Abstract
Objective: Relatives of colorectal cancer (CRC) patients are at increased risk for the disease, yet screening rates still remain low. Guided by the Extended Parallel Process Model (EPPM) we examined the impact of a personalized, remote risk communication intervention on behavioral intention and colonoscopy-uptake in relatives of CRC patients, assessing the original additive model and an alternative model in which each theoretical construct contributes uniquely. Methods: We collected intention-to-screen and medical-record-verified colonoscopy information on 218 individuals who received the personalized intervention. Results: Structural equation modeling showed poor main model fit (RMSEA=0.109; SRMR=0.134; CFI=0.797; AIC=11601; BIC=11884). However, the alternative model (RMSEA=0.070; SRMR=0.105; CFI=0.918; AIC=11186; BIC=11498) showed good fit. Cancer susceptibility (B =0.319, p
