Effects of argument quality, source credibility and self-reported diabetes knowledge on message attitudes: an experiment using diabetes related messages

What Influences Audience Susceptibility to Fake Health News: An Experimental Study Using a Dual Model of Information Processing in Credibility Assessment

This experimental study investigates the effects of several heuristic cues and systematic factors on users' misinformation susceptibility in the context of health news. Specifically, it examines whether author credentials, writing style, and verification check flagging influence participants' intent to follow article behavioral recommendations provided by the article, perceived article credibility, and sharing intent. Findings suggest that users rely only on verification checks (passing/failing) in assessing information credibility. Of the two antecedents to systematic processing, social media self-efficacy moderates the links between verification and participants' susceptibility. Theoretical and practical implications are discussed.

Information adoption behavior in online healthcare communities from the perspective of personality traits

Improving standards of living have resulted in an increased focus on health and image management. In a context where the quality of healthcare information is unguaranteed, the adoption behavior intention of online health information varies greatly. Hence, it is essential to take effective measures to guide community users to obtain high-quality information on demand. From the perspective of personality traits, the present study analyzed the influencing factors and mechanisms of adoption behavior intention of healthcare information in online healthcare communities as well as the moderating effects of social support. A quantitative analysis of 380 respondents revealed positive associations between five personality dimensions and the adoption behavior intention of healthcare information–extraversion, agreeableness, conscientiousness, neuroticism, and openness. The study also determined that health concerns and health-related self-efficacy played a mediating role across various degrees between the conscientiousness and adoption behavior intention of healthcare information. As an important contextual factor influencing health outcomes, social support is common in online healthcare communities. The study examined the effect of the interaction between inner traits and social support on adoption behavior intention. Perceived self-esteem support strengthened the indirect effect of conscientiousness on adoption behavior intention mediated by health concerns and health-related self-efficacy. Additionally, the impact of high neuroticism interacted with low levels of perceived self-esteem support on adoption behavior intention was significant. Likewise, emotional supportive information did not help in facilitating the adoption behavior intention in terms of all five personality traits and negatively influence the adoption behavior intention for individuals high in neuroticism and agreeableness. The possible explanation for the results was discussed with the intention of understanding the psychological mechanisms which guide adoption behavior intention.

Understanding Health Empowerment From the Perspective of Information Processing: Questionnaire Study

Background

Massive, easily accessible online health information empowers users to cope with health problems better. Most patients search for relevant online health information before seeing a doctor to alleviate information asymmetry. However, the mechanism of how online health information affects health empowerment is still unclear.

Objective

To study how online health information processing affects health empowerment.

Methods

We conducted a cross-sectional questionnaire study that included 343 samples from participants who had searched online health information before the consultation. Respondents' perceptions of online information cues, benefits, health literacy, and health empowerment were assessed.

Results

Perceived argument quality and perceived source credibility have significant and positive effects on perceived information benefits, but only perceived argument quality has a significant effect on perceived decision-making benefits. Two types of perceived benefits, in turn, affect health empowerment. The effects of perceived argument quality on perceived informational benefits and perceived decision-making benefits on health empowerment are significantly stronger for the high health literacy group than the low health literacy group (t₂₆₉=7.156, P<.001; t₂₆₉=23.240, P<.001). While, the effects of perceived source credibility on perceived informational benefits and perceived informational benefits on health empowerment are significantly weaker for the high health literacy group than the low health literacy group (t₂₆₉=–10.497, P<.001; t₂₆₉=–6.344, P<.001). The effect of perceived argument quality on perceived informational benefits shows no significant difference between high and low health literacy groups.

Conclusions

 In the context of online health information, perceived information benefits and perceived decision-making benefits are the antecedents of health empowerment, which in turn will be affected by perceived argument quality and perceived source credibility. Health literacy plays a moderating role in the relationship of some variables. To maximize health empowerment, online health information providers should strengthen information quality and provide differentiated information services based on users' health literacy.

Using a computer-tailored COPD screening assessment to promote advice-seeking behaviors

Background

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity and mortality, despite evidence there is a high proportion of underdiagnosis. Online screening assessments are low-cost solutions to identify high-risk adults who may benefit from confirmatory screening (ie, spirometry test). Little evidence exists to support whether high-risk adults seek advice after completing COPD screening assessments and from whom. The purpose of this study is to examine how the perceived quality of an online screening assessment influences high-risk adults to seek advice from a healthcare provider or other online resources.

Methods

Adults without a prior COPD diagnosis (N = 199) completed an online survey that included a computer-tailored assessment programmed with the clinically validated COPD Population Screener (COPD-PS).

Results

An elevated COPD risk score was associated with expectations to talk with a healthcare provider (P < 0.05) or go on the Internet (P < 0.05) to get advice, controlling for statistically significant covariates. Positive perceptions about the quality of the risk score was associated with strengthened expectations to speak with a healthcare provider, but only among high-risk adults (P < 0.01).

Conclusions

Results of this study support the use of computer-tailored screening assessments as a scalable solution to encourage high-risk adults to learn more about COPD. Strengthened perceptions about the quality of an online COPD screening assessment increased the likelihood that high-risk adults will speak with their healthcare provider about the condition. Implications are discussed for leveraging telehealth solutions, such as conversational agents (ie, chatbots), to disseminate COPD screening assessments and alleviate its underdiagnosis.

Research on consumers' health information consultation patterns

Purpose

This paper aims to identify consumers' health information consultation patterns by analyzing information sources to better understand consumers' health information needs and behavior in the context of multisource health information.

Design/methodology/approach

Haodaifu Online, an online health consultation (OHC) website in China, was used as a research data source, and 20,000 consultation cases were collected from the website with Python. After screening and cleaning, 1,601 consultation cases were included in this study. A content analysis-based mixed-methods research approach was applied to analyze these cases.

Findings

The results indicate that with the participation of OHC, there are 15 patterns of consumer health information consultation. Besides OHC, health information sources reported by consumers included medical institutions family/friends and the Internet. Consumers consult on a wide range of health issues including surgical conditions obstetrical and gynecological conditions and other 20 subjects. Consumers have multiple information needs when using OHC: getting prescriptions, diagnosing diseases, making appointments, understanding illnesses, confirming diagnoses and reviewing costs. Through further analysis it was found that consumers’ health information consultation patterns were also significantly different in health issues and health information needs.

Originality/value

This study broadens one’s understanding of consumer health information behavior, which contributes to the field of health information behavior, and also provides insight for OHC stakeholders to improve their services.

Choosing not to follow rules that will reduce the spread of COVID-19

In response to the COVID-19 pandemic, many authorities have implemented public health measures that place restrictions on individuals. Understanding how individuals respond to these new rules, particularly whether they are likely to follow or break them, is extremely important. Relational frame theory offers unique insights into rule-governed behavior, allowing researchers to develop functional-analytic interpretations of why a listener may understand a rule, have the required response established in their behavioral repertoire, and still choose not to follow the rule. Drawing from research on rule-following in accordance with relational frame theory and cognitive neuroscience, social psychology, and health literature, this paper presents reasons why a rule may be understood but not followed, identifying important considerations for implementing public health measures to reduce the spread of COVID-19. Specifically, rule-givers should attend to their credibility, authority and ability to mediate consequences, rule plausibility, establishing adequate motivative augmental control, whether the behavior specified in the rule opposes habits, and whether the message incites counterpliance.

An epistemological assessment of learning nutritional information with augmented reality

Purpose

This study aims to investigate whether epistemological assessment is a suitable approach to evaluate students’ learning of dietary knowledge via the use of an augmented reality (AR) information system. Students’ perceived dietary knowledge was compared before and after learning with the AR system. Two major questions were addressed: Did students improve their understanding of dietary knowledge after the use of AR information system? Did students gain more appropriate understanding of dietary knowledge after the use of AR information system?

Design/methodology/approach

A mixed-methods approach was used in the study. The mobile AR system was used among 65 volunteered non-nutrition-major college students recruited in campus. For promoting epistemological development of personal dietary knowledge, students practiced with life experiences to access daily dietary information. Pre- and post-tests of students’ understanding of dietary knowledge were compared. Interviews with 20 students were used for gathering in-depth research data to analyse students’ epistemological understanding of dietary knowledge.

Findings

The epistemological assessment indicated an improvement in learning after the use of the AR system. Students gradually gained awareness of dietary knowledge and changed their perceptions of their dietary behaviours. Epistemological approaches to the analysis of students’ conceptual change in dietary knowledge revealed a significant increase in the mean nutritional concepts (p< 0.01) and a decrease in their mean misconceptions (p< 0.001) after learning via the mobile nutrition monitoring system. Learning assessment of 65 students also indicated a significant increase from the post-test after learning with the system (p< 0.0001).

Research limitations/implications

This study might have its limitations, as it only assessed learning using a pretest-posttest design for a specific learning context over a short period of learning time. The use of interviews based on the epistemological approach might have its limitations in the interpretations of the phenomenon. Future implementations can also be extended to different populations to promote self-monitoring dietary behaviours.

Originality/value

The findings of this study will contribute to the application of AR in learning about dietary knowledge. The research involving in-depth observation of students’ learning relevant to personal nutritional information needs via mobile AR might provide potential contributions to dietitian professionals and health education.
