A message to CLSA participants about COVID-19

The Canadian Longitudinal Study on Aging (CLSA) is dedicated to supporting and improving the health and quality of life for all people living in Canada through conducting high-quality research.

In the past month we have all been challenged by the disruption and risks the coronavirus, or COVID-19, has introduced into our lives. From physical distancing and social isolation to job uncertainty and travel restrictions, we have seen unprecedented change. At the CLSA, this has also meant adapting how we do research to act in the best interests of our participants and staff.

On March 16th, the CLSA suspended face-to-face data collection with participants. In the meantime, we are continuing to collect questionnaire-based information from participants through telephone interviews.

Over the next few weeks, we will be contacting you to invite you to complete a series of online or telephone interviews that include questions about your experiences related to the COVID-19 pandemic. If you choose to take part, these interviews will be in addition to your regular CLSA participation.

We hope you will consider participating in the COVID-19 interviews and work hand-in-hand with the CLSA to make an important contribution to understanding the impact of a pandemic on the health and wellness of the Canadian population. As always, your participation is entirely voluntary.

I want to thank you again for your ongoing contributions to the CLSA.

Please take care of yourself and others around you.

March 12, 2020

To protect the health and safety of Canadian Longitudinal Study on Aging (CLSA) participants and staff and to help reduce contacts that might spread the coronavirus, the CLSA has made the difficult decision to suspend face-to-face data collection with participants for a period of two weeks.

The suspension takes effect Monday, March 16, 2020.

Participants will be asked to complete interviews by phone.

Following the two-week period, the CLSA will reassess the situation and determine when in-person data collection can resume.

Who should I contact if I have questions?
