Wagner and her colleagues studied 50 youngsters hospitalized for various psychiatric diagnoses, including major depression and bipolar disorder, who had suicidal ideas. About half of these young patients had attempted suicide. The researchers used the Children’s Attributional Style Questionnaire, the Hopelessness Scale for Children, and the Children’s Depression Inventory to identify subjects’ mental outlook, level of hope, and amount of depression both at the time of admission and upon discharge—that is, when the subjects were no longer harboring suicidal thoughts.
