结局指标
主要结局
Change in SUbjective Effects as Assessed by Score on "Feel Drug", "Feel High", "Like Drug", and "Want More" Sub-scales of Drug Effects Questionnaire (DEQ).
时间窗: Time Frame: Day 1(baseline), 3
Participants will complete The Drug Effects Questionnaire during the initial baseline session to determine their subjective stimulant profile. The Dug Effects Questionnaire (DEQ) is a visual analog scale questionnaire that assesses the extent to which subjects experience four subjective states: "Feel Drug", "Feel High", "Like Drug", and "Want More". All sub-scales are scored on a visual analogue scale (Scroll bar on computer screen) ranging from 0-100. 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome.
