At the 24-week point, the waitlist control participants will be invited to receive the intervention. This combines a between groups RCT design with a phase change/within-group design for maximum efficiency with a limited N. Randomization will occur at the level of the individual participant. To sustain participant interest and to address obesity-related needs, control arm participants will receive Best Practices services including 1) Individual counseling about pre-diabetes risk at baseline; 2) mailed written materials at weeks 6, 12, 18; and 3) As needed additional FQHC Primary Care services (as mentioned, referral to the DPP obesity intervention and FHCN/FQHC primary care services will be bidirectional. The RE-AIM framework will guide process and impact evaluation measures of this intervention.
