ABSTRACT:

Objective

Clinical trials for substance use disorder (SUD) often assess outcomes by aggregating substance use data into weekly proportions. However, daily substance use patterns may reveal how motivation changes during treatment. Neurocognitive principles of recency and expectancy indicate the salience of treatment mechanisms would increase on days proximal to therapy sessions.
