Panic disorder is a common and debilitating disorder that has a prevalence rate of 3-5% in the general population. Cognitive-behavioural interventions have been shown to be an efficacious treatment for panic, although a limited number of studies have examined the effectiveness of such interventions implemented in everyday clinical settings. The aim of the following pilot study was to examine the feasibility of a brief group cognitive-behavioural intervention carried out in a clinical setting. Salient issues in determining feasibility include: representativeness of patient group treated, amount of significant clinical change displayed and resources required to carry out the intervention. A small sample of GP-referred patients displaying panic symptoms completed a 2-week intensive cognitive-behavioural intervention. Results collected post-intervention revealed significant clinical reductions in panic, anxiety and depressive symptoms and marked improvement in mobility. These improvements were maintained at 12-month follow-up. Outcomes supported the feasibility of a brief group cognitive-behavioural intervention for GP-referred patients. Implications of these results are discussed in terms of implementing effective treatments in everyday clinical practice and developing a stepped care approach to treating panic symptoms.
