Filter by:The study purpose is to examine whether there are structural or functional differences in the brains of individuals who use cocaine or amphetamines as opposed to control participants who have never used cocaine or amphetamines. More specifically, it will allow the investigator to see how the brain changes once people get sober and how those changes relate to successful recovery. This study will allow the investigator to examine the interaction between cocaine/amphetamines and impulsivity (meaning to act on impulse rather than thought). Results from this study will inform new biologically-based interventions to compliment existing treatment programs, in the hope of leading the field in a new direction.
The purpose of the study is to determine the safety and efficacy of an integrated treatment for substance abuse and posttraumatic stress disorder for young adults. The integrated treatment includes two established psychosocial treatments for substance abuse (Contingency Management) and posttraumatic stress disorder (Prolonged Exposure therapy).
The Sponsor is doing a research study to assess the effects of a smartphone program designed to help users smoke less and eventually quit. When participants join, their involvement in the core study will last 8 weeks. After 8 weeks, they will have the option to continue using the program to guide their quit journey or participate in follow-up research.
To determine the effect of an integrated care protocol on antiviral treatment and sustained virologic response (SVR) rates following initiation of direct acting antiviral therapies (DAA) treatments in 2011.
Despite conscious intentions to remain abstinent, persons with substance use disorders often find that negative emotions and environmental cues automatically "trigger" drinking and other substance use. This study aims to test whether activating the baroreflex mechanism can be used "in the moment" to help resist drinking triggers. It consists of 3 phases (Recruitment, Intervention, Follow-up). Stage 1: Trained research staff conduct a comprehensive clinical interview and questionnaires to assess participant's mood, substance use, and triggers. Participants are paired with a Primary Research Clinician (PRC) who will work with them during the intervention. Stage 2: Approximately 4 weeks after intake into the Center for Great Expectations Intensive Outpatient program, an 8-week intervention begins. Pre-and post-intervention laboratory sessions occur at Cardiac Neuroscience Laboratory, Center of Alcohol Studies, Piscataway, NJ. Some participants take part in pre- and post-intervention neuroimaging sessions (Rutgers University Brain Imaging Center, Newark, NJ). Participants are randomized into an active intervention or control group after the pre-intervention lab session. They are given an iPhone and trained to use a paced breathing app that is pre-loaded onto the phone. Participants in both groups use their app any time they anticipate or experience a trigger to drink or use drugs. Participants are compensated for their use of the app and the time for participation. To ensure that participants are correctly performing the paced breathing task, their PRC visit with them weekly to provide coaching sessions using a computer-based biofeedback program. During the 4th week, ECG and respiration data are collected. Participants also complete questionnaires about mood and triggers, and provide feedback on the usefulness of the app. During the lab sessions, participants complete a series of questionnaires and ECG, blood pressure and respiration are collected during four 5-minute tasks (resting baseline, non-resonance breathing, resonance breathing, and visual processing/attention). During the neuroimaging sessions, participants are placed in the scanner for structural scans and four 5-minute tasks (as tasks as previously noted); ECG and blood pressure are recorded. Stage 3: Participants are re-contacted 1 and 3 months after the intervention to complete questionnaires about their quality of life across multiple domains and the usefulness of the app.
In this study, the investigators seek to evaluate the effects of cannabidiol (CBD) on cocaine craving and relapse. Cocaine addiction is characterized by compulsive substance use and repetitive urges to consume the drug even after a sustained period of abstinence. While substance use remains the most obvious direct outcome of addiction, there is a growing interest in other core symptoms of this disorder. Craving has become a subject of great interest as it is a reliable intermediate phenotype of cocaine relapse and a distressing symptom of addiction associated with suffering. Indeed, even after a period of abstinence, cocaine-dependent individuals remain vulnerable to stress and other craving-inducing stimuli, which, in turn, lead to intense physiological responses and various negative feelings such as anger and sadness. Real-time daily monitoring of craving and drug use has shown that craving predicts cocaine relapse among cocaine-dependent individuals. In sum, working toward improving the treatment of craving could not only help prevent relapse, but also reduce patient distress on emotional, cognitive, and physiological levels. In the past decades, significant scientific efforts have been deployed toward the development of innovative strategies to beat cocaine addiction, but with partial success thus far. Psychosocial approaches have been widely used to help cocaine-dependent patients achieve better outcomes after drug cessation, but literature indicates that these strategies alone are at times insufficient to induce significant behavioural changes or a reduction in rates of drug consumption. Unlike other types of addiction, such as opioid and alcohol, no pharmacological treatment has yet been found to be truly effective in relieving cocaine-cessation symptoms like craving and anxiety or to prevent relapse. CBD is a natural cannabinoid with a favourable tolerability profile and discrete neurobiological actions that are linked to neural circuits closely involved in addiction disorders. Addiction to cocaine is characterized by alternating phases of intoxication and short abstinence, followed by recurrent drug-craving episodes which result in distress and relapse. Our hypothesis is that CBD a cannabinoid known for its broad spectrum properties is an interesting pharmacological contender to decrease cocaine craving and treat cocaine addiction. Previous studies conducted in animals and humans confirm that CBD is a very safe and tolerable medication.
Specific Aims: This study aims to assess the acceptability of asynchronous telepsychiatry (ATP) and synchronous (STP) in rural Skilled Nursing Facility (SNF) population, in a 12-month randomized controlled trial. ATP relies on video recording of a psychiatric interview, where the video is later reviewed by a psychiatrist to make a psychiatric diagnosis and treatment recommendation to the primary treatment team. STP is real-time, face-to-face psychiatric assessment using video conferencing to come up with a psychiatric recommendation. People residing in SNFs generally rely on primary and consultant physicians to visit them and rarely have outpatient psychiatrist follow-up. SNFs offer more services than what is available to primary care office, and include 24- hours skilled nursing services, physical therapy, nutritional consultation, occupational therapy, social services, wound care, and psychiatric consultation when available. SNF residents are unable to live independently due to their multiple medical comorbidities and are therefore more medically ill than patients who are typically seen in primary care settings. The present study aims to demonstrate feasibility and to collect pilot data in SNFs. This study is funded by the UC Davis Behavior Health Center of Excellence grant via the California Mental Health Services Act (Prop 63). In a larger, future study, the investigators intend to demonstrate that ATP will be no different than STP in clinical outcomes but will be more accessible and cost effective.
Innovative approaches are needed to optimize the benefits of treatment as prevention (TasP) among HIV+ substance users, who experience profound health disparities that amplify onward transmission risk. This project will systematically develop, refine and conduct an open pilot to assess the feasibility and acceptability of a two-phase emotion regulation intervention that targets emotional barriers to HIV-related self-care among individuals who endorse active substance use. Emotional barriers such as shame and internalized stigma have been identified as barriers to optimal HIV care among individuals struggling with HIV and substance use. To effectively implement TasP, strategies for addressing these barriers are needed. Utilizing transdiagnostic approaches (e.g., positive affect-focused emotional regulation, mindfulness and self-compassion) investigators will develop, refine and pilot a two-phase emotional regulation intervention that requires only 5 face-to-face hours and can ultimately be implemented by a case-management-level staff person or trained peer educator. The first phase of the intervention will be a multicomponent in-person intervention targeting emotional, cognitive and behavioral barriers to HIV self-care behaviors among HIV+ substance users. The second phase of the intervention will extend the intervention benefits by sending personalized positive self-reappraisal text messages in response to text message queries about participants' mood. This phase will use an innovative personalized bi-directional platform, which will leverage an existing text message delivery system. This project will be instrumental in developing a relatively low-resource intervention strategy to address unmet emotional barriers to optimal HIV-care among individuals who are actively using substances. This work will provide the necessary pilot data for a subsequent grant submission to assess the preliminary efficacy of the intervention. The resulting intervention has the potential to address emotional barriers to self-care along the HIV care cascade: including retention in care, antiretroviral treatment adherence and persistence, and ultimately viral suppression.
The purpose of this study is to determine whether Moral Reconation Therapy (MRT) is effective for reducing risk of criminal recidivism and improving other health-related outcomes (substance use, mental health, housing, and employment problems) among justice-involved Veterans entering residential mental health treatment programs in the Department of Veterans Affairs (VA).
Aim: The purpose of the study is to examine the effects of medication, placebo and expectation on objective and self-rated performance of ADHD core signs during the Quantified Behavior Test in patients with untreated ADHD and substance Use Disorders. Subjects: Participants are 40 consecutive patients remitted to a neuropsychiatric investigation at the Dependence Clinic Västmanland, Västerås, Sweden. Method: The study is a double-blind, randomized, placebo-controlled, cross-over study. The study is taken place during four hours on two investigating days, separated by a 4 days wash-out period. All patients participate on two occasions: In one session they receive the Methylphenidate (MPH) condition, and in the other session they receive the placebo condition. MPH and placebo conditions are counterbalanced across subjects such that half of the participants receive MPH first, and half receive placebo first. Neither the patient nor the research assistant is aware when the participant receive the MPH condition or the placebo condition. On each investigating day the participant accomplish Questionnaires (Visual Analogical Scales) concerning; (a) expectation, (b) self-rated performance, (c) exhausting exercise, (d) perceived help from the pill and (e) self-rated symptoms. In addition the participant completed A Quick Test of Cognitive Speed (AQT) and two separate Quantified Behavior Test Plus (QbTest) without medication vs MPH/Placebo. QbTest aims to provide objective information regarding core-symptoms of ADHD; hyperactivity on the basis of motor-activity measured with the camera, and inattention and impulsivity on basis of the CPT-test.
