Filter by:Medication adherence rates among youth living with HIV are inadequate to effectively manage the disease, and novel interventions grounded in basic behavioral sciences are needed. This multi-site phased (3 phases) study plans to translate basic cognitive neuroscience regarding prospective memory (PM) into a more potent adherence intervention for youth living with HIV (YLH). The phases are: Phase 1: To improve PM in basic laboratory tasks in YLH with and without substance abuse. -Hypothesis 1: Manipulations in three theory-based components of PM (strategic encoding, self-monitoring and cue salience) will improve PM within each participant. Phase 2: To conduct proof of concept studies of a text-delivered PM intervention for taking ART in YLH with suboptimal adherence. - Hypothesis 2: Using a multiple baseline across subjects design, adherence to antiretroviral therapy (ART) will improve following initiation of the PM adherence intervention and will be maintained for 6 weeks after tapering of the intervention. - Hypothesis 2a: Similar feasibility, tolerability, and adherence improvement trends will be seen in youth with and without substance problems. Phase 3: To conduct additional proof of concept studies, based on Phase 2 findings, of a text-delivered PM intervention for taking ART in YLH with suboptimal adherence. - Hypothesis 3: Using a multiple baseline across subjects design, adherence to ART will improve following initiation of the PM adherence intervention and will be maintained for 6 weeks after tapering of the intervention. - Hypothesis 3a: Similar feasibility, tolerability, and adherence improvement trends will be seen in youth.
The purpose of the proposed study is perform focus groups to identify and prioritize features of the SubAID application (APP). The SubAID APP is smartphone APP being created to support patients self-managing buprenorphine/naloxone (bup/nal) medication. Many people have difficulty in managing bup/nal in the prescribed manner. Not taking medicines in their prescribed manner can cause negative health outcomes. Focus group participants will be asked to elaborate on medication-taking patterns that work best for them, pitfalls associated with poor adherence and offer opinions upon what features/functions the SubAID APP should perform to be most helpful to them. The focus group is designed to remain open-ended and allow free discussion regarding each particular topic that the moderator will bring up.
The purpose of this study is to investigate effects of methylphenidate, modafinil, and 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy") on emotion-processing and cognitive performance using functional magnetic resonance imaging (fMRI) techniques. The primary hypothesis is that these psychostimulants differentially affect processing of emotional stimuli and potentially leading to alterations in social cognition and behavior.
INTRODUCTION. One of the main problems of the treatment of cocaine-dependent patients is the high rate of relapses occurs within the first months after detoxification. In the early withdrawal phase, patients suffer severe anxious depressive symptoms, known in the argot as crash, which occurs in parallel with an appetite overflowed by re-experiencing the effects of the substance, known as craving. Most of the times, these clinical symptoms act as negative reinforcement, which can be severe enough to induce a drug-relapse that greatly hampers the treatment. TYPE OF STUDY randomized, double-blind, placebo-experimental. GENERAL PURPOSE To determine the efficacy of mirtazapine for the treatment of cocaine dependence. SPECIFIC OBJECTIVES 1) To evaluate the efficacy in the treatment of craving in individuals with cocaine dependence disorder treated with mirtazapine during acute withdrawal phase. 2) Determine the efficacy of reducing anxious depressive symptomatology (Crash) associated with acute withdrawal in subjects with cocaine dependence disorder treated with mirtazapine. 3) Evaluate the maintenance of abstinence in patients with cocaine dependence disorder treated with mirtazapine. 4) Determine the efficacy of mirtazapine in the treatment of subjects dependent on cocaine comorbid with major depressive disorder. HYPOTHESIS For pharmacokinetics and pharmacodynamics mirtazapine contribute to the reduction in the intensity of withdrawal symptoms in cocaine dependent subjects by acting on the neurochemical circuitry involved in the reward-seeking behavior and has a prolonged effect anticraving. METHOD The attending physician outpatient identifies the Addiction Clinic of the National Institute of Psychiatry who meet the inclusion criteria and invite them to participate voluntarily. If patients accept, send them to the principal investigator for the start of the ratings. Demographics INSTRUMENTS, MINI structured interview, Anxiety and Depression Scale Beck Scale.
The purposes of this study is to examine the feasibility of implementing an internet-based treatment for insomnia among veterans with substance use disorders, some with co-morbid serious mental illness, and to develop potential methods to support and encourage veterans while they self-administer this treatment. Our hypotheses are that the implementation of an internet-based therapy will be feasible and that a method of support can be devised, and tested in the future.
The purpose of this study is to see if computer tasks that challenge the brain (cognitively stimulating tasks) can improve memory and other types of thinking in adolescents and young adults who are being treated for substance use problems. The study will compare the effects of different versions of the computer tasks.
The purpose of this study is to compare two models of substance abuse treatment in Vietnam, and how they each affect HIV care. In Vietnam, the current model for treating people with HIV who are also dependent on opioids is to refer them to methadone maintenance treatment centers. The new model the protocol will study is treatment of HIV and opioid dependence with buprenorphine/naloxone and counseling in the HIV clinic.
Substance abuse treatment in the criminal justice system can reduce drug use and related criminal behavior. Although drug and alcohol treatment are common mandates in criminal justice programs, only a minority of clients actually initiate treatment. This proposal will compare two intervention formats that target motivation to initiate and engage in treatment among a group of probationers who have drug or alcohol treatment conditions. Six hundred drug and alcohol offenders in two probation sites (Baltimore, MD and Dallas, TX) will be randomized to receive: 1) an in-person motivational interviewing session (MI), 2) a motivational computer program (MC), or 3) supervision intake and monitoring as usual (SAU). The MI condition will be structured along the lines of the "Check-Up" format which consists of an assessment and personalized feedback delivered in an MI style; the content of the MC condition will be drawn from previous literature on effective motivational computer programs. Both interventions will be delivered at the start of the probation process, with follow-up assessments at 2 and 6 months. Primary outcomes include engagement and participation in substance abuse treatment; secondary outcomes include drug and alcohol use, probation progress, criminal behavior, and HIV testing and care. This project will be the first to develop and test two interventions for encouraging criminal justice clients to follow through with treatment recommendations, with the goal of increasing treatment initiation, and reducing subsequent drug use and criminal behavior. It also contributes to ongoing partnerships with two large probation agencies—the Dallas County Supervision and Corrections Department and the Maryland Division of Parole and Probation.
Dropout represents one of the largest problems in substance abuse treatment. International and Nordic research show that only 20 - 40 % of substance abusers complete treatment as intended. At the same time, one of the most consistent factors of favourable post-treatment outcome is treatment completion. In spite of the serious and continuous challenge dropout represents the phenomena is not well understood and there is a need to explore more of the factors that influence dropout and how it can be counteracted. As also stated: "…effective methods for reducing the problem of dropouts from treatment is one more area in need of further research" (NOU 2003:4, s 77). For the general field of mental health one of the most important innovations involves providing therapists with patient feedback about their progress. The most well-established and widely researched feedback system is the Outcome Questionnaire (OQ-45.2). The system has been shown to improve treatment outcomes, including reduced treatment dropout and length of treatment, but the system is yet to be utilized with a substance abusing patient group. The aim of the present study is to examine the usefulness of OQ-45.2 with substance abusing patients.
The clinical trial portion of this study tests the hypothesis that contingency management-based incentives for primary care patients with substance use disorders to attend treatment services will increase treatment initiation and engagement. The investigators are investigating whether this approach that has been found effective in specialty treatment settings will work in the primary care context, in conjunction with screening.
