Abstract

Abstract Individuals who experience burns are at higher risk of developing posttraumatic stress disorder and chronic pain. A synergistic relationship exists between posttraumatic stress disorder and chronic pain. We sought to evaluate the role of individual posttraumatic stress disorder symptom clusters as predictors of pain interference. We hypothesized that the hyperarousal and emotional numbing symptom clusters would be predictive of pain interference, even when accounting for the other two posttraumatic stress disorder symptom clusters, pain intensity, and other covariates. Multivariate linear regression analyses were completed using data from the Burn Model System National Database. A total of 439 adult participants had complete responses on self-report measures assessing posttraumatic stress disorder symptoms, pain intensity, and pain interference at 6-month after discharge and were included in analyses. Results indicate hyperarousal (B = .10, p = .03) and emotional numbing (B = .13, p = .01) posttraumatic stress disorder symptom clusters were each significantly associated with pain interference, even when accounting for pain intensity (B = .64, p < .001). Results highlight the importance of the emotional numbing and hyperarousal posttraumatic stress disorder symptom clusters in explaining pain interference. Findings suggest that when posttraumatic stress disorder symptoms or chronic pain are present, screening for and treating either condition may be warranted to reduce pain interference. Further, psychological interventions that target emotional numbing and hyperarousal posttraumatic stress disorder symptoms may be fruitful for promoting better coping with chronic pain and reducing pain interference.
