Measuring nature-based health interventions – a rapid review of instrumentation and outcomes

Abstract

AbstractNature-based health interventions (NBHIs) are utilised to treat a range of physical and mental health conditions, and this rapid review sought to describe the breadth of instrumentation utilised to measure the effectiveness of NBHIs on the different domains of health and wellbeing. A total of 14,385 records were extracted from three databases, and a review of titles and abstracts and then of full text resulted in a final dataset of 167 articles that met the review criteria. NBHI settings were categorised as Garden/Horticulture, Blue Spaces, Urban Green Spaces, Wild Nature, and Camps/Residential. For each of these settings, major population groups included in the studies, health domains and outcomes addressed, as well as assessment tools used to measure NBHIs’ effectiveness were described and analysed in aggregate. A total of 336 measurement tools were utilised across the dataset, with only 29 being specifically designed to assess NBHIs. Most studies investigated mental health domains and measured the effectiveness of NBHIs to improve psychological factors and physical, behavioural, and healthy eating outcomes. Future research should interrogate how nature-based tools and outcome measurements could be used most effectively in NBHI settings.
