Severity categorization for PROMIS pain interference and pain behavior scores in individuals with SCD who likely have chronic pain and those who likely do not have chronic pain. Displayed are median T-scores and interquartile ranges of the PROMIS pain interference and pain behavior domains in the chronic pain group and no chronic pain group according to published validated PROMIS score cut points. Data show distinct ranges of scores for both domains without overlap, indicating moderate impairment for those with chronic pain and mild impairment or normal functioning for those without chronic pain.
