Abstract

BACKGROUND: Hepatitis C virus (HCV) is a major health problem among injection drug users (IDU). One potential means of reducing risk of HCV transmission among IDU is serosorting, whereby IDU preferentially share injection equipment with persons of like HCV status. METHODS: We surveyed Seattle area IDU recruited by respondent-driven sampling as part of the National HIV/AIDS Behavioral Surveillance system in 2005. RESULTS: Of 337 participants, 91% reported ever having been tested for HCV. Fifty-three percent of participants who shared any injection ...

Abstract

Abstract  The Sexual Acquisition and Transmission of HIV Cooperative Agreement Program (SATHCAP) examined the role of drug use in the sexual transmission of the human immunodeficiency virus (HIV) from traditional high-risk groups, such as men who have sex with men (MSM) and drug users (DU), to lower risk groups in three US cities and in St. Petersburg, Russia. SATHCAP employed respondent-driven sampling (RDS) and a dual high-risk group sampling approach that relied on peer recruitment for a combined, overlapping sample of MSM ...

Abstract

Bridge populations can play a central role in the spread of human immunodeficiency virus (HIV) by providing transmission links between higher and lower prevalence populations. While social network methods are well suited to the study of bridge populations, analyses tend to focus on dyads (i.e., risk between drug and/or sex partners) and ignore bridges between distinct subpopulations. This study takes initial steps toward moving the analysis of sexual network linkages beyond individual and risk group levels to a community level in ...

Abstract

Abstract  The purpose of the study was to determine the potential contribution of bisexual men to the spread of HIV in Los Angeles. We compare the characteristics and behaviors of men who have sex with men and women (MSMW) to men who have sex with only women (MSW) and men who have sex with only men (MSM) in Los Angeles. Men (N = 1,125) who participated in one of the two waves of data collection from 2005 to 2007 at the Los Angeles site ...

Abstract

AIMS: We explore the mechanisms by which 'partnership-level' variables--the mix of characteristics of individuals who inject drugs together--affect the incidence of HIV risk behaviors, including receptive syringe sharing, and facilitate or impede the spread of HIV. DESIGN: We apply multivariate analysis techniques to data on injection partnerships (pairs of individuals who inject drugs together) collected using a network sample of 401 African-American IDUs in Washington, DC. FINDINGS: Drug injectors tended to select injection partners of the same gender and similar age, ...

Abstract

This ethnographic account of a night spent in an African-American heroin shooting gallery in East Harlem, present the details of how heroin, cocaine and crack are bought, injected, enjoyed and suffered on New York City's most dangerous streets. Although the narrative spans only one ten-hour session, it builds upon the author's many years of participant-observation research among drug dealers and addicts. The observations and conversations evoke the roller coaster agonies and ecstasies of heroin and cocaine addiction. They also highlight the ...

Abstract

A theoretical understanding of the gendered contours of structural, everyday and symbolic violence suggests that young addicted women are particularly vulnerable to the infectious diseases caused by injection drug use-especially hepatitis C. Participant-observation fieldwork among heroin and speed addicts in San Francisco's Haight Ashbury neighborhood reveals that extreme levels of violence against women are normalized in the common sense of street-youth drug culture. Physical, sexual and emotional violence, as well as the pragmatics of income generation, including drug and resource sharing ...

Abstract

BACKGROUND: Street-based heroin injectors represent an especially vulnerable population group subject to negative health outcomes and social stigma. Effective clinical treatment and public health intervention for this population requires an understanding of their cultural environment and experiences. Social science theory and methods offer tools to understand the reasons for economic and ethnic disparities that cause individual suffering and stress at the institutional level. METHODS AND FINDINGS: We used a cross-methodological approach that incorporated quantitative, clinical, and ethnographic data collected by two ...

Abstract

Abstract  This study determined whether homeless injection drug users (IDUs) were more likely than stably housed IDUs to engage in HIV-associated risk behaviors. Respondent driven sampling was used to recruit 343 African American male IDUs. About 69% of men had been homeless in the past year and 13% were HIV positive. Controlling for age and income, homeless men as compared to stably housed men were 2.6 times more likely to report sharing needles, 2.4 times more likely to have 4 or more ...

Abstract

Abstract  A number of sampling methods are available to recruit drug users and collect HIV risk behavior data. Respondent-driven sampling (RDS) is a modified form of chain-referral sampling with a mathematical system for weighting the sample to compensate for its not having been drawn randomly. It is predicated on the recognition that peers are better able than outreach workers and researchers to locate and recruit other members of a “hidden” population. RDS provides a means of evaluating the reliability of the data ...

Abstract

Increasingly, respondent-driven sampling (RDS) is being applied to study not-in-treatment users of illicit drugs. Although RDS has been successfully applied in recruiting active users in densely-populated, metropolitan areas, its utility with hidden populations in rural areas has yet to be determined. This study critically evaluates the sample of not-in-treatment, illicit stimulant drug users (n = 249) recruited from the application of RDS in three rural counties in west-central Ohio. The findings of this study largely support the results of earlier studies in urban ...

Abstract

Recruiting samples that are more representative of illicit drug users is an on-going challenge in substance abuse research. Respondent-driven sampling (RDS), a new form of chain-referral sampling, is designed to eliminate the bias caused by the non-random selection of the initial recruits and reduce other sources of bias (e.g. bias due to volunteerism and masking) that are usually associated with regular chain-referral sampling. This study provides a methodological assessment of the application of RDS among young adult MDMA/ecstasy users in Ohio. ...

Abstract

Abstract  This study used a modified version of the Behavioral Model for Vulnerable Populations to examine the predisposing, enabling, and need factors associated with detectable viral load (VL). HIV status was measured using saliva and confirmed by blood. Of 797 persons enrolled, 193 were HIV positive and provided VL counts. A hierarchical multivariate logistic regression approach demonstrated that the predisposing factors of homelessness and recent substance abuse, particularly methamphetamine abuse, had a negative association with VL. The negative association of homelessness on ...

Abstract

Greg Scott's paper, "[`]They got their program, and I got mine": a cautionary tale concerning the ethical implications of using respondent-driven sampling to study injection drug users' (Scott, 2008) is seriously flawed by (1) a near complete lack of context in assessing ethical implications of respondent-driven sampling, (2) ignoring the ethnographer's impact on what is observed, (3) a seemingly bedrock belief that the intimacy of ethnographic interviews produces truth, and (4) a misreading of power relationships. Some scenarios depicted in the ...

Abstract

Serious methodological and ethical flaws are detailed in an ethnographic study of a respondent-driven sampling (RDS) project for drug users in Chicago. The study is also disconnected from the larger social context within which the project operated, and from the existing literature on human-subject problems the author claims he "discovered" about RDS - problems common to traditional outreach projects that researchers have known about and managed successfully for years. Due to an admitted bias in the author's sampling, and an eagerness ...

Abstract

BACKGROUND: This article examines the ethical implications of using respondent-driven sampling (RDS) to conduct HIV behaviour surveillance among injection drug users (IDUs) in Chicago. Ethnographic inquiry illustrates how the design and implementation of RDS invites if not promotes manifold violations of federal guidelines governing human research subject protections. METHODS: Post hoc structured interviews with approximately 13% (n=70) of the behaviour surveillance sample (N=529) focused on how RDS's "dual incentive" structure affected participants' social, economic, and cultural milieu. Triangulated methods include interviews ...
