Analysing the Validity of Union Commitment Scale Using Confirmatory Factor Analysis with Malaysian Samples

Abstract

This study was carried out to confirm the validity of the union commitment scale proposed by Bayazit in measuring union commitment among union officials. Union commitment was represented using three sub-constructs namely loyalty towards union (12 items), willingness to work for the union (4 items) and responsibility towards union (4 items). The scale was modified to cater for the respondents consisting of union officials and local environment. A total of 676 respondents' namely union officials from the states of Selangor and Federal Territory (Putrajaya and Kuala Lumpur), Malaysia who were involved as the research subjects had been selected using stratified random sampling technique. Confirmatory factor analysis (CFA) was conducted using the AMOS software version 21. Initially, the measurement model of union commitment had demonstrated poor-fit indices whilst the correlation between sub-constructs was shown to be high. However, after undergoing the goodness-of-fit, results for the fit indices for measurement model were found to have been improved. The evaluation on the validity and reliability has also been performed for the measurement model. The number of items remaining for modified measurement model was 13, with 7 items for loyalty towards union, 2 items for the willingness to work for the union and 4 items for responsibility towards the union. Therefore, this scale which had undergone the CFA process is valid as the measurement tool to assess the level of commitment among union officials.
