APAIS is a short scale to assess patient’s preoperative anxiety. The instrument has 6 items rated by the patient on a 5-point scale, from 1 (not at all) to 5 (extremely). The anxiety score is calculated as the sum of items 1, 2, 4, and 5 and the need for information score is the sum of items 3 and 6. The score above 11 for the anxiety subscale is a sign that the patient is experiencing anxiety and the intervention to reduce anxiety is needed. The Anxiety subscale has a Cronbach’s α of 0.86. It has acceptable concurrent validity compared to State-Trait anxiety inventory and good retest reliability.[10]
