Although there is published information regarding the costs of participant recruitment for large-scale clinical trials, these findings may not be applicable for small feasibility studies. To determine the most effective recruitment strategy we adapted a metric developed by Chin Feman et al. (). We compared costs and enrollment rates associated with various recruitment strategies. We recruited persons with mild to moderate dementia for a feasibility study that sought to adapt laboratory measures of daytime function to the home. We recruited from 1) enrollees in a Memory Research Center, 2) Alzheimer’s disease support groups, 3) the Reynolds Senior Health Center Clinic at the University of Arkansas for Medical Sciences, and 4) senior citizens housing. We determined that recruitment through the Memory Research Center was most effective (enrollment rate 67%, salary costs $49.47 per participant). These findings have implications for investigators preparing budgets for studies involving populations with dementia.
