One such assessment tool is the Strengths and Difficulties Questionnaire (SDQ), though it has not yet been validated in this specific population. This study aimed to evaluate the reliability, validity, responsiveness, and the minimal clinically important difference (MCID) of the SDQ in this specific population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Following the consensus-based standards for the selection of health measurement instruments (COSMIN) guidelines, we conducted a psychometric evaluation combining cross-sectional and longitudinal designs among 307 adolescents with myopia (including newly diagnosed and follow-up cases). Baseline assessments evaluated feasibility, reliability (internal consistency and test\u2013retest stability), and validity (construct and discriminant validity). Follow-up surveys after myopia correction were used to assess responsiveness and establish the MCID using anchor-based methods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The SDQ demonstrated acceptable internal consistency (Cronbach\u2019s\n                      <jats:italic>\u03b1<\/jats:italic>\n                      \u202f=\u202f0.71) and good test\u2013retest reliability (ICC\u202f=\u202f0.73).

While responsiveness was modest [effect size (ES)\u202f=\u202f\u22120.26, standardized response mean (SRM)\u202f=\u202f\u22120.28], the MCID was determined to range between 2.00\u20132.38 points, with a threshold of 2 points recommended for group-level discrimination.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The SDQ is a reliable and valid tool for assessing psychological well-being in adolescents with myopia.
