The purpose of this study was to investigate the effects of health belief model instruction on breast self-examination compliance in perimenopausal women. Quasi-experimental research was implemented. The sample comprised of 60 women attending for the first time at the menopausal clinic, Hatyai Hospital. Subjects were purposively assigned into 2 groups. The first 30 subjects were a control group who received routine care from the hospital personnel and the next 30 subjects were the experimental group who received instruction from the researcher. The research instruments were lesson plan about breast cancer and breast self-examination, video and handbook of breast self-examination, and breast model for demonstration and return-demonstration of breast self-examination practice. The data were collected as pretest-posttest time series using a questionnaire covering
health beliefs based on the model developed by Becker, and evaluation of breast self-examination compliance. Frequency and percentage were used in descriptive data analysis. The results of health belief model instruction of breast self-examination compliance within each group before and after routine care or instruction the test (at 3 time periods : 3 weeks, 6 months and 12 months later) were
tested using non-parametric statistics, Friedman test. Differences between groups after the routine
care or instruction were analyzed using Mann-Whitney U test.
It was concluded that:
1. There was no statistical difference in mean rank scores of health belief model before and
after the routine care in the control group.
2. There was no statistical difference in mean rank scores of health belief model before and
after the instruction in the experimental group.
However, when the health belief model of the experimental group was analyzed in more detail, it was found that confidence in conducting a breast self-examination after the instruction was significantly greater than before.
3. There was no statistical difference in mean rank scores of health belief model after the
routine care or instruction between the control group and experimental group.
However, when the health belief model was analyzed in more detail, it was found that perceived risk of breast cancer after the instruction was significantly higher in the experimental group (p<0.05). And health motivation at the first post instruction was also significantly higher (p<0.05).
4. The breast self-examination compliance in the control group revealed that there were changes in the frequency of breast self-examination before and after the routine care. There was also a statistically increase in mean rank scores of breast self-examination practice (p<0.05).
5. The breast self-examination compliance in the experimental group revealed that there were changes in the frequency of breast self-examination before and after the instruction. There was also a statistically significant increase in mean rank scores of breast self-examination practice (p<0.05).
6. The breast self-examination compliance between the control group and experimental group revealed that there were changes in the frequency of breast self-examination after the routine care or instruction. The mean rank scores of breast self-examination practice in the experimental group was significantly higher than in the control group (p<0.05).
