Brief Summary

The overall goals of our project is to understand the effects of participating in park visits and nature-based activities for people living with dementia and their caregivers. Nature-based activities such as park visits can have beneficial effects on quality of life, psychological symptoms and physical health. However, there may be barriers for people with dementia and their caregivers that may prevent them from engaging in park visits. The Nature Connections park visit program will provide education sessions for 10 persons living with dementia and 10 caregivers highlighting the beneficial effects of park visits and address common barriers to participating in park visits. Following the education session participants will be provided with weekly telephone/internet support meetings for participants to share their experiences with park visits and to address any challenges individuals encountered when trying to complete their visits. The impact of park visits on quality of life, behaviours, and measures of stress for people with dementia and their caregivers will be assessed over 8 weeks. Following completion of the program participants will provide an evaluation of the program to understand their experience and satisfaction with the program. This project will provide new information about the effects of park visits as a practical strategy to improve the quality of life, psychological symptoms and measures of stress for both people with dementia and caregivers.

Detailed Description

Background & Rationale:

Cognitive impairment has been the main focus in treating and caring for people living with dementia (PLWD). More recently, non-cognitive symptoms associated with dementia are increasing and forcing families to seek non-pharmacological treatment approaches for dementia related symptoms. Previous studies has also shown the effect of aerobic exercises and other non-pharmacological interventions in providing a range of benefit such as physical, mental, and emotional benefit in people without dementia, however, there is limited evidence on the effect of nature-based activities on PLWD. Many PLWD are disconnected from the outdoors due to a significant amount of time spent indoors resulting in reduced knowledge about how nature-based activities can benefit the QoL of PLWD. The specific aim of this project is to evaluate the effect of parks visit, an example of nature-based activities on the neuropsychiatric symptoms, QoL, cognition, stress and burden of PLWD and their caregivers.

Objectives:

1) The objective of this project is to investigate the impact of a 8-week nature park visit program intervention on stress, quality of life and cognition in 10 pairs of PLWD and their caregivers; 2) Evaluate the impact of potential barriers on participation in activity and their influence on the QoL of PLWD.

Methods:

10 pairs of PLWD and their caregivers who live in the community will be recruited into the nature connections intervention program. This study will be an open-label pilot study using pre-post design. The nature connections intervention will include an 8-week park visit program after which PLWD and their caregivers will be assessed on factors including changes in cognitive function, changes in mood and behaviors, changes in QoL, and changes in stress levels. These factors will be assessed in participants at baseline, week 4 (mid-intervention) and week 8 (post-intervention) to appropriately evaluate the impact of the intervention. Screening measures including demographics, cognition, physical activity, and functional ability will be assessed and collected during the screening period to meet the inclusion criteria for the study. Behavior and mood symptoms will be assessed using the Neuropsychiatric Inventory-Questionnaire (NPI-Q while depressive symptoms will be assessed using the Cornell Scale for Depression in Dementia (CSDD). Cognition will be measured using the Repeatable Battery for Assessment of Neuropsychological Syndromes (RBANS). Changes in Quality of life will be assessed using the Dementia Quality of Life (DEMQOL) assessment. The activity log of park visits will be recorded from baseline until week 8. Caregiver specific outcomes, caregiver burden and caregiver well-being and support will be assessed at baseline, week 4 during intervention and week 8 post intervention. Caregiver burden will be assessed using the Zarit Burden Interview (ZBI) while caregiver well-being and support will be measured using the Carer Well-being and Support questionnaire. The intervention will also include weekly check-in meetings where participants can discuss their experience with the park visits with other participants.

Data Analysis:

The primary outcome for PLWD is change in neuropsychiatric symptoms as measured from baseline to week week 8 on the NPI-Q using paired t-tests. Secondary outcomes include measurement of depressive symptoms (CSDD), cognition (RBANS), quality of life, care giver stress and caregiver burden (ZBI) at weeks 4 and week 8 of the study. Two-sided p-values of <0.05 will be used as the threshold for statistical significance.

Study Groups

Nature Connections Group

Participants will be screened to confirm their eligibility to partake in the study. Participants who meet the study criteria will then be invited to participate in the nature connections intervention. At the start of the intervention, mid-intervention and post intervention, participants will be invited to participate in assessments of their behaviour and mood symptoms, cognition, quality of life, caregiver burden and stress levels using different measures and questionnaires at the University of Calgary. Participants will be provided with a visit passport to record a log of activities completed during the park visits.

Group Type: EXPERIMENTAL

Nature Connections Intervention

Intervention Type: OTHER

10 PLWD and their 10 caregivers will be examined for the effects of a park visit program on their behaviour and mood symptoms, cognition, and quality of life over the period of 8-weeks. If participants meet the study criteria, an initial education session on the health benefits of nature will be provided to the them. Participants will then be invited to participate in the park visit program which will have them visiting local parks or outdoors spaces with their caregivers. They will be encouraged to allocate approximately 120 minutes each week to outdoor park activities for 8 weeks. Participants will be provided with a visit passport to record a log of activities completed during the park visits. During the 8 weeks of intervention, participants will also participate in a weekly check-in meeting with other participants to discuss about their experiences with the park visits.
