Filter by:Dependence on tobacco derived nicotine is a major public health problem. Substance users who complete training in mindfulness subjectively report increased patience and improved motor control over their impulses. Yet, no studies have tested this perceived benefit with behavioral measures of impulse control. The investigators are conducting a randomized controlled clinical trial, which compares Cognitive-Behavioral Therapy and Mindfulness Training for tobacco smokers, using behavioral measures to investigate the effects of mindfulness training on impulsivity and inhibitory control.
The proposed study uses a randomized controlled experimental design to evaluate the efficacy of a brief intervention using spiritual self schema (3S+) counseling to simultaneously target HIV health outcomes, and substance use among alcohol and/or drug dependent HIV positive older adults (age 50+), relative to an attention control condition. Participants will be randomly assigned to receive either: (1) 12 sessions of 3S+ counseling, adapted for the present study to target both non-injection drug use, drinking, and HIV health; or (2) 12 sessions of education about HIV health and the associated with alcohol and drug use that will serve as an attention-control.
The primary objective of the study is to test the incremental efficacy and outcomes of an aftercare program of Cognitive Behavioral Therapy combined with motivational therapy (CBT-MT) relative to treatment as usual (TAU) in improving depression, substance use, and healthcare outcomes in a population with drug dependence and comorbid major depressive disorder (MDD). The investigators expect that among drug-dependent patients with comorbid MDD, CBT-MT will yield better clinical outcomes relative to TAU in reducing depressive symptoms and substance use and improving healthcare outcomes during treatment. Secondary Objectives: 1. Test efficacy and outcomes of CBT-MT and TAU 2. Evaluate the differential effect of CBT-MT versus TAU on HIV-risk behavior of participants, 3. To evaluate the impact of cognitive functioning on treatment retention and outcomes, and 4. To explore additional psychosocial, demographic, and diagnostic factors (e.g., age, gender, education level, motivation for change, social support) that may be associated with treatment outcome and retention in this high need population.
This project focuses on the under-researched group of individuals who develop psychotic episodes of short duration (less than four weeks) while using substances. This includes individuals diagnosed with psychotic disorder not otherwise specified (PNOS) or substance-induced psychotic disorder (SIP) AND substance abuse or dependence. Very little is known about the most appropriate maintenance/relapse prevention management of these subjects. These individuals are not diagnosed with a primary psychosis because psychotic symptoms are too short-lived or non-specific, the onset of substance use precedes the onset of psychotic symptoms and the subject has not experienced sufficient psychotic symptoms in the absence of substance use. However, previous studies have shown that they are at high risk of recurrence of psychotic symptoms. Thus, this project will assess the efficacy of the second-generation antipsychotic aripiprazole for maintenance treatment of subjects who had a recent psychotic episode of short duration associated with substance use. The investigators will compare aripiprazole and placebo for preventing the recurrence of psychotic symptoms and decreasing substance use during a 6-month maintenance phase.
This study will develop and test a brief telephone-delivered motivational enhancement intervention for substance abusing military personnel who are not currently in treatment. The hypotheses being tested are that this intervention will prompt a willingness to participate voluntarily in a self-appraisal of substance abuse behavior and consequences, self-initiated change or enrollment in a treatment or self-help program, and cessation of abuse of alcohol or other drugs.
This novel compound is a new experimental treatment that may help people to stop compulsive overeating. Compulsive overeating or binge eating is one of the main reasons why people are overweight or obese. Recent research has shown that some kinds of overeating may be linked to a brain chemical called dopamine. There is some evidence that blocking the action of this chemical in animals can reduce food intake, particularly of foods that are high in fat and sugar. The purpose of this study is to find out if this compound (which blocks the effects of dopamine) has the same effect in overweight or obese people, as it does in animals.
The proposed study will evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of repeated oral doses of GSK618334 in healthy male and female volunteers.
Purpose: This is an outpatient, randomized, double-blinded, placebo-controlled study in which either varenicline (twice daily) or placebo will be administered over a 12 week study period to examine genetic influences on treatment response to varenicline for reduction of hazardous drinking.
This study will compare the effects of GSK598809 and placebo in alcohol dependent volunteers. A placebo is a pill with no drug in it (i.e. dummy drug) but it is made to look exactly like the real drug. Subjects will be given one dose of GSK598809 during one visit and placebo during the other visit. These dosing visits will be at least 1 week apart. The study is randomised, which means that a computer programme will decide by chance (like tossing a coin), the order in which subjects will receive GSK598809 or the placebo, or in other words, whether they will receive GSK598809 or placebo first. The study is blinded, which means the subjects will not know whether they are receiving study drug or placebo first and neither will the doctors at the institute. If necessary for reasons of safety, the study staff can find out exactly what the subject has received. The study will last for approximately 4 weeks but could be up to 6 weeks, depending on length of time between screening and dosing. From screening the subjects will be alcohol-abstinent, they may be put on medication for treatment of withdrawal symptoms and then will have at least 7 days without any medication before beginning the study medication. During the study the subjects will be inpatients at the Central Institute of Mental Health. All subjects will be required to fill out questionnaires, perform behavioural tasks and undergo MRI and functional MRI (fMRI) scans.
This study will investigate the possible effects of alcohol in combination with GSK598809 on the central nervous system in 20 healthy male and female volunteers, between 18 and 65 years of age. During 4 separate study periods subjects will receive the following treatment combinations: Alcohol + GSK598809, alcohol + placebo drug, placebo infusion + GSK598809, and placebo infusion + placebo drug. A placebo is a pill or liquid infusion which contains no drug or alcohol; it is a dummy version. Therefore it is administered in the same way that either the study drug or ethanol is depending on which placebo it is. All study drugs are administered in a random order and both the doctor and the participant are not aware of the treatment combination. However treatment combinations will be available at the end of the study or in case of an emergency. GSK598809 is administered orally and alcohol is administered per infusion. The duration of the infusion is 5 hours, during which approximately 75 grams of alcohol is infused, which is comparable to less than one bottle of wine.
