Abstract
Purpose: Pain intensity in chronic low back pain (CLBP) is often assessed using pain items embedded in multidimensional patient-reported outcome measures (PROMs), but differences in scale format and recall period may limit score interchangeability. The purpose of this study was to evaluate the association and agreement among three commonly used pain intensity items derived from ODI, SRS-22, and COMI in adults with CLBP, with and without scoliosis.
Methods: Secondary cross-sectional analysis of an observational cohort. From 1,092 eligible subjects (552 scoliosis-associated LBP; 540 non-scoliosis LBP), we included participants with complete pain items: ODI Item 1 (pain "at the moment", 1-6), SRS-22 pain item (past month, 1-5), and COMI pain (maximum of back/leg pain over the past week, 0-10). Agreement was assessed using Spearman's rho, Kendall's W, and intraclass correlation coefficients (ICC), overall and by pathology group and sex.
Results: The final sample included 417 adults (88% female; mean age 65 ± 10 years): 319 SLBP and 98 LBP. Across all subjects, correlations were moderate to strong (rho 0.50-0.70) with substantial ordinal agreement (W = 0.74) but only moderate quantitative concordance (ICC = 0.45). Estimates were similar in SLBP and LBP (rho 0.49-0.70; W 0.74-0.79; ICC 0.43-0.53) and did not differ by sex.
Conclusions: Pain items from ODI, SRS-22, and COMI rank patients similarly but yield non-interchangeable absolute scores in CLBP, irrespective of scoliosis. Consistent instrument selection is recommended when comparing or pooling pain outcomes.
期刊介绍：
"European Spine Journal" is a publication founded in response to the increasing trend toward specialization in spinal surgery and spinal pathology in general. The Journal is devoted to all spine related disciplines, including functional and surgical anatomy of the spine, biomechanics and pathophysiology, diagnostic procedures, and neurology, surgery and outcomes. The aim of "European Spine Journal" is to support the further development of highly innovative spine treatments including but not restricted to surgery and to provide an integrated and balanced view of diagnostic, research and treatment procedures as well as outcomes that will enhance effective collaboration among specialists worldwide. The “European Spine Journal” also participates in education by means of videos, interactive meetings and the endorsement of educative efforts.
