Abstract
Two of the best multivariate mood-state scales are the Differential Emotions Scale (DES-IV) and the Eight State Questionnaire (8SQ). Both instruments purportedly measure several different fundamental emotions. In many situations, though, the measurement of numerous different mood states may be somewhat time-consuming and inefficient. As fundamental emotions are at the Cattellian source-state level, it would seem useful to elucidate secondary factors at the Eysenckian typological level of analysis. Clearly, a smaller set of mood-type factors would provide greater economy of measurement and administration time. Moreover, delimitation of secondary factors should add to the usefulness and flexibility of the two instruments. The present paper reports a higher-order scale dR-factoring of the 8SQ and DES-IV instruments on a sample of 212 undergraduate students.
