The identification of random or careless responding in questionnaires as exemplified by the NEO-FFI
Journal Title: Roczniki Psychologiczne - Year 2014, Vol 17, Issue 2
Abstract
The article presents two little-known indices of random or careless responding: Cattell's sabotage index and fixed individualized chance (FIC) score. Both indices are used to identify people who provide content-irrelevant answers, such as random ones, in multidimensional questionnaires. The aim of the study was to verify empirically the diagnostic applications of these indices in distin-guishing the actual NEO-FFI scores from random data generated by a computer. The study in-volved 943 participants and 1000 randomly generated protocols. Based on both indices in combi-nation and using logistic regression, it proved possible to distinguish the actual data from the random data fairly well. Approximately 86% of all data was classified correctly. This result is quite high, given that some participants might have responded to the NEO-FFI items in a random way.
