Multidimensional Scaling Of The Eight State Questionnaire And The Differential Emotions Scale, Gregory J. Boyle, Ilana Katz
Multidimensional Scaling Of The Eight State Questionnaire And The Differential Emotions Scale, Gregory J. Boyle, Ilana Katz
Gregory J. Boyle
While the interrelationships between multivariate measures of mood states have been analysed using various statistical procedures including exploratory factor analysis, discriminant function analysis, multiple regression analysis, and canonical-redundancy analysis, the techniques of Multidimensional Scaling (MDS) however, have been used less extensively in psychometric research. MDS provides a readily interpretable representation of empirical relationships between different sets of data. The present study attempted to replicate Boyle's (1986a; Psychological Reports, 59, 503–510) factor analytic findings on two self-report multidimensional mood-state measures, namely the Eight State Questionnaire (8SQ), and the Differential Emotions Scale (DES-IV), to demonstrate the utility of MDS to uncover the …

The Eight State Questionnaire (8SQ) is a comprehensive self-report inventory which has been used in numerous studies of multidimensional mood states. The 8SQ has been useful in clinical situations for evaluating the efficacy of various therapeutic interventions, as well as in other contexts. The instrument takes about 20-25 minutes to administer, thereby enhancing its usefulness as a quick measure of transitory, constantly fluctuating mood states. Nevertheless, examination of the congeneric factor structure of the 8SQ subscales suggests that a number of the items are complex, contributing significantly to more than one subscale dimension. Both exploratory and confirmatory factor analyses have …
