title: [Analysis of reliability of the Chinese version of satisfaction with amplification in daily life].
abstract: OBJECTIVE
  To investigate the reliability of the Chinese version of Satisfaction with Amplification in Daily Life (SADL).
  
  
  METHODS
  The cross-cultural adaption measures were used to translate the SADL into Chinese version. Thirty hearing aid users no younger than 18 years old were included. Test-retest analysis was administrated to the patients without significant changes in health and social status with an interval of two weeks between test and retest.
  
  
  RESULTS
  Test-retest reliability of the SADL was proved to be satisfactory. All subscales and global score had coefficients that exceeded 0.70 (P < 0.01). Except for "personal image", the score of other subscales and global score in this study are higher than the U. S. interim norms described by Cox and Alexander (1999) (P < 0.01).
  
  
  CONCLUSIONS
  This study completed the translation and test-retest analysis of Chinese version of SADL. We need further discussion about validation of Chinese version of SADL in order to meet basic psychometric criteria of a standard outcome measurement.
