【摘要】：目的研制基于寻常性银屑病患者报告以主症为疗效评价指标的临床结局评价量表(寻常性银屑病主症量表),并评价其信度和效度。方法通过文献研究、专家共识、小组反复讨论制定寻常性银屑病主症量表初版,通过进行现场问卷调查进行信度和效度分析。信度分析主要采用克朗巴赫α系数测量内部一致性信度,并采用探索性因子分析方法考评量表的效度,采用PASI分级为效标评价量表的效标关联度。结果发放213份量表,回收率为99.5%,完成率为98.6%。重测信度Spearman平均相关系数0.88(P0.01),内在一致性分析克朗巴赫α系数为0.86(13个条目)、0.87(14个条目);结构效度分析,13个条目的因子分析共提取了2个公因子,累计因子贡献率为51.28%(KMO=0.87,x±s=914.26,P0.001);14个条目的因子分析共提取了4个公因子,累计因子贡献率为70.42%,(KMO=0.75,x±s=334.06,P0.001);效标关联度分析,13个条目的量表与PASI分为轻中重度分级(PAIS7","7≤PASI≤12","PASI12")评分之间的Spearman相关系数为r=0.26,P0.05。结论构建的寻常性银屑病主症量表有14个条目,且具有良好的信度和效度,这可能成为中医药治疗寻常性银屑病诊疗评价的补充工具。
[Abstract]:Objective to develop and evaluate the reliability and validity of the clinical outcome evaluation scale for psoriasis vulgaris based on the report of patients with psoriasis vulgaris.Methods through the literature research, the expert consensus, the group repeatedly discussed the formulation common psoriasis main illness scale first edition, carries on the field questionnaire survey to carry on the reliability and the validity analysis.The reliability analysis mainly uses the Cronbach 伪 coefficient to measure the reliability of internal consistency, and adopts the exploratory factor analysis method to evaluate the validity of the scale, and uses the PASI classification as the criterion evaluation scale.Results 213 copies were distributed, the recovery rate was 99.5% and the completion rate was 98.6%.The Spearman average correlation coefficient of test-retest reliability was 0.88 (P 0.01), the internal consistency analysis was 0.86 (13 items were 0.87 (14 items)), the structural validity analysis and the factor analysis of 13 items extracted 2 common factors.Conclusion the main psoriasis Vulgaris scale has 14 items and has good reliability and validity, which may be a supplementary tool for the diagnosis and treatment of psoriasis vulgaris.
