孩子死亡是家庭的重大事件，對喪子女父母而言是一種椎心之痛，對倖存手足也是強烈的失落，然而，許多研究都把焦點放在喪子女父母的悲傷，而忽略了倖存手足的傷痛及調適歷程。本研究採質性研究的深度訪談，共訪談了七位喪手足女性成人，進行回溯性資料收集，以了解倖存手足者之悲傷反應，及影響倖存手足悲傷調適的因素，並探討成年面對手足死亡的悲傷調適歷程。本研究結果，摘要如下：一、喪手足成人的悲傷反應：包含有情緒、認知、生理與行為等層面，與一般喪親者並無太大的不同。二、喪手足成人悲傷調適的方式：分為正向積極與負向消極之調適方式。喪手足成人採取正向積極調適方式來接受手足死亡的事實，並適應沒有逝者的新生活，而負向消極方式則多半以逃避方式不願面對手足死亡的事實。三、影響喪手足成人悲傷調適的因素：包括了與已逝手足的互動關係、自喪手足成人的支持系統、其他重要他人的死亡、手足死亡時的微笑表情、喪葬儀式、輔導志工的專業訓練等正向因素；家人的悲傷反應、台灣文化下的喪葬習俗等負向因素；以及中性的因素有喪手足成人的人格特質；宗教或民間信仰。四、悲傷經驗對喪手足成人的影響：分別為對生死態度的影響；個性的改變；教導孩子如何面對死亡；重新定位自己的角色；容易觸景傷情；終其一生活在因手足死亡引起的自責之中；人生（生命）觀的改變；家庭結構與互動模式的改變等。依據上述的研究結果，研究者針對喪手足女性成人、諮商實務工作及未來的相關研究提出具體建議。

Howerver, many researchers put their study focus on the pain of those parents who loss a child but neglect the feeling of the other children in the family and how they adjust themselves.
