We used the self-reported 27-item Child Depression Inventory to investigate the rate and correlates of depressive symptoms among 5409 secondary school adolescents in Oman. Being female was a significant predictor of adolescent depression in bivariate analysis, but adjusting to other predictors in multivariate analysis, it was no longer a significant independent risk factor. History of mental illness, high score in negative health locus of control, low score in positive health locus of control, not taking breakfast, poor relationship with family members, friends and teachers and physical abuse during adolescence significantly predicted depressive symptoms in the logistic regression model. Having a hobby and never dropping a class were protective variables.
