This study aimed to translate the Oral Health Literacy Adult Questionnaire into a Mandarin version (MOHL-AQ) and to examine its psychometric properties.
A methodological research using psychometric testing and evaluation of a translated instrument. A convenience sample of 402 participants from northern Taiwan were recruited for the validation of the MOHL-AQ. Internal consistency reliability, split-half reliability, inter-rater reliability, face validity, content validity, and construct validity were evaluated.
The value of internal consistency and split-half reliability of the MOHL-AQ were 0.77 and 0.78, respectively. Content validity reported a high content validity index (CVI = 95%). Exploratory factor analysis (EFA) and parallel analysis (PA) were used to determine a unidimensional model and confirmatory factor analysis (CFA) was employed to confirm the model. The indices of good fit model were achieved at GFI = 0.93, AGFI = 0.92, RMSEA = 0.04, CFI = 0.90, PGFI = 0.73, χ /df = 1.86 (p < .001). Most of the item-total correlations indicated adequate and acceptable convergent validity (r > .30).
MOHL-AQ demonstrates adequate psychometric properties for measuring the oral health literacy in Mandarin-speaking population. Public health nurses can use MOHL-AQ to assess oral health literacy in the community settings and further screen potential population with inadequate oral health literacy.
本研究旨在将《口腔健康素养成人问卷》（Oral Health Literacy Adult Questionnaire）译为简体中文版本（MOHL-AQ），并检验其心理测量学特性。
采用心理测试法和翻译后评估的方法进行方法学研究。本研究在台湾北部地区采用便利抽样法招募了 402 名参与者，以验证 MOHL-AQ 的有效性。评估内容包括内部一致性信度、半分信度、评分者间信度、表面效度、内容效度和结构效度。
MOHL-AQ 的内部一致性和半分信度值分别为 0.77 和 0.78。内容效度的内容效度指数（CVI）为 0.95%，表明内容效度较高。探索性因子分析（EFA）和并行分析（PA）用于确定单维模型，验证性因子分析（CFA）用于确认模型。良好拟合模型的指标在以下方面得到了实现：GFI=0.93，AGFI=0.92，RMSEA=0.04，CFI=0.90，PGFI=0.73，χ/df=1.86（p<0.001）。大多数项目总分相关性表明具有足够且可接受的聚合效度（r>0.30）。
MOHL-AQ 具有足够的心理测量学特性，可用于测量普通话人群的口腔健康素养。公共卫生护士可以使用 MOHL-AQ 在社区环境中评估口腔健康素养，并进一步筛选出口腔健康素养不足的潜在人群。
