Abstract:
Objective To develop a scale suitable for assessing work stressors among intensive care unit (ICU) nurses and to examine its reliability and validity. Methods The initial questionnaire of the ICU Nurses' Work Stressors Scale was constructed through literature review, ICU nurse interviews, and Delphi expert consultation. A total of 434 ICU nurses were selected as the validation subjects using the convenient sampling method. Item analysis, exploratory factor analysis, and confirmatory factor analysis were conducted to finalize the version of the ICU Nurses' Work Stressors Scale and evaluate its reliability and validity. Results The ICU Nurses' Work Stressors Scale included six dimensions and 34 items. Exploratory factor analysis extracted six common factors with a cumulative variance contribution rate of 77.8%. The results of confirmatory factor analysis demonstrated good model fit. The scale-level content validity index of the scale was 0.965, with item-level content validity index ranging from 0.850 to 1.000. The overall Cronbach's α coefficient of the questionnaire was 0.958, and the test-retest reliability was 0.986. In a survey of 434 ICU nurses testing with the scale, the total score ranged from 22.0-160.0 (82.6±20.6) points. The scores of each dimension including nursing profession, workload, working environment, patient care, family factors and interpersonal relationship were (14.5±4.2), (21.9±5.8), (7.0±2.1), (14.1±4.2), (6.3±2.5) and (18.8±5.7) points, respectively. Conclusion ICU Nurses' Work Stressors Scale demonstrates good reliability and validity and can serve as an effective tool for evaluating work stress among ICU nurses.
