Population and recruitment Twenty-three community organizations in Greater Montreal agreed to collaborate on a multi-site study and each recruit 15 seniors. For inclusion in the main study, the participants had to meet several criteria: 1) to be aged 60 or over; 2) speak French; 3) agree to participate in a study over a period of one year; 4) to be interested in participating in a workshop promoting cognitive vitality, involving one 2-hour meeting per week over 10 weeks; 5) could not have followed a similar program in the year prior to their participation in this study; 6) could not have received a diagnosis for cognitive impairment. The organizations had a selection chart to help them recruit subjects. This program was publicized through their regular communication channels such as; seniors’ activity calendars; ads in local newspapers and presentations. Thirteen groups offered the program the first year (experimental groups), and ten agreed to wait a year before offering the program (control groups).
