This research used non-causal survey method by selecting 120 eleventh grade students of Private High School in Jakarta randomly.
There are four instruments developed to measure personality (Big Five personality) with reliability (0.796), students' attitudes towards the environment (0.561), LOC (0.602) and personal responsibility (0.861). Data were analyzed by regression and correlation. The results revealed that those three independent variables (attitudes, LOC and personal responsibility) were positively and significantly correlated with students' personalities, particularly after being tested by second order correlation. Environmental attitude, locus of control and personal responsibility variables are the biggest contributors to students’ personality variance. Changing the students’ environmental behavior will be affected by personality, therefore these three factors can be counted by the time students’ personality being built to be more positive towards the environment.
Key words: big-five personality, locus of control, personal responsibility, second-order correlation.
