Suicide is a complex, multifactorial phenomenon that is difficult to understand and accept, affecting a significant and growing number of the world's population. However, it is permeated by taboos and prejudices that lack information and discussion. There is a need to demystify misconceptions surrounding the phenomenon and raise awareness about it, enabling the identification of risk factors, provide reception and direct the person to appropriate treatment. Therefore, this book aimed to investigate what academics at a university in Joinville know about the topic of suicide and to carry out a psychoeducational intervention. An action research approach was used. The data were analysed using the qualitative method, through content analysis. The proposal was carried out with 7 classes, encompassing 4 teaching areas of a university. The intervention was divided into two moments, the first consisting of a questionnaire with open and closed questions. In the second, a dynamic of myths and truths about the phenomenon was carried out, followed by a discussion debating the answers, relating to the contribution that each class could make to suicide prevention.
