Evaluation of a participatory ergonomics intervention in small commercial construction firms.

Background: Work-related musculoskeletal disorders (WMSD) among construction workers remain high. Participatory ergonomics (PE) interventions that engage workers and employers in reducing work injury risks have shown mixed results.

Methods: Eight-six workers from seven contractors participated in a PE program. A logic model guided the process evaluation and summative evaluation of short-term and intermediate impacts and long-term outcomes from surveys and field records.

Results: Process measures showed good delivery of training, high worker engagement, and low contractor participation. Workers' knowledge improved and workers reported changes to work practices and tools used; contractor provision of appropriate equipment was low (33%). No changes were seen in symptoms or reported physical effort.

Conclusions: The PE program produced many worker-identified ergonomic solutions, but lacked needed support from contractors. Future interventions should engage higher levels of the construction organizational system to improve contractor involvement for reducing WMSD. Am. J. Ind.
