A Systematic Review of the Effects of Horticultural Therapy on Persons with Mental Health Conditions
Summary
This systematic review delves into the impact of horticultural therapy (HT) on individuals grappling with mental health conditions. Researchers rigorously analyzed 14 studies published between 1992 and 2015, employing the McMaster’s Critical Review Form to meticulously evaluate the quality and relevance of each study. The HT interventions encompassed a variety of activities, including gardening, planting, and engaging in other plant-related tasks.
The review revealed moderate evidence suggesting that HT can lead to improvements in client factors and performance skills among individuals with mental health conditions. Notably, 11 of the 14 studies showcased statistically significant improvements in at least one measured outcome after participants engaged in HT. These positive outcomes spanned diverse settings and mental health conditions, indicating the potential of HT as a valuable therapeutic approach. The study highlights the need for more research using randomized control trials to strengthen the evidence for HT.
