Impact of a longitudinal community HIV intervention targeting injecting drug users' stage of change for condom and bleach use

Promoting Safe Injection Practices, Substance Use Reduction, Hepatitis C Testing, and Overdose Prevention Among Syringe Service Program Clients Using a Computer-Tailored Intervention: Pilot Randomized Controlled Trial

BACKGROUND

Syringe service programs (SSPs) are safe, highly effective programs for promoting health among people who inject drugs. However, resource limitations prevent the delivery of a full package of prevention services to many clients in need. Computer-tailored interventions may represent a promising approach for providing prevention information to people who inject drugs in resource-constrained settings.

OBJECTIVE

The aim of this paper is to assess the effect of a computer-tailored behavioral intervention, called Hep-Net, on safe injection practices, substance use reduction, overdose prevention, and hepatitis C virus (HCV) testing among SSP clients.

METHODS

Using a social network-based recruitment strategy, we recruited clients of an established SSP in Wisconsin and peers from their social networks. Participants completed a computerized baseline survey and were then randomly assigned to receive the Hep-Net intervention. Components of the intervention included an overall risk synthesis, participants' selection of a behavioral goal, and an individualized risk reduction exercise. Individuals were followed up 3 months later to assess their behavior change. The effect of Hep-Net on receiving an HCV screening test, undergoing Narcan training, reducing the frequency of drug use, and sharing drug equipment was assessed. The individual's readiness to change each behavior was also examined.

RESULTS

From 2014 to 2015, a total of 235 people who injected drugs enrolled into the Hep-Net study. Of these, 64.3% (151/235) completed the follow-up survey 3-6 months postenrollment. Compared with the control group, individuals who received the Hep-Net intervention were more likely to undergo HCV testing (odds ratio [OR] 2.23, 95% CI 1.05-4.74; P=.04) and receive Narcan training (OR 2.25, 95% CI 0.83-6.06; P=.11), and they shared drug equipment less frequently (OR 0.06, 95% CI 0.55-0.65; P<.001). Similarly, individuals who received the intervention were more likely to advance in their stage of readiness to change these 3 behaviors. However, intervention participants did not appear to reduce the frequency of drug use or increase their readiness to reduce drug use more than control participants, despite the fact that the majority of the intervention participants selected this as the primary goal to focus on after participation in the baseline survey.

CONCLUSIONS

Implementing computer-based risk reduction interventions in SSPs may reduce harms associated with the sharing of injection equipment and prevent overdose deaths; however, brief computerized interventions may not be robust enough to overcome the challenges associated with reducing and ceasing drug use when implemented in settings centered on the delivery of prevention services.

HIV Risk-Reduction Strategies for Substance Abusers: Effecting Behavior Change

Substance abuse has a strong link to HIV/AIDS in the United States. Use and abuse of alcohol and other drugs often reduce inhibitions and encourage engagement in high-risk sexual behaviors that can ultimately result in HIV and AIDS. The HIV/AIDS epidemic in the United States has disproportionately affected minorities with African Americans being the group hardest hit. This article presents some of the behavioral, social, and psychological factors that influence the risk for drug use. It highlights and assesses the effectiveness of HIV risk-reduction strategies developed for drug-using populations and makes recommendations for a more holistic and integrated approach utilizing multiple interventions at multiple levels.

Changing health-promoting behaviours through narrative interventions: A systematic review

The objective of this review was to summarize the literature supporting narrative interventions that target health-promoting behaviours. Eligible articles were English-language peer-reviewed studies that quantitatively reported the results of a narrative intervention targeting health-promoting behaviours or theoretical determinants of behaviour. Five public health and psychology databases were searched. A total of 52 studies met inclusion criteria. In all, 14 studies found positive changes in health-promoting behaviours after exposure to a narrative intervention. The results for the changes in theoretical determinants were mixed. While narrative appears to be a promising intervention strategy, more research is needed to determine how and when to use these interventions.

Adapting effective narrative-based HIV-prevention interventions to increase minorities' engagement in HIV/AIDS services

Disparities related to barriers to caring for HIV-positive and at-risk minorities continue to be a major public health problem. Adaptation of efficacious HIV-prevention interventions for use as health communication innovations is a promising approach for increasing minorities' utilization of HIV health and ancillary services. Role-model stories, a widely-used HIV-prevention strategy, employ culturally tailored narratives to depict experiences of an individual modeling health-risk reduction behaviors. This article describes the careful development of a contextually appropriate role model story focused on increasing minorities' engagement in HIV/AIDS health and related services. Findings from interviews with community members and focus groups with HIV-positive minorities indicated several barriers and facilitators related to engagement in HIV health care and disease management (e.g., patient-provider relationships) and guided the development of role-model story narratives.

Stages of consistent condom use, partner intimacy, condom use attitude, and self-efficacy in African-American crack cocaine users

This study examined how condom use attitude, self-efficacy, and partner intimacy related to five stages of consistent condom use. Interview data were collected from sexually active, heterosexual, African-American crack cocaine smokers (N = 366). Dependent measures assessed both the participants' own responses and their perceptions about their last sex partner's own personal condom use attitude and participants' condom use self-efficacy expectations. Partner intimacy was assessed both as a continuous attitudinal and as a discrete relationship measure. Less than 10% were classified as consistent condom users. Two thirds of inconsistent users were in the Precontemplation (PC) stage. The contemplation (C) and preparation (P) stages were equal among the remainder of the inconsistent condom users. Higher partner intimacy reduced modestly readiness for consistent condom use. The stage but not the intimacy group was related to the condom use attitudes and self-efficacy measures. Last partners' perceived own negative attitudes were significantly related to the stages of consistent condom use and was especially low in the action (A) and maintenance (M) stages. Participants' own negative attitudes were unrelated to the stages. Of the self-efficacy measures, both participants' performance and situational condom use self-efficacies increased significantly after the PC stage and were highest in the P, A, and M stages. However, situational self-efficacy accounted for most of performance self-efficacy variance. In sum, consistent condom use was rare. A partner's attitudes and the participants' own situational self-efficacy expectations, rather than intimacy, determined the readiness to adopt consistent condom use.

Epidemiology of recreational drug toxicity in a nightclub environment

Data on 173 individuals with recreational drug toxicity requiring "medical" assistance in a large urban nightclub was collected from September 2007 to January 2008. Clubbers required assistance following use of a variety of recreational drugs, particularly gamma-hydroxybutyrate (GHB), gammabutyrolactone (GBL), and ketamine. The majority of individuals were not first-time recreational drug users, and a significant proportion have recurrent recreational drug toxicity requiring assistance. Limitations related to data collection are discussed. Further studies are needed to investigate the use brief interventions in those with problem recreational drug use within the nightclub environment.

A process evaluation of the implementation of a computer-based, health provider-delivered HIV-prevention intervention for HIV-positive men who have sex with men in the primary care setting

There is increasing interest in using healthcare providers to deliver HIV-prevention services to their patients. Unfortunately, lack of counselling skills and time constraints within busy clinics serve as barriers to such efforts. The Providers Advocating for Sexual Health Initiative (PASHIN) study used state-of-the-art computer technology to assess each participant's risk behaviours and to determine the patient's readiness for changing each behaviour. The computer synthesized the participant-entered data, determined the targeted risk behaviour and printed a behavioural theory-based provider advice sheet and a 3-point patient prescription for the targeted risk behaviour. Since the intervention does not require providers to spend time performing a detailed sexual-risk assessment and it does not require providers to have received extensive counselling training, it has the potential to minimize some of the barriers associated with provider-delivered interventions. Thus, the purpose of this process evaluation was to assess how the PASHIN intervention was implemented in the field, including issues such as the fidelity of implementation and health providers' views on and experience with implementing the intervention. Overall, the results demonstrated that the computer-based, provider-delivered intervention was successfully delivered by providers within the context of regularly scheduled treatment sessions with HIV-positive men who have sex with men (MSM) patients. The majority of providers (79.4%) and patients (83.5%) reported that the quality of HIV-prevention services delivered during these sessions was 'good'. The majority of the providers also reported that they had received adequate training, felt more confident in communicating HIV-prevention issues with their patients and provided more HIV-prevention counselling to their patients, due to the project. However, the experience of delivering HIV-prevention counselling during an 18-month period did not appear to change providers' attitudes toward a provider-delivered HIV-prevention intervention nor their belief in the effectiveness of HIV prevention in general. Future studies should focus on how to enhance providers' acceptance and commitment to delivering HIV-prevention counselling to their patients during the clinic visit.

Self-efficacy scale for Pap smear screening participation in sheltered women

BACKGROUND

Sheltered, homeless women disproportionately experience cervical dysplasia and cervical cancer. Low rates of Pap smear screening contribute to late diagnosis with accompanying increased morbidity and mortality. Self-efficacy (SE) has been demonstrated to be predictive of several health behaviors, but limited evidence about SE for Pap smear screening exists.

OBJECTIVES

To develop, test, and refine the conceptually based Self-Efficacy Scale for Pap Smear Screening Participation (SES-PSSP).

METHODS

This correlational, descriptive study included a purposive sampling of sheltered women (N = 161).

RESULTS

The 20-item SES-PSSP demonstrated acceptable initial validity and reliability. Reliability estimates of stability (>or=84%) and internal consistency (alpha = .95) exceeded criteria. Content validity and construct validity were supported (e.g., common factor analysis and predictive model testing that included SE, decisional balance, knowledge regarding Pap smear screening, demographics, health-related behaviors, health status, and personal beliefs about risks for cervical cancer and dysplasia). Self-efficacy, decisional balance, illicit drug usage, and age predicted 28% of the variance in stages of change (precontemplation, contemplation, preparation, action, and maintenance) for Pap smear screening participation.

DISCUSSION

The SES-PSSP provides a new scale for measuring SE pertinent to Pap smear screening participation in a vulnerable, ethnically diverse sample of sheltered, inner-city women. Validity testing demonstrated that the SE concept was predictive of Pap smear screening behavior, suggesting that SE-based interventions tailored to the SES-PSSP subscale or total scores could increase screening. A 10-minute completion time supports feasibility for use in the clinic setting.

Sexual Risk Among Injection Drug Users Recruited From Syringe Exchange Programs in California

OBJECTIVE

The objective of this study was to examine correlates of sexual risk among injection drug users (IDUs).

STUDY

A total of 1445 IDUs were recruited from California syringe exchange programs.

RESULTS

Consistent condom use was independently related to being HIV-positive, having multiple sex partners, not having a steady partner, not sharing syringes, and not injecting amphetamines for men; and engaging in sex work, not sharing syringes, and not having a steady partner for women. Having multiple recent sexual partnerships that included a steady partner was related to engaging in sex work, speedball injection, and amphetamine use among men; and younger age, having had a sexually transmitted disease (STD), engaging in sex work, and using alcohol among women. Having heterosexual anal sex was related to having had an STD, having multiple sexual partners, using amphetamines, and syringe-sharing for men; and younger age and amphetamine use for women.

CONCLUSIONS

Comprehensive prevention interventions addressing multiple sexual and injection risk behaviors are needed for IDUs.

Toward an ecstasy and other club drug (EOCD) prevention intervention for rave attendees

A growing body of recent research has identified that "rave" attendees are at high risk for the use of "club drugs," such as 3,4-methylenedioxymethamphetamine (MDMA or "ecstasy"). Rave attendees, however, comprise only one of several club-going populations. In the current study, we explore the prevalence of ecstasy and other club drug (EOCD) use among a sample of club attendees in Washington, DC. Data were collected from adult, primarily homosexual, club attendees during the summer of 2003. Data collection was scheduled between 11 p.m. and 3 a.m. Participation rates were high. Of the 211 club attendees approached, 88% (n = 186) completed the interview. Drug use prevalence rates were low. With the exception of alcohol and marijuana, 2-day self-reports were less than 1% for each drug. These findings, amalgamated with results from other EOCD-related studies involving several distinct populations, offer considerable insight into the state of ecstasy in American society. Based on a meta-analysis of this literature, we offer a community-level prevention intervention for the population at highest risk for EOCD use-rave attendees.

Challenges facing health professionals caring for HIV-infected drug users

Although injection drug use accounts for only 5% to 10% of cumulative HIV infections globally, it is a more efficient way of spreading HIV than sexual intercourse. HIV epidemics among injection drug users (IDUs) have a potential for rapid spread of the virus within the IDU community and outward into the general population. Effective interventions addressing this mode of HIV transmission are needed because part of a comprehensive strategy to curb the spread of HIV infection. IDUs, often marginalized, pose serious health challenges that can no longer be overlooked. Health care providers need to familiarize themselves with these challenges in order to meet the needs of this disenfranchised population. Providers need to have a clear understanding of targeted behavior and their patients' environmental context. Efforts must be made to foster healthy behavior among IDUs to assist them in managing their infection effectively and become productive members of society. This paper reviews these challenges and outlines selected models that may assist health care providers in fostering behavior changes among HIV-positive injection drug users.

Stress and transtheoretical model indicators of stress management behaviors in HIV-positive women

OBJECTIVE

Women are particularly prone to stress with respect to living with HIV. Stress management behaviors can mediate the stress response and improve health outcomes in HIV-positive individuals. The purpose of this descriptive cross-sectional study was to examine stress and Transtheoretical Model (TTM) indicators of stress management behaviors in HIV-positive women.

METHODS

126 HIV-positive women recruited from diverse HIV-care clinics in northeast Ohio completed standardized self-report research instruments to measure stress, stress management behaviors, stage of change, self-efficacy, and decisional balance (pros and cons).

RESULTS

Women reported higher levels of stress in the later phase of HIV infection (P<.05). Highly stressed women in this study reported infrequently using stress management behaviors and a low level of perceived efficacy to manage stress although they perceived the pros of managing stress to be high (P<.01). Stress management behaviors were significantly related to stage of change (P<.01), self-efficacy (P<.01), and the cons of managing stress (P<.05). Graphed patterns of decisional balance examined by stage of change and stress management behavior were atypical in this sample.

CONCLUSIONS

Clinicians and researchers can use the TTM to describe behavioral indicators of stress management in HIV+ women. However, further research is needed to more fully understand behavioral processes HIV+ women can use to adopt and maintain stress management behaviors.

Integrating behavior change theory into geriatric case management practice

Case management practices have continued to grow despite a lack of clear evidence of their efficacy. With the expanding segment of the elderly population, there is a critical need to develop and identify programs that will address the many needs of the aging. Geriatric Case Management has been the avenue selected by many health care providers to address these issues, focusing on maintaining health status and improving linkages with medical and community resources. Studies testing the effectiveness of these models have failed to demonstrate their effectiveness in reducing depression, reducing acute care service use, and improving or maintaining health status. The Geriatric Case Management models presented in these lack an evidence-based, theoretical framework that provides definition and direction for case management practice. This article introduces behavior change theories as a method of structuring and delineating the case management intervention. The Transtheoretical Model and the Theory of Planned Behavior are discussed and methods of integrating these theories into practice are discussed.

Needle and syringe cleaning practices among injection drug users

Bleach-mediated disinfection (BMD) of needles and syringes (NS) has been advocated as a risk-reduction intervention against HIV among injection drug users (IDUs). The effect of needle exchange on the BMD practices of 176 NS-sharing IDUs was evaluated. IDUs were randomly assigned to either 1) Pharmacy Sales Condition, access to NS via legal sales of nonprescription NS; or 2) Needle Exchange Condition, with additional access to NS via an experimental needle exchange program. Repeated measures analysis revealed a main effect of time on BMD, no effect of assignment condition, and no time by assignment interaction. Logistic regression revealed IDUs who traded sex for money or drugs were less likely to practice BMD, and IDUs who reported a reduced number of sex partners were more likely to practice BMD. Future interventions should incorporate behavioral BMD components and address the concerns of those who trade sex for money or drugs.

Readiness to change: newspaper coverage of tobacco farming and diversification

Diversification, like tobacco use prevention and cessation, is an important public health concern. The multilevel patterns of tobacco dependency suggest the need for public health approaches to the "tobacco problem." To understand how newspaper and wire service journalists cover issues involving diversification among tobacco farmers, the authors performed a content analysis of a subset of 100 articles on diversification and tobacco farming. Prochaska and DiClemente's stages of change model was applied to the "problem behavior" of tobacco farming. Among news accounts relating to tobacco farmers or tobacco farming, print media accounts gave relatively little attention to the issue of diversification. Farmers in the sample of news accounts were generally cognizant of pressures to diversify away from reliance on tobacco cultivation but were frustrated due to obstacles to diversification such as limited diversification options and relative absence of infrastructure supports. Community leaders and policy-relevant sources generally supported diversification.

STAND: a peer educator training curriculum for sexual risk reduction in the rural South. Students Together Against Negative Decisions

BACKGROUND

The incidence of AIDS in rural areas continues to increase rapidly, with teenagers continuing to report high rates of sexual risk behaviors. Unfortunately, there is a dearth of effective HIV prevention programs targeting youth in rural settings where there are often formidable barriers to sex education programs. This paper describes a theoretically based intervention designed to meet the needs of rural youth.

METHODS

Students Together Against Negative Decisions (STAND) is a 28-session teen peer educator training program implemented in a rural county in a southeastern state, promoting both abstinence and sexual risk reduction. The theoretical foundation of the curriculum includes both Diffusion of Innovations Theory and the Transtheoretical Model, focusing on both individual and community norm change. STAND is teen-centered and skills-based; activities focus on active learning. Educator trainees are selected on the basis of their opinion leadership within their peer group, resulting in a training group of both virgin and sexually active teens, balanced for gender and matched to the racial proportions of the school.

RESULTS

Acceptance and participation in STAND suggest that adolescents in rural communities can be accessed through community-based interventions, that they are willing to participate in such intensive programs, and that they perceive the intervention as valuable and enjoyable. Moreover, the STAND program has thrived in a relatively conservative rural environment, and has had a positive impact on adolescents' sexual risk taking. Results from a pilot study showed significantly greater increases in condom use self-efficacy (16% vs a 1% decrease among controls) and in consistent condom use (+28% vs +15%). Adolescent trainees also reported a sevenfold larger increase in condom use (+213% vs +31%) and a 30% decrease in unprotected intercourse compared to a 29% increase among controls.

CONCLUSIONS

STAND represents a new genre of HIV prevention program, one that utilizes complementary theoretical models to develop a program that targets both individual- and community-level change for rural adolescents.

The utility of the Transtheoretical Model of behavior change for HIV risk reduction in injection drug users

The spread of HIV among injection drug users (IDUs) is the second most common mode of transmission next to sexual contact. Although HIV infections can be prevented by changing high-risk behaviors such as needle sharing, these high-risk behaviors are highly complex. Initially developed for smoking cessation, Prochaska's Transtheoretical Model (TTM) is well-suited to the IDU population because it recognizes that chronic behavior patterns are usually under some combination of biological, social, and self-control. The objective of this article is to examine the utility of the TTM for promoting risk reduction behaviors among IDUs. This article will outline (a) the challenges of applying the TTM to IDU behaviors with respect to HIV prevention, (b) the four major components of the TTM as they relate to IDUs, (c) how risk reduction practitioners are currently using the TTM, and (d) current and future research using the TTM.

Evaluation of the effects of outreach to women with multiple vulnerabilities on entry into substance abuse treatment

This paper examines ways in which the level of participation in intensive outreach contributes to entry into substance abuse treatment. It was hypothesized that the number of outreach contacts to substance abusing women predicts the likelihood of their entry into drug abuse treatment. As such women often have multiple vulnerabilities that impact upon their needs and readiness for seeking treatment, we also examine the relationships among readiness to seek assistance, the women's level of involvement with the outreach project, and admission to treatment. A sample of 665 women who participated in an enhanced outreach and treatment readiness preparation program was tracked to examine patterns of referral and entry into substance abuse treatment. The number of outreach contacts was inversely related to receiving referrals to substance abuse treatment, as well as to the completion of those referrals (for a subsample of 551 women who had received referrals). In addition, victims of domestic violence were 50% more likely to receive a referral to drug abuse treatment, but of the women who received such a referral, the lack of involvement in a violent relationship predicted entry into treatment. Findings are discussed in terms of their implications for designing and implementing outreach and treatment programs for women with multiple therapeutic issues, particularly substance abuse and domestic violence.
