“…Multi-site RCTs (Campbell et al, 2007; Watson & Torgerson, 2006), studies that include minority participants (Fouad et al, 2004; Greenwald & Davis, 2000; Haskins & Kirk-Sanchez, 2006; Hodge, Weinmann, & Roubideaux, 2000; Horowitz, Brenner, Lachapelle, Amara, & Arniella, 2009; Mhurchu et al, 2009; Paskett et al, 2008), studies requiring active parental consent for child participation (Esbensen, Melde, Taylor, & Peterson, 2008; Johnson et al, 1999; McCormick et al, 1999), and studies in rural communities (Wages, Jackson, Bradshaw, Chang, & Estabrooks, 2010) all pose unique recruitment and retention challenges. These challenges can be magnified in trans-community RCTs which require substantial community engagement, relationship building, and focused effort at multiple levels (US Department of Health and Human Services, 2011).…”
