Khomgrit Thongnak, Woragon Wichaiyo

Abstract

Intro:The research was conducted on the basis of quasi-experimental study design that aimed to make a comparison of the effect of health education teaching media design to prevent hypertension in the elderly, Namon district, Kalasin province between the experimental group and the control group, 40 persons per group. Data were collected using an interview 1 week before and after the experiment was conducted. Data analysis was performed using frequency, percentage, mean, standard deviation while paired samples t-test and independent samples t-test were used for the comparison. The statistical significance level was set at 0.05 with 95% confidence interval. Results: The study shows that: The study results revealed that the pretest and post-test mean scores of knowledge of the experimental group were 5.50 (S.D.=1.71), 9.65 (S.D.=0.48), respectively and the post-test mean score on knowledge between the experimental group and the control group were 9.65 (S.D.=0.48), 8.37 (S.D.=0.95), respectively. The mean knowledge scores were statistically significant, p=0.014 and p<0.001, respectively. The application of the theory of health belief model can be broken down into 1) the post-test mean scores of perceived susceptibility of the experimental group and the control group were 4.26 (S.D.= 0.18), 4.02 (S.D.= 0.25) respectively. The mean score of the experimental group was higher than that of the control group with statistical significance level, p<0.001, 2) the post-test mean scores of perceived severity of the experimental group and the control group were 4.34 (S.D.= 0.16), 3.79 (S.D.= 0.25), respectively. The mean score of the experimental group was higher than that of the control group with statistical significance level, p<0.001, 3) the post-test mean scores of perceived benefits to treatment and disease prevention of the experimental group and the control group were 4.38 (S.D.= 0.24), 3.70 (S.D.= 0.57), respectively. The mean score of the experimental group was higher than that of the control group with statistical significance level, p<0.001, and 4) the post-test mean scores of perceived barriers of the experimental group and control group were 4.10 (S.D.= 0.23), 3.97 (S.D.= 0.28), respectively. The mean score of the experimental group was higher than that of the control group with statistical significance level, p=0.001. Conclusion: Multimedia in the form of lecture media in combination with reliable online media from Ministry of Public Health and agencies with reliable academic sources were used, such as Facebook, YouTube or video media disseminating knowledge about hypertension or personal media with direct experience in having the disease. Questions were randomly asked to obtain the elderly’s understanding as much as possible, which may result in the different mean scores in which the post-test scores were higher than the pretest scores. The study results should be magnified in other public health agencies.
