The objective of the present study was to analyze the psychometric properties of validity and reliability of the Goldberg Anxiety and Depression Scale (GADS) in Ecuadorian university students, since a cultural validation of the instrument has not been found in Ecuador. The study population consisted of a non-probabilistic sample of 600 participants (59.6% women and 40.4% men, M = 21 years, SD = 2.82). The factorial structure was examined with the method of extraction by Parallel Analysis of unweighted least squares (ULS) and of prominent rotation. In both, internal consistency was evaluated by Cronbach's alpha coefficients and composite reliability. Like the original version, both subscales have a factorial structure of one dimension and are considered good in terms of reliability, which concludes that the scale meets the criteria of validity and reliability in Ecuador.
本研究的目的是分析戈德堡焦虑抑郁量表（GADS）在厄瓜多尔大学生中的效度和信度的心理测量特性，因为在厄瓜多尔尚未发现对该工具进行文化验证的研究。研究人群包括一个由600名参与者组成的非概率样本（59.6%为女性，40.4%为男性，平均年龄M = 21岁，标准差SD = 2.82）。采用非加权最小二乘法（ULS）并行分析提取法和正交旋转法对因子结构进行了检验。在这两种方法中，通过克朗巴赫α系数和组合信度来评估内部一致性。与原始版本一样，两个子量表都具有一维的因子结构，并且在信度方面被认为是良好的，这表明该量表在厄瓜多尔符合效度和信度标准。
