The symptom checklist-27-plus has demonstrated good psychometric properties in various samples, but clinical data have not yet been published. Data from 690 mostly young female patients with eating disorders show reliabilities ranging from acceptable to very good (Cronbachs α between 0.76 und 0.89). Data from intake and discharge show a good ability to measure change (Cohen's d between 0.27 und 1.31). At intake, patients display a very high symptom load, which has decreased significantly at discharge.
