Active clinical trials for "Substance-Related Disorders"

The purpose of this Stage II clinical trial is to test the efficacy of a culturally sensitive, cognitive-behavioral intervention to reduce sexual risk behavior among minority adolescents for prevention of sexually transmitted infection (STI/HIV), unintended pregnancy and abuse by changing high-risk sexual behaviors, decreasing substance use and encouraging contraceptive use. Its primary goal is to expand risk-reduction interventions created in previous studies to further increase intervention efficacy for this particularly vulnerable, high-risk group. An adolescent intervention has been created and pilot tested in developmental studies. Results indicated reductions in substance use, risk behaviors, unintended pregnancy, STI and abuse without reports of adverse outcomes. Specific aims of the current study include: 1) To obtain a more in-depth understanding of configurations of psychosocial and situational factors associated with high-risk sexual behavior, substance use, STI/HIV and contraceptive use among abused minority adolescent women with STI; 2) To implement a controlled randomized trial of a cognitive behavioral risk-reduction intervention consisting of 2 small group sessions, 2 individual counseling and 3 support groups for this group; 3) To evaluate the effects of the adolescent intervention model versus enhanced counseling for this group on AIDS Risk Reduction Model (ARRM)-related constructs, high-risk sexual behavior, substance use, abuse recurrence, contraceptive use, unintended pregnancy and STI/HIV at 6 and 12 months follow-up. Participants will include a convenience sample of 600 Mexican-and African American adolescent women, aged 14-18 years with a history of sexual or physical abuse and current STI.

The goal of this project is to evaluate the effectiveness of a family-based tobacco use prevention intervention directed at immigrant Latino parents of middle school aged youth as delivered in partnership with seven community organizations. The primary outcomes of the study are youth susceptibility to tobacco use, and changes in parenting practices among the parents of the youth. The planning, initiation, and delivery of the intervention will occur in collaboration with community organizations that have identified this project as important to the families they serve. Though the collaboratively designed training curriculum has been successfully tested and a study design for the current project established, a substantive development period for this project will allow the research team and collaborating organizations to consider key aspects of design and delivery.

The goals of this study are to develop a middle school substance use prevention curriculum for underserved rural youth and evaluate its efficacy compared to the existing, multicultural curriculum. In addition, we are studying how the curricula get taught by the teachers. Hypothesis 1: When compared to students in the control condition, students in the treatment conditions will report less substance use, more conservative norms, less positive expectations about substance use outcomes, and better life and communication skills. Hypothesis 2: When compared to students in the control condition, students in the researcher adaptation condition will report less substance use, more conservative norms, less positive expectations, and better life and communication skills. Hypothesis 3: When compared to students in the control condition, students in the teacher adaptation condition will report less substance use, more conservative norms, less positive expectations, and better life and communication skills. Hypothesis 4: Researcher adaptation will have a greater impact on substance use, norms, and expectations than teacher adaptation.

The purpose of this study was to determine whether a media literacy education program taught be teacher to late elementary school students (grades 3-5) positively affected students' critical thinking skills and substance use-related health outcomes.

Background: - Little research has been done on how different components of cannabis (marijuana) appear in oral fluid (i.e., saliva) after smoking. Cannabinoids have been well studied in whole blood, plasma, and urine after cannabis use, but less is known about how cannabinoids appear in oral fluid after controlled drug administration and how long these biomarkers last after use. In addition, the issue of stability of cannabinoids and their glucuronide metabolites is a controversial topic that is poorly understood. These data are critical to the interpretation of cannabinoid test results. Objectives: To collect whole blood, plasma, urine, and oral fluid specimens after smoking cannabis, to characterize the disposition and pharmacokinetics of cannabinoids in multiple biological matrices and to provide scientifically reliable data on the stability of cannabinoids and metabolites. To test basic brain function and thinking processes after smoking cannabis. Eligibility: - Healthy volunteers between 18 and 45 years of age who use cannabis (an average of at least twice per month in the 3 months before the study.) Design: Participants may complete the single study session as outpatients, or they may spend the night prior to and/or following drug administration at the residential research unit in Baltimore, MD. Participants must provide a negative urine drug screen if they have not spent the evening prior to testing at the research unit. Participants will provide whole blood, plasma, oral fluid, and urine samples, and will complete several tests of thinking and brain function at the start of the study. Participants will smoke one standardized cannabis cigarette. Blood and oral fluid samples will be collected, and participants will repeat the tests of thinking and brain function multiple times after smoking. Six hours after smoking the cigarette, participants must pass a neuromotor exam (testing balance and coordination) before they can be discharged from the study. Participants may be asked to stay overnight at the clinical center if there are concerns for their safety because of intoxication.

The primary aim of this study is to test a brief 4-session risk reduction intervention, based on Motivational Enhancement Therapy (MET) to reduce the co-occurrence of club drug use and sexual risk taking behaviors among non-treatment seeking young men who have sex with men (YMSM) in NYC.

The purpose of this study is to determine the effect of GSK598809 as compared to placebo in preventing recently-quit smokers from going back to smoking.

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 study evaluates a contingency management program that rewards homeless, non-treatment-seeking substance abusing men who have sex with men (MSM) for abstaining from drugs and for performing prosocial behaviors. If this program motivates these individuals to increase prosocial and healthy behaviors and decrease drug/alcohol use, established prevention programs may modify their approaches to include contingency management, and use it to address the staggering public health problems homeless substance-abusing MSMs face on a daily basis.

This study will examine safer sex skills building (SSB), a targeted behavioral HIV prevention and risk reduction group intervention in two samples of pregnant drug abusing women.
