The Study Of The Depression Index (DEPI) And Coping Deficit Index (CDI) In Rorschach Test

Exner has set up a comprehensive system in Rorschach test in 1970s, and depression index was used to assess depression. But some studies show that the depression index has controversy in the diagnostic validity and the problem of lower sensitivity.Coping Deficit Index is generated in the process of revision on the DEPI. and from the third type of depression:depression, helpless-type. Therefore, it can be considered as a diagnosis of depression in secondary data sources.This study are used two groups of subjects, including depression group and control group 30 people, both psychological test and questionnaires to test the scorer reliability, empirical validity diagnostic accuracy of the depression index and coping deficit index and incremental validity. The scorer reliability examine mainly through Kappa coefficient; empirical validity examine mainly through the Pearson correlation between the DEPl,CDI and SDS. and the t test between depression group and control group; incremental validity examine mainly through Binary Logistic Regression Analyses.The results of this study shown that:(1) The Kappa coefficient of Rorschach depression index and coping deficit index is acceptable (above 0.7). The Kappa coefficient of DEPI is 0.845;and CDI is 0.906.(2) The Pearson correlation between the DEPl,CDI and SDS is 0.400 and 0.312.and is significant level; T test results between depression group and normal group showed that DEPI and CDI in depression group were significantly higher than the normal group;(3) When DEPI was used to the diagnostic criteria, diagnostic accuracy was 40%; When CDI was used to the diagnostic criteria, diagnostic accuracy was 56.7%.(4) CDI can bring some incremental validity, and increase the diagnostic accuracy of DEPI.
