摘要
[目的/意义]医疗健康类APP使用过程的个人健康隐私保护是亟待解决的重要课题,对个人健康隐私关注及隐私悖论的研究不仅可以提高公众隐私保护意识,也有利于智慧医疗服务平台的隐私管控和普及应用。[方法/过程]考虑到医疗健康APP使用过程中的信息不对称性和收益不确定性,基于信念更新理论和隐私计算理论,研究预备使用、初步使用和持续使用三个阶段个人健康隐私关注对隐私披露意愿及行为的作用机理。考虑不同阶段隐私悖论作用强度的动态变化,进一步基于理性选择理论,分析个体理性程度在隐私悖论路径中的调节作用与消解效应。采用情景实验法收集317份纵向样本数据,运用偏最小二乘结构方程模型进行实证分析。[结果/结论]研究结果表明,在预备使用阶段用户信任对初步隐私关注有显著负向影响,初步使用阶段的隐私披露意愿与行为对持续使用阶段的隐私关注具有负向影响。在初步使用和持续使用阶段,“隐私关注—披露意愿—披露行为”的路径系数均为正显著,这表明两阶段均存在隐私悖论现象。其中,持续使用阶段的中介效应间接路径占比与初步使用阶段相比明显升高,这表明随着时间推移隐私悖论的作用强度有所削弱。此外,个体理性程度对初步使用阶段的隐私悖论有显著负向影响,但对持续使用阶段的隐私悖论只有部分调节作用,这表明随着使用经验的增加,理性程度的消解效应会随时间变化而减弱。
[Purpose/Significance]The protection of personal health privacy during the use of medical and health APPs is an important issue to be solved urgently.In addition to raising public awareness of privacy protec-tion,research on personal health privacy concerns and privacy paradox can help the privacy control and populariza-tion of smart medical service platforms.[Method/Process]Considering the information asymmetry and dynamic profits during the usage of medical health APP,this study investigated the effect of personal health privacy concern on privacy disclosure intention and behavior in the pre-use,initial use,and continued use stage based on the theory of belief updating and privacy calculus.To discuss the dynamic changes of the impact strength of privacy paradox at different stages,the personal rationality degree was introduced into the privacy paradox path to analyze its mod-erating and resolution effect based on Rational Choice Theory(RCT).The scenario experiment method was adopted to collect 317 longitudinal sample data,and the partial least squares structural equation modeling(PLS-SEM)was used for the empirical analysis.[Result/Conclusion]The empirical results show that users'trust in the pre-use stage has a significant negative impact on initial privacy concern,and the privacy disclosure intention and behavior in the initial use stage have a negative impact on privacy concern in the continued use stage.In the initial use and contin-ued use stage,the path coefficient of privacy concerns-disclosure intention-disclosure behavior"is significantly positive,which indicates that the privacy paradox exists in both stages.Compared with the initial use stage,the proportion of indirect paths of mediation effect in the continued use stage is significantly higher,indicating that the impact strength of privacy paradox has been weakened over time.In addition,the personal rationality degree has a significant negative effect on the privacy paradox in the initial use stage,but only partially moderates the privacy paradox in
