As a severity measure, the PHQ-9 score ranges from 0 to 27, because each of the 9 items can be scored from 0 ("not at all") to 3 ("nearly every day"). Easy-to-remember cutpoints of 5, 10, 15, and

If the score is 3 or greater, major depressive disorder is likely. Patients who screen positive should be further evaluated with the PHQ-9, other diagnostic instruments, or direct interview to determine whether they meet criteria for a depressive disorder. How to Score PHQ-9 Scoring Method for Diagnosis Major Depressive Syndrome is suggested if: Of the 9 items, 5 or more are circled as at least “More than half the days” Either item 1a or 1b is positive, that is, at least “More than half the days” Minor Depressive Syndrome is suggested if: Scoring Method. Scores range from 0 to 27. In general, a total of 10 or above is suggestive of the presence of depression. Listed below are PHQ-9 totals, the levels of depression that they relate to, and suggested treatment for each level of depression. Scoring Scores of 5, 10, and 15 are taken as the cut-off points for mild, moderate and severe anxiety, respectively. When used as a screening tool, further evaluation is recommended when the score is 10 or greater. Using the threshold score of 10, the GAD-7 has a sensitivity of 89% and a specificity of 82% for GAD. It is

The overall scores obtainable in PHQ-9 range between 0 (no depression symptoms present) to 27 (severe depression symptoms). The cut off points are at 5, 10 and 20, with scores above 10 with a sensitivity of 88% and 88% specificity. The following table explains the first hand indications in every score category.

• A l symptom severity scoretota (range = 17-85) can be obtained by summing the scores from each of the 17 items that have response options ranging from 1 “Not at all” to 5 “Extremely”. • The gold standard for diagnosing PTSD is a structured clinical interview such as the Clinician-Administered PTSD Scale (CAPS). Scoring Method. Designed for use in primary care settings, the PHQ-4 consists of the first two items of the PHQ-9 and GAD-7 respectively, and constitute the two core DSM-IV items for major depressive disorder and generalized anxiety disorder, respectively. The PHQ-2 and GAD-2 each ranges from a score of 0 to 6 (with 2 items in each scale scored PHQ-9 modified for Adolescents (PHQ-A) Name: Clinician: Date: Instructions: How often have you been bothered by each of the following symptoms during the past two weeks? For each symptom put an “X” in the box beneath the answer that best describes how you have been feeling. (0) Not at all (1) Several days (2) More than

The best cut-off points for the PHQ-9 and PHQ-2 summary scores were ≥11 (sensitivity 0.76, specificity 0.81) and ≥3 (sensitivity 0.76, specificity 0.82), respectively. No relationship was observed between the age and PHQ-9 scores. Conclusion The PHQ-9 and PHQ-2 were useful instruments for screening for major depressive disorders.

A PHQ-9 score ≥ 10 has a sensitivity of 88% and a specificity of 88% for major depression.1Since the questionnaire relies on patient self-report, the practitioner should verify all responses. Psychometric Properties n The diagnostic validity of the PHQ-9 was established in studies involving 8 primary care and 7 obstetrical clinics. n PHQ scores ≥ 10 had a sensitivity of 88% and a specificity of 88% for major depression. n PHQ-9 scores of 5, 10, 15, and 20 represents mild, moderate, moderately severe and severe depression.1 1. Add together column scores to get a TOTAL score. 4. Refer to the accompanying PHQ-9 Scoring Card to interpret the TOTAL score. 5. Results may be included in patients’ files to assist you in setting up a treatment goal, determining degree of response, as well as guiding treatment intervention. PHQ-9 SCORING CARD FOR SEVERITY DETERMINATION The overall scores obtainable in PHQ-9 range between 0 (no depression symptoms present) to 27 (severe depression symptoms). The cut off points are at 5, 10 and 20, with scores above 10 with a sensitivity of 88% and 88% specificity. The following table explains the first hand indications in every score category.
