PURPOSE: Nasopharyngeal carcinoma (NPC) imposes significant psychosocial challenges on patients and their spouses, yet dyadic coping (DC) patterns and their determinants remain underexplored. This study aimed to assess DC levels and classify latent coping profiles among Chinese NPC patient-spouse dyads, and to identify factors associated with profile membership.
METHODS: A cross-sectional study recruited 223 NPC patient-spouse dyads in Guangzhou, China, from September 2022 to May 2023. Participants completed the Dyadic Coping Inventory, the Perceived Stress Scale, and the General Self-Efficacy Scale. Latent profile analysis was performed using Mplus 8.3. Hierarchical multinomial logistic regression with the Balanced group as reference was conducted to determine factors associated with profiles.
RESULTS: Three DC profiles were identified: Strained group (23.7%), Balanced group (65.5%), and Harmony group (10.8%). In Model 1, which excluded psychological factors, education level, intimate relationship quality, and source of income were significantly associated with profile membership. After adding psychological variables in Model 2, Strained group membership was associated with higher patient perceived stress, lower spouse self-efficacy, and poorer intimate relationship quality. Harmony group membership was associated with higher patient self-efficacy, higher patient perceived stress, and cancer stage.
CONCLUSIONS: These findings reveal the heterogeneity of DC patterns in Chinese NPC couples. Spouse self-efficacy protects against coping deterioration, while patient self-efficacy drives optimal harmony. Tailored interventions addressing gender-specific caregiving burdens and self-efficacy enhancement may improve dyadic coping in NPC populations.
