 This study evaluates the cost-effectiveness, time-effectiveness, and sociodemographic representation of diverse recruitment methods used to enroll participants in the Interact Study, a cohort study conducted in Canadian cities. The study found that Facebook advertisements generated the most recruits at a cost of five Canadian dollars and four cents, US 1.57, per completer, while mailed letters were the costliest but served to reach older participants. All methods resulted in a gender imbalance, with women participating more. A generalized linear model for daily Montreal recruitment identified two-day lag effects on most recruitment methods, except for the snowball campaign, four days, letters, 15 days, and reminder cards, five days. The study highlights the need for more comprehensive documentation and reporting of recruitment efforts across studies to improve our capacity to conduct inclusive intervention research.
