Each question is presented with 4 answer choices (-> "Rarely/Never", "Occasionally", "Often", "Almost Always/Always"). Each of the questions belongs to 6 subscales (derived from 6 first order factors and 3 first order factors) 1. AttentionalFacet I: 1, 2R, 3, 4R, 5 2. AttentionalFacet2: 6, 7, 8 3. MotorFacetI: 9, 10, 11, 12, 13, 14, 15 4. MotorFacetII: 16, 17, 18, 19R 5. PlanningFacetI: 20R, 21R, 22R, 23R, 24R, 25 6. PlanningFacetII: 26R, 27R, 28, 29, 30R (R = reversed scoring, depends on wording) Scoring: on a 4-point scale "1" for least Impulsive choice to "4" for most Impulsive choice => Minimum Score: 30 => Maximum Score: 120 EDITABLE CODE: /presentFeedback: true(1) - default: presents feedback at the end false(0): does not present feedback at the end
