Screeners and tools

Validated questionnaires and attention tasks that score instantly and explain your result in plain language. Your answers stay in your browser unless you choose to save them.

Check how you're doing

Pick what sounds like you. Each opens the matching questionnaires.

Tools inside the notes

Interactive tools that live inside a note, next to the evidence they're built on.

Health tools, beyond psychiatry

These are outside my specialty. I built them because people ask me about these things as a physician, because I find them useful myself, and because the science is fun to share. Each one is built on published evidence and cites it, and none of them replaces your own doctor, who knows your history and can examine you. If a number here worries you, take it to them.
