有關智能障礙者居住決策事宜，家屬往往扮演重要的角色。本研究採質性研究立意取樣，透過提供社區居住服務的社福團體代為邀約，邀請連續使用社區居住服務三個月之智能障礙者其主要聯絡家屬參與研究，最終共計訪談20位智能障礙者家屬，瞭解其當初選擇使用社區居住服務的過程。研究結果發現，多數研究參與者係透過正式支持系統的引薦得知社區居住服務，至於選擇使用社區居住服務的原因，除是希望訓練智能障礙者獨立及擁有交友圈外，也不乏因現實考量而選擇此種居住型態，而在決策過程中，正式與非正式資源的支持，對研究參與者最終選擇社區居住服務有所影響。基於上述研究結果，本研究建議加強宣導社區居住服務措施，以及強化以家庭為中心的服務。

In terms of the housing issue of people with intellectual disabilities, their family members often play a critical role in speaking up and decision-making. In a qualitative study, the use of purposeful sampling invites family members with intellectual disabilities who have used community housing services for three consecutive months to participate in the research through the invitation of social welfare organizations in community housing services. Qualitative interviews with family members of people with intellectual disabilities were conducted in this study to understand the process of choosing to use community housing services at first. In this study, the family members of 20 with intellectual disabilities were interviewed. The study revealed that most respondents learned about community housing services through referrals from formal support systems. In addition to training individuals with intellectual disabilities to be independent and forge their friendships, many have also chosen this type of living based on practical considerations, and the support of formal and informal resources plays a critical role in choosing the process of community housing. Because of the above, this study recommends increasing the promotion of community housing services and strengthening family-centered services.
