Arthritis Self-Efficacy Scale
For each of the following questions, please circle the number that corresponds to how certain you are that you can do the following tasks regularly at the present time.
Items (using the same format as above):
The score for each item is the number circled. If two consecutive numbers are circled, code the lower number (less self-efficacy). If the numbers are not consecutive, do not score the item. The score for the scale is the mean of the eight items. If more than two items are missing, do not score the scale.
Tested on 175 subjects with arthritis.

This 8-item scale is from the original 20 item Arthritis Self-Efficacy scale. We use this scale now, as it is much less burdensome for subjects. The full 20 item scale is in the PDF document (see PDF link at the bottom of this page). For internet studies, we add radio buttons below each number. There is another way that we use to format these items, which takes up less space on a questionnaire, shown also in the PDF document. This scale is available in Spanish.
