To translate the Perceived Stress Scale (versions PSS-4, -10 and -14) and to assess its psychometric properties in a sample of general Greek population.
941 individuals completed anonymously questionnaires comprising of PSS, the Depression Anxiety and Stress scale (DASS-21 version), and a list of stress-related symptoms. Psychometric properties of PSS were investigated by confirmatory factor analysis (construct validity), Cronbach's alpha (reliability), and by investigating relations with the DASS-21 scores and the number of symptoms, across individuals' characteristics. The two-factor structure of PSS-10 and PSS-14 was confirmed in our analysis. We found satisfactory Cronbach's alpha values (0.82 for the full scale) for PSS-14 and PSS-10 and marginal satisfactory values for PSS-4 (0.69). PSS score exhibited high correlation coefficients with DASS-21 subscales scores, meaning stress (r = 0.64), depression (r = 0.61), and anxiety (r = 0.54). Women reported significantly more stress compared to men and divorced or widows compared to married or singled only. A strong significant (p < 0.001) positive correlation between the stress score and the number of self-reported symptoms was also noted.
The Greek versions of the PSS-14 and PSS-10 exhibited satisfactory psychometric properties and their use for research and health care practice is warranted.
将压力知觉量表（PSS-4、-10 和 -14 版本）翻译为希腊语，并评估其在一般希腊人群样本中的心理测量学特性。
941 名个体匿名完成了包括 PSS、抑郁焦虑和压力量表（DASS-21 版本）以及一系列与压力相关的症状列表在内的问卷。通过验证性因素分析（结构效度）、克朗巴赫α系数（信度）以及个体特征与 DASS-21 评分和症状数量之间的关系来研究 PSS 的心理测量学特性。我们的分析证实了 PSS-10 和 PSS-14 的双因素结构。我们发现 PSS-14 和 PSS-10 的克朗巴赫α值（全量表为 0.82）令人满意，而 PSS-4 的克朗巴赫α值为 0.69，仅为边缘满意。PSS 评分与 DASS-21 分量表评分高度相关，表明压力（r = 0.64）、抑郁（r = 0.61）和焦虑（r = 0.54）。与男性相比，女性报告的压力明显更多，与已婚或单身相比，离婚或丧偶的人报告的压力更多。压力评分与自我报告症状数量之间存在显著（p < 0.001）正相关。
希腊语版 PSS-14 和 PSS-10 表现出令人满意的心理测量学特性，其在研究和医疗保健实践中的应用是合理的。
