| Sumario: | Background: Strategies vary for identifying when mental and social health domains are important clinically, partly to address the risk of persistent symptoms. Purpose: This study assessed the concurrent validity of a set of 7 Patient-Reported Outcome Measurement Information System (PROMIS) with a validated multidomain measure (ie, Keele STarT Musculoskeletal (MSK)); and (2) reported physical therapist perceptions of the helpfulness of PROMIS outcomes. Methods: Orthopedic physical therapy patients completed the Keele MSK outcome and 7 PROMIS outcomes. Physical therapists rated "helpfulness" (0-10) during encounters of the PROMIS outcomes. Findings: The multivariate analysis of 88 participants showed that 3 PROMIS outcomes (Pain Interference, Self Efficacy of Symptom Management, and Fatigue) explained the most variance (r²=0.52, p<0.01) in the Keele Subgroups for Targeted Treatment for Musculoskeletal Tool (Keele MSK). Providers rated the PROMIS outcomes as "helpful" 69.5% of the time. Clinical Relevance: Single-domain PROMIS measures are a potential substitute for multidimensional outcomes. Conclusions: Single-domain PROMIS outcomes showed concurrent validity with the Keele STarT MSK Tool. Providers' perceptions suggest the PROMIS outcomes are clinically "helpful."
