Improving Risk Communication through Tailored Testimonials

About

Two experiments examine the effects of tailored testimonials on people's knowledge, satisfaction, interest in shared decision-making, and behavioral intentions after reading a colorectal cancer screening decision aid.

Aims

Aim 1. Examine whether tailored testimonials can improve decision aid outcomes such as knowledge, satisfaction, interest in shared decision-making, and behavioral intentions.

Aim 2. Test mediators through which tailored testimonials have effects.

Participants

Study 1 includes 1600 participants (2x2 design, 400 per cell) between ages 49-55, have never been screened for colorectal cancer (CRC).

Study 2 recruits the same participant total with the same characteristics as Study 1, but does not recruit any individual who participated in Study 1.
