This paper investigates injecting, shared use of needles/syringes and sexual risk behaviours at intake to treatment and at one-year follow-up among 753 drug users recruited to the National Treatment Outcome Research Study (NTORS). Injecting, sharing and having unprotected sex were substantially reduced among clients admitted to methadone programmes and among those admitted to residential treatments. The overall levels of risk fell after treatment, and the majority of those who were engaged in high risk behaviours at intake had stopped at follow-up. The results also show the variability of individual outcomes. A minority persisted with their risk behaviour, and others who were not at risk at intake who had started to engage in risky behaviours at follow-up. The behaviour of these clients creates a focal point for risk as well as being a threat to public health. Several social and psychological factors were predictive of health risk behaviours. These included frequency and duration of heroin use, polydrug use, alcohol use, gender, ethnicity, having a drug-using partner, anxiety and depression. The results indicate the important role that can be played by treatment services in helping to reduce the risk of blood-borne infections. We suggest that risk reduction interventions are an important and effective component of treatment programmes. This study examined the effectiveness of a combined counseling and case management behavioral intervention, using motivational interviewing strategies, in engaging Hispanic injection drug users in treatment and reducing drug use and injection-related HIV risk behaviors. Follow up data are presented on 440 (79.0%) of 557 randomized participants, 6 months after the initial interview. Subjects in the experimental arm were significantly less likely to continue drug injection independent of entering drug treatment, and were also more likely to enter drug treatment. Subjects in both arms who entered drug treatment were less likely to continue drug injection. Among subjects who continued drug injection, those in the experimental arm were significantly less likely to share needles. Confirming the outcomes of this study in other Hispanic sites and populations could be a critical step towards reducing factors that contribute to the self-sustaining HIV/AIDS epidemic in Puerto Rico and communities in the U.S. mainland. Although most women infected with HIV are intravenous drug users, some contact the virus through sexual contact with IV drug users. To reach at-risk women, public health officials must develop a range of prevention strategies. One approach, skills training, holds promise as a means of altering risk-related sexual behavior. In this study, 91 women methadone patients were pretested and randomly assigned to an information-only control control group or a skills-building intervention group. Skills-building intervention consisted of five sessions of small groups in which participants identified their own high risk sexual behaviors, discussed their negative associations with condoms, and practiced skills which involved asking partners to use condoms. Compared with members of the control group, respondents in the intervention group reported that they initiated discussion of sexual issues with their partners more frequently, felt more comfortable talking with them about safer sex, and reported using and carrying condoms more frequently. The high rates of attendance and program retention by skills-building participants suggest that such groups may be supportive and useful in the design of risk reduction and drug abuse treatment programs. The modest outcomes of this study underscore the difficulty of altering risk behavior but also serve as a basis for future AIDS prevention studies. Pregnant injecting drug users were randomly assigned to: (i) individually receive a six-session cognitive-behavioural intervention in addition to their usual methadone maintenance treatment (intervention condition (I) (n = 40)); or (ii) their usual methadone maintenance treatment only (control condition (C) (n = 40)). There was no change in drug use per se in either group after the intervention. However, at 9-month follow-up the I group had significantly reduced some HIV risk-taking behaviours (in particular injecting risk behaviours). The I group reduced the needle risk associated both with "typical" use (drug use in the month before interview) and "binge" use (drug use in the month nominated as the heaviest month of drug use in the previous 6 months). The intervention had no effect on sexual risk behaviours. The finding of reduced injecting risk behaviour following the six-session intervention suggests that such an intervention may be of benefit for individuals persisting with injecting risk behaviours despite methadone maintenance treatment and the availability of sterile injection equipment. To evaluate the effectiveness of relapse prevention (RP) and brief intervention (BI) in reducing HIV risk-taking behaviours among injecting drug users (IDU) enrolled in methadone programmes. The hypotheses tested were: (1) that a six-session RP programme would be more effective in reducing HIV risk-taking behaviours than a one-session BI and a non-intervention control condition (C); and (2) that BI would be more effective in reducing HIV risk-taking behaviours than C.
                Clients of methadone programmes were randomly assigned to either RP, BI, or C. Follow-up occurred 6 months after pre-intervention assessment and was conducted by independent research assistants who were not aware of subjects' group allocations.
                Confidential assessment interviews and interventions generally took place at the methadone unit treating the subject.
                Ninety-five IDU enrolled in methadone programmes. Study entry criteria were: injection of any drug in the 6 months before the day of pre-intervention assessment; literacy in English; agreement to HIV-antibody testing for research purposes; and no known diagnosis of a serious mental illness. Eighty subjects were contacted successfully for a 6-month follow-up.
                The RP intervention was a six-session programme. Each 60-90 min session was conducted individually. The BI was a one-session motivational interview lasting 60-90 min, accompanied by a self-help booklet.
                All subjects were administered the Drug Use Scale and HIV Risk-Taking Behaviour Scale of the Opiate Treatment Index and consented to the collection of a capillary blood sample for HIV-antibody testing at pre-intervention assessment and follow-up. At follow-up, the Highest HIV Risk-Taking Behaviour Scale, collateral reports from subjects' sexual partners pertaining to the previous month and urinalysis results for the month before follow-up were collected.
                Compliance with interventions was good. Correspondence of self-reports with urinalysis and collateral reports was satisfactory. There were no significant differences between groups in risk-taking behaviours during the month before follow-up. However, there was evidence of a lower rate of needle-risk behaviour (sharing and cleaning) during the heaviest risk-taking month since pre-intervention assessment in the group given RP. There were no indications that BI was of greater benefit than the usual methadone treatment and neither intervention appeared to reduce sexual risk behaviour.
                The results are cautiously interpreted as showing that individual RP programmes decrease the level of needle-risk behaviour during relapse episodes, but further research is required to replicate this finding. This report examines the extent to which an educational component enhanced the efficacy of a community outreach program in reducing HIV transmission behaviors among injecting drug users (IDUs). The experimental enhancement comprised three group educational sessions where detailed information on HIV risk and protective behaviors was conveyed, protective behaviors were shown and practiced, and a problem solving perspective guided discussion of serostatus results. Substantial risk reduction in behaviors were prospectively measured. However, IDUs assigned on a random basis to the enhanced intervention showed no significant differences in levels of risk reduction when compared to those assigned to the standard-only intervention. The chronic and intensive use of injected drugs among the IDUs studied and their high level of HIV infection suggest the need of interventions geared to maximize the utilization of health care services and enhance the supportive functions of familial and social networks of IDUs. Methadone maintenance programs (MMP) have the potential to play an important role in reducing HIV risk, given the appropriate type and level of ancillary treatments. In this study, we investigated the efficacy of a 12-session harm reduction group intervention for injection drug users, based upon the Information-Motivation-Behavioral skills model of behavior change, that focused on reducing both drug and sex risk. Two hundred and twenty patients entering an MMP were randomized to receive either standard care (SC)-2 hours of counseling per month and a single-session risk reduction intervention-or SC plus the harm reduction group (HRG). Results showed that during treatment, patients receiving HRG were more likely to be abstinent from cocaine and to report fewer unsafe sexual practices. Post-treatment, HRG patients scored higher on a sexual risk quiz and reported increased self-efficacy in high risk sexual situations. Enhancing methadone maintenance with a weekly harm reduction group treatment was somewhat more expensive but can bring about positive changes in behaviors and attitudes that are associated with the transmission of HIV. This study examined and compared the effectiveness of two counseling interventions designed to reduce the HIV drug and sexual risk behaviors of 684 out-of-treatment drug users recruited from South Philadelphia, PA. All study participants received a standard intervention and one half were randomly assigned to also receive the enhanced intervention. The standard intervention provided HIV risk reduction education, HIV testing with pretest and posttest counseling, and training in condom use and needle cleaning. The enhanced intervention provided additional information on STD risk reduction. Both interventions were effective in influencing behavior change between baseline and 6-month follow-up. A higher proportion of persons reduced their drug risk behaviors compared to their sexual risk behaviors. As sexual risk behaviors are more resistant to change, there is a need for tailored interventions that target out-of-treatment drug users. Cocaine use is associated with injecting and sexual HIV risk behaviors. This study was a randomized controlled trial of behavioral interventions for cocaine dependence and HIV risk behaviors among dually (cocaine and heroin) dependent outpatients. Methadone maintenance was augmented with cognitive-behavioral therapy (CBT), contingency management (CM), both (CBT+CM), or neither. The study sample (n=81) was 52% female, 70% African American, and 37.9+/-7.0 years old. Proportions reporting HIV risk behaviors at intake were: 96.3% (78/81) injection drug use, 56.8% (46/81) sharing needles, 30.9% (25/81) unprotected sex, 28.4% (23/81) trading sex for money or drugs. Proportions who no longer reported behaviors at study exit were: 51.3% (40/78) injection drug use, 91.3% (42/46) sharing needles, 88% (22/25) unprotected sex, 91.3% (21/23) trading sex for money or drugs. Participants receiving CBT+CM were more likely to report cessation of unprotected sex relative to control (OR=5.44, 95% CI 1.14-26.0, p=0.034) but this effect was no longer significant after adjusting for drug-negative urines. These results suggest broad beneficial effects of methadone maintenance augmented with behavioral interventions for reducing HIV risk behaviors.
There is limited support for the widespread use of formal multi-session psychosocial interventions for reducing injection and sexual risk behaviour. Brief standard education interventions appear to be a more cost-effective option. Further research is required to assess if there are particular groups of drug users more likely to respond to such interventions.
