Filter by:This investigation seeks to better define the genetic basis for vulnerability to substance abuse.
Background: - Research has shown that several human genes have been associated with vulnerability to substance abuse and dependence. However, little is known about how people with these genetic tendencies react to drugs in controlled settings. - Methylphenidate, also known as Ritalin, is commonly prescribed for a number of conditions, including attention deficit disorder. Because methylphenidate is widely used in studies of brain chemistry and behavior and has relatively low risks associated with it use, researchers are interested in seeing how it affects the thinking processes of people with apparent genetic vulnerability to drug abuse. Objectives: - To evaluate whether individuals with apparent genetic vulnerability to drug abuse react differently to methylphenidate than people who do not have this vulnerability. Eligibility: - Individuals at least 18 years of age or older who have participated in the NIDA protocol Allelic Linkage in Substance Abuse. Design: - Participants will be asked to avoid using a number of over-the-counter medications, including antihistamines, cough medicines, and nasal decongestants, for 24 hours before the study day. Participants will also be asked to avoid consuming caffeinated beverages, nicotine or tobacco products, or alcohol on the morning of the day of the study, and will provide a urine sample at the start of the study to be tested for chemicals that may interfere with the study. - Because of the nature of the study drug, participants will not be allowed to drive to the clinical center on the day of the study. (Return transportation will be arranged.) - At the start of the study, participants will take two tablets (each 1 hour apart), and will not be told whether the tablets are the study drug or a placebo. - Participants will give regular answers to questions about mood and thinking processes on a computer for approximately 5 hours. Blood samples will be taken during this part of the study.
This research is being done to evaluate if NRP 104 is a safe drug. The other purpose is to learn if NRP104, when injected into a vein, produces a high and any other effects like amphetamine and other stimulant drugs that are abused. This information will give some indication if NRP104 can be abused. Healthy people, between the ages of 18 and 55 with histories of substance abuse that include stimulant drugs, may join. Amphetamines are drugs that are used most often to treat attention deficit hyperactivity disorder (ADHD) in children, to treat narcolepsy (excessive sleepiness) and for weight loss.
This study will determine the efficacy of a parent-involved intervention in preventing problem behavior in middle school girls who are currently in foster care.
The investigators are proposing a study of treatment adherence in co-occurring psychiatric and drug use disorders (COD). The proposed study uses a 3-cell/condition design, within which 75 adult outpatients with co-occurring psychiatric disorders and drug abuse/dependence (CODDA) will be randomly assigned to one of the following brief, 8-week, manual-guided interventions following a 2-week "Assessment Only" baseline period: 1. Adherence Feedback (AF); this condition will entail weekly, 20-25 minute sessions of AF, which is a procedure that represents a technological advancement developed by Cramer et al. (1989, 1995, and 1999) and is based on the use of adherence data from the microelectronic monitor in Medication Event Monitoring System (MEMS) caps, 2. AF + Contingency Management (AF + CM); in this condition, participants will receive AF, as described above, PLUS contingency management. CM is based on the behavioral learning theory, which suggests that the occurrence of a behavior is increased as a function of the rate at which it is positively reinforced or rewarded, or 3. AF + Motivational Enhancement Therapy (AF + MET); in this condition, patients will receive AF, as described above, PLUS motivational enhancement therapy. MET is based on the idea that an effective way to motivate behavior change is to assist patients in clarifying their ambivalence (i.e., reasons for and against changing/adhering), utilizing a series of strategies based on client-centered psychotherapy, self-efficacy theory, and social psychology. The study will allow the evaluation of three hypotheses: 1. AF + MET is superior to AF + CM, 2. AF + MET is superior to AF alone, and 3. AF + CM is superior to AF alone. Primary outcome measures are: 1. rates of adherence to medication (i.e., selective serotonin reuptake inhibitors or SSRIs), as measured by MEMS caps and self-report, 2. rates of counseling attendance, and 3. reductions in illicit drug use, including achievement of abstinence, as assessed by twice-weekly urine toxicology tests and self-report. Secondary outcomes include reductions in psychiatric symptomatology and rates of re-hospitalization. The investigators will also evaluate the relationship between adherence and primary and secondary outcomes.
The purpose of this study was to collect pilot data on whether quetiapine may be effective in the reduction of cocaine use and cravings in cocaine dependent individuals.
This study aims to treat young people with an adjunctive integrated cognitive behavioral therapy (CBT) intervention and to examine the acceptability of this treatment approach within this population. The study will also include a pilot placebo-controlled trial of sertraline for those young people who fail to or only partially respond to the CBT intervention, so as to determine whether adjunctive anti-depressant treatment improves clinical response in this population.
The purpose of this study was to develop a gender-specific 12-session, manual-based relapse prevention group for women with substance use disorders (SUDs).

Pilot trial of computer-based motivational intervention. Hypothesis: The brief computer-delivered intervention would result in higher motivation to change at follow-up.
