Does recall period matter? Comparing PROMIS^® physical function with no recall, 24-hr recall, and 7-day recall.

ABSTRACT:

Purpose

To evaluate the influence of recall periods on the assessment of physical function, we compared, in cancer and general population samples, the standard administration of PROMIS Physical Function items without a recall period to administrations with 24-hour and 7-day recall periods.

Methods
