“…For administrative reasons, the use of direct mailing was not possible, though this was shown to be an effective recruitment approach in other studies. 1,22 Finally, the exact number of overweight children in the study area is undocumented and could only be estimated. In summary, the subjective need for treatment is low in most families with overweight children.…”

“…These recruitment methods often incorporate reaching out to youth through schools and community centers, which can be costly in terms of personnel and resources [24] and may yield low enrollment rates [18]. School-based recruitment often means working with district-level administration for extended periods of time to gain access to a finite number of students [13].…”

“…Additional complications arising from schoolbased recruitment include class schedules, holidays, and student absenteeism [13]. Paper-based recruitment, such as printing and posting fliers in health clinics, can be time-consuming to implement and maintain [24] and can yield low recruitment rates [5]. As with school-based recruitment, permission to advertise in clinics and community facilities can require navigation of complex administrative networks.…”

Engaging and retaining adolescents in research studies is challenging. Social media offers utility for expanding the sphere of research recruitment. This study examined and compared traditional and Facebook-based recruitment strategies on reach, enrollment, cost, and retention. Substance users aged 13-17 years were recruited through several methods, including social media, a study website, fliers, talks in schools, bus ads, and referrals. Study involvement included a one-time visit and semiannual follow-up surveys. 1265 individuals contacted study personnel; 629 were ineligible; 129 declined; and 200 participants enrolled. Facebook drew the greatest volume but had a high rate of ineligibles. Referrals were the most successful and cost-effective ($7 per enrolled participant); school talks were the least. Recruitment source was unrelated to retention success. Facebook may expand recruitment reach, but had greater financial costs and more ineligible contacts, resulting in fewer enrollees relative to traditional interpersonal recruitment methods. Referrals, though useful for study engagement, did not provide a differential benefit in terms of long-term retention.

“…Previous reports on pediatric obesity intervention trials have described the employment of various recruitment methods (2,5,(7)(8)(9). Generally, a distinction can be made between active recruitment methods (e.g., recruitment through pediatricians, targeted mailing), in which researchers identify and directly target potential participants, and passive recruitment methods (e.g., flyer and posters, newspaper advertisement), in which participants identify themselves as potential participants (10).…”

Objective-Evaluate enrollment numbers, randomization rates, costs, and cost-effectiveness of active versus passive recruitment methods for parent-child dyads into two pediatric obesity intervention trials.Methods-Recruitment methods were categorized into active (pediatrician referral and targeted mailings, with participants identified by researcher/health care provider) versus passive methods (newspaper, bus, internet, television, and earning statements; fairs/community centers/schools; and word of mouth; with participants self-identified). Numbers of enrolled and randomized families and costs/recruitment method were monitored throughout the 22-month recruitment period. Costs (in USD) per recruitment method included staff time, mileage, and targeted costs of each method.Results-A total of 940 families were referred or made contact, with 164 families randomized (child: 7.2±1.6 years, 2.27±0.61 standardized body mass index [zBMI], 86.6% obese, 61.7% female, 83.5% white; parent: 38.0±5.8 years, 32.9±8.4 BMI, 55.2% obese, 92.7% female, 89.6% white). Pediatrician referral, followed by targeted mailings, produced the largest number of enrolled and randomized families (both methods combined producing 87.2% of randomized families). Passive recruitment methods yielded better retention from enrollment to randomization (p <0.05), but produced few families (21 in total). Approximately $91 000 was spent on recruitment, with cost per randomized family at $554.77. Pediatrician referral was the most costeffective method, $145.95/randomized family, but yielded only 91 randomized families over 22-months of continuous recruitment.Conclusion-Pediatrician referral and targeted mailings, which are active recruitment methods, were the most successful strategies. However, recruitment demanded significant resources. Successful recruitment for pediatric trials should use several strategies.

Cost effectiveness of recruitment methods in an obesity prevention trial for young children

Abstract: Background-Recruitment of participants for clinical trials requires considerable effort and cost. There is no research on the cost-effectiveness of recruitment methods for an obesity prevention trial of young children.
