| Summary: | <h4>Background</h4>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.<h4>Methods</h4>Longitudinal data from parents of children receiving cancer therapy were used. PTSS were assessed using the PTSD Checklist Civilian Version at one week (T1), two (T2) and four months (T3) after diagnosis. Mediation analyses for multiple mediators were conducted for mothers (n = 122) and fathers (n = 121), respectively. The mediation model tested the assumption that the PTSS symptom clusters hyperarousal and avoidance mediated the relationship between re-experiencing and dysphoria.<h4>Results</h4>For fathers, none of the hypothesized mediators were significant. For mothers, hyperarousal mediated the relationship between re-experiencing and dysphoria, but avoidance did not.<h4>Conclusions</h4>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. |
