The patient-reported outcomes measurement information system (PROMIS) offers standardized assessment measures of clinically relevant patient-reported outcomes. This study evaluated the reliability and validity of select PROMIS measures with U.S. military veterans following orthopedic surgery. Data for the current study were collected as part of a pilot randomized control trial assessing the efficacy of a 1-day Acceptance and Commitment Therapy workshop on persistent postsurgical pain in at-risk veterans undergoing orthopedic surgery. Sixty-seven participants completed surveys 3 months after surgery. Participants completed the following PROMIS instruments: PROMIS Anxiety Short Form 8a, PROMIS Depression Short Form 8b, and PROMIS Pain Interference Short Form 8a. PROMIS measures were compared to the Generalized Anxiety Disorder 7-Item Scale, the Patient Health Questionnaire 9-Item Scale, and the Brief Pain Inventory Pain Interference subscale, respectively. All three PROMIS measures demonstrated excellent internal consistency (Cronbach's alpha s ranged from .93 to .96) and each loaded onto a single factor. The PROMIS measures were moderately correlated with their respective comparison measures (r= .69 to .76). The PROMIS anxiety and PROMIS depression measures were highly correlated to one another (r= .91). Findings highlight the potential utility of these PROMIS measures in veterans following orthopedic surgery and the overlap between the PROMIS depression and anxiety measures in this sample.
