Governance, Boundaries & Ethical Use

Construct Boundaries & Interpretive Limitations

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. Items 1 and 3 describe difficulty adhering and are reverse-scored so a higher total consistently reflects greater adherence.
