Models illustrating perceived susceptibility as an indirect effect of the change in a psychosocial variable on colorectal cancer screening (CRCS) intention or behavior (path 1* path 2) and as a moderator of change in a psychosocial variable (path 3) while accounting for the direct effect (path 4) and potential covariates. Models were repeated for each psychosocial (perceived benefits, barriers, self-efficacy, and family influence) and outcome variable.
Legend: BL = baseline, Y1 = Year 1, Y2 = Year 2, CRC = colorectal cancer, CRCS = CRC screening
