Several methods for measuring the self-reported benefit and satisfaction provided by a hearing aid were compared by administering all methods to each of 98 subjects. Significant correlations between many of the measures and reasonably high test-retest correlations for two of the measures administered twice suggest that most of the measures provide valid estimates of benefit and/or satisfaction. One of the methods included is a new tool called the Client Oriented Scale of Improvement (COSI). In…

Measuring the Outcomes of a National Rehabilitation Program: Normative Data for the Client Oriented Scale of Improvement (COSI) and the Hearing Aid User’s Questionnaire (HAUQ)

Self-report outcome measures appear to be most suitable for identifying needs, identifying individuals receiving markedly less than average benefit, and for finding small differences between outcomes for subgroups of the population.

Evaluation of Auditory Functioning and Rehabilitation Using Patient-Reported Outcome Measures

The effects of hearing loss were more salient in AVAB, while both AVAB and COSI showed differences regarding hearing aid experience, suggesting that both methods should be used in a complementary manner, rather than separately.

Development of the Communication and Acceptance Scale (CAS) for group aural rehabilitation

The CAS questionnaire was found to be valid and reliable, but because of the low sample size, further analysis with a larger population is needed.

An Investigation of the Applicability of the Inventory, Satisfaction with Amplification in Daily Life, at 2 Weeks Post Hearing Aid Fitting

2 wk postfitting is too early for meaningful application of the SADL as an outcome measure, and it is suggested that the long-term value of self-report methods will depend on development of rigorous and scientifically acceptable administration procedures, including appropriate times for application.

The Use of Outcome Measures to Formulate Intervention Strategies

Although the open‐set Problem Questionnaire approach is valid in the domain of Activity Limitation, it needs to be supplemented by an additional measure of Participation Restriction, either open‐ set or structured, to ensure optimal patient management.

Hearing Aid Satisfaction: What Does Research from the Past 20 Years Say?

It is hoped that this review will help readers understand current satisfaction measures, how various factors affect satisfaction, and how the way satisfaction is measured may be improved to yield more reliable and valid data.

Self-Report Outcome Measures for Adult Hearing Aid Services: Some Uses, Users, and Options

Self-report measures of disability and handicap, and hence the benefits of intervention, now constitute an unassailable element in the authors' understanding of the consequences of impaired hearing and essential components for the evaluation and optimization of interventions designed to alleviate those deficits.

Study probes impact on hearing aid benefit of earlier involvement by significant other

The purpose of this study was to determine if the APHAB would reveal any differences in perception of hearing aid benefit when the SO was included in initial discussions on hearing aid candidacy.

Development of the Three-Clinic Hearing Aid Selection Profile (HASP).

The results of the first investigation suggest that the development of a 40-item metric with adequate internal consistency reliability that assesses a patient's beliefs about a number of basic considerations felt to be critical to the hearing aid selection (HAS) process is successful.



The Hearing Handicap Inventory for the Elderly: a New Tool

The reliability and validity of the HHIE as well as its brevity, simplicity, and ease of administration and interpretation all recommend its use in assessing hearing handicap in the elderly.

Self-report approach to assessing benefit derived from amplification.

A self-report methodology for measuring successful use of amplification in daily life appears promising as a criterion measure in predictive validation studies of hearing aid selection procedures.

Comparison of two questionnaires for patient-assessed hearing aid benefit.

Two questionnaires, the Profile of Hearing Aid Benefit (PHAB) and the intelligibility Rating Improvement Scale (IRIS), were developed to measure self-assessed hearing aid benefit and the potential of each questionnaire was evaluated for clinical and research applications.

The Abbreviated Profile of Hearing Aid Benefit

A shortened version of the Profile of hearing aid benefit, to be called the Abbreviated Profile of Hearing Aid Benefit, or APHAB, which uses a subset of 24 of the 66 items from the PHAB, scored in four 6-item sub-scales is developed.

Shortcomings of a revised feasibility scale for predicting hearing aid use with older adults.

The revised FSPHAU cannot supplant trial use of amplification, as client success was not predicted based upon responses offered prior to aid use and in the absence of reliability, discussion of validity becomes moot.

Predictability and reliability of hearing aid benefit measured using the PHAB.

It is concluded that the PHAB is best suited for group research: when used for individual subjects, thePHAB may not be sensitive enough to detect important differences between hearing aid conditions.

Quality-of-life changes and hearing impairment. A randomized trial.

Hearing loss is associated with important adverse effects on the quality of life of elderly persons, effects which are reversible with hearing aids.

The Hearing Handicap Inventory for the Elderly as a measure of hearing aid benefit.

A significant reduction in the perceived emotional and social effects of hearing impairment following 1 year of hearing aid use was revealed, and the reduction in perceived handicap was greater for the hearing aid users than for their spouses.

Self‐perceived and Audiometric Evaluations of Hearing Aid Benefit in the Elderly

Results indicated a significant decrease in perceived handicap after 3 wk of hearing aid use, and benefit as defined using functional gain data was unrelated to benefit asdefined using self-report data.

Sustained benefits of hearing aids.

It is concluded that hearing aids provide sustained benefits for at least a year in these elderly individuals with hearing impairment.
