Effect of Age on the Score of the Persian Version of the University of Cincinnati Auditory Processing Inventory: A Pilot Study

Background and Aim: The Persian version of the University of Cincinnati Auditory Processing Inventory (P-UCAPI) is used to evaluate auditory processing disorders in Iranian people using six subscales, each focusing on different auditory skills. In this study, we aimed to compare the total score and the subscale scores of the P-UCAPI among three age groups to evaluate the impact of aging on auditory processing. Methods: Participants in three age groups of 20, including 21–39 years (group A), 42–60 years (group B), and 61–80 years (group C) completed the P-UCAPI. One-way ANOVA and Welch’s t-test was used to compare the mean scores of each subscale among the three groups. Results: The mean scores of listening and concentrating (p<0.001), understanding speech (p<0.001), attention (p=0.010), and other (p<0.001) were significantly lower in group       C compared to group A. The mean scores of listening and concentrating (p=0.001), understanding speech (p<0.001), and other (p<0.001) were significantly lower in group C compared to group B. The mean total score was not significantly different between groups A and B (p=0.333). However, the difference was significant between groups A and C (p<0.001) and between groups B and C (p<0.001). Conclusion: The increase of age affects the auditory processing and generally reduces the auditory performance. Keywords: Age; auditory processing disorders; inventory; Persian
