摘要：The usage of Information system (IS) in any institution is vital and this human technology interaction is the heart of many world-changing endeavors. The aim of this research is to perform instrument validation through exploratory factor analysis (EFA) of using e-procurement. The questionnaire used in this study is adapted from two different studies: Venkatesh et al., (2012) and Norzaidi (2008). It consists of five sub-constructs; after the questionnaire was distributed, 115 responses were collected to do the EFA. EFA was done for each construct separately. The results show that all of the seven constructs have one component or dimension, the factor loading for every item in each construct is >0.6, Bartlett’s Test of Sphericity was <0.05 for all the constructs, which is Significant (P-value < 0.05). Kaiser-Meyer-Olkin Measure of Sampling Adequacy was higher than 0.6 for all the constructs, and this means that the sample size is adequate. Cronbach’s Alpha test was higher than 0.7 for the entire constructs’ items, which means that these items are all reliable. This study found a valid and reliable instrument for measuring the usage of e-procurement to Malaysian contractors’.
