    Boys are victims, too: the influence of perpetrators’ age and gender in sexual coercion against boys
    (SAGE Publications, 2018) Miller, Jacqueline A.; Smith, Edward A.; Caldwell, Linda L.; Mathews, Catherine; Wegner, Lisa
    Sexual coercion among adolescent boys in South Africa is an underresearched topic despite the frequency of such events. Although quantitative research has illuminated the prevalence of sexual coercion toward boys, it has provided little understanding of the context of sexual coercion for adolescent boys. Given the often severe consequences of sexual coercion, it is important to further understand these experiences to inform prevention efforts. The current study aims to provide a more nuanced understanding of the context of sexual coercion. Data come from the baseline assessment for a translational research evaluation of a school-based intervention. The current study focuses on a subset of early and middle adolescent boys who reported experiencing sexual coercion (n = 223). Analyses examine boys’ reports of their perpetrators’ characteristics and details about the sexual coercion encounter. Logistic regression is used to examine how coercion tactics used by the perpetrator differs depending on the perpetrator’s age and gender. Eighth-grade boys were most likely to report that their perpetrator was a similar-aged female and that perpetrator’s age played a particularly important role in what tactics were used. Adult perpetrators were more likely to use physical force, threaten them, harass them electronically, and drink or use drugs at the time. Results provide important insight into boys’ experiences of sexual coercion that have implications for both future research and intervention efforts. Although much research is needed on the topic, intervention programs should recognize that both male and female adolescents can be victim and perpetrator.

    The Feasibility of implementing a sexual risk reduction intervention in routine clinical practice at an ARV clinic in Cape Town: a case study
    (Springer, 2011) Dewing, Sarah; Mathews, Catherine; Schaay, Nikki; Cloete, Allanise; Simbayi, Leickness; Chopra, Mickey
    This case study with one lay adherence counsellor assessed the implementation of Options for Health, a sexual risk-reduction intervention based on Motivational Interviewing (MI), in an antiretroviral clinic in Cape Town, South Africa. In most cases Options was not delivered with fidelity and less than one-third of intended recipients received it; the counsellor often forgot to do Options, was unsure how to deal with particular cases and felt that there was not always time to do Options. Options was not implemented in a way that was consistent with MI. Revisions to the implementation plan and training programme are required.

    Forced sexual experiences and sexual situation self-efficacy among South African youth
    (Wiley, 2015) Miller, Jacqueline A.; Smith, Edward A.; Coffman, Donna; Mathews, Catherine; Wegner, Lisa
    Nearly 20% of South African youth experience forced or coerced sexual intercourse. Understanding the factors associated with forced sex is important for informing prevention programs aimed at reducing sexual violence and HIV and AIDS. Multilevel regression models test the association between sexual situation self-efficacy and forced sex among 2,893 South African adolescents. Findings suggest that youth are more likely to experience forced sex after periods of time when their levels of self-efficacy are lower than their average levels of self-efficacy. Furthermore, youth who are lower on their self-efficacy compared to their peers are more likely to experience forced sex. Implications for prevention research are discussed.

    From research to practice: Lay adherence counsellors' fidelity to an evidence-based intervention for promoting adherence to antiretroviral treatment in the Western Cape, South Africa
    (Springer Verlag, 2013) Dewing, Sarah; Mathews, Catherine; Cloete, Allanise; Schaay, Nikki; Shah, Madhvi; Simbayi, Leickness; Louw, Johann
    In the Western Cape, lay counsellors are tasked with supporting antiretroviral (ARV) adherence in public healthcare clinics. Thirty-nine counsellors in 21 Cape Town clinics were trained in Options for Health (Options), an evidence-based intervention based on motivational interviewing (MI). We evaluated counsellors’ ability to deliver Options for addressing poor adherence following 5 days training. Audio-recordings of counselling sessions collected following training were transcribed and translated into English. Thirty-five transcripts of sessions conducted by 35 counsellors were analysed for fidelity to the Options protocol, and using the Motivational Interviewing Treatment and Integrity (MITI) code. Counsellors struggled with some of the strategies associated with MI, such as assessing readiness-to-change and facilitating change talk. Overall, counsellors failed to achieve proficiency in the approach of MI according to the MITI. Counsellors were able to negotiate realistic plans for addressing patients’ barriers to adherence. Further efforts aimed at strengthening the ARV adherence counselling programme are needed.

    "It's important to take your medication everyday okay?" An evaluation of counselling by lay counsellors for ARV adherence support in the Western Cape, South Africa
    (Springer, 2013) Dewing, Sarah; Mathews, Catherine; Schaay, Nikki; Cloete, Allanise; Simbayi, Leickness; Louw, Johann
    There is growing interest in standard care programmes for antiretroviral (ARV) adherence support. In South Africa, individual counselling following ARV initiation is a main strategy for supporting adherence in the public sector. Egan’s client-centred ‘‘Skilled Helper’’ counselling model is the predominant model used in HIV counselling in this context. This study evaluated counselling delivered by lay ARV adherence counsellors in Cape Town in terms of adherence to Egan’s model. Thirty-eight transcripts of counselling sessions with non-adherent patients were analysed based on the methods of content analysis. These sessions were conducted by 30 counsellors. Generally counsellors’ practice adhered neither to Egan’s model nor a client-centred approach. Inconsistent with evidence-based approaches to counselling for ARV adherence support, counsellors mainly used informationgiving and advice as strategies for addressing clients’ nonadherence. Recommendations for improving practice are made. The question as to how appropriate strategies from developed countries are for this setting is also raised.

    Linking Life Skills and Norms with adolescent substance use and delinquency in South Africa
    (National Institute of Health, 2013) Lai, Mary H.; Graham, John W.; Caldwell, Linda L.; Smith, Edward A.; Bradley, Stephanie A.; Mathews, Catherine; Vergnani, Tania; Wegner, Lisa
    We examined factors targeted in two popular prevention approaches with adolescent drug use and delinquency in South Africa. We hypothesized adolescent life skills to be inversely related, and perceived norms to be directly related to later drug use and delinquency. Multiple regression and a relative weights approach were conducted for each outcome using a sample of 714 South African adolescents ages 15 to 19 years (M = 15.8 years, 57% female). Perceived norms predicted gateway drug use. Conflict resolution skills (inversely) and perceived peer acceptability (directly) predicted harder drug use and delinquency. The “culture of violence” within some South African schools may make conflict resolution skills more salient for preventing harder drug use and delinquency.

    Predicting substance use behavior among South African adolescents: The role of leisure experiences across time
    (SAGE Publications, 2011) Sharp, Erin Hiley; Coffman, Donna; Caldwell, Linda L.; Smith, Edward A.; Wegner, Lisa; Vergnani, Tania; Mathews, Catherine
    Using seven waves of data, collected twice a year from the 8th through the 11th grades in a low-resource community in Cape Town, South Africa, we aimed to describe the developmental trends in three specific leisure experiences (leisure boredom, new leisure interests, and healthy leisure) and substance use (cigarettes, alcohol, and marijuana) behaviors and to investigate the ways in which changes in leisure experiences predict changes in substance use behaviors over time. Results indicated that adolescents’ substance use increased significantly across adolescence, but that leisure experiences remained fairly stable over time. We also found that adolescent leisure experiences predicted baseline substance use and that changes in leisure experiences predicted changes in substance use behaviors over time, with leisure boredom emerging as the most consistent and strongest predictor of alcohol, cigarette, and marijuana use. Implications for interventions that target time use and leisure experiences are discussed.

    Translational research in South Africa: evaluating implementation quality using a factorial design
    (Springer Verlag, 2012) Caldwell, Linda L.; Smith, Edward A.; Collins, Linda M.; Graham, John W.; Lai, Mary H.; Wegner, Lisa; Vergnani, Tania; Mathews, Catherine; Jacobs, Joachim
    Background: HealthWise South Africa: Life Skills for Adolescents (HW) is an evidence- based substance use and sexual risk prevention program that emphasizes the positive use of leisure time. Since 2000, this program has evolved from pilot testing through an efficacy trial involving over 7,000 youth in the Cape Town area. Beginning in 2011, through 2015, we are undertaking a new study that expands HW to all schools in the Metro South Education District. Objective: This paper describes a research study designed in partnership with our South African collaborators that examines three factors hypothesized to affect the quality and fidelity of HW implementation: enhanced teacher training; teacher support, structure and supervision; and enhanced school environment. Methods: Teachers and students from 56 schools in the Cape Town area will participate in this study. Teacher observations are the primary means of collecting data on factors affecting implementation quality. These factors address the practical concerns of teachers and schools related to likelihood of use and cost-effectiveness, and are hypothesized to be "active ingredients" related to high-quality program implementation in real-world settings. An innovative factorial experimental design was chosen to enable estimation of the individual effect of each of the three factors. Results: Because this paper describes the conceptualization of our study, results are not yet available. Conclusions: The results of this study may have both substantive and methodological implications for advancing Type 2 translational research.

    Validation of simple dichotomous self-report on prenatal alcohol and other drug use in women attending midwife obstetric units in the Cape Metropole, South Africa
    (SAGE, 2020) Williams, Petal Petersen; Mathews, Catherine; Jordaan, Esmé R
    Background: This paper examines the degree of agreement among simple dichotomous self-report, validated screening results, and biochemical screening results of prenatal alcohol and other drug use among pregnant women. Method: Secondary analysis was conducted on a cohort of pregnant women 16 years or older, presenting for prenatal care in the greater Cape Town, South Africa. Dichotomous verbal screening is a standard of care, and pregnant patients reporting alcohol and other drug use in dichotomous verbal screenings were asked to engage in screening using the Alcohol Smoking and Substance Involvement Screening Test (ASSIST) and urinalysis.
