BACKGROUND
Simple and brief questionnaires with adequate psychometric properties are useful for the early detection of depressive disorders.
AIM
To analyze the psychometric behavior of the Patient Health Questionnaire (PHQ-9) in Chile.
MATERIAL AND METHODS
Data were collected from 1,738 adult patients, consulting in primary health care centers. The values obtained in the PHQ-9 were compared with those of the Composite International Diagnostic Interview (CIDI).
RESULTS
The mean score of PHQ-9 was 4.85 ± 5.57. Internal consistency indices were high. McDonald's ω coefficient of was 0.90 and Cronbach alpha 0.89. A confirmatory factor analysis showed a good fit of the one-dimensional model. Using a cutoff score of seven determined with the receiver operating characteristic (ROC) curve, the sensitivity and specificity of the instrument were 0.8 and 0.7, when compared with CIDI diagnoses.
CONCLUSIONS
PHQ-9 is a useful instrument for the screening of depressive disorders in primary health care centers in Chile.
背景

目的
分析患者健康问卷（PHQ - 9）在智利的心理测量行为。
材料与方法
收集了1738名在初级卫生保健中心就诊的成年患者的数据。将PHQ - 9获得的值与综合国际诊断访谈（CIDI）的值进行比较。
结果
PHQ - 9的平均得分为4.85±5.57。内部一致性指标较高。麦克唐纳ω系数为0.90，克朗巴赫α系数为0.89。验证性因素分析表明一维模型拟合良好。与CIDI诊断相比，使用通过受试者工作特征（ROC）曲线确定的截断分数7时，该工具的敏感性和特异性分别为0.8和0.7。
结论
PHQ - 9是智利初级卫生保健中心筛查抑郁症的有用工具。
