Active clinical trials for "Behavior, Addictive"

The purpose of this research program is to understand how a biomarker called the "nicotine metabolite ratio" (also referred to as NMR) may influence a smoker's ability to quit smoking.

Contingency Management (CM) is highly effective in promoting recovery from substance use disorders, but benefits tend to attenuate over time when CM is discontinued. Identifying modifications of CM delivery that can extend its benefits is an important goal. The goal of this study is to evaluate the use of reinforcements to increase physical activity, specifically walking. The study provides a standard CM intervention to promote walking for three weeks. After three weeks, a progressively increasing variable interval schedule of reinforcement will be evaluated for increasing the durability of effects of the initial CM intervention. We hypothesize that Variable Interval Prize Contingency Management will result in greater adherence to a walking goal of 10,000 steps per day at Week 15 and Week 24 compared to the Control Condition.

The purpose of this study is to evaluate the effects of IV dynorphin in humans during acute heroin abstinence, in order to determine that dynorphin suppresses acute opiate withdrawal, reduces opiate craving, and is safe at doses required to produce the above effects.

This is a pilot study to test the feasibility of a recruitment strategy and study protocol to examine the effects of a dual target transcranial magnetic stimulation treatment in methamphetamine use disorder. The study will test intermittent theta burst stimulation (TBS) targeting the dorsolateral prefrontal cortex (DLPFC) combined with continuous TBS targeting the medial prefrontal cortex (MPFC) in people with methamphetamine use disorder (MAUD) who are engaged in psychosocial treatment. Intermittent TBS targeting the DLPFC is approved by the Food and Drug Administration for major depressive disorder, and continuous TBS targeting the MPFC has been studied in cocaine use disorder. We will administer this dual target TBS daily for 2 weeks, followed by three times weekly for 2 weeks, and monitor depressive symptoms, anxiety, sleep, craving, quality of life, and methamphetamine use for three months. Changes in functional connectivity of brain circuits will be evaluated with functional magnetic resonance imaging (fMRI) before and after treatment. We expect to observe changes in connectivity between the DLPFC, MPFC, and other regions implicated in addiction and impulsivity. Furthermore, we will evaluate if baseline differences in functional connectivity can be used to predict response. Psychological tests focusing on state impulsivity and risk taking will be administered, and we expect to observe reductions in these characteristics after treatment. We will test this protocol in 20 patients recruited from clinical care settings at University of Iowa Hospitals and Clinics, University of New Mexico Health System, and University of Utah Health to illustrate the feasibility of recruitment and completing the protocol, to support an external funding proposal.

The study aims to test whether transcranial magnetic stimulation (TMS) improves the craving, depression, anxiety and cognitive function during the abstinent period of methamphetamine users.

The main objective of this study is development of the Positive Peer Journaling (PPJ) intervention and the feasibility, acceptability, and logistics of treatment delivery. A second objective is to observe whether PPJ is associated with improvement in hypothesized outcomes. The primary outcomes the investigators will examine are enhanced treatment retention and reduced recurrence of substance use. The investigators will also explore the association between the intervention and a set of hypothesized mediators of the effect of the intervention on outcomes, e.g., improvement in mood and satisfaction with recovery.

This is a randomized controlled Phase II clinical trial designed to evaluate the effects of N-acetylcysteine (NAC) in reducing Alcohol Use Disorder (AUD) severity and Post Traumatic Stress Disorder (PTSD) symptomatology among individuals with current AUD and PTSD.

Bilateral (left cathodal/ right anodal) transcranial Direct Current Stimulation (tDCS) over the dorsolateral prefrontal cortex (DLPFC) seems to reduce craving and to increase the time till smoking the first cigarette after the intervention. The current study explores whether actual cigarette consumption decreases after repetitive tDCS. Cigarette consumption and craving will therefore be measured by means of EMA, before (at baseline), during and after multiple tDCS sessions, and at 3 months follow-up. To study the working mechanism behind the effects of tDCS, electrophysiological responses (ERPs) and behavioral measures of cognitive control functioning will be taken into account at baseline, one day after the last tDCS session and at three months follow up. We hypothesize that cigarette consumption will decrease after repetitive tDCS, and that this effect is associated with better cognitive control functioning.

This project examines computer-delivered cognitive-behavioral intervention (CBT4CBT) as an adjunct to residential treatment for women with substance use disorders (SUD). The project will conduct a 2-arm randomized clinical trial (RCT) comparing post-discharge relapse rates for treatment as usual (TAU) with access to the CBT4CBT program vs. TAU in a residential sample of women with SUDs.

Reinforcement-Based Therapy (RBT) is an intensive outpatient substance abuse treatment that includes relapse prevention skills training, goal setting, help with finding employment and abstinence-contingent rent payment for recovery housing in the community. It is meant to provide motivation for continued abstinence while enhancing social stability. In this study, treatment was offered to inner city opiate and cocaine users immediately following a brief medically-supported residential detoxification. Previous research had shown that RBT produces 3- month outcomes superior to those for patients who are referred to outpatient treatment in the community. The present study compared outcomes for patients (N = 243) randomly assigned to receive abstinence-contingent recovery housing with (full RBT) or without additional intensive counseling or to receive usual care referral to outpatient treatment following detoxification. Outcomes were similar at 3- and 6-month follow-ups for those who received recovery housing with (full RBT) and without additional counseling and both these treatments were superior to usual care referral. Study findings support the efficacy of post-detoxification recovery housing with or without counseling for opiate and cocaine users.
