In spite of previous researches in large-scale volunteerisms have explored volunteer’s theory of planned behavior (TPB), little has been known concerning the scale development of volunteers’ Satisfaction and Motivation in related to science volunteer service. This study tested an expanded TPB model with a sample of 443 volunteers taken from a project for science volunteers run by the Ministry of Science and Technology in Taiwan. To explore volunteers’ perspectives on their involvement in science service, structured questionnaires examined their attitudes, subjective norms, perceived behavioral control, Satisfaction and motivation via continued observation throughout the duration of the project. The findings from the path analyses suggest that the TPB is a useful tool for understanding event volunteers’ intention. In addition, Satisfaction emerged as the exclusive determinant of sustained volunteering and also as the potential predictor of the effects of other variables on future volunteering behavior. However, it was found that the science volunteers’ motivation had significant negative correlation with behavioral intention. In general, the expanded model of TBP provided an appropriate framework for understanding the factors associated with volunteering. Practical implications and future research directions for science volunteer management are also discussed.
