Stress influences examination performance among Sri Lankan students. Validated tests are required to evaluate stress levels among elementary students in Sri Lanka. Therefore, the Perceived Stress Questionnaire 8-11 (PSQ8-11) was translated into a Sinhala version. The aim of this study was to examine the psychometric properties of the translated and adapted scale among elementary level school children in Sri Lanka and examine invariance across male and female children.
The participants were 1021 students from seven schools. After removing missing values, responses from 693 students (mean age = 9.65 ± 0.478 years, 51.8% male) were analysed for participant characteristics. Cronbach's alpha, Spearman's correlation, and confirmatory factor analysis with measurement invariance models were conducted after adding one item to the original PSQ8-11 version.
The Cronbach's alpha value for the 20-item modified PSQ8-11 Sinhala version was.788. The two subscales, psychological stress (Cronbach's alpha = 0.615) and physiological stress (Cronbach's alpha = 0.711), indicated a satisfactory level of internal consistency. Furthermore, a statistically significant correlation ( < 0.01; 2-tailed) was reported among each of the subscales. Confirmatory factor analyses demonstrated a satisfactory goodness-of-fit across the two models by confirming the theoretical constructs of the PSQ8-11 translated version with its two subscales. The two-factor model has better model fit indices compared to the unidimensional model (χ/df = 1.447, CFI = 0.947, TLI = 0.938, WRMR = 0.028, RMSEA = 0.026, SRMSR = 0.0341, and PCLOSE = 1 of the two-factor model). Measurement variance across gender was supported by the establishment of configural and metric invariances.
Acceptable psychometric properties for the PSQ8-11 Sinhala version were observed in elementary schoolers in Sri Lanka.
压力会影响斯里兰卡学生的考试成绩。需要经过验证的测试来评估斯里兰卡小学生的压力水平。因此，将感知压力问卷8 - 11（PSQ8 - 11）翻译成了僧伽罗语版本。本研究的目的是检验该翻译和改编后的量表在斯里兰卡小学生中的心理测量特性，并检验男女生之间的不变性。
参与者为来自七所学校的1021名学生。在去除缺失值后，对693名学生（平均年龄 = 9.65 ± 0.478岁，51.8%为男性）的回答进行了参与者特征分析。在原始PSQ8 - 11版本中增加一个项目后，进行了克朗巴哈系数、斯皮尔曼相关性分析以及带有测量不变性模型的验证性因素分析。
20项修改后的PSQ8 - 11僧伽罗语版本的克朗巴哈系数值为0.788。两个子量表，心理压力（克朗巴哈系数 = 0.615）和生理压力（克朗巴哈系数 = 0.711），显示出令人满意的内部一致性水平。此外，各子量表之间均报告了具有统计学意义的相关性（< 0.01；双侧）。验证性因素分析通过确认PSQ8 - 11翻译版本及其两个子量表的理论结构，表明两个模型的拟合优度令人满意。与单维模型相比，两因素模型具有更好的模型拟合指数（两因素模型的χ/df = 1.447，CFI = 0.947，TLI = 0.938，WRMR = 0.028，RMSEA = 0.026，SRMSR = 0.0341，PCLOSE = 1）。构型和度量不变性的建立支持了性别间的测量方差。
在斯里兰卡的小学生中观察到PSQ8 - 11僧伽罗语版本具有可接受的心理测量特性。
