Objective - This article describes the short-term and at 6 months follow-up results of an intensive cognitive-behavioural group treatment on subjects affected by Panic Disorder with or without Agoraphobia (DSM IV criteria). Design and Setting - We studied a group of 22 subjects treated in the public Centro Psico Sociale of Zogno (Bergamo) and valuated them with self-rated instruments inherent the life satisfaction (SF/36) and symptoms and ament (PAAAS; MSPS, STAI-X1, STAI-X2). The results indicate significant improvements at the end of treatment and at a 6 months follow up. Conclusions - We are studying the long-term results with others follow up valuations. The most important result, anyway, is the demonstration that also in an Italian public mental health centre, as in many foreign countries, is possible to treat patients affected by Anxiety Disorders with effectual and relatively low cost tecniques and that is possible to introduce objective results indicators in the routinary clinical activity.
