| Abstract | Research in the area of breast cancer treatment decision making has typically focused separately on two issues: 1) what patients know about breast cancer and 2) what surgical treatments they undergo. The current research seeks to examine the link between knowledge and treatment decision making. To this end, two instruments were developed. The first instrument was a measure of breast cancer knowledge and the second was a measure of treatment decision making ability that assessed decision quality and causal reasoning skills. Participants were 142 women (53 breast cancer patients, 89 nonpatients). Patients performed significantly better than non-patients on the knowledge instrument and each of 4 decision quality outcomes. Results from regression analyses showed multiple predictors of decision quality, including breast cancer knowledge, patient status, age, and various information use factor scores. Results from this research provide a clearer picture of what participants know about breast cancer, the quality of their decisions, the importance of information and how information use is related to the decisions that participants make. In the future, these instruments can be used to determine patients' readiness to make their own breast cancer treatment decisions. Additionally, the knowledge gained from this research can be used to design educational interventions that teach patients what they need to know to make informed treatment decisions. |
