affects millions of people worldwide, making early identification essential for timely support. One of the most widely used screening questionnaires is the <strong>PHQ-9 score<\/strong>, which helps estimate the <strong>depression level<\/strong> by evaluating symptom frequency over the past two weeks.<\/p>\n<p>Healthcare professionals in primary care, hospitals, and mental health clinics frequently use the PHQ-9 because it is simple, evidence-based, and easy to administer. However, understanding what each score means is equally important for patients, caregivers, and anyone interested in mental health awareness.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_the_PHQ-9\"><\/span>What Is the PHQ-9?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Patient Health Questionnaire-9 (PHQ-9) is a validated depression screening questionnaire containing nine questions. Each question corresponds to one of the diagnostic symptoms of major depressive disorder.<\/p>\n<p>The questionnaire asks how often each symptom has occurred during the previous two weeks.<\/p>\n<p>Possible responses include:<\/p>\n<ul>\n<li>\n<p>Not at all (0)<\/p>\n<\/li>\n<li>\n<p>Several days (1)<\/p>\n<\/li>\n<li>\n<p>More than half the days (2)<\/p>\n<\/li>\n<li>\n<p>Nearly every day (3)<\/p>\n<\/li>\n<\/ul>\n<p>The responses are added together to create the final <strong>PHQ-9 score<\/strong>, ranging from 0 to 27.<\/p>\n<h2><span class=\"ez-toc-section\"

communication between patients and providers<\/p>\n<\/li>\n<\/ul>\n<p>Because the same questionnaire can be repeated over time, healthcare professionals can observe whether symptoms are improving,
