The aim of the current study was to analyze the factor structure and validity of DERS and two of its short\u2010forms (DERS\u2010SF and DERS\u201018), their relation to PD features and personality functioning, gender differences, and the overlap between concepts of alexithymia and emotion regulation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>\n                      Data were extracted from a multi\u2010site clinical sample of patients with PDs or personality related problems referred to specialist mental health services (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20092093). Confirmatory factor analyses (CFA)\u2014specifically first\u2010order correlated and bifactor analysis, as well as analysis of measurement invariance\u2014were applied. Linear associations and group differences were investigated by correlational analysis and independent samples t\u2010tests. DERS and its shortforms were validated through associations with PD features (PD criteria), measures of personality functioning (LPFS\u2010BF), and alexithymia (TAS\u201020).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>CFA of the short forms revealed good model fit, while the full version of DERS showed poorer fit. None of the bifactor analyses supported a strong general factor.
