University students experience high levels of stress due to university transition, academic commitments, and financial matters. Higher stress perceptions along with limited coping resources endanger mental health for a considerable number of students and may ruin their performance. The current study evaluated the psychometric properties of the Cohen Perceived Stress Scale (10 items), PSS-10, in a sample of 379 female Emeriti students. Exploratory factor analysis resulted in two factors with eigenvalues of 3.88 and 1.19, which explained 60.6% of the variance. Confirmatory factor analysis revealed good model fits of two correlated factors (Comparative Fit Index (CFI) = 0.962, Tucker-Lewis Index (TLI) = 0.950, standardized root-mean-square residual (SRMR) = 0.0479, and root mean-square error of approximation (RMSEA) = 0.067). Internal consistency of the PSS-10 and its positive and negative subscales was acceptable (coefficient α = 0.67, 0.79, and 0.86, respectively). Multigroup analysis revealed that the PSS-10 holds invariance across different groups of age, marital status, and financial status (average monthly expenditure). Convergent and concurrent validity tests signify the importance of considering scores of subscales of the PSS-10 along with its total score.
由于大学过渡、学业任务和经济问题，大学生承受着高水平的压力。较高的压力感知以及有限的应对资源危及了相当一部分学生的心理健康，并可能影响他们的表现。本研究在379名阿联酋女学生样本中评估了科恩感知压力量表（10项）即PSS - 10的心理测量特性。探索性因素分析得出两个因素，特征值分别为3.88和1.19，解释了60.6%的方差。验证性因素分析显示两个相关因素的模型拟合良好（比较拟合指数（CFI）= 0.962，塔克 - 刘易斯指数（TLI）= 0.950，标准化均方根残差（SRMR）= 0.0479，近似均方根误差（RMSEA）= 0.067）。PSS - 10及其正负子量表的内部一致性是可接受的（系数α分别为0.67、0.79和0.86）。多组分析表明，PSS - 10在不同年龄、婚姻状况和财务状况（月平均支出）组中具有不变性。收敛效度和同时效度检验表明，考虑PSS - 10子量表得分及其总分具有重要意义。
