Factors associated with screening mammography and breast self-examination intentions

The factors associated with the use of two methods for the early detection of breast cancer were assessed using a theoretical framework derived from the theory of reasoned action and the Health Belief Model. Telephone interviews were conducted with 170 women aged between 50 and 70 years, randomly selected from the telephone directory of a provincial city in Victoria, Australia. The model explained 47% of the variance in intentions to have a mammogram and 22% of the variance in intentions to practise breast self-examination (BSE). The data supported the prediction that different variables would be associated with each method of early detection of breast cancer. Intentions to have a mammogram were associated with perceived susceptibility to breast cancer, knowing a woman who has had a mammogram, previous mammography history and Pap test history. Intentions to do BSE were associated with self efficacy, knowledge of breast cancer issues, concern about getting breast cancer and employment status. Both screening methods were associated with prior behaviour and concern about getting breast cancer.
