Understanding the PHQ-9: An Introduction to the Assessment Tool

The Patient Health Questionnaire-9 (PHQ-9) is a widely-used assessment tool that helps in evaluating and measuring the severity of depression. It consists of nine questions that are based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for major depressive disorder.

The PHQ-9 is a self-report questionnaire designed to be completed by individuals who may be experiencing symptoms of depression. It assesses the frequency and severity of symptoms such as depressed mood, loss of interest or pleasure, changes in appetite or weight, sleep disturbances, fatigue or loss of energy, feelings of worthlessness or guilt, difficulty concentrating, psychomotor agitation or retardation, and suicidal ideation.

Each question in the PHQ-9 is scored on a scale of 0-3, with higher scores indicating more severe symptoms. The total score can range from 0 to 27, with higher scores indicating a higher likelihood of depression. The PHQ-9 is commonly used in clinical practice, research studies, and screening programs to identify and assess individuals who may require further evaluation or treatment for depression.
