Reliability and validity of the Turkish version of the adolescent dissociative experiences scale

The Adolescent Dissociative Experiences Scale (A-DES) is designed to measure dissociation in adolescents. The present study aimed to assess the reliability, validity, and psychometric characteristics of the Turkish version of the A-DES. The Turkish version of the A-DES was administered to 20 patients with a dissociative disorder, 24 patients with post-traumatic stress disorder (PTSD), 31 patients with anxiety disorder, 31 patients with mood disorder, 24 patients with attention deficit-hyperactivity disorder (ADHD), and 201 non-clinical participants. The internal consistency and the test-retest correlation of the A-DES were excellent. The mean total score of A-DES was 6.2 in dissociative disorder, 3.9 in PTSD, 2.1 in anxiety disorder, 2.4 in mood disorder, 2.5 in ADHD groups and 2.4 in non-clinical participants. There was a statistically significant difference between dissociative patients and other diagnostic groups on the A-DES total score. The good psychometric characteristics of the A-DES among Turkish participants support its cross-cultural validity
