SECONDARY outcome

Timeframe: 48 days

Population: Eight subjects participants in each condition in a within-subjects fashion.

Visual analogue scale ratings on the 'Drug Quality' cluster as a function of cocaine dose and modafinil maintenance condition. A cluster score was derived by taking the arithmetic average of the items in the cluster. Scores range from 0-100, with higher scores indicating greater agreement with the term. The "Drug Quality Cluster" consisted of three items: 1. "the choice was of high quality" 2. "the choice was potent" 3. "I liked the choice" Higher scores indicate increasing agreement with the statement, which would indicate a poorer outcome.
