Abstract
Recruiting and retaining clients in health interventions can be challenging especially when targeting multiple behavior change in high-risk populations. To inform the methods of trials working with similarly complex clinical populations, we describe multi-pronged efforts to recruit and retain a representative sample. In a two-group RCT, veterans were recruited from a Veteran Affairs Medical Center. The goal was to enroll 200 participants over a 25-month period, and to exceed 70 % follow-up for all treatment arms. To meet these goals, a four-pronged strategy was developed: branding, outreach/networking, onsite presence, and incentives. In month 1, 32 % of the proposed sample size was met (n = 64), and by month 2, 45 % (n = 90); the recruitment goal (n = 200) was achieved 13 months ahead of schedule. Retention exceeds 90 % at all time points out to 18 months. The multipronged recruitment and retention plan was efficient, cost effective, and may generalize to other health promotion initiatives.

Implications
Practice: Individuals with addiction problems often have additional risk behaviors in need of treatment but can be challenging to engage, so practitioners need to consider multiple strategies for outreach and ongoing engagement in health interventions.
Research: For maximizing external validity of research findings, researchers ought to utilize a multi-pronged approach for efficient recruitment and strong retention.
Policy: Investments in treatment programs need to consider planning and resources for outreach and ongoing engagement.
