Employee’s performance is agreed to be one of the important factors that can indicate the firm’s performance. Several management and psychological factors have been focused in the researches as the factors influencing job performance of the employees. Motivation is one of the most interesting factors that could influence employee’s attitudes and behaviors. This study emphasizes on Vroom’s expectancy theory which explains the motivation process from effort to performance and outcomes. The study aims to examine the valid factors affecting employee engagement and job performance in respect to expectancy model. Five motivational factors modified from the original expectancy model, i.e. expectancy, extrinsic instrumentality, intrinsic instrumentality, extrinsic valence and intrinsic valence, were focused as the factors that influence employee’s employee engagement and job performance. The survey was performed to collect data from 356 employees working in the firms from various sectors in Thailand. Structural Equation Modeling (SEM) was performed to analyze the data. The results indicate the direct influences of expectancy, extrinsic instrumentality, and intrinsic valence on employee engagement and indirect influence of the three factors on job performance while the influence of intrinsic instrumentality and extrinsic valence on employee engagement was not found. In addition, the direct influences of all expectancy-related constructs on job performance were not illustrated.
