The association between executive functioning and motivation to enter treatment among regular users of heroin and/or cocaine in Baltimore, MD.

This study explored the association between readiness to enter treatment and performance on the Wisconsin Card Sorting Test (WCST), a measure of problem solving ability and executive functioning. Data for this analysis was collected on 258 current regular users of heroin and/or cocaine as part of an epidemiologic study on executive function and drug use. A structural equation model was used to test the hypotheses that poorer performance on the WCST would predict lower scores on two latent constructs measuring motivation to change drug use.
