Post-adoption beliefs and continuance intention of smart device use among people with physical disabilities

Abstract

BackgroundThere has been a continuous increase of smart device use among people with physical disabilities in Korea. In spite of previous research on those people’s motives to adopt smart devices, little investigation has been conducted to scrutinize post-adoption behaviors of using smart devices among people with physical disabilities. Objective/Hypothesis: Based on the post-adoption model, this study examined the relationship between post-adoption beliefs regarding smart devices and behavioral intentions toward continued use of smartphones among people with physical disabilities. Moreover, this study investigated the moderating effects of self-efficacy on the relationships among the main study variables. MethodsBoth online and paper-pencil surveys were conducted, resulting in a total of 108 questionnaires collected from people with physical disabilities. ResultsA path analysis showed that, with the exception of perceived ease of use, all variables (confirmation, perceived usefulness, and satisfaction of smart device use) had significant effects on continuance intention to use smart devices. Another main finding of this study was the significant moderating effects of general self-efficacy on the relationships among the three variables of confirmation, perceived usefulness, and continuance intention of smart devices. The relationships among the three variables were significantly stronger among people with lower levels of general self-efficacy. ConclusionsThis study’s main findings will aid the thorough comprehension of the mechanisms that lead people with physical disabilities to continue to use smart devices.
