Issues to Consider Prior to Using the R-PAS in a Forensic Context.

After the sudden death of John Exner (developer of the Comprehensive System; CS; Exner, 1969, 2003), a new scoring system, the Rorschach Performance Assessment System (R-PAS; Meyer, Viglione, Mihura, Erard, & Edberg, 2011) was introduced. While the CS was developed with extensive research over approximately 40 years, this new system has only been studied for approximately fifteen years. When considering its forensic usage, it is essential to understand that CS validity research does not translate directly to R-PAS. One primary reason for the lack of translation is the differing administration procedures. Other factors such as the absence of comparison descriptive group data (non-patient, clinical, & forensic) and internal validity problems with studies utilized in the primary meta-analyses which supports the R-PAS variable selection should be considered in determining the methods admissibility. In this article, we discuss essential issues to consider prior to using the R-PAS in an applied context. [ABSTRACT FROM AUTHOR]
