However, lesion characteristics alone cannot fully explain the complexity of endometriosis-related pain. Pain catastrophizing, a cognitive process that influences pain perception, has traditionally been studied through cross-sectional or 2-wave designs, which struggle to capture its dynamic interplay with endometriosis pain. To address these gaps, our study explores the bidirectional relationship between pain catastrophizing and pain outcomes\u2014including intensity, frequency, and flares\u2014over a detailed 4-week period and an aggregated 30-day time frame and across sensory and affective dimensions.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>A latent growth curve model assessed the relationship between pain catastrophizing, initial pain levels, and endometriosis pain trajectories over 4 weeks. Additionally, 4 mediator models explored how baseline pain catastrophizing affects various pain aspects, including sensory and affective dimensions, and its subsequent influence on pain catastrophizing.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Results indicate that high levels of pain catastrophizing significantly escalate endometriosis pain over 4 weeks, affecting average pain intensity, episode frequency, and flares over 30\u2009days. Pain catastrophizing also adversely impacts sensory and affective dimensions. These elements partially mediate baseline pain catastrophizing\u2019s effect on week 5 levels, revealing a bidirectional relationship. Notably, whereas the affective dimension amplifies subsequent pain catastrophizing, the sensory dimension exerts a contrasting negative association.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The study highlights the bidirectional influence between pain catastrophizing and several aspects of endometriosis-related pain.
