A deficit in emotion regulation is thought to be a trans-diagnostic factor of several mental disorders and is mostly assessed by using self-report measures. Comparing values and results cross-nationally presupposes that these scores are based on the invariance of psychometric properties. The present study aims to compare the psychometric properties and the factorial invariance of the Emotional-Dysregulation-Scale (ED-Scale) cross-nationally. Analyses were based on data of treatment-seeking Canadian and German clinical samples (n= 144; n= 115). They were diagnosed using structured clinical interviews and completed self-report measures. We calculated reliability and validity indices. In order to determine the factorial invariance (configural, metric, scalar, and residual invariance), we conducted several multi-group confirmatory factor analyses. For both samples, Cronbach's αs proved to be excellent. Convergent, divergent and discriminant validity were supported. Comparing increasingly stringent models, tests of measurement invariance indicated at least partial measurement invariance. These findings suggest that the ED-Scale operates in a similar fashion among English and German-speaking clinical samples. Therefore, we conclude that the psychometric properties of the ED-Scale are appropriate and that results can be compared cross-nationally. Future research should examine the measurement invariance in different cultures and ethnic minority groups.
