Development of the Occupational Stressor Scale for Chinese Seafarers (OSSCS) / 中国心理卫生杂志

ABSTRACT

Objective:To develop a standardized scale for measuring Chinese seafarers' occupational stressor and test its reliability and validity.Methods:The scale was developed based onliterature research,open questionnaire investigation,interviews and expert discussion.531 seafarers from nationwide were recruited to complete the pre-investigation.Totally 422 seafarers were tested with formal version for further confirmatory factor analysis and internal consistency reliability.Forty-eight seafarers were tested for test-retest reliability.The criterion validity was tested with the Symptom Checklist 90 (SCL-90).Results:The Occupational Stressor Scale for Chinese Seafarers (OSSCS) included 52 items.Exploratory factor analysis generated 6 factors as occupational environment,health,interpersonal relationships,social environment,love and marriage,career development,which accounted for 62.0％ of the variance in all.Confirmatory factor analysisshowed that the model fit well (x2/df =2.28,CFI =0.94,IFI =0.93,NFI =0.91,TLI =0.92,RMSEA =0.06).The OSSCS scores were positively correlated with SCL-90 scores (r =0.37-0.67,Ps ＜ 0.01).Internal consistency reliabilities were 0.73-0.97,while test-retest reliabilities was 0.82-0.91.Conclusion:It indicates the developed Occupational Stressor Scale for Chinese Seafarers (OSSCS) is with good validity and reliability.
