To validate the Chinese (Taiwan) version of the Oral Health Impact Profile (OHIP-49T) and develop a short form of the OHIP (OHIP-14T) for the elderly.
A total of 1402 subjects, aged 65 and above, received a personal interview and oral examination. Internal consistency, measured by Cronbach's alpha, and test-retest reliability were assessed by intra-class correlation coefficient (ICC) during a 2-week interval. The criterion-related validity of OHIP-49T was evaluated through associations between the OHIP-49 score with prosthetic need and prosthetic status. A subset (OHIP-14T) questionnaire, derived through a controlled regression procedure, was compared with the original OHIP-14 by Slade (OHIP-14S).
The Cronbach's alpha and ICC values were 0.97 and 0.98 for OHIP-49T and 0.90 and 0.93 for OHIP-14T. Mean scores of the OHIP-49T were significantly associated with prosthetic status (P = 0.0013) and prosthetic need (P = 0.0004), which were examined by dentists. The OHIP-14T score had stronger discriminatory ability than OHIP-14S.
The OHIP-49T showed satisfactory reliability and validity for this Taiwanese elderly population. The OHIP-14T is more effective to measure OHRQoL than OHIP-14S.
验证中文版口腔健康影响量表（OHIP-49T）并为老年人开发 OHIP 的简短形式（OHIP-14T）。
共有 1402 名年龄在 65 岁及以上的受试者接受了个人访谈和口腔检查。在 2 周的间隔内，通过内部一致性（Cronbach's alpha）和测试-重测可靠性（ICC）来评估 OHIP-49T 的内部一致性和测试-重测可靠性。通过 OHIP-49 评分与修复需求和修复状况之间的关联，评估 OHIP-49T 的标准相关效度。通过受控回归过程得到的亚组（OHIP-14T）问卷与 Slade 的原始 OHIP-14（OHIP-14S）进行了比较。
OHIP-49T 的 Cronbach's alpha 和 ICC 值分别为 0.97 和 0.98，OHIP-14T 分别为 0.90 和 0.93。OHIP-49T 的平均得分与牙医检查的修复状况（P = 0.0013）和修复需求（P = 0.0004）显著相关。OHIP-14T 评分比 OHIP-14S 具有更强的区分能力。
OHIP-49T 对台湾老年人群体具有令人满意的可靠性和有效性。OHIP-14T 比 OHIP-14S 更有效地衡量口腔健康相关的生活质量。
