Definition & Meaning
The Patient Health Questionnaire (PHQ-2/9) is a tool used for screening, diagnosing, monitoring, and measuring the severity of depression in adolescents and adults. The PHQ-2 is a preliminary evaluation, consisting of the first two questions from the PHQ-9, to quickly assess whether further investigation is warranted. The PHQ-9 expands on this by providing a more in-depth examination of depression symptoms to determine their severity.
Key Characteristics
- PHQ-2 Focus: Concentrates on the frequency of depressed mood and anhedonia over the past two weeks.
- PHQ-9 Coverage: Expands to include additional symptoms such as sleep disturbances, fatigue, changes in appetite, feelings of worthlessness, and concentration difficulties.
How to Use the Patient Health Questionnaire PHQ2 9
Using the PHQ-2/9 involves assessing participants with a standardized set of questions to identify depression levels. The user should follow these steps:
- Administer the PHQ-2: Begin by asking the participant the first two questions to evaluate the presence of depressive symptoms.
- Interpret PHQ-2 Results: A score of three or more suggests the need for the complete PHQ-9 assessment.
- Administer the PHQ-9: Use this when PHQ-2 results indicate potential depression. It consists of a broader question set that covers various depressive symptoms.
Practical Example
A primary care physician might use the PHQ-2/9 during a regular check-up to screen adolescents and adults for depression, integrating it into the patient's electronic health records for continuous monitoring.
