Abstract
For many diagnosed mothers and their daughters, breast cancer is a shared experience. However, they struggle to talk about cancer. This is particularly true when the daughter is in adolescence or young adulthood, as they tend to be more avoidant, which is associated with poorer biopsychosocial outcomes. When daughters are their mother's caregivers, daughters' burden and distress are heightened. Young adult caregiving daughters (YACDs) are the second most common family caregiver and encounter more distress and burden than other caregiver types. Yet, YACDs and their diagnosed mothers receive no guidance on how to talk about cancer. Thirty-nine mother/YACD pairs participated in an online survey to identify challenging topics and strategies for talking about cancer, and to explore associations between openness/avoidance and psychosocial outcomes. YACDs and mothers reported the same challenging topics (death, treatment-related issues, negative emotions, relational challenges, YACDs' disease risk) but differed on why they avoided the topic. YACDs and mothers identified the same helpful approaches to navigate conversations (openness, staying positive, third-party involvement, avoidance). Avoidance was correlated with more distress whereas openness was correlated with better psychosocial outcomes. These results provide a psychosocial map for a mother-YACD communication skills intervention, which is key to promoting healthy outcomes.
