Background and purpose: With the improved life expectancy of people living with HIV (PLWH) due to widespread use of antiretroviral therapy (ART), there is a greater emphasis on enhancing long-term well-being and overall quality of life for PLWH. Understanding interpersonal personalities of PLWH can gain further insight into how to improve the overall quality of life in this population. The International Personality Item Pool-Interpersonal Circumplex (IPIP-IPC) scale has been developed to assess interpersonal personalities of individuals, and this scale has been translated into Chinese. However, the Chinese version of IPIP-IPC has not been tested among PLWH in China. In this study, we aimed to test the psychometric properties and circumplex structure of this scale.
Methods: This study was based on cross-sectional, multi-center, large sample data. We employed the Chinese version of IPIP-IPC scale on 3040 PLWH from April 2022 to April 2023 in China to test its psychometric as well as circumplex properties. The structural summary method (SSM) was employed to analyze the circumplex structure of the scale.
Results: The total scale exhibited a Cronbach's alpha of 0.85 and McDonald's omega of 0.91. Out of the 288 possible relationships, 275 relationships satisfy the circular properties hypothesis. The scale demonstrates good reliability and validity, meeting the requirements of psychometrics.
Conclusion: Our findings demonstrate that the Chinese version of the IPIP-IPC scale is a reliable tool for evaluating interpersonal personalities in this population. These results highlight the validity and applicability of the IPIP-IPC scale specifically in the Chinese context, providing valuable insights into the intricacies of interpersonal traits among PLWH.
