| Abstract |
The objective of this study was to assess the effect of a participatory ergonomics intervention on psychosocial factors among kitchen workers. It was conducted in the form of a cluster randomised controlled trial involving 504 workers in 119 municipal kitchens in four cities in Finland, from 2002 to 2005. The kitchens were randomised to 59 intervention and 60 control groups. The intervention lasted 11-14 months and was based on the workers' active participation in work analysis, planning and implementing the ergonomic changes aimed at decreasing the physical and mental workload. Mental stress, mental strenuousness of work, hurry, job satisfaction, job control, skill discretion, co-worker relationships and supervisor support were measured. Data were collected by questionnaire at baseline, at the end of the intervention, and at a 12-month follow-up. At the end of the intervention, the odds ratio (OR) of job dissatisfaction for the intervention group as compared with the control group was 3.0, of mental stress 2.3 and of poor co-worker relationships 2.3. At the 12-month follow-up, the OR of job dissatisfaction was 3.0. Analysis of the independent and joint effects of the intervention and unconnected organisational reforms showed that adverse changes were accentuated among those with exposure to both. No favourable effects on psychosocial factors at work were found. The adverse changes were due to a joint effect of the intervention and unconnected organisational reforms. The findings do not support the usefulness of this kind of intervention in changing unsatisfactory psychosocial working conditions. |
