Psychometric properties of the BSL-23 (English translation) and its equivalency with the BSL-23 (German): an analysis based on Item Response Theory

Although widely employed in clinical research, no studies have evaluated the psychometric properties of the English version of the Borderline Symptom List-23 (BSL-23), including the equivalence of its mean score to that of the German version.

Zusammenfassung:Although widely employed in clinical research, no studies have evaluated the psychometric properties of the English version of the Borderline Symptom List-23 (BSL-23), including the equivalence of its mean score to that of the German version.
