[Study on clinical inventory scale of social phobia].

Social phobia is found to be a common neurosis in our country. The concept is too broad and ambiguous to accept it as a clinical unit. Therefore no scale of social phobia has been made. The author attempted to extract one factor to be named as scale of social phobia by factor-analysing 500 items of the TPI (Todai Personality Inventory). As a result the author could find out one factor with 50 items, which was inner consistent and valid enough to show its specificity to differentiate social phobia from control group and other psychiatric disorders. It was also proved to be highly sensitive and reliable scale on statistics. By following discriminant analysis of scoring maps between social phobia group and control group, the author could find out that patients with score over 24 points could be included in social phobia group. According to the classification hypothesis the author divided the subjects into several groups by the severity of the symptom and calculated scores at each group. It was found that there was no difference of score between these groups. It was thought that the scale showed common characteristics of social phobia with high validity and reliability. These psychological characteristics were namely lowered self-esteem, introversive character, inadequacy of expression of self, feeling of inferiority in interpersonal relationship and in group situation, in addition there were secondary depressive tendency and psychosis-phobia.
