Title: A haven of green space: learning from a pilot pre-post evaluation of a school-based social and therapeutic horticulture intervention with children (2018)

Link: https://doi.org/10.1186/s12889-018-5661-9

Summary: A study in North West England of school children, aged 9-15, with ‘behavioural, emotional and social difficulties’ examined the effect of monthly therapeutic horticulture sessions over 6 months. Whilst the school reported better mental well-being, within questionnaires the 36 children self-reported worsening well-being. These results perhaps reflect the children completing their feedback on the last day of school. Despite challenges with the study design, this study provides examples of data collection methods suitable for children.
