Right now, or in general?

The STAI has two 20-item scales. One asks how you feel at this moment (state anxiety); the other asks how you generally feel (trait anxiety). It became one of the most widely used anxiety questionnaires.5

FORM Y-1 · STATE20 ITEMS · 1–4
"How do you feel right now?"
FORM Y-2 · TRAIT20 ITEMS · 1–4
"How do you generally feel?"
This is history, not a self-test.This page doesn't reproduce the inventory and can't assess your anxiety. If anxiety is getting in the way of your life, a doctor or mental-health professional can help.

One idea, two time frames

The inventory was designed as one set of questions that, with the right instructions, could target a particular kind of anxiety.1 Its 40 items split evenly between the two scales.5

StateY-1 · STAI-S
Feelings at a particular momentTemporary fear, tension and anxiety in a specific or recent situation.4Example item: "I am relaxed"6
TraitY-2 · STAI-T
How you generally feelA stable tendency to see situations as threatening and to react with anxiety as a habit.3Example item: "I feel satisfied with myself"7

Why the state score moves and the trait score doesn't

Give a fictional person a general tendency, then tap each day to change what happens. The "right now" score follows events; the "in general" score stays put.

The numbers back the distinction

If the two scales measure what they claim, trait scores should hold steady on retest while state scores drift. Spielberger's figures fit: test-retest correlations of .54 for the state scale and .86 for the trait scale.9

Low retest agreement would count against most tests. For a state scale it's intended, because moods change.

State scaler = .54
Trait scaler = .86

1964, 1970 or 1983?

1964First constructedOne source says Spielberger, Gorsuch and Lushene built the original form in 1964.10
1970The first manualManual for the State-Trait Anxiety Inventory, Consulting Psychologists Press, Palo Alto. The early version was called Form X.8
1983Form YRevised to its current form, with the state and trait scales labelled Y-1 and Y-2. The manual was later published by Mind Garden.5

Most sources credit the 1970 manual to Spielberger, Gorsuch and Lushene.8 One also lists Vagg and Jacobs as 1970 collaborators, although they appear on the 1983 Form Y manual.5,7
