The Effects of a Combination of 3D Virtual Reality and Hands-on Horticultural Activities on Community-dwelling Older Adults’ Mental Health: A Quasi-Experimental Study (Preprint)
BACKGROUND Aging societies are of public health concern worldwide. It is critical to develop strategies that harness technology to enhance older adults’ mental health. OBJECTIVE This study aimed to explore the effects of a combination of 3D virtual reality (VR) and hands-on horticultural activities on the mental health of community-dwelling older adults. METHODS The study used a quasi-experimental design. A total of 62 community-dwelling older adults were recruited and assigned to the experimental (n=32) and comparison groups (n=30). The members of the experimental group participated in an 8-week intervention program. Participants of both groups completed before-and-after intervention measurements for outcome variables that included perceived self-esteem, depression, isolation, mastery and achievement motives, which were analyzed using the generalized estimating equation (GEE). RESULTS GEE analyses indicated that the experimental group showed significant post intervention improvements in scores for self-esteem (β=1.66, P= .015), isolation (β=-0.96, P= .008), mastery (β=1.04, P= .042), and achievement motives (β=1.30, P=.034) compared to the control group. CONCLUSIONS This study found beneficial effects of a combination of three-dimensional virtual reality and hands-on horticultural activities on community-dwelling older adults’ mental health. These findings suggest that future implementations of this program on a large scale could improve the mental health of older adults. CLINICALTRIAL The study was approved from the Research Ethics Review Committee of En Chu Kong Hospital (Registration number: ECKIRB1090503).
