campaigns are widely used to expose high proportions of large populations to messages through routine uses of existing media, such as television, radio, and newspapers. Exposure to such messages is, therefore, generally passive. Such campaigns are frequently competing with factors, such as pervasive product marketing, powerful social norms, and behaviours driven by addiction or habit. In this Review we discuss the outcomes of mass media campaigns in the context of various health-risk behaviours (eg, use of tobacco, alcohol, and other drugs, heart disease risk factors, sex-related behaviours, road safety, cancer screening and prevention, child survival, and organ or blood donation). We conclude that mass media campaigns can produce positive changes or prevent negative changes in health-related behaviours across large populations. We assess what contributes to these outcomes, such as concurrent availability of required services and products, availability of community-based programmes, and policies that support behaviour change. Finally, we propose areas for improvement, such as investment in longer better-funded campaigns to achieve adequate population exposure to media messages.
