Discussion Exposure measure is really high vs.
low exposure, not any vs. none Cannot conclude that all anti-
smoking media campaigns are likely to be effective
Cannot necessarily conclude that radio and outdoor advertisements are not effective
Possibility of unknown confounder
Conclusion Strong evidence for a significant effect of statewide anti-smoking media campaign on youth smoking initiation
Effect restricted to younger adolescents
II. Effectiveness by type of TV advertisement
Adult ’93 to ’96 Youth ’93 to ’97 Youth ’99 Youth 2001/2 Hispanic vs non-Hispanic 2001/2
Research Tools Independent judges (youth and
adults) To establish characteristics of
advertisements Population-based telephone surveys
To assess how adults and youth in Massachusetts have reacted to the campaign
Independent Judges
View TV spots and rate characteristics “How well do each of following
describe the advertisement?” 1 = Not at all 7 = Very much
Judges’ Rating Scales(1 to 7) Sad Frightening Funny Emotionally
moving Believable Interesting Phony
Annoying Entertaining Reassuring Helpful Offensive Important Silly
Advertising parameters Negative Emotion: Sad,
frightening, disturbing Positive Emotion: Happy, funny,
entertaining Level of Emotion: Powerful,
emotionally moving Cognitive quality: Makes you think,
interesting
Message Identification What was the main message of
the ad? (Check one only).“Cigarettes and cigarette smoke are bad
for people’s health (Illness)“Tobacco companies are bad (Anti-
industry)“Teenagers shouldn’t smoke cigarettes
(Norms)
Relationships between message and affect Illness message: High negative
affect, high emotion Norms message: Varies – usually
high positive affect, low emotion Anti-industry message: Varies with
execution
Population Survey Approach Select subset of ads for
theoretical/conceptual purpose Assess recall Assess perceived effectiveness
Measurement of recall Aided: Gives brief description Confirmed recall: Requests details Unaided: Asks for free recall and
description of ad seen recently
Measurement of perceived effectiveness How good an anti-tobacco ad? (0
to 10) How it affects feelings about
cigarettes (feel worse, feel better, no change)
How much affects smokers’ motivation to quit (0 to 10)

Conclusions: Features of Effective Anti-tobacco Ads Evoke strong negative emotion Portray serious harm done by
tobacco use in authentic way
Ads youth perceived as effective... Target adult smoking Portray harm done to family by
second-hand smoke Reveal industry responsibility for
serious harm in an evocative way Avoid use of humor
Theoretical basis for emotional advertising Cognitive consistency
Negative emotion -> Increased risk, decreased benefit
Positive emotion -> Decreased risk, increased benefit
Learning theory High emotion ->greater recall
