Abstract: | Although deficits in attentional control have been linked to posttraumatic stress disorder (PTSD), the mechanism that may account for this association has not been fully elucidated. The present study examined rumination as a mediator of the relationship between attentional control and PTSD symptoms. Veterans with PTSD and trauma-exposed veterans without PTSD completed measures of attentional control, rumination, and PTSD symptom severity. As predicted, the findings showed that veterans with PTSD reported significantly lower levels of attentional control than veterans without PTSD. Veterans with PTSD also reported significantly higher levels of rumination than veterans without PTSD. Subsequent analysis of the total sample revealed that the relationship between attentional control and PTSD symptom severity was accounted for by excessive rumination. Attentional control may contribute to PTSD symptoms through excessive rumination. Attentional control and rumination may be important targets for PTSD interventions. |
