Association of alexithymic characteristics and posttraumatic stress responses following medical treatment for children with refractory hematological diseases.

Recent research has examined posttraumatic stress disorder (PTSD) following medical treatment for children with refractory hematological diseases such as leukemia. However, much remains unknown. This study examined the association of alexithymic characteristics on the manifestation of posttraumatic stress responses in 33 children with refractory hematological diseases. Of 33 children, 27 (81.8%) exhibited posttraumatic stress responses following medical treatment for refractory hematological diseases. The frequency of posttraumatic stress responses was significantly higher than with children who experienced severe flood disaster. Also, the severity of posttraumatic stress responses was significantly stronger than for children who experienced severe flood disaster. Moreover, children with refractory hematological diseases were more likely to exhibit alexithymic characteristics. The alexithymic characteristics were significantly and positively correlated with avoidance and emotional numbing among posttraumatic stress responses. The results suggest the possibility that alexithymic characteristics may be predictive of the manifestation of avoidance and emotional numbing among posttraumatic stress responses following medical treatment for refractory hematological diseases.
