工作不安全感问卷在医学院校教师中的初步修订

目的:在我国医学院校教师群体中对工作不安全感问卷进行修订并考察其信效度。方法:用工作不安全感问卷在我国医学院校教师群体中进行施测,通过项目分析、探索性因子分析和验证性因子分析对问卷的信效度进行检验。结果:经项目分析和探索性因子分析,删除了项目11、15、22,保留了其余27个项目,提取了特征值大于1的薪酬晋升不安全感、过度竞争不安全感、人际关系不安全感、工作丧失不安全感、工作执行不安全感5个因子。27个项目的题总相关系数均大于0.3,因子载荷大于0.5。5个因子累积解释总变异量的75.59%。问卷的建构效度和效标效度都符合心理测量学的要求。问卷的内部一致性信度Cronbach'sα系数为0.949,5个因子的Cronbach'sα系数分别为工作丧失不安全感0.966、薪酬晋升不安全感0.918、过度竞争不安全感0.847、人际关系不安全感0.888、工作执行不安全感0.730;组合信度分别为工作丧失不安全感0.967、薪酬晋升不安全感0.891、过度竞争不安全感0.856、人际关系不安全感0.919、工作执行不安全感0.749。结论:修订后的工作不安全感问卷具有良好的信效度,可以作为测量和评估我国医学院校教师工作不安全感的工具。

Revision of Job Insecurity Scale among Medical College Teachers

Objective:To revise the Job Insecurity Scale among medical college teachers and assess its reliability and validity.Methods:The Job Insecurity Scale was applied to measure the job insecurity of medical college teachers in China,and the reliability and validity of the Job Insecurity Scale were assessed by item analysis,exploratory factor a-nalysis and confirmatory factor analysis.Results:Item 11,15,22 were deleted by item analysis and exploratory factor analysis.The revised Job Insecurity Scale contained 5 factors,insecurity of job loss,insecurity of job execution,inse-curity of payment and promotion,insecurity of excessive competition,insecurity of interpersonal relationship,and the scale consisted of 27 items.The correlation coefficients between items and the total score were above 0.3,and the fac-tor loadings were over 0.5.The accumulating explanatory rate of the 5 factors was 75.59%.The construct validity and criterion validity of the scale met the psychometrics requirements.Cronbach's α coefficient of the scale was 0.949. Cronbach's αcoefficient of insecurity of job loss,insecurity of payment and promotion,insecurity of excessive compe-tition,insecurity of interpersonal relationship,insecurity of job execution was 0.966,0.918,0.847,0.888 and 0.730, respectively.The composite reliability of insecurity of job loss,insecurity of payment and promotion,insecurity of ex-cessive competition,insecurity of interpersonal relationship,insecurity of job execution was 0.967,0.891,0.856, 0.919,and 0.749,respectively.Conclusion:The revised Job Insecurity Scale is a reliable tool to assess the job insecuri-ty level of medical college teachers.
