简要总结
This 2-arm study will recruit participants with 1) alcohol use disorder and 2) cannabis use disorder for a 12-week cognitive behavioral therapy, following a thorough baseline assessments on executive function, incentive salience, and negative emotionality.
详细描述
Although effective evidence-based interventions have been developed for alcohol and cannabis use disorders, it is still unclear which individuals respond best to treatment. A recent model known as the Addictions Neuroclinical Assessment (ANA) proposes that assessing for differences in three neurofunctional domains (executive function, incentive salience, and negative emotionality) could allow for a stronger neuroscience-based framework for understanding heterogeneity in response to addiction treatments but this has never been tested prospectively. In this study, we will recruit two groups: (1) participants with alcohol use disorder (AUD) and (2) participants with cannabis use disorder (CUD). Participants will undergo thorough baseline assessments of each of the three ANA domains prior to evidence-based treatment for their respective disorders. Individuals with AUD will be treated with 12 weeks of cognitive behavioral therapy (CBT) for AUD plus optional pharmacotherapy guided by a pharmacotherapy algorithm. Individuals with CUD will be treated with 12 weeks of CBT + motivational enhancement therapy for CUD. The primary objective of the study is to assess whether baseline ANA measures are associated with changes in drug consumption and craving over treatment.
