Increased levels of stress in nursing students are negatively related to caring behaviours and also result in poorer job proficiency and nurses who are more inclined to leave the profession. The Perceived Stress Scale (PSS), developed by Sheu and colleagues, is one of the most cited instruments for measuring stress and sources of stress amongst nursing students in international studies. However, it has not been widely validated for this purpose.
This research aimed to test the construct validity and reliability of the PSS for South African nursing students.
A cross-sectional survey was conducted at a Central South African University, and 471 of the 685 registered nursing students (68.8% response rate) participated in the study. Questionnaires were distributed and collected during classes. Confirmatory factor analysis was performed to test the hypothesised six-factor latent structure and determine the construct validity of the PSS. The internal consistency of the PSS was measured using Cronbach's alpha.
The model fit was a good fit and supported the six-factor latent structure as stress from (1) taking care of patients, (2) teachers and nursing staff, (3) assignments and workload, (4) peers and daily life, (5) lack of professional knowledge and skills and (6) clinical environment. Overall the PSS had a Cronbach's alpha of 0.93.
The results confirm the construct validity and the internal consistency of the PSS for South African nursing students.
护理专业学生的压力水平升高与关怀行为呈负相关，还会导致工作熟练度降低，以及更倾向于离开护理行业的护士。谢和同事开发的《感知压力量表》（PSS）是国际研究中用于衡量护理专业学生压力和压力源的最常被引用的工具之一。然而，该量表尚未被广泛验证用于该目的。
本研究旨在检验 PSS 在南非护理专业学生中的结构效度和信度。
在南非中部的一所大学进行了横断面调查，共有 685 名注册护理学生中的 471 名（68.8%的应答率）参与了这项研究。在课堂上分发和收集问卷。采用验证性因子分析来检验假设的六因素潜在结构，并确定 PSS 的结构效度。使用 Cronbach's alpha 来衡量 PSS 的内部一致性。
模型拟合度良好，支持 PSS 的六因素潜在结构，即（1）照顾患者，（2）教师和护理人员，（3）任务和工作量，（4）同伴和日常生活，（5）缺乏专业知识和技能，以及（6）临床环境。总体而言，PSS 的 Cronbach's alpha 为 0.93。
结果证实了 PSS 在南非护理专业学生中的结构效度和内部一致性。
