State-Trait Anxiety Inventory for Adults™

 

Author: Charles D. Spielberger

The State-Trait Anxiety Inventory for Adults™ (STAI-AD) is the definitive instrument for measuring anxiety in adults. It clearly differentiates between the temporary condition of “state anxiety” and the more general and long-standing quality of “trait anxiety”. It helps professionals distinguish between a client’s feelings of anxiety and depression. The inventory’s simplicity makes it ideal for evaluating individuals with lower educational backgrounds. Adapted in more than forty languages, the STAI is the leading measure of personal anxiety worldwide. The STAI has forty questions with a range of four possible responses to each. Note that the STAI Form X (the previous form) is available from Mind Garden to match pre-1983 research.

Scales:

The State-Trait Anxiety Inventory Form Y is the definitive instrument for measuring anxiety in adults. The STAI clearly differentiates between the temporary condition of "state anxiety" and the more general and long-standing quality of "trait anxiety."

Scale: State Anxiety (S-Anxiety)
The essential qualities evaluated by the STAI S-Anxiety scale are feelings of apprehension, tension, nervousness, and worry. Scores on the STAI S-Anxiety scale increase in response to physical danger and psychological stress, and decrease as a result of relaxation training.

Scale: Trait Anxiety (T-Anxiety)
On the STAI T-Anxiety scale, consistent with the trait anxiety construct, psychoneurotic and depressed patients generally have high scores.

More information about S-Anxiety:

  • Evaluates how respondents felt at a particular time in the recent past and how they anticipate they will feel either in a specific situation that is likely to be encountered in the future or in a variety of hypothetical situations.
  • Is found to be a sensitive indicator of changes in transitory anxiety experienced by clients and patients in counseling, psychotherapy, and behavior-modification programs.
  • Assesses the level induced by stressful experimental procedures and by unavoidable real-life stressors such as imminent surgery, dental treatment, job interviews, or important school tests
  • For screening high school and college students and military recruits for anxiety problems, and for evaluating the immediate and long-term outcome of psychotherapy, counseling, behavior modification, and drug-treatment programs.
  • Proven useful for identifying persons with high levels of neurotic anxiety and for selecting subjects for psychological experiments who differ in motivation or drive level.

From the Manual:

"State and trait anxiety are analogous in certain respects to kinetic and potential energy. S-Anxiety, like kinetic energy, refers to a palpable reaction or process taking place at a given time and level of intensity. T-Anxiety, like potential energy, refers to individual differences in reactions.

"Potential energy refers to differences in the amount of kinetic energy associated with a particular physical object, which may be released if triggered by an appropriate force. Trait Anxiety implies differences between people in the disposition to respond to stressful situations with varying amounts of S-Anxiety. But whether or not people who differ in T-Anxiety will show corresponding differences in S-Anxiety depends on the extent to which each of them perceives a specific situation as psychologically dangerous or threatening, and this is greatly influenced by each individual’s past experience."
