Seeking Information About Climate Change: Effects of Media Use in an Extended PRISM

This study replicates and extends the planned risk information seeking model (PRISM) in the context of impersonal risk by incorporating media use as an antecedent of risk information seeking intention. Results indicate that the model applies equally well to Singaporeans’ climate change information seeking intention as it does in the context of personal health information, suggesting that the model is generalizable across different risk and cultural contexts. Findings suggest that media use is an important source of perceived knowledge and, indirectly, sufficiency threshold, which clarifies the role of actual information seeking in risk perceptions and future information seeking.

Explicating problematic social network sites use: A review of concepts, theoretical frameworks, and future directions for communication theorizing

The prevalence of social network sites (SNSs) has sparked a growing interest in understanding the development of problematic SNSs use among adolescents. Yet, this nascent area of research is marked by some deficiencies in existing theoretical paradigms. This article seeks to review the state of research in problematic SNSs use—broadly with a specific focus on adolescents—and identify key areas of research for future scholarly work. First, we summarize the historical and recent developments of media addiction and problematic SNSs use research. Second, we discuss the theoretical perspectives that contribute to our understanding of the problematic SNSs use phenomenon and identify the weaknesses of these frameworks. Third, we propose that communication scholars should strive for theoretical integration and examine the impact of microsystem (e.g. parents and peers) and macrosystem (e.g. surveillance culture) on the development of problematic SNSs among adolescents. Directions for future theoretical and methodological approaches are suggested.

Social Network Sites, Friends, and Celebrities: The Roles of Social Comparison and Celebrity Involvement in Adolescents’ Body Image Dissatisfaction

This study applies the social comparison theory to examine the effects of adolescents’ engagement in comparison with friends and celebrities on social network sites (SNSs) on (a) their body image dissatisfaction (BID) and (b) their drive to be thin (DT) or muscular (DM). The study also examines celebrity involvement as an antecedent of the outcome variables. Data were collected through a survey of 1,059 adolescents in Singapore. Regression analyses indicate that SNSs use was related to adolescents’ BID. Specifically, social comparison with friends on SNSs was significantly associated with adolescents’ BID, DT, and DM. Gender differences were also observed—social comparison with celebrities was significantly associated with BID and DT among female adolescents. Celebrity involvement was significantly associated with male BID. Theoretical and practical implications were discussed.

The perceived familiarity gap hypothesis: examining how media attention and reflective integration relate to perceived familiarity with nanotechnology in Singapore

Public level of familiarity with nanotechnology partly determines their acceptance or rejection of the technology. This study examines the differential influence of public attention to science news in the media and reflective integration on perceived familiarity with nanotechnology among people in the higher and lower socioeconomic status (SES) groups in Singapore. Significant three-way interactions among education, science news attention, and reflective integration variables were found. Attention to television science news narrowed the level of perceived familiarity with nanotechnology between the higher and lower SES groups for those who engaged in high elaborative processing. Science newspaper attention, on the other hand, widened the familiarity gap between the higher and lower SES groups among those who engaged in high elaborative processing. Two-way interaction among education and elaborative processing were found—elaborative processing closed the familiarity gap between higher and lower SES groups. Theoretical and practical implications were discussed.

Extending the Cognitive Mediation Model: Examining Factors Associated With Perceived Familiarity and Factual Knowledge of Nanotechnology

This research—a pilot study on the cognitive mediation model (CMM) in Singapore—seeks to revisit and test the applicability of an extended CMM in the context of nanotechnology by examining perceived familiarity as a separate outcome variable in addition to factual knowledge. A cross-sectional survey was administered to a nationally representative sample of 719 adult Singaporeans. Results demonstrated partial support for the hypothesized CMM. First, elaboration was positively associated with both factual knowledge and perceived familiarity, whereas interpersonal discussions about science was associated only with familiarity. Results also showed differential relationships between attention to media platforms (traditional vs. new media) and reflective integration (composed of elaborative processing and interpersonal discussion); whereas attention to science reporting in newspapers and science television programs were associated with elaboration, media attention across all platforms were associated with interpersonal discussions. Theoretical and practical implications are discussed.

The Augmented Cognitive Mediation Model: Examining Antecedents of Factual and Structural Breast Cancer Knowledge Among Singaporean Women

As knowledge acquisition is an important component of health communication research, this study examines factors associated with Singaporean women’s breast cancer knowledge using an augmented cognitive mediation model. We conducted a nationally representative study that surveyed 802 women between the ages of 30 and 70 using random-digit dialing. The results supported the augmented cognitive mediation model, which proposes the inclusion of risk perception as a motivator of health information seeking and structural knowledge as an additional knowledge dimension. There was adequate support for the hypothesized paths in the model. Risk perception was positively associated with attention to newspaper, television, Internet, and interpersonal communication. Attention to the three media channels was associated with interpersonal communication, but only newspaper and television attention were associated with elaboration. Interpersonal communication was positively associated with structural knowledge, whereas elaboration was associated with both factual and structural knowledge. Differential indirect effects between media attention and knowledge dimensions via interpersonal communication and elaboration were found. Theoretical and practical implications are discussed.

For Fit’s Sake: A Norms-Based Approach to Healthy Behaviors Through Influence of Presumed Media Influence

ABSTRACT Based on the influence of presumed media influence (IPMI) model as the theoretical framework, this study examines how injunctive norms and personal norms mediate the influence of healthy lifestyle media messages on public intentions to engage in two types of healthy lifestyle behaviors—physical activity and healthy diet. Nationally representative data collected from 1,055 adults in Singapore demonstrate partial support for the key hypotheses that make up the extended IPMI model, highlighting the importance of a norms-based approach in health communication. Our results indicate that perceived media influence on others indirectly shaped public intentions to engage in healthy lifestyle behaviors through personal norms and attitude, providing partial theoretical support for the extended IPMI model. Practical implications for health communicators in designing health campaigns media messages to motivate the public to engage in healthy lifestyle are discussed.

Staying abreast of breast cancer: examining how communication and motivation relate to Singaporean women's breast cancer knowledge

Numerous health communication studies have highlighted the importance of factual knowledge as an antecedent to health behavior, but few have explored other dimensions of health knowledge, such as structural knowledge. This study seeks to fill this gap by investigating conceptual differences between these two kinds of knowledge in the context of breast cancer in Singapore, and find out how communication and motivational factors are related to them. Using a nationally representative random-digit-dialing survey of women aged 30–70 (N = 802), results showed that interpersonal communication and elaboration were associated with both knowledge types. Attention to online health news and the level of risk perception were positively associated with structural knowledge but not factual knowledge. Theoretical and practical implications for health communication were discussed.

Communication and knowledge as motivators: understanding Singaporean women’s perceived risks of breast cancer and intentions to engage in preventive measures

As breast cancer is the most prevalent cancer among women in Singapore, encouraging them to engage in preventive measures becomes increasingly important. This study aims to take a closer look at the influence of attention to media, interpersonal communication, news elaboration, and knowledge on women’s (aged between 30 and 70) perceived risks of breast cancer and their intentions to engage in preventive measures in Singapore. Attention to media, frequency of interpersonal communication, fatalistic belief, and knowledge structure density were found to be associated with risk perception of breast cancer among Singaporean women. Findings also showed that frequency of interpersonal communication, risk perception, elaboration, and factual knowledge were positively associated with women’s intentions to take up preventive measures such as breast self-examination, clinical breast examination, and mammography. Implications for theory and practice were discussed.

Are Photographs Worth More Than a Thousand Words? Examining the Effects of Photographic–Textual and Textual-Only Frames on Public Attitude Toward Nuclear Energy and Nanotechnology

This study examines the impact of photographic–textual and risk–benefit frames on the level of visual attention, risk perception, and public support for nuclear energy and nanotechnology in Singapore. Using a 2 (photographic–textual vs. textual-only frames) × 2 (risk vs. benefit frames) × 2 (nuclear energy vs. nanotechnology) between-subject design with eye-tracking data, the results showed that photographic–textual frames elicited more attention and did have partial amplification effect. However, this was observable only in the context of nuclear energy, where public support was lowest when participants were exposed to risk frames accompanied by photographs. Implications for theory and practice were discussed.
