Abstract: Objective

·To develop a scale for measurement of operating room nurses′ job stressor in China and analyze its reliability and validity.


·According to the literature review, combined with the working characteristics of the nurses in operating rooms, the first draft with 47 items was formulated by two groups of focus interviews among the operating room nursing managers and the operating room nurses. And the items were demonstrated and modified by Delphi expert consultation method to formulate the test version of Operating Room Nurses′ Job Stressor Scale. A test was conducted among the 355 nurses in operating rooms in three tertiary level A hospitals in Shanghai. The items were further screened and the scale was optimized according to the results of item analysis and exploratory factor analysis, and the reliability and the validity of the scale were analyzed.


·Twelve items were deleted and 8 items were modified by the first round of expert consultation. The test version of Operating Room Nurses′ Job Stressor Scale with 35 items was formulated by the second round of expert consultation. Item-level content validity indexes (I-CVI) were all ≥0.78 and scale-level average content validity index (S-CVI/Ave) was 0.91. A total of 355 questionnaires were distributed and the effective recovery rate was 100%. Thirty-five items were retained after item analysis. After 7 times of exploratory factor analyses, 6 items were deleted and 29 items were remained. A total of four factors were extracted ( ??problems in surgical nursing and patient nursing'' ??problems in working environment, workload and time allocation'' ??problems in nursing specialty and development'' and ??problems in management and interpersonal relationship''). The cumulative variance explanation rate of the four factors was 72.162%. The correlation coefficient between each dimension and the total score was higher than that between dimensions. S-CVI/Ave was 0.92. The internal consistency Cronbach′s α of the scale was 0.969, and those of the four dimensions were 0.936, 0.938, 0.872, and 0.943, respectively. The split-half reliability Spearman-Brown coefficient was 0.906. The retest reliability coefficient was 0.946.


·Operating Room Nurses′ Job Stressor Scale has good reliability and validity, which can be used to measure the source and degree of working pressure for the nurses in operating rooms.

Key words: operating room nurse, working pressure, job stressor, scale, reliability, validity
