The effect of personality traits on over-the-top service use and binge-watching.

With the freedom to consume content on preferred devices at any time as long as there is an Internet connection, the growing demand for over-the-top (OTT) services is evident. In conjunction with the rise of OTT services, binge-watching has become a prevalent behavior. In this research, we explore whether personality traits including the Big Five and need for cognition wield an effect on OTT use and binge-watching. We used a large, diverse, population representative sample from South Korea to investigate this topic. Results indicated that openness to experience and need for cognition were positively related to OTT use. Openness to experience, emotional stability, conscientiousness, and need for cognition had a negative association with binge-watching. When the sample was split by OTT frequency, the binge-watching effects were obtained exclusively for daily OTT users. For non-daily OTT users, most of the personality traits did not exert an effect on binge-watching. Implications of the current findings as well as limitations and future research are presented.

Consumers' Evaluation of Web-Based Health Information Quality: Meta-analysis.

BACKGROUND: The internet has become a major source of health information for general consumers. Web-based health information quality varies widely across websites and applications. It is critical to understand the factors that shape consumers' evaluation of web-based health information quality and the role that it plays in their appraisal and use of health information and information systems. OBJECTIVE: This paper aimed to identify the antecedents and consequences of consumers' evaluation of web-based health information quality as a means to consolidate the related research stream and to inform future studies on web-based health information quality. METHODS: We systematically searched 10 databases, examined reference lists, and conducted manual searches. Empirical studies that investigated consumers' evaluation of web-based health information quality, credibility, or trust and their respective relationships with antecedents or consequences were included. RESULTS: We included 147 studies reported in 136 papers in the analysis. Among the antecedents of web-based health information quality, system navigability (ρ=0.56), aesthetics (ρ=0.49), and ease of understanding (ρ=0.49) had the strongest relationships with web-based health information quality. The strongest consequences of web-based health information quality were consumers' intentions to use health information systems (ρ=0.58) and satisfaction with health information (ρ=0.46). Web-based health information quality relationships were moderated by numerous cultural dimensions, research designs, and publication moderators. CONCLUSIONS: Consumers largely rely on peripheral cues and less on cues that require more information processing (eg, content comprehensiveness) to determine web-based health information quality. Surprisingly, the relationships between individual differences and web-based health information quality are trivial. Web-based health information quality has stronger effects on cognitive appraisals and behavioral intentions than on behavior. Despite efforts to include various moderators, a substantial amount of variance is still unexplained, indicating a need to study additional moderators. This meta-analysis provides broad and consistent evidence for web-based health information quality relationships that have been fractured and incongruent in empirical studies.

Trust in health information websites: A systematic literature review on the antecedents of trust.

Health websites are important sources of information for consumers. In choosing websites, trust in websites largely determines which website to access and how to best utilize the information. Thus, it is critical to understand why consumers trust certain websites and distrust others. A systematic literature review was conducted with the goal of identifying the antecedents of trust in health information websites. After four rounds of screening process, 20 articles between 2000 and 2013 were harvested. Factors that determine trust are classified into individual difference antecedents, website-related antecedents, and consumer-to-website interaction-related antecedents. The most frequently studied antecedents were socio-demographics, information quality, appearance, and perceived reputation of the website. Each antecedent of trust are discussed in detail and future research directions are proposed.

On the relationship between coefficient alpha and composite reliability.

Cronbach's coefficient alpha is the most widely used estimator of the reliability of tests and scales. However, it has been criticized as being a lower bound and hence underestimating true reliability. A popular alternative to coefficient alpha is composite reliability, which is usually calculated in conjunction with structural equation modeling. A quantitative analysis of 2,524 pairs of coefficient alpha and composite reliability values derived from empirical investigations revealed that although the average composite reliability value (.86) exceeded the average corresponding coefficient alpha value (.84), the difference was relatively inconsequential for practical applications such as meta-analysis.
