Neuroimaging and psychosocial addiction treatment : an integrative guide for researchers and clinicians by Sarah W Feldstein Ewing( )

11 editions published in 2015 in English and held by 114 WorldCat member libraries worldwide

"Addiction might be an age-old affliction but we still only have a modest understanding of how and why addiction treatment works. This book uses an innovative translational approach to weave together basic biological (brain) mechanisms with human behaviour in order to provide a critical insight into why people do (and do not) change in the context of addiction treatment. With sections focusing on both adults and adolescents, this book bridges the gap between experimental scientists and clinical practitioners to provide an overview of the influence of basic brain functions."--

Neural activation during response inhibition is associated with adolescents' frequency of risky sex and substance use( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: Objective: Introduction: While many have identified the important role of the developing brain in youth risk behavior, few have examined the relationship between salient cognitive factors (response inhibition) and different types of real-world adolescent health risk behaviors such as substance use and risky sex, within the same sample of youth. Methods: We therefore sought to examine these relationships with 95 high-risk youth (ages 14-18; M age = 16.29 years). We examined blood oxygen level dependent (BOLD) response to an fMRI-based cognitive task designed to assess response inhibition (Go/NoGo) and past month risk behavior (number of substance use days; number of unprotected sex days). Results: For this sample of youth, we found significant negative correlations between past month substance use and response inhibition within the left inferior frontal gyrus (IFG) and right insula (uncorrected p <.001; extent threshold e"10 voxels). In addition, in the same contrast, we found significant positive correlations between past month risky sex and activation within the right IFG and left middle occipital gyrus (uncorrected p <.001; extent threshold e"10 voxels). Conclusions: These results suggest the particular relevance of these regions in this compelling, albeit slightly different, pattern of response for adolescent risky behaviors. Highlights: We evaluated response inhibition with two types of adolescent risk behavior. We found negative correlations between substance use and BOLD. This negative relationship was in the left inferior frontal gyrus (IFG) and right insula. We found positive correlations between risky sex and BOLD. This positive relationship was in the right IFG and left middle occipital gyrus
Introduction to the special issue: Substance use and the adolescent brain: Developmental impacts, interventions, and longitudinal outcomes( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: Adolescent substance abuse is a major public health problem, particularly given the negative brain and behavioral consequences that often occur during and following acute intoxication. Negative outcomes appear to be especially pronounced when substance use is initiated in the early adolescent years, perhaps due to neural adaptations that increase risk for substance use disorders into adulthood. Recent models to explain these epidemiological trends have focused on brain-based vulnerabilities to use as well as neurodevelopmental aberrations associated with initiation of use in substance naïve samples or through the description of case-control differences between heavy users and controls. Within this research, adolescent alcohol and marijuana users have shown relative decreases in regional gray matter volumes, substance-specific alterations in white matter volumes, deviations in microstructural integrity in white matter tracts that regulate communication between subcortical areas and higher level regulatory control regions, and deficits in functional connectivity. How these brain anomalies map onto other types of youth risk behavior and later vulnerabilities represent major questions for continued research. This special issue addresses these compelling and timely questions by introducing new methodologies, empirical relationships, and perspectives from major leaders in this field
Measurement invariance of alcohol instruments with Hispanic youth( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract: Introduction: Despite their widespread use across clinical and research settings, no study has yet investigated the fit of several standard alcohol measures for Hispanic youth, including those used to assess motivation to change, self-efficacy, peer norms, and problem drinking. This study thus served to address this gap by evaluating measurement invariance with substance-using youth. Methods: We enrolled a large sample of regular substance-using youth who were involved with the justice system ( N  = 368; 72.9% male; 76.9% Hispanic; M age = 16.17 years). Similar to the broader Hispanic population of the southwest United States (U.S.), Hispanic youth in the sample were on average 3.5th generation (with at least 1 foreign-born grand-parent). Following standard administration and scoring procedures, all youth completed measures of motivation to change (e.g., readiness rulers, intentions to change), self-efficacy (e.g., drink refusal in social situations), peer norms (e.g., peer norms for substance use), and problem drinking (e.g., substance use quantity/frequency; Alcohol Use Disorders Identification Test; Rutgers Alcohol Problems Index; Timeline FollowBack). Measurement equivalence was evaluated via multiple group confirmatory factor analysis. Results: Our results indicated that each measure evaluated herein worked equally well for Hispanic and Caucasian youth. We found measurement invariance at every level tested. Conclusions: This study supports the validity and future use of these important and widely-used alcohol use measures for high-risk substance-using Hispanic youth. Further, given the representativeness of this sample within the southwestern U.S., these results show promise for generalizability to U.S.-born Hispanic youth within this geographic region
