Associations between perceived stress and quality of life in gynaecologic cancer patient-family caregiver dyads

Purpose: This study aims to explore the level of stress perceived and quality of life (QOL) by gynaecologic cancer (GC) patients and family caregivers' dyads. Methods: In this cross-sectional study, 86 dyads were recruited from the gynaecological oncology department of a general hospital in Taichung City, Taiwan. The patients and family caregivers completed a sociodemographic information sheet, the Perceived Stress Scale, and the Taiwanese version of World Health Organization Quality of Life-BREF questionnaire. Data were analysed using descriptive statistics and Pearson's correlations. This study used the actor-partner interdependence model (APIM) with distinguishable dyads to examine the effect of patients' and caregivers' perceived stress on QOL in patient-caregiver dyads. Results: GC patients' and caregivers' level of QOL was influenced by their own stress level (actor effect). Caregivers' stress was statistically negatively associated with the patients' QOL (partner effect); however, there were no partner effect from GC patients to caregivers. Both patients and family caregivers with higher perceived stress had poorer QOL. Therefore, we identified that stress has some level of actor and partner effects on QOL in GC patient-family caregiver dyads. Conclusions: Family caregivers' stress displayed both actor and partner effects within the first year of the cancer diagnosis; therefore, patient-and caregiver-based interventions, such as stress reduction strategies, should be developed to enhance patients' and caregivers' QOL and stress management ability.
