Study hypothesis
It has been hypothesised that, because participatory ergonomics (PE) implementation strategies intervene at all phases of behavioural change for the various stakeholders, they may be successful in increasing the use of ergonomic measures at worksites. A PE implementation strategy is defined as the involvement of people in planning and controlling a significant amount of their own work activities with sufficient knowledge and power to influence processes and outcomes to achieve desirable goals.

Primary outcome measure
Use of ergonomic measures (doing), assessed by means of worksite observations and questionnaires at baseline and after six months.
Secondary outcome measures
Behavioural change phases among employers (awareness, accessibility, understanding, wanting, intention and ability) and behavioural change phases among employees (awareness, wanting and ability). The behavioural change phases of the workers and the employers were determined by questionnaires and interviews respectively. Performance indicators for the PE implementation strategy were assessed through observations by researchers during the implementation process and through questionnaires completed by workers.
