The Impact of Amplification on Cognitive Screening Test Scores

Hearing loss is associated with cognitive decline in older adults. Research has shown that hearing loss negatively affects cognitive screening test measures as patients may mishear verbally administered questions. The purpose of the current study was to investigate the impact of amplification on performance on a commonly used cognitive screening test. Thirty older adults with hearing loss underwent testing with the Mini-Mental State Examination (MMSE) in three conditions: without hearing aids, with hearing aids, and with a personal listening device (PLD). Performance on the MMSE significantly improved with the use of hearing aids or a PLD. Amplification and the use of communication strategies should be considered when administering cognitive screening measures to older adults. Failure to account for hearing status may lead to invalid results and can increase the likelihood of over-referral for further assessment. [Journal of Gerontological Nursing, 48(7), 31-37.].
