This study aimed to evaluate the severity and the frequency of depressive and anxiety disorders observed in 317 inpatients who were admitted to two general hospitals in Pusan, Pusan National University Hospital and Markynoll Hospital from December, 1987 to May, 1988. The evaluation was done by using the method of Zung’ s Self-Rating Anxiety Scale and Self-Rating Depression Scale. The characteristics of anxiety and deprssion in general hosptial inpatients were compared with those of the healthy subjects and psychiatric patients with anxiety and depressive disorders. The changes of severity in anxiety and depression according to the demographic and other related factors which might influence on the emotional status of these patients were analyzed. The results were as follows; 1) The mean score of SAS in inpatients was 38.5 which was significantly higher than that of healthy subjects and lower than that of anxiety disorders. The mean score of SDS in inpatients was 44.6 and it was significantly higher than that of healthy subjects and lower than that of depressive disorders. 2) The authors suggests the score of 42 in SAS and 49 in SDS as the cut off score which distinguish clinical anxiety or depressive disorders from normal condition when considering the sensitivity(84.4 짯，88.0%) and specificity(81.1 %, 85.8%) and overall diagnostic power(82.1 짯, 86.5%). In that case, the 36.5^ and 37.2% of inpatients were included in anxiety and depressive disorders. 3) The characteristic feature of anxiety in inpatients was the more frequent occurrence of vigilance and scanning and of some of the autonomic symptoms and rarer occurrence of anxious mood and sensory symptoms. In the case of depression, the feature of retarded depression and vegetatiwe symptoms were more frequent and the depressed affect with agitation and ideational depression were rarer. 4) The severity of anxiety and depression was significantly higher in the female than male and in the group who have the negative prospect to recovery to their own illness than other groups. The severity of depression was also significantly higher in the lower income group than other groups.
