Health diplomacy and the adaptation of global health interventions to local needs in sub-Saharan Africa and Thailand: evaluating findings from Project Accept (HPTN 043).

BACKGROUND: Study-based global health interventions, especially those that are conducted on an international or multi-site basis, frequently require site-specific adaptations in order to (1) respond to socio-cultural differences in risk determinants, (2) to make interventions more relevant to target population needs, and (3) in recognition of 'global health diplomacy' issues. We report on the adaptations development, approval and implementation process from the Project Accept voluntary counseling and testing, community mobilization and post-test support services intervention. METHODS: We reviewed all relevant documentation collected during the study intervention period (e.g. monthly progress reports; bi-annual steering committee presentations) and conducted a series of semi-structured interviews with project directors and between 12 and 23 field staff at each study site in South Africa, Zimbabwe, Thailand and Tanzania during 2009. Respondents were asked to describe (1) the adaptations development and approval process and (2) the most successful site-specific adaptations from the perspective of facilitating intervention implementation. RESULTS: Across sites, proposed adaptations were identified by field staff and submitted to project directors for review on a formally planned basis. The cross-site intervention sub-committee then ensured fidelity to the study protocol before approval. Successfully-implemented adaptations included: intervention delivery adaptations (e.g. development of tailored counseling messages for immigrant labour groups in South Africa) political, environmental and infrastructural adaptations (e.g. use of local community centers as VCT venues in Zimbabwe); religious adaptations (e.g. dividing clients by gender in Muslim areas of Tanzania); economic adaptations (e.g. co-provision of income generating skills classes in Zimbabwe); epidemiological adaptations (e.g. provision of 'youth-friendly' services in South Africa, Zimbabwe and Tanzania), and social adaptations (e.g. modification of terminology to local dialects in Thailand: and adjustment of service delivery schedules to suit seasonal and daily work schedules across sites). CONCLUSIONS: Adaptation selection, development and approval during multi-site global health research studies should be a planned process that maintains fidelity to the study protocol. The successful implementation of appropriate site-specific adaptations may have important implications for intervention implementation, from both a service uptake and a global health diplomacy perspective.

HIV-related stigma, social norms, and HIV testing in Soweto and Vulindlela, South Africa: National Institutes of Mental Health Project Accept (HPTN 043).

OBJECTIVE: HIV testing is necessary to curb the increasing epidemic. However, HIV-related stigma and perceptions of low likelihood of societal HIV testing may reduce testing rates. This study aimed to explore this association in South Africa, where HIV rates are extraordinarily high. METHODS: Data were taken from the Soweto and Vulindlela, South African sites of Project Accept, a multinational HIV prevention trial. Self-reported HIV testing, stigma, and social norms items were used to study the relationship between HIV testing, stigma, and perceptions about societal testing rates. The stigma items were broken into 3 factors: negative attitudes, negative perceptions about people living with HIV, and perceptions of fair treatment for people living with HIV (equity). RESULTS: Results from a univariate logistic regression suggest that history of HIV testing was associated with decreased negative attitudes about people living with HIV/AIDS, increased perceptions that people living with HIV/AIDS experience discrimination, and increased perceptions that people with HIV should be treated equitably. Results from a multivariate logistic regression confirm these effects and suggest that these differences vary according to sex and age. Compared with people who had never tested for HIV, those who had previously tested were more likely to believe that the majority of people have tested for HIV. CONCLUSIONS: Data suggest that interventions designed to increase HIV testing in South Africa should address stigma and perceptions of societal testing.

A comparison of HIV/AIDS-related stigma in four countries: negative attitudes and perceived acts of discrimination towards people living with HIV/AIDS.

HIV/AIDS-related stigma and discrimination have a substantial impact on people living with HIV/AIDS (PLHA). The objectives of this study were: (1) to determine the associations of two constructs of HIV/AIDS-related stigma and discrimination (negative attitudes towards PLHA and perceived acts of discrimination towards PLHA) with previous history of HIV testing, knowledge of antiretroviral therapies (ARVs) and communication regarding HIV/AIDS and (2) to compare these two constructs across the five research sites with respect to differing levels of HIV prevalence and ARV coverage, using data presented from the baseline survey of U.S. National Institute of Mental Health (NIMH) Project Accept, a four-country HIV prevention trial in Sub-Saharan Africa (Tanzania, Zimbabwe and South Africa) and northern Thailand. A household probability sample of 14,203 participants completed a survey including a scale measuring HIV/AIDS-related stigma and discrimination. Logistic regression models determined the associations between negative attitudes and perceived discrimination with individual history of HIV testing, knowledge of ARVs and communication regarding HIV/AIDS. Spearman's correlation coefficients determined the relationships between negative attitudes and perceived discrimination and HIV prevalence and ARV coverage at the site-level. Negative attitudes were related to never having tested for HIV, lacking knowledge of ARVs, and never having discussed HIV/AIDS. More negative attitudes were found in sites with the lowest HIV prevalence (i.e., Tanzania and Thailand) and more perceived discrimination against PLHA was found in sites with the lowest ARV coverage (i.e., Tanzania and Zimbabwe). Programs that promote widespread HIV testing and discussion of HIV/AIDS, as well as education regarding and universal access to ARVs, may reduce HIV/AIDS-related stigma and discrimination.

A comparison of HIV stigma and discrimination in five international sites: the influence of care and treatment resources in high prevalence settings.

What accounts for differences in HIV stigma across different high prevalence settings? This study was designed to examine HIV stigma and discrimination in five high prevalence settings. Qualitative data were collected as part of the U.S. National Institute of Mental Health (NIMH) Project Accept, a multi-site community randomized trial of community-based HIV voluntary counseling and testing. In-depth interviews were conducted with 655 participants in five sites, four in Sub-Saharan Africa and one in Southeast Asia. Interviews were conducted in the local languages by trained research staff. Data were audiotaped, transcribed, translated, coded and computerized for thematic data analysis. Participants described the stigmatizing attitudes and behaviors perpetuated against people living with HIV/AIDS (PLWHA). The factors that contribute to HIV stigma and discrimination include fear of transmission, fear of suffering and death, and the burden of caring for PLWHA. The family, access to antiretrovirals and other resources, and self-protective behaviors of PLWHA protected against HIV stigma and discrimination. Variation in the availability of health and socioeconomic resources designed to mitigate the impact of HIV/AIDS helps explain differences in HIV stigma and discrimination across the settings. Increasing access to treatment and care resources may function to lower HIV stigma, however, providing services is not enough. We need effective strategies to reduce HIV stigma as treatment and care resources are scaled up in the settings that are most heavily impacted by the HIV epidemic.

Test and tell: correlates and consequences of testing and disclosure of HIV status in South Africa (HPTN 043 Project Accept).

BACKGROUND: As the numbers of HIV-positive diagnoses rise in South Africa, it is important to understand the determinants and consequences of HIV disclosure. METHODS: Cross-sectional survey from random community samples of men and women in urban and rural South Africa (n = 217 HIV-positive individuals, 89% female). RESULTS: Two thirds of all known HIV-infected adults in these communities had disclosed their status to sexual partner(s). On average, individuals who disclosed were 2 years older, higher in socioeconomic assets, and had known their HIV status 7 months longer than those who had not told their sexual partner(s). The "need for privacy" was the most cited reason (45%) for nondisclosure among those who had never disclosed. People who eventually disclosed their HIV status to sexual partner(s) were significantly more likely to report always or more frequently using condoms, reducing their number of sexual partners, and/or becoming monogamous. Among individuals who disclosed their HIV status, 77% reported increases in social support, with families providing the most support. CONCLUSIONS: Disclosure is associated with reports of consequent safer sexual behavior and greater social support. Interventions might be informed by the costs and benefits of disclosure and differences in disclosure to sexual partner vs. to one's social network.

Using participatory mapping to inform a community-randomized trial of HIV counseling and testing.

Participatory mapping and transect walks were used to inform the research and intervention design and to begin building community relations in preparation for Project Accept, a community-randomized trial sponsored by the U.S. National Institute of Mental Health (NIMH). NIMH Project Accept is being conducted in five sites within four countries including Thailand, Zimbabwe, South Africa and Tanzania. Results from the mapping exercises informed decisions about the research design such as defining community boundaries, and identifying appropriate criteria for matching community pairs for the trial. The mapping also informed intervention related decisions such as where to situate the services. The participatory methods enabled each site to develop an understanding of the communities that could not have been derived from existing data or data collected through standard data collection techniques. Furthermore, the methods lay the foundation for collaborative community research partnerships.

Project Accept (HPTN 043): a community-based intervention to reduce HIV incidence in populations at risk for HIV in sub-Saharan Africa and Thailand.

BACKGROUND: Changing community norms to increase awareness of HIV status and reduce HIV-related stigma has the potential to reduce the incidence of HIV-1 infection in the developing world. METHODS: We developed and implemented a multilevel intervention providing community-based HIV mobile voluntary counseling and testing, community mobilization, and posttest support services. Forty-eight communities in Tanzania, Zimbabwe, South Africa, and Thailand were randomized to receive the intervention or clinic-based standard voluntary counseling and testing (VCT), the comparison condition. We monitored utilization of community-based HIV mobile voluntary counseling and testing and clinic-based standard VCT by community of residence at 3 sites, which was used to assess differential uptake. We also developed quality assurance procedures to evaluate staff fidelity to the intervention. FINDINGS: In the first year of the study, a 4-fold increase in testing was observed in the intervention versus comparison communities. We also found an overall 95% adherence to intervention components. Study outcomes, including prevalence of recent HIV infection and community-level HIV stigma, will be assessed after 3 years of intervention. CONCLUSIONS: The provision of mobile services, combined with appropriate support activities, may have significant effects on utilization of voluntary counseling and testing. These findings also provide early support for community mobilization as a strategy for increasing testing rates.

HIV risk behaviors in sub-Saharan Africa and Northern Thailand: baseline behavioral data from Project Accept.

BACKGROUND: Of 2.5 million new HIV infections worldwide in 2007, most occurred in sub-Saharan Africa and southeast Asia. We present the baseline data on HIV risk behaviors and HIV testing in sub-Saharan Africa and northern Thailand from Project Accept, a community-randomized controlled trial of community mobilization, mobile voluntary counseling and testing (VCT), and posttest support services. METHODS: A random household probability sample of individuals aged 18-32 years yielded a sample of 14,657, with response rates ranging from 84%-94% across the 5 sites (Thailand, Zimbabwe, Tanzania, and 2 in South Africa). Individuals completed an interviewer-administered survey on demographic characteristics, HIV risk behaviors, and history of VCT. RESULTS: In multivariate analysis, females, married individuals, less educated with 1 sexual partner in the past 6 months were more likely to have had unprotected intercourse in the previous 6 months. Rates of lifetime HIV testing ranged from 5.4% among males in Zimbabwe to 52.6% among females in Soweto. CONCLUSIONS: Significant risk of HIV acquisition in Project Accept communities exists despite 2 decades of prevention efforts. Low levels of recent HIV testing suggest that increasing awareness of HIV status through accessible VCT services may reduce HIV transmission.

Profile of Community Mental Health Service Needs in the Moretele District (North-West Province) in South Africa.

BACKGROUND: The emergence of democracy in South Africa led to a need to transform all public structures, including the health care system. The aim has been to transform these structures in order to bring them in line with the new culture of human rights. Transformation of the whole health care system is motivated by a number of key objectives, which include achieving equity in resource allocation and health service delivery, developing primary health care infrastructure and decentralising services to promote community participation. AIMS OF THE STUDY: In the context of de-institutionalising mental health services in South Africa, this study aimed to investigate community mental health service needs of mental health service users and that of their families in the Moretele district, North-West province, South Africa. METHODS: The study was conducted in three clinics situated in three different communities in the Moretele district. Data collection consisted of : 147 clinical record reviews, 105 interviews with patients followed by a joint interview with a family member, 83 interviews with caregivers and eight interviews with community key informants (traditional healers, a civic leader, a councillor, a retired teacher, and a physician). RESULTS: The majority of service users were males (54%). The mean age was 41 years and 63% had completed primary schooling.Patients were recorded as having only one of two primary diagnoses, namely schizophrenia (57%) or epilepsy (41%). However, a review of prescribed drugs and caregiver interviews showed that there was a presence of mood disorders among service users. The local hospital was service users primary entry point into the mental health care system, followed by traditional healers (30%). Interviews with service users, service providers and caregivers reveal limited knowledge of patient illness. Nevertheless, service users who had epilepsy were more likely to provide details of their illness than those with mental illness. Above half of service users had basic social skills such as bathing, eating, washing and using public transportation independently. Feelings of loneliness and isolation were common among service users in the community; seventy nine percent (79%), for example spent their days entirely in their homes. Only 7% reported contact with friends. Experiences of community discrimination and exploitation of people with mental illness were reported in key informant interviews and by service users themselves. DISCUSSION: The main community mental health service needs identified in this study were: (i) Improved quality of mental health services at clinics. (ii) Better co-ordination of services (clinic, hospital, social work and traditional healers) and removal of barriers to health service utilisation. (iii) Alleviation of the social isolation of mental health service users by building on existing community structures and individuals willing to engage in partnerships with service providers. The authors indentify a need to train primary health care providers in mental health in order to promote the adequate diagnosis and detection of common psychiatric illnesses.They also point out the need for social support interventions to enable people with mental illness to deal with loneliness and isolation and a need for psycho-educational programmes to make patients and caregivers better informed about mental illness.
