Relationship between occupational stress and mental health in offshore oil platform workers

Abstract

To investigate the relationship between occupational stress and mental health in offshore oil platform workers and to provide a scientific basis for protection of their mental health. A total of 768 workers on offshore oil platform were surveyed with the Occupational Stress Inventory Revised Edition and Symptom Check List-90 (SCL-90). The total score of Occupational Role Questionnaire (ORQ) for the workers (160.27±24.63) was significantly lower than the national norm (166.52±27.01) (P < 0.01); the total score of Personal Strain Questionnaire (PSQ) (101.96±19.8) was significantly higher than the national norm (92.45±17.33) (P < 0.01). The total score of Personal Resource Questionnaire (PRQ) for the workers was not significantly different from the national norm (P > 0.05), but the items of recreation, social support, and rational/cognitive found significant difference (P < 0.05). The total score of SCL-90 was positively correlated with all items of ORQ and PSQ (P < 0.01) and negatively correlated with all items of PRQ (P < 0.01). The multiple stepwise regression analysis showed that current work seniority, education background, drinking, role overload, role insufficiency, role ambiguity, responsibility, physical environment, and rational/cognitive conduct impacted the score of SCL-90 (P < 0.05). The mental health of workers on offshore oil platform is related to occupational stress, and role overload, role ambiguity, physical environment, and rational/cognitive conduct, etc, are closely associated with the workers' mental health.
