The present study evaluated the psychometric properties of the Patient Health Questionnaire-4 (PHQ-4), a screener of psychological distress, in English- and Spanish-speaking Hispanic Americans. Hispanic American adults ( = 436) completed the PHQ-4, which yields two subscales (anxiety and depression) that can be summed to create a total score. Multiple-group confirmatory factor analysis was used to evaluate structural validity. The two-factor structure was the best fit to the data for both English- and Spanish-speaking Hispanic Americans and items loaded equivalently across groups, demonstrating measurement invariance. Internal consistency reliability was good as measured by coefficient alpha. Construct validity was evidenced by significant expected relationships with perceived stress. These findings provide support for the reliability and validity of the PHQ-4 as a brief measure of psychological distress for English- or Spanish-speaking Hispanic Americans.
本研究评估了患者健康问卷-4(PHQ-4)在说英语和西班牙语的西班牙裔美国人中的心理测量特性,该问卷是一种心理困扰筛查工具。西班牙裔美国成年人(n = 436)完成了PHQ-4,该问卷产生两个分量表(焦虑和抑郁),可以将其相加以得出总分。使用多组验证性因素分析来评估结构效度。两因素结构最适合说英语和西班牙语的西班牙裔美国人的数据,并且各项目在不同组中的负荷相当,表明测量不变性。以α系数衡量,内部一致性信度良好。与感知压力的显著预期关系证明了结构效度。这些发现为PHQ-4作为说英语或西班牙语的西班牙裔美国人心理困扰的简短测量工具的信度和效度提供了支持。
