This script implements the Barratt Impulsiveness Scale (BIS-11) described in:

Wai-Yee Chen (2013). Appendix B: Barratt Impulsiveness Scale (Revised)

original publication:
Patton, J.H., Standford, M.S., & Barratt, E.S. (1995). Factor Structure of the Barratt Impulsiveness Scale.
Journal of Clinical Psychology, 51, 768-774.

The default data stored in the data files are:

(1) Raw data file: 'BIS_revised.iqdat' 

date, time, group, subject:					date and time script was run with the current group/subjectnumber 
build:										the Inquisit build 

q*_response:								response given (in assigned values)
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_revised_summary*.iqdat' (a separate file for each participant)

script.startdate:							date script was run
script.starttime:							time script was started
script.subjectid:							subject id number
script.groupid:								group id number
script.elapsedtime:							time it took to run script (in ms)
computer.platform:							the platform the script was run on
/completed:									0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)
/totalscore:								the total score (across subscales)
/AttentionalFacetI:							score on Attentional Facet I (Range:5-20)
/AttentionalFacetII:						score on Attentional Facet II (Range:3-12)
/MotorFacetI:								score on Motor Facet I (Range:7-28)
/MotorFacetII:								score on Motor Facet II (Range:4-16)
/PlanningFacetI:							score on Planning Facet I (Range:6-24)
/PlanningFacetII:							score on Planning Facet II (Range:5-20)
/BIS_totalscore:							the sum of all subscores

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. 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


/presentFeedback:		true(1) - default: presents feedback at the end
						false(0): does not present feedback at the end
