Concept: Media influence


Mass media plays an important role in communicating about health research and services to patients, and in shaping public perceptions and decisions about health. Healthcare professionals also play an important role in providing patients with credible, evidence-based and up-to-date information on a wide range of health issues. This study aims to explore primary care nurses' experiences of how mass media influences frontline healthcare.

Through a systematic review of the literature, this article summarizes and evaluates evidence for the effectiveness of mass media interventions for child survival. To be included, studies had to describe a mass media intervention; address a child survival health topic; present quantitative data from a low- or middle-income country; use an evaluation design that compared outcomes using pre- and postintervention data, treatment versus comparison groups, or postintervention data across levels of exposure; and report a behavioral or health outcome. The 111 campaign evaluations that met the inclusion criteria included 15 diarrheal disease, 8 immunization, 2 malaria, 14 nutrition, 1 preventing mother-to-child transmission of HIV, 4 respiratory disease, and 67 reproductive health interventions. These evaluations were then sorted into weak (n = 33), moderate (n = 32), and stronger evaluations (n = 46) on the basis of the sampling method, the evaluation design, and efforts to address threats to inference of mass media effects. The moderate and stronger evaluations provide evidence that mass media-centric campaigns can positively impact a wide range of child survival health behaviors.

A large body of literature has demonstrated mass media effects on body image and disordered eating. More recently, research in this area has turned to ‘new’ forms of media, such as the Internet, and particularly Social Networking Sites (SNSs). A systematic search for peer-reviewed articles on SNS use and body image and eating disorders resulted in 20 studies meeting specific inclusion criteria. As a whole, these articles demonstrated that use of SNSs is associated with body image and disordered eating. Specific SNS activities, such as viewing and uploading photos and seeking negative feedback via status updates, were identified as particularly problematic. A small number of studies also addressed underlying processes and found that appearance-based social comparison mediated the relationship between SNS use and body image and eating concerns. Gender was not found to be a moderating factor. It was concluded that, although there is a good deal of correlational research supporting the maladaptive effect of SNS use on body image and disordered eating, more longitudinal and experimental studies are needed.

Mass media influence public acceptability, and hence feasibility, of public health interventions. This study investigates newsprint constructions of the alcohol problem and minimum unit pricing (MUP).

For nearly half a century, psychologists, pediatricians and psychiatrists have studied the potential impact of media violence on aggression and societal violence, particularly among youth. Despite hundreds of studies, scholars have failed to find consensus on potential effects. Nonetheless, professional organizations such as the American Academy of Pediatrics and American Psychological Association have released policy statements conclusively linking violent media to societal concerns. In reaction, some scholars have accused these professional groups of distorting evidence and failing to inform the public of the inconsistent nature of studies in this field. The current paper reviews recent research on media violence. It concludes that caution is recommended in public statements regarding media effects and that professional groups risk serious reputation damage with policy statements calling for behavioral change without clear reflection of the current evidence-base of the research. Recommendations are provided for practitioners and for science policy.

During 2013, isolation of a wild type 1 poliovirus from routine sewage sample in Israel, led to a national OPV campaign. During this period, there was a constant cover of the outbreak by the mass media.

Decades of research have shown that violent media exposure is one risk factor for aggression. This review presents findings from recent cross-sectional, experimental, and longitudinal studies, demonstrating the triangulation of evidence within the field. Importantly, this review also illustrates how media violence research has started to move away from merely establishing the existence of media effects and instead has begun to investigate the mechanisms underlying these effects and their limitations. Such studies range from investigations into cross-cultural differences to neurophysiological effects, and the interplay between media, individual, and contextual factors. Although violent media effects have been well-established for some time, they are not monolithic, and recent findings continue to shed light on the nuances and complexities of such effects.

The current study aimed to assess Jordanian parents' knowledge and beliefs about the effects of violent media on children’s aggressive behavior. A sample of 262 parents of children aged 6-11 years completed a Media Quotient questionnaire about children’s media habits, media effects, and children’s aggressive behavior. Parents reported that their children spend an average of 4.83 h (SD = 2.12) watching TV, 3.20 h (SD = 2.29) playing video games, 1.07 h (SD = 0.88) listening to music, and only 0.52 min (SD = 0.67) reading for pleasure per day. Parents have a moderate level of knowledge about the media effect (M = 15.49, SD = 3.439). Children of parents who have adequate knowledge about the media effect, spend less time watching TV (r = -.355, p < .001), playing video games (r = -.265, p < .001), and listening to music (r = -.347, p < .001). Ninety-two percent (n = 241) of parents were concerned about the amount of sexual and of violent content their children see in movies or on TV. Children who spend more time playing video games (r = -.201, p = .004) show aggressive relational behavior. This study suggests that increasing parents' knowledge of media of evidence-based programs may have a protective effect on children's behavior.

In general, media coverage would not be implemented unless the number of infected cases reaches some critical number. To reflect this feature, we incorporate the media effect and a critical number of infected cases into the disease transmission rate and consider an susceptible-infected-susceptible epidemic model with logistic growth. Our model analysis shows that early media alert and strong media effects are preferable to decrease the numbers of infected cases at endemic equilibria. Furthermore, we noticed that the model may have up to three endemic equilibria and bi-stability can occur in a threshold interval for the critical number. Note that the interval depends on parameters for the focal disease and the media effect. It is possible to roughly estimate the interval for re-emerging diseases in a given region. Therefore, the result could be useful to health policymakers. Global stability is also obtained when the model admits a unique endemic equilibrium.

In this study, we evaluated associations of experiences with mass media imported from Western nations such as the United States versus mass media from China and other Asian countries with eating and body image disturbances of young Chinese women. Participating women (N=456) completed self-report measures of disordered eating, specific sources of appearance dissatisfaction (fatness, facial features, stature), and Western versus Chinese/Asian mass media influences. The sample was significantly more likely to report perceived pressure from, comparisons with, and preferences for physical appearance depictions in Chinese/Asian mass media than Western media. Chinese/Asian media influences also combined for more unique variance in prediction models for all disturbances except stature concerns. While experiences with Western media were related to disturbances as well, the overall impact of Chinese/Asian media influences was more prominent.
