本研究整合利用質性與量化等多元度量工具及資料蒐集方法（包括行為觀察、適應行為量表、訪談等）檢測自然環境體驗對泛自閉症兒童之社會互動行為的影響。結果顯示，部分個案在自然體驗介入初期，雖會因個人身體健康及情緒狀況，影響目標行為表現，但多數個案於中、後期探索自然元素的主動性提升、能增加在自然環境中的遊戲型態及多元性；且個案因接觸自然環境後情緒穩定，加上自然體驗經驗的累積，其與他人溝通、分享的社會互動行為表現，皆有正向提昇。個案能將相關的正向社會互動行為模式內化並延伸至後續的日常生活中。相關結果可供特殊教育機構與特殊孩童家庭成員，做為其執行輔導與教養特殊需求兒童工作時參考。

In this study, qualitative and quantitative measurement tools and multiple data collection methods (i.e., behavioral observation, the Adaptive Behavior Scale, and interviews) were employed to investigate the effect that experiences in the natural environment have on the social interactive behaviors of children with autism spectrum disorders. The results revealed that during the mid- and late stages of the natural environment experience, the majority of the participants exhibited improvements in both their initiative to explore the natural elements and the capacity to adapt to diverse games in a natural environment. During the early stage of the experience, the participants’ health and emotional status were found to affect their performance in terms of their social interactive behavior. After making contact with the natural environment and accumulating related experiences, the emotional stability of the majority of the participants improved, with improvements in the observed performance of socially interactive behaviors, such as interpersonal communication and sharing. It is anticipated that in the future, the participants will be able to internalize the positive social interactive behavior patterns learnt during this study, and apply this knowledge to their daily lives. The results of this study may serve as reference for special education institutions or family members of children with autistic spectrum disorders during counseling and parenting.
