Who should the clinician primarily consider responses from when completing the PHQ-2 to PHQ-9?

The clinician should primarily consider responses from the patient when completing the PHQ-2 to PHQ-9. These assessments are specifically designed to evaluate the patient's self-reported symptoms of depression. The PHQ-2 serves as a brief screening tool that identifies potential depression, while the PHQ-9 is a more comprehensive assessment that quantifies the severity of depressive symptoms based on the patient's own experiences.

By focusing solely on the patient's responses, the clinician can gain insight into the individual's current mental health status and symptomatology, facilitating a more accurate diagnosis and personalized treatment plan. The patient's subjective experience is crucial, as it reflects their thoughts, feelings, and behaviors, which are central to understanding their mental health.

Considering responses from the medical chart or a caregiver may provide additional context or information, but these sources are not the primary focus for the PHQ assessments. The core intent of these tools is to capture the patient's voice and perspective regarding their mental health.
