PURPOSE: Breast cancer patients and their spouses often encounter emotional and physical challenges after surgery that shape how they perceive and manage the illness. Guided by the Self-Regulation Model, this study examined whether discrepancies in illness perceptions between partners predict their respective illness management behaviors three months after surgery.
METHODS: The descriptive longitudinal study was conducted with 295 breast cancer patient-spouse dyads recruited by convenience sampling between August 2021 and April 2023. Illness perceptions were assessed during hospitalization by using the Chinese version of the Revised Illness Perception Questionnaire for Breast Cancer (CIPQ-R-BC) (patient/spouse version), and illness management behaviors were measured three months later using the Cancer Self-Management Assessment Scale (CSMAS) for patients and the Caregiver Contribution to Cancer Patient Self-Management Scale (CC-CPSMS) for spouses. Paired t-tests were used to examine perception differences, and pathway analyses explored how these discrepancies predicted illness management behaviors.
RESULTS: Patients reported more negative emotions, less overall illness understanding, and confidence in their own efforts on the prognosis than their spouses. Discrepancies within patient-spouse dyads regarding timeline acute/chronic, treatment control, illness coherence, and timeline cyclical negatively predicted patients' illness management behaviors. Conversely, differences in perceived causes (metabolic comprehensive, environmental/immune, and uncontrolled factors) were the positive predictors of dyads' illness management behaviors. Additionally, greater dissimilarities in emotional representations were associated with poorer behavioral outcomes within dyads.
CONCLUSION: Perceptual discrepancies significantly influence illness management behaviors among breast cancer patient-spouse dyads. Dyadic interventions should target these gaps to improve outcomes. Targeting the perceptual gaps through dyadic, theory-based interventions may enhance the behavioral outcomes for both members of the breast cancer patient-spouse dyad during the oncology clinical settings.
