title: Clinical application of the satisfaction with amplification in daily life scale in private practice I: statistical, content, and factorial validity.
abstract: Statistical, content, and factorial validity of the Satisfaction with Amplification in Daily Life (SADL) scale was assessed. SADL subscales closely correspond to four satisfaction domains. Subjective benefit is a key component of satisfaction, but other nonauditory factors contribute to wearer satisfaction, notably telephone use and appearance. Results confirm the SADLs psychometric properties and verify its use to validate hearing aid fitting satisfaction in private practice settings for a general patient population at 1-year postfitting. Interim SADL norms may be refined as more SADL data are obtained for different patient populations, hearing aid types, and fitting environments.
