“…Of course, the pattern of our results needs to be replicated in other studies with other designs before such a general conclusion that IMB factors are less protective in high risk situations. Little research has been conducted so far on the interplay of multiple levels of influence (i.e., individual, situational, dyadic) on HIV risk behaviors, but such studies have recently been called for to advance the science of HIV 88 and would increase understanding of the interplay of situational and social-cognitive factors.…”

The HIV/AIDS epidemic is disproportionately impacting young African Americans. Efforts to understand and address risk factors for unprotected sex in this population are critical in improving prevention efforts. Situational risk factors, such as relationship type and substance use before sex, are in need of further study. This study explored how established cognitive predictors of risky sexual behavior moderated the association between situational factors and unprotected sex among low-income, African American adolescents. The largest main effect on the number of unprotected sex acts was classifying the relationship as serious (event rate ratio = 10.18); other significant main effects were alcohol use before sex, participant age, behavioral skills, and level of motivation. HIV information moderated the effect of partner age difference, motivation moderated the effects of partner age difference and drug use before sex, and behavioral skills moderated the effects of alcohol and drug use before sex. This novel, partnership-level approach provides insight into the complex interactions of situational and cognitive factors in sexual risk taking.

“…[8][9][10] As power dynamics within relationships influence HIV risk behavior, the member of the couple with the greatest power may more directly influence dyadic decisionmaking and thereby encourage either safe or risky behaviors. 11 Building on previous women-focused research in the US 12 and Zambia, 13 an evidence-based HIV prevention model for couples was developed and pilot tested in the Zambian context. 14 The subsequent study was designed to reduce sexual risk behavior among urban, Zambian HIV-seroconcordant positive and -serodiscordant couples and compared 'intervention modalities' to assess whether the HIV risk-reduction intervention would be more likely to increase condom acceptability and decrease risk behavior when delivered to couples in a gender-concordant group or individual format.…”

Heterosexual HIV transmission remains the leading cause of HIV incidence in adult men and women in sub-Saharan Africa. This study assessed whether an HIV risk-reduction intervention would be more likely to increase sexual barrier acceptability and decrease risk behavior when delivered to couples in gender concordant groups or in an individual format. This study also examined the mutual impact of couple members as a source of influence on acceptability, and assessed whether product acceptability, intimate partner violence (IPV), and/or partner communication predicted sexual barrier use. HIV seroconcordant and serodiscordant couples (n=216) were recruited in Lusaka, Zambia, and randomized to a four session gender-concordant intervention. Participants were assessed at baseline, 6, and 12 months. Willingness to use barriers (p=0.012), acceptability (p<0.001), and barrier use (p<0.001) increased over time in both conditions, and were influenced by gender preferences. IPV decreased (p=0.040) and positive communication increased (p<0.001) in both conditions. Individual and gender concordant group sessions achieved similar increases in sexual barrier use following the intervention. Results highlight the influence of partners as well as product acceptability as predictors of sexual barrier use among couples in sub-Saharan Africa. Future prevention studies should consider both product acceptability and partner influence to achieve optimal sexual risk behavior outcomes.

“…These findings imply that efforts to prevent HIV transmission must incorporate the impact of social networks. Social networks can, therefore, play a dual role in HIV transmission: they serve as both the routes of transmission for the virus and the routes of dissemination for information related to HIV prevention and treatment services (32, 33). …”

Social Network Strategies to Address HIV Prevention and Treatment Continuum of Care Among At-risk and HIV-infected Substance Users: A Systematic Scoping Review

et al. 2016

Social network analysis (SNA) and social network-based interventions (SNI) are important analytical tools harnessing peer and family influences critical for HIV prevention and treatment among substance users. While SNA is an effective way to measure social network influences, SNI directly or indirectly involves network members in interventions. Even though these methods have been applied in heterogeneous ways, leading to extensive evidence-based practices, systematic reviews are however, lacking. We searched five bibliographic databases and identified 58 studies involving HIV in substance users that had utilized SNA or SNI as part of their methodology. SNA was used to measure network variables as inputs in statistical/mathematical models in 64% of studies and only 22% of studies used SNI. Most studies focused on HIV prevention and few addressed diagnosis (k=4), care linkage and retention (k=5), ART adherence (k=2), and viral suppression (k=1). This systematic review highlights both the advantages and disadvantages of social network approaches for HIV prevention and treatment and gaps in its use for HIV care continuum.
