Information technology (IT) is an important component of medical informatics. Information needs to be accepted by users to function effectively. At different ages and from different views, several models have been proposed and used to show factors affecting users' IT acceptance. However, such models are in need of frequent revision and development due to variable conditions.
The present research aims to design a new health IT acceptance model from Iranian users' views. The research aims both to design a model for status quo by reviewing previous models and consider features of Iranian users.
This is a correlative, cross-sectional study. Firstly, the primary model was presented by studying important IT acceptance models. Then, a structured questionnaire was designed and, after confirmation of validity and reliability of the questionnaire, it was given to users of information and health IT systems in different wards of hospitals in Iran. Data were analyzed by SPSS and Lisrel and the final model was designed by structural equations.
The model showed that there are six key factors which are effective on attitude and use intention including performance expectancy, observability, effort expectancy, facilitating conditions, empowerment and subjective norms via three interface factors of perceived usefulness, perceived ease of use, self-efficacy. The size of technology use is an important factor in technology acceptance and application as well.
The present model has more details compared to the other models and can show a new image of important factors in technology acceptance and their relationships.
信息技术（IT）是医学信息学的重要组成部分。信息需要被用户接受才能有效发挥作用。从不同年龄和不同视角出发，已经提出并使用了多种模型来展示影响用户对IT接受度的因素。然而，由于情况多变，此类模型需要不断修订和发展。
本研究旨在从伊朗用户的视角设计一个新的健康IT接受模型。该研究既要通过回顾以往模型来设计一个现状模型，又要考虑伊朗用户的特征。
这是一项相关性横断面研究。首先，通过研究重要的IT接受模型提出初始模型。然后，设计一份结构化问卷，在确认问卷的有效性和可靠性后，将其分发给伊朗不同医院病房的信息和健康IT系统用户。数据通过SPSS和Lisrel进行分析，最终模型通过结构方程设计得出。
该模型表明，有六个关键因素通过感知有用性、感知易用性、自我效能这三个界面因素对态度和使用意愿产生影响，包括绩效期望、可观察性、努力期望、促进条件、赋能和主观规范。技术使用规模也是技术接受和应用中的一个重要因素。
与其他模型相比，本模型有更多细节，能够展现技术接受中重要因素及其关系的新图景。
