Applicability of the Chinese Beck Depression Inventory.

Using a sample of 329 currently depressed patients from 24 hospitals across China, this study assesses the reliability and validity of the Chinese version of Beck Depression Inventory (CBDI). Even though the internal reliability and the concurrent validity were good (Cronbach alpha = 0.846; r = 0.566), the results showed that the item of Loss of Libido was most weakly correlated with the CBDI's total score; the items of Sense of Punishment, Sense of Hate, Self Accusations, Crying Spells, Irritability, and Somatic Preoccupation were poorly associated with the intensity of depression measured by the total score of the Chinese version of Hamilton Depression Rating Scale (CHDS). The CBDI's construct validity was rather poor by principal component analysis: three of six factors were unexplainable in terms of clinical features of depression. The results demonstrated that CBDI, even though it was semantically translated into Chinese language, still could not be effectively applied in clinic and research settings in China. Using the theory and methods of psychometrics to develop China's own culturally sensitive self-report inventory is the correct way to eliminate cultural bias and make cross-cultural research more valid. This is the most rigorous scientific approach to cross-cultural comparisons.
