Spitzer, Janet W.B. Williams and Kurt Kroenke in 1999.<\/p>\n<h2><strong>About the PHQ-9<\/strong><\/h2>\n<p>The PHQ-9 combines depression diagnostic criteria from the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) with other leading major depressive symptoms. The key diagnostic symptom criteria adapted from the DSM-IV includes:<\/p>\n<ul>\n<li>Two typical signs of\u00a0depression: anhedonia (referring to the inability or reduced ability to experience pleasure) and depressed mood;<\/li>\n<li>Cognitions (e.g. guilt\/worthlessness and suicidality\/thoughts of death); and<\/li>\n<li>Physical symptoms (e.g. change in appetite, difficulty sleeping and concentrating, feeling tired\/slowed down or restless).<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p>Each of the 9 questions rate the frequency of the symptoms, which factors into the severity index.<\/p>\n<p>Clinicians and clinical leaders will often ask about\u00a0the differences between the PHQ-9 and other depression scales. In comparison to the other commonly used depression scales (BDI, HAD-D, QIDS), the\u00a0confidence intervals are quite similar, meaning they have all demonstrated reliability, validity, and are responsive to change. The PHQ-9 has a particularly <a href=\"https:\/\/www.apa.org\/pi\/about\/publications\/caregivers\/practice-settings\/assessment\/tools\/patient-health\" rel=\"nofollow noopener\" target=\"_blank\">high validity<\/a> score, such that when PHQ-9 scores were above 10, the measure was shown to have a sensitivity of 88% and a specificity of 88% for Major Depressive Disorder\u2014meaning that a score above 10 was a good indication that a diagnosis of depression would occur. Each of the major depression scales have their differences, although the PHQ-9 and BDI-II in particular tend to measure relatively equal levels of severity and track symptom change in a similar manner. The PHQ-9 is often preferred to other comparable assessments due to its brevity, which makes it easy to integrate into research or practice, and helps promote high completion rates.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Patient Health Questionnaire 9 (PHQ-9) Recommended\u00a0frequency: Every 2 weeks Download Sample Summary The Patient Health Questionnaire 9 (\u201cPHQ-9\u201d) is a multi-purpose measure used to identify and monitor depression severity.
