The aim of this study was to determine well-being and its relationship to social support from friends and family communication in university students. A cross-sectional study was conducted with 1679 university students aged 18⁻25 years from four universities in Spain. Logistical regression models were tested (p < 0.05). The students in the last year of university reported higher well-being scores in comparison with students in the previous years. Well-being was inversely related to family communication problems. Family communication and social support from friends were the factors that associated the most with better well-being. All the regression models were statistically significant and explained from 16% of the well-being in Year 4 students until 34% of the well-being in Year 1 students. Our findings could be useful for developing interventions to promote health in order to improve college students' well-being. It is important for strategies to be developed in mental and family health areas.
