The General Health Questionnaire - 12 (GHQ-12) is a widely used screening self-report for emotional disorders among adults. However, there is little evidence concerning the validity of the GHQ-12 in Colombia and its factorial invariance between nonclinical and clinical samples. Accordingly, the current study aims to explore the GHQ-12 validity in Colombian nonclinical and clinical samples. The GHQ-12 was administered to a total of 1641 participants, including a sample of undergraduates, one of general population, and a clinical sample. The internal consistency of the GHQ-12 across samples was good (overall alpha of .90). The one-factor model showed a good fit to the data and was considered theoretically more coherent than the two-factor model with positive and negative items loading in separate factors. Metric and scalar invariance were observed across nonclinical and clinical samples. The GHQ-12 scores were strongly and positively related to emotional symptoms and experiential avoidance, and negatively related to life satisfaction. According to the receiver operating characteristic (ROC) curves, a threshold score of 11/12 was optimal to identify emotional disorders. In conclusion, the GHQ-12 is a valid screening self-report in Colombia that provides scores that can be compared across clinical and nonclinical participants.
一般健康问卷-12 项（GHQ-12）是一种广泛用于成年人情绪障碍筛查的自评量表。然而，关于 GHQ-12 在哥伦比亚的有效性及其在非临床和临床样本之间的因子不变性的证据很少。因此，本研究旨在探讨 GHQ-12 在哥伦比亚非临床和临床样本中的有效性。共对 1641 名参与者进行了 GHQ-12 测试，包括大学生样本、一般人群样本和临床样本。GHQ-12 在各样本中的内部一致性较好（总体 alpha 值为.90）。单因素模型对数据的拟合较好，与将正性和负性项目分别加载在不同因子中的两因素模型相比，在理论上更具连贯性。在非临床和临床样本中均观察到度量不变性和标度不变性。GHQ-12 得分与情绪症状和体验回避呈强正相关，与生活满意度呈负相关。根据受试者工作特征（ROC）曲线，11/12 分的阈值是识别情绪障碍的最佳得分。总之，GHQ-12 是一种在哥伦比亚有效的筛查自评量表，提供了可以在临床和非临床参与者之间进行比较的分数。
