The present study reports on the psychometric properties of the adaptation into Spanish of the Panic-Agoraphobic Spectrum Self-Report (PAS-SR). Drawing on a dimensional and longitudinal perspective of psychopathology, the PAS-SR was designed to measure a wide array of lifetime Panic-Agoraphobic features. Participants included outpatients with a DSM-IV-TR diagnosis of panic disorder (n = 26) or major depression (n = 28), and a normal control group (n = 41). Internal consistency and test-retest reliability were excellent for the total score, and moderate to excellent for most domains. Significant and high correlations between PAS-SR scores and instruments measuring similar constructs indicated good concurrent validity. The findings support the discriminant validity of the questionnaire. Patients with a diagnosis of panic disorder attained higher scores than normal controls on all domains, and displayed higher scores than patients with major depression on five of the eight domains. © 2005 Elsevier Inc.
