Study Limitations and Recommendations for Future Research
The study sample was small and was conveniently selected. As a result, these findings may not be generalizable to the larger population of interest Future research should replicate- this study utilizing a larger sample size with a more diverse population of elementary school teachers in both rural and urban settings. In addition, the use of a comparison group would have added strength to the study design. The difference in the number of teachers who had prior experience with asthma and those who did not is also included as a limitation of this study due to the fact that these groups were not equal yet their differences were reported to be statistically significant. Another limitation of this study included the use of an investigator—developed instrument to measure knowledge of asthma. Further testing of this instrument is needed with larger and more diverse sample populations.
