Abstract
The purposes of this study were to develop a ROS (Restorative Outcome Scale) Japanese edition (ROS-J), in order to investigate the psychological restorative effect (PRE) by the natural environment and to verify its validity and reliability, and to investigate the PRE of forest bathing in both secondary circumstance and short time for developing an easier stress reduction on our daily life. For the development of ROS-J, the two experiments (exp.1 and exp.2) were conducted by using total 357 (the number of valid response; 330) subjects. Also for verification of the PRE in off-site forest bathing, by using the ROS-J, further analysis was carried out by using the exp.1’s data consisted of total 312 (the number of valid response; 285) subjects. As a result, the both validity and reliability of ROS-J were confirmed. On the other hand, even though virtual forest environment in off-site reproduced by video and sound easily, it was clarified that the PRE could be expected to a considerable extent by the ROS-J.
