Protocol - School and Work Attendance - Adult
The Work Productivity and Activity Impairment Questionnaire (WPAI) is a 6-item, self-report instrument that measures impact of health problems on work attendance over the last 7 days.
The Hemophilia Inhibitor Research Working Group suggests that the phrase "health problems" be replaced with "hemophilia."
Work Productivity and Activity Impairment Questionnaire:
General Health V2.0 (WPAI:GH)
The following questions ask about the effect of your health problems on your ability to work and perform regular activities. By health problems we mean any physical or emotional problem or symptom. Please fill in the blanks or circle a number, as indicated.
1. Are you currently employed (working for pay)? ____ NO ____ YES
If NO, check "NO" and skip to question 6.
The next questions are about the past seven days, not including today.

days, times you went in late, left early, etc., because of your health problems. Do not include time you missed to participate in this study.
3. During the past seven days, how many hours did you miss from work because of any other reason, such as vacation, holidays, time off to participate in this study?
4. During the past seven days, how many hours did you actually work?
_____HOURS (If "0," skip to question 6.)
5. During the past seven days, how much did your health problems affect your productivity while you were working?
Think about days you were limited in the amount or kind of work you could do, days you accomplished less than you would like, or days you could not do your work as carefully as usual. If health problems affected your work only a little, choose a low number. Choose a high number if health problems affected your work a great deal.
