Ergonomic Risk Factors, Musculoskeletal Disorder and Passenger Comfort (in the Context of Commuter Trains in Malaysia

Abstract

The study aims to validate the research instrument for measuring the ergonomic risk factor, musculoskeletal disorders, and passenger comfort for the users who use the Commuter train as the main transportation every day to enable them to go to the desired destination. The self-administered questionnaire was distributed to the passenger by using simple random sampling. The Confirmatory Factor Analysis (CFA) procedure was carried out to validate the instruments by assessing for unidimensionality, validity, and reliability. The study also tested the proposed hypothesis using Structural Equation Model (SEM). Furthermore, the results were confirmed through the bootstrapping procedure. The finding indicated that the measurement model of this construct achieved the requirement for construct validity and reliability. The study found Musculoskeletal Disorder fully mediates the relationship between Ergonomic Risk Factors and Passenger Comfort. Further study should be conducted on the different types of public transport trains in Malaysia due to the number of users who take this public transport is increasing day by day.
