牙周炎患者口腔健康素养量表的修订及信效度评价

Oral Health Literacy Adults Questionnaire for periodontitis patients:revision and evaluation of reliability and validity

目的修订适用于牙周炎患者的口腔健康素养评估工具,并评价其信效度。方法对成人口腔健康素养量表进行跨文化调适,通过患者访谈和专家会议对量表条目进行筛选和补充,通过Delphi专家咨询和预调查对量表条目进行修订完善,形成中文版牙周炎患者口腔健康素养量表。选取北京市某三甲口腔医院牙周炎患者720例进行调查,对量表进行信效度评价。结果探索性因子分析提取4个公因子,累积方差贡献率为46.116%。验证性因子分析结果χ^(2)/df=1.514,RMSEA=0.032,CFI=0.950,TLI=0.943,模型适配良好。最终形成的量表包括阅读理解和知识能力、决策能力、计算能力、倾听能力4个维度,共21个条目。量表总体Cronbach′s α系数为0.833,折半信度为0.847。量表条目水平的内容效度指数为0.800~1.000,量表水平的内容效度指数为0.970。结论中文版牙周炎患者口腔健康素养量表具有良好的信效度,可作为临床和科研评价牙周炎患者口腔健康素养水平的可靠工具。

Objective To revise a tool for oral health literacy assessment of periodontitis patients,and to evaluate its reliability and validity.Methods The Oral Health Literacy Adults Questionnaire(OHL-AQ)was cross-culturally adapted,and the questionnaire items were screened and supplemented through patients interview and experts meeting,then a Delphi study and a pre-test survey were conducted to revise and perfect the items,finally a Chinese version of Oral Health Literacy Adults Questionnaire for periodontitis patients(OHL-PAQ)was formed,which was utilized to investigate 720 periodontitis patients from a tertiary dental hospital in Beijing to analyze its reliability and validity.Results Totally 4 common factors were extracted via exploratory factor analysis,whose cumulative variance contribution rate was 46.116%.Confirmatory factor analysis resulted in χ^(2)/df=1.514,RMSEA=0.032,CFI=0.950,and TLI=0.943,indicating that the model fitted well.The final OHL-PAQ included four dimensions,namely reading comprehension and knowledge ability,decision-making ability,computing ability and active listening ability,which consisted of 21 items.The Cronbach′s α coefficient of the questionnaire was 0.833,its split-half reliability was 0.847.The I-CVI of each item ranged from 0.800 to 1.000,and the S-CVI of the scale was 0.970.Conclusion The Chinese version OHL-PAQ has good reliability and validity,it can be used as a reliable tool for clinical and scientific evaluation of oral health literacy level in periodontitis patients.
