Detection Of Malingering:the Reliability And Validity Of Chinese Version Of The Structured Interview Of Reported Symptoms (SIRS CV)

Objective:To examine the reliability and validity of the Chinese version of the Structured Interview of Reported Symptoms (SIRS CV).Methods:In simulation design,40patients with schizophrenia, mood disorder, and other psychiatric disorders,120normal undergraduate students[honest group(n=40), coached simulators(n=40) and uncoached simulators(n=40)], and in known-group design,100patients in a forensic clinic [suspected malingering group (n=20) and non-malingering group (n=80)] were investigated with (SIRS CV) in this research.80normal undergraduate students were also assessed with Minnesota Multiphasic Personality Inventory-2(MMPI-2). The consistency of the scale was tested by using correlation analysis and Cronbach a coefficient. The criterion was the three validity scales [Lie (L), Infrequency (F), Correction (K)] of the MMPI-2. The score of the Chinese version of SIRS difference in different groups was used to test the validate validity.Results:The Cronbach a coefficient were0.70-0.89. The malingering dimension(including8factor) scores of (SIRS CV) were significantly positive associated with the "F" score of MMPI-2(r=0.30-0.74, P<0.05); and significantly negative associated with the "L" and "K" of MMPI-2(r=-0.22～-0.53, P<0.05). The13factor scores of SIRS CV in uncoached simulators were significantly higher than normal group and coached simulators,[ie., Rare symptoms RS(10.2±3.3) vs.(0.7±1.3),(8.8±3.1)].The scale factor scores of SIRS CV in suspected malingering group scores were significantly higher than non-malingering group and general psychiatric patients [ie., Rare symptoms RS (7.6±1.8) vs.(2.5±3.2),(2.4±1.9), P<0.05)]. The sensitivity and specificity of these two studies was60%/95%, and92.5%/94.37%.Conclusion:The Chinese version of the Structured Interview of Reported Symptoms is a reliable and valid measure for identification of malingering in actual work.
