Violence typologies and sociodemographic correlates in South African adolescents: a three-wave cross-sectional study.

BACKGROUND: Violence victimisation and violence perpetration may co-occur in adolescents. Understanding the sociodemographic correlates of the independent and joint profiles of victimisation and perpetration may inform preventive interventions. This study examined the associations of sociodemographic factors with four violence typologies, namely, 1) non-involvement in both victimisation and perpetration, 2) victims only, 3) perpetrators only, and 4) victim-perpetrators. Trends in the prevalence of the four violence typologies over the three survey years were also examined. METHODS: We used data from the three nationally representative South African Youth Risk Behaviour Surveys conducted in 2002, 2008, and 2011 and included a multi-ethnic sample of adolescents (n = 30,007; boy: 46.9%, girls: 53.1%; M age = 16 years, SD = .06). RESULTS: The sample consisted of 8030 (30.8%) adolescents who had non-involvement in both victimisation and perpetration, 8217 were victims only (29.8%), 2504 were perpetrators only (9.0%), and 7776 were victim-perpetrators (24.6%). Logistic regression analyses showed that being a girl increased the odds of non-involvement (OR: 1.47, 99% CI: 1.36-1.58) and being victims only (OR: 1.90, 99% CI: 1.76-2.05). Being a boy increased the odds of being perpetrators only (OR: 0.42, 99% CI: 0.37-0.47) and victim-perpetrators (OR: 0.51, 99% CI: 0.47-0.55). Adolescents who did not have an absent mother had higher odds of non-involvement (OR: 0.78, 99% CI: 0.62-0.97). Lower monthly allowance increased the odds of victimisation only (OR: 0.99, 99% CI: 0.97-1.00), whereas higher monthly allowance increased the odds of perpetration only (OR: 1.05, 99% CI: 1.03-1.08). Trend analysis showed that between 2002 to 2011, there was an increase in the prevalence of non-involvement in adolescents (p < .001), a decrease in the prevalence of victims only (p < .05) and victim-perpetrators (p < .001), and no changes in the prevalence of perpetrators only (p > .05). CONCLUSIONS: Sociodemographic factors are uniquely associated with different violence typologies suggesting the need for tailored interventions to target adolescents with differed risks to violence victimisation and perpetration. Strengthening family relations, particularly between mother and child, may protect adolescents from the experiences of victimisation and perpetration.

Cuban medical training for South African students: a mixed methods study.

BACKGROUND: Achieving universal health care coverage will require greater investment in primary health care, particularly in rural and underserved populations in low and middle-income countries. South Africa has invested in training black students from disadvantaged backgrounds in Cuba and large numbers of these Cuban-trained students are now returning for final year and internship training in South Africa. There is controversy about the scheme, the quality and relevance of training received and the place of Cuban-trained doctors in the health care system. Exploring the experiences of Cuban- and South African-trained students, recent graduates and medical school faculty may help understand and resolve the current controversy. METHODS: Using a mixed methods approach, in-depth interviews and a focus group discussion were held with deans of medical schools, senior faculty, and Cuban-trained and South African-trained students and recent graduates. An online structured questionnaire, adapted from the USA medical student survey, was developed and administered to Cuban- and South African-trained students and recent graduates. RESULTS: South African students trained in Cuba have had beneficial experiences which orientate them towards primary health care and prevention. Their subsequent training in South Africa is intended to fill skill gaps related to TB, HIV and major trauma. However this training is ad hoc and variable in duration and demoralizing for some students. Cuban-trained students have stronger aspirations than those trained in South Africa to work in rural and underserved communities from which many of them are drawn. CONCLUSION: Attempts to assimilate returning Cuban-trained students will require a reframing of the current negative narrative by focusing on positive aspects of their training, orientation towards primary care and public health, and their aspirations to work in rural and under-served urban areas. Cuban-trained doctors could be part of the solution to South Africa's health workforce problems.

Adapting and Validating the Family Resilience Assessment Scale in an Afrikaans Rural Community in South Africa.

A family resilience framework understands families as having the potential to not only face adversities but to overcome them; although its measurement is not always agreed upon. The aim of this study is to explain the processes involved in the adaptation of the 54-item family resilience assessment scale into Afrikaans, and to further examine its psychometric properties. Data were collected via the door-to-door method with the assistance of fieldworkers in two rounds. The pilot sample included 82 participants whilst the larger study included 656 participants. The internal consistency and construct validity was assessed using Cronbach's alphas and Exploratory Factor Analysis implementing a Principal Component Analysis and Promax rotation, respectively. The factors which were found are similar to those of Sixbey's, however, a new factor emerged replacing Maintaining a positive outlook which was named Family and community outlook. The processes described in this study facilitated the assessment of the feasibility and efficiency of the full-scale study and reduced the number of unanticipated problems associated with large sample data collection particularly using fieldworkers.

Developmental Assets in South African Adolescents Exposed to Violence: a Qualitative Study on Resilience.

Violence exposure is associated with psychological and behavioural maladjustment in adolescents. Yet, not all adolescents exposed to violence experience negative symptoms. Resilience is an outcome that is in part determined by multiple protective factors, or developmental assets, that protect adolescents from the negative influence of encountered stressors and allow them to attain positive developmental outcomes. A qualitative study was conducted to acquire an in-depth understanding of the developmental assets across different layers in the ecological system that promote positive psychological and behavioural functioning in South African adolescents exposed to violence. Semi-structured individual interviews were conducted with a multi-ethnic group (black, white, and people of mixed heritage) of South African adolescents (boy: n = 17; girl: n = 13; age: 14-19 years) from seven schools in Cape Town. Adolescents reported both internal and external assets that helped them adaptively cope with violence exposure. The internal assets entailed individual characteristics and skills, including commitment to learning, positive values, positive identity, social competencies, and emotional insight. The external assets were boundaries and expectations, social support from adolescents' peers, family, school, and community, and adolescents' constructive use of time. The findings of the study may inform strengths-based interventions to enhance emotional and behavioural skills in adolescents at risk for violence exposure. Moreover, involving key stakeholders in the interventions from major developmental domains can be particularly helpful to optimise the social support that are needed for adolescents to be resilient.

Violence Exposure in South African Adolescents: Differential and Cumulative Effects on Psychological Functioning.

This study examined the associations between different types of violence victimization and psychological functioning in South African adolescents. Both differential and cumulative effects of violence were investigated. A multi-ethnic (Black, White, people of mixed heritage, and people of Indian/Asian descent) sample of adolescents in secondary schools in the Western Cape Province (N = 1,574; boys = 46.5%, girls = 53.5%; Mage = 16 years) completed a survey on their experiences of exposure to violence (across different contexts and polyvictimization) and their levels of hopelessness, anxiety, depression, perceived stress, and suicidal ideation. The results showed that indirect and direct victimization in the community, and indirect political victimization were consistent predictors for adverse psychological functioning, whereas victimization in home and school contexts did not emerge to be significant. Polyvictimization had a consistent linear effect on psychological symptoms. Interventions in South Africa should focus on addressing the psychological effects of community and political victimization on adolescents. Adopting a holistic treatment approach would be useful to gain a comprehensive understanding of adolescents' victimization experiences and maximize the impact of support to enhance their psychological functioning.

Exposure to violence across multiple contexts and health risk behaviours in South African adolescents: the moderating role of emotion dysregulation.

Objective: The association between violence exposure and health risk behaviours in South African adolescents, and the moderating role of emotion dysregulation were investigated. Design: A multi-ethnic sample of adolescents (N = 925: boy: 47.3%, girl: 52.7%, M age = 16 years, SD = 1.54) completed a survey. Main outcome measures: Violence exposure across different contexts (home-, school-, community-, political victimisation), emotion dysregulation (inability to regulate sadness and anger) and a composite measure of health risk behaviours (smoking, substance use, risky sexual behaviour) were examined. Results: Boys reported more risk behaviours than girls, t (844) = 5.25, p < 0.001. Direct community victimisation was a predictor for boys' risk behaviours, B = 0.22, p < 0.001. Indirect school victimisation and direct community victimisation were predictors for girls' risk behaviours, B's = 0.19, p's < 0.01. Girls reported higher emotion dysregulation than boys, t (748) = -2.95, p < 0.01. Only for girls, emotion dysregulation moderated the associations of indirect home victimisation, B = 16, p < 0.01, and direct community victimisation, B = 15, p < 0.05, with risk behaviours. Conclusion: Interventions may target emotion regulation skills, particularly for girls, to enhance resilience to the negative effects of violence on behaviours.

How recommender systems could support and enhance computer-tailored digital health programs: A scoping review.

OBJECTIVE: Tailored digital health programs can promote positive health-related lifestyle changes and have been shown to be (cost) effective in trials. However, such programs are used suboptimally. New approaches are needed to optimise the use of these programs. This paper illustrates the potential of recommender systems to support and enhance computer-tailored digital health interventions. The aim is threefold, to explore: (1) how recommender systems provide health recommendations, (2) to what extent recommender systems incorporate theoretical models and (3) how the use of recommender systems may enhance the usage of computer-tailored interventions. METHODS: A scoping review was conducted, using MEDLINE and ScienceDirect, to identify health recommender systems reported in studies between January 2007 and December 2017. Information was subsequently extracted to understand the potential benefits of recommender systems for computer-tailored digital health programs. Titles and abstracts of 1184 studies were screened for the full-text screening, in which two reviewers independently selected articles and systematically extracted data using a predefined extraction form. RESULTS: A total of 26 articles were included for data extraction. General characteristics were reported, with eight studies reporting hybrid filtering. A description of how each recommender system provides a recommendation is described; the majority of recommender systems used messages as recommendation. We identified the potential effects of recommender systems on efficiency, effectiveness, trustworthiness and enjoyment of the digital health program. CONCLUSIONS: Incorporating a collaborative method with demographic filtering as a second step to knowledge-based filtering could potentially add value to traditional tailoring with regard to enhancing the user experience. This study illustrates how recommender systems, especially hybrid programs, may have the potential to bring tailored digital health forward.
