OBJECTIVE: Natural language processing and machine learning have the potential to lead to biased predictions. We designed a novel Automated RIsk Assessment (ARIA) machine learning algorithm that assesses risk of violence and aggression in adolescents using natural language processing of transcribed student interviews. This work evaluated the possible sources of bias in the study design and the algorithm, tested how much of a prediction was explained by demographic covariates, and investigated the misclassifications based on demographic variables.
METHODS: We recruited students 10-18 years of age and enrolled in middle or high schools in Ohio, Kentucky, Indiana, and Tennessee. The reference standard outcome was determined by a forensic psychiatrist as either a \"high\" or \"low\" risk level. ARIA used L2-regularized logistic regression to predict a risk level for each student using contextual and semantic features. We conducted three analyses: a PROBAST analysis of risk in study design; analysis of demographic variables as covariates; and a prediction analysis. Covariates were included in the linear regression analyses and comprised of race, sex, ethnicity, household education, annual household income, age at the time of visit, and utilization of public assistance.
RESULTS: We recruited 412 students from 204 schools. ARIA performed with an AUC of 0.92, sensitivity of 71%, NPV of 77%, and specificity of 95%. Of these, 387 students with complete demographic information were included in the analysis. Individual linear regressions resulted in a coefficient of determination less than 0.08 across all demographic variables. When using all demographic variables to predict ARIA\'s risk assessment score, the multiple linear regression model resulted in a coefficient of determination of 0.189. ARIA performed with a lower False Negative Rate (FNR) of 15.2% (CI [0 - 40]) for the Black subgroup and 12.7%, CI [0 - 41.4] for Other races, compared to an FNR of 26.1% (CI [14.1 - 41.8]) in the White subgroup.
CONCLUSIONS: Bias assessment is needed to address shortcomings within machine learning. In our work, student race, ethnicity, sex, use of public assistance, and annual household income did not explain ARIA\'s risk assessment score of students. ARIA will continue to be evaluated regularly with increased subject recruitment.

OBJECTIVE: Child maltreatment (CM) is a major risk factor across the lifespan. While research on CM and its consequences has risen strongly during the last decades, research is mainly focused on the prevalence of types of CM incidents. As valid prevalence rates on timing and chronicity of CM are lacking to date, we aimed to assess the timing of experienced CM by describing the age of onset, duration, and prevalence at each year of age for each CM subtype in a population-based sample.
METHODS: Cross-sectional, observational study in a representative sample.
METHODS: Using different sampling steps including a random route procedure, a probability sample of the German population above the age of 16, encompassing 2514 persons (50.6% female, mean age: 50.08 years) was generated. Participants were asked about sociodemographic information in a face-to-face interview, CM was assessed using the ICAST-R questionnaire.
RESULTS: The earliest mean age of onset was seen in neglect with 8.07 (±3.07) years for boys and 7.90 (±2.96) years for girls, while the mean age of onset for sexual abuse was in adolescence with 13.65 (±3.86) years for boys and 13.91(±3.17) years for girls. The overall duration of CM was lowest for sexual abuse with 2.12 (±2.01) years for boys and 2.35 (±1.73) years for girls, the highest duration was seen for emotional abuse with 4.00 (±3.54) years for boys and 4.21 (±3.77) years for girls.
CONCLUSIONS: Our novel results provide important epidemiological information for prevention efforts.

UNASSIGNED: Injuries, often preventable, prompted urgent action within the United Nations\' 2030 Agenda for Sustainable Development Goals (SDGs) to improve global health. South Africa (SA) has high rates of injury mortality, but accurate reporting of official national data is hindered by death misclassification.
UNASSIGNED: Two nationally representative surveys for 2009 and 2017 are utilised to assess SA\'s progress towards SDG targets for violence and road traffic injuries, alongside changes in suicide and under-5 mortality rates for childhood injuries, and compare these estimates with those of the Global Burden of Disease for SA.
UNASSIGNED: The surveys utilised multi-stage, stratified cluster sampling from eight provinces, with mortuaries as primary sampling units. Post-mortem files for non-natural deaths were reviewed, with additional data from the Western Cape. Age-standardised rates, 95% confidence intervals (CIs), and incidence rate ratios (IRRs) were calculated for manner of death rate comparisons and for age groups.
UNASSIGNED: The all-injury age-standardised mortality rate decreased significantly between 2009 and 2017. Homicide and transport remained the leading causes of injury deaths, with a significant 31% decrease in road traffic mortality (IRR = 0.69), from 36.1 to 25.0 per 100 000 population.
UNASSIGNED: Despite a reduction in SA\'s road traffic mortality rate, challenges to achieve targets related to young and novice drivers and male homicide persist. Achieving SA\'s injury mortality SDG targets requires comprehensive evaluations of programmes addressing road safety, violence reduction, and mental well-being. In the absence of reliable routine data, survey data allow to accurately assess the country\'s SDG progress through commitment to evidence-based policymaking.
Main findings The significant decrease in South Africa’s injury mortality rates between 2009 and 2017 appears to largely be driven by the significant 31% decrease in road traffic mortality rates.Added knowledge The 2009 and 2017 survey comparison provides an enhanced understanding of the profile for injury-related deaths, compared to misclassified vital statistics data, to track progress towards reaching Sustainable Development Goals.Global health impact for policy and action The significant reduction in road traffic mortality across all age groups suggests South Africa is making progress towards Sustainable Development Goal Target 3.6 for road safety. However, reducing violence, suicide, and newborn and under-5 injury mortality requires more targeted interventions.

UNASSIGNED: Escalating street violence and criminal homicides have an adverse impact on psychological well-being. However, these consequences have been difficult to evaluate. Using a recently validated scale, we aimed to assess the impact of fear of crime on the psychological status of middle-aged and older adults living in a rural setting afflicted by endemic violence.
UNASSIGNED: Participants were selected from Atahualpa residents included in previous studies targeting psychological distress in the population. A validated scale was used to objectively quantify fear of crime in participants. Differences in symptoms of depression and anxiety between baseline and follow-up were used as distinct dependent variables and the continuous score of the fear of crime scale was used as the independent variable. Linear regression models were fitted to assess the association between the exposure and the outcomes, after adjusting for relevant confounders.
UNASSIGNED: A total of 653 participants (mean age = 53.2 ± 11.5 years; 57% women) completed the requested tests. We found a 13% increase in symptoms of depression and anxiety during the peak of violence in the village compared with previous years. Linear regression models showed a significant association between the total score on the fear of crime questionnaire and worsening symptoms of depression (β = .24; 95% CI = 0.14-0.35) and anxiety (β = .31; 95% CI = 0.24-0.37), after adjustment for relevant confounders.
UNASSIGNED: This study shows a significant aggravating effect of fear of crime on pre-existing symptoms of depression and anxiety and a deleterious effect of these conditions on overall well-being.

This article aims to analyze the prevalence of reporting and notification of violence in children and adolescents in the work of clinical health professionals. The search was performed in six electronic databases and the gray literature for studies published until June 1, 2022. Estimates of interest were calculated using random effects meta-analyses. Two reviewers independently evaluated the potentially eligible studies according to the following criteria: cross-sectional studies carried out with health professionals who provided clinical care for children and adolescents and dealt with violence cases. Two reviewers extracted data on included trial characteristics, methods, and outcomes. Expectations of interest were transformed using random effects meta-analyses. The meta-analysis of the prevalence of reports of violence performed with 42 articles was 41%. The notification meta-analysis occurred with 39 articles and was 30%. About one in two health professionals face situations of violence against children and adolescents in their clinical practice (41%), and approximately one in three health professionals report the cases (30%).

OBJECTIVE: To identify the relationship between the violence-prevention climate and workplace happiness in hospitals. The secondary objective is to adapt a valid and reliable scale to a different culture in healthcare settings.
BACKGROUND: Healthcare settings are not immune to the harmful effects of violence, which can exacerbate existing challenges such as staff shortages. In the midst of these challenges, organizational efforts to ensure the safety of health workers are critical. These efforts can contribute positively to workers\' happiness or well-being.
METHODS: Using a cross-sectional design with 400 healthcare professionals from five hospitals in Trabzon, Turkey, data collection involved the Violence-Prevention Climate Scale and Workplace Happiness Scale. Confirmatory factor analysis was conducted to test the Turkish validity and reliability of the scale, and the consistency coefficient was calculated.
RESULTS: The findings revealed that, on average, employees exhibited high levels of violence-prevention climate ( x ¯ ${{\\bar{\\rm x}}}$  = 4.22) and moderate levels of workplace happiness ( x ¯ ${{\\bar{\\rm x}}}$  = 3.70). Subsequently, correlation analysis unveiled a statistically significant association between the dimensions of violence-prevention climate and workplace happiness (p < 0.05, r = 0.392). It was observed that those who experienced violence and did not feel safe in the workplace had lower levels of happiness.
CONCLUSIONS: The instances of healthcare workers being exposed to violence identified in the study largely align with previous theories related to both individual and organizational effects.
CONCLUSIONS: Violence-prevention climate affects the safety and workplace happiness of workers.
CONCLUSIONS: Employees expect their managers to seriously consider all reports of violence. In this context, creating a violence-prevention climate would be a good start. According to WHO 2030 targets, in an environment where there is a significant shortage of healthcare personnel, especially nurses, ensuring that existing employees work in a safer and happier environment will make a positive contribution to healthcare systems.

BACKGROUND: Colombia has high numbers of internally displaced people, forced to migrate due to the conflict. 1 in 3 displaced women undergo pregnancy during adolescence, compared to around 1 in 5 in the non-displaced population, alongside health and resource inequalities between these groups. There is limited qualitative information available from the perspectives of displaced women experiencing adolescent pregnancy. This research explores how structural violence may feature in their experiences.
METHODS: Qualitative methods were used. Participants were recruited with purposive sampling, using key informants and snowball sampling technique. 14 semi-structured interviews were conducted in Ciudad Bolívar, Bogotá, involving 11 displaced women who began childbearing age 15-19 in the past 10 years, and 4 participants\' mothers. Data was analysed using the theoretical framework of structural violence, and emergent themes categorised using thematic analysis.
RESULTS: Pregnancy was considered advantageous in many ways, but this was contradicted by resulting disadvantages that ensued. Structural violence was embedded in life stories, manifesting in poverty and difficulties accessing reliable income, poor access to healthcare and education following pregnancy. Institutional and interpersonal discrimination confounded these challenges.
CONCLUSIONS: Pregnancy during adolescence was a contradictory experience, representing both a safety net and a trap due to a complex interplay of structural and cultural violence in everyday survival. Policymakers must consider the importance of the context surrounding adolescent pregnancy and address systematic disadvantages affecting women in these positions.
The violent conflict in Colombia has left many people forced to leave their homes and become ‘internally displaced’. Internally displaced women are more likely to become pregnant during their adolescence than non-displaced women. This work tries to understand more about the everyday lives of displaced women who experience adolescent pregnancy, through interviews. The interviews were analysed and results interpreted using the theory of ‘structural violence’. Structural violence describes how social structures such as racism, sexism, war and poverty determine life choices, leading to suffering and inequality. The work found that pregnancy and motherhood in adolescence for displaced women was positive in many ways by bringing purpose, status and companionship. However, these women also experienced many challenges after pregnancy, such as exclusion from education and secure employment and difficulty accessing healthcare. This demonstrated that structural violence features in multiple interconnected forms in the daily lives of displaced adolescent mothers. The work urges policymakers to appreciate the complexity of context surrounding adolescent pregnancy and motherhood, and to address the structural disadvantages facing women in these situations.

BACKGROUND: The Safewards model aims to reduce conflict and use of containment on psychiatric wards. To evaluate the implementation of Safewards and understand why it is effective in some settings but not in others, it is important to assess the level of implementation fidelity. To do this, the Safewards Fidelity Checklist (SFC) is often used, which focuses on objective visual observations of interventions but does not include patient responsiveness. The latter is a key indicator of implementation fidelity and includes engagement, relevance, acceptability and usefulness. The aim of the present study was to investigate the fidelity of Safewards implementation on an acute psychiatric ward from the perspective of patient responsiveness.
METHODS: The study was conducted on a ward for patients with mainly affective disorders. To assess the general level of fidelity the SFC was used together with a detailed ward walkthrough. Ten patients were interviewed with a focus on patient responsiveness to each of the seven interventions implemented on the ward. Data were analysed using qualitative descriptive analysis.
RESULTS: The findings indicate high implementation fidelity, which was reflected in the SFC assessment, walkthrough and patient responsiveness. Patients gave examples of improvements that had happened over time or of the ward being better than other wards. They felt respected, less alone, hopeful and safe. They also described supporting fellow patients and taking responsibility for the ward climate. However, some patients were unfamiliar with a ward where so much communication was expected. Several suggestions were made about improving Safewards.
CONCLUSIONS: This study confirms previous research that patient responsiveness is an important factor for achieving fidelity in a prevention programme. The patients\' descriptions of the acceptability, relevance and usefulness of the specific interventions reflected to a high degree the objective visual observations made by means of the SFC and ward walkthrough. Patient engagement was demonstrated by several suggestions about how to adapt the interventions. There is potential to obtain valuable input from patients when adapting Safewards in practice. This study also presents many examples of practical work with these interventions and the effects it can have on patients\' experiences of care.
