[Symptom Validation in Independent Medical Evaluations].

High prevalence rates of non-authentic complaints identified by experts in the field of insurance medicine draw attention to the risk of services, which are of limited availability and financially compensated, being used in ways that are not goal-oriented. Therefore, symptom validity testing has become a growing issue to prevent non-targeted monetary compensations. This paper outlines the best-evaluated methods and instruments. Based on the data currently available, their validity, in particular in the context of medico-legal assessment, is assessed. It is concluded that symptom validity assessment allows inferences about the degree of certainty of clinical judgements on the authenticity of reported symptoms. Thus, the application of the suggested instruments enhances significantly the quality of medical and psychological expertise. However, the integration of the additional results into the overall assessment is challenging and needs to be further clarified.
