Online information seeking: a review of the literature in the health domain

The development of the information technology and Internet has been transforming the healthcare industry. The internet is continuously accessed to seek for health information and there are variety of sources, including search engines, health websites, and social networking sites. Providing more and better information on health may empower individuals, however, ensuring a high quality and trusted health information could pose a challenge. Moreover, there is an ever-increasing amount of information available, but they are not necessarily accurate and up to date. Thus, this paper aims to provide an insight of the models and frameworks related to online health information seeking of consumers. It begins by exploring the definition of information behavior and information seeking to provide a better understanding of the concept of information seeking. In this study, critical factors such as performance expectancy, effort expectancy, and social influence will be studied in relation to the value of seeking health information. It also aims to analyze the effect of age, gender, and health status as the moderator on the factors that influence online health information seeking, i.e. trust and information quality. A preliminary survey will be carried out among the health professionals to clarify the research problems which exist in the real world, at the same time producing a conceptual framework. A final survey will be distributed to five states of Malaysia, to solicit the feedback on the framework. Data will be analyzed using SPSS and SmartPLS 3.0 analysis tools. It is hoped that at the end of this study, a novel framework that can improve online health information seeking is developed. Finally, this paper concludes with some suggestions on the models and frameworks that could improve online health information seeking

Trust and risk in consumer acceptance of e-services

Thesis (Ph.D. (Information Systems))--University of the Witwatersrand, Faculty of Commerce, Law & Management, School of Economic and Business Sciences, 2015Electronic services (or e-services) are defined as any service whose delivery is based on Internet, IT and communications technology, and which incorporates a large self-service component. They offer consumers the promise of increased convenience, lower-cost of transacting, greater choice and accessibility by eliminating space and time constraints to their interactions with service providers. Benefits of e-services cannot however materialize without consumer acceptance. Unfortunately, uncertainty and fears of opportunism still characterize the online context and varying degrees of consumer acceptance and engagement in use of e-services has thus been observed. The extant literature considers consumer perceptions of risk and their trust beliefs amongst the most important psychological states influencing their online behavior. However, despite the number of empirical studies that have explored the effects of trust and risk perceptions on consumer acceptance of e-services, the field remains fragmented and the posited research models are contradictory. For example, the trust-risk relationship has been modeled differently in past studies and the causal relationship between trust and risk perceptions has not been clarified. In addition, research into the antecedents of trust has not been integrated to provide an answer as to which are the most significant antecedents. Furthermore, past research has paid more attention to initial trust or risk perceptions and has not adequately examined whether these perceptions change over time or how they come to influence later stage acceptance of e-services. To address these gaps in our understanding of trust and risk in consumer acceptance of e-services, this thesis adopted three research designs, namely meta-analytic approaches, cross-sectional surveys and longitudinal designs. First, a meta-analytic study1 was used to aggregate empirical findings from across prior studies in e-service. This allowed the nature of the relationship between trust, perceived risk, and acceptance of e-services to be synthesized and for competing nomological models of the trust-risk-acceptance relationship to be compared. 52 studies were examined and it was found that trust is most important to form consumer positive attitude for acceptance. By comparing competing models, it found that trust and risk are significantly related and trust may influence risk in consumer acceptance of e-services. 1 Presented at 34th International Conference on Information Systems (ICIS 2013), Milano, Italy. iv Moderator analysis within the meta-analysis was also carried out to determine if different types of consumer cultures (e.g., Western versus Eastern), different types of e-services (e.g., commercial versus non-commercial), or different objects of trust (e.g., trust in vendor versus trust in website technology) influence the relationships between trust, risk and acceptance of e-services. Furthermore, the antecedents of trust as suggested by past research were examined via a second meta-analysis of 59 prior studies2. The antecedents of trust were classified as vendor and institution-based antecedents, technological-based antecedents, knowledge-based antecedents, and consumer characteristics-based antecedents. Technological-based antecedents were found the most significant antecedents of trust. For all antecedents, studies classified as having been carried out in Eastern cultures reported on average stronger effect sizes than those carried out in Western cultures. In addition to the meta-analytical studies, this thesis also carried out cross-sectional and longitudinal investigations to study trust and risk in an understudied context of e-services, namely consumer acceptance of online health information services. The motivation to adopt this context is because previous studies of e-services were mostly focused on commercial (e.g., e-commerce, e-shopping and e-banking, etc) and mostly on non-commercial context such as e-government. However, e-health services are relatively under-explored. Moreover, the Web has become an important health information dissemination channel. People are increasingly searching for health information online and engaging in the self-management of their health. Trust and risk are considered important to the online health context, and it therefore served as an appropriate e-service context for empirical analysis. Two cross-sectional studies3,4 were carried out to explain user acceptance of online health information services. This cross-sectional work was underpinned by multiple theoretical perspectives namely Theory of Reasoned Action (TRA), Health Belief Model (HBM) and Extended Valence Framework (EVF). Findings showed that multiple dimensions of trust (trust in provider, trust in website and trust in institutional structures) have both direct and indirect effects, via perceived usefulness, on consumer acceptance. 2 Presented at 18th Pacific Asia Conference on Information Systems (PACIS 2014), Chengdu, China. 3 Forthcoming at 35th International Conference on Information Systems (ICIS 2014), Auckland, New Zealand. 4 Forthcoming at 25th Australasian Conference on Information Systems (ACIS 2014), Auckland, New Zealand. v One-dimensional risk was not found to have a significant influence on consumer acceptance. However, multi-dimensional risk (performance risk, psychological risk and time risk) did combine with health belief variables such as perceived susceptibility and severity to influence consumer acceptance. Because cross-sectional data is limited in its ability to address causal connections amongst phenomena, two longitudinal investigations were also carried out. These investigations were used to explain whether trust beliefs and risk perceptions change over time in consumer acceptance of e-services, how early stage trust and risk perceptions influence later stage acceptance and usage behaviors, and whether there is reciprocal causality between trust and risk perceptions. This work was underpinned by TRA and Expectation-Confirmation Theory (ECT), and employed both path modeling and cross-lagged structural equation modeling techniques. The results showed that trust, risk perceptions and perceived usefulness are important to the prediction of consumer acceptance of online health services at both the early and later usage phases5. Furthermore, trust in provider and trust in website have reciprocal relations and empirical data supported the influence of risk perceptions on trust. Through the meta-analytic design, cross-sectional approaches and longitudinal designs, this thesis contributes to research on e-services in a number of ways. First, meta-analytic approaches integrated the available evidence from prior studies, which resulted in the generation of a dataset which was larger in scope and scale than could feasibly be achieved in any single research study. This dataset could then be used to compare competing nomological models found in the literature. In so doing, results have improved our understanding of how trust and risk are related, how they combine to influence consumer acceptance, as well as identifying the most important antecedents of trust. Results provide a benchmark against which future studies can compare their effect sizes. Moreover, by examining the heterogeneity of effect sizes, the meta-analysis has also identified moderators that can account for observed inconsistencies in the effect sizes reported by prior studies. Together, the findings have extended our understanding of how trust and risk relate to e-service acceptance in different e-service contexts, across 5 Presented at 18th Pacific Asia Conference on Information Systems (PACIS 2014), Chengdu, China. vi different consumer cultures, and whether trust in the vendor or technology platform has relatively greater importance to consumers. Second, this thesis also integrated trust into HBM to examine online health information seeking as both a health behavior and online consumer behavior. Results help us better understand this specific case of e-service acceptance. Third, this study is also the first to develop and validate a dynamic trust and risk model in consumer acceptance of online health information services. The longitudinal design integrates trust into the theoretical framework of TRA and ECT to develop the dynamic research model. Tests of the model have made a key contribution to the development of a theory that explains the dynamic nature of e-service acceptance. Furthermore, the cross-lagged longitudinal design contributed to our understanding of the casual relationship between consumers’ trust and risk perceptions in the context of online health information services. Taken together this thesis illustrates how meta-analysis and structural equation modeling can be integrated together to approach the fragmented and contradictory nature of the field. Moreover, this thesis addresses the lack of longitudinal studies on acceptance, and presents a novel method, cross-lagged structural equation modeling, to examine controversial causal relationships within the field of Information Systems. This thesis also has important practical implications. It provides insights into the relative importance of trust and risk perceptions necessary to inform practitioners on risk reduction and trust-building mechanisms. The investigation into the antecedents of trust reveals especially important factors which are within the control of e-service providers. With this understanding, practitioners can be better positioned to establish their online service offerings. Website designers can also benefit from understanding the extent to which particular antecedents of trust (e.g., ease of use and system quality) are important for e-service acceptance. By studying the online health information services context, this thesis has also shed light on the general perceptions and attitudes of consumers towards this high-potential area of e-service

Improving online food safety communication: The role of media

Food safety is important as foodborne illness outbreaks cause great economic and societal losses. Efforts to protect public health and reduce foodborne illness outbreaks will not be fully effective unless the resulting information is communicated to consumers. However, food safety communications have not been particularly satisfactory (Worsfold, 2006). If food safety information were more accessible, consumers would be more likely to use it (Worsfold, 2006). In this regard, the Internet presents great possibilities for communicating food safety information to the public. But media’s role has been largely overlooked in existing literature. When the lack of research is combined with consumers’ increasing interest in food safety (Food Safety News, 2016), the need to understand media’s effect is pressing. To further the understanding of media’s role in influencing food safety communication outcome, three progressive studies were conducted. The first study explored consumers’ preferences, motivations, information needs, and information usage. The second study examined consumers’ experience interacting with websites used for food safety communication and mapped website characteristics to users’ perceptions. The third study investigated the relationships among website characteristics, perceptions, efficacies, and behavioral intention, and tested the impact of media on communication outcomes. Results of Study 1 revealed that the Internet was consumers’ preferred media choice for food safety communication. Among Internet-based platforms, websites were most preferred. Media, information, and source characteristics interact in influencing consumers’ experience with the websites and later communication outcome. Thus, it is important to maintain or improve information quality while offering media functionalities that reduces users’ efforts in information seeking. Study 2 showed that consumers go through a two-stage process in food safety communication. First, consumers are informed (usually passively) about an outbreak. Then, after the risks and threat are evaluated, consumers become motivated and actively seek out additional information to make decisions and protect themselves. Additionally, in Study 2, the link between website characteristics and consumers’ efficacy perceptions was established. It was also discovered that the relationships among efficacy components were complex and probably nonlinear. In Study 3, relationships among website characteristics, perceptions towards such characteristics, efficacy perceptions, and behavioral intention were evaluated and tested statistically. It was discovered that website characteristics, through efficacy perceptions, influence consumers’ intention to use the communicated information. The results offered support that media is indeed important and influential and that it works together with information quality to shape consumers’ behavioral intention. More specifically, features on websites that directly related to searchability (e.g. search box and site map) and saliency (specific information about foods and locations involved) were perceived to be most influential and should be specially considered in website design and maintenance

The application of social media for marketing strategies in pharma healthcare

Digital is transforming the way the world does business, and healthcare is no exception. The COVID-19 outbreak has had a significant impact on internet use and accelerated the digital transition worldwide as well as in Portugal. Social media is the fastest communication network among worldwide people. During the outbreak, the usage of social media platforms increased two times more compared with normal days. With increasing health literacy and access to technology, consumers are becoming more informed and proactive towards health issues and selfmedication, 67% of them are researching health problems and symptoms tracking and 81% conduct online research before making a purchase. This change has expanded communication from offline to the internet. Electronic word-of-mouth communication (eWOM), based on social media, brought more variables to marketing communication and became an interesting field for research considering its communication potential. Indeed, several studies have shown the ability to influence interpersonal communications on products or services in the purchase intention of consumers. As so, in recent years, some authors discussed the impact of eWOM on consumer online purchasing decisions; however, the literature is still relatively nascent regarding the Pharmaceutical Industry and the self-medication segment market of Over-the-Counter medicines (OTC). Pharmaceutical companies must be aware of this paradigm change: the patient is an indispensable and active stakeholder in the present and future of healthcare, besides the physician and the payer. Pharma marketing may be moving into a more digitalized space, but there is still room for improvement, especially when it comes to social media there is an unexploited territory for pharma marketers as most pharmaceutical companies are not yet to answer these consumers habits with an effective digital presence. The current research aims to study the application of Social Media platforms for marketing or communication purposes in pharma healthcare in Portugal.digital está a transformar a forma como os negócios se fazem no mundo, e a saúde não é exceção. A pandemia de COVID-19 teve um impacto significativo na utilização da Internet e acelerou a transição digital a nível mundial, incluindo Portugal. Com o aumento da literacia em saúde e o acesso à tecnologia, os consumidores estão a tornar-se mais informados e proativos em relação aos seus cuidados com a saúde e à automedicação, 67% destes pesquisam problemas de saúde e sintomas e 81% realizam pesquisas online antes de fazer uma compra. Esta mudança de comportamento expandiu a comunicação do offline para a Internet. A comunicação electronic word-of-mouth (eWOM), baseada nos media sociais, envolve mais variáveis para a comunicação de marketing; nos últimos anos, alguns autores discutiram o impacto do eWOM nas decisões de compra do consumidor online; entretanto, a literatura ainda é relativamente incipiente no que diz respeito à Indústria Farmacêutica e ao segmento de automedicação do mercado de medicamentos de venda livre (OTC). As empresas farmacêuticas devem estar atentas a esta mudança de paradigma: o paciente é uma parte indispensável e ativa no presente e no futuro da área da saúde, além do médico e do pagador. O marketing farmacêutico está a evoluir para a digitalização, mas ainda há espaço para melhorias, especialmente no âmbito das redes sociais que ainda são um território pouco explorado pelos profissionais de marketing farmacêutico. A maioria das empresas farmacêuticas ainda não se adaptou a estes hábitos de consumo com uma presença digital eficaz. A presente investigação pretende identificar a aplicação de plataformas de redes sociais para efeitos de marketing ou comunicação na área da indústria farmacêutica em Portugal

PROFILING SOCIAL MEDIA TOURISTS USING LITERATURE DURING 2015-2019: CRIMINAL PROFILING METHOD

With the continuous development of mobile commerce and the Internet, social media has deeply penetrated people’s lives and fundamentally changed the way of searching, reading and using travel-related information. With this backdrop, this research studied social media tourists (SMTs) who share or acquire information related to the hospitality and tourism on social media platforms. Based on 271 empirical articles retrieved from major databases and top hospitality and tourism journals in the recent five years from 2015 to 2019, this research developed a profiling framework about SMTs using criminal profiling method. The findings showed the possibility of using the criminal profiling method to analyze SMTs and provided a holistic personal, social-psychological, and behavioral profile of SMTs. Theoretical and practical implications were discussed

Empirical Studies on Online Information Privacy Concerns: Literature Review and an Integrative Framework

In the e-commerce environment, individuals’ concerns for online information privacy play critical roles in determining their intention to use the Internet to provide personal information for services and transactions. Understanding this relationship has important implications for e-commerce. Despite much research in this area, an overarching picture of the relationship between information privacy concerns and the antecedent and consequence factors is yet to be drawn. Based on a review on empirical studies in this area, this research summarizes the conceptualizations of privacy concerns and the antecedents and consequences. An integrative framework is developed to illustrate the relationships between the factors. In this framework, a person’s concern for information privacy regarding a specific e-commerce website is distinguished from his/her concern for information privacy regarding the general e-commerce environment. These two forms of privacy concerns have distinct impacts on a person’s online behavior. Their relationships with multiple antecedent and consequence factors are analyzed

Swaying Individuals’ Privacy Concerns via Amplifying versus Diminishing Counter Argument

Background: Though limited, research has found that individuals\u27 privacy concerns could be swayed by counter argument. This study investigated the swaying influence of amplifying vs. diminishing argument (i.e., counter argument seeking to increase or decrease privacy concerns) on individuals’ privacy concerns and the moderating influences of level of sensitivity and privacy-related knowledge. Method: Data was collected using online survey and respondents were college students enrolled in a Midwestern university. 215 students participated in the survey, resulting in 180 completed responses; two factors (survey competition time and response consistency for reversely-coded items) were used to screen response quality and 90 responses were kept. Data was analyzed using univariate analysis. Results: Results suggest that the swaying influence of counter argument depends on the level of sensitivity—the swaying influence is greater when individuals are presented with amplifying (diminishing) argument for a highly (less) sensitive issue/scenario. In addition, although the swaying influence is smaller for those with high privacy knowledge in general, it is not necessarily easier to sway those with low privacy knowledge. Instead, those with low privacy knowledge are more likely to get stuck or trapped in their existing privacy beliefs when facing privacy argument inconsistent with their existing beliefs, and are more likely to be provoked or stirred up when facing argument reinforcing their existing beliefs. Conclusion: Findings suggest that when processing privacy argument, individuals show confirmation bias and tend to “go with their initial assessments”. This is especially true for those with low privacy knowledge. When facing privacy related argument, individuals with low privacy knowledge behave the opposite of how magnets work—while magnets’ opposite poles attract each other and similar poles repel, individuals with low privacy knowledge embrace argument consistent with their existing beliefs and repel/reject argument inconsistent with their existing beliefs

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Electronic Word of Mouth (Ewom) and the Travel Intention of Social Networkers Post-COVID-19: A Vietnam Case

Purpose: The purpose of this study is to quantitatively determine the impact of electronic word of mouth (eWOM) on the travel intention of Vietnamese social network users. The study proposes solutions to develop online marketing strategies in tourism to quickly restore the tourism industry after the COVID-19 pandemic.   Theoretical framework: This study combines two theoretical models, the Information Acceptance Model (IAM) and the Theory of Reasoned Action (TRA), to explore how electronic Word-of-Mouth (eWOM) impacts travel intentions in Vietnam, particularly in the context of the COVID-19 pandemic. IAM focuses on factors like information quality and credibility, while TRA addresses additional behavioral factors. By integrating these models, the study aims to provide a comprehensive understanding of eWOM's influence on travel intentions among social media users in Vietnam during the pandemic.   Design/Methodology/Approach: The study was conducted in Vietnam. The questionnaire was administered to respondents via an online survey. The results were 262 valid feedback forms conducted in 2023. Linear structural modeling (SEM) was used to measure the relationship between factors in the research model.   Findings: Research results show that all factors have a positive impact on travel intention through other factors, or will directly impact travel intention of social network users in Vietnam.   Research,  Practical  &  Social implications: It is critical to focus on building marketing channels that support electronic word-of-mouth (eWOM) in order to successfully promote trip ambitions. The Tourism Office has adopted digital marketing as a cutting-edge strategy for promoting the region's tourism potential (Burhan, 2023). Furthermore, because travel intentions are positively related to information acceptance, these channels must prioritize improving the quality and dependability of eWOM information. Furthermore, channel managers should keep a careful eye on customers' opinions regarding eWOM-related concerns. Finally, administrators should create unique, context-based solutions that might increase travel intentions among social network members while taking Vietnam's cultural context into consideration. This proactive strategy enables rapid revisions and customized solutions to successfully engage with the Vietnamese audience.   Originality/Value: The unique contribution of this paper lies in its innovative introduction of a modified theoretical model of rational action. This model aims to elucidate factors influencing tourist travel behavior in a way that has not been explored in previous research. Specifically, it amalgamates elements from three existing models (TRA, IAM, and TPB) and introduces an additional eWOM factor to enhance the understanding of behavioral intentions. This novel factor, devised by the authors in their research model, holds particular relevance for a country like Vietnam, characterized by its developing technological landscape and strong traditional culture. This novelty significantly enhances our ability to analyze the impact of eWOM on travel intentions among social media users in Vietnam, especially during the prolonged effects of the COVID-19 pandemic
