Psychometrics of the Chinese Inventory of Personality Organization (IPO-CH)

The present study aimed to examine the psychometric properties of the Chinese Inventory of Personality Organization (IPO-CH). The IPO-CH was administered to a sample of 336 Chinese undergraduates, and, among them, 125 participants completed the survey 2 months later. Results showed that the IPO-CH has adequate internal consistency (Cronbach's α = .95) and test-retest reliability (r = .60). Exploratory factor analysis did not replicate the original five-factor model but suggested a four-factor model. The IPO-CH manifested good concurrent validity and convergent validity concerning the severity of the pathological personality disorder symptoms. Furthermore, the IPO-CH predicted participants' depression severity and life events evaluated 2 months later. Future research may need to evaluate its properties in Chinese clinical samples.
