Promoting breast cancer screening (BCS) behavior of women can lead to a reduction in mortality. The health locus
of control affects cancer screening behavior of women; however, there is not sufficient evidence regaring this issue
in Iran. The overall goal of our study is to determine the relationship of the health locus of control with the breast
cancer screening belief of Iranian Women. This is a cross-sectional study carried out on 325 women in Tehran. The
Multidimensional Health Locus of Control (MHLC), Breast Cancer Screening Belief Questionnaire (BCSBQ), and
Demographic questionnaire were used for collecting data. Statistical analyze was performed by the SPSS version 17
software. The Pearson correlation and regression model were used for data analyze. In this study, 325 women, age 18
to 75 years, participated in this study. The mean±SD of BCSBQ and MHLC score was 40.72±10.41 and 67.78±17.67
respectively. The regression analysis showed that for the one-unit increase in the Internal Health Locus of Control (IHLC),
Powerful others Health Locus of Control (PHLC), and Chance Health Locus of Control (CHLC) score (dimensions of
Health Locus of Control), the total BCSBQ scores increased 0.54, 0.31, and 0.57 respectively. For each unit increase in
age and education, the knowledge and perceptions of the BC score increased 0.05 and 0.23 units respectively. For the
one-unit increase in the IHLC, PHLC, age, and education dimensions, the attitudes towards the general health checkup
score increased 0.17, 0.1, 0.05, and 0.188 respectively. The current study provided new insights about the BCSB
of Iranian women with MHLC. In the study, all the dimensions of the health locus of control were useful in predicting
the breast cancer screening belief of the participants.
