title: Factor structures of the Zung Self-Rating Depression Scale (SDS) for undergraduates.
abstract: 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.
