Abstract
GARCIA SILGO, Mónica. Mental disorder malingering detection with MMPI-2-RF, PAI and SIMS in a military analog design. Sanid. Mil. [online]. 2019, vol.75, n.4, pp.203-213. Epub June 22, 2020. ISSN 1887-8571. https://dx.doi.org/10.4321/s1887-85712019000400004.
The studies in military malingering have always been increased in war times, but it's not until World War II when the first evidenced based studies arise. Since then, hundreds of studies have been done with different diagnostic tests to determine the classification capacity of their detection scales. Among the tests with more evidence demonstrated are The Minnesota Multiphasic Personality Inventory (MMPI), The Personality Assessment Inventory (PAI) and The Structured Inventory of Malingered Symptomatology (SIMS).
Objective:
To analyze the classification capacity of the Spanish version of MMPI-2-RF, PAI and SIMS in a Spanish military sample (N = 342) -naive in psychopathology, either in malingering scales-.
Method:
An analog design was used with control group (n = 95), analog group of general psychopathology (n = 70), analog group of depression (n = 90) and analog group of anxiety (n = 87). Data analysis was done with Statistical Package SPSS 19.0 and there were used Chi-Square Pearson, One-way ANOVA, One-way ANCOVA, Eta squared, Bonferroni and Cohen's d.
Results:
All the scales of the three instruments were higher scores in analog groups than in control, except those that measure positive impresion, where these three groups were below. In addition, all malingering scales of the three tests differ between control group and analog groups. The best detection scales were for the MMPI-2-RF: F-r, Fs, FBS-r and Fp-r, in this order; for the PAI: NIM, MAL and RDF, in this order; and for the SIMS: Af and Total, in this order.
Conclusions:
MMPI-2-RF, PAI and SIMS are good instruments to discriminate between control and analog fakers.
