This script implements the UPPS-P impulsive behavior scale made available by Dr. Lynam on:

The original UPPS was based on 4 facets of impulsivity and was originally described in:
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. 

The edited version UPPS-P adds a fifth personality facet to the construct of impulsivity.

59 4-point Likert Questions regarding impulsive behavior

The default data stored in the data files are:

(1) Raw data file: 'UPPS.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; responses DO reflect reversed scoring) 
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: 'UPPS_P_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)
Summarydata for each participant: file saves the scores for the subscales and totalscore (responses are reversed scored if appropriate)

original 4 facets:
1) Negative Urgency: 2 (R), 67(R), 12 (R), 17 (R), 22 (R), 29 (R), 34 (R), 39 (R), 44 (R), 51 (R), 54, 58 (R)
"measures an individual’s tendency to act “impulsively” under conditions of negative affect" *

2) (lack of) Premeditation: 1, 6, 11, 16, 21, 28, 33, 38, 43, 48, 49.
"assesses an individual’s tendency to act without consideration of the potential consequences of the behavior" *

3) (lack of) Perseverance: 4, 9 (R), 14, 19, 24, 27, 32, 37, 42, 47 (R)
"assesses an individual’s tendency to give up in the face of boredom, fatigue, or frustration." *

4) Sensation Seeking: 3 (R), 8 (R), 13 (R), 18 (R), 23 (R), 26 (R), 31 (R), 36 (R), 41 (R), 46 (R), 52 (R), 56 (R)
"refers to an individual’s interest in and tendency to pursue activities that are exciting and novel" *

added facet:
5) Positive Urgency: 5 (R), 10 (R), 15 (R), 20 (R), 25 (R), 30 (R), 35 (R), 40 (R), 45 (R), 50 (R), 53 (R), 55 (R), 57 (R), 59 (R)
"Positive Urgency, assesses an individual’s tendency to give in to impulses under conditions of high positive affect." *

(R) = reversed scoring
* = see web site above

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.
