Based on your answers to its 4 items, you'll get a single overall score (0-16) showing how strongly asthma is affecting your daily life right now.

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. RAND also provides an IRT-based T-score conversion for this instrument that this platform does not implement; only the simple sum score (0-16) is calculated here. A 12-item short form (RAND-IAQL-12) with finer detail is also available on this platform.
