On the new call for HIV prevention research.

Comments on the review by J. A. Kelly et al (see record 1994-10963-001) regarding HIV prevention programs. The need for psychologists to play a major role in HIV prevention research and in applied prevention programs is discussed. If the HIV epidemic is to be stemmed, psychologists must accept the challenge of defining treatments, confirming their efficacy, and promoting their implementation on a scale never before undertaken.

HIV risk reduction interventions for persons with severe mental illness

Recent seroprevalence studies have shown alarming rates of HIV infection among severely mentally ill men and women in large urban areas, and HIV behavioral epidemiology research indicates that a substantial proportion of seriously mentally ill adults engage in activities that increase their vulnerability to HIV/AIDS. In this paper, the research literature on HIV prevention interventions is reviewed including reports that have described HIV prevention programs, studies that have used uncontrolled pre- and postintervention methods to evaluate risk reduction interventions, and those that have used rigorous randomized designs and examined risk behavior change. Collectively, these studies show that intensive, small-group interventions that target a variety of risk-related dimensions-including knowledge, attitudes, and motivations, and behavioral and cognitive skills-can produce at least short-term reductions in high-risk sexual behavior among the severely mentally ill. A number of gaps in the research literature are identified including the need to: (a) better tailor interventions to risk situations encountered by the mentally ill; (b) develop gender-tailored interventions; (c) examine and implement HIV prevention programs so they help persons sustain behavior change; (d) explore one-on-one counseling and community-level intervention methods; and (e) develop risk reduction interventions for already-seropositive individuals. Implications for service provision are discussed.     

Cost-effectiveness of a community-level HIV risk reduction intervention

OBJECTIVES: The authors evaluated the cost-effectiveness of a community-level HIV prevention intervention that used peer leaders to endorse risk reduction among gay men. METHODS: A mathematical model of HIV transmission was used to translate reported changes in sexual behavior into an estimate of the number of HIV infections averted. RESULTS: The intervention cost $17,150, or about $65,000 per infection averted, and was therefore cost-saving, even under very conservative modeling assumptions. CONCLUSIONS: For this intervention, the cost of HIV prevention was more than offset by savings in averted future medical care costs. Community-level interventions to prevent HIV transmission that use existing social networks can be highly cost-effective.     

Psychological interventions to prevent HIV infection are urgently needed: New priorities for behavioral research in the second decade of AIDS.

Behavior change remains the only means for primary prevention of HIV disease. Psychology should take a leading role in efforts to curtail the epidemic, but has not contributed to HIV prevention at a level proportionate to the urgency of the crisis. The authors propose an updated agenda for behavioral research on AIDS-HIV prevention implementing accelerated community trials of promising behavior change models, conducting trials of community-level interventions on a large scale and focused on populations most vulnerable to HIV infections, establishing partnerships between HIV research and community service organizations, integrating efforts from across psychology disciplines to advance and refine HIV prevention interventions, and mobilizing interdisciplinary HIV prevention resources and communication mechanisms to rapidly translate research findings to community and public policy arenas.

Information-motivation-behavioral skills model-based HIV risk behavior change intervention for inner-city high school youth.

This study assessed the effects of 3 theoretically grounded, school-based HIV prevention interventions on inner-city minority high school students' levels of HIV prevention information, motivation, behavioral skills, and behavior. It involved a quasi-experimental controlled trial comparing classroom-based, peer-based, and combined classroom- and peer-based-HIV prevention interventions with a standard-of-care control condition in 4 urban high schools (N=1,532, primarily 9th-grade students). At 12 months postintervention, the classroom-based intervention resulted in sustained changes in HIV prevention behavior. This article discusses why both of the interventions involving peers were less effective than the classroom-based intervention at the 12-month follow-up and, more generally, suggests a set of possible limiting conditions for the efficacy of peer-based interventions.

Integrating Buddhism and HIV prevention in U.S. southeast Asian communities

Asian Pacific Islander communities in the United States have experienced an alarming increase in HIV infection over the past few years, possibly due to a lack of knowledge and the relative absence of appropriate educational interventions. The authors propose a new approach to the development of HIV prevention programs in U.S. southeast Asian communities. This article reviews the cultural and economic factors that may facilitate HIV transmission within these communities. Relying on the basic precepts of Buddhism, the dominant religion of many southeast Asian populations in the United States, the health belief model is utilized to demonstrate how recognizable, acceptable religious constructs can be integrated into the content of HIV prevention messages. This integration of religious concepts with HIV prevention messages may increase the likelihood that the message audience will accept the prevention messages as relevant. This nuanced approach to HIV prevention must be validated and refined through field research.     

Behavioral research in HIV/AIDS primary and secondary prevention: Recent advances and future directions.

Great advances have been made over the past decade in behavioral research on how to help persons avoid contracting HIV infections (primary prevention) and how to reduce or alleviate adverse consequences among persons who are living with HIV disease (secondary prevention). Within the primary prevention areas, research has shown the effectiveness of risk-reduction interventions undertaken with individuals, couples, small groups, communities, and at a social policy/structural level. Advances in HIV medical care have also created important new challenges and roles for behavioral scientists in the area of HIV secondary prevention. This article concludes by identifying key emerging issues in HIV behavioral research that will require attention in the years ahead. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A music-based HIV prevention intervention for urban adolescents.

Objective: This research examines the process of conducting and evaluating a music-based HIV prevention intervention among urban adolescents, and is informed by the information, motivation, behavioral skills (IMB) model. Design: Musically talented opinion leaders were recruited to write, record, and distribute HIV prevention themed music to their peers to increase HIV prevention motivation, behavioral skills, and behaviors. In this 3-month field experiment, participants were 306 students enrolled in health classes at each of three large multiracial urban high schools (one treatment school; two control schools). Main Outcome Measures: Measures of HIV prevention information, motivation, behavioral skills, and behaviors, both pre- and postintervention. Results and Conclusion: Results indicate that the intervention influenced several aspects of HIV prevention motivation, behavioral skills, and condom use and HIV testing behaviors. This research demonstrates that the incorporation of music into HIV prevention interventions for adolescents has the potential to be effective.

Effects and generalizability of communally oriented HIV-AIDS prevention versus general health promotion groups for single, inner-city women in urban clinics.

A primary prevention, behavioral intervention designed to reduce HIV risk behavior was tested in a randomized, controlled trial with single, inner-city women. A total of 935 women were randomly assigned to 1 of 3 conditions: a small group, 6-session communally oriented HIV prevention intervention; a yoked general health promotion intervention control; or a standard care control. Both interventions involved the interactive use of videotapes by live group leaders. The HIV prevention intervention, in particular, resulted in significant positive effects on self-reported and behaviorally assessed safer-sex behavior. Women in the HIV prevention group showed reduced point prevalences of medically tested sexually transmitted diseases at follow-up in some comparisons.

HIV risk correlates among non-injection cocaine dependent men in treatment

Guided by the AIDS Risk Reduction Model (ARRM), psychosocial correlates of HIV risk behavior were examined among noninjection cocaine dependent, heterosexual men (NI-CD-HM) in treatment. Subjects (N = 111) completed a structured interview to measure ARRM mediating variables and HIV risk behaviors. The results indicated that greater perceived susceptibility to contracting HIV, lower sexual self-efficacy, higher lifetime incidence of sexually transmitted diseases, and being under the influence of alcohol or other drugs during sex predicted having more sexual partners in the month prior to admission. Despite adequate knowledge of safer sex guidelines, subjects remained misinformed regarding certain aspects of HIV transmission. Men who perceived that their partners viewed condoms more positively and who exchanged drugs for sex were more likely to use condoms, yet condom use skills were typically inadequate to ensure effective prevention. These results suggest that HIV prevention interventions among NI-CD-HM should focus on improving knowledge, enhancing beliefs in the capacity to enact safer sex behaviors for preventing HIV and other STDs, building relevant skills (e.g., condom use, open sexual communication between partners), and emphasizing psychoactive substance abstinence. Couple interventions, in which partners actually rehearse safer sex negotiations, may be particularly effective in this regard.     

Effect of medicamentous cholesterol control on resources utilization in public health--significance of the Scandinavian Simvastatin Survival Study (4-S Study) for cost control in Swiss health management conditions

Upward spiralling health care expenditures have triggered the need to assess the cost-effectiveness of medical interventions. Specifically, interventions in primary and secondary prevention represent an important field of research. A resource utilization analysis was performed on the basis of the recently published Scandinavian Simvastatin Survival Study. It could be shown that treatment with simvastatin compared to placebo leads to a reduction in patient costs of CHF 8.4 million. This represents a reduction of CHF 3770.- per patient. The effective daily treatment costs can thus be calculated at CHF 1.11, which is equivalent to 36% of the actual acquisition cost per day. These results support the notion that secondary coronary prevention is not only justified from a clinical but also from an economic point of view.     

Perception of risk and sexual self-protective behavior: a methodological critique

Although several theories suggest that perceptions of the risk of transmission of sexually transmitted diseases, including HIV, motivate individuals to adopt or maintain self-protective behaviors, the research literature has generally failed to demonstrate this relationship. Because many HIV prevention interventions are based on the presumption of this relationship and because there is support for the effects of risk perception on self-protective behaviors in other health domains, a closer examination of the research concerning HIV risk perception is warranted. Therefore, a critical review of methodological features of research in this area was conducted. Issues considered were measurement; research design; the distinctive characteristics of HIV risk; the sexual and social nature of HIV transmission; and ecological, construct, and statistical conclusion validity. Methodological and design recommendations were made for testing the effects of HIV risk perception more adequately.     

Contextual community prevention theory: Building interventions with community agency collaboration.

Translation from research to practice faces numerous problems that include replicating effectiveness, fidelity to the protocol and processes, and adaptations to different types of target populations. Working collaboratively with existing service providers can speed up the time for development and can ease the implementation of empirical randomized trials. Contextual community prevention theory is an innovative approach that focuses on changing behaviors of community members by creating a visible institutional presence that draws and pulls the targeted population into the organization’s activities and interventions. The result is an institution or organization within the community that provides a new active and dynamic context, engaging its community members into its activities, interventions, and functions. An HIV prevention program developed collaboratively from the ground up for Latino gay/bisexual men is presented. Results from the program evaluation efforts across the years suggest promise for testing its efficacy through a randomized trial. HIV prevention efforts need to develop dynamic support systems within communities where these men have ownership, have control, and feel safe; otherwise HIV infection rates in this population will increase.

Can resource use be extracted from randomized controlled trials to calculate costs? A review of smoking cessation interventions in general practice

The ability to extract information on resource use from randomized controlled trials can provide the groundwork for systematically compiling health economic reviews of health interventions. A review of the brief smoking interventions in general practice demonstrates that not all the necessary information can be extrapolated from these trials, and cost data will have to be supplemented from other sources.     

Psychological interventions with AIDS and HIV: Prevention and treatment.

In the decade since AIDS was first diagnosed, behavioral research has focused intensively on risk reduction change processes and, to a lesser extent, on mental health needs of persons with HIV conditions. Although research to date has yielded important findings for primary prevention efforts and has identified some psychological dimensions relevant to mental health interventions, there is a pressing need for much more systematic intervention outcome research in both the prevention/behavior change and emotional coping areas. Progress in these areas will be facilitated by better linkage of intervention approaches to behavioral theory; identification of intervention elements that produce HIV risk behavior change; evaluated field-testing of promising intervention models; continued focus on populations that remain at risk (such as gay men and iv drug users); and expansion of prevention efforts to urban, poor, and minority populations increasingly threatened as AIDS/HIV enters a "2nd wave." Although AIDS is still a relatively new problem, existing behavioral medicine conceptual models and intervention strategies can be adapted to meet the enormous challenges created by AIDS and HIV infection.

Laser-assisted hair removal

Primary care physicians continue to play an important role in preventing HIV transmission by targeting messages to their high-risk patients. The risk of HIV transmission cannot be eliminated entirely; however, clinicians have a variety of prevention interventions at their disposal. Behavioral and therapeutic interventions offered in a client-centered environment have the greatest chance of success. Patients can benefit from individualized prevention plans that decrease risk by treating drug addiction and by modifying sexual and drug-taking behaviors. The risk of HIV infection in health care workers can be reduced by strict adherence to universal precautions and the use of postexposure antiretroviral therapy.     

Prevention indicators for evaluating the progress of national AIDS programmes

Major interventions to reduce HIV transmission involve increasing knowledge about preventing HIV transmission for sustained behavioral changes; and enhancing the control of sexually transmitted diseases (STD), which increase the probability of HIV transmission. Activities have also been developed to prevent the transmission of HIV by blood, donor selection, and more rational use of transfusions. Behavioral changes among injecting drug users have also been promoted. Recommendations are made for the evaluation of AIDS programs, focusing on prevention of sexual transmission of HIV, and outlining the approach developed by the Global Program on AIDS (GPA; Geneva, Switzerland) for use by national programs. Based on the feasibility, accuracy, reliability and validity of the quantitative assessment of programs, 10 indicators of progress and outcomes of prevention activities have been developed by GPA. These include indicators of population knowledge regarding preventive practices, reported sexual behavior and use of condoms in the general population, STD service evaluation, and indicators of program impact. The latter are measured through the reported STD incidence in the general male population, and syphilis and HIV prevalence in women. The four methods are proposed for measuring the 10 core prevention indicators (PI). Five PIs are measured during a population survey: reported knowledge of preventive practices (PI-1), condom availability at peripheral level (PI-3), reported frequency of nonregular sexual partners (PI-4), reported condom use during nonregular sexual encounters (PI-5), and reported STD incidence among men (PI-9). Condom availability at central level (PI-2) is assessed through key-informant interviews with major distributors. Structured health facility surveys allow assessment of the appropriateness of STD case management (PI-6 and PI-7). A serosurvey among antenatal clinic attenders aged 15-24 years allows the measurement of HIV and syphilis seroprevalence in that population (PI-8 and PI-10). GPA recommends that such surveys be repeated after a period of 1 to several years.     

Cost-effectiveness of improved treatment services for sexually transmitted diseases in preventing HIV-1 infection in Mwanza Region, Tanzania

Improved management of sexually transmitted diseases (STDs) is consistently advocated as an effective strategy for HIV prevention. The impact, cost, and cost-effectiveness of this approach were evaluated in a prospective, comparative study of six communities in Tanzania's Mwanza Region in which primary health care center workers were trained to provide improved STD treatment and six matched non-intervention communities. The baseline prevalence of HIV was 4% in both groups. During the 2-year study period, 11,632 cases of STDs were treated in the intervention health units. The HIV seroconversion rate was 1.16% in the intervention communities and 1.86% in the comparison communities--a difference in HIV incidence of 0.70 (95% confidence interval, 0.37-1.09) and a reduction of about 40%. The total annual cost of the intervention was US$59,060 ($0.39 per person served). The cost of STD treatment was $10.15 per case. An estimated 252 HIV-1 infections were averted each year. The incremental annual cost of the program was $54,839, equivalent to $217.62 per HIV infection averted and $10.33 per disability-adjusted-life-year (DALY) saved. The estimated cost-effectiveness compares favorably with that of childhood immunization programs ($12-17 per DALY saved) and could be further enhanced through implementation of the intervention on a wider scale. The intervention subsequently has been expanded to encompass 65 health units in Mwanza Region, with no increase in investment costs.     

Implications of HIV treatment advances for behavioral research on AIDS: Protease inhibitors and new challenges in HIV secondary prevention.

Protease inhibitor combination therapies can reduce HIV viral load, improve immune system functioning, and decrease mortality from AIDS. These medical developments raise a host of critical new issues for behavioral research on HIV/AIDS. This article reviews developments in HIV combination therapy regimens and behavioral factors involved in these regimens and focuses on four key behavioral research areas: (a) the development of interventions to promote treatment adherence, (b) psychological coping with HIV/AIDS in the context of new treatments for the disease, (c) the possible influence of treatment on continued risk behavior, and (d) behavioral research in HIV prevention and care policy areas. Advances in HIV medical care have created important new opportunities for health psychologists to contribute to the well-being of persons with HIV/AIDS.

STD/HIV prevention in Turkey: planning a sequence of interventions

This study was initiated to assess which mix of early STD/HIV prevention interventions would potentially be effective, cost-effective and sustainable in Turkey; and to program an intervention sequence to maximize synergy among the interventions. During rapid assessment we: 1) reviewed past issues of 3 leading newspapers; 2) collected information on TV coverage; 3) interviewed key informants including taxicab drivers, hotel employees, grocery store owners, academicians in public health and law, investigators of STD/HIV and reproductive tract infections, and officials in the ministry of health; 4) reviewed available evidence on STD/HIV morbidity, sexual behavior patterns, migration patterns and same/opposite gender sex trade. We found: 1) discrepancies between decision makers' perceptions and social realities with respect to the epidemiology of sexual behavior and STDs, and the state of public health programs; 2) discrepancies between sexual practices and public expression regarding sexual practices; 3) economic, demographic, and political pressures in Turkey and in surrounding countries for the expansion of prostitution; 4) a sexual double standard and gender specific migration patterns which sustain a high demand for commercial sex; 5) patterns of health care seeking behaviors and provision of STD clinical services which indicate other STDs may play a very important role in spread of HIV infection; 6) an important mass media role in opinion formation; 7) consensual denial of risk for the majority based on beliefs embedded in machismo, nationalism and religion, and a resulting marginalization and externalization of STD/HIV risk; 8) high prevalence of syphilis among both Turkish and immigrant female prostitutes in Istanbul (early latent 8 and 13%; late latent 0 and 4%; previous history 9 and 22%) 9) and high rates of syphilis among male prostitutes (early latent 11%, late latent 21% and previous history 58%). We concluded that interventions should initially include, in the following order; 1) awareness raising for decision makers and opinion leaders including members of parliament and mass media; 2) awareness raising for members of the general population; 3) needs assessment and intervention development for sex workers; 4) training in HIV and other STDs for medical personnel; and 5) quality assurance and control for laboratory procedures for STDs/HIV.
