Getting Older adults OUTdoors (GO-OUT)

Research assistant/data analyst, Under the supervision of Dr. Ruth Barclay, College of Rehabilitaion Sciences, University of Manitoba, 2021

Purposes

The purposes of this project are using the data from the GOOUT to: a) develop a model adapted from the conceptual framework of the GOOUT intervention (Salbach et al. (2019)), b) explore the complex relationship among individual characteristics and environmental characteristics and outdoor walking in older adults with outdoor walking difficulties.

Canadian Longitudinal Study on Aging (CLSA)

Research assistant, Under the supervision of Dr. Ruth Barclay and Dr. Sandra Webber, College of Rehabilitaion Sciences, University of Manitoba, 2020

Purposes

The purposes of this project are using the data from the CLSA to: 1) validate a model for community ambulation that was developed for stroke patients (Barclay et al. (2014)), 2) develop a model for mobility based on a conceptual framework (Webber et al. (2010)) for people aged 65+ and people with arthritis on knees or hips, respectively. In addition, measurement invariance was tested for age and sex.
