Trial Outcomes & Findings for Administration Method of Cognitive Screening in Older Individuals With Hearing Loss (NCT NCT03402932)

NCT ID: NCT03402932

Last Updated: 2019-04-03

Results Overview

The cognitive screening test of Montreal Cognitive Assessment (MoCA) was administered to 4 groups with different administration method conditions (see arms/groups table). MoCA is s standardized cognitive screening tool for mild cognitive impairment and dementia. The total score was used as outcome measure of this study and this score ranges from 0-30, with higher score being better performance.

Recruitment status

Measure
Group1: Auditory -Visual (Younger Adults w/ Normal Hearing)
A group of younger adults with normal hearing is included to validate the visual version of the tests
Group2: Amplified-Visual (Older Adults w/ Hearing Loss)
Auditory amplified: The cognitive test was administered using a computer-based signal processing to amplify the instruction. The presentation level was customized to the individual's hearing thresholds. Visual: The cognitive test was administered visually by using timed computer slides.
Group3: Amplified-Unamplified (Older Adults w/ Hearing Loss)
Auditory amplified: The cognitive test was administered using a computer-based signal processing to amplify the instruction. The presentation level was customized to the individual's hearing thresholds. Auditory unamplified: The cognitive test was administered by using a generic presentation level that simulates a normal conversational level.
Group4: Visual-Unamplified (Older Adults w/ Hearing Loss)
Visual: The cognitive test was administered visually by using timed computer slides. Auditory unamplified: The cognitive test was administered by using a generic presentation level that simulates a normal conversational level.
