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

Patton, J.H., Standford, M.S., & Barratt, E.S. (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_italian.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_italian_summary*.iqdat' (a separate file for each participant)

computer.platform:				the platform the script was run on (win/mac/ios/android)
script.startdate:					date script was run
script.starttime:					time script was started
script.subjectid:					assigned subject id number
script.groupid:					assigned group id number
script.sessionid:					assigned session id number
script.elapsedtime:				time it took to run script (in ms); measured from onset to offset of script
script.completed:					0 = script was not completed (prematurely aborted); 
								1 = script was completed (all conditions run)

'A_Attention'-'NP_CogComplex':		the scores for each individual subscale
totalscore:						the total score (across subscales)

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
