The PAS is a measure of the severity of illness in patients with panic disorder (with or without agoraphobia). It is available in both clinician-administered and self-rating formats. It contains 5 sub-scales: panic attacks, agoraphobic avoidance, anticipatory anxiety, disability, and functional avoidance (health concerns).
This questionnaire is designed for people suffering from panic attacks and agoraphobia. First, read the definition of “panic attacks” below; then rate the severity of your symptoms over the past week.
Panic attacks are sudden outbursts of anxiety, accompanied by one or more of the following symptoms:
- palpitations, pounding heart, or increased heart rate
- trembling or shaking
- dry mouth
- difficulty breathing
- feeling of choking
- chest pain or discomfort
- nausea or abdominal distress (churning in stomach)
- feeling dizzy, unsteady, faint, or light-headed
- feelings that objects are unreal (like in a dream)
- fear of losing control, “going crazy,” or passing out
- fear of dying
- hot flushes or cold chills
- numbness, or tingling sensations
Panic attacks develop suddenly and increase in intensity within about 10 minutes.
