Accurate and reliable tools are needed to assess disease activity and QoL in different cultural contexts. This study aimed to evaluate the psychometric properties of the Persian versions of the Evaluation of Ankylosing Spondylitis Quality of Life (EASi\u2010QoL) and Ankylosing Spondylitis Disease Activity Score (ASDAS) scales in Iranian AS patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A cross\u2010sectional study was conducted on 70 AS patients referred to a tertiary hospital in Tehran. Patients completed the EASi\u2010QoL, and 39 also completed the ASDAS questionnaire. The translation followed the forward\u2013backward method.

Content validity was evaluated using the content validity ratio (CVR) and Content Validity Index (CVI). Test\u2013retest reliability was examined using Spearman's rank correlation for non\u2010normally distributed data.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The ICC values for EASi\u2010QoL ranged from 0.71 to 0.82, while Spearman's correlation coefficients ranged from 0.63 to 0.80. For ASDAS, all items except Question 1 had ICC and Spearman's correlation coefficients above 0.8, indicating high test\u2013retest reliability. The average CVR for EASi\u2010QoL was 0.56, and for ASDAS it was 0.68. The CVI for relevance, clarity, and simplicity ranged from 0.86 to 0.96 for both scales, confirming good content validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The Persian versions of the EASi\u2010QoL and ASDAS scales demonstrate adequate reliability and validity.
