Note. N = 209 for analyses of the M-FAST; n = 171 for analyses of the SIMS. The M-FAST cut-score of 6 is recommended in the manual while scores of 8 and 16 have been described in the literature (see introduction). The SIMS cut-score of 14 is recommended in the measure’s manual, and differential sensitivity and specificity at cut-scores of 13 and 16 are also described in the manual; a cut-score of 44 has been evaluated in prior published research (see introduction). M-FAST = Miller Forensic Assessment of Symptoms Test (Miller, 2001); SIMS = Structured Interview of Malingered Symptomatology (SIMS; Widows & Smith, 2005; Smith & Burger, 1997).
