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.
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.
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).
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.
在照顾 COVID-19 感染者的医护人员中，发现焦虑症状是当务之急。针对这一人群，需要快速有效的工具。本研究旨在确定哥伦比亚 COVID-19 封锁期间医生群体中广泛性焦虑障碍（GAD-7）量表的结构效度和信度。
采用电子健康研究方法，于 2020 年 4 月 20 日至 8 月 10 日，在哥伦比亚封锁期间，通过网络（n=1030），从 610 名 COVID 医生和 420 名非 COVID 医生中收集了横断面数据。联系每位受试者，确认其参与、身份和职业角色。
发现一个由 7 个项目组成的单一因素因子结构，该结构解释了 70%的方差。拟合优度指数（RMSEA=0.080；CFI=0.995；SRMR=0.053；p<0.001）显示，GAD-7 具有“可接受”的单维性和各个项目的适当因子负荷，均>0.070。最后，该工具的内部一致性良好，Cronbach's alpha 为 0.920（95%CI，8.80-9.71）。
GAD-7 是一种具有良好信度和效度的工具。它是一种可靠的工具，易于使用，可快速检测照顾（或不照顾）COVID-19 感染者的医护人员的一般性焦虑症状。
