Abstract

Background: There is a paucity of literature assessing 2 of the commonly used static Patient-Reported Outcomes Measurement Information System (PROMIS) forms (PROMIS Global-10 and PROMIS Physical Function Short Form 10a [PF SF 10a]) and the Foot and Ankle Ability Measure Activities of Daily Living (FAAM ADL).

Methods: The PROMIS Global-10, PROMIS PF SF 10a, and FAAM ADL were compared among new foot and ankle patients. Spearman rho (ρ) correlations were calculated, and ceiling and floor effects were determined.

Results: The FAAM ADL demonstrated strong correlations with PROMIS PF SF 10a, P = .88, 95% confidence interval (CI): 0.86-0.90, P < .001, and PROMIS Global-10 Physical Health (P = .75, 95% CI: 0.71-0.78, p < .001). The FAAM ADL and PROMIS Global-10 Mental Health demonstrated a moderate correlation (P = .41, 95% CI: 0.34-0.47, P < .001). No PROM demonstrated an appreciable floor effect. The PROMIS Global-10 Physical Health demonstrated the lowest ceiling effect (n=11 [1.6%]).

Conclusion: Because the PROMIS Global-10 captures physical health adequately, provides mental health insight, and performs as well (if not better), we recommend the PROMIS Global-10 among the PROMs studied.Level of Evidence: Level III.
