医学研究生职业悲伤量表的编制及信效度检验

Development of professional grief scale for medical postgraduate students and its reliability and validity

目的:编制医学研究生职业悲伤量表,并检验其信效度。方法:结合职业悲伤整合模型,通过文献分析、质性访谈和邀请5名相关领域的专家评定量表条目内容的相关性并提出修改意见,形成量表初稿。对506名医学硕士研究生进行问卷调查,采用SPSS 25.0和AMOS 26.0软件检验量表的信效度。结果:医学研究生职业悲伤量表包括职业悲伤反应分量表和被剥夺的悲伤分量表,共41个条目。职业悲伤反应分量表包括情感反应(14个条目)、生理和认知反应(20个条目)两个维度,两因子模型累积方差贡献率为52.908%。被剥夺的悲伤分量表包括7个条目,单维度,方差贡献率为51.730%。验证性因子分析显示模型拟合良好。职业悲伤反应分量表和被剥夺的悲伤分量表的Cronbach’sα系数分别为0.947和0.850。结论:医学研究生职业悲伤量表具有良好的信效度,可以用于医学研究生职业悲伤的测评。

ObjectiveTo develop a professional grief scale for medical postgraduate students(PGS-MPS)and test its reliability and validity.MethodsBased on the integrated model of professional grief,the initial item pool was formed after literature analysis,semi-structured interviews,group discussion,and 5 experts were invited to assess the relevance of the items and provided revision suggestion.A total of 506 valid questionnaires were collected.SPSS 25.0 and AMOS 26.0 were used to test its reliability and validity.ResultsThe PGS-MPS included 41 items,including the professional grief reaction subscale and disenfranchised grief subscale.The professional grief reaction subscale included emotional reaction(14 items),physiological and cognitive reaction(20 items),and the cumulative variance contribution rate of the two factors model was 52.908%.Disenfranchised grief subscale included 7 items,with a single dimension and a variance contribution rate of 51.730%.Confirmatory factor analysis indicated the model fitting well.The Cronbach’sαcoefficients for the professional grief reaction subscale and disenfranchised grief subscale were 0.947 and 0.850,respectively.ConclusionThe PGS-MPS has good reliability and validity and can be used to evaluate professional grief of medical postgraduate students.
