## Contribution

The paper introduces a novel theoretical model and validated questionnaire for understanding Xin as a multidimensional personality construct in Chinese culture.

## Key findings

- A five-dimensional model of Xin was developed through interviews and validated with strong psychometric properties.
- Xin is most strongly associated with relational connectivity and varies significantly by gender, education, and ethnicity.
- The questionnaire demonstrates good reliability and validity for measuring Xin across different cultural and demographic contexts.

## Abstract

This study investigates the multifaceted construct of
Xin
(“信”) within Chinese culture, reconceptualizing it as a core personality quality that extends beyond mere honesty or trustworthiness.

Employing a mixed-methods approach, we integrated grounded theory and quantitative scale development to articulate the structure of
Xin
and its psychological significance. Three sequential studies were conducted: (1) Through in-depth interviews with 22 Chinese participants, a five-dimensional model of Xin was constructed, comprising relational domains between humans and heaven and earth, humans and social culture, the self, individual archetypes, and connective integration. (2) A corresponding questionnaire was developed and validated via exploratory factor analysis (Sample 1, N = 231) and confirmatory factor analysis (Sample 2, N = 814), confirming the five-factor structure. (3) The questionnaire was administered to a broader sample (Sample 3, N = 807) to assess recognition and identification levels across these dimensions..

Study 1 established a five-dimensional model of Xin. Study 2 confirmed this structure via EFA and CFA, with good psychometric properties (α = .951–.954; CFI = .913, RMSEA = .051). Study 3 showed that Xin is perceived most strongly in relational connectivity and least in archetypal manifestations, with significant variations by gender, education, and ethnicity.

These findings illuminate Xin as a complex personality construct integral to Chinese cultural identity and personal development, offering insights for its cultivation in psychological practice and everyday life.
