Concurrent Validity of PROMIS With DASH and DVPRS in Transhumeral Amputees

Abstract

Background:

We sought to assess whether select domains of the Patient-Reported Outcomes Measurement Information System (PROMIS) significantly correlate with the Disabilities of the Arm, Shoulder, and Hand (DASH) score and the Defense and Veterans Pain Rating Scale (DVPRS) among transhumeral amputees.

Methods:

We prospectively administered DASH, DVPRS, and PROMIS (including Upper Extremity, Pain Interference, and Pain Behavior domains) testing to patients presenting for consideration of osseointegration after transhumeral amputation. Concurrent validity was assessed via Pearson correlation testing.

Results:

The mean DASH score of the cohort was 32.8. The mean DVPRS score was 1.8. The mean PROMIS scores were 33.8, 50.5, and 50.6 for Upper Extremity, Pain Interference, and Pain Behavior domains, respectively. Pearson testing demonstrated a significant, inverse correlation between DASH and PROMIS Upper Extremity scores (r = −0.85, P = .002). There was also significant correlation between DVPRS and PROMIS Pain Interference scores (r = 0.69, P = .03). The PROMIS Pain Behavior domain did not significantly correlate with either DASH or DVPRS.

Conclusions:

Patient-Reported Outcomes Measurement Information System Upper Extremity and Pain Interference scores demonstrated significant concurrent validity with traditional measures (DASH and DVPRS) of patient-reported outcome in our population of transhumeral amputees.
