title: Validation and cross cultural adaptation of the Italian version of the Harris Hip Score.
abstract: BACKGROUND
  The Harris Hip Score (HHS) is one of the most widely used health related quality of life (HRQOL) measures for the assessment of hip pathology: in spite of this, a validation study, and an official Italian version have not been provided yet. The aim of this study was to create an Italian valid and reliable version of the HHS.
  
  
  METHODS
  The score was translated and modified in Italian; then 103 patients with different hip pathologies were evaluated using this HHS version and also with the WOMAC and the SF-12 questionnaires. Content, construct and criterion validities were tested, such as interobserver reliability, test-retest reliability and internal consistency.
  
  
  RESULTS
  Cross-cultural adaptation was easy, and only minor adaptation was required in the translation process. Construct and criterion validity of the HHS Italian Version were confirmed by satisfactory values of Spearman's Rho for correlation between specific domains of HHS and Womac and SF12 scores. Interobserver and test-retest reliabilities obtained values of 0.996 and 0.975 respectively; Cronbach's alpha for internal consistency was 0.816.
  
  
  CONCLUSIONS
  Statistical and clinical analysis showed that HHS is highly valid and reliable in this new Italian version.
