The AUC (area under curve) values of ROC analysis were determined, in order to detect the validity of differentiating of M-FAST and some subscales (AUC for total M-FAST=.
This cut-off value is preferred, as by the original Miller article of the M-FAST scale, where to detect true positives rather than true negatives were taken into consideration.
A moderately significant association between the quantitative scores of M-FAST and MMPI validity scales (F F-K) was detected with Spearman test (M-FAST vs MMPI F: [r.
The importance of this study is to be the first one investigating the reliability and validity of a scale used to detect malingering in Turkey M-FAST scale has been translated to Turkish and M-FAST Turkish Form validity and reliability procedure has been done with this study
M-FAST has a considerably high reliability coefficient as a whole.
001 with test-retest that done in l-3 weeks interval in the developmental study of M-FAST Scale (14).
In the present study, one researcher explicated the diagnosis of malingering, while another researcher, blinded in terms of the clinical features and forensic admission types of the evaluees, applied M-FAST In this way, a single blind study design was planned and the diagnosis of the clinician was considered as the gold standard.
Miller found the area under the curve for M-FAST as .
The M-FAST scores of seven participants were high, although they were not diagnosed to be malingering (the mean M-FAST score of the false positive participants=10.
A moderate correlation was detected between M-FAST total scores and F scale and F-K index quantitative values.
The findings of this study show that, M-FAST Turkish Form represents the structure of the original scale and it is valid and reliable.
Examining the use of the M-FAST with criminal defendants incompetent to stand trial.
