Most subjective measures used in practice are unvalidated, and their relationship to system usage is unknown.

Perceived Usefulness, Perceived Ease of Use, and User Acceptance of Information Technology Author(s):. (Davis, 1986).Note: In calculating the moving wall, the current year is not counted.Perceived Usefulness, Perceived Ease of Use, and User Acceptance of Information Technology.Regression analyses suggest that perceived ease of use may actually be a causal antecedent to perceived usefulness, as opposed to a parallel, direct determinant of system usage.Note: Always review your references and make any necessary corrections before using.In both studies, usefulness had a significantly greater correlation with usage behavior than did ease of use.

The measures were refined and stream-lined, resulting in two six-item scales with reliabilities of.98 for usefulness and.94 for ease of use.Health professionals are increasingly encouraged to adopt an evidence-based practice to ensure greater efficiency of their services.
