人工智能嵌入带来的威胁感知日益受到广泛关注,探讨威胁感知对工作状态的影响机制,对提升组织技术融合效能具有重要意义。基于自我决定理论,从员工自我效能感和工作自主性视角,构建威胁感知对工作繁荣的双重影响机制,并强调新技术接受...人工智能嵌入带来的威胁感知日益受到广泛关注,探讨威胁感知对工作状态的影响机制,对提升组织技术融合效能具有重要意义。基于自我决定理论,从员工自我效能感和工作自主性视角,构建威胁感知对工作繁荣的双重影响机制,并强调新技术接受度在其中的关键作用。通过问卷法收集355份有效样本,采用SPSS 27.0和AMOS 28.0对数据进行信度与结构效度检验,并运用SPSS Process 4.0对理论模型进行检验。研究结果表明:一方面,威胁感知通过降低自我效能感削弱员工工作繁荣;另一方面,威胁感知通过提升工作自主性促进员工工作繁荣。此外,新技术接受度不仅能调节威胁感知对自我效能感的负向影响,还能增强威胁感知对工作自主性的正向影响。研究为理解人工智能时代员工认知与决策反应提供理论依据,并为企业有效应对人工智能嵌入带来的挑战,促进员工工作繁荣提出实践启示。展开更多
目的探讨北京市老年微信用户的新媒体健康信息使用意愿和行为的影响因素。方法2022年3—4月采用方便抽样法选择北京市≥60岁的老年微信用户为研究对象,通过自我效能理论和整合技术接受与使用理论(the Unified Theory of Acceptance and ...目的探讨北京市老年微信用户的新媒体健康信息使用意愿和行为的影响因素。方法2022年3—4月采用方便抽样法选择北京市≥60岁的老年微信用户为研究对象,通过自我效能理论和整合技术接受与使用理论(the Unified Theory of Acceptance and Use of Technology,UTAUT)编制量表进行问卷调查,量表信效度良好,通过通径分析验证健康信息使用意愿和行为的影响因素。结果共1006名老年微信用户纳入分析,UTAUT各因素和自我效能得分为3.01~4.02(5分制),相应的得分率为60.2%~80.4%,处于及格至中等水平。全部样本的通径分析模型拟合良好,χ^(2)值为4.64,自由度为4,P=0.326,近似误差均方根=0.022,调整拟合优度指数=0.990,对健康信息使用行为、使用意愿和自我效能的解释度分别为31.0%、64.0%和53.0%。绩效期望(β=0.20)、努力期望(β=0.23)、社会影响(β=0.21)和促进因素(β=0.27)均对使用意愿产生直接作用,前两者还通过自我效能间接影响健康信息使用行为(间接效应分别为0.16和0.11)。使用行为的直接影响因素包括使用意愿(β=0.07)、自我效能(β=0.25)和社会影响(β=0.21)。年龄和性别在不同路径上的调节作用不尽相同。结论UTAUT和自我效能可以用来解释老年微信用户的健康信息使用意向和行为,未来通过新媒体开展老年人健康教育,需要通过提高使用价值感并降低使用难度来增强其自我效能感,并进行人群细分,以进一步增强新媒体健康传播效果。展开更多
