Effects of a Workplace Intervention Targeting Psychosocial Risk Factors on Safety and Health Outcomes

Abstract EN

The goal of this study was to test the effectiveness of a workplace intervention targeting work-life stress and safety-related psychosocial risk factors on health and safety outcomes.

Data were collected over time using a randomized control trial design with 264 construction workers employed in an urban municipal department.

The intervention involved family- and safety-supportive supervisor behavior training (computer-based), followed by two weeks of behavior tracking and a four-hour, facilitated team effectiveness session including supervisors and employees.

A significant positive intervention effect was found for an objective measure of blood pressure at the 12-month follow-up.

However, no significant intervention results were found for self-reported general health, safety participation, or safety compliance.

These findings suggest that an intervention focused on supervisor support training and a team effectiveness process for planning and problem solving should be further refined and utilized in order to improve employee health with additional research on the beneficial effects on worker safety.
