In an undergraduate sample (N = 214), we examined the construct validity of the Clinician Administered Dissociative States Scales (CADSS; Bremner, Krystal, Putnam, Southwick, Marmar, Charney, et al., 1998) in the context of measures of state and trait dissociation, administered in conjunction with measures of depression, state anxiety, and affect. We found evidence for the convergent and discriminant validity of the dissociation measures in terms of correlations among dissociation measures that exceeded the correlations of the dissociation measures with measures of other constructs. Internal consistencies of the dissociation measures exceeded .80. Multiple regression analyses provided further evidence of construct validity in that variance in dissociation scores was largely accounted for by scores on other dissociation measures. Nevertheless, measures of anxiety, affect, and depression accounted for incremental variance in the prediction of dissociation measures and therefore should be included in a comprehensive model of dissociation. Our results strongly support the construct validity of the measures of dissociation.
