SADL
Pronunciation: sad-el
Also written as: SADL — Satisfaction with Amplification in Daily Life
Acronym for the Satisfaction with Amplification in Daily Life scale, a validated self-report tool measuring patient satisfaction with hearing aid use across four subscales.
Full Definition
The Satisfaction with Amplification in Daily Life (SADL) scale is a 15-item, self-administered questionnaire that measures hearing aid wearer satisfaction across four subscales: positive effects, service and cost, negative features, and personal image. It was developed by Cox and Alexander and is commonly used in adult aural rehabilitation research and clinical audit. Editors working on audiology manuscripts must verify that SADL subscale names are capitalised consistently and that the four subscales are not incorrectly collapsed into a single score. SADL is distinct from the GHABP, which additionally captures hearing aid benefit and use frequency.
Usage
Usage note: Define on first use. Confirm subscale names are capitalised as in the original instrument. Do not report a composite SADL score without citing a validated method for doing so.
