Telephone-delivered Walk With Ease program recruitment strategies compared in adults with arthritis
This randomized trial (n=267) evaluated recruitment strategies for a 6-week telephone-delivered Walk With Ease program in adults with arthritis. The population was primarily female (92%) and Black (60%), with an average age of 64.1 ± 9.4 years and average BMI of 34.2 ± 7.7 kg/m². The primary outcome was enrollment yield per recruitment strategy.
The most successful strategies were Facebook (32%), radio advertisements (24%), word of mouth (13%), and community events or organizations (10%). For Black participants, radio advertisements were the top strategy (39%); for lower-income participants, radio advertisements were also top (28%). Facebook was most effective among non-Black and higher-income participants. No difference in recruitment strategies was found by age group (<65 years vs ≥65 years).
Safety and tolerability were not reported. Key limitations include that recruitment strategies were not randomly assigned, making enrollment yields observational comparisons; the study focused on recruitment, not intervention outcomes; and the sample was primarily female and Black, which may limit generalizability. Practice relevance is that public health practitioners can tailor recruitment strategies based on priority population, using Facebook for general effectiveness and radio advertisements for Black and lower-income participants.
