Title Participatory intervention for workplace improvements on mental health and job performance among blue-collar workers: A cluster randomized controlled trial
Bibliographic information May 2009, Vol.51, No.5, p.554-563. Illus. 46 ref.
Abstract To explore the effect of participatory intervention for workplace improvement on mental health and job performance, 11 assembly lines were randomly allocated to six intervention and five control lines (47 and 50 workers, respectively). Participants were surveyed by means of questionnaires at baseline and at the end of the intervention. General Health Questionnaire scores significantly deteriorated in the control group, whereas the score remained at the same level in the intervention group. Health and Work Performance Questionnaire scores increased in the intervention group, but decreased in the control group. Participatory intervention for workplace improvement appears effective against deterioration in mental health and for improving job performance.
