研究背景: 隨著乳腺癌患者存活率的不斷上升及其存活時間的不斷延長，癌病倖存已成為一個重要的慢性疾病管理問題。之前在該領域的研究主要集中於生活質量的測量。然而，癌病倖存研究應該超出這一範疇而更好地去瞭解乳腺癌倖存者的真實體驗。癌病倖存是一個新興而複雜的概念，它包含了動態的、多維的以及社會文化的觀點。但是，衛生專業人員受限於現有的知識未能為中國大陸乳腺癌患者的長期倖存做好準備。 / 研究目的: 本研究目的是從中國大陸女性的視角詳盡闡述乳腺癌倖存者的親身體驗。具體研究目標包括：1）乳腺癌倖存者的生活質量；2）與乳腺癌倖存者生活質量相關的因素；3）乳腺癌患者的倖存體驗；4）社會人口學及臨床學特徵對於乳腺癌倖存體驗的影響；5）建立一種與文化相關的概念模型用以解釋中國婦女乳腺癌患者的倖存體驗。 / 研究方法: 本研究採用混合研究方法，分兩個階段進行。先是定量法（第一階段），其次是定性法（第二階段）。第一階段是對乳腺癌倖存者其生活質量及相關因素進行橫斷性調查。測量工具包括生活質量-癌症倖存者量表及社會支持問卷簡表。該階段的調查結果將指導第二階段的目的性抽樣並建立半結構式訪談計劃。第二階段是對選定倖存者進行深入訪談以探究她們的癌症倖存體驗。採用內容分析法對訪談數據的潛在及顯性內容進行分析。然後對不同定義組中的定性數據進行比較，探索社會人口學及臨床學特徵對乳腺癌倖存體驗的影響。最後對定量和定性數據進行對比和比較，以確定並探討癌病倖存體驗的組成元素和模型開發。 / 研究結果：在完成第一階段的100位倖存者中，平均年齡為53.75 歲 (SD=7.27)，治療完成後存活時間的中位數為44 個月 (四分位範圍=23-61)。總體生活質量平均值為6.55，範圍3.68 - 8.89。在身體分量表中顯示生活質量最高值，而在靈性分量表找到其最小值。多元回歸分析表明，存活期的長短、對社會支持的滿意度以及家庭年收入與生活質量均顯著相關。 / 29位倖存者完成了第二階段的研究。結果顯示用於描述倖存經驗的七個範疇，包括：體驗令人痛苦的症狀；與不確定性進行抗爭；在女性特質及性行為上的改變；忍受社會壓力；被關照和支持；反思和個人成長；生存並向前發展。定性數據的比較顯示，對於存活時間低於5年，或者家庭年收入較低，亦或感知的生活質量較低的女性，她們傾向於報告負面的倖存經驗。通過提取定量和定性階段上主要的研究結果建立一個概念模型，用以解釋中國女性是如何理解乳腺癌倖存經驗的。它表明，乳腺癌倖存經驗在本質上是多維的。治療完成後，乳腺癌患者在生活變化上會有消極與積極的雙重性，會對生活質量評估產生影響。此外，乳腺癌倖存經驗也不是一成不變的。它是一個動態的應對過程，具有幾種策略以應對癌症導致的生活變化。 / 研究結果：本研究對中國文化背景下乳腺癌倖存經驗提供了證據。本研究全面而深入的瞭解乳腺癌患者倖存經驗，並為進一步發展測量工具以及具備文化敏感性的心理干預提供了基礎，以解決中國女性的倖存經驗的問題。 / Background: With the increasing survival rate and length of survival in breast cancer, cancer survivorship has become an important chronic illness management issue. Previous studies in this area mainly focus on appraisal of quality of life (QOL). However, cancer survivorship studies should go beyond QOL to better understand breast cancer survivor’s experience of living with the disease. Cancer survivorship appears as an emerging but complex concept incorporating dynamic, multidimensional, and socio-cultural perspectives. Little information exists addressing breast cancer survivorship experience in mainland China that impedes health professionals’ ability to deliver quality of cancer care. / Aim: To develop an understanding of breast cancer survivorship experience from the perspective of mainland Chinese women. Specific objectives included exploring 1) women’s perceived QOL; 2) factors associated with women’s QOL; 3) women’s perception of breast cancer survivorship experience; 4) the influence of socio-demographic and clinical characteristics on the women’s perception of their survivorship experience after breast cancer; and 5) to develop a culturally relevant conceptual model to explain Chinese women’s breast cancer survivorship experience. / Methods: A mixed methods study with two phases was conducted, quantitative approach (Phase One) followed by qualitative approach (Phase Two). Phase One was a cross-sectional survey on Chinese breast cancer survivors to investigate their QOL and its associating factors. Instruments included Quality of Life -- Cancer Survivor Scale and six-item Social Support Questionnaire. Findings in this phase contributed to inform the purposive sampling and develop a semi-structured interview schedule for Phase Two. In-depth interviews on selected survivors were conducted to explore their perceptions of cancer survivorship experience. Content analysis was used to analyze both latent and manifest meaning of interview data. Comparisons of qualitative data across defined groups were made to explore the influence of socio-demographic and clinical characteristics on breast cancer survivorship experience. Quantitative and qualitative data were compared and contrasted to identify and explore elements in cancer survivorship experience and model development. / Results: Among 100 survivors who completed Phase One, the mean age was 53.75 years (SD=7.27), and the median length of survivorship since completion of treatment was 44 months (IQR=23-61). The mean overall QOL was 6.55, with a range of 3.68 -8.89. The highest QOL was found in the physical subscale, and the lowest in the spiritual subscale. Multivariate regression analysis identified that length of survivorship, satisfaction with social support, annual household income were significantly associated with QOL. / Twenty-nine survivors completed Phase Two. Seven categories emerged describing the survivorship experience included experiencing distressful symptoms; struggling with uncertainty; alterations in femininity and sexuality; living with social stress; being cared for and supported; reflections and personal growth; and surviving and moving forward. Comparisons of qualitative data revealed that women with less than five years of survivorship, or low annual household income, or low perceived QOL tended to report negative survivorship experience. A conceptual model was developed by drawing the key findings of quantitative and qualitative phases to explain how Chinese women perceive the breast cancer survivorship experience. It reveals that breast cancer survivorship experience is multidimensional in nature, with a duality for the negative and positive aspects of life changes after completion of treatment, contributing to influence appraisal of QOL. Furthermore, breast cancer survivorship experience is not static but a dynamic coping process with several strategies for dealing with life changes that result from cancer. / Conclusions: The study provides evidence of several components of breast cancer survivorship within Chinese cultural context. This offers a comprehensive and insightful understanding of the experience after surviving breast cancer, and a basis for further inquiry for developing an instrument and culturally sensitive psychosocial intervention to address Chinese women’s survivorship experience. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Cheng, Huilin. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 252-283). / Electronic reproduction.
