Musculoskeletal pain was chosen as the measure forworkers’ subjective health because such symptoms arecommon among this group of workers (Torp et al., 2001a,1996) and because they often are related to both physicaland psychosocial work environment. Musculoskeletal painwere measured by six of the questions in the SubjectiveHealth Complaints Questionnaire (Eriksen et al., 1999).The respondents were asked whether they had experiencedpain within the past 30 days from the head, neck, upperback, lower back, shoulders and arms.
