In study one, criterion validity of this scale was supported by its significantly positive correlation with the MMPI-2 (r = 0.282 ~ 0.481 for Infrequency), and by its significantly negative correlation with the MMPI-2 (r = -0.255 ~ -0.519 for Lie and -0.205 ~ 0.391 for Correction). The Chinese Version of SIRS-2 demonstrated satisfactory internal consistency in both study one and two. In Study two, with a known-groups comparison design, scales scores for feigning symptoms were compared between 20 suspected malingerers and 80 psychiatric outpatients from two forensic centers using the Chinese Version of SIRS-2. Minnesota Multiphasic Personality Inventory-2(MMPI-2) was administered in 80 undergraduate students. Scales scores for feigning symptoms among three groups were carried out for discriminant validity of the Chinese Version of SIRS-2.
40 students asked to reply to questions honestly. 40 students asked to simulate symptoms of mental illness b. In Study one, with a simulation design, the subjects included a. Two studies were conducted to evaluate the reliability and validity of the Chinese Version of SIRS-2. The aim of the study was to examine the reliability and validity of the Chinese version of this scale. The Structured Interview of Reported Symptoms-2 (SIRS-2) was designed to assess the feigned symptoms in both clinical and non-clinical subjects. Malingering detection has emerged as an important issue in clinical and forensic settings.
