Vanderlinden and his collegues (1993) proposed a first european clinical scale to assess dissociative symptoms, the DIS-Q. The DIS-Q was studied in a psychiatric (n = 154) and a control (n = 65) Swiss French speaking sample. Our results reflected that The Dissociation Questionnaire (DIS-Q) has a good criterion-related validity since it discriminates between patients (Axes I and II of the DSM IV classification) and controls. Statistical comparisons indicated significant differences between three subgroups (axis I only, n = 60; axis II only, n = 24; axes I et II together, n = 70), and controls (n = 65). The total DIS-Q score was the highest for the patients with axes I and II together. About 12 % of the psychiatric sample studied obtained DIS-Q score greater than or equal to 2.5, suggesting the presence of pathological dissociative symptoms. Our results seem not to be influenced by cultural factors.
