Stress is a public health disease that is increasing rapidly in the population worldwide, so it is necessary to take measures for detection and evaluation, through short scales. The purpose of the study was to analyze the psychometric properties of the Perceived Stress Scale (PSS) in a sample made up of 752 people with an age range of 18 to 62 years (M = 30.18, DE = 10.175), of whom 44% (331) were women and 56% (421) men, from Lima, Peru. The results, by means of confirmatory factor analysis and the Rasch model, confirmed the global adjustment of a 12-item (PSS-12) version with the presence of two orthogonal factors independent of each other, and also demonstrated the metric equivalence according to gender and adequate internal consistency. These results allow us to recommend the use of the PSS-12 in the Peruvian population for the measurement of stress.
压力是一种在全球范围内发病率迅速上升的公共卫生疾病，因此有必要通过简短量表采取措施进行检测和评估。本研究的目的是分析感知压力量表（PSS）在752名年龄在18至62岁（M = 30.18，DE = 10.175）的人群样本中的心理测量特性，其中44%（331人）为女性，56%（421人）为男性，来自秘鲁利马。通过验证性因素分析和拉施模型得出的结果证实了12项版本（PSS - 12）的整体适配性，存在两个相互独立的正交因素，并且还证明了根据性别具有度量等价性以及足够的内部一致性。这些结果使我们能够推荐在秘鲁人群中使用PSS - 12来测量压力。
