Confirmatory factor analysis of the M5-50: an implementation of the International Personality Item Pool item set.
Goldberg's International Personality Item Pool (IPIP; Goldberg, 1999) provides researchers with public-domain, free-access personality measurement scales that are proxies of well-established published scales. One of the more commonly used IPIP sets employs 50 items to measure the 5 broad domains of the 5-factor model, with 10 items per factor. The M5-50 (McCord, 2002) is a specific ordering and presentation of this 50-item set. Using data from a sample of 760 faculty, staff, and students at a midsized university, the authors assessed the reliability and construct validity of the M5-50. Cronbach's alphas on the 5 scales ranged from acceptable to excellent. Confirmatory factor analysis indicated reasonably good model fit. Researchers who wish to measure personality would be well advised to consider using the M5-50.
