Mediation models using the PROCESS macro (Model 4) for SPSS were applied to evaluate the pathways linking clinical severity and psychosocial factors to quality-of-life domains.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 120 participants diagnosed with COPD, disease stages were found to be GOLD A: 25.8%, GOLD B: 35.8%, and GOLD E: 38.3%. Clinical severity measures (CAT, mMRC) were moderately correlated with both psychological symptoms and emotion-regulation difficulties (p &amp;lt; 0.05). CAT had a significant indirect adverse effect on physical quality of life via emotion regulation difficulties [b = \u20130.174, 95% CI (\u20130.303, \u20130.069)]. Perceived social support positively predicted physical quality of life via lower depressive symptoms (b = 0.52, 95% CI (0.06, 1.10)). Stress was indirectly associated with poorer psychological quality of life through reduced social support [b = \u20130.191, 95% CI (\u20130.363, \u20130.042)].<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Psychosocial mechanisms substantially contribute to quality-of-life impairment in COPD and operate alongside traditional clinical indicators. Emotion-regulation difficulties and social support emerge as key psychological pathways linking symptom severity and quality-of-life outcomes, suggesting that comprehensive COPD management should
