Integrated Approaches to Health and Safety in a Dynamic Construction Work Environment

Study Overview
=================
Brief Summary
-----------------
All the Right Moves for Subcontractors aims to improve safety, health and well-being, through the development of a communication infrastructure with supplemental tools where construction workers and company mangers (project, operations and safety) work together to collaboratively identify problems and strategies to improve their conditions of work. The intervention is grounded in the key characteristics of integrated organizational interventions to improve workers' health safety and well-being detailed in Harvard Center for Work, Health and Well-being's Implementation Guidelines (McLellan et al, 2016). The intervention involves a cyclical approach through which the research team facilitate a participatory process to identify workers' health concerns, prioritize these concerns, use an action planning process to identify and operationalize solutions, and develop a company-specific evaluation plan to measure change. We will evaluate this program by measuring safety climate, health climate, pain and injury and health behaviors.
