Abstract

The purpose of present study is to construct an index which can detect faking responses on the Rorschach test. For this purpose, this study compared the Rorschach responses of normals pretending schizophrenia with those of true patients with schizophrenia focusing on the ratio of dramatic responses variable. And the index constructed in study 1 was applied to the faking group pretending to have PTSD symptoms. This procedure was done to examine the cross validity related to the severity of symptoms. The results are as follows. First, for detecting the subject faking schizophrenia on the Rorschach test, it seems to reasonable to use the following criterion; 'the ratio of dramatic responses over .20 and the ratio of dramatic responses with form quality o over .30'. Second, there may be a better chance of detecting the subject faking PTSD with the criterion; 'the ratio of dramatic responses over .15 and the ratio of dramatic responses with form quality o over .25'. Therefore, in order to detect the faking case, the type and severity of target symptoms that the subject intends to malinger must be considered carefully. Third, the Rorschach Faking Index should be applied with flexibility in clinical settings. Finally, the implications of the results and future research directions are mentioned.
