PoLLeN is a social and therapeutic horticulture project which began at the Bromley by Bow Centre in early 2010 and is for adults with direct experience of mental distress. The central aim of the project is to improve the mental and physical wellbeing of individuals through engagement with the natural environment.

This evaluation builds upon the earlier PoLLeN evaluation [Clift and Bungay (2012)] and aims to assess the extent to which PoLLeN at the Bromley by Bow Centre during 2012-2013 is achieving beneficial health and wellbeing outcomes for participants.

A mixed methods approach was used employing structured validated health and wellbeing questionnaires (the short form of the Clinical Outcomes in Routine Evaluation questionnaire (CORE10) and the short form of WEMWBS), together with the collection of qualitative data through written feedback, semi-structured interviews and case studies.

Following participants over the course of the evaluation showed that reported levels of mental distress and wellbeing were generally stable, with perhaps a little improvement between baseline and first follow-up, but then deterioration between first and second follow-ups. Results indicate that PoLLeN helps participants to remain stable and also provides support if and when members of the group suffer a relapse in their condition, or are affected by significantly increased stresses in their daily lives.
