AbstractPainimation, a novel digital pain assessment tool, allows patients to communicate their pain quality, intensity, and location using abstract animations and a paintable body image. This study determined the construct validity of pain animations and body image measures by testing correlations with validated pain outcomes in adults with sickle cell disease (SCD). Analyses used baseline data from a multisite randomized trial of 359 adults with SCD and chronic pain. Participants completed questionnaires on demographics, pain severity, frequency and interference, catastrophizing, opioid use, mood and quality of life, plus the Painimation app. Participants were categorized by selected pain animations, and were split into groups based on the proportion of painted body image. The "shooting" pain animation and greater body image scores associated with poorer pain outcomes in univariate analyses, except "happy" mood days. Potential confounding was evaluated by age, gender, race, education, disability, site, depression, and anxiety. Only depression scores significantly covaried in multivariate models, accounting for the effect of greater body image score and shooting animation on all outcomes except daily pain intensity. Both pain animations and body image measures correlated with validated pain outcomes, quality of life and mental health measures. This demonstrates animations and body image data can assess SCD pain severity, potentially with more accuracy than a 0-10 scale. In exploratory analyses, depression scores accounted for the association between Painimation and other pain outcomes. Future research will explore whether Painimation can differentiate biological and psychosocial pain components. PERSPECTIVE: This article presents the preliminary construct validity of Painimation in sickle cell disease (SCD) by examining the associations of "pain animations" and body area image data with daily e-diary and traditional self-report pain outcomes.Copyright © 2024.
