Aim: To summarize the evidence from randomized controlled trials (RCTs) on the effects of horticultural therapy (HT). Methods: Studies were eligible if they were RCTs. Studies included one treatment group in which HT was applied. We searched the following databases from 1990 up to August 20, 2013: MEDLINE via PubMed, CINAHL, Web of Science, Ichushi-Web, GHL, WPRIM, and PsycINFO. We also searched all Cochrane Database and Campbell Systematic Reviews up to September 20, 2013. Results: Four studies met all inclusion criteria. The language of all eligible publications was English and Korean. Target diseases and/or symptoms were dementia, severe mental illness such as schizophrenia, bipolar disorder, and major depression, frail elderly in nursing home, and hemiplegic patients after stroke. These studies showed significant effectiveness in one or more outcomes for mental health and behavior. However, our review especially detected omissions of the following descriptions: method used to generate randomization, concealment, blinding, and intention-to-treat analysis. In addition, the results of this study suggested that the RCTs conducted have been of relatively low quality. Conclusion: Although there was insufficient evidence in the studies of HT due to poor methodological and reporting quality and heterogeneity, HT may be an effective treatment for mental and behavioral disorders such as dementia, schizophrenia, depression, and terminal-care for cancer.
