| Popis: | Background: Self-report questionnaires are a frequently used method of evaluating hearing aid outcomes. Studies have shown that personality can account for 5–20% of the variance in response to self-report measures. As a result, these influences can impact results and limit their generalizability when the purpose of the study is to examine the technological merit of hearing aids. To reduce personality influences on self-report outcome data, the Device-Oriented Subjective Outcome (DOSO) was developed. The DOSO is meant to demonstrate outcomes of the amplification device relatively independent of the individual’s personality. Still, it is unknown if the DOSO achieves its original goal. Purpose: The purpose of this study was to examine the relationship between personality and the DOSO. The relationship between personality and several widely used hearing-related questionnaires was also examined. Research Design: This is a nonexperimental study using a correlational design. Study Sample: A total of 119 adult hearing aid wearers participated in the study. Data Collection and Analysis: The NEO Five-Factor Inventory was used to measure five personality traits (Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness). The initial (unaided) hearing disablement, residual (aided) hearing disablement, and hearing aid benefit and satisfaction was measured using the DOSO, Hearing Handicap Inventory for the Elderly/Adult, Abbreviated Profile of Hearing Aid Benefit, and Satisfaction with Amplification in Daily Life. The relationship between personality and each questionnaire was examined using a correlation analysis. Results: All of the DOSO subscales were found to be significantly correlated to personality, regardless of whether age and better-ear hearing thresholds were controlled. Individuals who reported poorer hearing aid outcomes tended to have higher Neuroticism scores, while those who scored higher in Extraversion, Openness, and Agreeableness were more likely to report better outcomes. Across DOSO subscales, the maximum variance explained by personality traits ranged from 6% to 11%. Consistent with the literature, ˜3–18% of the variance of other hearing-related questionnaires was attributable to personality. Conclusions: The degree to which personality affects the DOSO is similar to other hearing-related questionnaires. Although the variance accounted for by personality is not large, researchers and clinicians should not assume that the results of the DOSO are independent of personality. |
