Abstract

This study was conducted in order to examine the effects of horticultural therapy on stress in demented elders, and for this purpose, we analyzed stress-related physiological changes in demented elders under the care of an elderly facility who had not taken medication and consented to blood tests. The horticultural therapy program included only flower decoration, which was preferred by the participants, aiming ultimately to reduce stress. First, a one-to-one session was given for forming rapport and the horticultural therapist had many conversations about plants with the elders. Furthermore, the participants were induced to be absorbed into the horticultural activities, though a short while, so that they might forget troubles. Evaluation was made by measuring subjective stress and the blood cortisol hormone concentration before and after the horticultural therapy and examining differences between them. Subjective stress increased from 12.88 to 17.88 in the control group, but decreased significantly from 13.88 before the therapy to 6.38 after in the experimental group (p = 0.007). When the blood cortisol hormone level was measured as a physiological indicator of stress, it decreased significantly from $11.33{\mu}g{\cdot}L^{-1}$ before the horticultural therapy to $9.85{\mu}g{\cdot}L^{-1}$ after (p = 0.037). These results suggest that horticultural therapy reduces the blood cortisol hormone level and is effective in easing stress.

본 연구는 원예치료가 치매노인의 스트레스와 혈중 코티졸에 미치는 영향에 대해서 알아보기 위하여 노인시설에서 보호를 받고 있는 치매노인 중에서 약물을 복용하지 않으며 혈액검사에 동의한 자를 대상으로 하였다. 원예치료 프로그램은 치매노인의 스트레스 감소를 궁극적 목표로 대상자들이 선호하는 꽃 장식만을 실시한 결과 주관적 스트레스 측정결과 대조군은 12.88점에서 17.88점으로 스트레스 수치가 높아진 반면에 실험군은 원예치료 실시 전 13.88점에서 실시 후 6.38점으로 유의하게(p = 0.007) 낮아졌다. 스트레스의 생리적인 변화로 혈중 코티졸 호르몬을 측정한 결과 원예치료 실시 전 $11.33{\mu}g{\cdot}L^{-1}$에서 실시 후에 $9.85{\mu}g{\cdot}L^{-1}$로 혈중 코티졸 호르몬의 수치가 유의하게(p = 0.037) 낮아지는 것을 볼 수 있었다. 이와 같이 원예치료는 혈중 코티졸 호르몬 수치를 낮추어 주어 스트레스 감소에 효과적인 것을 알 수 있었다.
