The purpose of this study was to examine the difference in social skills between "people with high social anxiety and high social passivity" and "people with high social anxiety and low social passivity" to clarify what social skills were necessary for the former. In addition, social skill was grasped from two aspects; one was used in a specific situation, and the other was used in general communication scenes. The results of this investigation using a sample of 174 undergraduate and graduate students showed the following: 1) In terms of social skills used in general communication scenes, "people with high social anxiety and high social passivity" were higher in emotional control skill scores than "people with high social anxiety and low social passivity", but the former had some difficulty in expressing their emotions. 2) In terms of social skills used in a specific situation, "people with high social anxiety and high social passivity" tended to set a goal of maintaining relationships in initial encounters.
