“…These measures were used successfully in our previous work with this population and with parents of children with cancer. 13,22 Guided by the multivariable model for the impact of chronic illness in the family we adapted in our previous work [22][23][24] and current empirical evidence with parents facing pediatric cancer and SCT, 3,7,13,22 we also examined the association between parental psychological distress and parental age; disease (diagnosis) and treatment variables (radiation history), and child's age, health status and behavior. Again, based on previous reports on mothers facing childhood cancer, 12,13,18,19,21 we hypothesized that (a) psychological distress will decrease over time for both mothers and fathers; (b) mothers will report more distress than fathers; (c) younger parents will report greater distress, and given that mothers are typically the primary caregiver; (d) child's disease, treatment, health status and behavior will have greater impact on maternal than paternal outcomes.…”
