Alcohol and cannabis misuse are related to impaired cognition. When inferring causality, four nonexclusive theoretical models can account for this association: 1) a common underlying vulnerability model; 2) a neuroplasticity model in which impairment is concurrent with changes in substance use but temporary because of neuroplastic brain processes that restore function; 3) a neurotoxicity model of long-term impairment consequential to substance use; and 4) a developmental sensitivity hypothesis of age-specific effects. Using a developmentally sensitive design, the authors investigated relationships between year-to-year changes in substance use and cognitive development. Method: A population-based sample of 3,826 seventhgrade students from 31 schools consisting of 5% of all students entering high school in 2012 and 2013 in the Greater Montreal region were assessed annually for 4 years on alcohol and cannabis use, recall memory, perceptual reasoning, inhibition, and working memory, using school-based computerized assessments. Multilevel regression models, performed separately for each substance, were used to simultaneously test vulnerability (between-subject) and concurrent and lagged within-subject effects on each cognitive domain.
This review article presents a summary of the existing literature on well-established CBT treatments for substance use disorder. It provides an overview of the origins, procedure, and evidence for six CBT treatment models: relapse prevention (RP) and mindful-based relapse prevention (MBRP), guided self-change (GSC), community reinforcement approach (CRA), behavioral couples therapy (BCT), and personality-targeted brief interventions. Common intervention components include orienting clients towards a meaningful goal, teaching necessary skills to reduce substance use and successfully achieve the goal, and establishing plans to face potential relapses, which generally appear to produce moderate to large effects across contexts and substance-related outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
