Such comorbidity is related to worse outcomes in both disorders. Subsyndromal features of BPD are also common in depression. However, studies of simultaneous changes in BPD and depression severities are scarce, and their interactions are poorly understood.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Aims<\/jats:title>\n                <jats:p>Studying the associations between changes in BPD and depression symptoms over the course of an MDE.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>In a 6-month naturalistic cohort study of MDE\/BPD, MDE\/MDD, and MDE\/BD patients (<jats:italic>N<\/jats:italic>\u2009=\u200995), we measured change in BPD features between baseline and six months with the Borderline Personality Disorder Severity Index (BPDSI), an interviewer-rated instrument quantifying recent temporal frequency of BPD symptoms.

These were similar in all diagnostic groups. In multivariate regression models, changes in depression severity independently associated with changes in symptoms in the BDSI.
