For evaluation of audiological service outcomes, the primary objective was to determine baseline and target profiles on the Speech, Spatial, and Qualities of Hearing Scale (SSQ); a secondary objective was to test a short form of the SSQ; opportunity was also taken to compare responses of samples providing consistent versus inconsistent self-assessments.
2 × 2 × 2 factorial design crossed age, reported presence versus absence of hearing difficulty, and low versus high self-rated hearing ability.
Eight samples (total, n = 413), representing two age ranges; a response of "yes" or "no" to a question about having hearing difficulty, and either low or high self-rated hearing ability on six items from the SSQ.
Using present and previous results, baseline SSQ profiles were determined indicating the pattern of response likely to be observed prior to clinical intervention, and both an achieved outcome and "ideal" target outcome from such intervention. The six-item SSQ yielded better test-retest results in consistent versus inconsistent samples. The inconsistent samples showed signs of different interpretations of "hearing difficulty".
Baseline, and both actual and ideal target outcomes can guide comparative appraisal of clinical achievements; more research is needed to determine a robust short form of the SSQ.
为了评估听力学服务的结果，主要目标是确定言语、空间和听觉质量量表（SSQ）的基线和目标特征；次要目标是测试 SSQ 的简短形式；同时还有机会比较提供一致和不一致自我评估的样本的反应。
2×2×2 析因设计，交叉年龄、报告存在或不存在听力困难以及自我评估听力能力的高低。
8 个样本（总共 n=413），代表两个年龄范围；对是否有听力困难的问题回答“是”或“否”，以及 SSQ 的六个项目中自我评估听力能力的高低。
使用现有和以前的结果，确定了 SSQ 的基线特征，表明了在临床干预之前可能观察到的反应模式，以及这种干预的实际结果和“理想”目标结果。六项目 SSQ 在一致和不一致的样本中产生了更好的测试-重测结果。不一致的样本显示出对“听力困难”不同解释的迹象。
基线以及实际和理想的目标结果可以指导对临床成果的比较评估；需要进一步研究以确定 SSQ 的可靠简短形式。
