Comparison of Self-Reported Pain and the PAINAD Scale in Hospitalized Cognitively Impaired and Intact Older Adults After Hip Fracture Surgery

A positive correlation was found between the PAINAD and a self-report pain scale, providing evidence of concurrent validity. PAINAD scores were higher when patients were likely to experience pain than when unlikely, providing evidence of discriminant validity. The results of this study provide evidence supporting the validity and reliability of the PAINAD in the pain assessment of hospitalized post-orthopaedic surgical older adults who are unable or reluctant to self-report pain.
