การพัฒนาโมเดลเชิงสาเหตุความมีวินัยในตนเอง ของนักศึกษาระดับปริญญาตรี มหาวิทยาลัยเทคโนโลยีสุรนารี : การวิเคราะห์กลุ่มพหุ / จิตตานันท์ ติกุล = A development of the causal model of undergraduate students' self-discipline of Suranaree University of Technology : multi-group analysis / Jittanan Tikul
To study and compare the self-discipline among 4 fields of study ; to study factor affecting self-discipline ; to examine the model validity and to test the model invariance among 4 fields of study. The research sample consisted of 1,241 undergraduate students, Suranaree university of Technology. Data consisted of 3 latent variables: self-discipline, personal factor, and environmental factor; and 13 observed variables measuring those 3 latent variables. Data were collected by questionnaires having reliability for each variables ranging from .50-.83. Data analyses were descriptive statistics, Pearson's product-moment correlation, one-way ANOVA, multiple regression analysis, and LISREL multi-group analysis. The major findings were as follows 1. Self-discipline of engineering and health sciences fields of study was high, self-discipline of agricultural technology and information technology fields of study was moderate. Level of self-discipline in 4 fields of study had statistically significant difference at .01 level. A multiple comparison had 3 pairs statistically significant difference at .01 level: self-discipline of engineering was higher than information technology fields of study, self-discipline of health sciences was higher than agricultural technology fields of study, and self-discipline of health sciences was higher than information technology fields of study. 2. Seven predictors accounted for 45% of variance in self-discipline with a multiple regression coefficient of .670. 3. The causal model of undergraduate students' self-discipline of Suranaree university of Technology was valid and fit to the empirical data. The model indicated that the Chi-square goodness of fit test was 28.987, df = 31, p = .570, GFI = .996, AGFI = .989, and RMR = .057. The model accounted for 79% of variance in self-discipline. Personal factor was more effective than environmental factor. 4. The causal model of undergraduate students' self-discipline of Suranaree University of Technology indicated invariance of model form, The model indicated that the Chi-square goodness of fit test was 238.122, df = 198, p = .027, GFI = .964, NFI = .972, RFI = .956, and RMR = .057, but all parameters were not invariant among 4 fields of study.
