The Effect of Self-efficacy and Depression on Sense of Family Coherence in Cancer Patients Undergoing Chemotherapy and Primary Caregivers in Day Care Wards: Using the Method Actor-partner Interdependence Model

Purpose: The objective of this study was to determine the effects of self-efficacy and depression on the sense of family coherence in both cancer patients and their caregivers using the Actor-Partner Interdependence Model (APIM) analysis. Methods: A total of 274 patients were registered in the study, including 137 cancer patients who were undergoing chemotherapy in a day care ward and 137 primary caregivers. The data was collected from December 30, 2017 to July 30, 2018. Data were analyzed by the data analysis method using SPSS/WIN 20.0 (SPSS Korea Data Solution Inc) and AMOS 21.0 (SPSS Korea Data Solution Inc). Results: Self-efficacy of cancer patients had a direct effect on patient depression (β=-.24, p=.008). Self-efficacy of primary caregivers also had a direct effect on patient depression (β=-.51, p<.001). Factors significantly affecting cancer patient FSOC were cancer patient self-efficacy (β=.34, p<.001) and cancer patient depression (β=-.42, p<.001). Factors significantly affecting primary caregiver FSOC (Family Sense of Coherence) were cancer patient self-efficacy (β=.13, p=.026) and caregiver depression (β=-.29, p=.008). Conclusion: It is thought that self-efficacy and depression should be controlled to improve the family cohesion of cancer patients and their primary caregivers.
