The purposes of this study were to examine effects of written disclosure of trauma on physical and mental functions and the written content for the individuals who have maintained posttraumatic stress reactions (PTSR). The written disclosure was structured to take distance from the reactions of the trauma. The participants were randomly assigned to three groups and received three times of writing sessions of 20 minutes once a week: the structured disclosure group(n=6), the free disclosure group(n=4) and the control group(n=4). Although it was found that the degree of the distancing in the structured disclosure group was higher than those of the free disclosure and control groups, these differences were not statistically significant. The changes were not seen in PTSR and other health indexes before and after disclosure. The written content analyses suggested that the more cognitive words increased, the better the health was in only the structured disclosure group. At the same time, the more cognitive words increased, the stronger the subjective degree of the distress was aroused. To summarize the above, it was suggested that the procedures to take the distance from the reactions of the trauma in this study were not enough. Further examination of the instruction of structuring is needed in future. The result of this study was discussed by theoretical framework
