Abstract

The Work Productivity Short Inventory (WPSI) was developed to quickly estimate decrements in productivity associated with 15 common disease conditions. Three versions of the WPSI were developed that differed according to the length of the recall period (12 months, 3 months, or 2 weeks). The content, predictive, and construct validity of metrics generated from the WPSI were assessed based on response patterns found in the 3 versions and via comparison to information in national data sources or in the subject company's medical care claims and short-term disability program files. The WPSI provided evidence of content and construct validity to support its intended purpose. Evidence for predictive validity was weaker but still present. The WPSI can be used to provide information on the relative importance of health conditions that affect productivity at work for a large group of employees.
