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.
对一个经过大幅修订的预测助听器使用可行性量表（FSPHAU）的重测信度和效标效度进行了检验。22名患有对称性轻度至中度感音神经性听力损失的老年人在助听器验配前两次完成了修订后的FSPHAU（纸笔形式）。在验配期间以及验配后六个月再次进行了老年人听力障碍问卷的评估。两次施测之间分数分布发生了显著变化，这表明修订后的FSPHAU重测信度不足。然而，从临床角度来看，只有4名受试者的分数出现了真正的变化。在缺乏信度的情况下，效度的讨论就变得没有意义了。修订后的FSPHAU无法取代放大装置的试用，因为根据使用助听器之前提供的回答并不能预测客户的使用成功情况。
