Abstract

Personality possesses close ties with character education or building. A student that studied character building will be able to apply pro-environmental behaviors. An instrument is needed to determine a students’ environmental personality, and the most important trait in a test/instrument is validity. Item validity is used to measurement to improve it, where accurate measurement is obtained not only through item accuracy but also through the effects of the options number and sample size. This study aims to uncover the difference between the item validity of students’ environmental personalities with the options number and sample size. The data are analyzed by using a two-way ANAVA with Tukey post-hoc test. The results of this study show that (1) Students environmental personality’s item validity is affected by the number of options, (2) the item validity of students’ environmental personality is not affected by sample size, (3) There is an interacting influence between the number of options and sample size on the item validity of the students’ environmental personality score. Based on the Tukey test we discovered that the group working in 3 options with a sample size of 175 students, differed compared to other groups significantly. In conclusion, the highest item validity for students’ environmental personality test is achievable on the group that uses three options with a sample size of 175 students.
