One hundred children between the ages of 7 and 12 admitted to a hospital for orthopaedic procedures were studied to determine the frequency of depression, according to the DSM III diagnostic criteria for major depressive disorder. Of the total sample, 23 showed evidence of depression. Loss of interest or pleasure was the most frequent symptom. Significantly more parents of these depressed children were themselves found to have adjustment or emotional problems. The authors emphasize the importance of paying special attention to this high risk group of child patients because of their propensity to depression and other emotional disorders.
