- Abstract
- Objective : We investigated whether Posttraumatic stress disorder patients have a higher tendency to exaggerate the extent of their psychological symptoms compared to other psychiatric patients.
Methods : Medical records of patients, who had received psychiatric treatment at four university hospitals in Korea between January 2009 and December 2010, were retrospectively reviewed. We compared a group of 37 patients diagnosed with PTSD, and another group of 41 patients diagnosed with neurotic, stress-related and somatoform disorders according to the ICD-10. To compare the extent of malingering in the two groups, we compared the validity scales of MMPI-2 and Personality Assessment Inventory. We determined the number of participants in both groups feigning their responses by using various cutoff scores of the validity indicators.
Results : The PTSD group showed significantly higher scores on the F (p=0.001), F (B)(p=0.000), F (P)(p=0.030), F-K (p=0.003) scale of the MMPI-2 compared to the other group of psychiatric patients. The PT-SD group had a significantly higher NIM score (p=0.001) but a lower PIM score (p=0.020) of the PAI compared to the other group of psychiatric patients. Using the cutoff scores, the PTSD group showed a significantly higher number of patients who feigned responses compared to the other group (Fb≥75 (p=0.010), F-K ≥1 (p=0.005), F-K≥10 (p=0.011) from the MMPI-2, and NIM≥80 (p=0.001) from the PAI).
Conclusion : These results suggest that PTSD patients have a tendency to exaggerate their symptom. This group of patients overreported the severity of their condition during standardized personality assessment that included the MMPI-2 or PAI compared to patients diagnosed with other psychiatric disorders. Additional research is required to determine the factors influencing symptom exaggeration in PTSD.
