Suicide has been one of the most popular reasons for death among teens and twenties in Korea for many years. By several factors such as anomie in our society, moral hazard, and lack of the system which could keep people away from suicide, our country has become one of the places where young people consider killing themselves very often. Under this tragic situation, many parties in our society have made diverse efforts, and PSAs (Public Service Announcements) has been one of the major tools used to decrease the rate of suicide. However, investigating how much those communication efforts are actually effective has not been popular enough yet. In this exploratory study, the authors examined people’s personal characteristics (i.e., demographic information, the level of self-esteem, the general perceptions about suicide, the level of depression lately), and try to figure out if there are any correlations between the people’s personal characteristics and their attitude toward the PSAs. Secondly, this study also explored what type(s) of the PSAs dealing with preventing suicide could be more appealing than others to the people. The different PSAs used in the experiment were created based upon two independent variables: 1. Appeal (Emotional and Rational), 2. Model (Peer groups and Medical specialists). In the results, it was found that the people who have high level of self-esteem answered that they had more positive opinions toward the PSAs. Also, using rational messages and medical specialists in the PSAa was the best combination.
