Objective:
This study synthesized the results of 22 studies (N = 3,912) of feigned posttraumatic stress disorder (PTSD) symptoms that used the Minnesota Multiphasic Personality Inventory-2 (MMPI-2).
Method:
Robust variance estimation was used to analyze variables that affected the accuracy of scales used to detect feigned symptoms.
Results:
The FB scale (g = 1.60), the Obvious-Subtle scale (g = 1.57), and the Gough Dissimulation Index (F-K; g = 1.56) produced very large effect sizes after controlling for study design. Large and significant effect sizes were also observed for the F scale (g = 1.46), the FP scale (g = 1.43), and the Ds scale (g = 1.39).
Conclusions:
The findings of this study suggest that the MMPI-2 validity scales are useful for identifying individuals who are exaggerating or fabricating psychological symptoms. However, there were differences across validity scales and study designs, with some scales demonstrating stronger performances than others.
