Context: The Patient-Reported Outcomes Measurement Information System (PROMIS) item banks have been validated for general populations, but their application to high-functioning patient populations remains speculative.Objective: To examine the measurement properties of the PROMIS physical function item bank, version 1.0, when applied to individuals representing high levels of physical ability.Design: Cross-sectional study. Setting: National Collegiate Athletic Association Division I and III collegiate athletic training rooms and intramural events.Patients or Other Participants: A heterogeneous sample of 215 adults from Division I or Division III collegiate or recreational sports volunteered for this study. Participants were divided into 4 groups depending on sport activity and injury status: healthy collegiate (HC; 33 men, 37 women; age ¼ 19.7 6 1.1 years), injured and currently active in sport (IP; 21 men, 29 women; age ¼ 19.9 6 1.2 years), injured and currently not active in sport (INP; 12 men, 18 women; age ¼ 19.7 6 1.3 years), and healthy recreational (HR; 47 men, 18 women; age ¼ 20.1 6 1.4 years).Main Outcome Measure(s): Participants completed 2 assessments: (1) an injury-history questionnaire and (2) the PROMIS physical function item bank, version 1.0, in computeradaptive form. Mean PROMIS physical function scores were determined for each group.Results: The PROMIS physical function score for the HC group (61.7 6 6.0) was higher than for the IP (54.9 6 7.5) and INP (44.1 6 8.2) groups (P , .001). The IP group had a higher score than the INP group (P , .001). Mean PROMIS scores were not different between the HC and HR participants (mean difference ¼ 1.9, P ¼ .10).Conclusions: The computer-adaptive PROMIS physical function item bank, version 1.0, accurately distinguished injury status in elite-level athletes on a physical function latent trait continuum. Although it was unable to distinguish HC athletes from HR athletes, exposing a possible ceiling effect, it offers potential for use as an outcome instrument for athletic trainers and other sports medicine clinicians.Key Words: athletic injuries, clinical decision making, PROMIS
Key PointsThe Patient-Reported Outcomes Measurement Information System (PROMIS) physical function item bank, version 1.0, accurately differentiated physical function in collegiate athletes who were healthy, injured and participating, or injured and not participating. The PROMIS did not distinguish healthy collegiate athletes from healthy recreational athletes. The most difficult sport-related items address running speed and distance, which may not accurately distinguish elite athletes from the general population. Based on these findings, the PROMIS may be a useful tool for assessing physical ability in the early stages of rehabilitation. However, it seems to lack the ability to identify healthy individuals with unrestricted participation.
