How information about overdetection changes breast cancer screening decisions: a mediation analysis within a randomised controlled trial.

ABSTRACT:

Objectives

In a randomised controlled trial, we found that informing women about overdetection changed their breast screening decisions. We now present a mediation analysis exploring the psychological pathways through which study participants who received the intervention processed information about overdetection and how this influenced their decision-making. We examined a series of potential mediators in the causal chain between exposure to overdetection information and women's subsequently reported breast screening intentions.

Design

Serial multiple mediation analysis within a randomised controlled trial.

Setting

New South Wales, Australia.

Participants

811 women aged 48-50 years with no personal history of breast cancer.
