The effectiveness of protection motivation theory to behavioral modification to reduce the risk of coronary heart disease among upper secondary male students in schools under Bangkok Private Education Office
Abstract:
Cardiovascular disease is one of the major causes of death in Thailand. This
non-communicable disease is on the rise in Thailand, and the most prevalent is
Coronary Heart Disease. Overweight students are at risk of this disease because of
unhealthy eating behavior and lack of exercise.
This quasi-experimental study was designed to document the effectiveness
of a health education program using Protection Motivation Theory to reduce the risk
of Coronary Heart Disease. The program used modeling, lectures, exercise
demonstrations, eating practices and group processes. The study sample was
comprised of 80 male students aged 15-16 years studying in upper secondary schools
under Bangkok Private Education Office.The sample was selected by simple random
sampling and was evenly divided into two groups: an experimental and a comparison
group. The study was carried out for 14 weeks from November 2000 to January
2001. Data were collected by using a questionnaire, measuring bodyweight, height,
resting pulse, and recovery rate. Statistical analysis included frequency, percentage,
arithmetic mean, standard deviation, paired t- test, and independent t- test.
Results showed that after participating in the health education program, the
experimental group had a significant change in their perceived severity and
susceptibility to coronary heart disease, self-efficacy, response efficacy and
demonstrated behavioral change to reduce coronary heart disease to a greater extent
than the comparison group. It was also found that the experimental group had a lower
pulse rate at rest and shorter recovery time than the comparison group after
participation in the program. Furthermore, the experimental group had marginally
lower bodyweight than the comparison group.
The study revealed that a health education program utilizing the Protection
Motivation Theory and group processes yielded positive changes in behavior to
reduce coronary heart disease. Thus, this program should be applied to other similar
target groups and in other schools.
