ABSTRACT
OBJECTIVE: To investigate the clinical characteristics of depression in preschool children. METHOD: One hundred seventy-four subjects between the ages of 3.0 and 5.6 years were ascertained from community and clinical sites for a comprehensive assessment that included an age-appropriate psychiatric interview for parents. Modifications were made to the assessment of major depressive disorder (MDD) criteria so that age-appropriate manifestations of symptom states could be captured. Typical and "masked" symptoms of depression were investigated in three groups: depressed (who met all MDD criteria except duration criterion), those with nonaffective psychiatric disorders (who met criteria for attention-deficit/hyperactivity disorder and/or oppositional defiant disorder), and those who did not meet criteria for any psychiatric disorder. RESULTS: Depressed preschool children displayed "typical" symptoms and vegetative signs of depression more frequently than other nonaffective or "masked" symptoms. Anhedonia appeared to be a specific symptom and sadness/irritability appeared to be a sensitive symptom of preschool MDD. CONCLUSIONS: Clinicians should be alert to age-appropriate manifestations of typical MDD symptoms and vegetative signs when assessing preschool children for depression. "Masked" symptoms of depression occur in preschool children but do not predominate the clinical picture. Future studies specifically designed to investigate the specificity and sensitivity of the symptoms of preschool depression are now warranted.

OBJECTIVE: To investigate the validity of developmentally modified DSM-IV criteria for preschool major depressive disorder (MDD). METHOD: Subjects between the ages of 3.0 and 5.6 years were ascertained from community and clinical sites for a comprehensive assessment that included an age-appropriate psychiatric interview with the parent about the child. Minor developmental modifications to the formal DSM-IV MDD criteria were tested, including translations of symptoms to describe age-appropriate manifestations and setting aside the duration criterion. Preschool children who met modified criteria were compared with psychiatric and normal control groups. RESULTS: Validation for the modified criteria was supported by a specific and stable symptom constellation, social impairment, greater family histories of affective disorders, and higher child-reported symptoms of depression on an age-appropriate puppet interview. Preschool children with MDD displayed "typical" symptoms of depression, as well as vegetative signs. Standard DSM-IV criteria failed to capture 76% of children who met these modified criteria. CONCLUSIONS: Evidence that preschool children can manifest typical symptoms of MDD when age-adjusted symptoms states are assessed is provided. Findings also suggest that standard DSM-/V criteria may not be sufficiently sensitive for preschool children, as they failed to capture a substantial proportion of symptomatic children. Minor modifications to DSM-IV criteria are recommended to capture clinically significant preschool MDD.
