Symptom validity in expert assessment of mental disorders - Prevalence rate of negative-response bias and validation of a German translation of the Structured lnterview of Reported Symptoms (SIRS)

Project No. FF-FR 0223

Status:

ongoing

Aims:

The first sub-project focuses on the retrospective base rate estimation of malingering in psychological expert evaluations and a review of the used criteria. The expert ratings will be compared with scientific recommended indicators. The value of available symptom validity tests (SVT) in Germany, especially for mental disorders, does not correspond to available English state of the art instruments.

Therefore, in the second sub-project a German Version of the SIRS will be validated and its practicability will be tested. The classification rating of the SIRS will be evaluated and compared with the value of conventional SVT.

Activities/Methods:

A German forward-backward translation of the SIRS was done and will be evaluated in patients with mental disorders (n=100) using a between-subjects simulation design. Additionally, conventional symptom validity tests (SIMS, WMT) will be assessed to evaluate their converging and discriminating aspects. Furthermore, a retrospective analysis of psychological expert evaluations from 2002 to 2013 (ca. n=1000) will be performed. The base rate of possible malingering and its indicators will be assessed and reviewed.
