A multitrait-multimethod examination of affect structure: hedonic level and emotional intensity

Past research on the personality structure of affect suggests that hedonic level and emotional intensity are two separate major dimensions. The present study employed a multitrait-multimethod approach to verify this finding. Seventy-four University of Illinois students completed daily mood reports and self-report questionnaires, and their parents completed a questionnaire about them. Both hedonic level and intensity measures were used. The convergent validities (monotrait-multimethod correlations) were all significant and tended to be highest for emotional intensity. The multitrait-monomethod coefficients were nonsignificant, as were the correlations based on different measures of different traits. The data were interpreted as supporting the distinction between hedonic level and affect intensity, as well as supporting the validity of the measures.
