Purpose
The purposes of this study were to determine whether there were differences in the cancer pain experience between patients and family caregivers (FCGs) and to explore the associated factors that influence cancer pain experience congruence.
Methods
A multicenter cross-sectional study was conducted. A total of 410 patient-family caregiver dyads completed face-to-face surveys, including information about basic characteristics, the Patient Pain Questionnaire (PPQ), and the Family Pain Questionnaire (FPQ). The difference in cancer pain experience between patients and family caregivers was analyzed using a paired
t
test. Indicators for the congruence of cancer pain experience were analyzed using the chi-square test and two independent-sample
t
tests for bivariate analysis and multivariate binary logistic regression analysis.
Results
Of the patients, 57.1% were men, and 60.7% perceived moderate performance status. The majority of the family caregivers was female (54.9%). The mean (SD) score on the pain experience subscale was 4.82 (1.66) for 410 patients and 5.02 (1.66) for 410 family caregivers. The difference was significant (
P
< 0.01). Additionally, 87 (21.2%) dyads were in the congruent group, and 323 (78.8%) dyads were in the incongruent group. Patients’ self-perceived moderate performance status (OR = 2.983,
P
< 0.01) and family caregivers’ pain knowledge (OR = 1.171,
P
< 0.05) were the main factors influencing the congruence of cancer pain experience.
Conclusion
The findings of this study indicate that family caregivers reported significantly worse cancer pain experiences than patients. Family caregivers’ pain knowledge was a primary influencing factor. It is suggested that educational interventions aimed at teaching family caregivers and patients how to communicate their pain experience and improving the knowledge of family members regarding pain and its management may help in aligning their perceptions and thereby contribute to better quality of life and pain management outcomes.
