The objective was to provide psychometric evidence of the 14-item and 10-item version of the Perceived Stress Scale in nursing professionals from Peru.
Data on 2848 professionals (92.275% women) between 23 and 69 years old (M = 21.876; SD = 10.763) was extracted from ENSUSALUD 2015. An exploratory structural equation modelling (ESEM) was applied with Mplus 7.0 software to analyse several measurement models in the PSS: unidimensional, bidimensional, models with method factor, and bifactor. Finally, the reliability was analysed.
The two-factor structure obtained adequate fit indices, and acceptable factorial loadings (>.50), while the unidimensional model has poor statistical support. The construct and score reliability was also adequate.
The two-factor model of the PSS-10 and PSS-14 presents adequate psychometric properties to expand its use to empirical research.
旨在为秘鲁护理专业人员提供感知压力量表 14 项和 10 项版本的心理计量学证据。
从 2015 年 ENSUSALUD 中提取了 2848 名专业人员（92.275%为女性）的数据，年龄在 23 至 69 岁之间（M=21.876；SD=10.763）。使用 Mplus 7.0 软件对 PSS 中的多个测量模型（包括单维、双维、带方法因子的模型和双因子模型）进行了探索性结构方程建模（ESEM）分析。最后，对信度进行了分析。
所获得的两因素结构具有较好的拟合指数和可接受的因子负荷（>.50），而单维模型的统计支持较差。结构和分数的可靠性也足够。
PSS-10 和 PSS-14 的两因素模型具有较好的心理计量学特性，可以将其扩展用于实证研究。
