This investigation extends prior research to apply decision-making constructs from the transtheoretical model (TTM) of behavior change to mammography screening. Study subjects were 8,914 women ages 50-80, recruited from 40 primarily rural communities in Washington State. Structural equation modeling showed that favorable and unfavorable opinions about mammography (i.e., pros and cons) fit the observed data. Analysis of variance supported the associations between readiness to obtain screening (i.e., stage of adoption) and opinions about mammography (i.e., decisional balance) previously found in research using smaller samples from another geographic region. This report extends these earlier studies by using structural equation modeling, opinion scales based both on principal component analyses and on a priori definitions, a developmental sample and a confirmatory sample, and by sampling from a different geographic region. It is recommended that future research examine whether opinions regarding the cons of mammography are more individually specific than the pros.
