Patient‑caregiver relationship in cancer fatigue and distress. A dyadic approach

It has been shown that a reciprocal relationship between cancer patients and their family caregivers positively decreases distress in both. In this context we tried to explore the role of relationship reciprocity in the dyad members’ symptoms of fatigue and distress (anxiety and depression). Specifically, we aimed to assess the implications of relationship reciprocity testing the link between the various measurements of patient Quality of Life (QoL) and caregiver burden and the other measures of fatigue, distress, and relationship reciprocity. Moreover we aimed to examine the inter-relatedness of patients’ and caregivers’ relationship reciprocity with their own as well as fatigue and distress of the dyads. A convenience sample of 545 adult cancer patients and their caregivers from 15 cancer centers were examined using a cross-sectional design. Participants were administered dyadic measures (fatigue, distress, relationship reciprocity) and individual measures (patients’ QoL and caregivers’ burden). Patients’ QoL and caregivers’ Burden were associated with fatigue, distress and relationship reciprocity. The Actor-Partner Interdependence Model (APIM) revealed that each person’s relationship reciprocity was associated with their own distress and fatigue (actor effects); only caregivers’ relationship reciprocity was associated with patients’ fatigue and distress (partner effects). These findings suggest that the implication of the caregiving relationship for fatigue symptoms in both - patients and caregivers - appears worth of investigation.
