基于技术接受模型的肝癌筛查技术扩散利用影响因素研究

Research on influencing factors of the diffusion and utilization of technology for liver cancer screening-basing on technology acceptance model

目的基于技术接受模型,探讨肝癌早期筛查技术在临床医师中扩散利用的影响因素。方法采用多阶段抽样的方法选取调查对象,并以异常凝血酶原(DCP)检测技术为例,开展结构化问卷调查,采用结构方程模型进行数据分析。结果感知易用性正向影响感知有用性(β=0.899,P<0.001)和使用态度(β=0.223,P<0.05);感知有用性正向影响使用态度(β=0.652,P<0.001)和行为意向(β=0.413,P<0.001);使用态度正向影响行为意向(β=0.511,P<0.001);行为意向正向影响使用DCP检测技术的行为(β=0.237,P<0.01)。在感知易用性和使用态度之间以及感知有用性和行为意向之间,均存在部分中介效应。结论使用态度是影响DCP检测技术扩散利用的重要因素,而使用态度由感知有用性和感知易用性共同决定。建议技术开发组织和利用组织更关注产品性能,并为新技术的扩散利用设置技术顾问,减少使用障碍。

Objective To investigate the influencing factors of the diffusion and utilization of technology for liver cancer screening among clinicians based on the technology acceptance model.Methods A multi-stage sampling method was applied to select the respondents.The des-γ-carboxy prothrombin(DCP)detection technology was taken as an example to conduct a structured questionnaire survey,and structural equation modeling was used for data analysis.Results Perceived ease of use positively affected perceived usefulness(β=0.899,P<0.001)and usage attitude(β=0.223,P<0.05);perceived usefulness positively affected usage attitude(β=0.652,P<0.001)and behavioral intentions(β=0.413,P<0.001);usage attitude positively affected behavioral intentions(β=0.511,P<0.001);behavioral intention positively affected the behavior of using DCP(β=0.237,P<0.01).There was a partial mediating effect between perceived ease of use and usage attitude,and a partial mediating effect between perceived usefulness and behavioral intention.Conclusion Usage attitudes are important factors influencing the diffusion of DCP detection technologies,and usage attitudes are determined by both perceived usefulness and perceived ease of use.It is recommended that technology manufacture and utilization organizations should focus on technology performance,allocate technical advisers for promoting new technologies,and reduce barriers to their use.
