The use of global health items permits an efficient way gathering general perceptions health. These provide useful summary information about and are predictive care utilization subsequent mortality. Analyses 10 self-reported obtained from internet survey as part the Patient-Reported Outcome Measurement Information System (PROMIS) project. We derived scores items. estimated associations with EQ-5D index score PROMIS physical function, pain, fatigue, emotional distress, social domain scores. Exploratory confirmatory factor analyses supported a two-factor model. Global (GPH; 4 on overall health, fatigue) mental (GMH; quality life, satisfaction activities, problems) scales were created. had internal consistency reliability coefficients 0.81 0.86, respectively. GPH correlated more strongly than did GMH (r = 0.76 vs. 0.59). most pain impact −0.75) whereas depressive symptoms −0.71). Two dimensions representing underlie in PROMIS. can be used to efficiently summarize patient-reported outcome studies.
