Abstract
This study was conducted in order to determine how occupational stressors (psychosocial stressors and physical load) are related to psychological stress (symptoms) and musculoskeletal symptoms among staff of Finnish residential homes, nursing homes and home help services (n = 204). Data obtained from questionnaires was used to test two hypotheses: that psychosocial stressors (time pressure, troublesome patients with dementia) are associated with psychological stress, and that musculoskeletal disorders are associated with physical load. The authors also tested whether psychological stress has a mediating effect between psychosocial stressors and musculoskeletal symptoms. The findings supported the hypothesis regarding the mediating effect of psychological stress.
