Brief report on a systematic review of youth violence prevention through media campaigns: Does the limited yield of strong evidence imply methodological challenges or absence of effect?

BackgroundWe present a brief report on a systematic review which identified, assessed and synthesized the existing evidence of the effectiveness of media campaigns in reducing youth violence.MethodsSearch strategies made use of terms for youth, violence and a range of terms relating to the intervention. An array of academic databases and websites were searched.ResultsAlthough media campaigns to reduce violence are widespread, only six studies met the inclusion criteria. There is little strong evidence to support a direct link between media campaigns and a reduction in youth violence. Several studies measure proxies for violence such as empathy or opinions related to violence, but the link between these measures and violence perpetration is unclear. Nonetheless, some evidence suggests that a targeted and context-specific campaign, especially when combined with other measures, can reduce violence. However, such campaigns are less cost-effective to replicate over large populations than generalised campaigns.ConclusionsIt is unclear whether the paucity of evidence represents a null effect or methodological challenges with evaluating media campaigns. Future studies need to be carefully planned to accommodate for methodological difficulties as well as to identify the specific elements of campaigns that work, especially in lower and middle income countries.     

Assessing the reliability,predictive and construct validity of historical,clinical and risk management-20 (HCR-20) in Mexican psychiatric inpatients

Introduction: Assessing dangerousness to gauge the likelihood of future violent behaviour has become an integral part of clinical mental health practice in forensic and non-forensic psychiatric settings, one of the most effective instruments for this being the Historical, Clinical and Risk Management-20 (HCR-20). Objective: To examine the HCR-20 factor structure in Mexican psychiatric inpatients and to obtain its predictive validity and reliability for use in this population. Method: In total, 225 patients diagnosed with psychotic, affective or personality disorders were included. The HCR-20 was applied at hospital admission and violent behaviours were assessed during psychiatric hospitalization using the Overt Aggression Scale (OAS). Construct validity, predictive validity and internal consistency were determined. Results: Violent behaviour remains more severe in patients classified in the high-risk group during hospitalization. Fifteen items displayed adequate communalities in the original designated domains of the HCR-20 and internal consistency of the instruments was high. Conclusion: The HCR-20 is a suitable instrument for predicting violence risk in Mexican psychiatric inpatients.     

El saber experiencial de las matronas de Atención Primaria en la detección de violencia de género durante el embarazo. Estudio cualitativo

AimTo use the reflections of primary care midwives to find out the barriers and facilitators for detecting IPV during pregnancy. The second aim is to determine proposals for measures to improve detection of IPV.MethodQualitative methodology with a interpretative phenomenological approach. In-depth interviews were conducted with 12 midwives, working in the sexual and reproductive health care centres of Hospitalet de Llobregat (Barcelona).ResultsThe difficulties in detection relate to the system of visits, the situation of women and barriers of practitioners themselves, such as fear. Follow-up of pregnancy and the relationship of trust with the midwife stand out as facilitators. The proposals for improvement were to increase training and use safe and reliable health care procedures.ConclusionsThe complexity of IPV makes it likely that IPV during pregnancy is undetected. It would be desirable to implement actions such as expanding training and agreeing on an internal work circuit that includes objective instruments to detect IPV, coordination with other services and ethical and legally appropriate way of recording in the clinical record.     

Are We Asking? Nurse Practitioners’ Interpersonal Violence Screening Practices

This cross-sectional study examined nurse practitioners’ (NPs’) intimate partner and sexual violence screening behaviors and identified associated factors. A survey invitation was mailed to 1000 primary care NPs, and the final sample included 170 NPs. The mean rate of violence screening was 18.9%. Of NPs who responded, 56% reported screening “almost none” of the female patients for violence during the past 3 months. Main concerns included time required to screen (32.3%) and disruption to clinic operations (18.3%). Nearly 80% of the NPs reported a need for additional training as a barrier to intimate partner and sexual violence screening.     

Conjugal violence: A comparison of violence against men by women and women by men

Because few studies demonstrated the types of violence performed by women, the aim of our study was to access violence men against women as well as women against men.A retrospective study was performed based on all the medical certificates for victims who consulted our centre specialized in assault victims.Eleven percent of the victims were men (81 men, 626 women). Episodes of violence were most often repeated against women than men (p < 0.05). Injuring, in most cases mild, were more frequently found in men than women (p < 0.01). They were primarily cutaneous in 66% of cases (85% men, 64% women) and severe in 5% of cases i.e. fractures, with no difference in gender. Three cases of sexual assault and one case of chemical submission was observed in women. Insults were made more often by men than by women (p < 0.002). A psychological impact was more frequently found in women than in men (p < 0.01). The duration of the total incapacity (incapacité totale de travail = ITT) was less than 0–3 days in most cases, and this occurred more often in 91% men than in 65% women (p < 0.01).Consultations for domestic violence occur less frequently in men than in women. Men present more often with injuries that are less severe compared to those observed in women. In contrast, the psychological impact is less frequent in men. Also episodes of violence were most often repeated when the aggressor was a man.     

Intimate partner violence against women in Spain: A medico-legal and criminological study

Intimate partner violence (IPV) is a significant worldwide problem whose magnitude and risk factors vary across different settings and cultures. Nowadays, it is a priority to improve the knowledge on this issue in order to formulate better evidence-based policy responses. This study aims to contribute to a better understanding of non-fatal IPV against women in Spain. A retrospective analysis of IPV cases with a final judicial decision was carried out. The period under study extended from January 2005 to December 2012, with a total of 582 files included in the investigation. Most IPV victims were young adult women of Spanish origin, either married or single, with children, unemployed and with a low family income level. The majority of alleged perpetrators were young adults, employed, with a middle-low income level, a history of alcohol consumption/abuse, but no criminal records. Most victims had previous history of IPV, were engaged in a long-term relationship with their abuser and lived with him at the time of assault. The combination of psychological and physical abuse was the most frequent form of violence. The most common mechanisms of assault consisted in minor acts of physical violence, which resulted in mild injuries, most of them in the upper limbs and face. Nearly half of women sought medical care, but physician's injury report was only made in about a quarter of these cases, even though it is mandatory for health professionals. The majority of criminal proceedings were initiated by the victim's report and ended in conviction, most of them being considered occasional mistreatment. This study confirms the heterogeneity of the phenomenon of intimate partner violence. The importance of adopting standard IPV concepts and promoting the recognition and assessment of this form of violence amongst health care professionals, criminal investigators and forensic personnel is emphasized.     

Feline mitochondrial DNA sampling for forensic analysis: When enough is enough!

Pet hair has a demonstrated value in resolving legal issues. Cat hair is chronically shed and it is difficult to leave a home with cats without some level of secondary transfer. The power of cat hair as an evidentiary resource may be underused because representative genetic databases are not available for exclusionary purposes. Mitochondrial control region databases are highly valuable for hair analyses and have been developed for the cat. In a representative worldwide data set, 83% of domestic cat mitotypes belong to one of twelve major types. Of the remaining 17%, 7.5% are unique within the published 1394 sample database. The current research evaluates the sample size necessary to establish a representative population for forensic comparison of the mitochondrial control region for the domestic cat. For most worldwide populations, randomly sampling 50 unrelated local individuals will achieve saturation at 95%. The 99% saturation is achieved by randomly sampling 60–170 cats, depending on the numbers of mitotypes available in the population at large. Likely due to the recent domestication of the cat and minimal localized population substructure, fewer cats are needed to meet mitochondria DNA control region database practical saturation than for humans or dogs. Coupled with the available worldwide feline control region database of nearly 1400 cats, minimal local sampling will be required to establish an appropriate comparative representative database and achieve significant exclusionary power.     

High prevalence of depression symptomology among adolescents in Soweto,South Africa associated with being female and cofactors relating to HIV transmission

Adolescents in HIV endemic settings are a priority demographic with respect to HIV prevention. Some studies have shown that behaviours associated with HIV transmission, may be mediated by mental health factors such as depression. We undertook this study to explore the prevalence and associations of depression symptomology among adolescents living in the HIV endemic community of Soweto, South Africa through the Botsha Bophelo Adolescent Health Study (BBAHS). We estimated the prevalence of depression using the Centre for Epidemiological Studies of Depression Scale, using a score of ≥24 to indicate ‘probable depression’. Among the 789 adolescents (14–19 years) with depression scores, 262 (33%) met the criteria for probable depression (99 [38%] men and 163 [62%] women; p = 0.061). In multivariable logistic regression, factors independently associated with depression included being female (AOR = 2.44, 95% CI: 1.45–4.00), marijuana use (AOR = 2.67, 95% CI: 1.21–5.93), physical violence (AOR = 1.63, 95% CI: 1.01–2.62), pregnancy (AOR = 2.00, 95% CI: 1.03–3.88) and incarceration (AOR = 2.09, 95% CI: 0.99–4.42). These data indicate that a concerning proportion of adolescents in Soweto may be suffering from depression and those screened as potentially depressed, were more likely to be female and have cofactors relating to increased risk for HIV. As part of a comprehensive HIV prevention strategy, we recommend that depression screening for adolescents be integrated into public and school health programs that triage those suffering into treatment programs.
