However, correlations between pain intensity and psychological distress are generally weak, suggesting a more complex relationship. Although evidence indicates a bidirectional association, the role of potential mediators warrants further study. The aim of this cross-sectional registry study was to explore mediators of the relationship between pain intensity and psychological distress, and vice versa, among individuals with chronic\u00a0pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_sjpain-2026-0030_abs_002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This cross-sectional cohort study included 6,497 adult chronic non-cancer pain patients from the Swedish Quality Registry for Pain Rehabilitation (SQRP) with Patient-Reported Outcome Measures (PROMs) data (2008\u20132016). Five potential mediators\u00a0\u2013\u00a0catastrophizing, fear-avoidance, physical activity level, acceptance and insomnia\u00a0\u2013\u00a0were examined in the bidirectional relationship between pain intensity and psychological distress using Partial Least Squares Structural Equation\u00a0Modelling (PLS-SEM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_sjpain-2026-0030_abs_003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The direct paths (i.e.,\u00a0correlations) between pain intensity and psychological distress in both directions became non-significant when controlling for the five mediators.
