Background
Created by Sally Cat and Riko Ryuki.
This adult PDA test comprises 50 questions relating to PDA and 39 questions asessing autism and social relatedness.
Although this is not a diagnostic tool, it can be used to help people better determine whether they are PDA.
Participation is entirely voluntary. No personal data is recorded.
Please note that the 50 PDA questions have not been devised by a professional, so will not be recognised as a diagnostic tool. They are a refined from an adult PDA test created by Riko Ryuki in 2016 from a PDA traits study carried out by Sally Cat that compared the ranks of 155 potentially distinct PDA traits (Sally Cat blog).
The 39 autism social relatedness questions are adaptated from the RAADS-R scale for autism, with the "normalising" questions altered so their scores don't need adjusting.
