Objective: We conducted a cluster-randomized trial evaluating an intervention that trained Chinese-American primary care physicians to increase their Chinese patients’ colorectal cancer (CRC) screening. Methods: Twenty-five physicians (13 randomized to the intervention arm and 12 to the control arm) and 479 of their patients (aged 50-75 and nonadherent to CRC screening guidelines) were enrolled. The intervention, guided by Social Cognitive Theory, included a communication guide and 2 in-office training sessions to enhance physicians’ efficacy in communicating CRC screening with patients. Patients’ CRC screening rates (trial outcome) and rating of physician communication before intervention and at 12-month follow-up were assessed. Intention-to-treat analysis for outcome evaluation was conducted. Results: Screening rates were slightly higher in the intervention vs. the control arm (24.4% vs. 17.7%, p = .24). In post hoc analyses, intervention arm patients who perceived better communication were more likely to be screened than those who did not (OR = 1.09, 95% CI: 1.03, 1.15). This relationship was not seen in the control arm. Conclusions: This physician-focused intervention had small, non-significant effects in increasing Chinese patients’ CRC screening rates. Physician communication appeared to explain intervention efficacy. More intensive interventions are needed to enhance Chinese patients’ CRC screening.
