Studies to assess differences in the responses of youth to various types of have usually used controlled exposures; less often, they have employed naturalistic exposures. Despite the common use of television, radio, and outdoor advertising in many state and national antismoking campaigns, few studies have examined the relative effectiveness of these different formats, although commercial information suggests that television has the broadest reach.

Early reviews of the published literature focused heavily on the findings of some of the controlled field experiments on the effectiveness of community-based antismoking programs for youth. In controlled-exposure studies, youth typically view a series of messages and then either discuss their reactions to them often in focus groups or complete an experimental study.
It is also possible that youth will complete cognitive processing tasks Shen et al. Cify recent years, antismoking messages have increasingly been presented via antitobacco Web sites.
Adding to this literature, a longitudinal controlled field trial by Solomon and colleagues included four matched pairs of media markets across four states randomly allocated to receive a 3-year television-and-radio intervention to increase smoking cessation and reduce smoking prevalence among adolescents. Angus and colleagues reported that four of five studies reviewed found that industry campaigns performed poorly compared with tobacco control campaigns.
Of the 12 studies that examined attitudes or beliefs relating to smoking Murray et al. The NCI review of the media and tobacco use described above highlights the difficulty of evaluating the media components of several early quasi-experimental studies of community-based cardiovascular programs because the media elements were combined with other program elements e.
There were no effects for and year-olds and no effects on most knowledge and attitude measures. Regardless, some authorities suggest that integrating media campaigns within a broader tobacco control program is important to their effectiveness Schar et al. In that study, Flynn and colleagues examined the effects of a media television and radio -plus-school intervention refusal skills, accurate social norms, positive views of nonsmoking and of a school intervention alone that both ran over 4 years.
Intensity and duration. Longitudinal population studies. There was evidence, however, of a strong secular trend that may have reduced the ability to detect effects Winkleby et al. Wakefield and colleagues ac also highlighted the idea that the effects seem to be more reliable when exposure occurs in preadolescence or early adolescence and when lead to emotional arousal. Bremerton chat rooms adult, most analyses were not based on the primary sampling units considered as a whole that received the intervention i.
Subsequent reviews Farrelly et al.
Use of multiple measures during and after the campaign Popham et al. Those in the intervention communities had greater cessation rates an In pune, another cardiovascular program aimed primarily at adults, pinw Stanford Five-City Project, allowed for the examination prostitute locations lowestoft the media effects alone and did not show any differences between intervention and control communities in the prevalence of smoking that could be traced to the media component.
Assessments at the end of the 4-year intervention and then at a 2-year follow-up Flynn et al. These programs varied greatly in the length and intensity of exposure to the campaign message and the time to follow-up assessment.
Supporting this research, a new study by Farrelly and colleagues found that at 3-year follow-up, exposure to the Philip Morris campaign was associated with more favorable beliefs and attitudes toward tobacco companies and a trend for weaker intentions not to smoke. This makes message testing extremely important. GRPs measure the relative reach and frequency of exposure to the campaign among the target audience within specific media markets.
These studies pien used a comprehensive set of potential confounders, but only one Terry-McElrath et al.
Some of the cross-sectional studies used post-only White et al. One review Schar et al. It should be noted, however, that state tobacco control campaigns that aired during the — period of this study may not have been broadcast at a level sufficient to detect the point of wear out among to year-olds provo escort ad average was just 1.
Fourteen of 16 cross-sectional population studies that examined smoking behavior i. One of these studies showed that youth who recalled the industry campaigns were ificantly more likely than their unexposed peers to have intentions to smoke in the future Farrelly et al. Factors That May Optimize the Effectiveness of Mass Media Campaigns Mass media campaigns against smoking, especially those with televised components, require considerable investment, making it particularly important to understand the factors and strategies that optimize their effectiveness.
As outlined in a of reviews Pechmann ; Jepson et al.

Methodologic shortcomings highlighted by Hornik and NCI may explain some of the variation in findings from the controlled field trials. for Free looking for fun looking for woman that is after no stings fun want to be play toy I am 6ft and atheletic. A Cochrane review completed a few years later Sowden included longer-term follow-up reports for some of the studies Persoonal et al.
Later, Emery and colleagues reported that if the average exposure among youth was less than one state-sponsored antismoking ad over a 4-month period, there were no discernible effects. If those in the studies by Sly and colleagues who recalled the advertisements and those in the study by Siegel and Biener who completed the follow-up survey were relatively more likely to be nonsmokers, the possibility of finding an effect could well have been inflated.
A study of differences between de elements, persuasive strategies, and information content across the Web sites of youth antitobacco organizations which also included the areas for prevention of youth smoking on tobacco industry Web sites indicated that the industry sites provided the weakest persuasive messages; grassroots costkids. The limitations of these controlled-exposure methods are that the exposure does not mimic real-world viewing contexts and that one cannot examine the effects of multiple exposures occurring over months and years.
YouTube also allows viewers to post comments about videos local chat lines in port elgin send links to others. Controlled exposure and naturalistic exposure studies examining the relative effectiveness of different advertising messages for youth. It is unclear whether the lack of success of these radio campaigns was due to the format, the messages typically broadcast on the radio stations, or the lower population reached by radio.
The effects of antismoking messages delivered via text messaging and the use of this technology as a way for smokers to seek help for quitting smoking after exposure to antismoking messages is another important area for research. Therefore, the extent to which these messages would be effective at the level of a broad population-based mass media campaign is unclear.
Only one of the four reviewed studies that examined the effect of media alone found a positive effect Hafstad et al. Only Arizona in andFlorida inMinnesota inand Utah in — averaged more than four exposures per month to state antitobacco among to year-olds Szczypka et al.

Still, a key difficulty in attempting to assess the specific media effects of statewide and national media campaigns is the fact that most were developed and run within the context of broader tobacco control programs and activities, such as tax increases Friend and Levy ; Farrelly et al. This suggests that in efforts to reduce youth smoking, there is a threshold of exposure below which antitobacco advertising may not have an influence, and effects increase with increasing exposure up to four per month CDC b.
The ruling by the Federal Communications Commission that the Fairness Doctrine applied to cigarette advertising provided the first chance to examine the effects of antismoking messages on youth smoking. A new series of citu studies added to this literature Zhao and Pechmann by examining four versions of the same basic social-disapproval antismoking message depicting nrw gathering of young college students that varied along two dimensions positive vs.
The NCI review of the media and tobacco use noted that some themes e. The video-sharing Web site YouTube provides another modality through which youth may be exposed to both traditional and innovative antitobacco messages from antitobacco organizations and motivated individuals e.
The findings from these and other cross-sectional, population-based evaluations of state and national anti-smoking campaigns developed by tobacco control programs can be more fully understood by examining the reported findings from 20 relevant papers cited in the three most recent comprehensive reviews Richardson et al. Determining the impact of messages conveyed through this medium is a fertile area for new research.
