Abstract:
The Developmental Behavior Checklist (DBC; Einfeld & Tonge, 1995) is one of a very small number of psychopathology assessment instruments designed specifically for use with children and adolescents with mental retardation. In the present study, a factor analysis of the DBC was performed using a sample of 531 children and adolescents. This analysis revealed a factor structure sharing a good deal of overlap with the factor analyses of the DBC's developers. Furthermore, the high levels of internal consistency of the DBC subscales were replicated. Further research and development is needed on the DBC and other instruments for children and adolescents with mental retardation.
