Why do some members keep silent, although the group counseling is based on interaction? Is this a way of participation or is oral participation too difficult as a skill to actualize in a group? This study handles the issue of silence and its reasons, which group leaders frequently face and sometimes have difficulty coping with in non-voluntary training groups. The data for the study were collected from the reports of 61 members in four distinct counseling groups. The groups were led simultaneously by two leaders who are specialized in individual and group counseling. The data were analyzed using content analysis. As a result, it was found that silence because of personal characteristics was the major cause of silence, and that it appears to be there are reasons for silence other than the ones specified in the relevant literature.
