dc.description.abstract This paper is the second in a series documenting and validating the MiniIPIP6 for use in New Zealand. The Mini-IPIP6 is a public domain shortform personality instrument which provides four-item markers of the six broad-bandwidth dimensions of personality: Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness to Experience and HonestyHumility. This study reports results from an Item Response Theory analysis of the Mini-IPIP6 in a nationally representative New Zealand sample (N = 5,576). A series of unidimensional graded item response models indicated that the Mini-IPIP6 provided well distributed estimates of each of the six dimensions of personality across the latent trait range and centered on the population mean. These findings indicate that the Mini-IPIP6 provides a reasonably precise measure of the major dimensions of personality, given the scale’s brevity. Discrimination and difficulty parameter estimates for the Mini-IPIP6 in the New Zealand population are presented, along with Test Information Functions for each personality dimension. A copy of the MiniIPIP6 is included. en
