Stanford HAQ 8-Item Disability Scale
Please circle the one best answer for your abilities.
Score the number circled for each item. If more than one consecutive number is circled for one item, code the higher number (more difficulty). If responses are not consecutive, code as blank. The disability index is the mean of the eight items. If more than 2 items are blank, do not score the index.
Tested on 611 subjects with chronic disease.

This is a short version of the 22-item disability scale in the Stanford Health Assessment Questionnaire. The 8-item scale was originally developed in Spanish. We have replaced the numbers with check boxes on the print version. It should be noted that the items have been chosen as they represent use of every major joint in the body. While closely related to an ADL scale this is not an ADL scale but rather a disability scale. This scale is available in Spanish.
