State-Trait Anxiety Inventory (STAI)

The State-Trait Anxiety Inventory (STAI) is a validated assessment of anxiety, both in a temporary condition (state) and as a more long-standing quality (trait). It includes items on current feelings and feelings in general of contentness, tension, unrest, confusion, nervosity, and worry, among others.

In TRAILS, the STAI was used to measure subjective stress-reactivity before and after the Spatial Orienting Task, Bangor Gambling Task, Trier Social Stress Test, and Startle Reflex Task.
