Work Productivity and Activity Impairment Questionnaire:
Specific Health Problem  V2.0 (WPAI:SHP)*

The following questions ask about the effect of your PROBLEM on your ability to work and perform regular activities.  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.

2)  During the past seven days, how many hours did you miss from work because of problems associated with your PROBLEM?  Include hours you missed on sick days, times you went in late, left early, etc., because of PROBLEM.  Do not include time you missed to participate in this study.
 _____ HOURS

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?
 ______HOURS

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 PROBLEM 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 PROBLEM affected your work only a little, choose a low number.  Choose a high number if PROBLEM affected your work a great deal.  

Consider only how much PROBLEM affected 
productivity while you were working.

Recent analyses suggest that the accuracy of responses to questions 5 and 6 by some subjects in the WPAI:SHP might be improved by repeating the instructions directly  above the scales.  Version 2.0 has these instructions, but in all other respects is the same as the original WPAI:SHP.

To adapt the WPAI to a specific disease/ condition, replace PROBLEM throughout with the name of the disease/ condition.  To use the WPAI in clinical practice, and not as part of a study or clinical trial, use the Clinical Practice Version (CPV) which omits reference to participation in the study in questions 2 and 3.
