ABS TRACT Objective:This study aims to determine the prominent factor of hearing aid (HA) satisfaction in individuals using HAs by examining the effects of audiologic factors and self-esteem on HA satisfaction, and to create evidence-based data for counseling and rehabilitation services related to HA. Material and Methods: Eighty six individuals using bilateral HA aged from 55-80 (71.37±7.95) years participated.Word Recognition Scores (WRS), Random Gap Detection Test (RGDT), Rosenberg Self-Esteem Scale, and the Turkish version of International Outcome Inventory for Hearing Aids (IOI-HA-TR) were used as assessment tools.Linear regression and correlation analysis were used to determine the amount of variance explained by effective factors in HA satisfaction.Results: There was a significant positive and low-level relationship between the level of satisfaction with the HA (IOI-HA-TR) and the Rosenberg Self-Esteem Scale Score (Spearman correlation analysis; r=0.393, p<0.001).There was no significant relationship between the level of satisfaction with the HA (IOI-HA-TR) and the audiological factors evaluated in the study (RGDT and WRS) (Spearman correlation analysis, p>0.05).While self-esteem explains 26.2% of the variation in satisfaction (R²=0.262)(linear regression analysis; p<0.01), the ability to process temporal features of the sound (RGDT) explains 6.9% (R²=0.069)(linear regression analysis; p<0.05).Conclusion: This study emphasizes that the self-esteem of individuals is a prominent factor in satisfaction with hearing aids, and the importance of enriching audiological rehabilitation with multidisciplinary practices.
