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.
