Input: We included one single blind study (total n = 24). The overall risk of bias in the study was considered to be unclear although the randomisation was adequate. It compared a package of horticultural therapy which consisted of one hour per day of horticultural activity plus standard care with standard care alone over two weeks (10 consecutive days) with no long-term follow-up. Only two people were lost to follow-up in the study, both in the horticultural therapy group (1 RCT n = 24,RR 5.00 95% CI 0.27 to 94.34, very low quality evidence). There was no clear evidence of a difference in Personal Wellbeing Index (PWI-C) change scores between groups, however confidence intervals were wide (1 RCT n = 22, MD -0.90 95% CI -10.35 to 8.55, very low quality evidence). At the end of treatment, the Depression Anxiety Stress Scale (DASS21) change scores in horticultural therapy group were greater than that in the control group (1 RCT n = 22, MD -23.70 CI -35.37 to - 12.03, very low quality evidence). The only included study did not report on adverse effects of interventions. Based on the current very low quality data, there is insufficient evidence to draw any conclusions on benefits or harms of horticultural therapy for people with schizophrenia. This therapy remains unproven and more and larger randomised trials are needed to increase high quality evidence in this area.
Output:

This review focuses on the effects of horticultural therapy for people with schizophrenia. An electronic search for relevant randomised trials was run in January 2013. Only one trial was included, it randomised a total of 24 people with schizophrenia to received either their standard care plus horticultural therapy or standard care only. The trial only lasted 2 weeks (10 consecutive days) with no long-term follow-up. There are few results and the quality of evidence was rated by the review authors to be very low quality. Some of the information from this one study favoured horticultural therapy but there is insufficient evidence to draw any conclusions on benefits or harms of horticultural therapy for people with schizophrenia. More large, better conducted and reported trials are required to determine the effectiveness and benefits of horticultural therapy.
