Stress may relate to an increased risk of psychological and physical disorders. Thus, a brief and efficient measurement instrument for researchers to measure stress is essentially needed.
To assess measurement properties of the validated Chinese version of the Perceived Stress Questionnaire-13 (PSQ-C-13), we conducted a two-wave longitudinal study from September to December, 2021 with a convenient sample of medical students.
A two-factor (constraint and imbalance) structure showed good fit indices (Comparative Fit Index [CFI] = 0.972, Tucker-Lewis Index [TLI] = 0.966, Root Mean Square Error of Approximation [RMSEA] = 0.062). Spearman correlations with the Chinese Perceived Stress Scale-10 illustrated that convergent validity of the PSQ-C-13 was relatively satisfactory ( = 0.678 [baseline], 0.753 [follow-up]). Measurement invariance was supported across subgroups (gender, age, home location, single-child status, monthly households' income, and part-time status) and time points. Internal consistency was sound (Cronbach's α = 0.908 [baseline], 0.922 [follow-up]; McDonald's ω = 0.909 [baseline], 0.923 [follow-up]). Stability between time points was good (Intraclass Correlation Coefficient = 0.834).
The two factors of the PSQ-C-13 including constraint and imbalance may adequately measure the level of stress on participants. The PSQ-C-13 is a convenient and efficient instrument that contains valid and reliable psychometric properties.
压力可能与心理和身体疾病风险增加有关。因此，研究人员迫切需要一种简短有效的压力测量工具。
为评估经过验证的中文版感知压力问卷13（PSQ-C-13）的测量特性，我们于2021年9月至12月对医学生进行了一项方便抽样的两波纵向研究。
两因素（约束和失衡）结构显示出良好的拟合指数（比较拟合指数[CFI]=0.972，塔克-刘易斯指数[TLI]=0.966，近似均方根误差[RMSEA]=0.062）。与中文版感知压力量表10的斯皮尔曼相关性表明，PSQ-C-13的收敛效度相对令人满意（基线时=0.678，随访时=0.753）。在各亚组（性别、年龄、家庭所在地、独生子女状况、家庭月收入和兼职状况）和时间点上均支持测量不变性。内部一致性良好（克朗巴哈α系数=基线时0.908，随访时0.922；麦克唐纳ω系数=基线时0.909，随访时0.923）。时间点之间的稳定性良好（组内相关系数=0.834）。
PSQ-C-13的两个因素（约束和失衡）可能充分测量参与者的压力水平。PSQ-C-13是一种方便有效的工具，具有有效且可靠的心理测量特性。
