The study objectives of the electrical energy saving behavior of student in faculty of business administration Rajamangala University of Technology Phra Nakhon 1) to study psychological trait factor psychological state factor and situational factor in overall group and subgroup of the students’ electrical energy saving behavior in faculty of business admimistration RMUTP 2) to study the interaction effect between psychological trait factor psychological state factor and situational factors related to the students] electrical energy saving behavior in overall group and subgroup. The sample size was 361 students of bachelor’ s degree. The study factors were 7 independents future orientation and self-control) 1 psychological state factors (appropriate model from family knowledge on the electrical energy saving and the information about electricity saving). The dependent factor was the electrical energy saving behavior. Frequency percentage arithmetic mean and standard deviation were used for descriptive statistic while stepwise multiple regression and two-way ANOVA were used for inferential statistics in overall group and subgroup according to social demographic characteristics. The research findings were as follows : Firstly all 7 factors of psychological trait factors psychological state factor and situational factoe could predict 52% of variance of the electrical energy saving behavior. The most prediction power factors were appropriate model from family positive attitude towards saving behavior receives electricity saving information and well-being respectively. Secondly the interaction effect was found well-being and electricity saving information with the electrical energy saving behavior of student which was male and female group and freshman and sophomore group junior and senior group G.P.A above 3.00 and parents’ income lower than 30000 thb Thirdly the interaction effect was found the future orientation and self-control and knowledge on the electrical energy saving behavior with the group of student who mother has an education lower than undergraduate.
