title: Validation of the Chinese version "satisfaction with amplification in daily life (SADL)" survey for hearing-aid users.
abstract: OBJECTIVE
  Satisfaction with amplification in daily life (SADL) may quantify satisfaction with hearing aids. We translated and validated a Chinese version of SADL (CSADL).
  
  
  METHODS
  The SADL was translated from English to Mandarin Chinese by two bilingual physicians. The CSADL was administered to hearing-aid users and tested for reliability and validity.
  
  
  METHODS
  There were 155 hearing-aid users who completed the CSADL prospectively, and 39 subjects were retested after 4 to 6 weeks for test-retest reliability.
  
  
  RESULTS
  The CSADL had good internal consistency (Cronbach α = 0.63 to 0.92), within survey reliability (r = 0.54 to 0.69; P ≤ .05), and test-retest reliability (r = 0.93 to 0.98; P ≤ .05). The CSADL dimensions correlated well with worse-ear speech discrimination score (P ≤ .05). The CSADL global score significantly correlated with the general health (r = 0.236; P ≤ .05), vitality (r = 0.162; P ≤ .05), social functioning (r = 0.190; P ≤ .05), and mental health (r = 0.224; P ≤ .05) subscales of the Mandarin Chinese Taiwan version of the medical outcome 36-item short-form health survey.
  
  
  CONCLUSIONS
  The CSADL is a valid and reliable questionnaire to evaluate satisfaction among Chinese hearing-aid users.
