Abstract
ObjectiveWe combined anchor- and distribution-based methods to establish minimally important differences (MIDs) for six Patient-Reported Outcomes Measurement Information System (PROMIS)-Cancer scales in advanced-stage cancer patients.Study Design and SettingParticipants completed 6 PROMIS-Cancer scales and 23 anchor measures at an initial (n=101) assessment and a follow-up (n=88) assessment 6–12 weeks later. Three a priori criteria were used to identify usable cross-sectional and longitudinal anchor-based...
