Previous research has shown that individuals suffering from depression and generalized anxiety disorder (GAD) seem to have inhibitory control deficits compared with healthy controls. However, few studies have been conducted in Spanish-speaking countries. Thus, this study aims to analyze the performance on the Stroop Color and Word Test (SCWT) between groups of Colombian participants with clinical levels of depression and GAD symptoms and a nonclinical control group. According to previous research, we expected to find significant differences in inhibitory control among groups. An ex post facto design was implemented. The SCWT was administered to a total sample of 105 individuals (64.8% women, M = 22.94 years, SD = 4.62), including 27 depressed and 15 anxious participants according to their scores on the Personal Health Questionnaire–9 and the Generalized Anxiety Disorder–7, respectively. Bayesian t-tests showed that depressed participants showed the same processing speed but lower scores on inhibitory control than healthy controls, BF = 13.70, δ = 0.50, 95% CI [0.08, 0.94]. Conversely, anxious participants showed deficits in processing speed, SCWT-Word: BF = 16.19, δ = 0.68, 95% CI [0.15, 1.24]; SCWT-Color: BF = 5.98, δ = 0.50, 95% CI [–0.01, 1.04], but not in inhibitory control compared with the nonanxious counterparts. This study provides preliminary evidence concerning the inhibitory control deficits in Colombian depressed individuals and processing speed deficits in those experiencing clinical levels of GAD symptoms.

具有临床抑郁和焦虑症状水平的个体的抑制控制

先前的研究表明，与健康对照组相比，患有抑郁症和广泛性焦虑症 (GAD) 的个体似乎存在抑制性控制缺陷。然而，很少有研究在讲西班牙语的国家进行。因此，本研究旨在分析具有临床抑郁症和 GAD 症状水平的哥伦比亚参与者组与非临床对照组之间的 Stroop 颜色和单词测试 (SCWT) 的表现。根据之前的研究，我们预计会发现组间抑制控制存在显着差异。实施了事后设计。SCWT 对 105 名个体（64.8% 的女性，米= 22.94 岁，标清= 4.62），包括 27 名抑郁和 15 名焦虑的参与者，根据他们在个人健康问卷 9 和广泛性焦虑症 7 上的得分分别。贝叶斯吨- 测试表明，抑郁的参与者表现出相同的处理速度，但抑制控制的分数低于健康对照组，高炉= 13.70, δ = 0.50, 95% CI [0.08, 0.94]。相反，焦虑的参与者表现出处理速度的缺陷，SCWT-Word：高炉= 16.19, δ = 0.68, 95% CI [0.15, 1.24]；SCWT-颜色：高炉= 5.98, δ = 0.50, 95% CI [–0.01, 1.04]，但与不焦虑的对应物相比，不在抑制控制中。这项研究提供了关于哥伦比亚抑郁症患者的抑制控制缺陷和经历 GAD 症状临床水平的人的处理速度缺陷的初步证据。
