AbstractMany schoolchildren suffer from being bullied during their school time. Therefore, this study examines whether moral courage can be increased by a moral courage training in order to intervene in such situations. Furthermore, this study should find out if adolescences who receive a moral courage training have more adequate skills to intervene against bullying as before. These questions were examined in a secondary school in Austria. The sample consists of 59 adolescences (26 females and 33 males). The results of this study revealed that the important social good of moral courage can be increased by a moral courage training. The participants of the moral courage training have more intervention skills for acting morally courageous against slogans as before. Additionally, they are equipped with more skills to show moral courage at school and against physical violence than before participating in the training. Therefore, a moral courage training is a valuable possibility to reduce bullying.Keywords:Moral courage, training, evaluation, increase moral courage, bullying.
