In November 2001, the Institute of Aging of the Canadian Institutes of Health Research (CIHR) issued a Request for Applications (RFA) for the development of a protocol for a new initiative, the Canadian Longitudinal Study on Aging.
The RFA was officially launched at a planning workshop held in November 2001 in Aylmer, Québec. As a result of that workshop, a research team headed by three principal investigators – Dr. Susan Kirkland, Dalhousie University; Dr. Parminder Raina, McMaster University, and Dr. Christina Wolfson, McGill University – submitted a joint application, and were awarded CIHR funding to undertake this initiative over an 18-month period, beginning in October 2002.
The protocol was developed and submitted for international review in January 2004. A feasibility phase was funded by CIHR to March 31, 2006. The content validity phase protocol was submitted for international review in May 2006. The CLSA recruitment pilot study commenced in October 2008.
In collaboration with Statistics Canada, the CLSA launched the recruitment of the first 20,000 participants for the telephone-interview portion of the study in 2009. In March 2010, four Computer-Assisted Telephone Interview (CATI) sites became fully operational at the University of Victoria, the University of Manitoba, the University of Sherbrooke and Dalhousie University.
In 2010, the CLSA embarked on a coordinated ethics review process with 11 ethics boards from across Canada. Conditional approval of the CLSA protocol was received in December 2010. Final approval was granted in June 2011.
A pilot study to assess the feasibility of the in-home interview was held in Montreal and Hamilton in spring 2011. In December 2011, the CLSA welcomed its first group of participants for a pilot study at the Data Collection Site (DCS) at McMaster University. An additional pilot took place in Montreal in early 2012. The study was conducted with French-speaking participants at the Research Institute of the McGill University Health Centre.
In 2011, the CLSA launched its next cycle of recruitment for the telephone-interview portion of the study in partnership with provincial ministries of health.
Recruitment of the 30,000 participants, who will take part in the at-home interviews and Data Collection Site visits, began in early 2012.
