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.
0.5 minutes
10 7-point Likert questions: 2 for each of the 5 personality domains
(Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openeness)
slightly adapted from Gosling et al (2003) to reflect a different testing setup.
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)
