This depression screening by phq 2 calculator takes the figures you already have and applies the relationship behind depression screening by phq 2 calculations for you, giving major depressive disorder positive predictive value, any depressive disorder positive predictive value and major depressive disorder likelihood ratio from little interest or pleasure in doing things and feeling down, depressed or hopeless.
What Is the Depression Screening by PHQ 2 Calculator?
The depression screening by phq 2 calculator gives you an estimate of major depressive disorder positive predictive value, any depressive disorder positive predictive value and major depressive disorder likelihood ratio based on little interest or pleasure in doing things and feeling down, depressed or hopeless.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the Depression Screening by PHQ 2 Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.

A Worked Example
Working through an example, with little interest or pleasure in doing things set to 0, feeling down, depressed or hopeless set to 0, the calculator returns phq-2 score of 0, and major depressive disorder likelihood ratio of 0, and any depressive disorder likelihood ratio of 0. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out major depressive disorder positive predictive value?
Enter little interest or pleasure in doing things and feeling down, depressed or hopeless. The calculator then works through the relationship and reports major depressive disorder positive predictive value, any depressive disorder positive predictive value and major depressive disorder likelihood ratio.
What does the depression screening by phq 2 actually calculate?
It takes little interest or pleasure in doing things and feeling down, depressed or hopeless and converts them into major depressive disorder positive predictive value, any depressive disorder positive predictive value and major depressive disorder likelihood ratio using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter little interest or pleasure in doing things?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
