Alcohol Expectancies and Inhibition Conflict as Moderators of the Alcohol-Unprotected Sex Relationship: Event-Level Findings from a Daily Diary Study Among Individuals Living with HIV in Cape Town, South Africa

Literature from sub-Saharan Africa and elsewhere supports a global association between alcohol and HIV risk. However, more rigorous studies using multiple event-level methods find mixed support for this association, suggesting the importance of examining potential moderators of this relationship. The present study explores the assumptions of alcohol expectancy theory and alcohol myopia theory as possible moderators that help elucidate the circumstances under which alcohol may affect individuals' ability to use a condom. Participants were 82 individuals (58 women, 24 men) living with HIV who completed daily phone interviews for 42 days which assessed daily sexual behavior and alcohol consumption. Logistic generalized estimating equation models were used to examine the potential moderating effects of inhibition conflict and sex-related alcohol outcome expectancies. The data provided some support for both theories and in some cases the moderation effects were stronger when both partners consumed alcohol.

Determinants of family planning service uptake and use of contraceptives among postpartum women in rural Uganda

OBJECTIVE

Uganda has one of the highest unmet needs for family planning globally, which is associated with negative health outcomes for women and population-level public health implications. The present cross-sectional study identified factors influencing family planning service uptake and contraceptive use among postpartum women in rural Uganda.

METHODS

Participants were 258 women who attended antenatal care at a rural Ugandan hospital. We used logistic regression models in SPSS to identify determinants of family planning service uptake and contraceptive use postpartum.

RESULTS

Statistically significant predictors of uptake of family planning services included: education (AOR = 3.03, 95 % CI 1.57-5.83), prior use of contraceptives (AOR = 7.15, 95 % CI 1.58-32.37), partner communication about contraceptives (AOR = 1.80, 95 % CI 1.36-2.37), and perceived need of contraceptives (AOR = 2.57, 95 % CI 1.09-6.08). Statistically significant predictors of contraceptive use since delivery included: education (AOR = 2.04, 95 % CI 1.05-3.95), prior use of contraceptives (AOR = 10.79, 95 % CI 1.40-83.06), and partner communication about contraceptives (AOR = 1.81, 95 % CI 1.34-2.44).

CONCLUSIONS

Education, partner communication, and perceived need of family planning are key determinants of postpartum family planning service uptake and contraceptive use, and should be considered in antenatal and postnatal family planning counseling.

Barriers to and acceptability of provider-initiated HIV testing and counselling and adopting HIV-prevention behaviours in rural Uganda: a qualitative study

In Uganda, a nationwide scale-up of provider-initiated HIV testing and counselling presents an opportunity to deliver HIV-prevention services to large numbers of people. In a rural Ugandan hospital, focus group discussions and key informant interviews were conducted with outpatients receiving provider-initiated HIV testing and counselling and staff to explore the HIV-prevention information, motivation and behavioural skills strengths and weaknesses, and community-level and structural barriers to provider-initiated HIV testing and counselling acceptability and HIV prevention among this population. Strengths and weakness occurred at all levels, and results suggest brief client-centred interventions during provider-initiated HIV testing and counselling may be an effective approach to increase prevention behaviours in outpatient settings.

HIV transmission risk behavior among HIV-positive patients receiving antiretroviral therapy in KwaZulu-Natal, South Africa

The aim of this investigation was to identify factors associated with HIV transmission risk behavior among HIV-positive women and men receiving antiretroviral therapy (ART) in KwaZulu-Natal, South Africa. Across 16 clinics, 1,890 HIV+ patients on ART completed a risk-focused audio computer-assisted self-interview upon enrolling in a prevention-with-positives intervention trial. Results demonstrated that 62 % of HIV-positive patients' recent unprotected sexual acts involved HIV-negative or HIV status unknown partners. For HIV-positive women, multivariable correlates of unprotected sex with HIV-negative or HIV status unknown partners were indicative of poor HIV prevention-related information and of sexual partnership-associated behavioral skills barriers. For HIV-positive men, multivariable correlates represented motivational barriers, characterized by negative condom attitudes and the experience of depressive symptomatology, as well as possible underlying information deficits. Findings suggest that interventions addressing gender-specific and culturally-relevant information, motivation, and behavioral skills barriers could help reduce HIV transmission risk behavior among HIV-positive South Africans.

An empirical test of the Theory of Planned Behaviour applied to contraceptive use in rural Uganda

There is a high unmet need for contraceptives in developing countries such as Uganda, with high population growth, where efforts are needed to promote family planning and contraceptive use. Despite this high need, little research has investigated applications of health-behaviour-change theories to contraceptive use among this population. This study tested the Theory of Planned Behaviour's ability to predict contraceptive-use-related behaviours among post-partum women in rural Uganda. Results gave modest support to the theory's application and suggest an urgent need for improved theory-based interventions to promote contraceptive use in the populations of developing countries.

Event-level association between alcohol use and unprotected sex during last sex: evidence from population-based surveys in sub-Saharan Africa

BACKGROUND

HIV and risky alcohol use are intertwined public health issues in sub-Saharan Africa. Research supports the association between alcohol and unprotected sex, but there is limited data using event-level analysis to examine this relationship.

METHODS

Using data from Demographic Health Surveys and AIDS Information Surveys collected in 8 sub-Saharan African countries (Kenya, Lesotho, Mozambique, Rwanda, Swaziland, Tanzania, Zambia, and Zimbabwe) drunkenness (reporting male partner or both male and female partner being drunk during last sexual intercourse) at last sex was tested as a predictor of unprotected last sex among the male (n = 24,512) and female (n = 28,229) participants. Partner type, HIV test results, and the other variables were evaluated as effect modifiers of this relationship.

RESULTS

Drunkenness at last sex had a negative effect on the likelihood of condom use among men (AOR 0.84, 95% CI 0.72-0.99) and a marginally significant effect among women (AOR 0.87, 95% CI 0.59-1.02) in Southern Africa. However, for men in Southern Africa, this effect was primarily observed with steady partners. Contrary to predictions, in both Southern and Eastern Africa, for men, drunkenness during sex with casual partners increased the odds of condom use.

CONCLUSIONS

These data indicate a need to implement HIV prevention efforts that consider the role of alcohol use in precipitating unprotected sex and how it varies based upon partner type.

Understanding HIV transmission risk behavior among HIV-infected South Africans receiving antiretroviral therapy: an information--motivation--behavioral skills model analysis

OBJECTIVE

The current study applied the Information-Motivation-Behavioral Skills (IMB) model (Fisher & Fisher, 1992; Fisher & Fisher, 1993) to identify factors associated with human immunodeficiency virus (HIV) transmission risk behavior among HIV-infected South Africans receiving antiretroviral therapy (ART), a population of considerable significance for curtailing, or maintaining, South Africa's generalized HIV epidemic.

METHODS

HIV prevention information, HIV prevention motivation, HIV prevention behavioral skills, and HIV transmission risk behavior were assessed in a sample of 1,388 South Africans infected with HIV and receiving ART in 16 clinics in KwaZulu-Natal, South Africa.

RESULTS

Findings confirmed the assumptions of the IMB model and demonstrated that HIV prevention information and HIV prevention motivation work through HIV prevention behavioral skills to affect HIV transmission risk behavior in this population. Subanalyses confirmed these relationships for HIV transmission risk behavior overall and for HIV transmission risk behavior with partners perceived to be HIV-negative or HIV-status unknown. A consistent pattern of gender differences showed that for men, HIV prevention information and HIV prevention motivation may have direct links with HIV preventive behavior, whereas for women, the effect of HIV prevention motivation works through HIV prevention behavioral skills to affect HIV preventive behavior.

CONCLUSION

These IMB model-based findings suggest directions for HIV prevention interventions with South African men and women living with HIV and on ART as an important component of overall strategies to contain South Africa's generalized HIV epidemic.

Alcohol-involved sexual risk behavior among heavy drinkers living with HIV/AIDS: negative affect, self-efficacy, and sexual craving

Evidence of the effects of negative affect (NA) and sexual craving on unprotected sexual activity remains scant. We hypothesized that NA and sexual craving modify the same day association between low self-efficacy to use condoms and unprotected anal or vaginal sex, and the same-day association between alcohol use during the 3 hours prior to sexual activity and unprotected sex. We used an electronic daily diary, drawing on a sample of 125 men and women recruited from an agency serving economically disadvantaged persons living with HIV/AIDS. Casual or steady partner type designation and perceived partner HIV serostatus were also examined. Findings support the hypothesized moderating effects of high NA and sexual craving on the association between low self-efficacy and unprotected sex, and the association between alcohol use and unprotected sex. Implications are discussed.

Home-based HIV voluntary counselling and testing (VCT) for improving uptake of HIV testing

BACKGROUND

The low uptake of HIV voluntary counselling and testing (VCT) has hindered global attempts to prevent new HIV infections and has limited scale-up of HIV care and treatment. Globally, only 10% of HIV-infected individuals are aware of their HIV status. One approach to increase uptake is home-based HIV VCT, which may be effective in increasing the number of patients on treatment and preventing new infections.

OBJECTIVES

To establish the effect of home-based HIV VCT on uptake of HIV testing

SEARCH STRATEGY

We searched MEDLINE (February 2007), EMBASE (February 2007), CENTRAL (February 2007), AIDSearch (February 2007), LILACS, CINAHL and Sociofile. We also contacted relevant researchers. The original review search strategy was updated in 2008.

SELECTION CRITERIA

Randomised controlled trials comparing home-based HIV VCT with other testing models

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, assessed methodological quality, and extracted data. We planned to conduct statistical analysis using the Review Manager software and calculate summary statistics (relative risks (RRs) with 95% confidence intervals (CI)) for primary outcomes.

MAIN RESULTS

Only one study from developing countries met the inclusion criteria and was included in the review. The study, a cluster randomised trial (10 clusters, n=849) compared VCT uptake between an optional location (including home-based) and a local clinic location in a population-based HIV survey. The study showed a higher uptake of VCT among participants in the optional-location group. Uptake was significantly greater in the optional-location group in those who were pre-test counselled only (RR=4.6; 95% CI 3.58 to 5.91); pretest counselled and tested (RR=4.6; 95% CI 3.51 to 5.92); and post-test counselled and received the test result (RR=4.8; 95% CI 3.62 to 6.21). This study, however, had significant methodological problems limiting further analysis and interpretation.

AUTHORS' CONCLUSIONS

Although home-based HIV VCT has the potential to enhance VCT uptake in developing countries, insufficient data exist to recommend large-scale implementation of home-based HIV testing. Further studies are needed to determine if home-based VCT is better than facility-based VCT in improving VCT uptake.

Craving and self-efficacy in the first five weeks of methadone maintenance therapy: a daily process study

OBJECTIVE

Among individuals initiating methadone maintenance therapy for heroin addiction, low craving and high self-efficacy are thought to predict treatment response; however, in the case of craving, findings have been inconsistent. This study will test two hypotheses: (1) craving and self-efficacy both predict treatment response and (2) withdrawal symptoms and sleep quality predict greater craving and greater self-efficacy, respectively.

METHOD

An exploratory study using electronic diary data and multilevel models examined these hypotheses. A sample of 21 heroin users was recruited during the first 1-2 days of methadone maintenance therapy to take part in a 5-week diary study. Comparisons were made between days before participants reached a 70 mg or greater dose and subsequent days. This is in keeping with research showing that this dosage corresponds to optimal opioid receptor blockade.

RESULTS

Analysis of 449 diary records nested within 21 participants showed a marked decline in heroin use on days subsequent to the 70 mg methadone dosage plateau. Controlling for methadone dosage plateau, the likelihood of heroin use was lower on days in which participants reported both high self-efficacy and low craving, as compared with other days. Support was found for hypothesized direct associations between craving and withdrawal symptoms and between self-efficacy and sleep quality.

CONCLUSIONS

Consistent with a previously published theory, the effect of low craving on positive response to methadone maintenance therapy is evident on days distinguished by high self-efficacy. Also, improving patients' sleep quality may enhance the benefits of methadone maintenance therapy.

WITHDRAWN: Home-based HIV voluntary counseling and testing in developing countries

BACKGROUND

The low uptake of HIV voluntary counseling and testing (VCT), an effective HIV prevention intervention, has hindered global attempts to prevent new HIV infections, as well as limiting the scale-up of HIV care and treatment for the estimated 38 million infected persons. According to UNAIDS, only 10% of HIV-infected individuals worldwide are aware of their HIV status. At this point in the HIV epidemic, a renewed focus has shifted to prevention, and with it, a focus on methods to increase the uptake of HIV VCT. This review discusses home-based HIV VCT delivery models, which, given the low uptake of facility-based testing models, may be an effective avenue to get more patients on treatment and prevent new infections.

OBJECTIVES

(1) To identify and critically appraise studies addressing the implementation of home-based HIV voluntary counseling and testing in developing countries. (2) To determine whether home-based HIV voluntary counseling and testing (HBVCT) is associated with improvement in HIV testing outcomes compared to facility-based models.

SEARCH STRATEGY

We searched online for published and unpublished studies in MEDLINE (February 2007), EMBASE (February 2007), CENTRAL (February 2007). We also searched databases listing conference proceedings and abstracts; AIDSearch (February 2007), The Cochrane Library (Issue 2, 2007), LILACS, CINAHL and Sociofile. We also contacted authors who have published on the subject of review.

SELECTION CRITERIA

We searched for randomized controlled trials (RCTs) and non-randomized trials (e.g., cohort, pre/post-intervention and other observational studies) comparing home-based HIV VCT against other testing models.

DATA COLLECTION AND ANALYSIS

We independently selected studies, assessed study quality and extracted data. We expressed findings as odds ratios (OR), and relative Risk (RR) together with their 95% confidence intervals (CI).

MAIN RESULTS

We identified one cluster-randomized trial and one pre/post-intervention (cohort) study, which were included in the review. An additional two ongoing RCTs were identified. All identified studies were conducted in developing countries. The two included studies comprised one cluster-randomized trial conducted in an urban area in Lusaka, Zambia and one pre/post-intervention (cohort) study, part of a rural community cohort in Southwestern Uganda. The two studies, while differing in methodology, found very high acceptability and uptake of VCT when testing and or results were offered at home, compared to the standard (facility-based testing and results). In the cluster-randomized trial (n=849), subjects randomized to an optional testing location (including home-based testing) were 4.6 times more likely to accept VCT than those in the facility arm (RR 4.6, 95% CI 3.6-6.2). Similarly, in the pre/post study (n=1868) offering participants the option of home delivery of results increased VCT uptake. In the intervention year (home delivery) participants were 5.23 times more likely to receive their results than during the year when results were available only at the facility. (OR 5.23 95% CI 4.02-6.8).

AUTHORS' CONCLUSIONS

Home-based testing and/or delivery of HIV test results at home, rather than in clinics, appears to lead to higher uptake in testing. However, given the limited extant literature and the limitations in the included existing studies, there is not sufficient evidence to recommend large-scale implementation of the home-based testing model.

Initial outcomes of provider-initiated routine HIV testing and counseling during outpatient care at a rural Ugandan hospital: risky sexual behavior, partner HIV testing, disclosure, and HIV care seeking

Provider-initiated routine HIV testing is being scaled up throughout the world, however, little is known about the outcomes of routine HIV testing on subsequent behavior. This study examined the initial outcomes of provider-initiated routine HIV testing at a rural Ugandan hospital regarding partner HIV testing, sexual risk behavior, disclosure, and HIV care seeking. In a prospective cohort study, 245 outpatients receiving routine HIV testing completed baseline and 3-month follow-up interviews. After receiving routine HIV testing the percentage of participants engaging in risky sex decreased from 70.1% to 50.3% among HIV-negative and from 75.0% to 53.5% among HIV-positive participants, the percentage knowing their partner(s)' HIV status increased from 18.7% to 34.3% of HIV-negative and from 14.3% to 35.7% of HIV-positive participants. Among those reporting risky sex at baseline, HIV-positive participants were more likely to eliminate risky sex in general and specifically to become abstinent at follow-up than were HIV-negative participants. Similarly, unmarried participants who were risky at baseline were more likely to become safe in general, become abstinent, and start 100% condom use than were married/cohabitating participants. Rates of disclosure were high. Over 85% of those who tested HIV positive enrolled in care. Routine HIV testing in this setting may promote earlier HIV diagnosis and access to care but leads to only modest reductions in risky sexual behavior. To fully realize the potential HIV prevention benefits of routine HIV testing an emphasis on tailored risk-reduction counseling may be necessary.

Provider-initiated HIV testing in health care settings: should it include client-centered counselling?

To increase access to HIV testing, the WHO and CDC have recommended implementing provider-initiated HIV testing (PITC). To address the resource limitations of the PITC setting, WHO and CDC suggest that patient-provider interactions during PITC may need to focus on providing information and referrals, instead of engaging patients in client-centered counselling, as is recommended during client-initiated HIV testing. Providing HIV prevention information has been shown to be less effective than client-centered counselling in reducing HIV-risk behaviour and STI incidence. Therefore, concerns exist about the efficacy of PITC as an HIV prevention approach. However, reductions in HIV incidence may be greater if more people know their HIV status through expanded availability of PITC, even if PITC is a less effective prevention intervention than is client-initiated HIV testing for individual patients. In the absence of an answer to this public health question, adaptation of effective brief client-centered counselling approaches to PITC should be explored along with research assessing the efficacy of PITC.

Three brief alcohol screens for detecting hazardous drinking in incarcerated women

OBJECTIVE

Screening methods for hazardous drinking have not been evaluated in a population of incarcerated women. This study examines abbreviated versions of the Alcohol Use Disorders Identification Test (AUDIT) and the National Institute on Alcohol Abuse and Alcoholism (NIAAA) heavy episodic drinking criterion in a sample of female detainees.

METHOD

A total of 2,079 women at the Adult Correctional Institute in Rhode Island were approached for screening between February 2004 and June 2007. The AUDIT-consumption (AUDIT-C), AUDIT-3, and the NIAAA heavy episodic drinking criterion (four or more drinks on one occasion for women) were compared with the full AUDIT at different cut points.

RESULTS

More than 55% of the sample endorsed an AUDIT score of 4 or greater--the NIAAA recommended threshold for detecting hazardous drinking. The three-item AUDIT-C with a cut score of 3 yielded a classification most consistent with the AUDIT score of 4 or more; sensitivity and specificity exceeded .9, and 91.5% of participants were correctly classified. The AUDIT-3 and NIAAA episodic drinking criteria were less sensitive measures. We found no evidence of interactions between the screening instruments and age or ethnicity.

CONCLUSIONS

The three-item AUDIT-C has robust test characteristics for detecting hazardous drinking in female inmates. Universal screening for hazardous drinking is recommended for incarcerated women, given their high rates of alcohol misuse.

Alcohol, helping young adults to have unprotected sex with casual partners: findings from a daily diary study of alcohol use and sexual behavior

PURPOSE

To examine the event-level association between alcohol consumption and the likelihood of unprotected sex among college-age young adults considering contextual factors of partner type and amount of alcohol consumed.

METHODS

A 30-day, Web-based, structured daily diary was used to collect daily reports of sexual behaviors and alcohol use from 116 sexually active young adults, yielding 2,764 diary records. Each day we assessed the prior evening's behavior regarding alcohol consumption, opportunities for sex, sexual intercourse, condom use, and contextual factors including type of sexual partner.

RESULTS

Based on multilevel models, drinking proximal to events of sexual intercourse increased the likelihood of unprotected sex with casual but not steady partners. For women there was a positive association between number of drinks and a greater likelihood of unprotected sex with casual partners but a negative association with steady partners. Drinking during situations involving opportunities for sex with casual partners increased the likelihood of sex. For women especially, drinking more increased the likelihood of sex occurring regardless of partner type.

CONCLUSIONS

Failure to assess the contextual determinants of the alcohol-unprotected sex association may result in underestimates of the magnitude of this association. These data highlight an important area for intervention with young adults: reducing alcohol-involved sexual risk behavior with casual partners, especially among women.

Today I'll use a condom, but who knows about tomorrow: a daily process study of variability in predictors of condom use

OBJECTIVE

Most models of health behavior change applied to condom use behavior have focused on individual differences in theoretical constructs to explain condom use or nonuse, while ignoring the possibility that day-to-day within-person changes in these constructs may contribute to understanding behavior. The goal of the present study was to investigate day-to-day variability in condom use attitudes, self-efficacy, and behavioral intentions and assess the utility of this variability in predicting the likelihood of condom use each day.

DESIGN

A 30-day Web-based structured daily diary was used to collect daily reports of sexual behaviors and data on theoretical predictors of condom use behavior from sexually active college students (N = 116).

MAIN OUTCOME MEASURES

The authors investigated whether condom use attitudes, self-efficacy, and behavioral intentions vary day to day; whether this within-person variability predicts condom use behavior; and whether negative affective states explain this variability.

RESULTS AND CONCLUSIONS

Within-person variability was found for each of the constructs. Within-person day-to-day changes in behavioral intentions and attitudes predicted the instances in which an individual used a condom and daily negative affect partially explained within-person day-to-day changes in behavioral intentions and self-efficacy. Implications for models of health behavior change and for behavior change interventions are discussed.

A daily process investigation of alcohol-involved sexual risk behavior among economically disadvantaged problem drinkers living with HIV/AIDS

Alcohol use is believed to increase sexual risk behavior among people living with HIV/AIDS (PLWHA). As drinking and sexual risk acts often occur in the same social contexts, this association is difficult to confirm. In this study, electronic daily diaries were completed by 116 PLWHA over 5 weeks. This yielded a total of 1,464 records consisting of data pertaining to discrete occasions of anal and vaginal sex. Simultaneous within- and between-person multilevel analyses were conducted, including situational variables (partner type, partner serostatus, partner drinking) and individual difference variables (gender, level of alcohol dependence). The resulting model explains 27.5% of the variance and reveals that interactions among these situational and individual difference variables predict changes in the estimated rate of unprotected sex (US). Also, in defined contexts, the amount of alcohol consumed prior to sex significantly affects the rate of US among members of the sample. Implications are discussed.

The idiographic study of inconsistent condom use behavior of persons living with HIV

A pilot study was conducted to assess the feasibility of using, in a multiply disadvantaged population, an electronic daily diary to test hypotheses linking affective states to variability in psychosocial determinants of condom use. Twenty-one mostly non-Caucasian individuals reporting profound economic disadvantage, heavy alcohol use and HIV infection completed a 5-7 minute interactive voice response (IVR) telephone-based survey daily for three weeks. Potentially affect-related within-person variability was observed in HIV-preventive attitudes, intentions and self-efficacy. Surprisingly, in this sample, HIV-preventive attitudes, intentions and self-efficacy exhibited as much, or greater, variability within persons as compared to between persons. Positive affect was found to significantly co-vary with self-efficacy to practice safer sex B=0.20, t((199))=2.14, p=0.03. For each unit increase in daily positive affect, daily self-efficacy increased by 0.20. Results suggest that a daily diary methodology is both feasible in a high-risk population and may offer new insights into understanding unprotected sexual behavior.

A brief individualized computer-delivered sexual risk reduction intervention increases HIV/AIDS preventive behavior

PURPOSE

One objective of translational science is to identify elements of human immunodeficiency virus (HIV) risk-reduction interventions that have been shown to be effective and find new ways of delivering these interventions to the community to ensure that they reach the widest possible audience of at-risk individuals. The current study reports the development and evaluation of a computer-delivered, theory-based, individually tailored HIV risk-reduction intervention.

METHODS

This study evaluated the effectiveness of a custom computerized HIV/AIDS risk reduction intervention at increasing HIV/AIDS preventive behaviors in a randomized trial with 157 college students. The intervention content and delivery were based on the Information-Motivation-Behavioral Skills Model of Health Behavior Change and used Motivational Interviewing techniques. Participants completed a baseline assessment of HIV prevention information, motivation, behavioral skills and behavior, attended two brief computer-delivered intervention sessions, and completed a follow-up assessment.

RESULTS

As compared to the control group (a nutrition education tutorial), participants who interacted with the computer-delivered HIV/AIDS risk reduction intervention exhibited a significant increase in risk reduction behavior. Specifically, participants reported a greater frequency of keeping condoms available and displayed greater condom-related knowledge at a four-week follow-up session; among sexually active participants, there was a significant increase in self-reported condom use.

CONCLUSIONS

Delivery of brief individually tailored HIV/AIDS risk reduction interventions via computer may be an effective HIV/AIDS prevention approach for adolescents. More research is needed to further support the effectiveness of this type of intervention and determine the generalizability of these findings to economically and educationally disadvantaged adolescents.

Sexual risk behaviour among HIV-positive individuals in clinical care in urban KwaZulu-Natal, South Africa

We assessed the incidence and predictors of unprotected sex among 152 HIV-positive patients in clinical care in KwaZulu-Natal, South Africa. Nearly 50% were sexually active; 30% of those reported unprotected sex. Alcohol use during sex, reporting forced sex, sex with a perceived HIV-positive partner, and sex with a casual partner predicted more unprotected sex, whereas HIV status disclosure was related to less unprotected sex. These findings highlight the need for linking HIV prevention and care in Africa.

Why are you bringing up condoms now? The effect of message content on framing effects of condom use messages

According to prospect theory (A. Tversky & D. Kahneman, 1981), messages advocating a low-risk (i.e., easy, low-cost) behavior are most effective if they stress the benefits of adherence (gain framed), whereas messages advocating a risky behavior are most effective if they stress the costs of nonadherence (loss framed). Although condom use is viewed as a low-risk behavior, it may entail risky interpersonal negotiations. Study 1 (N = 167) compared ratings of condom use messages advocating relational behaviors (e.g., discussing condoms) or health behaviors (e.g., carrying condoms). As predicted, loss-framed relational messages and gain-framed health messages received higher evaluations. Study 2 (N = 225) offers a replication and evidence of issue involvement and gender as moderators. Results are discussed with reference to the design of condom use messages.
