Childhood trauma is a key environmental risk factor associated with a more severe course of BD, as it influences its onset, progression, and clinical presentation. To date, no studies have specifically investigated the relationship between lifetime childhood trauma and lifetime MxD in individuals with BD. The aim of our study was to address this gap in a large and well\u2010characterized sample of patients with BD type I and type II.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 376 individuals, 220 euthymic outpatients with BD (MxD =\u2009100, non\u2010MxD\u00a0=\u2009120) and 156 healthy controls (HC), were enrolled. Childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Lifetime MxD was identified according to the Koukopoulos criteria. The relationship between childhood trauma and MxD was evaluated using two different multivariate models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The first model (Wilks' Lambda\u2009=\u20090.834,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) revealed that BD patients with lifetime MxD reported significantly higher CTQ total scores compared to both non\u2010MxD (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.029) and HC (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
