Development and application of a specialized scale of occupational stressors for medical staff
Journal Title: Shanghai Journal of Preventive Medicine - Year 2022, Vol 34, Issue 10
Abstract
ObjectiveTo develop a professional occupational stress scale for medical staff ï¼CSSMï¼ and test its reliability and validityï¼ so as to provide a technical tool for the evaluation and management of medical staff occupational stress.MethodsThe initial index item pool was formed by literature retrievalï¼ in-depth interview and expert evaluation. Pre-survey questionnaires were distributed in April 2021ï¼ stratified sampling was used to randomly select 1 tertiary hospitalï¼ 2 secondary hospitals and 1 community health service center in Shanghai. Sampling was performed according to the number of medical staff in all level hospitals and the proportion of doctorsï¼ nurses and medical technicians. 848 valid questionnaires were collected. Item differentiation methodï¼ correlation analysis and exploratory factor analysis were used to filter the pre-survey item pool and form a formal scale. From June to July 2021ï¼ stratified sampling method was used to carry out formal survey with formal scaleï¼ and the reliability and validity of the scale were verified. A total of 5 510 valid questionnaires were collected. Confirmatory factor analysis was used to test the construct validity of the scale. Job burnoutï¼ sleep disorder and job demand-autonomy ï¼-supportï¼ model occupational stress scales were used as calibration scalesï¼ respectively. Pearson correlation analysis was used to test the scale's calibration validity and aggregate validityï¼ and Cronbach's α coefficient was used to evaluate the scale's reliability.ResultsThrough project differentiation methodï¼ correlation analysisï¼ exploratory factor analysis on the preliminary survey item poolï¼ we produced the formal scale of 7 dimensions and 32 itemsï¼ respectivelyï¼ including "career development"ï¼ "interpersonal relationship"ï¼ "working overtime and work-life imbalance"ï¼ "physical environment"ï¼ "the doctor-patient relationship"ï¼ "social environment"ï¼ "work load". The cumulative variance contribution rate of common factors in exploratory factor analysis was 65.937%ï¼ and the factor loading value of each item ranged from 0.513 to 0.880. The scale was used for formal investigation to verify the reliability and validity of the scale. The goodness of fit index ï¼GFIï¼ï¼ comparative fit index ï¼CFIï¼ and root mean square error of approximation ï¼RMSEAï¼ were 0.913ï¼ 0.909 and 0.064ï¼ respectively. The scores of the scale and all dimensions were positively correlated with the scores of occupational stress in the mode of job burnoutï¼ sleep disorder symptoms and job demand-autonomy ï¼r=0.235â0.754ï¼ P<0.05ï¼. The Cronbach's α coefficients of the total amount table and each dimension ranged from 0.743 to 0.937ï¼ showing good reliability and validity.ConclusionCSSM has good reliability and validityï¼ which provides a measurement and assessment tool for the targeted prevention of occupational stress in medical staff. The popularization and use of this scale in other regions need further verification.
