Evaluating information skills training in health libraries: a systematic review

Introduction: Systematic reviews have shown that there is limited evidence to demonstrate that the information literacy training health librarians provide is effective in improving clinicians’ information skills or has an impact on patient care. Studies lack measures which demonstrate validity and reliability in evaluating the impact of training. Aim: To determine what measures have been used; the extent to which they are valid and reliable; to provide guidance for health librarians who wish to evaluate the impact of their information skills training. Methods: Data sources: Systematic review methodology involved searching seven databases, and personal files. Study selection: Studies were included if they were about information skills training, used an objective measure to assess outcomes, and occurred in a health setting. Results: Fifty‐four studies were included in the review. Most outcome measures used in the studies were not tested for the key criteria of validity and reliability. Three tested for validity and reliability are described in more detail. Conclusions: Selecting an appropriate measure to evaluate the impact of training is a key factor in carrying out any evaluation. This systematic review provides guidance to health librarians by highlighting measures used in various circumstances, and those that demonstrate validity and reliability.

Consumer health information seeking in social media: a literature review

Objective

The objective of this literature review was to summarise current research regarding how consumers seek health‐related information from social media. Primarily, we hope to reveal characteristics of existing studies investigating the health topics that consumers have discussed in social media, ascertaining the roles social media have played in consumers’ information‐seeking processes and discussing the potential benefits and concerns of accessing consumer health information in social media.

Methods

The Web of Science Core Collection database was searched for existing literature on consumer health information seeking in social media. The search returned 214 articles, of which 21 met the eligibility criteria following review of full‐text documents.

Conclusion

Between 2011 and 2016, twenty‐one studies published explored various topics related to consumer information seeking in social media. These ranged from online discussions on specific diseases (e.g. diabetes) to public health concerns (e.g. pesticide residues). Consumers’ information needs vary depending on the health issues of interest. Benefits of health seeking on social media, in addition to filling a need for health information, include the social and emotional support health consumers gain from peer‐to‐peer interactions. These benefits, however, are tempered by concerns of information quality and authority and lead to decreased consumer engagement.     

Young adults and everyday-life information: The role of news media

There is a paucity of research examining the everyday-life information seeking of young people, especially investigating the role that the news media has in providing information to young people for use in their everyday lives. A qualitative, interpretivist approach is adopted, involving 34 students, ages 18 to 25, from an Australian university. First, 20 students were interviewed about their news seeking (including topics and sources). Then 14 students participated in verbal protocol analysis, which involved a series of tasks concerning online and print newspapers. Lastly, students were interviewed about how they sought everyday-life information and whether they thought that they had incidentally acquired or encountered information on everyday-life topics in online or print newspapers in the recent past. Findings indicated that, contrary to expectations, traditional print media still played a role for young people, and social media were perceived as important for communication with friends, rather than for news gathering. Purposeful information seeking was more likely to occur online, but both print and online newspapers retained an incidental role in providing information to students for their everyday lives. Participants used a range of media to suit their particular needs and purposes. Thus, access to a wide variety of sources is important for everyday-life information seeking (ELIS) by young people.     

Measuring Exposure to Media with Antisocial and Prosocial Content: An Extended Version of the Content-based Media Exposure Scale (C-ME2)

The present research developed a measure for exposure to both antisocial and prosocial media content by revising and extending a previous Content-based Media Exposure Scale (C-ME). The validity and reliability of the C-ME2 was tested in two independent samples (N = 678), among young adults (Study 1) and adolescents (Study 2). Results of Confirmatory Factor Analyses showed good fit, in both studies, for both antisocial and prosocial dimensions of media content, and for both males and females. Furthermore, the C-ME2 explains unique variance beyond previous measures of violent and general media exposure. Evidence is presented of reliability, discriminant and predictive validity of the C-ME2, measuring both frequency and exposure to specific content of media. The C-ME2 covers all media platforms, is easy to use in all research designs, and allows for standardization and systematic comparisons across studies.     

Measuring Exposure to Direct-to-Consumer Advertising: A Validation Study in the Context of Cancer-Related Treatment Advertising

This research examines two recurrent conceptual issues of measuring media exposure in survey research—content specificity of survey items and whether exemplars should be provided to aid recall. In two population-based surveys, we evaluated three candidate measures of cancer patients’ self-reported exposure to cancer-related direct-to-consumer advertising (CR-DTCA); these measures varied in content specificity and provision of ad exemplars. All three measures performed equally well in terms of internal consistency, convergent, nomological, and discriminant validity. Increased content specificity or ad exemplars did not improve performance of the exposure measures. Participants were able to extrapolate from ad exemplars to report their exposure to broad categories of CR-DTCA. The briefest of the three measures posed the lowest level of survey costs and was deployed successfully for mailed and internet-based survey administration. We discussed future directions for application of these findings in DTCA research for other illness and for media exposure research more generally.

Preparing public librarians for consumer health information service: A nationwide study

A nationwide survey study was conducted to gain understanding as to how to prepare public librarians for consumer health information service. Findings indicate that the popular health information needs encountered by public librarians cover a wide variety of topics, including the human body, a medical/health condition, a disease, a medical concept, and fitness/diet/nutrition. The top two challenges faced by public librarians when providing consumer health information service are difficulty in interpreting patrons' questions and lack of knowledge about available and trusted/appropriate medical/health information sources. Public librarians wish to receive training on a number of topics that could help address the challenges they face, and the most favorable training format for them, among all the options provided in the survey, is the self-paced online tutorial. This study constitutes the basis for establishing training requirements and developing training programs to meet the needs of public librarians. Their mastery of the necessary skills, knowledge and competencies via training will lead to effective and efficient delivery of consumer health information service in public libraries, and ultimately generate optimal patron experiences.     

Measures of Information Seeking: A Validation Study in the Context of Nonmedical Drug Use Behaviors

Health information is readily available and easily obtained from a variety of media and interpersonal sources. Although several studies have examined health-related information seeking, a comprehensive validation study of this measure is still needed. This study uses a longitudinal cohort study of Israeli university students (N = 800) aged 18–30, and a cross-sectional sample of U.S. college students (N = 498) to validate measures of information seeking about the nonmedical use of two drugs (marijuana and amphetamines) from a range of media and interpersonal sources. Information seeking measures for both drug types showed good convergent, discriminant, nomological, and test-retest validity. Results offer support for the use of these measures as valid indicators of the constructs for which they were designed. Implications for the use of these measures in future research are discussed.     

Tracing the Sources

This article explores health journalists’ sourcing patterns in the Dutch-speaking part of Belgium across a range of different media including newspapers, magazines, radio, television and online health news websites. A cross-sectional quantitative content analysis of health news items collected in February 2015 (N?=?981) was established to examine the number and origin (e.g. industry, citizens, experts) of sources (N?=?1998) mentioned in health news stories with particular attention paid to differences across various media types. Despite recent claims of media convergence, cross-media comparisons are scarce and, for a specialized beat such as health, nonexistent. The key findings of this study indicate that ordinary citizens and academic experts constitute the two largest source categories. The small share of industry-related sources confirms journalists’ skeptical attitude towards content provided by the industry. But on closer inspection, large differences can be observed across various media types. On the one hand, ordinary citizens occur with relatively high frequency on television but hardly make an appearance in online news items. Academic sources, on the other hand, are dominant online but nearly absent in television news items. In sum, this analysis demonstrates that health journalists’ source uses differ across various media platforms.     

Linking Exposure to Outcomes: Early Adolescents' Consumption of Sexual Content in Six Media

A media-use questionnaire was completed by 3,261 7th and 8th graders and a subsample of 1,074 respondents was interviewed about their sexual attitudes and behaviors. Based on results from the media survey, respondents' top television shows, movies, music, Internet sites, and newspapers were content analyzed for portrayals or references to pubertal development, romantic relationships, body exposure or nudity, sexual innuendo, touching and kissing, and sexual intercourse. Overall, 11% of the media used by respondents contained sexual content. A measure called the Sexual Media Diet (SMD) was developed to assess each individual's exposure to sexual content in the media, based on the combination of media consumption and content. The SMD measure showed a statistically significant association with adolescents' sexual activity and future intentions to be sexually active, with measures of movie and music exposure showing the strongest associations.     

Influences on the Construction of Health News: The Reporting Practices of Local Television News Health Journalists

Local television news remains a primary news source for Americans and is a key source of consumer health information. This study explores why local television health journalists cover particular topics and assesses why health journalism newsgathering practices often differ from the normative newsgathering practices of general assignment reporters. Fifteen in-depth telephone interviews were conducted with health journalists from varying geographical regions and media markets. Influence from local hospitals and personal interest in a health topic often determined the health content the journalists produced. Journalists said it was difficult to cover health issues in addition to other newsroom responsibilities.

Producing PSAs on consumer culture: youth reception of advertising

This study is a qualitative analysis of Public Service Announcement (PSA) storyboards produced by 177 fourth and sixth-grade students as part of a Media Literacy Education program on advertising and commercial culture. The program curriculum addressed the ubiquity and hidden nature of ads, as well as gender portrayals, violence, and nutritional messages in advertising content. Textual analysis revealed differing patterns in student reception of the varied lesson topics. Students called for specific behavioral changes in PSAs for the topics of nutrition and gender, although most were limited to non-media-related behaviors such as improving eating habits and encouraging fluidity across roles more traditionally associated with masculinity or with femininity. The analysis also suggested responsibility for the problems students identified with advertising were largely based on individual, consumerist perspectives rather than on collective or social, citizen-based terms. Fourth graders’ storyboards especially indicated an apparent mimicry of mainstream commercial productions and practices. The analysis further explores these fourth and sixth graders’ underlying orientations toward the U.S. commercial media system as well as the potential strengths and limitations of a production component in MLE programs to promote outcomes associated with critical media literacy.

Boys Will Be Boys and Girls Better Be Prepared: An Analysis of the Rare Sexual Health Messages in Young Adolescents' Media

Despite concerns about high rates of teen pregnancy and sexually transmitted disease in the United States, the mass media adolescents attend to most frequently include little accurate information about sexual health. In this study, a preliminary quantitative analysis of the sexual content in four media (television, magazines, music, and movies) popular among 3,261 Black and White adolescents (12–14 years old) found that less than one half of 1% of the content included information about or depictions of sexually healthy behavior. A qualitative analysis of the relatively rare instances of sexual health content revealed that across all four media the sexual health content was ambiguous and/or inaccurate, reinforced traditional gender stereotypes that males seek sex and females are responsible for protection against pregnancy, and presented puberty as funny and contraception as embarrassing or humiliating. These analyses suggest that significant changes in the media's presentations of sexuality would be required if the media are ever to be considered a healthy part of adolescents' sexual socialization.     

A Measure of Perceived Argument Strength: Reliability and Validity

Studies of the content of persuasive messages in which the central arguments of the message are scrutinized have traditionally relied on the technique of thought-listing to assess argument strength. Although the validity of the thought-listing procedure is well documented, its utility can be limited in situations involving nonadult populations and sensitive topics. In this paper, we present a self-reported scale that can be used to assess perceived argument strength in contexts where thought-listing may be less appropriate. This scale taps into perceived argument strength from multiple points of view, including but also extending beyond the potential of the argument to elicit positive and negative thoughts. Reliability and validity of this scale were assessed in health communication contexts involving anti-drug public service announcements (PSAs) directed at adolescents and anti-smoking PSAs targeting adults. Evidence of convergence between this scale and the thought-listing technique was also obtained using the classical comprehensive exam arguments.
