The 10-item Kessler Psychological Distress Scale (K10) has been presented as a valid measure to assess psychological distress levels in population surveys but its dimensional structure was not consensual. Our main objective was to provide a Portuguese version of the K10 exploring the reliability and factor structure of this measure. This cross-sectional study included 694 adults collected from a web-based survey and in training entities. Results showed that 37.9% of the individuals reported significant distress symptoms. A good internal consistency of the K10 scale (α=.91) and strong inter-item correlation (ranges from .350 to .659) were found in our study but the original one-dimensional structure was not confirmed. A two-factor model considering anxiety and depression as two latent, independent but correlated factors shows a good fit with the data even across two data collection methods. The K10 tool was sensitive to sociodemographic variables. Participants aged 40 or over and belonging to the general working class presented higher distress levels. Our data indicates the Portuguese version of K10 as a reliable tool with a factor structure to assess psychological distress.
10项凯斯勒心理困扰量表（K10）已被视为在人口调查中评估心理困扰水平的有效工具，但其维度结构尚无定论。我们的主要目标是提供K10的葡萄牙语版本，并探究该量表的信度和因子结构。这项横断面研究纳入了通过网络调查和培训机构收集的694名成年人。结果显示，37.9%的个体报告有明显的困扰症状。我们的研究发现，K10量表具有良好的内部一致性（α = 0.91）和较强的项目间相关性（范围从0.350至0.659），但原始的一维结构未得到证实。一个将焦虑和抑郁视为两个潜在、独立但相关因子的双因子模型，即便在两种数据收集方法中，都与数据显示出良好的拟合度。K10工具对社会人口统计学变量敏感。40岁及以上且属于普通工人阶级的参与者表现出更高的困扰水平。我们的数据表明，K10的葡萄牙语版本是一种可靠的工具，具有评估心理困扰的因子结构。
