卒中危险因素初筛表的信度及效度研究

目的 检验卒中危险因素初筛表的信度、效度。 方法 对130例测试对象进行卒中危险因素初筛表、改良弗明汉卒中风险评估量表（Framingham Stroke Profile，FSP）进行调查，检验卒中危险因素初筛表的信度及效度。 结果 卒中危险因素初筛表的Cronbach α系数为0.701，分半信度为0.826，重测信度为0.94。因子分 析法提取5个共性因子，公因子的累计方差贡献率为62.199%，量表的结构效度、内容效度、效标效度 达到测量学要求。 结论 卒中危险因素初筛表具有较好的信度与效度，符合量表测量学的要求，可作为我国卒中风险 评估的工具。

Study on Reliability and Validity of the Risk Assessment Scale of Stroke

Objective To evaluate the reliability and validity of the risk assessment scales of stroke. Methods The primary stroke risk assessment and modiifed scale of Framingham Stroke Proifle (FSP) were performed on 130 cases, respectively to evaluate their reliability and validity. Results The Cronbach’s α was 0.701 for the scale, split-half reliability was 0.826 and the test-retest correlation was 0.94. Five factors were extracted by factor analysis, which contributed 62.199% of the variance. The satisfactory validity indexes were obtained including construct validity, content validity and criteria validity. Conclusion The risk assessment scales of stroke has a relatively good quality, and can be used as an evaluation tool for Chinese people stroke risk assessment.
