Abstract
The purpose of this research was to investigate the level of technology acceptance and to examine the factors influencing the Behavioral Intention to use the Portable Quality Assurance Devices (PQAD) among employees in an automotive assembly plant in Thailand. The study employed an integrated conceptual framework combining the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Task-Technology Fit (TTF) theory. The research was conducted with a sample of 261 employees who had experience working with PQAD, using a two-stage sampling method and a 5-point Likert scale questionnaire with Cronbach's alpha reliability coefficients ranging from 0.702 to 0.919. The collected data were analyzed using descriptive statistics to describe the level of technology acceptance among the sample, including mean and standard deviation. Inferential statistics, including Pearson's correlation coefficient and multiple regression analysis, were used to test the hypotheses and measure the factors influencing the Behavioral Intention to use PQAD. The results revealed that the employees' overall level of technology acceptance was high, with a mean score of 3.99 (S.D. = 0.76). The multiple regression analysis showed that all five factors of technology acceptance, namely Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions, and Task-Technology Fit, were significantly associated with the Behavioral Intention to use PQAD, accounting for 86.1% of the variance. These factors could explain 73.6% of the variance in the Behavioral Intention to use PQAD at a statistical significance level of 0.05. When considering each factor individually, Social Influence had the strongest impact on the Behavioral Intention to use PQAD. The findings indicate that employees have a high level of acceptance for PQAD technology, with Social Influence being the most significant factor in predicting their Behavioral Intention to use PQAD.
