Depression, like many psychiatric disorders, has a genetic component that makes it more likely that members of the same family will have the disorder. Depression in parents, particularly mothers, may put the children at greater risk for depression. When an adolescent whose parent is depressed develops depression himself or herself, treating both the parent and the adolescent may be more effective than treating only the adolescent. This study will test a depression treatment that targets depressed suicidal adolescents with a parent or primary caretaker who is also depressed and has a history of suicidality.
