Review copy / Original version:

The original 1991 FIQ was modified in 1997, when 1 item (climb stairs) was added to the physical function subscale, hashmarks were added to the visual analogue scales to make scoring easier, and the words "including housework" were added to the 2 work-related items so that housework was recognized as a legitimate type of work. To avoid any confusion between both versions, each version has been numbered as follows:

FIQ 1991 will be version 1.0.
FIQ 1997 revised will be version 2.0.
For any new study, use of the FIQ 2.0 shall be required.

Original US English version 2.0 available for review purpose only. Please click here to access.
