In the original article (Beck, Epstein, Brown, & Steer, 1988), the BAI has no exact instructions nor labels on the middle points of its Likert Scale.
"The respondent is asked to rate how much he or she has been bothered by each symptom over the past week on a 4-point scale ranging from 0 (Not at all) to 3 (Severely—I could barely stand it). The items are summed to obtain a total score that can range from 0 to 63."
Some internet versions (https://www.gphealth.org/media/1087/anxiety.pdf) have instructions and a complete scale:
0 - Not at all
1 - Midly, but it didn't bother me much
2 - Moderately - it wasn't pleasent at times
3 - Severely - it bothered me a lot
Below is a list of common symptoms of anxiety. Please carefully read each item in the list. Indicate how much you have been bothered by that symptom during the past month, including today, by circling the number in the corresponding space in the column next to each symptom.
