Beck anxiety inventory: psychometric characteristics in a sample from the clinical Spanish population

ABSTRACT

Even though the Beck Anxiety Inventory (BAI) is one of the most popular instruments to assess anxiety today, only limited data is available about its psychometric characteristics and normative values in clinical Spanish populations. A study was conducted to test the psychometric characteristics of a Spanish adaptation of the Beck Anxiety Inventory (BAI) in a sample of 918 outpatients being treated at a community mental health center in Spain. Results confirmed the adaptation’s high internal consistency (∝ = .91), substantial test-retest reliability at 8-10 weeks (r = .84, p < .01), and satisfactory convergent validity with the Anxiety (r = .86, p < .01), Somatization (r = .81, p < .01), Obsessive compulsive (r = .60, p < .01), and Phobic Anxiety (r = .63, p < .01) dimensions of the SCL-90-R, and with the Anxious Thoughts Inventory (r = .57, p < .01). Gender differences in BAI scores did occur, so normative values appear separately for each gender (AU)
