Study Description

Brief Summary

Dementia is widely prevalent and results in high direct and indirect health costs. Dementia is associated with stress, anxiety, and depression in both patients and caregivers, and caregiver burden is extremely common. Treatment protocols for patients and caregivers are unclear and insufficient; drug treatments to manage behavioural and psychological symptoms of dementia can yield serious negative side effects, and caregivers may not have access to one-on-one psychotherapy due to high costs and long wait times. Yoga is an ancient Indian mind-body practice that uses physical postures, breathing exercises, and meditation. Yoga may be a viable therapeutic modality to address the psychological challenges associated with dementia in patients and caregivers, as it has been shown to decrease stress and improve anxiety and depressive symptoms in various populations. Recent research has suggested that patients with dementia and their caregivers may also experience positive effects on their mental health from practicing yoga. Furthermore, when yoga is taught in a gentle and mindful manner, it is generally not associated with any negative side effects. While there is preliminary data on dyadic exercise interventions for dementia patients and their caregivers, to date no research has examined the effectiveness of a dyadic yoga intervention on stress, anxiety, and depression.

The investigators propose an 8-week study of a dyadic chair yoga program for patients with mild to moderate dementia and their caregivers (n = 30-40 participants). Our primary outcome of interest is changes in perceived stress, while secondary outcomes include changes in symptoms of depression and anxiety. The investigators will also look at the effects of the chair yoga program on caregiver burden, quality of interactions, well-being, mindfulness, and self-compassion. All outcomes will be assessed before the program starts and upon its termination. Participants will attend a 1-hour weekly group yoga class (4-10 participants per group) with their dyad for 8-weeks, and will also be given a video recording of a yoga class to practice together at home as often as possible. The investigators hypothesize that after the 8 week yoga program, patients and caregivers will report lower stress, as well as reduced symptoms of anxiety and depression. Results will be available mid-2020.

Outcome Measures

Primary Outcome Measures

Changes in perceived stress scores as measured by the Perceived Stress Scale (PSS) [Baseline, 8-weeks]
Using an 8-week single arm pilot trial, assess the effects of chair yoga on perceived stress in patients and caregivers, using the PSS. Scores on the PSS can range from 0-40, with higher scores indicating higher perceived stress Hypothesis: Following participation in an 8-week gentle chair yoga program, patients with dementia and their caregivers will report lower perceived stress, as measured by the Perceived Stress Scale (PSS)

Secondary Outcome Measures

Changes in depressive symptoms as measured by the Patient Health Questionnaire (PHQ-9) [Baseline, 8-weeks]
Using an 8-week single arm pilot trial, assess the effects of chair yoga on patient and caregiver depressive symptoms using the PHQ-9. Scores on the PHQ-9 can range from 0-27, with higher scores indicating more severe depression. Hypothesis: Patients with dementia and their caregivers will report less severe symptoms of depression, as measured by the full version of the Patient Health Questionnaire (PHQ-9), following participation in an 8-week gentle chair yoga program.
Changes in symptoms of anxiety as measured by the Generalized Anxiety Disorder 7-item scale (GAD-7) [Baseline, 8-weeks]
Using an 8-week single arm pilot trial, assess the effects of chair yoga on symptoms of anxiety in patients and caregivers using the GAD-7. Scores on the GAD-7 range from 0-21, with higher scores indicating more severe anxiety. Hypothesis: Patients with dementia and/or their caregivers will report fewer symptoms of anxiety, as measured by the Generalized Anxiety Disorder 7-Item Scale (GAD-7), following participation in an 8-week gentle chair yoga program.

Other Outcome Measures

Changes in caregiver burden as measured by the Zarit Burden Inventory (ZBI) [Baseline, 8-weeks]
Assess the effects of chair yoga on caregiver burden using the ZBI following 8 weeks of chair yoga. Scores on the ZBI can range from 0-88, with higher scores corresponding to higher levels of burden. Hypothesis 1: Caregivers of patients with dementia will report lower caregiver burden, as measured by the Zarit Burden Scale (ZBI), following participation in an 8-week gentle chair yoga program. Hypothesis 2: Lower patient scores on the PHQ-9 and GAD-7 (week 8) will be associated with decreased caregiver burden following participation in an 8-week gentle chair yoga program.
Changes in relationship closeness as measured by the Whitlatch Relationship Closeness Scale [Baseline, 8-weeks]
Assess the effects of chair yoga on levels of caregiver-rated relationship closeness using the Whitlatch Relationship Closeness Scale. Scores on the Whitlatch Relationship Closeness Scale range from 0-24, with higher scores indicating closer relationships.
Changes in well-being as measured by the 12-Item Well-Being Questionnaire (W-BQ12) [Baseline, 8-weeks]
Assess the effects of 8-weeks of chair yoga on patient and caregiver well-being using the W-BQ12. Scores on the W-BQ12 range from 0-72, with higher scores indicating a greater sense of well-being.
Changes in levels of mindfulness as measured by the Five Facet Mindfulness Questionnaire (FFMQ-short form) [Baseline, 8-weeks]
Assess the effects of 8 weeks of chair yoga on patient and caregiver levels of mindfulness using the short form of the FFMQ. Scores on the short-form of the Five Facet Mindfulness Scale range from 0-120, with higher scores indicating higher levels of mindfulness.
Changes in levels of self-compassion as measured by the Self-Compassion Scale (SCS-short form) [Baseline, 8-weeks]
Assess the effects of 8 weeks of chair yoga on patient and caregiver levels of self-compassion using the short form of the SCS. Scores on the short for of the SCS range from 0-60, with higher scores indicating higher levels of self-compassion.
