背景：「失能」對個體影響甚大，同時還可能帶來家庭與社會的負擔。失能者面臨疾病或創傷的衝擊後，往往使 其社會參與受限，甚至日漸退縮，喪失生命活力。
目的：本研究目的旨在探討失能者社會參與情形及人口學與疾病特性、憂鬱及社會支持等與其社會參與之關係。
方法：採橫斷性研究，以高雄市某一醫學中心、兩家區域醫院及十二家長期照護機構之失能者為研究對象，採結 構性問卷，包括基本資料、憂鬱、社會支持及社會參與量表，以專家效度及内部一致性信度檢測，具良好 信效度；回收有效問卷100份。資料運用描述性及推論性統計方法進行分析。
結果：失能者社會參與平均值（標準差）為28.38(7.63)，屬中等程度。失能者年齡、居住狀況、教育程度及自我照 顧功能對其社會參與有顯著影響(p < .001);居住於長期照護機構、憂鬱及社會支持為社會參與重要解釋因 子，解釋變異量達44.8%。
結論/實務應用：由研究結果顯示，長期照護機構、憂鬱及社會支持為社會參與重要解釋因子。建議醫護人員宜儘 早瞭解所照護失能者社會參與的相關因素，並適時處理個案之憂鬱情緒、增進其社會支持，以避免失能者 社會參與受限。

Background: The restricted social participation of people with disabilities often results in reduced physical activity and a loss of vitality.
Purpose: This study explores the social participation of the disabled and its correlation with factors including demographics, illness, depression, and social support.
Methods: A cross-sectional study was used and study participants were chosen from 1 medical center, 2 regional hospitals, and 12 long-term care institutions in Kaohsiung City, Taiwan. Structured questionnaire surveys included scales that gathered data on demographics, depression, social support and social participation. Collected data were analyzed using descriptive and inferential statistics.
Results: The results showed that the mean score of social participation for participants was at the middle level (M = 28.38, SD = 7.63). Furthermore, age, living status, education level, and self-care function (p < .001) correlated significantly with social participation. The most important explanatory factors of social participation among people with disability were live in long-term care unit, depression, and social support; these factors explained 44.8% of the total variation.
Conclusions / Implications for Practice: Study results demonstrate that the social participation of people with disabilities is significantly affected by living in long-term care institution, having depression, and receiving social support. We suggest that medical and nursing personnel should work to better understand the factors
that significantly influence the social participation of people with disabilities and provide timely social support to encourage increased social participation.
