dc.description.abstract | In the present decade, adolescents' mental problems are known as critical problems which have many destructive consequences. This study aimed to measure students' happiness and psychological wellbeing status in a sample of high school students. The cross sectional study consisted of 403 randomly selected high school students in Tabriz, Iran. Numerous variables including general health status, happiness, self-efficacy, perceived stress, hopefulness and life satisfaction were measured by using selfreported written questionnaires. Significant relation observed between happiness and psychological well-being (r = 0.48). Those students with good relationship and those who had reported to enjoy attending social events indicated better mental health status. No causal inferences were investigated due to the non-experimental nature of the study. The findings also revealed that students with higher happiness score have a better school performance. Integration of happiness promotion initiatives into the comprehensive school health programs is recommended to have pleasant environments for a healthy population of adolescents. (C) 2015 Elsevier B.
