  • Article: Perceptions of HIV risk among monogamous wives of alcoholic men in South India: a qualitative study.
    [show abstract] [hide abstract]
    ABSTRACT: To understand women's perceptions of their own HIV risk and to determine the feasibility of conducting an HIV prevention study. Two focus groups were conducted in November 2004 with wives of heavy drinkers admitted to the Deaddiction Unit at the National Institute of Mental Health and Neurosciences (NIMHANS) in Bangalore, India. Data were analyzed using content analysis. Results focused on (1) awareness of the women regarding HIV/AIDS and condom use, (2) perception of personal risk for HIV/AIDS and the risk of their spouses, and (3) the feasibility of a future community-based HIV prevention study. Focus group findings indicated that although the majority of the women were aware of HIV/AIDS, there were important misconceptions about the mode of transmission. Women acknowledged the potential risk for HIV associated with their spouse's drinking, as well as their extramarital sexual activities, but expressed an inability to negotiate safer sex behaviors, such as condom use, within the context of marriage. This was often expressed as fear of being physically abused for attempting such negotiations. All women agreed that the HIV prevention study we proposed, originally developed in the West, would be acceptable if tailored to specific local needs. The women provided valuable suggestions for the effective implementation of the study. The findings of this study indicate a critical need to develop culturally relevant HIV prevention programs directly targeted to wives that equip them with effective skills to negotiate safer sex behaviors with their spouses.

  • Article: Enrolling, Retaining, and Benefiting Out-of-Treatment Drug Users in Intervention Research.
    [show abstract] [hide abstract]
    ABSTRACT: LONGITUDINAL RESEARCH ON street-recruited out-of-treatment drug users involves ethical issues concerning enrollment and retention of participants, remuneration and benefits. In contrast to practices of excluding such high-risk populations from research and assuming that they would not comply with a protocol requiring repeated measures over a 12-month period, this report presents examples from 15 years of community-based studies that have enrolled drug-using participants and achieved a 96% retention rate. We also examine ethical issues connected with cash remuneration, and describe methods to elucidate the kinds of benefits that are most meaningful to this population. Findings suggest that the research community must reconsider the ethics of blanket exclusions of such high-risk subjects, and make evidence-based decisions about recruitment, retention, remuneration, and benefits.

  • Article: Dinosaur girls, candy girls, and Trinity: voices of Taiwanese club drug users.
    [show abstract] [hide abstract]
    ABSTRACT: Research among Asian users of methylenedioxy methamphetamine (MDMA), also known as Ecstasy, is rare. To evaluate the feasibility of a study on the abuse of and dependence on Ecstasy, two focus groups of users (n= 12) and health professionals (n=7) were conducted in Taiwan. Major results included blatant human testing with "candy and dinosaur girls" and a specific sequence of drugs called a "Trinity" (Ecstasy, ketamine, and marijuana). "Head-shaked bars" and "KTVs" were public places where illegal behaviors were implicitly allowed. Depression after Ecstasy use was not reported. For future studies, participants suggested that magnetic resonance imaging could be a strong incentive for young users to enhance willingness to participate. Cultural issues of Ecstasy use are also discussed.

  • Article: Problem gambling and violence among community-recruited female substance abusers.
    [show abstract] [hide abstract]
    ABSTRACT: Problem gambling (PG) may be associated with depression, victimization, and violence characterizing a substance-abusing lifestyle. The study explored associations of PG with these correlates among heavy-drinking and drug-using out-of-treatment women recently enrolled in 2 National Institutes of Health-funded, community-based HIV prevention trials. Female substance abusers with PG (n = 180) and without PG (NPG; n = 425) were examined according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). Whereas PGs had higher rates of each correlate than did NPGs, significant associations existed for antisocial personality disorder, specifically for violent tendencies. Logistic regression indicated that substance abusers with violent tendencies were about 3 times as likely as those without such tendencies to be PGs, after controlling for sociodemographics. Future research addressing whether underlying constructs, confounding variables, or interactions exist will further specify PG risk and inform prevention and intervention efforts.

    Article: The effects of childhood trauma on sex trading in substance using women.
    [show abstract] [hide abstract]
    ABSTRACT: This article presents a model developed to understand the relationship between childhood victimization, perpetration of violence, and later cocaine dependence and adult sex trading among drug using women. A cohort of heavy drinking and drug using women (N=594) recruited for two on-going community based HIV prevention studies in St. Louis City was analyzed to evaluate this association using path analysis. The women were stratified into two groups: sex traders and non-sex traders. Sex traders were more likely than non-sex traders to report being forced to kiss or touch someone in a sexual way before age 15 (35% vs. 22%), being kissed or touched in a sexual way by others when they did not want to be (42% vs. 31%), and being forced to have sexual intercourse (30% vs. 21%). Sex traders were more likely than non-sex traders to use a weapon or threaten someone with a weapon (29% vs. 18%) and physically hurt others on purpose before age 15 (9% vs. 5%). Path analysis confirmed that childhood victimization had a significant and direct association with both adult cocaine dependence and sex trading. However, the association between childhood perpetration and adult sex trading was mediated by cocaine dependence. This analysis concludes that childhood victimization was the strongest predictor of cocaine dependence and sex trading in adulthood.
