The subjects were 233 outpatients with panic disorder (99 males and 134 females) diagnosed according to DSM\u2010IV criteria. Sixty\u2010three patients met the criteria for panic disorder without agoraphobia, and 170 met the criteria for panic disorder with agoraphobia. Patients with agoraphobia showed a significantly longer duration of panic disorder and higher prevalence of generalized anxiety disorder. However, there were no significant differences in prevalence of major depressive episodes, in current severity of panic attacks, or in gender ratio between the two groups. The second aim of the present study was to investigate the effects of onset age and sex differences on the development of agoraphobia within a half\u2010year. The subjects were divided into two groups according to their self\u2010report: patients who did or did not develop agoraphobia within 24\u2003weeks of onset of panic disorder. A total of 40.6% of the patients developed agoraphobia within 24\u2003weeks of the onset of panic disorder, and onset age and sex differences had no robust effect on the development of agoraphobia within 24\u2003weeks.<\/jats:p>","DOI":"10.1111\/j.1440-1819.2005.01430.x","type":"journal-article","created":{"date-parts":[[2005,12,1]],"date-time":"2005-12-01T16:43:12Z","timestamp":1133455392000},"page":"639-643","source":"Crossref","is-referenced-by-count":16,"title":["Panic disorder with and without agoraphobia: comorbidity within a half\u2010year of the onset of panic disorder"],"prefix":"10.1111","volume":"59","author":[{"given":"MITSURU","family":"KIKUCHI","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"RYUTAROU","family":"KOMURO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HIROSHI","family":"OKA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"TOMOKAZU","family":"KIDANI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"AKIRA","family":"HANAOKA","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YOSHIFUMI","family":"KOSHINO","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,12]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005053-199405000-00007"},{"key":"e_1_2_5_3_2","first-page":"17","article-title":"The long\u2010term treatment of panic disorder","volume":"59","author":"Davidson JR","year":"1998","journal-title":"J.
