So what type of anti-smoking ads can produce better psychological effect? Smoking and non-smoking subjects respond to different types of anti-smoking ads have any different? For domestic public, whether the effects of self-directed threat ads is better than other-directed threat ads? This thesis focuses on discussing the impact of anti-smoking advertising effectiveness on the smoking status of subject, fear strength and threat types. And further explore the differences of anti-smoking ads effect in the threat types ads for different self-oriented audience.Study 1 adopted a pretest-post test design of 2(smoking status: smoking, non-smoking) x 2(fear strength: high fear, low fear) x 2(threat types: self-directed threat, other-directed threat), 224 university students were selected as subjects, with the questionnaire method to explore the interaction on advertising effects of the smoking status, treat types and fear strength.Study 2 using IAT test measured the self-orientation of the smoking subjects, Through data analysis, the self-orientation is a factor of effectiveness differences of different threat types of anti-smoking ads was checked, and explore the possible interaction on advertising effects of the self-orientation and threat types.The results indicated that:(1) The status of smoking has a great difference in advertising effects. The non-smokers have more positive advertising attitude, smoking attitude change and intent change than smokers after viewing the anti-smoking advertisement.(2) The fear strength has a great difference in advertising effects.

For high fear ads, the intent change is better when presented self-directed threat ads for smokers; exposed other-directed threat ads will have more intent change than self-directed threat ads for non-smokers. For other-directed threat ads, non-smokers exposed high fear ads have more intent change than smokers exposed high fear ads; non-smokers exposed high fear ads have more intent change than non-smokers exposed low fear ads.(5) The self-orientation is a factor of effectiveness differences of different threat types of anti-smoking ads.(6) In advertising effects,the interaction between threat types and self-orientation is obvious. For individual self, the effect is better when presented self-directed threat ads. And for collective self, exposed other-directed threat ads will have better effects than self-directed threat ads. |
