Development of a Brief Scale to Measure AIDS-Related Stigma in South Africa

Although there has been progress in AIDS stigma research, there are no multi-item AIDS stigma scales that have been shown reliable and valid in Africa. The current research reports the development of the nine-item AIDS-Related Stigma Scale. Research conducted in five South African communities (N = 2306) found the scale internally consistent, α = 0.75 and time stable over 3 months, r = 0.67. The scale was also reliable in three different languages (English, Xhosa, and Afrikaans). Correlations showed that the AIDS-Related Stigma Scale was moderately inversely correlated with years of education and AIDS knowledge. In addition, individuals who stated that HIV positive persons should conceal their HIV status had higher AIDS-Related Stigma Scale scores. Also supporting the scale’s construct validity, individuals who refused to report whether they had been tested for HIV scored higher on the AIDS-Related Stigma Scale.

Health-related Internet use, coping, social support, and health indicators in people living with HIV/AIDS: Preliminary results from a community survey

Widespread Internet use has revolutionized health information and patient education for persons with chronic illnesses. The authors surveyed 147 HIV-positive persons to examine factors associated with Internet use and associations between Internet use and health. Information, motivation, and behavioral skills associated with using the Internet were related to Internet use. The authors found that health-related Internet use was associated with HIV disease knowledge, active coping, information seeking coping, and social support among persons who were using the Internet. These preliminary findings suggest an association between using the Internet for health-related information and health benefits among people living with HIV/AIDS, supporting the development of interventions to close the digital divide in HIV/AIDS care.

Gender attitudes, sexual violence, and HIV/AIDS risks among men and women in Cape Town, South Africa

This study examined gender attitudes and sexual violence‐supportive beliefs (rape myths) in a sample of South African men and women at risk for HIV transmission. Over 40% of women and 16% of men had been sexually assaulted, and more than one in five men openly admitted to having perpetrated sexual assault. Traditional attitudes toward womens social and gender roles, as well as rape myths, were endorsed by a significant minority of both men and women. Multivariate analyses showed that for men, sexual assault history and rape myth acceptance, along with alcohol and other drug use history, were significantly related to cumulative risks for HIV infection. In contrast, although we found that women were at substantial risk for sexually transmitted infection (STI), including HIV, womens risks were only related to lower levels of education and alcohol use history. We speculate that womens risks for STI/HIV are the product of partner characteristics and male‐dominated relationships, suggesting the critical importance of intervening with men to reduce womens risks for sexual assault and STI/HIV.

Integrated gender-based violence and HIV risk reduction intervention for South African men: results of a quasi-experimental field trial.

South Africa is in the midst of one of the world’s most devastating HIV/AIDS epidemics and there is a well-documented association between violence against women and HIV transmission. Interventions that target men and integrate HIV prevention with gender-based violence prevention may demonstrate synergistic effects. A quasi-experimental field intervention trial was conducted with two communities randomly assigned to receive either: (a) a five session integrated intervention designed to simultaneously reduce gender-based violence (GBV) and HIV risk behaviors (N = 242) or (b) a single 3-hour alcohol and HIV risk reduction session (N = 233). Men were followed for 1-, 3-, and 6-months post intervention with 90% retention. Results indicated that the GBV/HIV intervention reduced negative attitudes toward women in the short term and reduced violence against women in the longer term. Men in the GBV/HIV intervention also increased their talking with sex partners about condoms and were more likely to have been tested for HIV at the follow-ups. There were few differences between conditions on any HIV transmission risk reduction behavioral outcomes. Further research is needed to examine the potential synergistic effects of alcohol use, gender violence, and HIV prevention interventions.

Association Between Health Literacy and HIV Treatment Adherence: Further Evidence from Objectively Measured Medication Adherence

Background. People with lower-health literacy are vulnerable to health problems. Studies that have examined the association between literacy and medication adherence have relied on self-reported adherence, which is subject to memory errors, perhaps even more so in people with poor literacy. Purpose. To examine the association between health literacy and objectively assessed HIV treatment adherence. Methods. Men and women (N = 145) receiving antiretroviral therapy completed a test of health literacy and measures of common adherence markers. Medication adherence was monitored by unannounced pill counts. Results. Median adherence was 71%; participants with lower-health literacy also demonstrated poorer adherence compared to participants with higher literacy. Hierarchical regression showed literacy predicted adherence over and above all other factors. Sensitivity tests showed the same results for 80% and 90% adherence. Conclusions. The association between literacy and adherence appears robust and was confirmed using an objective measure of medication adherence.

Adherence to antiretroviral therapy assessed by unannounced pill counts conducted by telephone.

BACKGROUNDUnannounced pill counts conducted in patients’ homes is a valid objective method for monitoring medication adherence that is unfortunately costly and often impractical. Conducting unannounced pill counts by telephone may be a viable alternative for objectively assessing medication adherence.PURPOSETo test an unannounced pill count assessment of adherence conducted by telephone.METHODSHIV-positive men and women (N = 77) in Atlanta GA completed an unannounced telephone-based pill count immediately followed by a pill count conducted in an unannounced home visit.RESULTSA high degree of concordance was observed between phone and home-based number of pills counted (Intraclass correlation, ICC = .997, 95% CI .995–.998, P < .001) and percent of pills taken (ICC = .990, 95% CI .986–.992, P < .001). Concordance between adherence above/below 90% and phone/home counts was 95%, Kappa coefficient = .995. Concordance between pill counts was not influenced by participant education or health literacy and was maintained when the data were censored to remove higher levels of adherence. Analyses of discordant pill counts found the most common source of error resulted from overcounted doses in pillboxes on the telephone.CONCLUSIONSUnannounced phone-based pill counts offer an economically and logistically feasible objective method for monitoring medication adherence.

Health and Treatment Implications of Food Insufficiency among People Living with HIV/AIDS, Atlanta, Georgia

HIV/AIDS is concentrated among the inner-city poor and poverty may directly interfere with HIV treatment. This study examined food insufficiency in relation to HIV-related health and treatment. A sample of 344 men and women living with HIV/AIDS in Atlanta, Georgia completed measures of food security, health, and HIV disease progression and treatment. HIV treatment adherence was monitored using unannounced pill counts. Results showed that half of people living with HIV/AIDS in this study lacked sufficient food, and food insufficiency was associated with multiple indicators of poor health, including higher HIV viral loads, lower CD4 cell counts, and poorer treatment adherence. Adjusted analyses showed that food insufficiency predicted HIV treatment non-adherence over and above years of education, employment status, income, housing, depression, social support, and non-alcohol substance use. Hunger and food insecurity are prevalent among people living with HIV/AIDS, and food insufficiency is closely related to multiple HIV-related health indicators, particularly medication adherence. Interventions that provide consistent and sustained meals to people living with HIV/AIDS are urgently needed.

The Role of Stigma and Medical Mistrust in the Routine Health Care Engagement of Black Men Who Have Sex With Men

UNLABELLED Objectives: We assessed how health care-related stigma, global medical mistrust, and personal trust in ones health care provider relate to engaging in medical care among Black men who have sex with men (MSM). METHODS In 2012, we surveyed 544 Black MSM attending a community event. We completed generalized linear modeling and mediation analyses in 2013. RESULTS Twenty-nine percent of participants reported experiencing racial and sexual orientation stigma from heath care providers and 48% reported mistrust of medical establishments. We found that, among HIV-negative Black MSM, those who experienced greater stigma and global medical mistrust had longer gaps in time since their last medical exam. Furthermore, global medical mistrust mediated the relationship between stigma and engagement in care. Among HIV-positive Black MSM, experiencing stigma from health care providers was associated with longer gaps in time since last HIV care appointment. CONCLUSIONS Interventions focusing on health care settings that support the development of greater awareness of stigma and mistrust are urgently needed. Failure to address psychosocial deterrents will stymie progress in biomedical prevention and cripple the ability to implement effective prevention and treatment strategies.

A simple single-item rating scale to measure medication adherence: further evidence for convergent validity.

Background: Self-report measures of medication adherence are inexpensive and minimally intrusive. However, the validity of self-reported adherence is compromised by recall errors for missed doses and socially desirable responding. Method: Examined the convergent validity of 2 self-report adherence measures administered by computerized interview: (a) recall of missed doses and (b) a single-item visual analogue rating scale (VAS). Adherence was also monitored using unannounced phone-based pill counts that served as an objective benchmark. Results: The VAS obtained adherence estimates that paralleled unannounced pill counts (UPCs). In contrast, self-reported recall (SR-recall) of missed medications consistently overestimated adherence. Correlations with participant characteristics also suggested that the computer-administered VAS was less influenced by response biases than SR-recall of missed medication doses. Conclusions: A single-item VAS offers an inexpensive and valid method of assessing medication adherence that may be useful in clinical as well as research settings.

Monitoring Medication Adherence by Unannounced Pill Counts Conducted by Telephone: Reliability and Criterion-Related Validity

Abstract Background: Although demonstrated valid for monitoring medication adherence, unannounced pill counts conducted in patients’ homes are costly and logistically challenging. Telephone-based unannounced pill counts offer a promising adaptation that resolves most of the limitations of home-based pill counting. Purpose: We tested the reliability and criterion-related validity of a telephone-based unannounced pill count assessment of antiretroviral adherence. Method: HIV-positive men and women (N = 89) in Atlanta, Georgia, completed a telephone-based unannounced pill count and provided contemporaneous blood specimens to obtain viral loads; 68 participants also received an immediate second pill count conducted during an unannounced home visit. Results: A high degree of concordance was observed between the number of pills counted on the telephone and in the home (intraclass correlation [ICC] = .981, p < .001) and percent of pills taken (ICC = .987, p < .001). Adherence obtained by the telephone count and home count reached 92% agreement (Kappa coefficient = .94). Adherence determined by telephone-based pill counts also corresponded with patient viral load, providing evidence for criterion-related validity. Conclusion: Unannounced telephone-based pill counts offer a feasible objective method for monitoring medication adherence.
