The Panic Disorder Severity Scale\u2014Self\u2010Report (PDSS\u2010SR) is widely used for this purpose. The present study aimed to evaluate the validity, reliability, and optimal cut\u2010off point of the PDSS\u2010SR in an Iranian sample.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>Following a descriptive design, the clinical group of the sample consisted of 45 clinical patients diagnosed with PD (75.6% female), with a mean age of 34.04 years (standard deviation [SD]\u00a0=\u00a012.17) in Tehran in 2023 and 2024 referred to psychotherapy clinics, along with 18 non\u2010PD individuals for the comparison group (83.3% female), with an average age of 31.17 (SD\u00a0=\u00a07.94). Data were analyzed using confirmatory factor analysis, correlation matrices, reliability coefficients, receiver operating characteristic (ROC) curves, sensitivity, specificity, and the estimation of cut\u2010off points.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The construct validity of the PDSS\u2010SR was confirmed through CFA, with adequate goodness\u2010of\u2010fit for the PDSS\u2010SR single\u2010factor structure. By calculating the correlation of PDSS\u2010SR scores with scores on anxiety\u2010related scales, convergent validity was obtained on average. The sensitivity and specificity obtained from the PDSS\u2010SR identified the optimal cut\u2010off point of 6.500 (area under curve [AUC]\u00a0=\u00a00.78), with sensitivity (90.70%) and specificity (61.11%) based on the Youden index. Reliability was obtained by calculating Cronbach's alpha, McDonald's omega, test\u2013retest correlation coefficient, and intraclass correlation coefficient (ICC) as 0.864, 0.861, 0.716, and 0.864, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This research found that the PDSS\u2010SR had sufficient reliability, moderate convergent validity, and good construct validity in Iranian samples, with an optimal cut\u2010off point of 6.50.
