The purpose of this paper is to investigate the direct effects of eHealth literacy, perceived competence, perceived electronic word-of-mouth (eWOM) credibility and price perception on consumers' willingness to purchase online mental health services. This study also examines the mediating role of perceived information quality on the eHealth literacy-consumers' willingness to purchase online mental health services relationship and the moderating roles of perceived eWOM credibility and price perception on the perceived competence-consumers' willingness to purchase online mental health services relationship.

Based on an extensive literature review, a conceptual model was developed. The research design was cross-sectional. A total of 400 respondents participated in the self-administered survey. After discarding some questionnaires due to incompleteness and lack of variance, a total of 367 responses was used in final data analysis. Partial least square structural equation modeling (PLS-SEM) was used to test the proposed model.

eHealth literacy, perceived competence, perceived eWOM credibility and price perception were found to have significant positive direct effects on consumers' willingness to purchase online mental health services. Perceived information quality was found to have a significant partial mediating effect on the eHealth literacy-consumers' willingness to purchase online mental health services relationship. Both perceived eWOM credibility and price perception were found to have significant positive moderating effects on the perceived competence-consumers' willingness to purchase online mental health services relationship.

Studies concerning online mental health services from a marketing or business perspective is almost non-existent. Therefore, this study contributes to the scarce literature in that context. This is the first study that has investigated how eHealth literacy, perceived information quality, perceived competence, perceived eWOM credibility and price perception influence consumers' willingness to purchase online mental health services.

Policymakers push online health services delivery, relying on consumers to independently engage with online services. Yet, a growing cluster of vulnerable patients do not engage with or disengage from these innovative services. There is a need to understand how to resolve the tension between the push of online health service provision and unengagement by a contingent of health-care consumers. Thus, this study aims to explore the issue of digital unengagement (DU) (i.e. the active or passive choice to engage or disengage) with online health services to better inform service design aligned to actual consumer need.

Adopting a survey methodology, a group of 486 health services consumers with a self-declared (acute or chronic) condition were identified. Of this group, 110 consumers were classified as digitally unengaged and invited to write open-ended narratives about their unengagement with online health services. As a robustness check, these drivers were contrasted with the drivers identified by a group of digitally engaged consumers with a self-declared condition (n = 376).

DU is conceptualized, and four levels of DU drivers are identified. These levels represent families of interrelated drivers that in combination shape DU: subjective incompatibility (misalignment of online services with need, lifestyle and alternative services); enactment vulnerability (personal vulnerabilities around control, comprehension and emotional management of online services); sharing essentiality (centrality of face-to-face co-creation opportunities plus conflicting social dependencies); and strategic scepticism (scepticism of the strategic value of online services). Identified challenges at each level are the mechanisms through which drivers impact on DU. These DU drivers are distinct from those of the digitally engaged group.

Adding to a nascent but growing literature on consumer unengagement, and complementing the engagement literature, the authors conceptualize DU, positioning it as distinct from, not simply a lack of, consumer engagement. The authors explore the drivers of DU to provide insight into how DU occurs. Encapsulating the dynamic nature of DU, these drivers map the building blocks that could help to address the issue of aligning the push of online service provision with the pull from consumers.

This paper offers insights on how to encourage consumers to engage with online health services by uncovering the drivers of DU that, typically, are hidden from service designers and providers impacting provision and uptake.

There is a concern that there will be an unintentional disenfranchisement of vulnerable segments of society with a generic policy emphasis on pushing online services. The paper sheds light on the unforeseen personal and social issues that lead to disenfranchisement by giving voice to digitally unengaged consumers with online health services.

Offering a novel view from a hard-to-reach digitally unengaged group, the conceptualization of DU, identified drivers and challenges inform policymakers and practitioners on how to facilitate online health service (re)engagement and prevent marginalization of segments of society.

The purpose of this study is to explain predictors that discriminate users’ preferences for online health services, focusing on a downtown area in a developing country.

Drawing on rational choice theory (RCT), the authors test a model that links the frequency of online health service usage to access-activators and access-inhibitors. Multivariate analysis of variance (MANOVA) and the discriminant analysis model were used to analyze data from a sample of 215 internet users.

Results confirm the significance of responsiveness, user’s attitude, accessibility and perceived ease of use, indicating their discriminating role in the usage of online health services.

The study demonstrates the relevance of RCT in measuring perceived online health service quality in an emerging context. Future research should consider the influence of electronic health (eHealth) literacy, norms and trustworthiness to increase the generalizability of the findings.

The findings of this study can help enhance the eHealth service quality by encouraging service providers to improve the interactivity and ease of use of their platforms, thus delivering value to both consumers and firms and improving the well-being of the society at large.

Few existing studies draw attention to access-activators and access-inhibitors to predict users’ preferences for online health services. This study shows the applicability of RCT in preparing the instrumental dimensions of online health service quality.

The purpose of this paper is to help understand consumer acceptance of online health information services by integrating the health belief model and extended valence framework.

A laboratory-based, experimental-scenarios research design is used to collect data, and the structural equation modeling technique is used to test the research model.

The model explains 47.6 percent of the variance in intentions to use online health information services. Trust appeared to have the strongest effect on acceptance. Perceived risk also had a significant impact on acceptance. Furthermore, health belief variables are confirmed as important factors for consumer acceptance. Self-efficacy was found to moderate the effect of perceived severity on acceptance.

This study helped identify the relative salience of the health belief model and extended valence framework in consumer acceptance of online health information services.

This study can help practitioners better understand the development of trust and the profiles of consumers who may browse their sites. When online health service providers promote their information to encourage potential online health information seekers, they should use countermeasures against risk perceptions.

This study attempted to extend the valence framework to the non-commercial service context. Moreover, health beliefs and the valence framework are two fundamental aspects that health information seekers consider when making decisions about online health services.

Examines statistically the public's use and attitudes towards interactive and personal health services via an online questionnaire survey and enhances these data with an expert assessment of a number of consumer health sites and their services. Over a period of three weeks more than 1,300 people responded to an online questionnaire produced by The British Life and Internet Project. Of the respondents, 81 per cent were British. The likely potential uptake figure for support group participation among Internet health users is about 20 per cent while around 11 to 13 per cent will go online to describe a medical condition. Those in poor heath were approximately ten to 13 times more likely to have participated in an online support group. Those aged over 65 were four times as likely to e‐mail their doctor. More positive health outcomes were associated with those respondents that participated in online support groups and the least number of health outcomes were associated with those people that maintained e‐mail contact with a doctor or surgery.

Doctor–medical institution collaboration (DMIC) services are an emerging service mode in focal online health communities (OHCs). This new service mode is anticipated to affect user satisfaction and doctors' engagement behaviors. However, whether and how DMIC occurs is still ambiguous because the topic is rarely examined. To bridge this gap, this study explores doctors' participation in DMIC services and its effects on their online performance, as well as its effect on patients' evaluation of them on OHC platforms.

The authors propose hypotheses based on structural holes theory. A unique dataset obtained from one of the most popular OHCs in China is used to test the hypotheses, and difference-in-differences estimation is adopted to test the causality of the relationship.

The results demonstrate that providing DMIC services improves doctors' online consultation performance and patients' evaluations of them but has no significant effect on doctors' knowledge-sharing performance on OHC platforms. Doctors' knowledge-sharing performance and consultation performance mediate the relationship between participation in DMIC services and patients' evaluation of doctors. Regarding doctors' participation in DMIC services, its impact on doctors' consultation performance and patients' evaluation of them is weaker for doctors with higher professional titles than for doctors with lower professional titles.

The findings clarify the value creation mechanisms of online collaboration between doctors and medical institutions and thereafter facilitate doctors' participation in DMIC services and enhance the sustainable development of OHCs.

This study aims to investigate the external and internal stimuli, which affect the organismic experiences of the users and thereby influence their response in terms of behavioral intention toward the use of online doctor consultation platforms.

The study operationalized the stimulus–organism–response framework for the research model and surveyed 357 users in India who had experienced online doctor consultation platforms. The analysis has been done using the structural equation modeling approach.

The authors’ main results indicate the following key points. One, perceived usefulness, social influence, health anxiety, offline consultation habit and perceived technology usage risk are significant predictors of perceived value. In contrast, perceived ubiquity is identified to be an insignificant predictor of perceived value. Second, social influence and perceived technology usage risk have significant influence on trust. However, perceived usefulness is not a significant predictor of trust.

This study contributes to the theory by integrating technology-oriented factors with behavioral attributes for determining the behavioral intention of users toward the online doctor consultation platforms.

The managerial contributions of this study involve highlighting those technology-oriented and behavioral elements, which can be targeted to attract more users toward these platforms.

This is an original study that has looked beyond the role of technology-oriented factors in influencing the perceived value and trust elements while investigating the behavioral intention among the users toward the online doctor consultation platforms.

The advancement of technologies has made it possible for health-care organizations to provide convenient online services that enable people to manage their health conditions. Although many studies have investigated the adoption and benefits of e-health services, there has been little focus on health-oriented behaviors after adoption, particularly in relation to service quality and user satisfaction.

This paper is based on the SOR model and service quality theories to investigate behavioral responses, including word-of-mouth, intention to use and intention to act. The authors use a partial least squares structural equation modeling analysis with 194 participants and the diabetes risk test survey in Finland.

The results show that people are willing to engage in health self-management behaviors if they intend to use the e-health service and are satisfied with it. User satisfaction can be enhanced by improving the visual appeal of the website presentation, the quality of the presented information, as well as the usability of the website, all as components of e-health services.

The authors contribute by creating a construct “intention to act,” referring to health-oriented behaviors resulting from e-health service use. In addition, this study is among the first to apply the SOR model to investigate how user satisfaction leads to intention to use, intention to act and word-of-mouth.

This study aims to study the mechanisms and conditions of users' intention to continue to use online health platforms from an information technology (IT) affordance perspective.

b This research proposes that a critical affordance effect on an online health platform, users' intention to continue the use of the platform, is affected by five platform affordances via two actualized affordances (i.e. perceived benefits (PBs) and online engagement (OE)). Perceived health threat moderates the effect generated by affordance actualization. A dataset involving 409 users from the “Ping An Health” platform was collected through an online survey and analyzed to validate the research hypotheses.

The data analysis results confirm that the proposed online health platform affordances affect users' PBs and OE, which influence users' intentions to continue using the platform. Perceived threats (perceived vulnerability (PVU) and perceived severity (PSE)) moderate the relationship between PBs and continuance intention (CI) and between OE and CI.

The research provides important recommendations for online health platform designers to develop IT affordances that can support users' needs for healthcare services.

Limited studies investigated why users continue participating in online diagnosis and treatment. This study provides a new perspective to expand the affordance framework by combining technology features and user health behavior. The study also emphasizes the importance of perceived threats in IT use.
