title: The reliability and validity of a Korean translation of the ASAS Health Index and Environmental Factors in Korean patients with axial spondyloarthritis.
abstract: The objective of this study was to develop a Korean version of the Assessment of Spondyloarthritis International Society-Health Index/Environmental Factor (ASAS HI/EF) and to evaluate its reliability and validity in Korean patients with axial spondyloarthritis (SpA). A total of 43 patients participated. Translation and cross-cultural adaptation of the ASAS HI/EF was performed according to international standardized guidelines. We also evaluated validity by calculating correlation coefficients between the ASAS-HI/EF score and the clinical parameters. Test-retest reliability was excellent. The correlations among the mean ASAS-HI score and all tools of assessment for SpA were significant. When it came to construct validity, the ASAS HI score was correlated with nocturnal back pain, spinal pain, patients's global assessment score, the Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), Bath ankylosing spondylitis metrology index (BASMI) and EuroQoL visual analogue scale (EQ VAS) (r = 0.353, 0.585, 0.598, 0.637, 0.690, 0.430, and -0.534). The ASAS EF score was also correlated with the patient's global assessment's score, BASDAI, BASFI, BASMI, and EQ VAS score (r = 0.375, 0.490, 0.684, 0.485, and -0.554). The Korean version of the ASAS HI/EF can be used in the clinical field to assess and evaluate the state of health of Korean axial SpA patients.
