Abstract
This study examined the relationship of life satisfaction with self-efficacy and perceived social support in 358 male and female adolescents from Concepcion (Chile), 15 to 19 years old. Results showed high levels of self-efficacy, perceived social support and life satisfaction in this sample. Both self-efficacy and social support had significant positive relationships with life satisfaction, with self-efficacy having more relationship with life satisfaction than perceived social support. Diverse explanatory factors for obtained results are proposed.
