Association of psychological vulnerability factors to post-traumatic stress symptomatology in mothers of pediatric cancer survivors.

The current study investigated whether individual differences in coping style, lifetime experience of traumatic events, perceived social support, and perceived social constraints were associated with symptoms of post-traumatic stress among 72 mothers of children who had successfully completed cancer treatment. Results suggested that more perceived social constraints and less perceived belonging support were associated with significantly more post-traumatic stress symptomatology, and this association was present after controlling for the effects of child age. Monitoring coping style and lifetime traumatic events were not significantly predictive of post-traumatic stress symptoms. The results of this study indicate that a sense of belonging to a social network as well as comfort expressing cancer-related thoughts and feelings to friends and family may play a key role in mothers' long-term adjustment to this extremely difficult life experience.
