The construct validity of a 10-item scale oriented to measure traditional culture, the Organizational Culture Scale of Artifacts, was analyzed under the hypothesis of unidimensionality. Confirmatory factor analysis took into account the method effects associated with reverse-worded items. Based on the data from one-half of a sample of 926 participants (79.8% male; M age = 33.4 yr., SD = 12.8), working in different companies supported a unidimensional structure, with the elimination of two items from the scale. The resulting 8-item scale was reanalyzed, this time with the second half of the split sample. Support was found for the scale's unidimensionality with this second data set.
