Abstract

Background: The most common mental disorders in both outpatient settings and the general population are depression and anxiety, which frequently coexist. Both of these disorders are associated with considerable disability.

Objective: When the disorders co-occur, the disability is even greater. Authors sought to test an ultra-brief screening tool for both.

Method: Validated two-item ultra-brief screeners for depression and anxiety were combined to constitute the Patient Health Questionnaire for Depression and Anxiety (the PHQ-4). Data were analyzed from 2,149 patients drawn from 15 primary-care clinics in the United States.

Results: Factor analysis confirmed two discrete factors (Depression and Anxiety) that explained 84% of the total variance. Increasing PHQ-4 scores were strongly associated with functional impairment, disability days, and healthcare use. Anxiety had a substantial effect on functional status that was independent of depression.

Conclusion: The PHQ-4 is a valid ultra-brief tool for detecting both anxiety and depressive disorders.

一种超简短的焦虑和抑郁筛查量表:PHQ-4。

背景:在门诊和一般人群中最常见的精神障碍是抑郁和焦虑，它们经常共存。这两种疾病都与相当大的残疾有关。目的:当疾病同时发生时，残疾更大。作者试图为这两种疾病测试一种超简短的筛查工具。方法:采用经验证的抑郁和焦虑两项超简短筛选问卷，组成《患者抑郁和焦虑健康问卷》(PHQ-4)。研究人员分析了来自美国15家初级保健诊所的2149名患者的数据。结果:因子分析证实了两个离散因素(抑郁和焦虑)解释了84%的总方差。PHQ-4评分的增加与功能损害、残疾天数和医疗保健使用密切相关。焦虑对独立于抑郁的功能状态有实质性影响。结论:PHQ-4是一种有效的超简短的检测焦虑和抑郁障碍的工具。
