Most caregiving literature has focused on women, who have traditionally taken on caregiving roles. However, more research is needed to clarify the mixed evidence regarding the impact of gender on caregiver/patient psychological outcomes, especially in an advanced cancer context. In this paper, we examine gender differences in caregiver stress, burden, anxiety, depression, and coping styles, as well as how caregiver gender impacts patient outcomes in the context of advanced cancer. Eighty-eight patients with advanced cancer and their caregivers completed psychosocial surveys. All couples were heterosexual and most caregivers were women (71.6%). Female caregivers reported significantly higher levels of perceived stress, depression, anxiety, and social strain compared with male caregivers, and female patients of male caregivers were more likely to use social support as a coping style compared with male patients of female caregivers. These findings highlight the potential differences between male and female caregivers' needs and psychological health.
