Factors Analysis of Unified Theory of Acceptance and Use of Technology Version 2: Influence on the Regulation of Acceptance and Use of Vending Machines

The aims of research were 1) to develop a measure of acceptance and use of vending machines to meet the standard criteria, 2) to study the influence of acceptance on vending machines usage, and 3) to study the influence of moderator variables affecting acceptance on vending machines usage: gender, age, and experience. The study was conducted on 406 subjects who had used vending machines no less than twice in the past month, which serving the Bangkok and vicinity areas and derived by quota sampling method. A questionnaire was assessed for content validity index, both Item and Scale level method, and reliability by the Cronbach Alpha coefficient. Data were analyzed statistically, namely Mahalanobis d-Square, comparison of the average variance extracted with the shared variance, structural equation modeling, and multi-group analysis. The results reviewed that 1) the measurement instrument was met with the Unified Theory of Acceptance and Use of Technology; version 2 and passed the criteria for assessing validity. 2) Factors directly influencing behavior intention with statistical significance include effort expectancy, social influence, hedonic motivation, price value, and habit. Moreover, the factors directly influencing the use behavior were statistically significant, namely, habit and behavior intention, and 3) gender, and age were the variable moderate influence for 2 routes, and experience was the variable moderate influencing for 3 paths.
