Abstract:
The objectives of this research were: 1) to study the level of behavior based on the Threefold Training (Trisikkhā) and self-control among lower secondary students at Saensuk School, Mueang District, Chonburi Province, and 2) to examine the relationship between behaviors based on the Threefold Training and self-control among the students. This study was quantitative research with a sample size of 304 students. Data were collected through questionnaires. The reliability of the self-control questionnaire was .778, while the reliability of the questionnaire on behavior based on the Threefold Training was .857. Simple random sampling was employed. Data were analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation, along with Pearson's product-moment correlation coefficient to examine relationships between variables.
The results revealed that:
1) The behavior based on the Threefold Training of the participants was at a moderate level, with an overall mean score of 3.28. When examined by sub-dimensions, Samadhi (concentration) had the highest mean score (3.47), followed by Paññā (wisdom) at 3.33, and Sīla (morality) with the lowest mean score of 3.04. All sub-dimensions were interpreted at a moderate level. The self-control of the participants was also at a moderate level, with a mean score of 3.20.
2) The behavior based on the Threefold Training showed a positive correlation with self-control, with a Pearson's product-moment correlation coefficient of 0.503, which was statistically significant at the 0.01 level. This result indicates a moderate relationship between the two variables.
