The symptoms of PTSD are particularly believed to occur predominantly in children. We believe that Yogo teachers, who play a role in maintaining and promoting the health of children, are expected to provide appropriate support for children with a tendency for PTSD. In this study, we investigated the tendency for PTSD in students at University, as well as self-esteem related to depression and anxiety. Furthermore, we clarified the relationship between PTSD and self-esteem and examined the support provided by Yogo teachers. As a result, it was found that the higher the tendency for PTSD, the lower the self-esteem. We believe that the onset of PTSD causes a decline in memory ability and attentional function, which interferes with one’s life and leads to self-denial, resulting in a decline in self-esteem among those with a high tendency for PTSD. These results suggest that Yogo teachers should provide support to prevent the onset of PTSD in child students due to accidents, incidents, natural disasters, etc., as well as support to prevent the decline in self-esteem associated with the onset of PTSD.展开更多
