As a severity measure, the PHQ-9 score can range from 0 to 27, since each of the 9 items can be scored from 0 (not at all) to 3 (nearly every day). An item was also added to the end of the diagnostic portion of the PHQ-9 asking patients who checked off any problems on the...
In addition, as the PHQ-9 is scored between 0 and 27, in instances where the recorded PHQ-9 score was outside of the plausible range, these scores were omitted from analysis. Statistical analysis was conducted using Stata version 15.1. Sensitivity analysis Follow-up time was broken in 6 ...

However, given that the PHQ-9 covers the whole range of diagnostic features of major depression, it is likely that it would also be responsive to antidepressants with different modes of action, for example, tricyclic antidepressants. Finally, our study was an open-label, noninterventional, post-...
The PHQ-9 seems to be similarly sensitive but may be less specific for younger patients than for older patients; a cut-off score of 10 or above can be used regardless of age.. Conclusions PHQ-9 sensitivity compared with semistructured diagnostic interviews was greater than in previous ...
The summed scores range from 0 to 27. Various cut-off scores allow for the determination of different degrees of depression. A study on the Thai PHQ-9 in the general Thai population reported that a summed score of 9 or greater signified a major depressive disorder, with a sensitivity of ...
may also overestimate the number of participants having clinical depression across a range of conditions [75,76], which might require the use of an even higher PHQ-9 cut-off score. When interpreting our study, it is important to be aware that the PHQ-9 and the M.I.N.I. measure ...
