This script implements the original UPPS impulsive behavior scale 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. 

and made available by Dr. Lynam on:

45 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_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)

According to Whiteside & Lynam (2001) impulsivity encompasses four personality facets that are 
assessed in the UPPS impulse behavior scale: 
the 45 questions are assigned to the following facets:

1) Urgency: 2 (R), 6 (R), 10 (R), 14 (R), 18 (R), 24 (R), 28 (R), 32 (R), 36 (R), 41 (R), 43, 45 (R)
"measures an individual’s tendency to act “impulsively” under conditions of negative affect" *

2) (lack of) Premeditation: 1, 5, 9, 13, 17, 23, 27, 31, 35, 39, 40.
"assesses an individual’s tendency to act without consideration of the potential consequences of the behavior" *

3) (lack of) Perseverance: 4, 8 (R), 12, 16, 20, 22, 26, 30, 34, 38 (R)
"assesses an individual’s tendency to give up in the face of boredom, fatigue, or frustration." *

4) Sensation Seeking: 3 (R), 7 (R), 11 (R), 15 (R), 19 (R), 21 (R), 25 (R), 29 (R), 33 (R), 37 (R), 42 (R), 44 (R)
"refers to an individual’s interest in and tendency to pursue activities that are exciting and novel" *

(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.
