Mindfulness-based Cognitive Therapy (MBCT) for People With Parkinson's Disease

Study Overview
=================
Brief Summary
-----------------
This study aims to explore the feasibility and effectiveness of mindfulness-based cognitive therapy (MBCT) in reducing anxiety and/or depressive symptoms in people with Parkinson's disease.

Detailed Description
-----------------
An adapted MBCT intervention will be offered to people with Parkinson's disease and mild-to-moderate depression and/or anxiety. Two 8-week long MBCT groups will be held between September 2019 and March 2020, based on the adapted protocol. Modifications will include shortening the traditional 120-minute to 90-minute format and performing mindful yoga from a chair, instead of a floor mat. Participants will be recruited from the community, according to the eligibility criteria detailed below. The participants' pre- and post-MBCT anxiety and/or depressive symptom severity and mindfulness levels (as measured with standardized, validated scales) will be compared, using a paired t-test.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in anxiety symptom severity | Change in Generalized Anxiety Disorder-7 item score (for participants with anxiety). The scale score range is 0-21, with higher scores indicating more severe anxiety. | From pre- to post-MBCT 8 weeks later | 
| Change in depressive symptom severity | Change in Patient Health Questionnaire-9 score (for participants with depression). The scale score range is 0-27, with higher scores indicating more severe depression. | From pre- to post-MBCT 8 weeks later | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in mindfulness levels | Change in 15 item-Five Facet Mindfulness Questionnaire score. The scale score range is 0-75, with higher scores indicating higher mindfulness levels. | From pre- to post-MBCT 8 weeks later | 
| Time spent practicing mindfulness | Number of minutes per week spent practicing mindfulness exercises | During MBCT group (8 week-period) |
