Objective: to appraise available measurement evidence on global measures of presenteeism against the requirements of the OMERACT filter
Work-stream 2Multi-item approaches to measure at-work limitations/productivity loss
Objective: to appraise available measurement evidence on multi-item measures of presenteeism against the requirements of the OMERACT filter
Work-stream 3Contextual factors of worker productivity
Objective: to develop criteria for identifying contextual factors of worker productivity and guidelines to consider contextual factors in the application of worker productivity outcome measures
Work-stream 4Interpretability of worker productivity outcome measures
Objective: to estimate cut-scores associated with the Patient Acceptable State (PAS) and score changes associated with the Minimally Important Difference (MID) of worker productivity outcome measures
