Somewhat similar to the MMPI-2, the MMPI-A includes a 66-iteIn F scale that is di- vided into FI and F2 subscales. The Fl scale is composed of 33 items, all of which appear on the first half (initial 236 items) of the MMPI-.A. booklet, and relates to the standard clinical scales. In contrast, the 33-item F2 scale is composed of items on the last half of the booklet (final 114 items) and relates to the supplementary and clinical scales. The Fl and F2 scales can be interpreted in much the same way as for F and Fb on the M.MPI-2. The optimal cutoff score for Fb (and PI and F2) is not known. As a result, it is recommended that the same guidelines and T scores used to determine an invalid profile for F also be used for Fb (and PI and F2). However, the Fb scale has not been found to be as effective a predictor of malingering as the F scale (Iverson et al., 1995).
