Background:
Only 20-40% of U.S. women conduct breast self-examination (BSE). This Southwest Oncology Group experimental study compared the impact of three interventions on BSE compliance.
Methods:
Subjects were randomly assigned to one of three arms: (1) physician message; (2) physician message and BSE class; or (3) physician message, BSE class, and reinforcement (phone and postcard). Compliance (frequency and accuracy) was measured by interview at intake and at 6 months and by phone contact at 1 year. Logistic and multiple regression were employed.
Results:
This analysis included 2,233 subjects from six institutions. At 1 year the percentages of women doing BSE were 59, 62, and 78% for Arms 1-3, respectively; gains over intake frequency (27% average) were significant within each arm (P < or = 0.0001). At both 6 months and 1 year the differences between Arm 1 and Arm 2 average accuracy scores and the differences between Arm 2 and Arm 3 in the percentage of women doing BSE were significant (P < or = 0.0001). Findings within institutions were consistent with the overall findings.
Conclusions:
The addition of a BSE class increased accuracy over physician message alone; physician message, BSE class, and reinforcement gave the highest percentage of women doing BSE.
