Improvements in the M test as a screening measure for malingering.
Recent studies of the M have failed to confirm its effectiveness as a screening measure for malingering. The present study involved a further analysis of 99 cases reported by Gillis et al. and the construction of Rule-Out and Rule-In scales. Both scales evidence excellent internal reliability, and their combined use was effective in accurately screening greater than 80 percent of potential malingerers.
