Does the MMPI-2-RF have an equivalent of the PK scale of the MMPI-2?
The MMPI-2 PK scale has been found to be associated with increased risk for PTSD in combat veterans. However, elevations on this scale are not specific to PTSD. Table 3-16 of the Technical manual shows that scores on PK are highly correlated (approximately .90) with the Higher-Order scale EID (Emotional-Internalizing Dysfunction) and the Restructured Clinical scale RCd (Demoralization). Empirical correlates reported in Appendix A of the Technical Manual indicate that the single best MMPI-2-RF predictor of PTSD symptoms is the Specific Problems scale AXY (Anxiety).
