Abstract
PURPOSE: The aims of the study were to compare the Cognitive Self-Report Questionnaire (CSRQ; Spina, Ruff, & Mahncke, 2006) Hearing and Cognitive subscale ratings among older adults with and without probable mild cognitive impairment (MCI) and to examine whether self-report, as measured by the CSRQ, is associated with objective measures of hearing, auditory processing, and cognition.
METHOD: Data analyses included 97 older adults of ages 61-91 years. Participants completed the CSRQ self-report measure as well as a battery of objective measures, including pure-tone audiometry, degraded speech understanding, temporal processing, and memory.
RESULTS: Older adults with probable MCI rated their cognitive abilities more poorly than those without MCI (p = .002), but ratings of hearing and auditory abilities did not differ between the two groups (p = .912). Age and CSRQ Hearing subscale ratings explained a significant proportion of variance in objective measures of hearing and degraded speech understanding (R2 = .39, p < .001). Age, sex, mental status, and CSRQ Cognition subscale ratings explained a significant proportion of variance in objective memory performance (R2 = .55, p < .001).
CONCLUSIONS: Taken together, these results suggest that the CSRQ is an appropriate self-report measure of hearing, cognition, and some aspects of auditory processing for older adults with and without probable MCI.
