Student’s Environmental Personality and Sensitivity’s Construct Validity Analyzed by Multitrait-Multimethod

Abstract

This research was aimed at finding out whether multitrait-multimethod was an accurate tool in validating students' environmental personality and sensitivity’s construct validity A survey method was used by selecting randomly of 151 junior high school students in Jakarta. Four different types of instruments developed measured big-5 personality and environmental sensitivity which each consisted of 23 items and 18 items, with respectively its reliability coefficient was 0.850 (personality by structure scale method), 0.814 (sensitivity by structure scale), 0.839 (personality by rating scale method), and 0.763 (sensitivity by rating scale). Data analyzed by multitrait-multimethod. The research results revealed that the convergent validity provided in the mono-trait hetero-method correlation was higher than the other validity coefficients. Moreover, another finding showed that hetero-trait mono-method correlation was higher than the hetero-trait hetero-method correlation which leads to the conclusion that its construct validity for both traits was appropriate when this tool used to validate those instruments. For the best practice in doing quantitative research, this tool is appropiate applied in determining instrument validity and reliability as well, as a supplementary approach for another tool called factor analysis, either confirmatory or exploratory.
