Reliability and Validity of Self-report Scale of Brief Psychopathological Symptoms / 中国临床心理学杂志

Objective: To examine the reliability and validity of self-report scale of brief psychopathological symptoms(SBPS). Methods: The reliability and validity of the scale were tested based on three groups of subjects, including the cases involved forensic problems, the patients with mental disorders and normal persons. Some of them were retested 5-15 days after first examination. Other subjects of them finished MMPI at the same time. Results: ①The Cronbach's ? coefficients of SBPS was 0.91. The split-half reliability was 0.90. The test-retest reliability ranged from 0.73～0.98. ②The correlations between factors scores and the total scores ranged from 0.79 to 0.87. The correlations among the four factors scores, ranged from 0.50 to 0.65. Significant correlation was found between the total scores of SBPS and the fake scores of MMPI (r =0.76). Based on the experts diagnosis, the accuracy rate of SBPS for evaluating malingering was 86.6%. Conclusion: The SBPS has acceptable psychometrics properties on reliability and validity.

Analysis of Using Binomial Forced-Choice Digit Memory Test in Patients With Financially Compensable Head Trauma / 中国临床心理学杂志

Objective:To study the validity of Binomial Forced-Choice Digit Memory Test(BFDMT) in detecting dissimulation of intellectual deficit.Methods:64 subjects with compensable head injury were assessed by BFDMT,experiential judgment and Raven's Standard Progressive Matrices (RSPM),and were finally diagnosed on intellectual deficit degrees.Results:(1)The rate of malingering was 78.1% judged by BFDMT,and 43.8% by experiential judgment.(2)All of the 16 uncertain cases by experiential judgment were assessed as malingering by BFDMT.(3)Only one case in 64 was considered as a faulted diagnosis by follow-up.Conclusion:BFDMT is useful for detecting dissimulation of intellectual deficit particularly for the difficul cases in clinical experiential judgment.
