 This study found that the Workability Index, WI, and a single item question on workability are strongly associated with each other and can be used together to measure the status and progress of workability among women on long-term sick leave. Additionally, both measures were correlated with sick leave, health, and symptoms, suggesting that they may provide valuable information about the individual's overall well-being.
