“…The questionnaire consisted of 20 items that evaluated how the participants felt at the time of responding to each item. Note that 10 items were associated with the anxiety-present (items 3, 4, 6, 7, 9, 12, 13, 14, 17, 18) and the remaining items were associated with the anxiety-absent (items 1, 2, 5,8,10,11,15,16,19,20). The intensity of the participants' feelings was rated on a 4-point Likert scale: (I) not at all, (II) somewhat, (III) moderately so, and (IV) very much so.…”
