Study Summary

This is a 5-year double blind, randomized, controlled, trial conducted at three treatment sites, aimed at showing the acute and longer-term effects of DCS augmentation of exposure-based CBT for panic disorder relative to placebo augmentation. By demonstrating that DCS can enhance the results of even a brief treatment strategy, the investigators are seeking to validate an approach that fits well with the practice limitations and applications of CBT in effectiveness studies.

Primary Outcome

The percent change in PDSS score from baseline to the relevant assessment points is the continuous primary outcome measure. The PDSS consists of seven items, each rated on a 0 to 4 scale (0 denoting none, and higher ratings reflecting greater degrees of symptom severity; for a possible range in scores from 0 to 28). In the tabular data below we present the total scores (sum of items).
