文採用橫斷式研究，探討台中某綜合醫院從2011年10月24日起至2012年9月27日就診之女性乳癌患者憂鬱症的盛行率、相關因子以及家庭支持度之關聯。研究採用Smilkstein家庭關懷量表評估家庭支持狀態、而憂鬱症的診斷則由受過訓練的研究護士使用結構式診斷問卷等方式進行。本研究共收集到300位研究個案，研究結果發現（1）乳癌患者之重度憂鬱症盛行率為8.33%，較國外大部分研究為低。（2）乳癌患者之憂鬱症與慢性疼痛相關。（3）乳癌患者之憂鬱症與患者是否接受放射治療、罹癌期間長短相關（4）乳癌患者之憂鬱症，與家庭關懷支持程度相關。本研究為原創性研究，獨立收集初級資料並分析，結果不僅可供心理腫瘤醫學領域參考、更可作為精神科相關研究之依據。研究限制方面，本研究為個案數稍嫌不足，且為一橫斷式研究，故無法判斷因果關係，未來可以考慮世代追蹤（cohort follow up）研究，當可獲得更為清楚之訊息。
This study is a cross-sectional study. We tried to explore the prevalence of major depressive disorder and related psychosocial factors in breast cancer patients. We also tried to evaluate the relationship between family support and the diagnosis of major depressive disorder. Data of the study are from breast cancer clinic of a general hospital in central Taiwan between 24, Oct, 2011 and 27, Sep, 2012. We used self-reported questionnaire: family APGAR index, to evaluate family support. We found that the prevalence of major depressive disorder of breast cancer patient is 8.33%, which is slightly lower than the previous studies. We also found the prevalence of major depressive disorder of breast cancer patient is related to chronic pain, the time elapsed since diagnosis, and the treatment of radiotherapy. We also confirmed the relationship between lacking of family support and major depressive disorder in breast cancer patients. Our result maybe renders a reference to health-providers and researchers, and may support more advanced studies in the field of cancer and psycho-oncology in the future. Limitation includes our study is cross-sectional, so causality can’t be clarify without more cohort follow study in the future.
