Development of productivity loss measures
Productivity loss could be defined as the difference between what employees normally produce and how much they produce when affected by health problems. Other factors besides employee health such as work environment factors may also affect the performance of the employee, and only measuring the contribution of ill-health might underestimate the actual productivity loss which is mostly a cost to the employer.
In our previous work within this project, two single-item questions based on the Swedish version of Work Productivity and Activity Impairment General Health questionnaire (WPAI-GH version 1.0) have been developed. The questions adopted a performance-based approach to estimate health- and work environment-related productivity losses. These two measures of productivity loss, health related and work environment–related production loss, and their associations with health status and work environment factors have been tested.
In further studies, the questions developed in the research group, is currently being tested for other psychometric properties and to standardize and check for measurement uncertainties using Rasch analysis. The single item questions are intended to be used to make a business case for a healthy workplace and employees by investing in occupational safety and health (OSH).
