Siblings of children with special needs often feel loneliness and jealous because their parents pay more attention to the children with disabilities and chronic illness, and feel burden to take care of the children with special needs. Although workshops with discussion activities to share their feelings and experiences, such as Sibshop, are reported to give a big impact for siblings, Japanese siblings were quiet during discussion activities demonstrated by Donald Meyer who developed Sibshop, maybe because Japanese are not accustomed to open discussion. The purpose of this study is to know the adequate modification of American workshop style and the impact of the workshop for the participants. Situation of discussion activities and the style of description of letters to lead the discussion are modified and small group discussion was carried prior to a big open discussion. After 4 hours workshops including games, discussions, and lunch, facilitated by an experienced instructor of adventure education, a questionnaire was conducted to 20 siblings aged from 7 to 13 years old. The results were as follows; 1) most siblings enjoyed listening to the stories of the other participants, 2) one third talked their concerns, 3) one third answered that their concerns were solved. These results suggest that the modified workshop is better not to aim to express nor solve siblings' concerns in Japan.
