gVAS — generalized Visual Analog Scale (horizontal variant)

How intense was the anger you felt?

This scale captures the entire range of how intense experiences can possibly be. The right end (100) represents the strongest sensation you could ever imagine experiencing — the absolute maximum intensity across all sensory modalities. The left end (0) is the complete absence of any sensation.

Why gVAS? The gVAS uses the same quasi-logarithmically spaced labels as the gLMS but in a horizontal layout. It is simpler to implement (especially in Qualtrics) and pilot data suggest it produces equivalent results.
