Relationship between expression of gratitude by home-based care receivers and caregiver burden among family caregivers

Backgrounds: We focused on the frequency of “gratitude” expressed by home-based care receivers towards family caregivers before they were in the condition that needed care and investigated the relationship with caregiver burden. Methods: This cross-sectional online survey was completed by 700 family caregivers in Japan. Caregiver burden was assessed using the Zarit Burden Interview. Caregivers with a score of ≤ 19 were defined as having mild caregiver burden, those with a score of 20 to 38 as having moderate, and those with a score of > 38 as having severe. Additionally, caregivers were asked, “How often did you get a ‘thank you’ from your care receiver before they were in a condition that needed care?” Answers were scored using a 11-point Likert scale. Answers with scores 0-2 were defined as low frequency of gratitude, 3-6 as middle, and 7-10 as high. Results: Among all caregivers, 233 (33.3%), 229 (32.7%) and 238 (34.0%) accounted for having mild, moderate and severe caregiver burden, respectively. High frequencies of gratitude of 48.9%, 43.7%, and 39.1%, respectively, were concluded with a significantly higher rate in the mild than in the severe caregiver burden group (p = 0.03). The results of multinominal logistic regression analysis, even after adjusting for several factors, show that high frequency of gratitude was significantly associated with caregiver burden (p < 0.01, OR: 0.48, 95%CI: 0.28-0.81). Conclusions: We found the frequency of gratitude from the care receiver before they were in the condition that needed care was substantially associated with caregiver burden.
