Beck Anxiety Inventory (BAI)

About: This scale is a self-report measure of anxiety. Items: 21


Internal consistency for the BAI = (Cronbach’s a=0.92)
Test-retest reliability (1 week) for the BAI = 0.75 (Beck, Epstein, Brown, & Steer, 1988)


The BAI was moderately correlated with the revised Hamilton Anxiety Rating Scale (.51), and mildly correlated with the Hamilton Depression Rating Scale (.25) (Beck et al., 1988).

The total score is calculated by finding the sum of the 21 items. Score of 0-21 = low anxiety
Score of 22-35 = moderate anxiety
Score of 36 and above = potentially concerning levels of anxiety
