School-based education programmes for the prevention of child sexual abuse

Web-Based Initiatives to Prevent Sexual Offense Perpetration: A Systematic Review

PURPOSE OF REVIEW

Web-based programs to prevent sexual offense perpetration could provide an opportunity that avoids many of the barriers associated with in-person treatment. The aim of this systematic review is to give an overview of the literature on web-based initiatives aimed at sexual offense perpetration prevention published during the last 10 years (2013-2023) and to report data on the efficacy as well as issues of the discussed initiatives.

RECENT FINDINGS

We included 18 empirical studies discussing web-based perpetration prevention initiatives, of which six are randomized controlled trials. Among the articles, four cover programs focusing on prevention of sexual reoffending and 14 discuss programs aimed at preventing initial sexual offenses. Evaluations and observations of web-based initiatives aimed at preventing sexual offense perpetration show overall promising results and are well-appreciated. However, evaluation studies are scarce and more randomized controlled trials replicating this effect are warranted.

Evaluation of the Child Safety Matters Curriculum for Improving Knowledge about Victimization among Elementary School Children: A Randomized Trial

This project employed a randomized-control design to evaluate the effectiveness of the MBF Child Safety Matters® (CSM) curriculum. Six Georgia schools across 3 counties agreed to participate, and 136 K - 5th grade classrooms were randomized to either receive the CSM curriculum or be a wait-list control and to receive the curriculum after the evaluation. In total, 2,414 students participated at pretest (1195 CSM and 1219 control) and 2,260 participated at posttest (1159 CSM and 1101 control). Pre/posttests were collected from all students prior to the delivery of the CSM curriculum and again approximately a month later to measure knowledge gains related to child safety. Intervention students displayed a greater increase in knowledge for the information taught in the CSM program as compared to students who did not receive the intervention (d = .29).

Student Knowledge Gain Following the Second Step Child Protection Unit: the Influence of Treatment Integrity

Treatment integrity is an important yet understudied component of school-based prevention programming, particularly for sensitive topics such as child sexual abuse prevention (CSA). This study examined student- and teacher-level characteristics, including components of treatment integrity, that contributed to greater knowledge gain among students participating in the Second Step Child Protection Unit (CPU). The study was conducted with 1132 students and 57 teachers from four elementary schools enrolled in a randomized controlled trial of the CPU. Students were administered assessments at pre-test, post-test, 6-month follow-up, and 12-month follow-up. Teachers were observed and rated on Content Integrity (CI; adherence to content), Process Integrity (PI; teacher enthusiasm, encouragement, behavior management), and Dose Received (DR; student behavior and interest) when delivering the lessons. Hierarchical linear growth modeling indicated that students who received the CPU made gains in the knowledge of CSA concepts and skills over a 12-month follow-up period. Girls had significantly greater CSA knowledge than boys immediately after the intervention, with gender remaining significant even when accounting for level-3 variables. Older children had better knowledge scores at post-test, but growth over time results revealed that younger students made greater gains. For students in 2nd through 4th grade, CI was more important for post-test outcomes, while for all students, CI and grade taught were important to post-test scores. Teachers of lower grades had students with a faster growth rate on correct responses to vignettes. Implications for CSA prevention programming and future research are discussed.

Fidelity in school-based child sexual abuse prevention programs: A systematic review

The aim of this study was to systematically review and evaluate the quality of the school-based child sexual abuse prevention education research in terms of implementation fidelity. A comprehensive literature search in PsycINFO, Medline, Education Resource Information Centre (ERIC) and the Cochrane Central Register of Controlled Trials was conducted. Articles included peer-reviewed, primary research studies related to the delivery of child sexual abuse prevention education programs within school settings published since 1996. In total, 3993 articles were identified and screened by two raters. Of those, 17 articles met the inclusion criteria. Implementation fidelity quality was assessed across the domains of: Intervention Design, Training Providers, Intervention Delivery, Intervention Receipt and Enactment of Skills, using the National Institute of Health Behavioral Change Consortium (NIHBCC) Fidelity Checklist. No study was identified as achieving high fidelity. Five studies (29%) reported including measures or processes to monitor implementation fidelity. There is an opportunity to improve the reporting of implementation fidelity related information within the school-based child sexual abuse prevention literature. This will allow more meaningful interpretations of treatment effects and increase confidence that changes attributed to the intervention are due to the intervention itself. Recommendations for such improvements are provided.

Victimisation, poly-victimisation and health-related quality of life among high school students in Vietnam: a cross-sectional survey

Background

In high and upper-middle income countries poly-victimisation (exposure to multiple forms of victimisation) is associated with worse health-related quality of life (HRQoL) among adolescents. There is a lack of empirical evidence about these associations from low- and lower-middle income countries. The aims of this study were to examine the associations between exposure to 1) individual forms of victimisation and 2) poly-victimisation and the HRQoL of adolescents in Vietnam.

Method

A cross-sectional, anonymously-completed survey of high school students in Hanoi, Vietnam. Lifetime exposure to eight individual forms of victimisation and poly-victimisation were assessed using the Juvenile Victimisation Questionnaire Revised-2 (JVQ R2). Health-related quality of life was assessed using the Duke Health Profile Adolescent Version (DHP-A). Bi-variate analyses and multiple linear regressions were conducted to assess the associations between individual forms of victimisation, poly-victimisation and HRQoL among girls and boys.

Results

In total 1616/1745 students (92.6 %) completed the questionnaire. Adolescent girls had significantly worse HRQoL than boys in all domains, except disability. Different forms of victimisation were associated with different HRQoL domains among girls and boys. Cyber victimisation was the most detrimental to girls’ HRQoL while for boys maltreatment was the most detrimental. Experiences of poly-victimisation were associated with worse HRQoL in physical, mental, social and general health, lower levels of self-esteem and increased levels of anxiety, depression and pain domains among both sexes.

Conclusions

Among Vietnamese adolescents, experiences of individual forms of victimisation were associated with poorer HRQoL in specific domains; the most detrimental forms of victimisation varied for girls and boys. However, it was experiences of poly-victimisation that had the most detrimental impacts on the HRQoL of both sexes. Recognition of violence, including poly-victimisation, is still low in Vietnam. These data indicate that community education, prevention and early intervention programs to reduce violent victimisation and assist adolescents who have experienced it, with attention to gender differences, are needed in Vietnam.

Adolescent Health Interventions: Conclusions, Evidence Gaps, and Research Priorities

Adolescent health care is challenging compared to that of children and adults, due to their rapidly evolving physical, intellectual, and emotional development. This paper is the concluding paper for a series of reviews to evaluate the effectiveness of interventions for improving adolescent health and well-being. In this paper, we summarize the evidence evaluated in the previous papers and suggest areas where there is enough existing evidence to recommend implementation and areas where further research is needed to reach consensus. Potentially effective interventions for adolescent health and well-being include interventions for adolescent sexual and reproductive health, micronutrient supplementation, nutrition interventions for pregnant adolescents, interventions to improve vaccine uptake among adolescents, and interventions for substance abuse. Majority of the evidence for improving immunization coverage, substance abuse, mental health, and accidents and injury prevention comes from high-income countries. Future studies should specifically be targeted toward the low- and middle-income countries with long term follow-up and standardized and validated measurement instruments to maximize comparability of results. Assessment of effects by gender and socioeconomic status is also important as there may be differences in the effectiveness of certain interventions. It is also important to recognize ideal delivery platforms that can augment the coverage of proven adolescent health-specific interventions and provide an opportunity to reach hard-to-reach and disadvantaged population groups.

An Evidence-Based Education Program for Adults about Child Sexual Abuse ("Prevent It!") That Significantly Improves Attitudes, Knowledge, and Behavior

Here we describe the development of an evidence-based education program for adults about childhood sexual abuse (CSA), called Prevent It! Uniquely, the primary goal of this program was to change the behavior of participants, as well as to increase knowledge about CSA and positive attitudes toward it. A comprehensive review shows no previous similar approach. The program includes a detailed manual to allow standardized administration by trained facilitators, as well as multiple video segments from CSA survivors and professionals. A total of 23 program workshops were run, with 366 adults participating. Of these, 312 (85%) agreed to take part in the study. All completed baseline ratings prior to the program and 195 (63% of study sample) completed follow-up assessments at 3-months. There were no significant differences between the demographic make-up of the baseline group and the follow-up group. Assessments included demographic data, knowledge, attitudes, and several measures of behavior (our primary outcome variable). Behavioral questions asked individuals to select behaviors used in the previous 3-months from a list of options. Questions also included asking "how many times in the previous 3-months" have you "talked about healthy sexual development or Child sexual abuse (CSA) with a child you know"; "suspected a child was sexually abused"; "taken steps to protect a child"; or "reported suspected sexual abuse to police or child welfare"? The majority of attendees were women, with the commonest age group being between 30 and 39 years old. Approximately 33% had experienced CSA themselves. At 3-month follow-up there were highly statistically significant improvements in several aspects of behavior and knowledge, and attitudes regarding CSA. For example, the number of subjects actively looking for evidence of CSA increased from 46% at baseline to 81% at follow-up, while the number of subjects who actively took steps to protect children increased from 25% at baseline to 48% at follow-up. For general public adults, this is the first program designed using the current evidence base for effective training in CSA examining longer-term outcomes and the first to focus on actual behavioral outcomes. The results suggest it is highly effective and support its widespread use.

Implications for public health research of models and theories of disability: a scoping study and evidence synthesis

Background

Public health interventions that are effective in the general population are often assumed to apply to people with impairments. However, the evidence to support this is limited and hence there is a need for public health research to take a more explicit account of disability and the perspectives of people with impairments.

Objectives

(1) To examine the literature on theories and models of disability; (2) to assess whether or not, and how, intervention studies of effectiveness could incorporate more inclusive approaches that are consistent with these theories and models; and (3) to use the findings to draw out implications for improving evaluative study designs and evidence-based practice.

Review methods

The project is a scoping review of the literature. The first stage examines theories and models of disability and reflects on possible connections between theories of disability and public health paradigms. This discussion is used to develop an ethical–empirical decision aid/checklist, informed by a human rights approach to disability and ecological approaches to public health. We apply this decision aid in the second stage of the review to evaluate the extent to which the 30 generic public health reviews of interventions and the 30 disability-specific public health interventions include the diverse experiences of disability. Five deliberation panels were also organised to further refine the decision aid: one with health-care professionals and four with politically and socially active disabled people.

Results

The evidence from the review indicated that there has been limited public health engagement with theories and models of disability. Outcome measures were often insensitive to the experiences of disability. Even when disabled people were included, studies rarely engaged with their experiences in any meaningful way. More inclusive research should reflect how people live and ‘flourish’ with disability.

Limitations

The scoping review provides a broad appraisal of a particular field. It generates ideas for future practice rather than a definite framework for action.

Conclusions

Our ethical–empirical decision aid offers a critical framework with which to evaluate current research practice. It also offers a resource for promoting more ethical and evidence-based public health research that is methodologically robust while being sensitive to the experiences of disability.

Future work

Developing more inclusive research and interventions that avoid conceptualising disability as either a ‘burden’ or ‘problem’ is an important starting point. This includes exploring ways of refining and validating current common outcome measures to ensure that they capture a diverse range of disabling experiences, as well as generating evidence on meaningful ways of engaging a broad range of disabled children and adults in the research process.

Knowledge Gains Following a Child Sexual Abuse Prevention Program Among Urban Students: A Cluster-Randomized Evaluation

OBJECTIVES

We evaluated a school-based child sexual abuse (CSA) prevention program, Safe Touches, in a low-socioeconomic status, racially diverse sample.

METHODS

Participants were 492 second- and third-grade students at 6 public elementary schools in New York City. The study period spanned fall 2012 through summer 2014. We cluster-randomized classrooms to the Safe Touches intervention or control groups and assessed outcomes with the Children's Knowledge of Abuse Questionnaire. Hierarchical models tested change in children's knowledge of inappropriate and appropriate touch.

RESULTS

The intervention group showed significantly greater improvement than the control group on knowledge of inappropriate touch. Children in second grade and children in schools with a greater proportion of students in general (vs special) education showed greater gains than other participants in knowledge of inappropriate touch. We observed no significant change in knowledge of appropriate touch among control or intervention groups.

CONCLUSIONS

Young children benefited from a school-based, 1-time CSA prevention program. Future research should explore the efficacy of CSA prevention programs with children before the second grade to determine optimal age for participation.

School-based education programmes for the prevention of child sexual abuse

BACKGROUND

Child sexual abuse is a significant global problem in both magnitude and sequelae. The most widely used primary prevention strategy has been the provision of school-based education programmes. Although programmes have been taught in schools since the 1980s, their effectiveness requires ongoing scrutiny.

OBJECTIVES

To systematically assess evidence of the effectiveness of school-based education programmes for the prevention of child sexual abuse. Specifically, to assess whether: programmes are effective in improving students' protective behaviours and knowledge about sexual abuse prevention; behaviours and skills are retained over time; and participation results in disclosures of sexual abuse, produces harms, or both.

SEARCH METHODS

In September 2014, we searched CENTRAL, Ovid MEDLINE, EMBASE and 11 other databases. We also searched two trials registers and screened the reference lists of previous reviews for additional trials.

SELECTION CRITERIA

We selected randomised controlled trials (RCTs), cluster-RCTs, and quasi-RCTs of school-based education interventions for the prevention of child sexual abuse compared with another intervention or no intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the eligibility of trials for inclusion, extracted data, and assessed risk of bias. We summarised data for six outcomes: protective behaviours; knowledge of sexual abuse or sexual abuse prevention concepts; retention of protective behaviours over time; retention of knowledge over time; harm; and disclosures of sexual abuse.

MAIN RESULTS

This is an update of a Cochrane Review that included 15 trials (up to August 2006). We identified 10 additional trials for the period to September 2014. We excluded one trial from the original review. Therefore, this update includes a total of 24 trials (5802 participants). We conducted several meta-analyses. More than half of the trials in each meta-analysis contained unit of analysis errors.1. Meta-analysis of two trials (n = 102) evaluating protective behaviours favoured intervention (odds ratio (OR) 5.71, 95% confidence interval (CI) 1.98 to 16.51), with borderline low to moderate heterogeneity (Chi² = 1.37, df = 1, P value = 0.24, I² = 27%, Tau² = 0.16). The results did not change when we made adjustments using intraclass correlation coefficients (ICCs) to correct errors made in studies where data were analysed without accounting for the clustering of students in classes or schools.2. Meta-analysis of 18 trials (n = 4657) evaluating questionnaire-based knowledge favoured intervention (standardised mean difference (SMD) 0.61, 95% CI 0.45 to 0.78), but there was substantial heterogeneity (Chi² = 104.76, df = 17, P value < 0.00001, I² = 84%, Tau² = 0.10). The results did not change when adjusted for clustering (ICC: 0.1 SMD 0.66, 95% CI 0.51 to 0.81; ICC: 0.2 SMD 0.63, 95% CI 0.50 to 0.77).3. Meta-analysis of 11 trials (n =1688) evaluating vignette-based knowledge favoured intervention (SMD 0.45, 95% CI 0.24 to 0.65), but there was substantial heterogeneity (Chi² = 34.25, df = 10, P value < 0.0002, I² = 71%, Tau² = 0.08). The results did not change when adjusted for clustering (ICC: 0.1 SMD 0.53, 95% CI 0.32 to 0.74; ICC: 0.2 SMD 0.60, 95% CI 0.31 to 0.89).4. We included four trials in the meta-analysis for retention of knowledge over time. The effect of intervention seemed to persist beyond the immediate assessment (SMD 0.78, 95% CI 0.38 to 1.17; I² = 84%, Tau² = 0.13, P value = 0.0003; n = 956) to six months (SMD 0.69, 95% CI 0.51 to 0.87; I² = 25%; Tau² = 0.01, P value = 0.26; n = 929). The results did not change when adjustments were made using ICCs.5. We included three studies in the meta-analysis for adverse effects (harm) manifesting as child anxiety or fear. The results showed no increase or decrease in anxiety or fear in intervention participants (SMD -0.08, 95% CI -0.22 to 0.07; n = 795) and there was no heterogeneity (I² = 0%, P value = 0.79; n=795). The results did not change when adjustments were made using ICCs.6. We included three studies (n = 1788) in the meta-analysis for disclosure of previous or current sexual abuse. The results favoured intervention (OR 3.56, 95% CI 1.13 to 11.24), with no heterogeneity (I² = 0%, P value = 0.84). However, adjusting for the effect of clustering had the effect of widening the confidence intervals around the OR (ICC: 0.1 OR 3.04, 95% CI 0.75 to 12.33; ICC: 0.2 OR 2.95, 95% CI 0.69 to 12.61).Insufficient information was provided in the included studies to conduct planned subgroup analyses and there were insufficient studies to conduct meaningful analyses.The quality of evidence for all outcomes included in the meta-analyses was moderate owing to unclear risk of selection bias across most studies, high or unclear risk of detection bias across over half of included studies, and high or unclear risk of attrition bias across most studies. The results should be interpreted cautiously.

AUTHORS' CONCLUSIONS

The studies included in this review show evidence of improvements in protective behaviours and knowledge among children exposed to school-based programmes, regardless of the type of programme. The results might have differed had the true ICCs or cluster-adjusted results been available. There is evidence that children's knowledge does not deteriorate over time, although this requires further research with longer-term follow-up. Programme participation does not generate increased or decreased child anxiety or fear, however there is a need for ongoing monitoring of both positive and negative short- and long-term effects. The results show that programme participation may increase the odds of disclosure, however there is a need for more programme evaluations to routinely collect such data. Further investigation of the moderators of programme effects is required along with longitudinal or data linkage studies that can assess actual prevention of child sexual abuse.

Strategies to promote uptake and use of intimate partner violence and child maltreatment knowledge: an integrative review

BACKGROUND

Intimate partner violence (IPV) and child maltreatment (CM) are major social and public health problems. Knowledge translation (KT) of best available research evidence has been suggested as a strategy to improve the care of those exposed to violence, however research on how best to promote the uptake and use of IPV and CM evidence for policy and practice is limited. Our research asked: 1) What is the extent of IPV/CM-specific KT research? 2) What KT strategies effectively translate IPV/CM knowledge? and 3) What are the barriers and facilitators relevant to translating IPV/CM-specific knowledge?

METHODS

We conducted an integrative review to summarize and synthesize the available evidence regarding IPV/CM-specific KT research. We employed multiple search methods, including database searches of Embase, CINAHL, ERIC, PsycInfo, Sociological Abstracts, and Medline (through April, 2013). Eligibility and quality assessments for each article were conducted by at least two team members. Included articles were analyzed quantitatively using descriptive statistics and qualitatively using descriptive content analysis.

RESULTS

Of 1230 identified articles, 62 were included in the review, including 5 review articles. KT strategies were generally successful at improving various knowledge/attitude and behavioural/behavioural intention outcomes, but the heterogeneity among KT strategies, recipients, study designs and measured outcomes made it difficult to draw specific conclusions. Four key themes were identified: existing measurement tools and promising/effective KT strategies are underused, KT efforts are rarely linked to health-related outcomes for those exposed to violence, there is a lack of evidence regarding the long-term effectiveness of KT interventions, and authors' inferences about barriers, facilitators, and effective/ineffective KT strategies are often not supported by data. The emotional and sometimes contested nature of the knowledge appears to be an important barrier unique to IPV/CM KT.

CONCLUSIONS

To direct future KT in this area, we present a guiding framework that highlights the need for implementers to use/adapt promising KT strategies that carefully consider contextual factors, including the fact that content in IPV/CM may be more difficult to engage with than other health topics. The framework also provides guidance regarding use of measurement tools and designs to more effectively evaluate and report on KT efforts.

The Good Schools Toolkit to prevent violence against children in Ugandan primary schools: study protocol for a cluster randomised controlled trial

BACKGROUND

We aim to evaluate the effectiveness of the Good School Toolkit, developed by Raising Voices, in preventing violence against children attending school and in improving child mental health and educational outcomes.

METHODS/DESIGN

We are conducting a two-arm cluster randomised controlled trial with parallel assignment in Luwero District, Uganda. We will also conduct a qualitative study, a process evaluation and an economic evaluation. A total of 42 schools, representative of Luwero District, Uganda, were allocated to receive the Toolkit plus implementation support, or were allocated to a wait-list control condition. Our main analysis will involve a cross-sectional comparison of the prevalence of past-week violence from school staff as reported by children in intervention and control primary schools at follow-up.At least 60 children per school and all school staff members will be interviewed at follow-up. Data collection involves a combination of mobile phone-based, interviewer-completed questionnaires and paper-and-pen educational tests. Survey instruments include the ISPCAN Child Abuse Screening Tools to assess experiences of violence; the Strengths and Difficulties Questionnaire to measure symptoms of common childhood mental disorders; and word recognition, reading comprehension, spelling, arithmetic and sustained attention tests adapted from an intervention trial in Kenya.

DISCUSSION

To our knowledge, this is the first study to rigorously investigate the effects of any intervention to prevent violence from school staff to children in primary school in a low-income setting. We hope the results will be informative across the African region and in other settings.

Lessons learned from child sexual abuse research: prevalence, outcomes, and preventive strategies

Although child sexual abuse (CSA) is recognized as a serious violation of human well-being and of the law, no community has yet developed mechanisms that ensure that none of their youth will be sexually abused. CSA is, sadly, an international problem of great magnitude that can affect children of all ages, sexes, races, ethnicities, and socioeconomic classes. Upon invitation, this current publication aims at providing a brief overview of a few lessons we have learned from CSA scholarly research as to heighten awareness of mental health professionals on this utmost important and widespread social problem. This overview will focus on the prevalence of CSA, the associated mental health outcomes, and the preventive strategies to prevent CSA from happening in the first place.

How Much Child Sexual Abuse is "Below the Surface," and Can We Help Adults Identify it Early?

Child sexual abuse (CSA) occurs frequently in society to children aged between 2 and 17. It is significantly more common in girls than boys, with the peak age for CSA occurring when girls are aged 13-17. Many children experience multiple episodes of CSA, as well as having high rates of other victimizations (such as physical assaults). One of the problems for current research in CSA is different definitions of what this means, and no recent review has clearly differentiated more severe forms of CSA, and how commonly this is disclosed. In general we suggest there are four types of behavior that should be included as CSA, namely (1) non-contact, (2) genital touching, (3) attempted vaginal and anal penetrative acts, and (4) vaginal and anal penetrative acts. Evidence suggests that CSA involving types (2), (3), and (4) is more likely to have significant long-term outcomes, and thus can be considered has having higher-impact. From the research to date approximately 15% of girls aged 2-17 experience higher-impact CSA (with most studies suggesting that between 12 and 18% of girls experience higher-impact CSA). Approximately 6% of boys experience higher-impact CSA (with most studies suggesting that between 5 and 8% experience higher-impact CSA). The data also suggests that in over 95% of cases the CSA is never disclosed to authorities. Thus, CSA is frequent but often not identified, and occurs "below the surface" in the vast majority of higher-impact cases. Helping adults to understand "below the surface" CSA might help them to recognize it early, but there are very few indicators specific to CSA, making this a challenging goal to achieve. Nonetheless, given that CSA frequently occurs with other types of abuse, a training program that focuses on both CSA and other abuse may offer a method to allow both early recognition and prevention by adults in the general population.

Educational and skills-based interventions for preventing relationship and dating violence in adolescents and young adults

BACKGROUND

Educational and skills-based interventions are often used to prevent relationship and dating violence among young people.

OBJECTIVES

To assess the efficacy of educational and skills-based interventions designed to prevent relationship and dating violence in adolescents and young adults.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, PsycINFO, six other databases and a trials register on 7 May 2012. We handsearched the references lists of key articles and two journals (Journal of Interpersonal Violence and Child Abuse and Neglect). We also contacted researchers in the field.

SELECTION CRITERIA

Randomised, cluster-randomised and quasi-randomised studies comparing an educational or skills-based intervention to prevent relationship or dating violence among adolescents and young adults with a control.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed study eligibility and risk of bias. For each study included in the meta-analysis, data were extracted independently by GF and one other review author (either CH, JN, SH or DS). We conducted meta-analyses for the following outcomes: episodes of relationship violence, behaviours, attitudes, knowledge and skills.

MAIN RESULTS

We included 38 studies (15,903 participants) in this review, 18 of which were cluster-randomised trials (11,995 participants) and two were quasi-randomised trials (399 participants). We included 33 studies in the meta-analyses. We included eight studies (3405 participants) in the meta-analysis assessing episodes of relationship violence. There was substantial heterogeneity (I(2) = 57%) for this outcome. The risk ratio was 0.77 (95% confidence interval (CI) 0.53 to 1.13). We included 22 studies (5256 participants) in the meta-analysis assessing attitudes towards relationship violence. The standardised mean difference (SMD) was 0.06 (95% CI -0.01 to 0.15). We included four studies (887 participants) in the meta-analysis assessing behaviour related to relationship violence; the SMD was -0.07 (95% CI -0.31 to 0.16). We included 10 studies (6206 participants) in the meta-analysis assessing knowledge related to relationship violence; the results showed an increase in knowledge in favour of the intervention (SMD 0.44, 95% CI 0.28 to 0.60) but there was substantial heterogeneity (I(2) = 52%). We included seven studies (1369 participants) in the meta-analysis assessing skills related to relationship violence. The SMD was 0.03 (95% CI -0.11 to 0.17). None of the included studies assessed physical health, psychosocial health or adverse outcomes. Subgroup analyses showed no statistically significant differences by intervention setting or type of participants. The quality of evidence for all outcomes included in our meta-analysis was moderate due to an unclear risk of selection and detection bias and a high risk of performance bias in most studies.

AUTHORS' CONCLUSIONS

Studies included in this review showed no evidence of effectiveness of interventions on episodes of relationship violence or on attitudes, behaviours and skills related to relationship violence. We found a small increase in knowledge but there was evidence of substantial heterogeneity among studies. Further studies with longer-term follow-up are required, and study authors should use standardised and validated measurement instruments to maximise comparability of results.

The Enough Abuse Campaign: building the movement to prevent child sexual abuse in Massachusetts

This case study describes the Enough Abuse Campaign, a multidisciplinary, statewide effort to prevent child sexual abuse in Massachusetts. The study uses the Institute of Medicine's Framework for Collaborative Community Action on Health to provide a systematic description of the campaign's process of implementation, which includes: (a) developing a state-level infrastructure for child sexual abuse prevention, (b) assessing child sexual abuse perceptions and public opinion, (c) developing local infrastructures in three communities and implementing training programs focused on preventing perpetration of child sexual abuse, (d) facilitating changes in local communities to child-sexual-abuse-related systems, and (e) inviting Massachusetts residents to join an advocacy-based movement to prevent child sexual abuse. This case study concludes with future directions for the campaign and topics for future research related to child sexual abuse.

[Guidelines and evidence. Recent developments in medical child protection]

Medical child protection comprises different types of involvement of physicians in order to protect children and adolescents from abuse and neglect. This review gives an overview of historical and recent developments in medical child protection. The professional foundation of medical involvement in this field requires a debate on the following questions: Is there evidence for the diagnostic criteria of child abuse and neglect? How far are the principles of evidence-based medicine applicable to the development of guidelines in child protection?

Child maltreatment prevention: a systematic review of reviews

OBJECTIVE

To synthesize recent evidence from systematic and comprehensive reviews on the effectiveness of universal and selective child maltreatment prevention interventions, evaluate the methodological quality of the reviews and outcome evaluation studies they are based on, and map the geographical distribution of the evidence.

METHODS

A systematic review of reviews was conducted. The quality of the systematic reviews was evaluated with a tool for the assessment of multiple systematic reviews (AMSTAR), and the quality of the outcome evaluations was assessed using indicators of internal validity and of the construct validity of outcome measures.

FINDINGS

The review focused on seven main types of interventions: home visiting, parent education, child sex abuse prevention, abusive head trauma prevention, multi-component interventions, media-based interventions, and support and mutual aid groups. Four of the seven - home-visiting, parent education, abusive head trauma prevention and multi-component interventions - show promise in preventing actual child maltreatment. Three of them - home visiting, parent education and child sexual abuse prevention - appear effective in reducing risk factors for child maltreatment, although these conclusions are tentative due to the methodological shortcomings of the reviews and outcome evaluation studies they draw on. An analysis of the geographical distribution of the evidence shows that outcome evaluations of child maltreatment prevention interventions are exceedingly rare in low- and middle-income countries and make up only 0.6% of the total evidence base.

CONCLUSION

Evidence for the effectiveness of four of the seven main types of interventions for preventing child maltreatment is promising, although it is weakened by methodological problems and paucity of outcome evaluations from low- and middle-income countries.

Interventions to prevent child maltreatment and associated impairment

Although a broad range of programmes for prevention of child maltreatment exist, the effectiveness of most of the programmes is unknown. Two specific home-visiting programmes-the Nurse-Family Partnership (best evidence) and Early Start-have been shown to prevent child maltreatment and associated outcomes such as injuries. One population-level parenting programme has shown benefits, but requires further assessment and replication. Additional in-hospital and clinic strategies show promise in preventing physical abuse and neglect. However, whether school-based educational programmes prevent child sexual abuse is unknown, and there are currently no known approaches to prevent emotional abuse or exposure to intimate-partner violence. A specific parent-training programme has shown benefits in preventing recurrence of physical abuse; no intervention has yet been shown to be effective in preventing recurrence of neglect. A few interventions for neglected children and mother-child therapy for families with intimate-partner violence show promise in improving behavioural outcomes. Cognitive-behavioural therapy for sexually abused children with symptoms of post-traumatic stress shows the best evidence for reduction in mental-health conditions. For maltreated children, foster care placement can lead to benefits compared with young people who remain at home or those who reunify from foster care; enhanced foster care shows benefits for children. Future research should ensure that interventions are assessed in controlled trials, using actual outcomes of maltreatment and associated health measures.
