The aim of the current study was to assess the reliability, validity and the psychometric properties of the Greek translation of the Symptoms Rating Scale For Depression and Anxiety. The scale consists of 42 items and permits the calculation of the scores of the Beck Depression Inventory (BDI)-21, the BDI 13, the Melancholia Subscale, the Asthenia Subscale, the Anxiety Subscale and the Mania Subscale
29 depressed patients 30.48 +/- 9.83 years old, and 120 normal controls 27.45 +/- 10.85 years old entered the study. In 20 of them (8 patients and 12 controls) the instrument was re-applied 1-2 days later. Translation and Back Translation was made. Clinical Diagnosis was reached by consensus of two examiners with the use of the SCAN v.2.0 and the IPDE. CES-D and ZDRS were used for cross-validation purposes. The Statistical Analysis included ANOVA, the Spearman Correlation Coefficient, Principal Components Analysis and the calculation of Cronbach's alpha.
The optimal cut-off points were: BDI-21: 14/15, BDI-13: 7/8, Melancholia: 8/9, Asthenia: 9/10, Anxiety: 10/11. Chronbach's alpha ranged between 0.86 and 0.92 for individual scales. Only the Mania subscale had very low alpha (0.12). The test-retest reliability was excellent for all scales with Spearman's Rho between 0.79 and 0.91.
The Greek translation of the SRSDA and the scales that consist it are both reliable and valid and are suitable for clinical and research use with satisfactory properties. Their properties are close to those reported in the international literature. However one should always have in mind the limitations inherent in the use of self-report scales.
本研究旨在评估希腊语版抑郁与焦虑症状评定量表的信度、效度及心理测量学特性。该量表包含42个项目，可计算贝克抑郁量表（BDI）-21、BDI-13、抑郁亚型、乏力亚型、焦虑亚型及躁狂亚型的得分。
29名年龄为30.48±9.83岁的抑郁症患者及120名年龄为27.45±10.85岁的正常对照者参与本研究。其中20人（8名患者和12名对照者）在1-2天后再次使用该工具。进行了翻译及回译。由两名检查者使用SCAN v.2.0和IPDE达成临床诊断共识。使用CES-D和ZDRS进行交叉验证。统计分析包括方差分析、斯皮尔曼相关系数、主成分分析及克朗巴哈系数计算。
最佳截断点为：BDI-21：14/15，BDI-13：7/8，抑郁亚型：8/9，乏力亚型：9/10，焦虑亚型：10/11。各分量表的克朗巴哈系数在0.86至0.92之间。只有躁狂亚型的系数非常低（0.12）。所有量表的重测信度都很好，斯皮尔曼相关系数在0.79至0.91之间。
SRSDA的希腊语翻译版本及其所包含的量表既可靠又有效，适用于临床和研究，具有令人满意的特性。它们的特性与国际文献报道的相近。然而，人们应始终牢记使用自我报告量表所固有的局限性。
