Abstract:
Objective:To investigate the reliability and validity of the Chinese version of the Satisfaction with Amplification in Daily Life (SADL).Method:Ninety adult hearing aid users were evaluated with Chinese version of the SADL.Result:①Reliability:Cronbach's α score of overall SADL score was 0.814 and the four subdomains were 0.543-0.824. ②Validity: The correlation coefficients between overall SADL score and the four subdomains were 0.514-0.826(all P<0.01).There were weak or no correlations among the four subdomains. The evaluation of content validity by expertreview showed the questionnaire had good content validity. SADL total scores in bilateral hearing aid userswere significantly higher than those in unilateral hearing aid users (t=2.192,P<0.05).Conclusion:The Chinese version of the SADL meets many psychometric criteria of a robust instrument. It possesses appropriate validity and good reliability, and can be used to measure the outcome for adult hearing aid users in China.
