Objectives: In this study, the authors did a retrospective study to examine effectiveness
and attrition of brief group cognitive behavior therapy (CBT) for panic
disorder (PD) routinely practiced in the psychiatric outpatient clinic at a general
hospital. Methods: A total of 53 patients (37 females and 16 males, with mean age
of 44.72 years) had accepted the 8-weekly 1.5 hour group CBT separately during
2005-2010. The data of effectiveness and dropout variables were reviewed from
documents of patients’ medical and group records as well as their psychological
measures. Results: The brief group CBT was found to have significant improvements
in patients’ disaster belief and anxiety level at the end of treatment (p <
0.01), and to decrease their severity of panic attacks (p < 0.01), agoraphobic avoidance
(p < 0.01), fear of body sensation (p < 0.05), and depression symptoms (p <
0.05) at 6-month follow-up. But high attrition rate of 45.3% was found. The signifi
cant negative predictor of attrition was recent panic attacks recorded before the
fi rst group sessions (p < 0.05). Recent panic attacks motivated them to complete
group sessions. Reasons of their discontinuing treatment included practice problems
and treatment being not needed. Conclusion: These study results suggest the
brief group CBT for PD is an effective and feasible treatment in the psychiatric
outpatient clinic. Strategies to prevent and to reduce attrition, such as setting up
recruitment criteria, doing orientation interview, or adapting alternative modes of
delivering CBT should be considered in the future.
