Examination of a short English version of the UPPS-P Impulsive Behavior Scale. Addictive Behaviors 39 (2014) 1372–1376. 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 ___________________________________________________________________________________________________________________ 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_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): 6(R), 8(R), 13(R), 15(R) "measures an individual’s tendency to act “impulsively” under conditions of negative affect" * 2) (lack of) Premeditation (PREM): 2, 5, 12, 19 "assesses an individual’s tendency to act without consideration of the potential consequences of the behavior" * 3) (lack of) Perseverance (PERS): 1, 4, 7, 11 "assesses an individual’s tendency to give up in the face of boredom, fatigue, or frustration." * 4) 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" * 5) 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 Items are initially scored on a scale from 1 (strongly agree) to 4 (strongly disagree) Items are then automatically reversed-scored where appropriate to reflect that higher values indicate more impulsive behavior 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" ___________________________________________________________________________________________________________________ EDITABLE CODE ___________________________________________________________________________________________________________________ check below for (relatively) easily editable parameters, stimuli, instructions etc. 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.
