title: [Evaluation of the psychometric properties of the Spanish version of 5 questionnaires for the evaluation of post-traumatic stress syndrome].
abstract: OBJECTIVE
  To determine the psychometric properties of the Spanish versions of the following scales for assessing PTSD patients: TQ, CAPS-DX, DTS, TOP-8, and DGRP.
  
  
  METHODS
  Data from 63 PTSD patients and 23 healthy subjects were analysed. Internal consistency and test-retest reliability (after 15 days) were calculated. Convergent validity was analysed by correlating subjects' scores with the number of symptoms (DSM-IV) and scores on the CGI scale. Discriminative capability was analysed by comparing TQ, CAPS-DX, DTS, TOP-8, and DGRP patients' scores with scores from healthy subjects, and between patients' subgroups according to the presence or absence of psychiatric comorbidity and to the degree of severity as determined by the CGI-S.
  
  
  RESULTS
  CAPS-DX, DTS, TOP-8, and DGRP showed an adequate internal consistency (Cronbach alpha: 0.74-0.91) and all of them obtained ICC between 0.77 and 0.93. The five questionnaires were able to discriminate between patients and healty subjects, and between the patients' subgroups.
  
  
  CONCLUSIONS
  The Spanish versions of the TQ, CAPS-DX, DTS, TOP-8, and DGRP have shown adequate reliability and validity for assessing PTSD patients in daily clinical practice. CAPS-DX seems to be more adequate a diagnostic and DTS a severity rating scale.
