Cognitive test performance predicts self-reported hearing aid outcome
2015 (English)Conference paper, Poster (Other academic)
In our previous study (Ng et al., 2013), a group of experienced hearing aid users performed a free recall test (Sentence-final Word Identification and Recall test; SWIR). High performers on the test reported more residual difficulty with hearing aids in challenging listening situations. In the present study, we continued to explore relations between recall performance using a modified SWIR test that was less cognitively demanding (Ng et al., 2015) and self-reported hearing aid outcome. The International Outcome Inventory – Hearing Aids (IOI-HA) and the Speech, Spatial and Qualities of Hearing Scale (SSQ) were administered. Results did not reveal any significant correlations between recall performance and self-reported residual difficulty with hearing aids, possibly because the recall performance of low performers on the modified SWIR test was comparable to that of the high performers on the original test. However, in the present study, SWIR performance was positively correlated with both Speech and Qualities domains of the SSQ. In other words, high performers reported better self-assessed speech understanding ability in various real-life situations. No significant correlations were found in the Spatial domain. High SWIR performers also reported less effort in aided listening. These results suggest that better cognitive performance under less demanding listening conditions indexing speech understanding and listening effort is associated with better self-rated aided listening experience. The modified SWIR test, which resembles real-life listening, can potentially be used to assess hearing aid outcome.
