How is the PHQ-9 scored?
PHQ-9 Depression Severity. This is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of ―not at all,‖ ―several days,‖ ―more than half the days,‖ and ―nearly every day,‖ respectively. PHQ-9 total score for the nine items ranges from 0 to 27. Using the MHP reinterview as the criterion standard, a PHQ-9 score ≥10 had a sensitivity of 88% and a specificity of 88% for major depression. PHQ-9 scores of 5, 10, 15, and 20 represented mild, moderate, moderately severe, and severe depression, respectively. The Patient Health Questionnaire (PHQ)-9 is the major depressive disorder (MDD) module of the full PHQ. Used to provisionally diagnose depression and grade severity of symptoms in general medical and mental health settings. At the initial visit for depression care the PHQ-9 is used to assist with diagnosis and identification of problem symptoms. At the follow-up visit, the PHQ-9 is used to measure treatment response and identify specific symptoms that are not responding. Depression Severity: 0-4 none, 5-9 mild, 10-14 moderate, 15-19 moderately severe, 20-27 severe. The following guidelines are recommended for the interpretation of scores: 0–7 for normal or no anxiety, 8–10 for mild anxiety, 11–14 for moderate anxiety, and 12–21 for severe anxiety.
What is a good PHQ-9 score?
PHQ-9 Score Interpretation A PHQ-9 score total of 0-4 points equals “normal” or minimal depression. Scoring between 5-9 points indicates mild depression, 10-14 points indicates moderate depression, 15-19 points indicates moderately severe depression, and 20 or more points indicates severe depression. ShareThe PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression. 0–9 = normal, 10–19 = mild depression, 20–30 = severe depression. Usefulness of PHQ-9 in primary care to determine meaningful symptoms of low mood: a qualitative study. The Patient Health Questionnaire—9 (PHQ-9) and the Generalized Anxiety Disorder Questionnaire– 7 (GAD-7) are short screening instruments used for detection of depression and anxiety symptoms in various settings, including general and mental health care as well as the general population.
What is a positive PHQ-9 score?
The PHQ-9 total score ranges from 0 to 27 (scores of 5–9 are classified as mild depression; 10–14 as moderate depression; 15–19 as moderately severe depression; ≥ 20 as severe depression) [30]. Conclusion: In addition to making criteria-based diagnoses of depressive disorders, the PHQ-9 is also a reliable and valid measure of depression severity. These characteristics plus its brevity make the PHQ-9 a useful clinical and research tool. The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression: n The PHQ-9 incorporates DSM-IV depression diagnostic criteria with other leading major depressive symptoms into a brief self-report tool. Sensitivity and specificity analyses showed that the PHQ-9 is sensitive but not specific at capturing depressive symptoms when compared to clinician diagnoses whereas the GAD-7 was neither sensitive nor specific at capturing anxiety symptoms. Its purpose is not to establish final diagnosis or to monitor depression severity, but rather to screen for depression. Patients who screen positive should be further evaluated with the PHQ-9 to determine whether they meet criteria for a depressive disorder. Several participants thought that not all relevant depressive symptoms were covered by thePHQ-9. It did not allow them to adequately express changes in their symptoms. Missing items include the tendency to withdraw from people, lack of libido and the sudden onset of an inability to cope at work.
How to calculate PHQ-9 score?
Scores are calculated based on how frequently a person experiences these feelings. Each “not at all” response is scored as 0; each “several days” response is 1; each “more than half the days” response is 2; and each “nearly every day” response is 3. The sum value of these responses gives you your total score. Scores are calculated based on how frequently a person experiences these feelings. Each “not at all” response is scored as 0; each “several days” response is 1; each “more than half the days” response is 2; and each “nearly every day” response is 3. The sum value of these responses gives you your total score. The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of “not at all,” “several days,” “more than half the days,” and “nearly every day,” respectively, and then adding together the scores for the seven questions. GAD-7 total score for the seven items ranges from 0 to 21. The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of “not at all,” “several days,” “more than half the days,” and “nearly every day,” respectively, and then adding together the scores for the seven questions. GAD-7 total score for the seven items ranges from 0 to 21. Scores of 5, 10, 15 and 20 on the PHQ-9 represent thresholds of mild, moderate, moderately severe and severe depressive symptoms, respectively. A 5-point change is clinically significant. A score of less than 10 suggests a partial response, and a score of less than 5 represents remission. Scores represent: 0-5 = mild 6-10 = moderate 11-15 = moderately severe. 16-20 = severe depression. GAD-7 Anxiety Severity.
How accurate is PHQ-9?
We found that PHQ-9 sensitivity and specificity were both 85% compared with semistructured interviews. Sensitivity and specificity analyses showed that the PHQ-9 is sensitive but not specific at capturing depressive symptoms when compared to clinician diagnoses whereas the GAD-7 was neither sensitive nor specific at capturing anxiety symptoms. PHQ-9 showed good reliability and validity, and high adaptability for patients with MDD in psychiatric hospital. It is a simple, rapid, effective, and reliable tool for screening and evaluation of the severity of depression. The 9-question Patient Health Questionnaire (PHQ-9) is a diagnostic tool introduced in 2001 to screen adult patients in a primary care setting for the presence and severity of depression. In conclusion, the PHQ-9 is a widely used tool in primary care for diagnosing depression and determining depression severity. For practitioners, it can provide an appealing numerical and “objective” diagnosis (Tavabie & Tavabie, 2009). Internal reliability for the PHQ-9 is reported as “excellent” with a Cronbach’s α of 0.89 and 0.86 in the primary care and obstetrical clinical studies, respectively.
How accurate is the PHQ-9?
We found that PHQ-9 sensitivity and specificity were both 85% compared with semistructured interviews. The PHQ-9 showed a high degree of internal consistency (ICC = 0.88) and test-retest reliability (correlation = 0.94). With respect to construct validity, it showed a clear association with functional status measurements, sick days and number of consultations. Regarding severity, PHQ-9 comprises five categories, where a cut-off point of 0–4 indicates no depressive symptoms, 5–9 mild depressive symptoms, 10–14 moderate depressive symptoms, 15–19 moderately-severe depressive symptoms, and 20–27 severe depressive symptoms [25]. ShareThe PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression.
How do you score Phq questionnaire?
PHQ-9 scores can be used to plan and monitor treatment. To score the instrument, tally the numbers of all the checked responses under each heading (not at all=0, several days=1, more than half the days=2, and nearly every day=3). Add the numbers together to total the score on the bottom of the questionnaire. The PHQ-9 should be administered at least quarterly after initial positive screen (defined as a score of 10 or greater). b. For enrollee/members scoring 5-9 on the PHQ-9, a repeat PHQ-9 should be completed as clinically indicated or at a minimum of at least annually. 89. Criteria validity was established by conducting 580 structured interviews by a mental health professional. Results from these interviews showed that individuals who scored high (≥ 10) on the PHQ-9 were between 7 to 13.6 times more likely to be diagnosed with depression by the mental health professional.
