Overview of our 8-week positive psychotherapy intervention. Astute readers will note that our intervention has been built around Martin Seligman's PERMA model \cite{seligman2011,Seligman_2018} and positive psychotherapy \cite{Rashid_2018}, which combines models of 'hedonic' and 'eudaimonic' wellbeing, supplemented by a focus on positive health behaviours, behavior change and connections to the natural environment.
