Abstract This study aimed to assess the reliability, validity, and psychometric characteristics of the Turkish version of the Somatoform Dissociation Questionnaire (SDQ-20). In this context, it investigated whether somatoform dissociation differentiates dissociative disorders from other diagnostic groups and non-clinical individuals. The Turkish Version of the SDQ-20 was administered to 50 patients with a dissociative disorder, 94 patients with psychiatric disorders other than dissociative disorder, and 175 non-clinical participants. To confirm the clinical diagnosis, all patients in the dissociative disorder group had been evaluated using the Structured Clinical Interview for DSM-IV Dissociative Disorders. The internal consistency and the test-retest correlation of the SDQ-20 were excellent. The scale had strong correlations with the DES and the DIS-Q. There was a statistically significant difference between dissociative patients and other diagnostic groups on the SDQ-20 total score. The discriminative power of the SDQ-20 was as robust as that of the DES. There was no significant difference between the mean SDQ-20 total scores of Turkish and Dutch patients, but Turkish dissociative patients reported pseudoseizures more frequently than Dutch patients. The specificity of the short version of the scale (SDQ-5) was weak among Turkish patients. Dissociative disorders can be differentiated from other diagnostic groups through somatoform dissociation. The good psychometric characteristics of the SDQ-20 among Turkish participants support its cross-cultural validity.
