MULTIDIMENSIONAL RELIABILITY OF INSTRUMENT STUDENTS’ SATISFACTION USING CONFIRMATORY FACTOR ANALYSIS

Abstract

The purpose of this paper is to compare unidimensional reliability and multidimensional
reliability of instrument students’ satisfaction as an internal costumer. Multidimensional
reliability measurement is rarely used in the field of research. Multidimensional reliability is
estimated by using Confirmatory Factor Analysis (CFA) on the Structural Equation Model
(SEM). Measurements and calculations are described in this article using instrument students’
satisfaction as an internal costumer. Survey method used in this study and sampling used simple
random sampling. This instrument has been tried out to 173 students. The result is concluded
that the measuringinstrument of students’ satisfaction as an internal costumer by using
multidimensional reliability coefficient has higher accuracy when compared with a
unidimensional reliability coefficient. Expected in advanced research used another formula
multidimensional reliability, including when using SEM.
Keywords: multidimensional reliability, instrumentof students’ satisfaction as an internal
costumer, confirmatory factor analysis.
