The International Outcome Inventory for Hearing Aids (IOI-HA) is a seven-item questionnaire designed to be generally applicable in evaluating the effectiveness of hearing aid treatments. The inventory was developed to facilitate cooperation among researchers and program evaluators in diverse settings. It is brief and general enough to be appended to other outcome measures that might be planned in a particular application, and will provide directly comparable data across otherwise incompatible projects. For this plan to be successful, it is essential to generate psychometrically equivalent translations in the languages in which hearing aid research and treatment assessments are performed. This article reports the psychometric properties of the inventory for the original English version. The items are reasonably internally consistent, providing adequate statistical support for summing the scores to generate a total outcome score. However, for maximum internal consistency, it would be desirable to generate two scores for the inventory.
助听器国际成效量表（IOI-HA）是一份包含七个条目的问卷，旨在普遍适用于评估助听器治疗的效果。该量表的编制是为了促进不同环境下研究人员和项目评估者之间的合作。它简洁且具有通用性，足以附加到特定应用中可能计划的其他成效测量中，并将在其他不兼容的项目中提供直接可比的数据。为使该计划成功，在进行助听器研究和治疗评估的语言中生成心理测量学等效的翻译至关重要。本文报告了该量表原始英文版本的心理测量学特性。这些条目在内部具有合理的一致性，为将分数相加得出总成效分数提供了充分的统计支持。然而，为了达到最大的内部一致性，最好为该量表生成两个分数。
