Two experimental studies test the effectiveness of health versus appearance-related arguments in two-sided messages. The first
study shows that two-sided messages to discourage suntanning are more effective when using appearance-focused instead of health-focused
arguments. Study 2 elaborates on the underlying mechanism and extends the generalization of the results of the first study,
by investigating two-sided messages to promote physical exercise. The results show that for health-motivated consumers, a
health-focused message is more effective, whereas for appearance-motivated consumers, an appearance-focused message is more
effective. This matching effect is mediated by argument relevance.
