Wanous, Reichers, and Austin's (2000) measure of cynicism about organizational change (CAOC) was subjected to validation and cross-validation procedures using data collected from two Australian public sector organizations. More specifically analyses were conducted to determine whether CAOC is best understood as a single dimensional or a two dimensional construct. The results of confirmatory factor analysis suggest that neither a one dimensional nor a two dimensional measurement model provided a satisfactory fit to the data. However, removal of two of the original eight items resulted in a two dimensional model, with three items in each dimension, that provided a reasonable fit to the data. Practical implications and directions for future research are discussed.
