Timeline of engagement with residents. Group A (n = 25) received the garden intervention first (May 2017), with Group B (n = 17) acting as a Control. Group B received their own garden intervention in May 2018, allowing for a pre- and post- evaluation of this group, as well as for Group A. (▲=garden intervention; ○=cortisol samples; ■=questionnaires and ♦=interviews). Data was pooled for pre- and post-questionnaires due to not all residents completing questionnaires on each occasion. Where an individual resident repeated the questionnaire, e.g. after the intervention, then mean scores were used in the subsequent analyses.
