A significant increase in risk was seen in this study in 0.2% of patients when blocks were recut for further sampling, with minor increases in 2%. While embedding issues only rarely resulted in clinically significant sampling error, the 3 significantly underdiagnosed cases underscore the need for pathologists to be alert to incomplete sections of prostate cores.Objective To investigate the validation and reliability of Istanbul Low Back Pain Disability Index (ILBPDI) in axial spondyloarthritis (Ax-SpA).Methods Patients with Ax-SpA according to The Assessment of SpondyloArthritis International Society criteria were recruited. The validation was assessed by face, content, and construct (convergent and divergent) validities, whereas the reliability was assessed by internal consistency and test-retest reliability. Factor analysis was performed. Convergent validity was assessed by correlations of ILBPDI with functional parameters (The Bath Ankylosing Spondylitis Functional Index, The Dougados Functional Index, and The Health Assessment Questionnaire). Divergent validity was assessed by correlations of ILBPDI with non-functional parameters.Results Two hundred forty patients were recruited. Cognitive debriefing showed ILBPDI to be clear, relevant, and comprehensive. Cronbach's alpha coefficient was 0.953. The test-retest reliability was good with the intraclass correlation coefficient of 0.870. ILBPDI was represented by three-factor groups of activity axial bending, sitting/rest, and standing activities. ILBPDI had good correlations with the functional parameters (rho changes between 0.809 and 0.580), and it had poor or non-significant correlations with the non-functional parameters (absolute rho changes between 0.669 and 0.001).Conclusion ILBPDI is a practical, accurate, and non-time-consuming scale which is valid and reliable to evaluate the functional disability in patients with Ax-SpA.B
