Filter by:Deviant peer affiliation is one of the most important predictors of alcohol use in adolescence. These affiliations arise when socially marginalized youth self-aggregate and reinforce alcohol use and other deviant activity (i.e., "deviant peer clustering"). Existing efficacious school-based prevention programs generally have small effects and can be difficult to disseminate with fidelity and challenging to sustain due to complex designs and significant time-and-money expenditures required for materials and training. Existing school-based prevention programs have not provided compelling value to schools, which has limited their dissemination. The investigators found significantly lower rates of deviant peer affiliation and alcohol/tobacco use and moderate-to-strong suppressive effects on bullying, victimization, stress, and emotional problems, and strong positive effects on student engagement, achievement, and social-emotional skills in peer-learning intervention schools compared to control schools. However, teachers in intervention schools faced challenges implementing peer learning, including: (1) design fidelity: ensuring that peer learning provided the most positive student experience by including all the essential design elements; and, (2) instructional support: managing the flow and timing of the activities to complete the lesson on time while dealing with unexpected disruptions. Investigators developed an initial version of a mobile software application (PeerLearning.net) that provided easy-to-use organizational templates with workflow support that teachers used to automate the design and delivery of peer learning lessons. In this cluster randomized trial of the app, the investigators will use a sample of middle and high schools and conduct pre/post student assessments of peer relations, alcohol/drug use, antisocial/prosocial behavior, and social-emotional skills. They will also collect information on stress, bullying/victimization and related outcomes, including sleep quality and mental health. Investigators will also collect data on the frequency of lesson delivery with the app by teacher and school to assess dosage, which will be incorporated into our analyses. The investigators hypothesize that use of PeerLearning.net will have significant suppressive effects on alcohol use and related outcomes (i.e., tobacco/marijuana use, antisocial behavior, bullying, emotional problems) and promote increased levels of social-emotional skills and prosocial behavior. The investigators hypothesize that these results will be moderated by dosage (i.e., use of the app), such that greater usage yields larger effects.
This study explores the efficacy and feasibility of a self-management wellness intervention that is integrated, prescriptive, and trackable in a population of registered nurses in the state of Texas enrolled in the TExas Peer Assistance Program for Nurses (TPAPN). This 30-day wellness intervention (called "KickStart30") combines five wellness elements: exercise,mindfulness, sleep, social connectedness, and nutrition. Additionally, the program requires that participants implement 5 wellness interventions daily for the 30-day study, document daily online adherence, complete daily HERO (happiness, enthusiasm, resilience, and optimism) exercises to improve mental wellness, and complete online program forms before and after the 30-day intervention. Participants are assessed pre- and post-intervention to determine whether the intervention promotes wellness behavior changes.
The purpose of this study is to develop and evaluate an intervention that adapts Community Reinforcement and Family Training (CRAFT) for families experiencing first episode psychosis and substance use delivered via telemedicine (video conferencing). The intervention aims to improve treatment engagement and reduce distress, and it will be delivered via telemedicine (CRAFT-FT). To assess feasibility of the intervention, family members will complete the sessions and provide feedback to refine the treatment manual. Data on client relatives with psychosis will be collected for preliminary assessment purposes. Client relatives will not complete the research study intervention.
The purpose of this study is to evaluate the feasibility and effectiveness of a peer-led, brief, behavioral intervention to improve adherence to medication for opioid use disorder (MOUD) among low-income, minoritized individuals living with opioid use disorder (OUD) in Baltimore, Maryland. The intervention is based on behavioral activation (BA) and is specifically designed to be implemented by a trained peer recovery specialist. In this pilot trial, the investigators will evaluate the feasibility, acceptability, and fidelity of this approach (implementation outcomes) and preliminary effectiveness on methadone treatment retention at three months.
The specific aim of this study is to evaluate the performance of three substance use screening instruments (S2BI, BSTAD, and TAPS Tool) against a criterion standard of Diagnostic Statistical Manual - 5 (DSM-5) substance use disorder (SUD) diagnoses in an adolescent population.
The SAFE study examines the effects of brief mindfulness-based cognitive-behavioral intervention aimed at improving risk-related attention skills (risk detection, problem solving, assertiveness, and help seeking) in order to reduce substance use and victimization among young people (ages 18-21) experiencing homelessness.
This study will be the first to explore mindfulness as a prevention intervention among transition age youth and those with previous involvement in the juvenile or criminal justice system with substance use problems and history of exposure to violence/trauma. The study will focus on preventing escalation of substance use (e.g., alcohol and marijuana), trauma symptoms, and recidivism by using an intervention to target self-regulation and executive functioning. Justice involved youth have higher rates of alcohol use and related consequences and higher rates of exposure to violence (Post Traumatic Stress Disorder) compared to their non-justice involved peers. Prior research has found aspects of self-regulation (emotion regulation, impulse control), stress, and craving to be important putative targets in reducing alcohol use. With high rates of recidivism and increased risk of long term problems associated with substance use, it is imperative to test interventions that can reach at risk youth and target both alcohol use and important psychological and neurocognitive self-regulation mechanisms. This study tests whether the use of Mindfulness-Based Relapse Prevention (MBRP) for at risk young adults results in changes in important self-regulation mechanisms and improved alcohol use outcomes. Individuals assigned to the experimental group will receive interventions normally provided at a community clinic and eight 1.5-hour group sessions of MBRP. Sessions will occur once per week. Each session will target a specific theme such as being aware of personal triggers, maintaining present focus, allowing or letting things be, responding to emotional and physical experiences in skillful ways, and recognizing intrusive thoughts. Further, each session will incorporate a mindfulness meditation technique. The central hypothesis will be tested through a focus on three specific aims: (1) Beta pilot testing and refining MBRP based on feedback from focus groups, (2) testing the efficacy of MBRP on substance use outcomes compared to an active control, and (3) assessing mechanisms of change for MBRP including self-regulation and neurocognitive facets such as working memory and inhibition.
This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.
This study will test the effects of an intervention to reduce substance use and related harms among people leaving rural jails or otherwise involved in the criminal justice system. This study will compare people in a health linkage intervention with people who will get overdose (OD) education. Everyone will take part in the baseline and follow-up surveys and receive OD education. Participants will be assigned to one of the two groups by chance based on when they are enrolled to the study and if their county is randomly assigned to an intervention or a comparison condition. By doing this study, the investigators hope to learn if providing linkage to health services along with HIV, hepatitis C virus (HCV), and overdose education to people leaving rural jails or otherwise involved in the criminal justice system will reduce substance use and related harms.
In Hong Kong, methamphetamine use is common and cocaine use has increased steadily over the past few years. While the use of ketamine decreased from 35.8% in 2015 to 13.9% in 2017, methamphetamine and cocaine have become the most commonly used psychotropic substances and account for more than 50% of drug abuses cases in 2017. Among all stimulants, methamphetamine is most commonly used because it releases three times more dopamine than cocaine and the effects can last from eight to twelve hours, compared to two hours for cocaine. On top of its extreme effects, methamphetamine is relatively inexpensive, making it even more accessible to the young population. Misuse of methamphetamine has long been associated with profound psychological and cognitive disturbance. In reviewing the cognitive data from reasonably well-matched groups of chronic methamphetamine users and healthy controls, the majority of studies have found that chronic methamphetamine users had lower scores on at least some cognitive tests, although some studies are exceptions with entirely nonsignificant differences. A meta-analysis of 17 cross-sectional studies found that chronic methamphetamine users demonstrated significantly lower cognitive scores than healthy controls. The effects were largest for measures of learning, executive functions, memory, and processing speed, although the majority of cognitive domains significantly differed between the groups. Concerns has been emerging regarding the methodology of the aforementioned results. In particular, the appropriateness of using healthy controls to examine the cognitive effects of stimulant use has been questioned. Much of the published research has fallen victim to using controls with significant baseline differences from the chronic stimulant users, such as years of education. In addition, none of the studies available provided scatter plots of their cognitive data to evaluate the overlap in performance between chronic stimulant users and healthy controls. In fact, many chronic stimulant users have normal cognitive function when compared with normative data. Therefore, the use of the term 'impairment' or 'deficit' in many studies is not fully justified. Another limitation is that it cannot differentiate cognitive weaknesses that may predate stimulant use from those that result from it. Notably, longitudinal studies have shown that childhood deficits in executive function can predict drug abuse in adolescence, suggesting that at least some of the cognitive weaknesses pre-exist in chronic stimulant user. These and other limitations provoked a conclusion that the evidence for cognitive deficits in chronic stimulant users is weak. In order to overcome the methodological issues observed in previous cross-sectional studies, we propose to conduct a prospective studies to determine the change in cognitive function among stimulant users over time.
