What is the PHQ 9 Depression Scale?

The PHQ-9 is the depression module, which scores each of the nine DSM-IV criteria as "0" (not at all) to "3" (nearly every day). It has been validated for use in primary care. It is not a screening tool for depression but it is used to monitor the severity of depression and response to treatment.

Similarly, you may ask, what is a high PHQ 9 score?

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.

Likewise, what is the difference between Phq 2 and PHQ 9?

The Patient Health Questionnaire (PHQ)-2 and PHQ-9 are commonly used and validated screening tools. The PHQ-2 has a 97 percent sensitivity and 67 percent specificity in adults, whereas the PHQ-9 has a 61 percent sensitivity and 94 percent specificity in adults.

Who can use the PHQ 9?

The PHQ 2 and 9 are appropriate to be used with individuals 12 years of age and older. Alternative screening tools have been developed and validated for use among special populations including youth and older adults.

How long does the PHQ 9 take to complete?

It is the 9-question depression scale from the Patient Health Questionnaire (PHQ). The results of the PHQ-9 may be used to make a depression diagnosis according to DSM-IV criteria and takes less than 3 minutes to complete.
