Abstract
Receiving peer advocacy has been shown to result in increased HIV protective behaviors, but little research has gone beyond assessment of the mere presence of advocacy to examine aspects of advocacy driving these effects. With baseline data from a controlled trial of an advocacy training intervention, we studied characteristics of HIV prevention advocacy received among 599 social network members of persons living with HIV in Uganda and the association of these characteristics with the social network members' recent HIV testing (past six months) and consistent condom use, as well as perceived influence of advocacy on these behaviors. Participants reported on receipt of advocacy specific to HIV testing and condom use, as well as on measures of advocacy content, tone of delivery, support for autonomous regulation, and perceived influence on behavior. Receiving HIV testing advocacy and condom use advocacy were associated with recent HIV testing [65.2% vs. 51.4%; OR (95% CI) = 1.77 (1.11-2.84)], and consistent condom use with main sex partner [19.3% vs. 10.0%; OR (95% CI) = 2.16 (1.12-4.13)], respectively, compared to not receiving advocacy. Among those who received condom advocacy, perceived influence of the advocacy was positively correlated with consistent condom use, regardless of type of sex partner; support of autonomous regulation was a correlate of consistent condom use with casual sex partners, while judgmental advocacy was a correlate of consistent condom use with serodiscordant main partners. Among those who received testing advocacy, HIV testing in the past 6 months was positively correlated with receipt of direct support for getting tested. In multiple regression analysis, perceived influence of both HIV testing and condom use advocacy were positively correlated with advocacy that included access information and support of autonomous regulation; confrontational advocacy and judgmental advocacy were independent positive correlates of perceived influence of testing and condom use advocacy, respectively. These findings support associations that suggest potential benefits of peer advocacy from PLWH on HIV testing and condom use among their social network members, and indicate that advocacy content, tone of delivery, and support of autonomous regulation advocacy may play an important role in the success of advocacy.

Association of Condom Use Advocacy with Perceived Condom Use Among Social Network Members: The Mediating Role of Advocates' Internalized HIV Stigma and Own Condom Use. AIDS Behav 2022; 26:2485-2493. [PMID: 35091879 DOI: 10.1007/s10461-022-03601-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/21/2022] [Indexed: 11/01/2022]
Abstract
We examined the association of HIV prevention advocacy with social network members (alters) on alter condom use behavior, and factors that may mediate and moderate this relationship, among people living with HIV (PLWH) in Uganda. Ninety PLWH completed all assessments (baseline and 5- and 8-month follow-ups). Internalized HIV stigma, HIV disclosure self-efficacy, positive living behavior (i.e., condom use), and advocacy self-efficacy were examined as mediators (at 5-month follow-up) of the association between condom use advocacy and perceived alter condom use. Individual socio-demographic and social network characteristics at baseline were examined as moderators. Among alters who received condom use advocacy in the months prior to both baseline and 5-month follow-up, 69.9% (51/73) were perceived to mostly/always use condoms at either the 5- or 8-month follow-up, which was significantly higher than the 36.4% (235/645) of alters who received none or less advocacy. Participants' internalized HIV stigma and consistent condom use mediated the association of advocacy and perceived consistent condom use among alters; the participant having any secondary education and the alter being male were associated with increased magnitude of the associations between advocacy and alter condom use. These findings highlight the importance of sustained advocacy to promote consistent condom use, and the value of anti-stigma and positive living interventions as mechanisms for enhancing effective advocacy.

Abstract
INTRODUCTION Innovative strategies are needed to disseminate HIV prevention messages across communities efficiently, as well as reduce HIV stigma while promoting HIV prevention. This randomized controlled trial will evaluate the efficacy of a social network-based group intervention, Game Changers, which trains persons living with HIV (PLWH) to encourage members of their social network to use HIV protective behaviors METHODS: PLWH in HIV care for at least 1 year will be randomly assigned to receive the 8-session group advocacy training intervention or no-intervention control group. Each enrolled PLWH (index participant) will be asked to recruit up to four social network members (alter participant). Assessments will be administered at baseline and months 6, 12, and 18 to both index and alter participants. The primary outcomes are HIV testing and condom use among alter participants; secondary outcomes are engagement in HIV prevention advocacy and internalized HIV stigma among index participants. Repeated-measures multivariable regression analyses will be conducted to compare outcomes between the intervention and control arms, in addition to a cost-effectiveness evaluation. DISCUSSION This social network-based approach to HIV prevention is particularly timely in the era of biomedical interventions, which require widespread penetration of effective HIV prevention and care messaging into communities. Positioning PLWH as central to the solution for controlling (vs. causing) the HIV epidemic has the potential to reduce HIV stigma and improve prevention outcomes at the individual and network levels.

Examination of Mediators and Moderators to Understand How and in What Context Game Changers Increases HIV Prevention Advocacy Among Persons Living With HIV in Uganda. Int J Behav Med 2021; 28:737-745. [PMID: 33791991 PMCID: PMC8481355 DOI: 10.1007/s12529-021-09983-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/22/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Our randomized controlled trial (RCT) of the group-based Game Changers intervention demonstrated effects on the primary goal of increased HIV-protective behaviors among social network members (alters), via the mechanism of increased participant engagement in HIV prevention advocacy with alters. We sought to understand how and in what context the intervention has its effects by examining specific mediators and moderators of the intervention's effect on increased prevention advocacy. METHODS The RCT was conducted with 98 adult PLWH in Uganda. Intervention content targeted internalized HIV stigma, HIV disclosure, positive living behaviors, and self-efficacy for advocacy; these constructs were examined as intervention mediators (at the 5-month follow-up) of advocacy effects reported at the 8-month follow-up. Baseline sample characteristics were explored as moderators. RESULTS Internalized HIV stigma and HIV disclosure mediated intervention effects on prevention advocacy, but not antiretroviral adherence or self-efficacy for advocacy. Moderators of the intervention effect included several network characteristics (trust in, support from, stigma from, and connectedness among network members), but not respondent socio-demographics or HIV disease characteristics. The intervention was associated with greater prevention advocacy when trust in, support from, and connectedness among alters were high, and stigma from alters was low. CONCLUSIONS These findings highlight the importance of helping PLWH cope with self-stigma and gain comfort with disclosure, as well as the potential influence of network support, trustworthiness, connectedness, and stigmatization on engagement in prevention advocacy.

Abstract
INTRODUCTION Communities exert stigma on mothers after stillbirth despite their potential to offer social support to the grieving family. Maternal healthcare-seeking behaviors are socially reinforced rendering a social network approach vital in understanding support dynamics which when utilized can improve community response to mothers experiencing stillbirth. However, the form and direction of social support for women when in need is not clear. The study explored the role and attributes of women's social networks in the provision of support to mothers who have experienced a stillbirth in Uganda. METHODS An exploratory cross-sectional study design adopting a social network approach was conducted. Data collection following established procedures was conducted on a convenient sample of 17 mothers who had experienced a stillbirth six months before the study. Frequencies and bivariate analysis were conducted to determine the factors influencing the provision of social support from 293 network members elicited during the alter generation. We then performed a Poisson regression on each of the social support forms and the explanatory variables. Network structure variables were calculated using UCINET version 6 while Netdraw facilitated the visualization of networks. RESULTS Overall, social support was available from all network relations mentioned by the respondents. No major variations were observed between the two time periods during pregnancy and following a stillbirth. The most common support received was in form of intangible support such as emotional and information support, mainly from females who were married and from the naturally occurring networks such as family and friends. We also observed that social support followed patterns of network relational characteristics including trust, frequency of contact and alters counted on for support more likely to provide the same. CONCLUSIONS A great potential for social support exists within women's social networks to help address stillbirth risk factors during pregnancy and cope after experiencing the same. Alter characteristics like being female, married, and from naturally occurring networks together with relational characteristics such as trust, frequency of contact, and count on alter for support were predictors of eventual social support. Interventions aiming at addressing stillbirth risks at the community level ought to harness these network characteristics for benefits to the mothers.

Abstract
Interest in conceptualizing, measuring, and applying social network analysis (SNA) in public health has grown tremendously in recent years. While these studies have broadened our understanding of the role that social networks play in health, there has been less research that has investigated the application of SNA to inform health-related interventions. This systematic review aimed to capture the current applied use of SNA in the development, dissemination, implementation, and sustainability of health behavior interventions for adults. We identified 52 articles published between 2004 and 2016. A wide variety of study settings were identified, most commonly in the US context and most often related to sexual health and HIV prevention. We found that 38% of articles explicitly applied SNA to inform some aspect of interventions. Use of SNA to inform intervention development (as opposed to dissemination, implementation, or sustainability) was most common. The majority of articles represented in this review (n = 39) were quantitative studies, and 13 articles included a qualitative component. Partial networks were most represented across articles, and over 100 different networks measures were assessed. The most commonly described measures were network density, size, and degree centrality. Finally, very few articles defined SNA and not all articles using SNA were theoretically-informed. Given the nascent and heterogeneous state of the literature in this area, this is an important time for the field to coalesce on terminology, measures, and theoretical frameworks. We highlight areas for researchers to advance work on the application of SNA in the design, dissemination, implementation and sustainability of behavioral interventions.

Abstract
OBJECTIVES To explore acceptability of recruiting social contacts for HIV and sexually transmitted infection (STI) screening in Lilongwe, Malawi. METHODS In this observational study, three groups of 'seed' patients were enrolled: 45 HIV-infected patients with STI, 45 HIV-uninfected patients with STI and 45 community controls, who were also tested for HIV as part of the study. Each seed was given five coupons and asked to recruit up to five social contacts to the STI clinic. Seeds were told the programme for contacts would include HIV testing, STI screening and general health promotion. Seeds were asked to return after 1 month to report on the contact recruitment process. Seeds received $2 for each successfully recruited contact. RESULTS Eighty-nine seeds (66%) returned for 1-month follow-up with no difference between the three seed groups (p=0.9). Returning seeds reported distributing most of their coupons (mean=4.1) and discussing each feature of the programme with most contacts-HIV testing (90%), STI screening (87%) and health promotion (91%). Seeds reported discussing their own HIV status with most contacts (52%), with a lower proportion of HIV-infected seeds discussing their HIV status (22%) than HIV-uninfected seeds (81%) or community seeds (64%) (p<0.001). Contact recruitment did not vary with socioeconomic status. CONCLUSIONS Most seeds distributed all coupons and reported describing all aspects of the programme to most contacts. Patients with STI are able to act as health promoters within their social networks and may be a critical link to increasing STI and HIV status awareness among high-risk groups.

Abstract
We examined how functional social support, HIV-related discrimination, internalized HIV stigma, and social network structure and composition were cross-sectionally associated with network members' knowledge of respondents' serostatus among 244 HIV-positive African Americans in Los Angeles. Results of a generalized hierarchical linear model indicated people in respondents' networks who were highly trusted, well-known to others (high degree centrality), HIV-positive, or sex partners were more likely to know respondents' HIV serostatus; African American network members were less likely to know respondents' serostatus, as were drug-using partners. Greater internalized stigma among respondents living with HIV was associated with less knowledge of their seropositivity within their social network whereas greater respondent-level HIV discrimination was associated with more knowledge of seropositivity within the network. Additional research is needed to understand the causal mechanisms and mediating processes associated with serostatus disclosure as well as the long-term consequences of disclosure and network members' knowledge of respondents' serostatus.

Abstract
Personal social networks and their association with the health of older people have been explored, but there are few studies that examined the relationship between the general health of older people living with HIV/AIDS (OPLWHA) and their personal social networks. This exploratory study investigates the characteristics of personal networks among OPLWHA and the relationship between the self-rated health and personal social networks of OPLWHA in Lomé, Togo. Forty-nine OPLWHA were interviewed via an egocentric survey. We examined the composition and size of the networks of OPLWHA. Also, the correlation between networks and self-reported health was examined. Findings show that the OPLWHA had personal social networks that included three types of people: immediate kin, extended kin, and non-kin. Additionally, these networks varied by size. While the mean number of people in the smaller network (people from whom the OPLWHA can borrow an important sum of money) was less than one person (0.55), the mean number of people in the larger network was three (people with whom the OPLWHA enjoy socializing). Furthermore, only the network of people with whom OPLWHA enjoy socializing had a significant positive correlation on the self-rated health of OPLWHA. Consistent with prior research, we found that the mere existence of a network does not imply that the network has a positive correlation with the subject or that the network provides the social support needed to positively influence health. A study of the correlation between social network characteristics and health in the population of older people with HIV/AIDS is important as the number of OPLWHA continues to grow.

Abstract
HIV treatment initiatives have focused on increasing access to antiretroviral therapy (ART). There is growing evidence, however, that treatment availability alone is insufficient to stop the epidemic. In South Africa, only one third of individuals living with HIV are actually on treatment. Treatment refusal has been identified as a phenomenon among people who are asymptomatic, however, factors driving refusal remain poorly understood. We interviewed 50 purposively sampled participants who presented for voluntary counseling and testing in Soweto to elicit a broad range of detailed perspectives on ART refusal. We then integrated our core findings into an explanatory framework. Participants described feeling "too healthy" to start treatment, despite often having a diagnosis of AIDS. This subjective view of wellness was framed within the context of treatment being reserved for the sick. Taking ART could also lead to unintended disclosure and social isolation. These data provide a novel explanatory model of treatment refusal, recognizing perceived risks and social costs incurred when disclosing one's status through treatment initiation. Our findings suggest that improving engagement in care for people living with HIV in South Africa will require optimizing social integration and connectivity for those who test positive.

Abstract
In low- and middle-income countries (LMICs), naturally occurring social networks may be particularly vital to health outcomes as extended webs of social ties often are the principal source of various resources. Understanding how social network structure, and influential individuals within the network, may amplify the effects of interventions in LMICs, by creating, for example, cascade effects to non-targeted participants, presents an opportunity to improve the efficiency and effectiveness of public health interventions in such settings. We conducted a systematic review of PubMed, Econlit, Sociological Abstracts, and PsycINFO to identify a sample of 17 sociocentric network papers (arising from 10 studies) that specifically examined health issues in LMICs. We also separately selected to review 19 sociocentric network papers (arising from 10 other studies) on development topics related to wellbeing in LMICs. First, to provide a methodological resource, we discuss the sociocentric network study designs employed in the selected papers, and then provide a catalog of 105 name generator questions used to measure social ties across all the LMIC network papers (including both ego- and sociocentric network papers) cited in this review. Second, we show that network composition, individual network centrality, and network structure are associated with important health behaviors and health and development outcomes in different contexts across multiple levels of analysis and across distinct network types. Lastly, we highlight the opportunities for health researchers and practitioners in LMICs to 1) design effective studies and interventions in LMICs that account for the sociocentric network positions of certain individuals and overall network structure, 2) measure the spread of outcomes or intervention externalities, and 3) enhance the effectiveness and efficiency of aid based on knowledge of social structure. In summary, human health and wellbeing are connected through complex webs of dynamic social relationships. Harnessing such information may be especially important in contexts where resources are limited and people depend on their direct and indirect connections for support.

Abstract
In personal network studies, respondents (egos) are asked to report information about members of their personal network (alters); egos respond based on their perceptions. Previous studies of informant accuracy present a varied picture: Some find egos' reporting on their relationships with alters to be accurate; others do not. In our study of people living with HIV/AIDS (PLHA) in Uganda, egos were asked to invite up to four alters named during their interview to answer questions about their relationship with ego. Using Gower's general coefficient of similarity, we calculated a measure of accuracy both by variable and by alter. Our analysis by variable tends to confirm informant accuracy research, while our analysis by alter adds to the literature by identifying how accurate a particular ego is when discussing an alter and what characteristics might be associated with accuracy or inaccuracy.

Abstract
HIV infection remains highly stigmatized throughout sub-Saharan Africa despite the increasing availability of treatment. HIV-related stigma is commonly described to be highly prevalent in East Africa, but none of these studies have employed validated scales for measurement. We used data from 456 people living with HIV/AIDS in rural Uganda to validate the six-item Internalized AIDS-Related Stigma Scale. The scale demonstrated acceptable internal consistency (Cronbach's alpha = 0.73) and time stability. Exploratory factor analysis indicated the presence of a single factor. Construct validity was supported by observations that the scale was correlated with related constructs such as depression and mental health-related quality of life. The scale was able to discriminate between groups of persons who were different in terms of treatment status and their experience of HIV-related self-blame. Taken together, these findings suggest that the Internalized AIDS-Related Stigma Scale may be a useful tool for socio-behavioral HIV research.

HIV Clients as Agents for Prevention: A Social Network Solution. AIDS Res Treat 2012; 2012:815823.

Abstract
HIV prevention efforts to date have not explored the potential for persons living with HIV to act as change agents for prevention behaviour in their social networks. Using egocentric social network analysis, this study examined the prevalence and social network correlates of prevention advocacy behaviours (discussing HIV in general; encouraging abstinence or condom use, HIV testing, and seeking HIV care) enacted by 39 HIV clients in Uganda. Participants engaged in each prevention advocacy behaviour with roughly 50–70% of the members in their network. The strongest determinant of engaging in prevention advocacy with more of one's network members was having a greater proportion of network members who knew one's HIV seropositive status, as this was associated with three of the four advocacy behaviours. These findings highlight the potential for PLHA to be key change agents for HIV prevention within their networks and the importance of HIV disclosure in facilitating prevention advocacy.

Abstract
To explore how people living with HIV (PLHIV) and in care encourage others to adopt HIV-protective behaviours, we conducted in-depth interviews with a purposive sample of 40 HIV clinic patients in Kampala, Uganda. Content analysis was used to examine the message content, trigger events, and outcomes of HIV-prevention advocacy events initiated by the HIV clients with members of their social networks. The content themes included encouraging specific behaviours, such as HIV testing and treatment, condom use and non-promiscuity, as well as more general cautionary messages about protecting oneself from HIV infection. Common triggers for bringing up HIV-prevention advocacy information in a discussion or conversation included: wanting to prevent the targeted person from 'falling into the same problems,' wanting to benefit oneself with regard to avoiding re-infection, out of concern that the target would engage in higher-risk behaviour, due to observed changes in the target's health, and to convey information after receiving treatment at the clinic. The participants mostly reported positive or neutral responses to these advocacy events; negative responses were rare. Interventions to empower PLHIV to be agents of change could represent a new frontier for HIV prevention.
