Context: Hispanic adults experience disparities in rates of colorectal cancer (CRC) screening. This RE-AIM analysis encompassed a multilevel decision support and navigation intervention (DSNI) for CRC screening. Interim findings were previously presented; we now aim to share the final analysis, particularly for effectiveness and implementation. Objective: Apply RE-AIM framework to a completed randomized controlled trial of a CRC screening intervention for Hispanic adults Setting: Five primary care practices Patients or Other Participants: Potential participants included a sampling frame of 2,720 screening-eligible patients, ages 50-75, Hispanic ethnicity, without history of CRC and polyps. 400 participants were enrolled. Intervention/Instrument: Decision support and navigation by a bilingual Patient Assistant (PA) as compared to a standard mailed intervention (SI) Main and Secondary Outcome Measures: 1) Reach- Study participants as compared to sampling frame 2) Effectiveness- Screening adherence 3) Adoption- Number of practice participants to complete intervention, engagement of patient and stakeholder advisory committee (PASAC) 4) Implementation- Quantitative data pertaining to patient contacts and communication of screening plan to primary care practices, Qualitative data on PA and Telephone Interviewer (TI) experiences 5) Maintenance- Health system dissemination (Pending). Results: 1) Reach- Study participants differed from the sampling frame in that ages 50-59 were overrepresented. There were no differences in race, gender, or language. 2) Effectiveness- Screening adherence was significantly increased in the DSNI group (73%) as compared to the SI group (44%) (OR=3.48, CI: 2.29-4.29, p
