A Behavior-Based Intervention That Prevents Sexual Assault: the Results of a Matched-Pairs, Cluster-Randomized Study in Nairobi, Kenya.

ABSTRACT: DESIGN:The study's design was a cluster-randomized, matched-pairs, parallel trial of a behavior-based sexual assault prevention intervention in the informal settlements. METHODS:The participants were primary school girls aged 10-16. Classroom-based interventions for girls and boys were delivered by instructors from the same settlements, at the same time, over six 2-h sessions. The girls' program had components of empowerment, gender relations, and self-defense. The boys' program promotes healthy gender norms. The control arm of the study received a health and hygiene curriculum. The primary outcome was the rate of sexual assault in the prior 12 months at the cluster level (school level). Secondary outcomes included the generalized self-efficacy scale, the distribution of number of times victims were sexually assaulted in the prior period, skills used, disclosure rates, and distribution of perpetrators. Difference-in-differences estimates are reported with bootstrapped confidence intervals. RESULTS:Fourteen schools with 3147 girls from the intervention group and 14 schools with 2539 girls from the control group were included in the analysis. We estimate a 3.7 % decrease, p?=?0.03 and 95 % CI?=?(0.4, 8.0), in risk of sexual assault in the intervention group due to the intervention (initially 7.3 % at baseline). We estimate an increase in mean generalized self-efficacy score of 0.19 (baseline average 3.1, on a 1-4 scale), p?=?0.0004 and 95 % CI?=?(0.08, 0.39). INTERPRETATION:This innovative intervention that combined parallel training for young adolescent girls and boys in school settings showed significant reduction in the rate of sexual assault among girls in this population.

Project description:BackgroundSexual violence against adolescents is prevalent worldwide and results in significant physical and mental injuries as well as loss of economic and personal potential. Urban informal settlements such as those around Nairobi, Kenya have been shown to have especially high incidences of violence. Research has shown that empowerment interventions for female adolescents can reduce sexual assault. However, these interventions have had limited testing in urban informal settlements, with young adolescents, or in coordination with complementary programs for male adolescents.Methods/designThis study was a two-arm, parallel, cluster-randomized trial testing a combination of a previously-tested girls' intervention, IMPower, and a newly revised boys' intervention, Source of Strength. Clusters were defined as schools within the informal settlements; participants were adolescent girls and boys in class 6, generally between the ages of 10-14 at baseline. Data collection began in January 2016 and continued through December 2018. The primary outcome was the change in incidence of self-reported sexual assault among girls from baseline, compared to a life skills standard of care intervention. Secondary outcomes included experiences of physical and emotional violence, as well as determining the effects of the intervention on self-efficacy, self-esteem, and gender attitudes and beliefs, and how those effects led to changes in experience of sexual assault. For the primary outcome and several of the secondary outcomes, we used an intention to treat estimand.DiscussionThis was the first randomized controlled trial with longitudinal follow-up of an empowerment self-defense approach to violence prevention for adolescents in informal settlements. The large size and rigorous design supported analysis to understand multiple subgroup experiences in the hypothesized reduction in sexual assault. The study was also unique in its focus on young (10-14 years of age) adolescents and in engaging both boys and girls in separate but coordinated curriculums. The focus on a highly vulnerable and understudied population will make it a significant contribution to the literature on violence prevention.Trial registrationClinical Trials.gov # NCT02771132 .

Project description:BackgroundReproductive coercion (RC) and intimate partner violence (IPV) are prevalent forms of gender-based violence (GBV) associated with reduced female control over contraceptive use and subsequent unintended pregnancy. Although the World Health Organization has recommended the identification and support of GBV survivors within health services, few clinic-based models have been shown to reduce IPV or RC, particularly in low or middle-income countries (LMICs). To date, clinic-based GBV interventions have not been shown to reduce RC or unintended pregnancy in LMIC settings.InterventionARCHES (Addressing Reproductive Coercion in Health Settings) is a single-session, clinic-based model delivered within routine contraceptive counseling that has been demonstrated to reduce RC in the United States. ARCHES was adapted to the Kenyan context via a participatory process to reduce GBV and unintended pregnancy among women and girls seeking contraceptive services in this setting. Core elements of ARCHES include enhanced contraceptive counseling that addresses RC, opportunity for patient disclosure of RC and IPV (and subsequent warm referral to local services), and provision of a palm-sized educational booklet.MethodsA matched-pair cluster control trial is being conducted to assess whether the ARCHES intervention (treatment condition), as compared to standard-of-care contraceptive counseling (control condition), reduces RC and IPV, and improves contraceptive outcomes for woman and girls of reproductive age (15 to 49 years) seeking contraceptive services from community-based clinics in Nairobi, Kenya. All six clinics were assigned to intervention-control pairs based on similarities in patient volume and demographics, physical structure and neighborhood context. Survey data will be collected from patients immediately prior to their clinic visit (baseline, T1), immediately after their clinic visit (exit), and at 3- and 6-months post-visit (T2 and T3, respectively).DiscussionThis study is the first to assess the efficacy of an adaptation of the ARCHES model to reduce GBV and improve reproductive health outside of the U.S., and one of only a small number of controlled trials to assess reductions in GBV associated with a clinic-based program in an LMIC context. Evidence from this trial will inform health system efforts to reduce GBV, and to enhance female contraceptive control and reproductive health in Kenya and globally.Trial registrationRegistered May 23, 2018 - ClinicalTrials.gov, NCT03534401.

Project description:BackgroundMobile technology can support HIV care, but studies in youth are limited. In 2014, youth receiving HIV care at several health care facilities in Nairobi, Kenya spontaneously formed peer support groups using the social media platform WhatsApp.ObjectiveInspired by youth-initiated groups, we aimed to evaluate the use of WhatsApp to deliver a social support intervention to improve HIV treatment and psychosocial outcomes in youth. We developed a facilitated WhatsApp group intervention (named Vijana-SMART), which was grounded in social support theory and guided by the design recommendations of youth living with HIV. This paper evaluates the intervention's acceptability and pre-post changes in health outcomes.MethodsThe intervention involved interactive WhatsApp groups facilitated by study staff for 6 months, with each group having approximately 25 members. Study staff sent weekly structured messages, and the message content was based on social support theory and encouraged unstructured peer-to-peer messaging and support. We conducted a single-arm pilot among 55 youth living with HIV aged 14-24 years recruited from a government health care facility serving a mixed-income area of Nairobi. At enrollment and follow-up, self-report questionnaires assessed acceptability; antiretroviral therapy (ART) information, motivation, and behavioral skills (IMB); depression; social support; stigma; resilience; and ART adherence. All participants received the intervention. We used generalized estimating equations (GEEs) clustered by participant to evaluate changes in scores from baseline to follow-up, and correlates of participant WhatsApp messaging.ResultsThe median participant age was 18 years, and 67% (37/55) were female. Intervention acceptability was high. All participants reported that it was helpful, and 73% (38/52) sent ≥1 WhatsApp message. Messaging levels varied considerably between participants and were higher during school holidays, earlier in the intervention period, and among youth aged ≥18 years. IMB scores increased from enrollment to follow-up (66.9% to 71.3%; P<.001). Stigma scores also increased (8.3% to 16.7%; P=.001), and resilience scores decreased (75.0% to 70.0%; P<.001). We found no significant change in ART adherence, social support, or depression. We detected a positive association between the level of messaging during the study and the resilience score, but no significant association between messaging and other outcomes. Once enrolled, it was common for participants to change their phone numbers or leave the groups and request to be added back, which may present implementation challenges at a larger scale.ConclusionsIncreased IMB scores following WhatsApp group participation may improve HIV outcomes. Increased stigma and decreased resilience were unintended consequences and may reflect transient effects of group sharing of challenging experiences, which should be addressed in larger randomized evaluations. WhatsApp groups present a promising and acceptable modality to deliver supportive interventions to youth living with HIV beyond the clinic, and further evaluation is warranted.Trial registrationClinicalTrials.gov (NCT05634265); https://clinicaltrials.gov/study/NCT05634265.
