초록

Purpose

This study is to determine actor and partner effects of stress coping on quality of life (QoL) of cancer patients and their primary caregivers using an actor-partner independence model (APIM).

Methods

The subjects of this study were adults aged 19 years and over who visited a hospital. They were diagnosed with cancer and were treated with chemotherapy, radiotherapy, and hemato-poietic stem cell transplantation. 137 patients with cancer and 137 caregivers were included in the study.

Results

Cancer patient stress had a direct effect on their stress coping (β=.42, p=.004). Primary caregiver stress also had a direct effect on their stress coping (β=.41, p<.001). Factors significantly affecting cancer patients’ QoL were patient stress (β=-.14, p=.002), stress coping (β=.24, p<.001), and primary caregiver stress coping (β=.11, p=.021). Factors significantly affecting primary caregiver QoL were primary caregiver stress (β=-.22, p<.001) and their stress coping (β=.14, p=.009).

Conclusion

In order to improve the quality of life of cancer patients and caregivers, it is necessary to consider cancer patients and caregivers as a unit when constructing intervention programs for stress management.
