User psychological states and enterprise information systems adoption: evidence from the United States, Zimbabwe, South Korea, and Paraguay

The availability of low-cost Software-as-a-Service (SaaS) has made personal characteristics important in understanding technology adoption. This study examines how positive psychological capital (PsyCap) affects adoption of enterprise information system (EIS) using the Technology Acceptance Model (TAM). Data from 329 users was analyzed using structural equation modeling, finding perceived ease of use and usefulness influenced adoption intentions. Users with high PsyCap are more likely to adopt if they perceive the system as useful, while those with low PsyCap are not influenced by perceived ease of use or usefulness. Understanding personal characteristics like PsyCap is important in promoting EIS adoption.
