What is Patient Health Questionnaire-15 (PHQ-15)
The Patient Health Questionnaire-15 (PHQ-15) is a trusted tool for checking physical symptoms. It helps doctors measure somatic symptom severity effectively. This brief survey focuses on fifteen common physical complaints that account for more than ninety percent of visits to primary care clinics. Patients rate issues like stomach pain, back pain, and fatigue on a simple scale with three options ranging from "not bothered at all" to "bothered a lot." Scores are tallied to measure overall somatic severity, where higher numbers indicate a greater level of physical distress. It is easy to hand out in busy clinics since it takes very little time to finish. Clinicians use it to track changes over time or screen for somatisation disorders without needing long interviews. This makes it a practical choice for guiding ongoing patient care and adjusting treatment plans.
The PHQ-15 can be scored using one main approach: calculating the total symptom severity score based on patient responses. You will tally up ratings for the 15 somatic symptoms. Each item gets a 0 for not bothered at all, 1 for bothered a little, or 2 for bothered a lot. When you add them up, the total ranges from 0 to 30. Scores of 5, 10, and 15 represent cutoffs for mild, moderate, and severe somatic symptom severity. It is a handy way to track how physical complaints impact a patient's daily life in the clinic.
