Understanding and predicting the use of information technology is an important problem in healthcare management. The relationships among user characteristics and information technology have generally been weak. This paper describes a recently developed scale that measures perceived usefulness of information technology. Following this description, the scale is compared with user age in ability to explain information technology use. The results suggest perceived usefulness explains a significant proportion of the variance in use (r2 = .13, p < or = 0.0001), while age was not a significant predictor. Implications and suggestions for use of the usefulness scale are discussed.
理解和预测信息技术的使用是医疗管理中的一个重要问题。用户特征与信息技术之间的关系通常较弱。本文描述了一种最近开发的衡量信息技术感知有用性的量表。在此描述之后，将该量表与用户年龄在解释信息技术使用能力方面进行了比较。结果表明，感知有用性解释了使用差异中的很大一部分（r2 = .13，p ≤ 0.0001），而年龄不是一个显著的预测因素。文中讨论了使用该有用性量表的意义和建议。
