Factors associated with caregiver strain among mothers and fathers of children with advanced cancer.

Objectives: To characterize caregiver experiences in the context of advanced pediatric cancer by identifying individual (i.e., demographic factors, stress) and family context factors (i.e., family roles, social support) associated with caregiver strain.

Methods: Families of children (ages 5-25) with advanced cancer (i.e., physician-estimated prognosis < 60%, relapsed/refractory disease) were recruited from a large children's hospital. Mothers (n = 55; 87% White) and fathers (n = 30; 83% White) reported on their caregiver strain, cancer-specific stress, general stress, social support, division of 7 family roles (e.g., medical care of ill child, household chores), and their satisfaction with each role.

Results: Parents reported moderate caregiver strain, cancer-specific stress, and general stress, and high social support and satisfaction with family roles. Fathers reported family roles were shared equally, whereas mothers reported either sharing roles or completing them independently. When accounting for income and partnership status, greater caregiver strain for mothers was associated with greater general stress, greater satisfaction with family roles, and lower social support. For fathers, greater caregiver strain was associated only with greater cancer-specific stress.

Significance of results: In the context of advanced pediatric cancer, fathers may experience caregiver strain as cancer-specific stress increases, whereas mothers' strain may depend on broader family and social factors. Psychosocial providers should address general and cancer-specific stress within families, and provide resources for enhancing mothers' social support. Additional research is needed with larger, more diverse samples to inform future intervention approaches.
