In order to categorize the items of the Zung Self‐Rating Depression Scale (SDS) so as to allow the construction of subscales, the Japanese version of the SDS was administered to a total of 2,258 undergraduates. Principal–component analyses of the SDS extracted three factors interpretable as cognitive, affective, and somatic symptoms. The SDS was then administered to 597 undergraduates in order to cross‐validate the factor structures. The coefficient of congruence and the goodness‐of‐fitness index generated by a confirmatory factor analysis showed good cross‐validity of the factor structures. © 1998 John Wiley & Sons, Inc.
