Panic Disorder Severity Scale (PDSS)
The PDSS is a self report scale that provides operationalized ratings of DSM-IV panic disorder symptoms. The PDSS consists of seven items, each rated on a 5-point scale. The items are carefully anchored and assess panic frequency, distress during panic, panic-focused anticipatory anxiety, phobic avoidance of situations, phobic avoidance of physical sensations, impairment in work functioning, and impairment in social functioning. The scale can be administered in 5 to 10 minutes. It is a useful way of assessing overall panic disorder severity at baseline, and it provides a profile of severity of the different panic disorder symptoms. It is a good monitoring tool because it is brief and sensitive to change. This scale is meant for use after diagnosis.
