Advanced Analytic Methods Could Provide Insight Into Mechanisms of Behavior Change

by

Numerous evidence-based behavioral interventions for alcohol use disorder (AUD) are available, including cognitive behavioral therapy, couples therapy, 12-step facilitation, and motivational interviewing. A current focus of research on behavioral interventions for AUD is identifying the processes through which evidence-based interventions work. Known as mechanisms of behavior change (MOBCs), such as increased readiness to change, increased … Read more

MicroRNAs, or miRNAs, are short strands of RNA that play important roles in gene regulation. In two recent studies, researchers supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) identified two miRNAs that may help protect against alcohol-induced liver injury. Paramananda Saikia, Ph.D., and colleagues at the Cleveland Clinic, in studies conducted in … Read more
