心脏康复障碍量表的汉化及信效度检验

The Cardiac Rehabilitation Barriers Scale (CRBS):translation and validation in cardiovascular patients

目的 汉化心脏康复障碍量表并检验信效度。方法 根据Brislin翻译模型对心脏康复障碍量表进行翻译、文化调适和修订,并对260例心脏疾病患者进行调查,验证中文版心脏康复障碍量表的信效度。结果 中文版心脏康复障碍量表21个条目的临界比率值(CR)为3.120~8.251,高、低分组患者之间差异有统计学意义(均P<0.05)。各维度与条目间相关系数0.504~0.866,各维度间相关系数0.405~0.768。量表总体Cronbach′s α系数0.920,4个维度Cronbach′s α系数为0.816~0.911;总量表重测信度为0.869,I-CVI为0.811~1.000,S-CVI/UA为0.841,S-CVI/Ave为0.940。共提取4个公因子,累计方差贡献率为64.701%。结论 中文版心脏康复障碍量表具有较好的信效度,可为心脏疾病患者康复护理方案制订和评估提供参考。

Objective To introduce and translate the Cardiac Rehabilitation Barriers Scale(CRBS)into a Chinese version,and to test its reliability and validity.Methods In pursuant to Brislin translation model,CRBS was translated and back translated,culturally adjusted and revised,to form a Chinese version.A total of 260 patients with heart diseases were surveyed to verify the reliability and validity of the Chinese version.Results The critical ratio(CR)values of 21 items were between 3.120-8.251,with significant differences in all items between high-versus low-score groups(all P<0.05).Dimension-item correlation coefficients were between 0.504-0.866,and the dimension-dimension correlation coefficients were between 0.405-0.768.The Cronbach′sαcoefficient was 0.920 for the overall scale,and between 0.816-0.911 for the four dimensions;the test-retest coefficient was 0.869 for the whole scale.I-CVI was between 0.811-1.000,S-CVI/UA was 0.841,and S-CVI/Ave was 0.940.Four factors were extracted and collectively explained 64.701%of total variation.Conclusion The Chinese version CRBS has good reliability and validity.It can provide a basis for formulation of individual rehabilitation nursing plan and assessment for patients with heart diseases.
