This study investigated variables contributing to older adults' information technology acceptance through a survey, which was used to find factors explaining and predicting older adults' information technology acceptance behaviors. Four factors, including needs satisfaction, perceived usability, support availability, and public acceptance, were found using factor analysis. According to older adults' self-reported scores, the factors of needs satisfaction and support availability are relatively more important among the four factors. According to linear regression results, the factors of needs satisfaction and perceived usability are significantly related to use intention of information technology.
