Abstract
The aim of this study was to compare the relationship of personal strengths and negative emotions on the quality of life of 686 adolescent students by sex and socioeconomic strata from Bogotá city, Colombia. Instruments: Adolescent Resilience Scale ARS, Self-Trascendence Scale, adolescent version STS, Subjective Happiness Scale SHS, The Youth Life Orientation Test YLOT, Children’s Depression Inventory CDI, the Inventory of Daily Stressors Child IIEC and the KIDSCREEN-52. Results showed moderate levels in quality of life, resilience and low in negative emotions. It was found in the multiple linear regression analysis that personal strengths and negative emotions weigh on the quality of life in men more than women and in middle and high socioeconomic strata rather than low. Conclusion, quality of life in adolescents is mediated by self-transcendence and happiness and negative emotions as depression.
