(1995). Factor Structure of the Barratt Impulsiveness Scale. Journal of Clinical Psychology, 51, 768-774. ___________________________________________________________________________________________________________________ DURATION ___________________________________________________________________________________________________________________ the default set-up of the script takes appr. 2 minutes to complete ___________________________________________________________________________________________________________________ DATA FILE INFORMATION ___________________________________________________________________________________________________________________ The default data stored in the data files are: (1) Raw data file: 'bis.iqdat' date, time: date and time script was run with the current group/subjectnumber subject, group, session: with the current subject/groupnumber/session id build: the Inquisit build q*_response: response given (in assigned values) Scale: 1 (rarely never) - 4 (almost always) R = automatically reversed scored questions q*_latency: how much time (in ms) the participant spent on the surveypage with this particular question (the last time this particular surveypage was visited) (2) Summary data file: 'bis_summary*.iqdat' (a separate file for each participant) inquisit.version: Inquisit version run computer.platform: the platform the script was run on (win/mac/ios/android) startDate: date script was run startTime: time script was started subjectid: assigned subject id number groupid: assigned group id number sessionid: assigned session id number elapsedTime: time it took to run script (in ms); measured from onset to offset of script completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run) //Subscale Scores A_Attention: Attention-Attention subscale score: questions 5, 9R, 11, 20R, 28, Range: 5-20 A_CogInstabile: Attention-Cognitive Instability subscale score: questions 6, 24, 26, Range: 3-12 M_Motor: Motor-Motor Subscale Score: questions 2, 3, 4, 17, 19, 22, 25, Range: 7-28 M_Perserverance: Motor-Perserverance Subscale Score: questions 16, 21, 23, 30R, Range: 4-16 NP_SelfControl: Nonplanning-Self Control Subscale Score: questions 1R, 7R, 8R, 12R, 13R, 14, Range: 6-24 NP_CogComplex: Nonplanning-Cognitive Complexity Subscale Score: questions 10R, 15R, 18, 27, 29R, Range: 5-20 (R = reversed scoring, depends on wording) //Total Score: totalscore: the total score (sum of all subscale scores), Range: 30-120 //Individual Scores on each questions radiobuttons.q1_R.response, radiobuttons.q2.response, radiobuttons.q3.response, radiobuttons.q4.response, radiobuttons.q5.response, radiobuttons.q6.response, radiobuttons.q7_R.response, radiobuttons.q8_R.response, radiobuttons.q9_R.response, radiobuttons.q10_R.response, radiobuttons.q11.response, radiobuttons.q12_R.response, radiobuttons.q13_R.response, radiobuttons.q14.response, radiobuttons.q15_R.response, radiobuttons.q16.response, radiobuttons.q17.response, radiobuttons.q18.response, radiobuttons.q19.response, radiobuttons.q20_R.response, radiobuttons.q21.response, radiobuttons.q22.response, radiobuttons.q23.response, radiobuttons.q24.response, radiobuttons.q25.response, radiobuttons.q26.response, radiobuttons.q27.response, radiobuttons.q28.response, radiobuttons.q29_R.response, radiobuttons.q30_R.response ___________________________________________________________________________________________________________________ QUESTIONNAIRE SET-UP & SCORING ___________________________________________________________________________________________________________________ The questionnaire contains 30 questions. 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. 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
