Sleep disorders, occupational stressors, personalities, and occupational strain response were measured with questionnaires. RESULTS: Workers with high psychological demands, job stressors,depressive symptoms,physical symptoms, daily life stress, work locus of control had higher sleep disorders scores than their counterparts (P < 0.01 or P < 0.05), workers with high job control had lower sleep disorders scores than their counterparts (P < 0.05). Sleep disorders were positively related to psychological demands, job stressors, depressive symptoms, physical symptoms, daily life stress, state-anxiety, strait-anxiety, and susceptibility to stress (P < 0.01 or P < 0.05), but negatively to job control and mental health (P < 0.05).
