As chronic pain contributes to tremendous personal and societal costs, efforts at identifying and understanding pain‐related disability via the biopsychosocial model have become increasingly important in addressing pain‐related health outcomes. This study attempted to compare the predictive ability of the Pain Disability Questionnaire against other established measures in terms of health and pain‐related outcomes. The sample consisted of 254 adult chronic pain patients seeking treatment through an interdisciplinary chronic pain management clinic. Participants were administered a battery of assessments including the Pain Disability Questionnaire and other established measures of health and pain‐related outcomes (e.g., NIH PROMIS measures) at baseline and post‐treatment time points. Results demonstrated convergent validity between the Pain Disability Questionnaire and the other study measures. Hierarchical regression analyses revealed significant associations between pain‐related disability as measured by the Pain Disability Questionnaire and a range of biopsychosocial outcomes. Pain Disability Questionnaire scores, as placed in categorical severity levels, demonstrated good discriminative abilities in terms of predicting health‐related factors. These findings support the clinical use of the Pain Disability Questionnaire as an empirically supported predictor of health‐related outcomes as compared with other established measures of pain and health outcomes.
