BACKGROUND INFO
___________________________________________________________________________________________________________________
This script implements a computerized version of the Ten Item Personality Inventory (TIPI) described in:
Gosling, S. D., Rentfrow, P. J., & Swann, W. B. Jr. (2003). A very brief measure of the Big-Five personality domains.
Journal of Research in Personality, 37, 504–528.
___________________________________________________________________________________________________________________
OVERVIEW
___________________________________________________________________________________________________________________
10 7-point Likert questions: 2 for each of the 5 personality domains
(Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openeness)
___________________________________________________________________________________________________________________
DURATION
___________________________________________________________________________________________________________________
the default set-up of the script takes less than 1 minute
___________________________________________________________________________________________________________________
DATA FILE INFORMATION
___________________________________________________________________________________________________________________
The default data stored in the data files are:
(1) Raw data file: 'tipi.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 (disagree strongly) - 7 (agree strongly)
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: 'tipi_summary.iqdat' (Inquisit Lab: one data file per 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)
Range: 1-7 => the higher the score the higher the particular facet has been affirmed by participant
expressions.Extraversion: mean Extraversion score
expressions.Agreeableness: mean Agreeableness score
expressions.Conscientiousness: mean Conscientiousness score
expressions.EmotionalStability: mean Emotional Stability score
expressions.Openeness: mean Openeness score
Norms:
parameters.calculateGenderPercentile: true (1) = z-score and percentiles are calculated based on gender norms (provided by Gosling et al, 2003, p.526) - can be set under Editable Parameters
false (0) = z-score and percentiles are calculated using the overall norms (provided by Gosling et al, 2003, p.526)
radiobuttons.gender.response: 1 = female; 2 = male; empty (=> question wasn't asked)
/z_E: calculated z-score of the Extraversion score (based on data provided by Gosling et al, 2003, p.526)
/E_percentile: z-score percentile of the Extraversion score (based on data provided by Gosling et al, 2003, p.526)
/z_A: calculated z-score of the Agreeableness score (based on data provided by Gosling et al, 2003, p.526)
/A_percentile: z-score percentile of the Agreeableness score (based on data provided by Gosling et al, 2003, p.526)
/z_C: calculated z-score of the Conscientiousness score (based on data provided by Gosling et al, 2003, p.526)
/C_percentile: z-score percentile of the Conscientiousness score (based on data provided by Gosling et al, 2003, p.526)
/z_ES: calculated z-score of the Emotional Stability score (based on data provided by Gosling et al, 2003, p.526)
/ES_percentile: z-score percentile of the Emotional Stability score (based on data provided by Gosling et al, 2003, p.526)
/z_O: calculated z-score of the Openeness score (based on data provided by Gosling et al, 2003, p.526)
/O_percentile: z-score percentile of the Openeness score (based on data provided by Gosling et al, 2003, p.526)

QUESTIONNAIRE SET-UP & SCORING
___________________________________________________________________________________________________________________
10 7-point Likert questions
- 2 for each of the 5 personality domains (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openeness)
- one of the two questions is reversed scored (automatically done by the program)
- if parameters.calculateGenderPercentile is set to 'true', a gender question is provided at the end of the questionnaire
(by default, the gender question is omitted)
Scoring:
* computer automatically calculates the average score for the 5 categories
* computer automatically calculates the z-score and percentile values of the 5 scores based on data published by
Gosling et al (2003)
-> by default, overall means across gender and ethnic groups are used
-> if parameters.calculateGenderPercentile is set to 'true', percentiles are calculated based on the reported gender
(across ethnic groups)

INSTRUCTIONS

slightly adapted from Gosling et al (2003) to reflect a different testing setup.

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.
The parameters you can change are:
/pageinstructions: the instructions posted on top of each page of the questionnaire
/calculateGenderPercentile: true (1) = z-score and percentiles are calculated based on gender norms (provided by Gosling et al, 2003)
false (0) = z-score and percentiles are calculated using the overall norms (provided by Gosling et al, 2003)
