Impact of Uncertainty on the Quality of Life of Young Breast Cancer Patients: Focusing on Mediating Effect of Marital Intimacy

Abstract

Purpose: The purpose of this study was to examine the mediating effect of marital intimacy on the impact of uncertainty on the quality of life (QoL) of young breast cancer patients. Methods: This study used a pathway analysis with 154 young breast cancer cases in their early diagnosis stage at a medical center in Korea. Data were collected from November 2016 to February 2017 and analyzed using correlation analysis and pathway analysis. Results: Uncertainty, marital intimacy, and 4 sub-scales of QoL showed a significant correlation. Marital intimacy was directly affected by uncertainty (beta=-.39, p=.013) and 4 sub-scales of QoL were also affected by uncertainty. Among the 4 sub-scales of QoL, physical well-being (PWB) (beta=.17, p=.026), social well-being (SWB) (beta=.49, p=.010), and functional well-being (FWB) (beta=.38, p=.009) were affected by marital intimacy but emotional well-being (EWB) was not affected by it. The mediating effect of marital intimacy on the impact of uncertainty on QoL was confirmed. Marital intimacy showed a significant indirect effect on PWB (beta=-.07, p=.024), SWB (beta=-.19, p=.008), and FWB (beta=-.15, p=.005), and it means that marital intimacy has a partial mediating effect on the impact of uncertainty on PWB, SWB, and FWB. Conclusion: Effects of uncertainty on QoL was mediated by marital intimacy of young breast cancer patients in their early diagnosis stage. It suggests that marital intimacy needs to be considered in providing nursing intervention for young breast cancer patients.
