User Compliance With the Health Emergency and Disaster Management System: Systematic Literature Review.

BACKGROUND: Health-related hazards have a detrimental impact on society. The health emergency and disaster management system (Health EDMS), such as a contact-tracing application, is used to respond to and cope with health-related hazards. User compliance with Health EDMS warnings is key to its success. However, it was reported that user compliance with such a system remains low. OBJECTIVE: Through a systematic literature review, this study aims to identify the theories and corresponding factors that explain user compliance with the warning message provided by Health EDMS. METHODS: The systematic literature review was conducted using Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 guidelines. The search was performed using the online databases Scopus, ScienceDirect, ProQuest, IEEE, and PubMed, for English journal papers published between January 2000 and February 2022. RESULTS: A total of 14 papers were selected for the review based on our inclusion and exclusion criteria. Previous research adopted 6 theories when examining user compliance, and central to the research was Health EDMS. To better understand Health EDMS, based on the literature reviewed, we mapped the activities and features of Health EDMS with the key stakeholders involved. We identified features that require involvement from individual users, which are surveillance and monitoring features and medical care and logistic assistance features. We then proposed a framework showing the individual, technological, and social influencing factors of the use of these features, which in turn affects compliance with the warning message from Health EDMS. CONCLUSIONS: Research on the Health EDMS topic increased rapidly in 2021 due to the COVID-19 pandemic. An in-depth understanding of Health EDMS and user compliance before designing the system is essential for governments and developers to increase the effectiveness of Health EDMS. Through a systematic literature review, this study proposed a research framework and identified research gaps for future research on this topic.

Reviewer's communication style in YouTube product-review videos: does it affect channel loyalty?

Product-review videos can be a promising marketing method. The popularity of using videos as a medium for product reviews is evidenced by the number of channels that are used to provide product reviews on multiple platforms. Reviewers can use various strategies to attract wider audiences and make these audiences loyal to their channels. This study analyzes the effect of the reviewer's communication style on the audience's loyalty to the channels that provide product reviews, especially on the YouTube platform. Communication-style analysis is associated with hedonic and utilitarian motivation theory, which can be used to explain communication style effect on channel loyalty. This study uses a quantitative approach using questionnaire to obtain data. The data in this study are analyzed using covariance-based structural equation modeling in AMOS 21.0. The results show that communication styles (social-oriented and task-oriented), perceived transparency, perceived enjoyment, credibility, and channel engagement affect channel loyalty. Meanwhile, the informativeness factor does not affect channel loyalty. This paper will also discuss the theoretical and practical implications of the study.
