The Perceived Stress Scale-10 (PSS-10) is widely used to assess stress perception. The aim of this study was to translate the original PSS-10 into Malay and assess the reliability and validity of the Malay version among nurses.
The Malay version of the PSS-10 was distributed among 229 nurses from four government hospitals in Selangor State. Test-retest reliability and concurrent validity was conducted with 25 nurses with the Malay version of the Depression Anxiety Stress Scales (DASS) 21. Cronbach's alpha, confirmatory factor analysis (CFA), intraclass correlation coefficient and Pearson's r correlation coefficient were used to determine the psychometric properties of the Malay PSS-10.
Two factor components were yielded through exploratory factor analysis with eigenvalues of 3.37 and 2.10, respectively. Both of the factors accounted for 54.6% of the variance. CFA yielded a two-factor structure with satisfactory goodness-of-fit indices [x/df = 2.43; comparative fit index (CFI) = 0.92, goodness-of-fit Index (GFI) = 0.94; standardised root mean square residual (SRMR) = 0.07 and root mean square error of approximation (RMSEA) = 0.08 (90% CI = 0.07-0.09)]. The Cronbach's alpha coefficient for the total items was 0.63 (0.82 for factor 1 and 0.72 for factor 2). The intraclass correlation coefficient (ICC) was 0.81 (95% CI: 0.62-0.91) for test-retest reliability testing after seven days. The total score and the negative component of the PSS-10 correlated significantly with the stress component of the DASS-21: (r = 0.61, < 0.001) and (r = 0.56, < 0.004), respectively.
The Malay version of the PSS-10 demonstrated a satisfactory level of validity and reliability to assess stress perception. Therefore, this questionnaire is valid in assessing stress perception among nurses in Malaysia.
感知压力量表-10（PSS-10）被广泛用于评估压力感知。本研究的目的是将原始的PSS-10翻译成马来语，并评估该马来语版本在护士群体中的信效度。
PSS-10的马来语版本分发给来自雪兰莪州四家政府医院的229名护士。对25名护士使用马来语版的抑郁焦虑压力量表（DASS）21进行重测信度和同时效度检验。使用克朗巴哈系数、验证性因子分析（CFA）、组内相关系数和皮尔逊相关系数来确定马来语PSS-10的心理测量特性。
通过探索性因子分析产生了两个因子成分，特征值分别为3.37和2.10。这两个因子解释了54.6%的方差。CFA产生了一个双因子结构，拟合优度指标令人满意[x/df = 2.43；比较拟合指数（CFI）= 0.92，拟合优度指数（GFI）= 0.94；标准化根均方残差（SRMR）= 0.07，近似根均方误差（RMSEA）= 0.08（90%CI = 0.07 - 0.09）]。所有项目的克朗巴哈系数为0.63（因子1为0.82，因子2为0.72）。重测信度检验在七天后的组内相关系数（ICC）为0.81（95%CI：0.62 - 0.91）。PSS-10的总分和负性成分与DASS-21的压力成分显著相关：分别为（r = 0.61，< 0.001）和（r = 0.56，< 0.004）。
PSS-10的马来语版本在评估压力感知方面表现出令人满意的效度和信度水平。因此，该问卷在评估马来西亚护士的压力感知方面是有效的。
