BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements the SUPPS-P impulsive behavior scale as discussed in:

Cyders, MA, Littlefield, AK, Coffey, S, Karyadi, KA (2014).
Examination of a short English version of the UPPS-P Impulsive
Behavior Scale. Addictive Behaviors 39 (2014) 1372–1376.

Bulgarian UPPS:
Nikolova, S., Psederska, E., Bozgunov, K., Nedelchev, D., Vasilev, G., Vassileva, J. (under review). 
Psychometric characteristics of the Bulgarian version of the UPPS Impulsive Behavior Scale.

The original UPPS/UPPS-P scale was published by:

Whiteside, S. P., & Lynam, D. R. (2001). The Five Factor Model and impulsivity: using a structural 
model of personality to understand impulsivity. Personality and Individual Differences, 30(4), 669-689

and made availabe at: http://www1.psych.purdue.edu/~dlynam/uppspage.htm

Notes:
1. The question is order is different in the Inquisit Bulgarian version than the Inquisit English Version
2. The response anchors are reversed in the Inquisit Bulgarian version (not agreeing -> agreeing) 
compared to the Inquisit English one (agreeing -> not agreeing)

OVERVIEW
___________________________________________________________________________________________________________________
20 4-point Likert Questions regarding impulsive behavior

___________________________________________________________________________________________________________________	
DURATION 
___________________________________________________________________________________________________________________	
the default set-up of the script takes appr. 1.5 minutes to complete

__________________________________________________________________________________________________________________	
DATA FILE INFORMATION 
___________________________________________________________________________________________________________________	
The default data stored in the data files are:

(1) Raw data file: 'supps.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; responses DO reflect reversed scoring)
								Items are scored on a scale from 1 to 4; 
								higher scores reflect more impulsive behavior
								(where appropriate, responses are reversed (R) scored)
								
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: 'supps_p_bulgarian_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)	

Summarydata for each participant: 
file saves the scores for the subscales and totalscore (responses are reversed scored if appropriate)
Min (4) - Max (16) for each Subscale
Min (20) - Max (80) for totalscore => higher values indicate more impulsive behavior

//TotalScore
totalscore: sum of all subscale scores

//Subscales:
NURG: Negative Urgency (NURG): 6(R), 8(R), 13(R), 15(R), 
"measures an individual’s tendency to act “impulsively” under conditions of negative affect" *

PREM: (lack of) Premeditation (PREM): 2, 5, 12, 19
"assesses an individual’s tendency to act without consideration of the potential consequences of the behavior" *

PERS: (lack of) Perseverance (PERS): 1, 4, 7, 11
"assesses an individual’s tendency to give up in the face of boredom, fatigue, or frustration." *

SS: Sensation Seeking (SS): 9(R), 14(R), 16(R), 18(R)
"refers to an individual’s interest in and tendency to pursue activities that are exciting and novel" *

PURG: Positive Urgency (PURG): 3(R), 10(R), 17(R), 20(R)
"Positive Urgency, assesses an individual’s tendency to give in to impulses under conditions of high positive affect." 

(R) = reversed scoring

QUESTIONNAIRE SET-UP & SCORING
___________________________________________________________________________________________________________________

5 facets:

1) Negative Urgency (NURG): 1(R), 6(R), 11(R), 16(R) (in Bulgarian Version - BV)
"measures an individual’s tendency to act “impulsively” under conditions of negative affect" *

2) (lack of) Premeditation (PREM): 4, 9, 14, 19 (BV)
"assesses an individual’s tendency to act without consideration of the potential consequences of the behavior" *

3) (lack of) Perseverance (PERS): 2, 7, 12, 17 (BV)
"assesses an individual’s tendency to give up in the face of boredom, fatigue, or frustration." *

4) Sensation Seeking (SS): 5(R), 10(R), 15(R), 20(R) (BV)
"refers to an individual’s interest in and tendency to pursue activities that are exciting and novel" *

5) Positive Urgency (PURG): 3(R), 8(R), 13(R), 18(R) (BV)
"Positive Urgency, assesses an individual’s tendency to give in to impulses under conditions of high positive affect." *

(R) = reversed scoring

Items are scored on a scale from 1 to 4; 
higher scores reflect more impulsive behavior
(where appropriate, responses are reversed scored)

Note: Cyders et al (2014, table1) report to reverse score items that would actually result in lower 
scores for more impulsive behavior, despite the fact they also write that "Items with an (R) are reverse coded, 
so that higher values indicate more impulsive behavior".

Example q1: "I generally like to see things through to the end.* (R)"
"On a four point scale from 1 (strongly agree) to 4 (strongly disagree)", if one strongly agrees with this statement, 
the initial score of '1' would end up being coded as '4' as it's a R item; 
yet we think that agreeing to this statement is the opposite of impulsive behavior and should result in a 
low score not a high one.

In this script, we have thus coded all items in such a way that high scores on each question reflect a higher
degree of impulsivity. You can check the coding of each question under section QUESTIONS.
The final scores for each question can be referred from "/optionvalues"

Keep in mind that you can use this script as a template and therefore always "mess" with the entire code 
to further customize your experiment.
