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 this method, the client effectively writes the self-report questionnaire by nominating up to five listening situations in which help with hearing is required. At the conclusion of rehabilitation, reduction in disability and the resulting ability to communicate in these specific situations is quantified. Based on correlation analysis, the COSI method is as statistically valid as the much longer, more traditional questionnaires. Other features, such as relevance, diagnostic utility, compatibility with normal interviewing techniques, and good test-retest reliability, make it particularly suitable for routine clinical use.
通过对98名受试者每人都采用所有方法，比较了几种测量助听器自我报告益处和满意度的方法。许多测量指标之间存在显著相关性，并且对其中两种测量指标进行了两次测量，其重测相关性相当高，这表明大多数测量指标都能有效估计益处和/或满意度。其中一种方法是一种名为“客户导向改进量表”（COSI）的新工具。在这种方法中，客户通过指定多达五种需要听力帮助的聆听情境，有效地编写自我报告问卷。在康复结束时，对这些特定情境下残疾程度的降低以及由此产生的沟通能力进行量化。基于相关性分析，COSI方法在统计学上与长得多且更传统的问卷一样有效。其他特性，如相关性、诊断效用、与正常访谈技巧的兼容性以及良好的重测可靠性，使其特别适合常规临床使用。
