擔任癌末病患的照顧工作會影響照顧者的生活品質。過去研究顯示家庭功能對於照顧者的負荷或是照顧滿意度都有影響；但對於生活品質的影響卻未知。因此本研究的目的有：（1）評估癌末病患照顧者的生活品質；（2）瞭解家庭功能向度與各個照顧者生活品質範疇的相關；（3）探討在不同生活品質範疇中最有預測力的家庭功能向度。
　　本研究設計採取橫斷式的相關性研究法。收集154位安寧病房中病患的主要照顧者，由其完成基本資料、家庭功能問卷以及生活品質量表。
　　結果顯示，與一般健康人相比較，主要照顧者的生活品質在生理健康範疇與心理範疇的得分較差。教育年數愈少的照顧者，在生理健康與環境範疇的得分愈差。使用逐步迴歸分析，對於生理健康範疇最有預測力的家庭功能向度為問題解決與溝通。在心理範疇為問題解決與獨立性向度。在社會關係範疇為凝聚力向度。在環境範疇為問題解決向度。在照顧範疇為獨立性向度。
　　家庭問題解決能力較佳，則照顧者在心理與環境範疇的生活品質較佳；家庭成員的獨立性較高，照顧者在心理與照顧範疇的生活品質較佳；而整體家庭凝聚力高，照顧者的社會關係生活品質較佳。因此在家庭功能方面較重要的預測變項為問題解決、凝聚力以及獨立性向度。未來在提升照顧者之不同生活品質範疇，可設計由這些不同的家庭功能加以介入。

　　Providing hospice care to terminal patients will affect the quality of life of caregiver. Family functioning is linked to caregiver’s burden and care satisfaction. However, the relationship between family functioning and the quality of life of caregiver in hospice is still unknown. This cross-sectional study was aimed to (1) evaluate the quality of life of caregivers in hospice; (2) examine the correlations between the subdomains of quality of life of caregivers and the dimensions of family functioning; (3) explore the important predictors of subdomains of quality of life in family functioning dimensions. One hundred and fifty-four primary caregivers of cancer patients in hospice were recruited as subjects and administered the demographic form, the Family Function Scale, and the Quality of Life Scale.
　　The caregivers had lower QOL scores in physical health and psychological domains compared to the norm of the healthy. The caregivers with less education got lower scores in physical health and environment domains. As to the physical health domain, the best predictor on family functioning was problem solving and communication. As to psychological domain, those were problem solving and independence. Regarding social domain, that was cohesion. Regard with environment domain that was problem solving dimension. With respect to caring domain that was independence.
　　The problem-solving ability of the family is better, and the quality of life of primary caregivers are better in psychological and environment domains. The independence of family members is higher, and the primary caregivers get better scores in psychological and caring domains. And the primary caregivers have better quality of life of social relationship domain in the family with higher cohesion. The results were helpful to identify factors of family functioning that were important for intervention to improve the quality of life of caregiver.
