Sample
Individuals for the study were recruited from local support organizations and movement disorder clinics in a large western Canadian urban centre. People were invited to participate in the original study via distribution of flyers, information sessions, and through contacts with nurses, physicians, and support staff. All volunteers underwent initial screening with a neurologist administering the Montreal Cognitive Assessment, the Unified Parkinson’s Disease Rating Scale, and the Movement Disorder Society (MDS) clinical criteria. Participants were included in the study if they: (1) met the MDS clinical criteria for PD (Postuma et al., 2015), (2) were diagnosed with PD within the last 5 years, and (3) had the capacity to provide consent. People with active psychotic symptoms, dementia symptoms, or who were unable to speak English were not included in the study.
