Results published in The Journal of Shoulder and Elbow Surgery showed the Patient-Reported Outcomes Measurement Information System physical function and pain interference Computer Adaptive Tests had favorable psychometric properties for subacromial impingement syndrome.
Ilya Voloshin, MD, and colleagues collected Patient-Reported Outcomes Measurement Information System (PROMIS) physical function Computer Adaptive Test (CAT), pain interference CAT and American Shoulder and Elbow Surgeon scores among all patients who presented with subacromial impingement syndrome between January 2016 and August 2016. Researchers determined efficiency by the mean number of questions answered and created person-item maps to determine ceiling and floor effects as well as person reliability.
Results showed high efficiency, minimal ceiling and floor effects and excellent person reliability with both physical function and pain interference CAT. Although physical function and pain interference CAT both had moderate correlation to ASES function, researchers noted physical function CAT had moderate correlation to ASES total and poor correlation to ASES pain while pain interference CAT had moderate correlation to ASES pain and strong correlation with ASES total.
Of all domains tested, researchers found ASES function had the greatest respondent burden as well as the greatest ceiling effect. However, ASES function had relatively minimal floor effect, according to results. Person reliability was excellent in both physical function and pain interference CAT vs. good in ASES function, researchers noted. Results showed physical function and pain interference CAT matched or outperformed the ASES in all measures of psychometric performance for subacromial impingement syndrome.
“The study showed that PROMIS PF and PROMIS PI demonstrated favorable psychometric properties in efficiency, reliability and validity compared to ASES for patients with subacromial impingement syndrome,” Voloshin told Healio.com/Orthopedics. “We believe that collection of PROMIS PF and PROMIS PI together describes patient centered outcomes and experience more completely.” – by Casey Tingle
