These methods establish, among other things, whether items in a scale covary and whether this indicates latent traits to the construct under investigation. The present study was designed to apply an additional analytical tool to the NEO-FFI, to investigate whether or not the items in its scales form hierarchies. Mokken scaling is designed to search multivariate data for ...

A non-clinical sample (n = 132) completed the NEO-FFI personality inventory and the IIP-64C. In accordance with previous studies, Agreeableness and Extraversion were linked with IIP-64C, regardless of type of partitioning of the IIP-64C item set. Neuroticism had a strong association with interpersonal problems based on normative scores, but statistic ipsation removed this association. While the normative IIP-64C scores did not confirm the structural properties of the Circumplex model, the ipsatized scores did. In conclusion, the use of statistical ipsation of the IIP-64C could be a useful addition to traditional personality assessment procedures. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
