Jang, Yuri, James A Mortimer, William E Haley, Theresa E Hnath Chisolm, and Amy Borenstein Graves. (2002) 2002. “Nonauditory Determinants of Self-Perceived Hearing Problems Among Older Adults: The Role of Stressful Life Conditions, Neuroticism, and Social Resources.”. The Journals of Gerontology. Series A, Biological Sciences and Medical Sciences 57 (7): M466-9.

BACKGROUND: The present study explored factors that influenced older individuals' subjective perception of hearing problems. In addition to objectively screened hearing ability, nonauditory factors such as stressful life conditions (visual impairment, chronic disease, disability, and recent stressful life events), neuroticism, and social resources were hypothesized to be predictors of self-perceived hearing problems.

METHODS: These hypotheses were tested with a hierarchical regression model using a stratified sample of 425 community-dwelling older individuals (mean age = 72.2).

RESULTS: Individuals with more recent stressful life events, higher levels of neuroticism, and less emotional support reported greater hearing problems after controlling for objectively screened hearing. In addition to the main effects, a significant interaction was observed between neuroticism and screened hearing, indicating that the combination of poor hearing and high neuroticism increased the level of self-perceived hearing problems.

CONCLUSIONS: The findings suggest that the effects of nonauditory factors should be taken into account in the application of self-assessed measures of hearing problems.

Abrams, Harvey, Theresa Hnath Chisolm, and Rachel McArdle. (2002) 2002. “A Cost-Utility Analysis of Adult Group Audiologic Rehabilitation: Are the Benefits Worth the Cost?”. Journal of Rehabilitation Research and Development 39 (5): 549-58.

The purpose of this study was to conduct a cost-utility analysis comparing two treatment approaches: (1) hearing aid use alone (HA) and (2) hearing aid use with short-term group postfitting audiologic rehabilitation (HA + AR). A total of 105 veterans, 67 males and 38 females, with at least a mild sensorineural hearing loss participated in this study. The SF-36V was administered to each participant before and after treatment. This instrument measures both mental component summary (MCS) scales and physical component summary (PCS) scales of quality of life. As a whole, the participants exhibited a statistically significant improvement in mean MCS scores pre- to postintervention, with average improvements of 1.4 and 3.0 points for the HA and HA + AR groups, respectively. With the use of the MCS scores, the results of a cost-utility analysis revealed that HA treatment cost $60.00 per quality-adjusted life year (QALY) gained, while HA + AR cost only $31.91 per QALY gained, making HA + AR the more cost-effective treatment.
