Optimism, Worry, and Colorectal Cancer Screening among Low-income Latinos

Objective: In this paper, we examine the relationship of optimism and screening colonoscopy (SC) completion among low-income Latinos at average colorectal cancer risk. Methods: Partici- pants were 305 Latinos referred for SC with a patient navigator. We assessed optimism (LOT- R), cancer worry, and other health-related characteristics at baseline and at 3 months. Results: Lower optimism (optimism OR = 0.89; 95% CI = [0.81, 0.98]) and higher cancer worry (worry OR = 1.87; 95% CI = [1.17, 2.99]) were associated with SC completion. Language preference, self- reported health, nativity, and proactive and adherent health behaviors were associated with optimism. Optimism was inversely associated with cancer worry and colonoscopy fear. Conclusion: Latinos with lower optimism and higher cancer worry are more likely to complete SC.
