초록
본 연구는 유방암 생존 여성이 치료 종료 후에도 경험하게 되는증상인 갱년기 증상, 피로, 인지기능장애, 삶의 질 정도를 확인하고,네 변수 간의 상호관련성과 갱년기 증상과 피로가 삶의 질에 미치는 효과에서 인지기능장애의 매개효과 있는지를 확인한 경로분석연구이다. 연구 결과 갱년기 증상과 피로는 상관성이 매우 높았으며, 갱년기 증상과 피로는 인지기능장애 정도에 유의한 영향을 미치는 것으로 확인되었다. 피로는 삶의 질에 매우 큰 영향을 미치는것으로 확인되었으나, 갱년기 증상이 삶의 질에 미치는 영향과 인지기능장애 정도가 삶의 질에 미치는 효과 모두 미미한 것으로 확인되었다. 또한, 본 연구에서는 갱년기 증상이 삶의 질에 미치는 효과에서인지기능장애의 매개효과와 피로가 삶의 질에 미치는 영향에서 인지기능장애의 매개효과는 아주 미미한 것으로 확인되었다. 본 연구를 위해 대상자를 편의추출 하였으므로 그 결과를 유방암 생존 여성 전체에게 일반화하는데는 제한이 있을 수 있겠다. 그러나 본 연구는 유방암 생존 여성이 치료 후에도 경험하게 되는 증상들에 대한 인과관계를 확인하기 위한 경로분석 연구로서 증상 클러스터의세부이론 개발에 도움이 될 것이다.
Abstract
Purpose: The purpose of this study was to test hypothetical model of quality of life (QOL) in breast cancer survivors and to test themediating effects of cognitive dysfunction. Methods: This study was conducted from December 1st, 2013 to February 28th, 2014. 164breast cancer survivors were recruited from A, D, and Y city in Korea. The instruments used in this study were climacteric symptoms,fatigue, cognitive dysfunction, and the QOL scales. Data were analyzed using descriptive statistics, correlation, and pathway. Results:Cognitive dysfunction was directly affected by climacteric symptoms and fatigue. QOL was directly affected by fatigue, However climactericsymptoms and cognitive dysfunction did not effect on QOL directly. Impact of climacteric symptoms on QOL, mediatingeffect of cognitive dysfunction was not confirmed. In addition, effect of fatigue on the QOL, the mediating effect of cognitive dysfunctionwas not. Conclusions: Effects of climacteric symptoms on QOL was not mediated by cognitive dysfunction, Furthermore effectsof fatigue on QOL was not mediated by cognitive dysfunction.
