An investigation of the construct validity of three recently developed personality instruments: An application of confirmatory multimethod factor analysis

Abstract

The advantages of using confirmatory factor analysis in the analysis of multitrait‐multimethod (MTMM) matrices are discussed. This method is then applied to investigate the convergent and discriminant validity of three Australian developed personality instruments ‐ two measures of self‐esteem (Watkins, 1978) and the New England Personality Questionnaire (Fitzgerald & Cole, 1976). Examination of a MTMM matrix based on the responses of 275 university students generally supported the construct validity of these instruments. 1981 Australian Psychological Society
