[1] The Panic and Agoraphobia Scale (PAS) is primarily used for monitoring the efficacy of both medication and psychotherapy treatments of agoraphobia, as well as a screening tool for the disorder.
It is available in both self-rated and clinician-rated versions and the scale structure is compatible with DSM-IV and ICD-10 classifications.
In addition to the English version, translations are available in many languages, including French, German, Greek, Hebrew, Italian, Yiddish, Chinese, Thai, and others.
The PAS contains 13 questions (items) based on a five-point Likert scale (0 to 4).
Two or three items contribute each of five subscales, which cover the spectrum of agoraphobia symptom clusters: The Panic and Agoraphobia Scale has been shown to be an effective instrument for measuring the severity of agoraphobia and panic attacks, as well as monitoring treatment results.
