Reliability and validity of a Japanese short version of the Inventory of Interpersonal Problems

要旨

The purpose of this research was to develop a Japanese short version of the Inventory of Interpersonal Problems (IIP) and examine its reliability and validity. In Study 1, we developed a short version of the IIP using item response theory (IRT). The results indicated sufficient measurement accuracy for the short version compared to the original IIP and an existing short version (IIP-32). Specifically, the short version had better measurement accuracy for participants with higher levels of interpersonal problems. Similar to previous research, confirmatory factor analysis demonstrated the factor structure and circumplex structure. In Study 2, we examined the reliability and validity of the short version. The results revealed good internal consistency and test-retest reliability. Furthermore, the short version correlated with depression, state anxiety, eating disorder tendency, psychological symptoms, self-esteem, and personality. Finally, the application of the short version in counseling situations is discussed.
