Sickness absence in relation to psychosocial work factors among daytime workers in an electric equipment manufacturing company.
Associations between psychosocial work factors and sickness absence were investigated in a cross-sectional study of 833 daytime workers. Participants completed a questionnaire regarding psychosocial work factors using the US National Institute for Occupational Safety and Health Generic Job Stress Questionnaire (job control, quantitative workload, cognitive demands, variance in workload, intragroup conflict, intergroup conflict, supervisor support, coworker support, family support, job satisfaction and depressive symptoms) and the number of days of sickness absence within the previous year. Multivariate analyses of covariance with age and occupation as covariates (MANCOVA) were used to test the relationships between psychosocial work factors and sickness absence stratified by sex. In men, the age-adjusted MANCOVA showed that, quantitative workload was highest in the 0.5-4.5 d of sickness absence group (p<0.001). However, the levels of stress reactions (job satisfaction and depressive symptoms) in this group were almost identical to the levels recorded in the no sickness absence group. In contrast, low levels of job control (p<0.01), supervisor support (p<0.05), and job satisfaction (p<0.01) and higher symptoms of depression (p<0.001) were associated with 5 d or more sickness absence. In women, only high job satisfaction was associated with 5 d or more sickness absence (p<0.10). This study suggests that appropriate use of sickness absence at times of being exposed to high quantitative workload may help male workers to recover from stressful situations.
