This research aims to: 1) study the direct and indirect influences of factors affecting the environmental conservation behaviors of Praboromarajchanok Institute students; and 2) develop a causal relationship structure model of the environmental conservation behaviors of the students under Praboromarajchanok Institute by developing elements from the theories of planned behavior, protection motivation theory, and value-belief-norm theory. This research is survey research. The sample group for this research was 480 students under the Praboromarajchanok Institute from 8 colleges, which were obtained by multi-stage sampling. The research variables consisted of 7 latent variables, including attitude toward environmental behaviors, perceived efficacy in environmental behavior control, perceived threats to environmental behaviors, personal values, subjective norms, environmental behavior intention, and environmental conservation behaviors. All latent variables were measured from 24 observed variables using a questionnaire. The statistics used in data analysis were frequency, percentage, mean, standard deviation, and causal relationship structure model analysis.

The results of the research revealed that the level of environmental conservation behaviors of the students under Praboromarajchanok Institute was high, and the results of the analysis of the causal structure relationship of the environmental conservation behaviors of students under Praboromarajchanok Institute fit with the empirical data and could explain 78% of the variance in environmental conservation behaviors of students under Praboromarajchanok Institute. Personal value had the highest effect on the environmental conservation behavior of the students, followed by environmental behavior intention, subjective norms, perceived environmental behavior control, perceived threats to environmental behaviors, and attitude towards environmental behaviors, respectively. In addition, it was found that attitude towards environmental behaviors, subjective norms, and perceived threats to environmental behaviors directly influenced environmental behavior intention. The perceived efficacy of environmental behavior control directly influenced environmental behavior intention and environmental conservation behaviors. For personal values, there was an indirect effect on environmental conservation behaviors through perceived efficacy in environmental behavior control, attitude toward environmental behaviors, subjective norms, perceived threats to environmental behaviors, and environmental behavior intention. Furthermore, environmental behavior intention was found to have a direct influence on environmental conservation behaviors.
