中文版临床推理与反思自评量表在护理学专业学生中的信效度测试研究

Reliability and validity of the Chinese version of Self-Assessment of Clinical Reasoning and Reflection in nursing undergraduates

目的对中文版临床推理与反思自评量表(Self-Assessment of Clinical Reasoning and Reflection,SACRR)进行信效度检验。方法便利选取北京协和医学院2014级~2016级四年制护理学专业228名本科生为研究对象,填写中文版SACRR量表,进行信度、效度测评。两周后,选取其中30名学生再次填写中文版SACRR量表,测定重测信度。采用SPSS 22.0软件进行数据分析。结果中文版SACRR量表的克朗巴赫系数为0.754,重测信度为0.785;量表内容效度S-CVI/Ave为0.98;探索性因子分析提取4个公因子,即信息系统化、分析问题、寻找真相、反思能力,累计方差贡献率为57.336%。本研究中采用中文版批判性思维能力测量表(Chinese Version of Critical Thinking Disposition Inventory,CTDI-CV)作为效标效度检测的标准。效标关联效度测评显示,中文版SACRR量表测量内容与CTDI-CV量表在寻求真相、系统化能力和自信心3个维度相关,Pearson相关系数分别为0.215、0.172、0.343(均P<0.05)。结论中文版SACRR量表信效度较好,为今后评价护理学专业学生临床推理能力提供了参考。

Objective To test the reliability and validity of Chinese version of Self-Assessment of Clinical Reasoning and Reflection (SACRR). Methods Totally 228 undergraduates majoring in four-year nursing from 2014 to 2016 in Peking Union Medical College were tested by Chinese version of SACRR. Two weeks later, 30 subjects were selected to fill in Chinese version of SACRR again and test the retest reliability. The data of reliability and validity were analyzed by SPSS 22.0 software. Results The Cronbach's α of the SACRR was 0.754, and the total scale retest reliability was 0.785.The content validity of the scale (S-CVI/Ave) was 0.98. Four factors were extracted by using Exploratory Factor Analysis: Information System, Analysis of Problems, Finding Truth and Reflective Ability, the cumulative variance contribution rate was 57.336%.In this study, the scores measured by Chinese Version of Critical Thinking Disposition Inventory (CTVI-CV) were used as the existing criteria for validity testing.The criterion-related validity test showed that the content of Chinese version of SACRR was significantly correlated with the three dimensions of CTDI-CV: truth-seeking, systematic ability and self-confidence, Pearson correlation coefficient was 0.215, 0.172, 0.343 (all P<0.05). Conclutions Chinese version of SACRR has good reliability and validity, which provides a reference for evaluating the clinical reasoning ability of nursing students in the future.
