title: [The cross-cultural adaptation to Portuguese of the Dissociative Experiences Scale for screening and quantifying dissociative phenomena].
abstract: OBJECTIVE
  This paper presents the cross-cultural adaptation to Portuguese of the Dissociative Experiences Scale, the worldwide most employed questionnaire for screening and quantifying dissociative phenomena.
  
  
  METHODS
  Two translations and their respective back-translations were performed, as well as the evaluation of the semantic equivalence, the preparation of the synthetic version, the pre-testing on the target population, the definition of the final version and a second pre-testing on the target population.
  
  
  RESULTS
  A high level of semantic equivalence between the original instrument and the two pairs of translations and back-translations was observed regarding the referential and general meanings. The two pre-testing in the target population led to alterations in order to achieve the semantic and operational equivalence criteria.
  
  
  CONCLUSIONS
  This work provides the first adaptation of a specific instrument to detect and quantify dissociative symptoms in the Brazilian context.
