Personality composite scores
We are looking to use some of the personality measures for our analysis; and it would be really useful to know how the composite scores were calculated. Was factor analysis used? If so, what kind of rotation and extraction methods were used? Thank you for your help in advance!

Hello Y Hu,
No factor analysis was not used. The standard approach of measuring the Big 5 personality traits based on the 15 item module was used.
Each respondent is asked to rate 15 questions on how they see themselves on a 7-point scale, from 1 “does not apply” to 7 “applies perfectly”. Each of the Big 5 personality trait score is computed as the average score of the responses to the three questions pertaining to that trait. The variable names show which question is used for which trait: the last letter refers to the trait (O=openness to experience, C=conscientiousness, E=extraversion, A=Agreeableness, N=Neuroticism). These are
Openness to Experience: c_scptrt5o1-c_scptrt5o3
Note these items are reverse coded: c_scptrt5c2, c_scptrt5e3,c_scptrt5a1,c_scptrt5n3
Hope this helps.
