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. Item 2 (average hours slept per night) is a descriptive item bucketed into ranges for this platform's option-based format; the original instrument treats it as a free-entry number and does not include it in the summed subscale scores.
