临床医学专业学生职业认同量表的修订与验证

Revision and validation of professional identity scale for medical students

目的修订临床医学专业学生(简称临床医学生)职业认同量表并进行初步验证。方法2019年11月至2020年5月,基于社会认同理论和既往职业认同研究结果,结合文献内容分析、课题小组讨论形成量表条目池,再通过专家评审增减量表维度和条目,确定临床医学生职业认同量表。2020年6月,采取整群抽样以黑龙江省4所高校的5807名临床医学生为样本进行大样本实证测量。应用克朗巴赫系数、分半信度和因子分析等方法检验量表信度和效度;对临床医学生职业认同现状进行描述性分析。结果临床医学生职业认同量表包含职业认知、职业情感、职业承诺、职业行为、职业期望和职业价值观6个维度,共27个条目,总分162分。各维度克朗巴赫系数为0.81~0.94,分半信度系数为0.72~0.91。经主成分分析提取6个公因子后累积方差贡献率达82.32%。临床医学生职业认同总分为(134.24±21.53)分,处于中等偏高水平,其中职业行为维度评分较高[(29.02±5.31)分]。结论临床医学生职业认同量表具有良好的信度和效度,能够合理反映临床医学生的职业认同现状。

Objective To revise and validate the a professional identity scale for medical students and conduct preliminary validation.Methods From November 2019 to May 2020,a scale item pool was formed based on social identity theory and previous research results on professional identity,combined with literature content analysis and project group discussion.The scale dimensions and items were added and subtraction through expert review to determine the scale of professional identity for medical students.In June 2020,a large sample of 5807 medical students from 4 universities in Heilongjiang Province was tested by cluster sampling.Kronbach coefficient,split half reliability and factor analysis were used to test the reliability and validity of the scale.The present status of professional identity of medical students was analyzed.Results The professional identity scale of medical students was composed of 27 items in 6 dimensions,including professional cognition,professional emotions,professional commitment,professional behavior,professional expectations,and professional values.The total score of the scale is 162 points.Cronbach′s coefficients of each dimension were 0.81-0.94,the split reliability was 0.72-0.91.The cumulative variance contribution rate reached 82.32%after extracting six common factors by principal component analysis.The total score of professional identity of medical students was(134.24±21.53)points,which was at a medium high level,and the average score of professional behavior dimension was(29.02±5.31)points.Conclusions The professional identity scale of medical students has good reliability and validity,and can reasonably reflect the status quo of professional identity of medical students.
