The Ten-Item Personality Inventory (TIPI) was designed as a brief instrument of the Big Five personality traits. This study aimed to explore the internal consistency and structural validity of the Chinese version of TIPI (TIPI-C) in medical college students.
A cross-sectional study was conducted in 11 provinces of China. Spearman-Brown coefficient, standardized Cronbach's α coefficient, and Cronbach's α coefficient were applied to estimate the internal consistency. Spearman-Brown coefficient was applied to estimate split-half reliability. Principal components analysis (PCA) and confirmatory factor analysis (CFA) were used to identify the structural validity.
A total of 2223 medical college students recruited from different regions of China were included. The Spearman-Brown coefficients of TIPI-C ranged from 0.129 to 0.786 and the Cronbach's α coefficients ranged from 0.119 to 0.785. The split-half reliability of the Spearman-Brown coefficient was 0.508. The latent structure of Extraversion, Emotional Stability, and Conscientiousness complied with the intended structure, and the internal consistency coefficients of these three traits were supported. However, the internal consistency coefficients of Agreeableness and Openness were low and the structural validity was not supported.
TIPI-C primarily stands out as a feasible instrument for brief measurements of the Extraversion, Emotional Stability, and Conscientiousness domains. Further research is required to evaluate the concurrent validity and the test-retest reliability of TIPI-C in different populations and potentially modify the instrument to be more suitable for the Chinese population.
十项人格量表（TIPI）被设计为一种测量大五人格特质的简短工具。本研究旨在探讨中文版TIPI（TIPI-C）在医学生中的内部一致性和结构效度。
在中国11个省份进行了一项横断面研究。采用斯皮尔曼-布朗系数、标准化克朗巴哈α系数和克朗巴哈α系数来估计内部一致性。应用斯皮尔曼-布朗系数来估计分半信度。采用主成分分析（PCA）和验证性因素分析（CFA）来确定结构效度。
共纳入了来自中国不同地区的2223名医学生。TIPI-C的斯皮尔曼-布朗系数范围为0.129至0.786，克朗巴哈α系数范围为0.119至0.785。斯皮尔曼-布朗系数的分半信度为0.508。外向性、情绪稳定性和尽责性的潜在结构符合预期结构，这三个特质的内部一致性系数得到了支持。然而，宜人性和开放性的内部一致性系数较低，且结构效度未得到支持。
TIPI-C主要是一种用于简短测量外向性、情绪稳定性和尽责性领域的可行工具。需要进一步研究来评估TIPI-C在不同人群中的同时效度和重测信度，并可能对该工具进行修改，使其更适合中国人群。
