Standardized Evaluation of Candidates Before Liver Transplantation With the Transplant Evaluation Rating Scale.
The Transplant Evaluation Rating Scale (TERS) was developed to provide a standardized evaluation of the psychosocial functioning of patients, before transplantation. Yet, the first 2 items of the TERS are based on psychiatric diagnoses referring to Diagnostic and Statistical Manual (DSM)-III-R, which leads to a duplication of disorder-specific and symptom-specific contents, that makes it complex to rate. Moreover, the TERS has not been updated to DSM revisions and DSM is not used for the official clinical routine documentation in several European countries.



The objective of this study was, therefore, to investigate the psychometric properties of a diagnoses-corrected version of the TERS (items 1 and 2 omitted).



In 85 patients awaiting liver transplantation, the discrimination capacities, predictive value, convergent validity, and interrater reliability of the original version (TERS10) and the diagnoses-corrected version (TERS8) were analyzed.



In both versions, patients with psychiatric diagnoses (69.4%) exhibited significantly higher TERS mean values than patients without psychiatric disorders. This also held for patients who were temporarily not found eligible for transplantation in the psychosocial evaluation (25.9%) compared with patients who were eligible for listing for transplantation. Furthermore, the area under the curve was >0.90 for both versions and a cutoff of 32.25 is suggested for TERS8 (sensitivity of 90.9% and specificity of 87.3%).



Our results substantiate good psychometric properties of the revised (diagnoses corrected) TERS, which is of great benefit for standardized psychosocial evaluation before liver transplantation. Further, validation of TERS8 and its cutoff in other samples of (liver) transplantation patients is needed.
