对于少数民族来说，抑郁症是一个重要的问题，但由于缺乏强有力的测量方法和已建立的心理测量特性，这一问题仍未得到充分的研究。一种筛查工具，病人健康问卷-9 (PHQ-9)，是为初级保健而开发的，也在研究环境中得到了普及。PHQ-9的信度和效度在主要的白种人样本中得到了很好的确立，此外还有许多少数民族。然而，几乎没有证据表明它在西班牙裔美国人中的效用，这是美国一个庞大且不断增长的文化群体。在本研究中，我们调查了PHQ-9在西班牙裔美国女性中的信度和结构效度。来自南加州的479名拉丁裔女性的社区样本用她们喜欢的英语或西班牙语完成了PHQ-9。克朗巴赫的alpha值表明，英语和西班牙语版本都有很好的内部一致性。采用多组验证性因子分析研究结构效度。结果支持类似的单因素结构，在英语和西班牙语拉丁裔中具有相同的反应模式和差异。这些结果表明PHQ-9可以在英语和西班牙语版本中自信地用于筛选拉丁美洲人的抑郁症。
Depression is a significant problem for ethnic minorities that remains understudied partly due to a lack of strong measures with established psychometric properties. One screening tool, the Patient Health Questionnaire-9 (PHQ-9), which was developed for use in primary care has also gained popularity in research settings. The reliability and validity of the PHQ-9 has been well established among predominantly Caucasian samples, in addition to many minority groups. However, there is little evidence regarding its utility among Hispanic Americans, a large and growing cultural group in the United States. In this study, we investigated the reliability and structural validity of the PHQ-9 in Hispanic American women. A community sample of 479 Latina women from southern California completed the PHQ-9 in their preferred language of English or Spanish. Cronbach's alphas suggested that there was good internal consistency for both the English- and Spanish-language versions. Structural validity was investigated using multigroup confirmatory factor analysis. Results support a similar one-factor structure with equivalent response patterns and variances among English- and Spanish-speaking Latinas. These results suggest that the PHQ-9 can be used with confidence in both English and Spanish versions to screen Latinas for depression.
