Women's preferences for selective estrogen reuptake modulators: an investigation using protection motivation theory.

Abstract

OBJECTIVE: Selective estrogen receptor modulators (SERMs) reduce breast cancer risk by 38%. However, uptake is low and the reasons are not well understood. This study applied protection motivation theory (PMT) to determine factors associated with intention to take SERMs. METHODS: Women at increased risk of breast cancer (N=107), recruited from two familial cancer clinics in Australia, completed a questionnaire containing measures of PMT constructs. Hierarchical multiple linear regression analysis was used to analyze the data. RESULTS: Forty-five percent of women said they would be likely or very likely to take SERMs in the future. PMT components accounted for 40% of variance in intention to take SERMs. Perceived vulnerability, severity and response efficacy appeared the most influential in women's decisions to take or not take SERMs. CONCLUSION: Many women are interested in SERMs as a risk management option. Accurate risk estimation and an understanding of the benefits of SERMs are critical to women's decision making. PRACTICE IMPLICATIONS: Health professionals need to explore women's perceptions of their risk and its consequences, as well as providing clear evidence-based information about the efficacy of SERMs. Exploring the source and strength of beliefs about SERMs may allow more effective, tailored counseling.
