Each question is presented with 4 answer choices (-> "nie/selten", "manchmal", "oft", "fast immer/immer"). Each of the questions belongs to 6 subscales (derived from 6 first order factors and 3 first order factors) 1. Attention-Attention: 5, 9R, 11, 20R, 28 2. Attention-Cognitive Instability: 6, 24, 26 3. Motor-Motor: 2, 3, 4, 17, 19, 22, 25 4. Motor-Perserverance: 16, 21, 23, 30R 5. Nonplanning-Self Control: 1R, 7R, 8R, 12R, 13R, 14 6. Nonplanning-Cognitive Complexity: 10R, 15R, 18, 27, 29R (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
