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
