The Kessler Psychological Distress Scale scores, age, sex, health status, sleep satisfaction level, Great East Japan Earthquake experience, experience of losing a loved one, change in employment status, change in residence, and awareness of the impact of radiation on health were examined.

RESULTS

Psychological distress was significantly correlated with sex, health status, sleep satisfaction of, experience of losing a loved one, change in employment status, extreme anxiety regarding the acute health impact of radiation, and extreme anxiety regarding the impact of radiation on health in adolescents and the next generation.

LIMITATIONS

CONCLUSIONS

The results of the present study suggest that appropriate mental healthcare should be administered immediately following an earthquake to adolescents who have lost a loved one and experienced anxiety regarding the health impact of radiation following a nuclear accident.
