摘要

This study aims to investigate the psychometric properties and measurement invariance of the Chinese version of the Perth Alexithymia Questionnaire (PAQ) in a Chinese university student population (n = 740). Firstly, the confirmatory factor analysis results replicate the original bifactor model, including a broad general alexithymia factor, and five narrow factors are negative-difficulty identifying feelings (N-DIF), positive-difficulty identifying feelings (P-DIF), negative-difficulty describing feelings (N-DDF), positive-difficulty describing feelings (P-DDF), and general-externally oriented thinking (G-EOT). Secondly, the measurement invariance of the PAQ was confirmed across different genders, two time points, and different age groups. Finally, the internal consistency coefficients for the dimensions of N-DIF, P-DIF, N-DDF, P-DDF, and G-EOT were good, with Cronbach’s α values of 0.874 to 0.895. The test-retest reliability of the five dimensions and the total scale after a 6-week interval showed a moderate level of correlation, with correlation coefficient values of 0.518 to 0.610. In addition, it also showed good criterion-related validity. It can be concluded that the Chinese PAQ is a valid measure for assessing levels of alexithymia in Chinese university students.
