Understanding these factors provides an opportunity to explore actions that might be taken to boost adoption by potential users. The theoretical grounding forthis research is the Technology Acceptance Model. The Technology Acceptance Model specifies the causal relationships between perceived usefulness, perceived ease of use, attitude toward using, and actual usage behavior. The research model has six constructs, and nine hypotheses were generated from connections between these six constructs. These constructs include perceived risks, experience level, and training. The findings indicate that these three external variables are relatedto the perceived ease of use and perceived usefulness of automated unit-based medication storage and distribution systems, and therefore, they have a significant influence on attitude toward the use of these systems. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins.
