초록
본 연구는 정상 집단과 불안장애 집단을 대상으로 KASIR의 총점을 비교한 첫 번째 연구로, 불안민감성이 정상 집 단에 비해 불안장애 집단에서 모두 높게 나타난다는 사실 을 확인하였다. 또한 불안민감성이 불안장애 집단 내에서는 통계적으로 유의미한 차이가 나타나지 않는다는 사실을 확 인함으로써, 불안민감성이 넓은 의미에서 다양한 불안장애 에 대한 취약성을 반영한다는 가설을 지지하고 있다. 마지 막으로, 불안민감성의 하위 요인들과 각각의 불안장애 사이 의 관련성을 확인하였으며, 임상에서 KASI-R의 하위 요인 이 불안장애를 변별하는 데 도움을 줄 수 있다는 가능성을 확인하였다. 이를 명확하게 하기 위해, 추후 연구에서는 임 상환자 집단을 대상으로 장기적, 종단적 연구가 필요할 것 으로 사료된다.
Abstract
Objectives The present study aimed to compare anxiety sensitivity among anxiety disorder groups, and to examine the relationships between lower-order factors of anxiety sensitivity and each anxiety disorder. Methods Three hundred and twenty four normal control subjects and 212 patients with anxiety disorders were enrolled in this study. All subjects completed a psychometric assessment package including the Korean Anxiety Sensitivity Index-Revised (ASI-R) test. Statistical analysis of the two groups was performed using the Mann-Whitney U test, and comparison of anxiety sensitivity among the anxiety-disorder groups (panic disorder-PD, general anxiety disorder-GAD, social phobia- SP, obsessive-compulsive disorder-OCD) was investigated using Kruskal-Wallis test. Results All anxiety disorder groups showed higher total scores of the ASI-R than did the normal control group (Z=-13.724, p<.001), and the mean total score of the ASI-R in the panic disorder group was the highest among the anxiety disorder groups. The mean score of each lower-order factor of the ASI-R in each anxiety disorder group was higher than that of the normal control group and there were statistically significant differences in fear of cardiovascular symptoms (PD,GAD>SP,OCD), fear of respiratory symptoms (PD>GAD, SP,OCD), and fear of publicly observable anxiety reactions (SP>PD,OCD) among the anxiety disorder groups. ConclusionZZThese results suggest that anxiety sensitivity reflects vulnerability to anxiety disorders, and that lower-order factors of the ASI-R may help in the differential diagnosis of anxiety disorders.
