title: Validation of the Italian version of the Screening Questionnaire for Disaster Mental Health (SQD) in a post-earthquake urban environment.
abstract: BACKGROUND
  Aim of this study was to implement and validate the Italian version of the Screening Questionnaire for Disaster Mental Health (SQD), a tool for the screening of post-traumatic stress disorder (PTSD) and depression in the long-term aftermaths of a natural disaster.
  
  
  METHODS
  A convenience sample of 116 subjects living in L'Aquila after the 2009 earthquake were administered the SQD and two gold-standard instruments for PTSD and depression. Reliability, concurrent validity and convergent validity of SQD were estimated.
  
  
  RESULTS
  Cronbach's alpha was 0.86. Concurrent validity as measured by the Spearman correlation coefficient resulted statistically significant both for PTSD and depression SQD subscales, as well as convergent validity as measured by ROC-AUC method.
  
  
  CONCLUSIONS
  SQD is a valid, efficient and easy-to-use screening instrument for PTSD and depression after natural disasters.
