This study aimed to evaluate the reliability and validity of the Chinese version of the Halitosis Associated Life-quality Test (HALT) questionnaire.
A total of 106 patients with oral malodour were recruited to complete the questionnaire after its translation and cross-cultural adaptation. The reliability of the Chinese version of the HALT was evaluated using internal consistency and test-retest methods. Both construct validity and discriminative validity were adopted to evaluate the validity of the HALT.
The Cronbach's alpha value (internal reliability) for the total HALT score was 0.95, and the intraclass correlation coefficient (ICC) value (test-retest reliability) was 0.89 (95% CI = 0.74-0.98). The construct validity was determined by exploratory factor analysis. Four factors were extracted, which accounted for 85.18% of the variance. All items had factor loadings above 0.40, ranging from 0.53 to 0.94. In addition, the Chinese version of the HALT was found to be valid for distinguishing patients with different degrees of oral malodour.
The results suggest that the Chinese version of the HALT has satisfactory psychometric properties and is applicable to patients with oral malodour in Chinese-speaking populations.
本研究旨在评估口臭相关生活质量测试（HALT）问卷中文版的信度和效度。
共招募了 106 名口臭患者，在对问卷进行翻译和跨文化调适后，让他们完成问卷。采用内部一致性和重测信度评估中文版 HALT 的信度。采用结构效度和判别效度来评估 HALT 的效度。
HALT 总分的克朗巴赫α值（内部信度）为 0.95，组内相关系数（ICC）值（重测信度）为 0.89（95%置信区间=0.74-0.98）。结构效度通过探索性因子分析确定。提取了 4 个因子，占方差的 85.18%。所有项目的因子负荷均高于 0.40，范围为 0.53 至 0.94。此外，中文版 HALT 可有效区分不同口臭程度的患者。
结果表明，中文版 HALT 具有良好的心理测量特性，适用于讲中文的口臭患者。
