口腔扁平苔藓患者口腔健康相关生活质量的初步研究

目的通过口腔健康影响程度量表（OHIP）-14中文版了解口腔扁平苔藓患者口腔健康相关生活质量情况,探讨其应用于口腔扁平苔藓临床诊疗的可靠性和准确性。方法采用OHIP-14中文版对51例口腔扁平苔藓患者进行问卷调查,同时采用视觉类比标尺（VAS）对疼痛程度进行评分,REU评分系统对病损情况进行评分。通过SPSS 16.0软件对量表的信度和效度进行统计分析。结果OHIP-14的得分为21.67±9.45,量表的内部一致性Cronbach’s α系数为0.901,因子分析提取的5个公因子与量表各领域有密切的逻辑关系,量表得分与REU分值和VAS分值间呈正相关关系（r=0.608,0.807;P<0.000）。结论OHIP-14中文版评测口腔扁平苔藓患者的口腔健康相关生活质量具有较好的信度和效度,可为病情评估提供参考。

Oral health-related quality of life in patients with oral lichen planus

Objective To investigate the oral health-related quality of life in patients with oral lichen planus(OLP) using the Chinese version of the oral health impact profile(OHIP)-14.Methods 51 patients with OLP were included and completed the questionnaire of OHIP-14 subsequently the REU scoring system was utilized to record the local condition and a visual analogue scale(VAS) to rate the pain they experienced.The reliability and validity were analyzed by SPSS 16.0 software.Results The score of OHIP-14 was 21.67±9.45,Cronbach’s alpha of the translated scale was 0.901.The items were divided into 5 domains by factor analysis.There was certain logical relation between the items in the same domain.There was highly significant association between the OHIP-14 score and REU score as well as VAS score(r=0.608,0.807,P<0.000).Conclusion OHIP-14 performs well in patients with OLP,and have good va-lidity and reliability.
