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

Test-retest reliability and criterion validity of an extensively revised version of the feasibility scale for predicting hearing aid use (FSPHAU) was examined. Twenty-two older adults presenting with symmetrical mild to moderate sensory hearing loss completed the revised FSPHAU (pencil and paper) on two occasions prior to hearing aid fitting. The hearing handicap inventory for the elderly was administered during the fitting session and again six months following aid fitting. Test-retest reliability of the revised FSPHAU is not adequate, as revealed by a significant change in the distribution of scores between administrations. From a clinical standpoint, however, true change in an individual's scores was seen in only 4 subjects. In the absence of reliability, discussion of validity becomes moot. The revised FSPHAU cannot supplant trial use of amplification, as client success was not predicted based upon responses offered prior to aid use.
