In this cross-sectional prospective study, SOSG-OQ was strongly correlated with PROMIS PI (ρ = 0.78) and PROMIS PF (ρ = 0.71), and moderately correlated with PROMIS Depression (ρ = 0.58). Spine surgeons can consider using PROMIS domains in lieu of the SOSG-OQ in metastatic spine tumor patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
