Did you take part in a telephone interview only?

Participants who take part in extensive telephone interviews are in the study’s ‘tracking’ assessment. This group includes individuals from all 10 provinces, who the CLSA will follow for 20 years. 

Watch this video to find out more about the telephone interviews.

Here is what participation involves:

  • As you have consented to take part in this study for 20 years, you will be contacted again by a CLSA interviewer to schedule a time at your convenience, to answer questions that are mostly the same as during your previous interview.
  • There are a few additional questions in each follow-up, to ensure we are gathering the most comprehensive data about your physical, medical and emotional health, as well as the social, lifestyle and economic aspects of your life.
  • You may also be asked to provide the CLSA with a Proxy Consent form to allow someone other than yourself to answer questions about your health if you are no longer able to take part in the interview on your own at this time, or in the future.
  • If you previously agreed to share your provincial health insurance number with the CLSA, but have not yet done so, we will be asking for it. Health insurance numbers allow researchers to link the information you provide to health care or other databases held by public institutions (for example, each provincial Ministry of Health keeps databases about your visits to doctors, hospital admissions, medication prescriptions or mortality records). Your decision to provide a health card number is voluntary, and will not affect your participation in the study.
