即时反馈总是更好吗?隐私反馈即时性对隐私增强服务使用的双重影响研究OACHSSCD

[Purpose/Significance]Privacy-enhancing technologies(PETs)have emerged as a crucial tool for balancing user privacy and data utility.However,their adoption remains limited,largely due to the inherent intangibility and unverifiability of privacy protection,which hinders users'real-time perception and valuation of PETs'efficacy during interaction.Immediate feedback,typically presented as real-time prompts showcasing protective actions,is posited as a potential solution to make protection tangible.Nevertheless,prior research on feedback timing presents inconsistent findings and is predominantly confined to single-task contexts.A critical gap exists in understanding how feedback timing ope-rates within the more prevalent and complex multi-task scenario,where PETs interaction typically occurs as a secondary task nested within primary activities such as shopping or entertainment.The paper aims to bridge this gap by investigating the dual impact of privacy feedback immediacy on the use of privacy-enhancing services,along with the underlying mecha-nisms and boundary conditions.[Method/Process]Grounded in goal conflict theory,the study integrated protection motiva-tion theory and perceived intrusiveness to construct a dual-path model.This model was empirically tested through a scenario-based experiment.The study recruited 147 participants from a public university in China.After excluding four participants who failed attention checks,the study obtained 143 valid responses for analysis.Data were analyzed using R(version 4.3.2),primarily employing the bruceR package to test the proposed mediation and moderation effects.[Result/Conclusion]The findings reveal that immediate privacy feedback has a"double-edged sword"effect on user adoption of privacy-enhancing services.While it enhances users'coping appraisal of privacy protection,it simultaneously triggers a higher level of perceived intrusiveness.These two paths jointly influence user adoption of the service.Moreover,the ser-vice context significantly moderates the strength of these two pathways,leading to opposite effects in utilitarian versus hedonic contexts.The paper makes several important contributions to the literature.First,it introduces a novel user inter-action perspective to the study of PET adoption,specifically focusing on the timing of privacy feedback as a key determi-nant,which enriches the literature on influencing factors of PETs adoption.Second,this study extends the research on feedback provision from the universally focused single-task setting to a multi-task scenario,thereby broadening the appli-cability boundary of privacy feedback timing and providing a new explanatory perspective for understanding the mechanism of feedback timing in complex multi-task contexts.Finally,by introducing utilitarian and hedonic service contexts,the research identifies boundary conditions that influence the efficacy of immediate privacy feedback.Furthermore,the paper offers practical recommendations for organizations to optimize the interactive design of privacy-enhancing services,which would help enterprises promote privacy-enhancing services more effectively and foster a healthy privacy protection environment.
