Purpose : Anxiety disorder and depressive disorder are often comorbid with each other, and the comorbidity is associated with poorer psychiatric outcome, resistance to treatment, increased risk for suicide, greater chance for recurrence. We aimed to investigate the comorbidity of anxiety disorder in Korea.
Method : Subjects were total of 867 depressed patients recruited CRESCEND-K multicenter trial. We used SCID (Structured Clinical Interview for DSM - IV) to find comorbidity of anxiety disorders in depressed patient.
Results : Of 867 patients, total 8.2% had anxiety disorder. Proportion of anxiety disorder Not Otherwise Specified was 3.5%, panic disorder was 1.7%, generalized anxiety disorder was 1.1%, post traumatic stress disorder was 0.9%, obsessive compulsive disorder was 0.6%, social phobia was 0.4%.
Conclusion : In this study, anxiety disorder in depression were measured at a low comorbidity rate in compare to previous studies. Selection bias, use of antidepressants at registration, severity of depression symptoms, and point of SICD administration seems to have affected these results. It is probable that comorbidity evaluation would be more precise if shorter, structured interviews such as M.I.N.I.-Plus were used during first clinical interview for depression diagnosis.
