The mini IPIP scales: tiny yet effective measures of the Big Five factors of personality.
The Mini IPIP, a 20 item short form of the 50 item International Personality Item Pool Five Factor Model measure (Goldberg, 1999) was developed and validated across five studies. The Mini IPIP scales, with four items per Big Five trait, had consistent and acceptable internal consistencies across five studies at or well above .60) similar coverage of facets as other broad Big Five measures (Study 2) and test retest correlations that were quite similar to the parent measure across intervals of a few weeks (Study 4) and several months (Study 5) Moreover, the Mini IPIP scales showed a comparable pattern of convergent, discriminant, and criterion related validity (Studies 2 5) with other Big Five measures. Collectively, these results indicate that the Mini IPIP is a psychometrically acceptable and practically useful short measure of the Big Five factors of personality.
