The ED\u201015 also demonstrated strong internal consistency and test\u2013retest reliability. In subsamples, there was preliminary evidence of measurement invariance across gender, time, country, and to a lesser extent age group. Correlations supported good concurrent validity with eating disorder pathology and eating\u2010related impairment, while convergent validity was mixed, with moderate associations with psychological distress and maladaptive perfectionism, but weak or negligible associations with personal standards perfectionism and autism\u2010related traits. Receiver operating characteristic analyses deriving an optimal diagnostic cut\u2010off indicated good discriminative validity, with the ED\u201015 discriminating probable eating disorder caseness.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Findings add to the growing evidence on the ED\u201015's latent structure and provide preliminary support for measurement invariance, supporting its use as a brief, psychometrically sound tool in routine clinical practice.
