BLASCO SAIZ, Juan Luís  and  PALLARDO DURA, Laura. Symptom exaggeration detection by the SIMS and the MMPI-2-RF in patients diagnosed of mixed anxiety-depressive disorder and adjustment disorder in the medico-legal context: a preliminary study. Clínica y Salud [online]. 2013, vol.24, n.3, pp.177-183. ISSN 2174-0550.  https://dx.doi.org/10.5093/cl2013a19.

The aim of this preliminary study is to find a symptom exaggeration pattern in patients diagnosed of mixed anxiety-depressive disorder and adjustment disorder in the medico-legal context. Overall sample (n = 26) was divided in two groups: bona fide patients (n = 12) and suspected of malingering patients (n = 14). The Spanish adaptations of the Structured Inventory of Malingered Symptomatology (SIMS) and the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) were administered to all participants. Regarding the SIMS scores, the best discriminant scales found between groups were Total scale, Neurological Impairment (NI), Amnesic Disorders (AM), and Affective Disorders (AF) scales. Regarding the MMPI-2-RF scores, the best discriminant validity scales were, in order, Fs, Fp-r, F-r and FBS-r, and the best discriminant substantive scales were those regarding somatic complaints (RC1, HPC, NUC, and COG), thought disorders (THD, RC8, and PSYC-r), and mood disorders (Rcd and ACT). Results support the use of both SIMS and MMPI-2-RF as a convergent source of information for the detection of symptom exaggeration in mixed anxiety-depressive disorder and adjustment disorder in the medico-legal context.
