Validity of the PROMIS Physical Performance Scale in Determining Frailty and Physical Ability in Community-Dwelling Elderly

In many clinical settings, therapists are continuously seeking efficient and valid assessments for older adults to determine their physical abilities and functional status. The Patient Reported Outcome Instrument System (PROMIS) is a newly developed computer adapted test (CAT) that is being incorporated into electronic medical records and has been reported to assess a person’s physical function. The current gold standard to assess different levels of frailty and physical function in older individuals is the Modified Physical Performance Test (mPPT). However, the mPPT is a lengthy performance based outcome measure that takes time to administer. The purpose of this study is to determine a more quick and efficient test to determine physical function
