What does the PHQ-9 questionnaire primarily screen for?

1. Anxiety

2. Depression

3. Bipolar disorder

4. Stress levels

The correct answer is: Depression

The PHQ-9 questionnaire is specifically designed to screen for depression. It consists of nine questions that assess the frequency of symptoms associated with major depressive disorder, such as loss of interest, feelings of hopelessness, and changes in sleep or appetite. The scoring system of the PHQ-9 helps healthcare providers determine the severity of depression in individuals, making it a valuable tool for both screening and monitoring treatment response. The focus of the PHQ-9 on depressive symptoms distinguishes it from assessments for anxiety or stress, which would involve different sets of questions tailored to those specific conditions. While the instrument may indirectly provide insight into how depression affects stress levels or may coexist with anxiety disorders, its primary intent is to identify and evaluate the presence and severity of depressive symptoms. This targeted approach allows clinicians to effectively identify individuals who may benefit from further evaluation or treatment for depression.
