    Dissociation : Vol. 4, No. 4, p. 185-188 : Construct validity of the Dissociative Experiences Scale (DES): I. The relationship between the DES and other self-report measures of DES
    (Ridgeview Institute and the International Society for the Study of Multiple Personality and Dissociation, 1991-12) Frischholz, Edward J.; Braun, Bennett G.; Sachs, Roberta G.; Schwartz, David R.; Lewis, Jennifer; Shaeffer, Denise; Westergaard, Cindy; Pasquotto, James N.
    The present study attempted to expand the construct validity of the Dissociative Experiences Scale (DES) by comparing it to: (a) other self-report measures of dissociation (e.g., the Tellegen Absorption Scale [TAS] and the Perceptual Alteration Scale [PAS]); (b) the construct of "ambiguity intolerance" (assessed by the Yellen Ambiguity Intolerance Scale [YAIS]); and (c) the Jenkins Activity Schedule (JAS: which measures the degree of Type A behavior). Three hundred and eleven undergraduates participated in an experiment on "Hypnotizability and Personality, " and filled out the DES TAS, PAS, YAIS, and JAS. The DES total score (and three DES factor scores) correlated with the TAS and PAS in the range of .24 - .52 (all correlations were significant at the .001 level, two-tailed). Furthermore, the DES total score (and the three DES factor scores) correlated significantly with the YAIS overall score (r's ranged from .22 - .24, all p's < .001), but did not correlate significantly with the JAS (r's ranged from -.03 - .04, ns). The findings suggest that DES scores (i.e., total scores and each of the three DES factor scores) show good levels of convergent validity as they correlate significantly with other self-report measures of dissociation. However, the intercorrelations were not high enough to consider the different dissociation measures as interchangeable. Furthermore, subjects reporting high levels of dissociative experiences also reported higher levels of ambiguity intolerance. However, no significant association was observed between DES scores and the Type A behavior pattern.
