Study Overview

The goal of the study was to compare the efficacy of two interventions to increase colorectal cancer (CRC) screening among Chinese Americans aged 50 to 75 years who spoke English, Cantonese, or Mandarin in San Francisco, CA.


A cluster randomized comparative trial was conducted from 2010 to 2014 to test a lay health worker (LHW) intervention plus in-language brochure (LHW+print) versus brochure (print). LHWs in the LHW+print arm were trained to teach participants about CRC in two small group sessions and two telephone calls.  The primary outcome was change in self-reported ever receipt of CRC screening and being up to date for CRC screening from baseline to 6 months post intervention.
