Abstract:
The purposes of the study were 1) to compare the mean scores of health practices on personal health according to Thai National Health Recommendation before and after experiment using self- regulation concept on the experimental and control groups 2) to compare the mean scores of health practices on personal health according to Thai National Health Recommendation before and after experiment using self-regulation concept between the experimental and control groups 3) to compare the mean scores of health practices on personal health according to Thai National Health Recommendation before experiment, after experiment and one month follow-up using self- regulation concept on the experimental group. This study was a quasi-experimental research, 30 students were classified as the experimental group and the other 30 students were the control group. Students in class 3A and 3B which were in grade three of Pi Thnou Primary School were selected as the experimental and control groups by purposive selection. Two instruments were used in this study. The first one was the 14 learning activity plans, which implemented within seven weeks. The learning activity management was conducted half and hour every Wednesday and Thursday. The second one was the practice questionnaires on personal health. The content validity (IOC) of the learning activity plans equaled to 0.90 and the reliability of the questionaire was 0.70. The mean scores, standard deviation and t-test were used for data analysis. F-test (one way ANOVA) was also used to compare the mean scores of pre-test, post-test and one month follow-up test of the experimental group. Finally, Scheffé was employed to test the differences of pair wise comparisons with the statistically significant at the .05 level. This study had been approved by National Ethic Committee for Health Research in Cambodia. The study findings were as follows: 1. After experiment, the mean scores of health practices of the experimental group (2.62) were found statistically higher significances than before experiment (2.48) at the .05 level. However the mean scores of health practices of the control group were found no statistically significant differences between before and after experiment. 2. Before experiment, the mean scores of health practices between the experimental group (2.48) and control group (2.46) were found no statistically significant differences at the .05 level. On the other hand, after experiment, the mean scores of health practices on personal health between the experimental group (2.62) and control group (2.50) were found statistically significant differences at the .05 level. 3. The mean scores of the health practices on personal health in the experimental group after experiment and one month follow-up were found statistically higher significances than before experiment. On the other hand, the mean scores between one month follow- up and after experiment were found no statistically significant differences at the .05 level.
