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.
背景
在门诊和普通人群中，最常见的精神障碍是抑郁症和焦虑症，它们经常同时存在。这两种疾病都会导致严重的残疾。
目的
当这些疾病同时发生时，残疾程度会更大。作者试图测试一种针对这两种疾病的超简短筛查工具。
方法
将经过验证的用于筛查抑郁和焦虑的两个项目的超简短筛查工具组合在一起，构成了患者健康问卷抑郁和焦虑量表（PHQ-4）。对来自美国 15 个初级保健诊所的 2149 名患者的数据进行了分析。
结果
因子分析证实了两个离散的因素（抑郁和焦虑），它们解释了总方差的 84%。PHQ-4 评分的增加与功能障碍、残疾天数和医疗保健使用密切相关。焦虑对功能状态的影响很大，且独立于抑郁。
结论
PHQ-4 是一种有效的超简短工具，可用于检测焦虑和抑郁障碍。
