Before you ask

Common questions

The short version: educational, evidence-based, and never a substitute for professional care. Details on the right.

What does CAADRIA stand for?

The Cognitive, Affective And Developmental Research Insights Archive — the three pillars of psychological science (thinking, feeling, growing) in one library.

Are the self-checks real psychological tests?

They are educational versions built on open, validated research instruments. They can show you patterns worth reflecting on, but they are not clinical assessments and cannot diagnose anything.

Do you store my quiz answers?

No. Interactive checks run entirely in your browser. Nothing you answer is stored on our servers or sent anywhere.

Is this a substitute for therapy?

No. CAADRIA is an educational publication. If you are struggling, a qualified mental-health professional is the right person to talk to.

CAADRIA is an independent psychology publication. Our content is educational and is not a substitute for professional mental-health advice, diagnosis or treatment. If you are struggling, please reach out to a qualified professional.
