The 10-item Perceived Stress Scale (PSS-10) is commonly used to measure stress levels in postoperative patients, as research shows that high levels of stress can affect postoperative outcomes. By using the PSS-10, healthcare providers can understand patients' psychological well-being before and after surgery, helping improve recovery and overall health. This study focuses on assessing the reliability and validity of the 10-item Persian version of the PSS (PSS-10-P) in postoperative patients.
In a methodological study conducted between October to December 2023, a sample of 400 patients who had undergone surgery in 17 Shahrivar Hospital, Amol, Iran were selected using a convenience sampling method. The PSS-10 scale utilized in the study was translated, and its psychometric properties were evaluated through assessments of construct validity, including exploratory (n = 200) and confirmatory (n = 200) factor analysis, convergent validity, and discriminant validity. Furthermore, the study examined the internal consistency of the scale to ensure its reliability.
The mean age of the participants was 44.38 (SD= 13.49) years. The results of exploratory factor analysis with Promax rotation extracted two factors accounting for 83.82% of the variance comprising 10 items. After necessary modifications during CFA, the final model was approved. As for reliability, the Cronbach's alpha, CR, and MaxR for all constructs were greater than 0.7, demonstrating good internal consistency and construct reliability.
According to these results, the Persian version of PSS-10 has a valid structure and acceptable reliability. This scale can be used by health professionals in many ways.
10项感知压力量表（PSS - 10）常用于测量术后患者的压力水平，因为研究表明高水平的压力会影响术后结果。通过使用PSS - 10，医疗保健提供者可以了解患者手术前后的心理健康状况，有助于改善恢复情况和整体健康。本研究重点评估10项波斯语版PSS（PSS - 10 - P）在术后患者中的信度和效度。
在2023年10月至12月进行的一项方法学研究中，采用便利抽样法从伊朗阿莫勒市17 Shahrivar医院的400例手术患者中选取样本。对研究中使用的PSS - 10量表进行了翻译，并通过结构效度评估（包括探索性因素分析（n = 200）和验证性因素分析（n = 200））、收敛效度和区分效度来评估其心理测量特性。此外，该研究还检验了量表的内部一致性以确保其可靠性。
参与者的平均年龄为44.38岁（标准差 = 13.49）。采用Promax旋转的探索性因素分析结果提取了两个因素，占方差的83.82%，包含10个项目。在CFA期间进行必要修改后，最终模型获得批准。至于信度，所有结构的Cronbach's alpha、CR和MaxR均大于0.7，表明具有良好的内部一致性和结构可靠性。
根据这些结果，波斯语版PSS - 10具有有效的结构和可接受的信度。该量表可供卫生专业人员在多种情况下使用。
