In the last decade, suicide figures have shown an increase that led to its consideration as a public health problem by institutions such as the Pan American Health Organization and the World Health Organization. The department of Boyacá (Colombia) has not been an exception to this issue, reporting high suicide rates per number of inhabitants. This situation triggered the interest of a group of researchers from the Universidad de Boyacá, who, for years, have developed research projects with different populations from the area, which allowed them to identify the main risk factors and components for the construction of a suicide prevention proposal. Thus, the following book is divided into two parts and five chapters that address suicide as a public health problem in the international, national, and regional context. Likewise, this book includes the presentation of a prevention program supported by the research processes developed by the authors. This program is composed of 10 sessions that integrate self-control and problem-solving techniques, supported by the research processes developed by the authors.
