OBJECTIVE: Caregivers of pediatric cancer patients are at risk for posttraumatic stress symptoms (PTSS). Previous literature has identified caregiver illness uncertainty as a predictor of PTSS, yet little is known about the mechanism by which illness uncertainty may affect PTSS. Rumination, or perseverations about the cause and consequences of an event, has been related to posttraumtic stress disorder in other populations. However, limited research of this relationship exists for pediatric cancer caregivers. Further, no studies have evaluated rumination in relation to illness uncertainty. The current study examined rumination in relation to illness uncertainty and PTSS in caregivers with children actively receiving treatment for cancer. It was hypothesized that rumination would be related to illness uncertainty and would mediate the relationship between illness uncertainty and PTSS.
METHODS: Caregivers (N = 59) completed the Parent Perception of Uncertainty Scale, Ruminative Responses Scale, and the Impact of Event Scale-Revised.
RESULTS: illness uncertainty was identified as a significant predictor of rumination (B = 0.148, p = .015), and rumination was a significant predictor of PTSS (B = 1.83, p < .001). Biased-corrected bootstrap regression analysis revealed that rumination mediated the relationship between illness uncertainty and PTSS (R2 = 0.53, p < .001).
CONCLUSIONS: Rumination was identified as a mediator between the relationship of illness uncertainty and PTSS. These findings underscore the importance of rumination in caregivers of children with cancer, as a potential construct for identifying caregivers at risk of PTSS, and as a possible mechanism for targeted intervention.
