正畸患者口腔健康素养综合量表的编制及信效度检验

Development and reliability and validity of a comprehensive scale of oral health literacy for orthodontic patients

目的 编制正畸患者口腔健康素养综合评估工具,并对其信效度进行检验。方法 对成人口腔健康素养问卷、牙科畏惧调查量表及改良牙科焦虑量表进行翻译后形成量表初始版,通过7个省的11所三级口腔专科医院的28名专家的2轮函询和预调查,形成正畸患者口腔健康素养综合量表的最终版本,并于2022年9月至12月选取在南京医科大学附属口腔医院接受口腔正畸治疗的362例患者为调查对象,对该量表进行信效度检验。结果 探索性因子分析提取5个公因子,累积方差贡献率为51.293%。验证性因子分析显示χ~2/df=1.509,RMSEA=0.031,CFI=0.948,TLI=0.939,模型适配度良好。最终形成包含阅读理解和知识能力、决策能力、计算能力、倾听能力、心理状态5个维度,共25个条目的量表。结论 正畸患者口腔健康素养综合量表信效度较好,可作为评估正畸患者口腔健康素养综合水平的工具。

Objective To develop a comprehensive oral health literacy assessment tool for orthodontic patients,and to evaluate its reliability and validity.Methods The Comprehensive Oral Health Literacy Adults Questionnaire for Orthodontic Patients(COHL-OAQ) was developed based on the Oral Health Literacy Adults Questionnaire,Dental Fear Survey and Modified Dental Anxiety Scale.Through patient interviews and meticulous item discussion,research team refined and expanded the scale content via two rounds of expert consultation and polit testing.This process culminated in the creation of the COHL-OAQ.From September to December 2022,a total of 362 orthodontic patients from 11 stomatological hospitals in seven provinces was surveyed to assess the reliability and validity of the scale.Results Five common factors were extracted,cumulative variance contribution rate was 51.293%.The confirmatory factor analysis showed that χ~2/df=1.509,RMSEA=0.031,CFI=0.948,TLI=0.939.The final scale consists of 25 items,encompassing fiv dimensions:reading comprehension and knowledge ability,decision-making ability,calculation ability,listening ability,and psychological well-being.Conclusions The COHL-OAQ demonstrates good reliability and validity,making it an appropriate instrument for assessing the comprehensive oral health literacy of orthodontic patients.
