Nature on prescription

Who is involved?

Theme: Mental Health & Dementia
Status: Live


Feelings of stress, depression and anxiety are common amongst both men and women in the UK, with sources suggesting that 1 in 4 women and 1 in 10 men experience depression on a serious enough level to require treatment during their lifetime. Typically, recommended treatment may include exercising or medication, such as anti-depressants. However, the desired effect is not always achieved with these options and patients may not be able, or wish to undertake these treatments. Because of this a new treatment approach is needed to encompass all needs and desires.

One set of treatments that are potentially suitable for diverse groups are nature-based group activities, such as community gardening or conservation work. There is evidence to suggest that the undertaking nature-based activities can have a positive impact on the patient wellbeing.  As a result, numerous organisations including MIND and the Conservation Volunteers, are working with GPs, nurses or mental health workers to offer them as a form of ‘social prescription’ or community referral.

However, there are questions surrounding nature-based activities, due to variety, frequency and length of attendance. It is therefore unclear what activities, delivered in what ways, may have the most positive impact on patients. 

Project aims

This project aims to provide evidence for these gaps in knowledge, by designing a programme of nature-based group activities suitable for prescribing through primary care and other pathways, allowing for a better understanding what programmes have the best impact.

To achieve the aim researchers will work with relevant NHS staff, people with common mental health conditions and their families and organisers of current nature-based group activities, and use existing information from research literature.

From this, we will be able to better understand and analyse how and why different elements of a programme might help with depression, anxiety and stress related conditions. Additionally, we will be able to explore how this should be organised for future activities, and be able to test the acceptability and effectiveness of nature-based group treatment.

Project activity 

This project will use a structured approach to developing a complex intervention, to design a nature-based intervention for people with, or at risk of, common mental health conditions. In addition to the three core MRC phases of: (a) identifying existing evidence; (b) identifying or developing a theory and (c) modelling process and outcomes; four other phases will also to be incorporated: (d) problem identification and definition; (e) determining of recipients' and providers' needs; (f) examination of current practice and context and (g) intervention design.

Three interlinked and iterative activities will inform phases (a) to (f): (i) Evidence syntheses (addressing phases a, b, c, e and f.) (ii) Stakeholder consultation: Initial consultation meetings with three core stakeholder groups: people with common mental health conditions and their families, including those who have previously taken part in nature-based activities, people from primary care, and those involved in delivering nature based activities (phases b, c, d, f). iii) Formal focus groups with each of the stakeholder groups will allow better understanding of current practice, perceived impacts and the needs of those with mental health conditions, primary care practitioners, and those who deliver nature-based activities (phases c, e, f).

Anticipated outputs 

A key output of these interlinked activities will be the detailed logic model and programme theory for the proposed intervention. This will map the relationship between programme resources, intervention components, symptoms and outcomes; specifying underlying theory and assumptions for these pathways. We will hold final consultation workshop with all the stakeholder groups to present the proposed programme design and refine it in response to their input.

Finally, we will produce an intervention manual (phase g) showing approaches to activity design; a detailed logic model and programme theory showing how nature-based, group activities may benefit those with, or at risk of, common mental health conditions in differing contexts and through differing mechanisms; and a protocol for use in a future feasibility study.
