Are you generally anxious, or only in specific situations? The STAI distinguishes state anxiety (how you feel right now) from trait anxiety (how you tend to feel generally). 40 items, about 10 minutes. The STAI (Spielberger et al., 1983) separates temporary anxiety states from long-standing anxiety tendencies, used widely in both clinical and research settings.

Two kinds of anxiety

Anxiety isn't just one thing. State anxiety is how you feel right now — tense, nervous, worried. Trait anxiety is how you generally tend to feel across situations and over time. The STAI measures both.

The State-Trait Anxiety Inventory (STAI) has 40 items total: 20 for state anxiety and 20 for trait anxiety. Each item is rated on a 4-point scale.

What the scores mean

Low scores indicate low anxiety; high scores indicate high anxiety.

About this scale

Charles Spielberger developed the STAI in 1970, with the revised Form Y published in 1983. It's still a common anxiety measure in research and clinical practice.

  • Internal consistency: α = 0.86–0.95
  • Test-retest reliability: r = 0.65–0.86 (state), r = 0.73–0.86 (trait)
  • Completion time: 10–20 minutes
The STAI is particularly useful because it distinguishes between temporary anxiety states and stable anxiety tendencies. This distinction can help determine whether intervention should focus on immediate coping strategies or longer-term patterns.
