Abstract: | After reading Dorothy Adkins' heroic attempt (American Psychologist, 1954, 9, 175-180) to analyze the structure of the APA by factor analysis, the present author attempted a cluster analysis of her correlation matrix. The aim was to see whether or not results equally as satisfactory as those achieved by factor analysis could be obtained by the shorter method.
