PROMIS measures physical functioning on the short form and higher scores reflect better physical functioning with 10 questions on daily activities of life on a Likert scale ranging from 5 (no problem performing activity) to 1 (cannot do activity). Range on this measure is from 50 (best)-10 (worst).
