title: [Psychological Effects of Forest Therapy Program on Workers].
abstract: OBJECTIVE
  To examine the psychological effects of forest therapy program on workers.
  
  
  METHODS
  The subjective symptoms index, a shortened version of the profile of mood states (POMS), and a semantic differential (SD) method were used to measure the psychological effects.
  
  
  RESULTS
  The evaluations were performed 3 days before, during, and 1, 3, and 5 days after the forest therapy. The following results were obtained: (1) the subjective symptoms improved before breakfast and continued for 5 days; (2) the mood evaluated using POMS improved before breakfast and continued for 3 days; and (3) “comfortable,” “relaxed,” and “natural” feelings evaluated using the SD method were enhanced before breakfast, lunch, and dinner during forest therapy.
  
  
  CONCLUSIONS
  These results provided scientific evidence of the psychological effects of forest therapy program on workers.
