This study aimed to investigate the effects of participating in forest-themed do-it-yourself (DIY)
activities on mood states. Three types of forest-themed DIY activities were examined: Essential
oils, Seed pendant, and Wood burning. The Profile of Mood States (POMS) scale was used to
assess seven mood dimensions: “confusion,” “vitality,” “fatigue,” “anger,” “self-esteem,” “anxiety,”
and “despair.” Paired-sample t-tests were conducted to determine whether there were significant
changes in participants’ moods before and after each activity. The results indicated that participants
in the Essential oils activity showed significant differences in six of the seven mood dimensions,
with “despair” being the only exception. Participants in the Seed pendant activity demonstrated
significant changes in four dimensions, with no significant differences observed in “anger,” “selfesteem,”
and “despair.” By contrast, participants in the Wood burning activity exhibited significant
changes across all seven mood dimensions. These findings suggest that engaging in forest-themed
DIY activities could enhance positive mood states and reduce negative mood states.
