Governance, Boundaries & Ethical Use
Imported from the OpenScales open item-bank project. This specific digital implementation has not been independently clinically validated by PsiQ — scores are for self-reflection, research, and educational purposes only, and are not a diagnosis. Physical symptoms have many possible causes; a high score here is not itself a diagnosis of any condition.
