Longitudinal analysis of differential effects on agitation of a therapeutic wander garden for dementia patients based on ambulation ability

A growth model within the framework of hierarchical linear modeling was used to assess the impact of visiting a wander garden on monthly agitation levels of a group of elderly veterans diagnosed with dementia, with attention to their ambulatory ability. A sample of 34 veterans residing in a locked ward in a dementia unit was observed for a baseline period and for twelve months after a wander garden was opened in their facility. Findings suggest that visiting the wander garden helped lower agitation levels in the dementia patients and that there was a differential effect based on the patient’s ability to walk unassisted.
