Abstract

Objective

To determine the reliability, construct and criterion validity of the Glasgow Depression Scale (GDS) in Colombian people with intellectual disability (ID).

Methods

One hundred and twenty participants who underwent the GDS and a clinical interview for the diagnosis of depressive disorders were included. To determine the validity of the convergent construct, the Hospital Anxiety and Depression Scale (HADS) for people with ID was applied to a subgroup, and for the evaluation of test–retest reproducibility, a new application of the GDS was made 7–10 days later.

Results

In the confirmatory factorial analysis, it was found that the unidimensional structure had an adequate fit, but it was better for the two-dimensional bifactorial structure: “ideas and depressive mood” and “changes in energy”. It had good internal consistency (Cronbach's alpha: 0,85 (95% CI: 0.81–0.89). In test–retest reproducibility, the intraclass correlation coefficient was 0.56 (95% CI: 0.34–0.72) for the total scale. Convergent validity was demonstrated by the correlation of 0.6 of the GDS with the HADS, and there is discriminative validity by the difference in median scores between patients with and without a depressive episode (23 vs. 18, P = 0.0001). The area under the receiver operating characteristic curve for diagnosis of depression was 0.80 (95% CI: 0.70–0.90) and the sensitivity was 95% (95% CI: 75.1–99.9) for a cutoff point of 18.

Conclusion

The GDS is reliable and validated for depression screening in Colombian people with ID.
哥伦比亚智障人群格拉斯哥抑郁量表的验证
目的探讨哥伦比亚智力残疾者格拉斯哥抑郁量表(GDS)的信度、结构和效度。方法选取120名接受GDS和临床访谈的抑郁症患者作为研究对象。为了确定趋同结构的有效性,我们将ID患者的医院焦虑与抑郁量表(HADS)应用于一个亚组,并在7-10天后重新应用GDS评估重测的可重复性。结果验证性析因分析发现,一维结构具有较好的拟合性,但二维双因结构“观念与抑郁情绪”和“能量变化”的拟合性较好。它具有良好的内部一致性(Cronbach's alpha: 0.85 (95% CI: 0.81-0.89)。在重测重现性方面,总量表的类内相关系数为0.56 (95% CI: 0.34-0.72)。GDS与HADS的相关性为0.6,证明了趋同效度,有抑郁发作和没有抑郁发作的患者中位评分的差异证明了判别效度(23比18,P = 0.0001)。诊断抑郁症的受试者工作特征曲线下面积为0.80 (95% CI: 0.70-0.90),截断点为18时,灵敏度为95% (95% CI: 75.1-99.9)。结论GDS可用于哥伦比亚ID患者的抑郁筛查。
