Problem:
We assess the costs and consequences of a participatory ergonomics process at a Canadian car parts manufacturer from the perspective of the firm.
Method:
Regression modeling was used with interrupted time series data to assess the impact of the process on several health measures. Consequences were kept in natural units for cost-effectiveness analysis, and translated into monetary units for cost-benefit analysis.
Results:
The duration of disability insurance claims and the number of denied workers' compensation claims was significantly reduced. The cost-effectiveness ratio is $12.06 per disability day averted. The net present value is $244,416 for a 23-month period with a benefit-to-cost ratio of 10.6, suggesting that the process was worth undertaking (monetary units in 2001 Canadian dollars).
Discussion:
Our findings emphasize the importance of considering a range of outcomes when evaluating an occupational health and safety intervention.
Impact On Industry:
Participatory ergonomics process can be cost-effective for a firm.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
