Did we call you for a telephone interview?
People age 45 to 85 years are randomly selected to receive an information package or a telephone call inviting them to participate in the study.
Once you've given your consent for us to contact you, we will be calling to answer any additional questions you may have and to find out if you want to participate in the study.
If you chose to take part, we'll then book a convenient time for our first in-depth telephone interview. We will need a copy of your signed consent form to include you in the study.
Here's what participation involves:
- A CLSA interviewer will contact you by telephone at your convenience, to ask questions about your physical, emotional and social health functioning. This interview will be repeated every three years and it will last between 60 to 70 minutes.
- A CLSA interviewer will call you mid-way between each three-year interview to maintain contact and ask you a few more questions about your health and well-being. This call will last approximately 35 minutes.
You will also be given the following option:
- Provide the CLSA with your provincial health card number to 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).
Remember, you may still participate in the study even if you decline to provide your provincial health card number and your healthcare will be in no way affected by this decision.
The study information package is available here.
