This study revised the Chinese version of 11-item circadian-type inventory (CTI-11) and examined its validity and reliability in textile workers. 3833 workers were recruited to complete the Chinese version of CTI-11. The Composite Scale of Morningness (CSM) was used as the concurrent validity instrument. The exploratory factor analysis revealed that the Chinese version of CTI-11 consists of two factors: flexibility/rigidity (FR) and languid/vigorous (LV). The results of confirmatory factor analysis showed that CTI-11 has a good construct validity. Measurement invariance test indicated that the factor structure of CTI-11 is quite stable across gender and work shifts. FR and LV are significantly correlated with CSM, and LV can significantly predict insomnia. The Cronbach’s alpha coefficient of the two subscales were satisfactory. These findings indicated satisfactory psychometric properties of the Chinese version of CTI-11 in a working sample, with the implication that this scale is potentially a reliable assessment tool on individuals’ adaptability to shift work.

本研究修订了中文版的 11 项昼夜节律型清单 (CTI-11)，并检验了其在纺织工人中的效度和信度。招募了3833名工人完成了CTI-11的中文版。晨间综合量表 (CSM) 被用作并发效度工具。探索性因素分析显示，CTI-11中文版由两个因素组成：柔韧性/刚性（FR）和懒惰/活力（LV）。验证性因子分析结果表明CTI-11具有良好的结构效度。测量不变性检验表明，CTI-11 的因子结构在跨性别和工作轮班时相当稳定。FR和LV与CSM显着相关，LV可以显着预测失眠。两个分量表的 Cronbach's alpha 系数均令人满意。
