Abstract

Introduction

The detection of anxiety symptoms among health workers who care for patients infected with COVID-19 is a current priority. Fast and valid instruments are required for this population group. The objective is to establish the construct validity and reliability of the Generalised Anxiety Disorder (GAD-7) scale in Colombian doctors during the COVID-19 lockdown.

Methods

E-health study, in which cross-sectional data were collected online (n = 1030) from 610 COVID doctors and 420 non-COVID doctors, during the Colombian lockdown, between 20 April and 10 August 2020. Each subject was contacted, and they confirmed their participation, identity and professional role.

Results

A single factor factorial structure was found, made up of the 7 items of the instrument, which managed to explain 70% of the variance. The goodness of fit indices (RMSEA = 0.080; CFI = 0.995; SRMR = 0.053; p < 0.001) showed an “acceptable” unidimensionality and adequate factor loadings in each item of the GAD-7, >0.070. Finally, the internal consistency of the instrument was good, with a Cronbach’s alpha of 0.920 (95%IC, 8.80–9.71).

Conclusions

The GAD-7 is an instrument that presents adequate indicators of validity and reliability. It is an excellent tool that is reliable and easy and fast to use for the detection of generalised anxiety symptoms in medical personnel caring (or not) for patients infected with COVID-19.

新冠肺炎大流行期间哥伦比亚医疗专业人员的GAD-7一般性焦虑症量表：构建有效性和可靠性。

简介：在护理新冠肺炎感染者的卫生工作者中检测焦虑症状是当前的优先事项。这一群体需要快速有效的仪器。目的是在新冠肺炎封锁期间，在哥伦比亚医生中建立广泛性焦虑症（GAD-7）量表的结构有效性和可靠性。方法：电子健康研究，横断面数据在线收集（n = 1030），来自610名新冠肺炎医生和420名非新冠肺炎患者。联系了每一位受试者，他们确认了自己的参与、身份和职业角色。结果：发现了一个由仪器的7个项目组成的单因素析因结构，该结构能够解释70%的方差。拟合优度指数（RMSEA = 0.080；CFI = 0.995；SRMR = 0.053；p 0.070。最后，该仪器的内部一致性良好，Cronbachα为0.920（95%IC，8.80-9.71）。结论：GAD-7是一种提供足够的有效性和可靠性指标的仪器。这是一种可靠、简单、快速的优秀工具，可用于检测医护人员（或非医护人员）感染新冠肺炎患者的全身性焦虑症状。
