Outcome Measures

Primary Outcomes (1)

  • Mean Change From Baseline in Panic and Agoraphobia Scale (PAS) Total Score at the End of Treatment Phase

    Panic and Agoraphobia Scale has 13 items with a 5-point scale (range: 0 to 4). The total possible score is ranged from 0 to 52. The increasing value are considered worse outcome. The scale is grouped into 5 subscores (not including item U in total score): panic attacks ; agoraphobia/avoidance behavior ; anticipatory anxiety; disability; and health worries. Four point difference in reduction of the PAS total score has been identified as not clinically meaningful in the assessment of Panic Disorder symptomatology.
