Posttraumatic Stress in Parents of Children Diagnosed with Cancer: Hyperarousal and Avoidance as Mediators of the Relationship between Re-Experiencing and Dysphoria

Increased understanding of the relationships between different symptom clusters involved in posttraumatic stress symptoms (PTSS) could guide empirical research and clinical practice. The objective of the present study was to investigate whether hyperarousal and avoidance mediated the relationship between re-experiencing and dysphoria in parents of children diagnosed with cancer. = 121), respectively. The mediation model tested the assumption that the PTSS symptom clusters hyperarousal and avoidance mediated the relationship between re-experiencing and dysphoria.For fathers, none of the hypothesized mediators were significant. For mothers, hyperarousal mediated the relationship between re-experiencing and dysphoria, but avoidance did not.Results suggest that hyperarousal is important for the development of dysphoria in mothers, supporting use of interventions targeting such symptoms in the early and ongoing period following the child’s diagnosis
