The internal consistency, test-retest reliability and factor structure of the Castilian Spanish version of the 12-item General Health Questionnaire (GHQ) were studied with a sample of 1930 Spanish adolescents (M age=15.9 yr., SD=2.1). Cronbach alpha for the whole sample was .85 (.81 for boys, .87 for girls). Test-retest reliability was also satisfactory: r=.75 for boys, .81 for girls, .79 for the whole sample. After applying principal components factor analysis with varimax rotation, two factors were identified that jointly accounted for 46.8% of the total variance, Anxiety and Social Dysfunction. The results suggest that the GHQ-12 items is a questionnaire with some satisfactory psychometric properties.
对1930名西班牙青少年（平均年龄 = 15.9岁，标准差 = 2.1）的样本进行了研究，以考察12项一般健康问卷（GHQ）卡斯蒂利亚西班牙语版本的内部一致性、重测信度和因子结构。整个样本的克朗巴赫α系数为0.85（男孩为0.81，女孩为0.87）。重测信度也令人满意：男孩为r = 0.75，女孩为0.81，整个样本为0.79。在应用主成分因子分析和方差最大化旋转后，确定了两个因子，它们共同解释了总方差的46.8%，即焦虑和社会功能障碍。结果表明，GHQ - 12项问卷具有一些令人满意的心理测量学特性。
