Construct validity of sensation seeking and curiosity measures of normal and psychotic subjects.

Abstract
Self-report and performance measures of curiosity were examined for internal consistency, discriminant validity from social desirability, intelligence and anxiety measures, and for convergent validity [in schizophrenic patients and normal subjects]. In performance tasks generalizability of results from random polygons to art products was examined. Results showed self-report measures were limited psychometrically and were not unitary scales, while performance measures confounded method and stimulus variance. Both types of measure overlapped with discriminant variables, but self-report measures overlapped more. Convergent validity was greater for self-report than performance tests. No factor united all variables. There was some support for generalizing from polygons to paintings.
