The SF-36 is scored using norm-based scoring procedures and scores ranging from 0-100; higher scores represent better health-related quality of life.
Change from baseline in Work Productivity and Activity Impairment Questionnaire (WPAI) score From baseline (Week 0) to Week 52 WPAI produces four types of scores: absenteeism (work time missed), presenteeism (impairment at work/reduced on-the-job effectiveness), work productivity loss (overall work impairment/absenteeism plus presenteeism), and activity impairment. The WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, that is, worse outcomes.
