Title	Evaluation of the ecst-r atp scales: detecting coached diagnostic-specific feigning and coached feigning of incompetency to stand trial, with comparison to the m-fast
Abstract	The current study used a simulated design to evaluate the performance of the ECST-R ATP Scales with undergraduate participants who were coached using information readily found on the internet to feign incompetency, schizophrenia or both. This study was largely exploratory in nature, but sought to determine if the ATP Scales would be effective when identifying participants with different feigning motivations. The present study also compared the performance of the ATP Scales to the M-FAST in terms of the ability to screen for potential feigning in the aforementioned groups of participants to investigate whether the ATP Scales are more effective in identifying feigning among CST examinees, particularly those feigning incompetency, than a screening measure constructed to identify only feigned psychopathology. The results of the current study suggest that there may be some increased utility of the ATP Scales when identifying feigning of incompetency to stand trial; however, the demonstrated specificity was particularly low leading to concerns regarding clinical utility. It is suspected, however, that the results of the current study relevant to the ATP scales may have been impacted by the utilization of undergraduate participants and their likely less extensive exposure to the courtroom as compared to forensic samples such as genuine CST examinees.
