RESUMEN
This study seeks to know if there is a relationship between measures of suicidal ideation and cognitive orientation towards spirituality, religious attitudes and beliefs, and religious practice. A non-experimental, descriptive, and correlational design, cross-sectional and quantitative approach was used. The sample was made up of 1372 adolescents, 59.2% female, 40.8% male, mean age 14.57, s = 1.75, range 12-17 years old, students from public schools in two cities in Colombia. The results indicated an inverse relationship between negative suicidal ideation (NSI) and cognitive orientation towards spirituality, beliefs and attitudes, and religious practice, and a positive relationship between them and positive suicidal ideation. The regression analysis showed the contribution of spirituality, religious beliefs, and attitudes in the prediction of NSI. In conclusion, the dimensions of spirituality and religiosity can help reduce suicidal thinking, acting as protective factors. The cultivation of a spiritual and/or religious life can be suitable and complementary ways as measures of prevention of suicidal behaviour.
