CHARACTERIZATION: self-response instrument based on DSM dissociation characterization with the objective of evaluating dissociative experiences in adolescents. STRUCTURE AND SCORING: 11 items answered through a Likert scale from 0 (never) to 10 (always). The total score derives from the sum of the scores of all items divided by the number of items, ranging from 0 to 10 (high dissociation). PSICOMETRIC CHARACTERISTICS: The internal consistency measured by Cronbach’s Alpha model showed a value of 0.94. The factorial analysis of the scale structure revealed a solution of one factor that explained 38.8% of the variance. The A-DES discriminated between adolescents with mental health problems (M ± SD = 3.89 ± 1.84) and healthy adolescents (M ± SD = 2.06 ± 1.41). CUTOFF SCORE: Receiver Operating Curve confirmed the value 4 determined in other studies.
