Background

In Lithuania every year one third of breast cancer cases are diagnosed at the latest stages (National Cancer Institute of Lithuania, 2011). It is considered that it is related with the low women's participation at breast cancer prevention, including breast self-examination.

 

Method

The participants of the study were 536 Lithuanian women with no BC, aged 18-85 (mean 45.48 SD±12.881). The questionnaire of the study consisted of demographic, risk (Gail, 1989), knowledge of risk factors and epidemiology of BC (Stager, 1993) assessment questions and the scales of components of social cognitive behavioural change models: beliefs about BC and breast self-examination by Health Belief Model (Champion, 1987), self-efficacy by Social Cognitive Theory (Umphrey, 2004), subjective norm by Theory of Planned Behaviour (Ajzen, 1991), the stages of Transtheoretical Model (Prochaska, DiClimente, 1992; adopted by Champion 1995). Cronbach's alpha coefficients 0.7-0.9. The data was conducted using conditional logistic regression model analysis (Hayes, 2011).

 

Results

The higher self-efficacy has an indirect impact to predict performance of BSE through the higher perceived severity of breast cancer. The higher subjective norm has an indirect impact to predict higher intention to perform BSE through the higher perceived benefits BSE and susceptibility of BC. The higher level of risk to develop breast cancer and higher level of knowledge moderate the relationship between beliefs and regular BSE.

 

Conclusion

The results showed that none of analysed components had a direct impact on BSE. Beliefs about breast cancer and BSE, as mediators, play an indirect but important role at performing BSE. Breast cancer preventive activities and support should include working with individual woman´s beliefs by helping her to perceive her own susceptibility to get breast cancer. Also, information materials (e.g. brochures) should be focused on emphasizing the severity of breast cancer and the benefits of BSE as a solution to prevent it.
