BACKGROUND
The Perceived Stress Scale 10 (PSS-10) is a validated and reliable instrument to measure global levels of perceived stress. This study aims to assess the internal consistency, reliability, and factor structure of the Malay version of the PSS-10 for use among medical students.
METHODS
The original English version of the PSS-10 was translated and back-translated into Malay language. The Malay version was distributed to 242 Bachelor of Medical Science students in a private university in Malaysia. Test-retest reliability was assessed in 70 students. An exploratory principal component factor analysis with varimax rotation was performed. Reliability was tested using the intraclass correlation coefficient (ICC).
RESULTS
All 242 students participated in the initial questionnaire study (validity and factor structure), and 70 students participated in the test-retest reliability of the study. Exploratory factor analysis yielded 2 factors that accounted for 57.8% of the variance. Cronbach's alpha coefficients for the 2 factors were 0.85 and 0.70, respectively. The reliability test showed an ICC of 0.82 (95% CI: 0.70, 0.89).
CONCLUSION
The Malay version of the PSS-10 showed adequate psychometric properties. It is a useful instrument for measuring stress among medical students in Malaysia.
背景
感知压力量表10（PSS - 10）是一种经过验证且可靠的工具，用于测量感知压力的总体水平。本研究旨在评估供医学生使用的马来语版PSS - 10的内部一致性、可靠性和因子结构。
方法
PSS - 10的原始英文版被翻译成马来语并进行回译。马来语版被分发给马来西亚一所私立大学的242名医学科学学士学生。对70名学生进行了重测信度评估。进行了采用方差最大化旋转的探索性主成分因子分析。使用组内相关系数（ICC）测试可靠性。
结果
所有242名学生参与了初始问卷调查研究（效度和因子结构），70名学生参与了该研究的重测信度评估。探索性因子分析得出2个因子，解释了57.8%的方差。这2个因子的克朗巴哈α系数分别为0.85和0.70。可靠性测试显示ICC为0.82（95%置信区间：0.70，0.89）。
结论
马来语版PSS - 10显示出足够的心理测量学特性。它是测量马来西亚医学生压力的一种有用工具。
