Filter by:The study will seek and recruit substance-using Black Men who have Sex with Men (MSM) in New York City for Human Immunodeficiency Virus (HIV) testing and will link and retain those who are HIV infected in HIV primary care. The STAR study has two primary objectives: to evaluate the feasibility and effectiveness of Respondent Driven Sampling (RDS) in the substance using Black MSM population for identifying individuals who are HIV infected and not in care; and to assess the relative effectiveness of patient navigation and financial incentives in linkage and retention to HIV care.
The key research question in this study is whether or not caffeine facilitates genital sexual arousal in women in the presence of an external erotic stimulus. Caffeine's impact on the human sexual response cycle has yet to be studied in the field, so the goal is to determine if this substance will have any impact on genital arousal well as potentially identify the mechanisms underlying its ability to do so. Considering that this will be a single blind study, a key goal of the project is to determine how participant expectations regarding what they ingest will impact their subjective sexual arousal. At present, we hypothesize that, as caffeine's stimulant properties increase a human's heart rate and blood pressure, caffeine intake will facilitate genital arousal.
Methamphetamine abuse has a strong and consistent epidemiologic association with high-risk sexual behavior and both prevalent and incident HIV in men who have sex with men (MSM), and some authorities have advocated methamphetamine treatment as an HIV prevention strategy. However, methamphetamine interventions have not been evaluated in controlled trials, nor have they been implemented and assessed outside of substance abuse treatment programs. This application proposes preliminary investigations to adapt a methamphetamine treatment intervention previously associated with decreased sexual-risk taking among MSM for use as an early intervention among MSM in Seattle, Washington. Sixty methamphetamine-using MSM will be enrolled in a randomized controlled trial of contingency management (CM) versus no intervention. CM participants will have their urine tested for methamphetamine 3 times weekly for 12 weeks, and will receive vouchers of escalating value when their urines test negative; vouchers will be withheld when participants' urines test positive for methamphetamine or participants miss urine testing visits. All participants will undergo urine methamphetamine testing and audio-computer assisted self-interviews on sexual behavior and substance use at baseline and at 6 week intervals for 6 months. Participants will be tested for HIV, syphilis, rectal gonorrhea and chlamydial infection, and pharyngeal gonorrhea at baseline and at 3 and 6 month follow-up. The study will determine how often MSM will initiate and complete the early intervention, and will longitudinally measure unsafe sexual behaviors among intervention and control participants. Study results will determine the feasibility of instituting and studying CM as an early intervention; define whether the intervention is sufficiently promising to justify a larger, definitive randomized controlled trial; and will provide estimates for defining the number of participants such a trial would require.
This research is studying behaviors that young people engage in that may place them at risk for contracting a sexually transmitted disease like HIV/AIDS, and what kind of educational program works best to reduce these risky behaviors.
This research is examining how genetic and brain factors play a role in adolescents' health risk behavior as well as studying behaviors that young people engage in that may place them at risk for contracting a sexually transmitted disease like HIV/AIDS, and what kind of educational program works best to reduce these risky behaviors.
The investigators propose to develop and evaluate a computer-based intervention using cell phones to enhance adherence to antiretroviral treatment (ART) and support of HIV transmission risk-reduction among adult HIV-positive patients in Peru.
The Community Youth Development Study is an experimental test of the Communities That Care (CTC) prevention planning system. It has been designed to find out if communities that were trained to use the CTC system improved public health by reducing rates of adolescent drug use, delinquency, violence, and risky sexual behavior when compared to communities that did not use this approach. The primary purpose of the current continuation study is to investigate whether CTC has long-term effects on substance use, antisocial behavior, and violence, as well as secondary effects on educational attainment, mental health, and sexual risk behavior in young adults at ages 26 and 28. The continuation study also examines (a) how the interaction of social, normative, and legal marijuana contexts creates variation in the permissiveness of individuals' marijuana environments from late childhood to young adulthood and (b) whether, when, and for whom permissive marijuana environments increase marijuana and ATOD use and misuse from age 11 to 28 and interfere with the adoption of adult roles.
The focus of this study will be to test the Familias Unidas Intervention program among Hispanic 8th graders in the Miami-Dade County Public School System. This study will contribute to the advancement of knowledge in both the scientific community and the Hispanic population in Miami-Dade County. It will shed light on whether and to what extent Familias Unidas is effective in preventing drug use and unsafe sexual behavior in Hispanic adolescents. To the scientific community, the investigators will disseminate our findings via peer-reviewed publications and presentations at scientific meetings. The design for the proposed study is a randomized controlled trial. This design is considered the "gold standard" design when evaluating the efficacy of two (or more) treatment conditions. Participants for this study will be 744 Hispanic 8th grade adolescents and their parents recruited from 24 randomly selected middle schools in Miami Dade County that meet the school inclusion/exclusion criteria. A total of 12 schools (for a total of 372 Hispanic adolescents and their parents) will be randomized to Familias Unidas and a total of 12 schools (for a total of 372 Hispanic adolescents and their parents) will be randomized to the Community Practice.
This application is a competing continuation of a grant in which we developed and pilot tested a computerized Therapeutic Workplace designed to train and employ adults as data entry operators. A randomized trial is planned over 5 years to investigate the Therapeutic Workplace business as a maintenance intervention to sustain long-term abstinence and employment. Welfare recipients in methadone treatment, actively using cocaine, and at risk for contracting or spreading HIV infection will participate in an initial Therapeutic Workplace training phase. Participants who become abstinent and skilled will be randomly assigned to an Abstinence & Employment, or an Employment Only group. Participants in the Abstinence & Employment group will be employed for one year in a Therapeutic Workplace business and will have to provide drug-free urine samples to work and earn salary. Employment Only participants will be offered employment for one year, but these participants will not have to provide drug-free urine samples to work. This study will provide a rigorous evaluation of the efficacy of the Therapeutic Workplace business as a long-term treatment of cocaine addiction and unemployment; determine the benefits of requiring daily evidence of abstinence to work; and provide information on the extent to which a Therapeutic Workplace business can become self-sustaining. This research could provide firm scientific foundation for the dissemination of Therapeutic Workplace businesses in the long-term treatment of cocaine addiction and unemployment. The main hypothesis being tested is that cocaine abstinence will be reliably maintained during the yearlong intervention evaluation period only in the group exposed to the explicit abstinence maintenance intervention. We expect that cocaine abstinence in the Abstinence and Employment group will be significantly greater than cocaine abstinence in the Employment Only group.
The MEMA kwa Vijana Project is a community randomised trial which aims to assess the impact of a targeted intervention on adolescent sexual and reproductive health in Mwanza Region, Tanzania. The intervention aims to reduce HIV, STD and unwanted pregnancy amongst adolescents by improving reproductive health knowledge and by teaching skills to promote sexual behaviour change, and comprises community mobilisation, skills-based education in primary schools, and youth friendly health services. The evaluation includes a detailed process evaluation, and evaluation of the impact in a cohort of approx. 10,000 adolescents who will be followed for 3 years.
