BACKGROUND Symptoms of depression vary between the males and females. Depressed men show behaviors such as irritability, restlessness, difficulty in concentrating, and instead of the usual behaviors. Sleep disturbance is a common symptom in depressed men. Men are less likely to go to doctors and unconsciously show other behaviors such as anger instead of the sadness. It seems that considering depression as "feminine" is a great injustice toward male patients whom their illness will not be diagnosed nor treated. METHODS The sample consisted of 191 depressed adolescents, 108 males and 83 females aged 13-19 years old. Data collected for 10 years from 2005 to 2015 and their depressive symptoms were evaluated by the Beck Depression Inventory-Second Edition. RESULTS Depressed girls felt sadness, guilt, punishment, worthlessness, low energy and fatigue, or more asthenia, whereas depressed boys have symptoms such as irritability, depression, suicidal thoughts, or desires to reduce their pleasure. The results of t-test showed that the difference between the total scores of boys and girls with depressive disorder (16.93) is significant at 0.001. F values for feeling sad (58.13), hatred of self (12.38), suicidal thoughts or desires (12.97), restlessness (17.35), and irritability (46. 41) were significant in the 0.001. CONCLUSIONS Experiencing depression in boys and girls according to the role of gender was different. Gender can have an effective role in showing depression symptoms in adolescents.
