Using Normalization Process Theory to Evaluate the Implementation of Montessori-based Volunteer Visits Within a Canadian Long-term Care Home.

Background and Objectives
Montessori-based interventions (MBIs) have potential to improve the life quality of long-term care residents with dementia. In this study, we aimed to understand the processes by which staff integrated a volunteer-led MBI into practice within a special dementia care unit, and to explore staff members ' perceptions of associated strengths and limitations.


Research Design and Methods
This study relied on a qualitative descriptive design. Following a 3-month period of volunteer involvement, we conducted 21 interviews with staff members to document perceptions of the new program and subjected interview transcripts to qualitative content analysis, guided by normalization process theory.


Results
During the implementation of the volunteer-led MBI, staff members developed a shared understanding of the intervention, a sense of commitment, practical ways to support the intervention, and opinions about the value of the residents. Overall, we found that the volunteer-led MBI was quickly and successfully integrated into practice and was perceived to support both residents and staff members in meaningful ways. Nevertheless, some limitations were also identified.


Discussion and Implications
Volunteer-delivered MBIs are a useful adjunct to practice within a special dementia care unit. This article raises attention to some strengths and limitations associated with this approach.
