To determine whether hearing aid outcome measured by the Hearing Handicap Inventory (HHI) for the Elderly/Adults (Newman, Weinstein, Jacobson, & Hug, 1990; Ventry & Weinstein, 1982) is differentially affected by informed vs. blind administration of the postfitting questionnaire.
Participants completed the HHI at their hearing aid evaluation and again at their hearing aid follow-up visit. At follow-up, half received a clean HHI form (blind administration), whereas the remainder responded on their original form (informed administration) and could thus base their follow-up responses on those they gave at the hearing aid evaluation.
The data show that for the population examined here, informed administration of the follow-up HHI did not yield a different outcome to blind administration of the follow-up HHI. This was not influenced by past hearing aid use, age of the participant, or the duration of time between baseline questionnaire completion and follow-up completion.
These data suggest that completion of follow-up questionnaires in either informed or blind format will have little impact on HHI responses, most likely because of the many other factors that combined to influence hearing aid outcome.
确定通过老年人/成年人听力障碍量表（HHI）（纽曼、温斯坦、雅各布森和胡格，1990年；文特里和温斯坦，1982年）测量的助听器效果是否会因在佩戴后问卷的填写过程中是否知晓前期信息而受到不同影响。
参与者在助听器评估时完成HHI量表填写，并在助听器随访时再次填写。在随访时，一半参与者收到一份空白的HHI表格（不知情填写），而其余参与者则在他们原来填写的表格上作答（知情填写），因此他们的随访回答可以基于他们在助听器评估时给出的回答。
数据表明，对于此处所研究的人群，随访HHI量表的知情填写与不知情填写所产生的结果并无差异。这不受过去使用助听器的情况、参与者年龄或基线问卷完成与随访完成之间的时间长短的影响。
这些数据表明，以知情或不知情的方式完成随访问卷对HHI量表的回答影响很小，这很可能是因为还有许多其他因素共同影响着助听器的效果。
