This study was carried out to develop a Korean language version of Zung´s self-rating anxiety scale(SAS) from august, 1994 to September, 1996. The subjects consisted of 205 normal control subjects from the general population group, and 97 subjects with anxiety disorders. These 97 subjects were chosen from a group by the structured clinical interview for DSM-IV of in patients and out patients. Both normal control subjects and anxiety disorder subjects were drawn utilizing a cluster of sampling methods.
In order to analyze the data on anxiety scores, Pearson´s product moment correlation coefficient method was carried out, as well as reliability, factor analysis and discrimina;it function analysis, utilizing the SPSS/PC+ program.
The results obtained were - as follows:
The mean average of the total anxiety scores were 32.36 + 6.35 for the normal control subjects and 50.53 + 7.67 for anxiety disorder subjects.
Test-retest reliability(coefficient r=0.98, p < 0.001), and internal consistency(coefficient r=0.96, p < 0.001) were satisfactory.
Factor analysis using oblique technique rotation yielded four factors.
_ The . normal control subjects scored higher concerning the symptoms such as sweating, restlessness, apprehension, insomnia and dyspnea, and lower for faintness, mental disintegration, paresthesia, dizziness and .tremor.
