Common and specific correlates of preadolescent internalizing and externalizing psychopathology

The specificity of various child characteristics and environmental correlates of childhood internalizing and externalizing problems was examined using both cross-sectional and longitudinal analyses (from ages 2-3 and 4-5 years) in a general population sample of 10-11-year-olds. Specificity was defined according to a between-subjects and a within-subjects method, using parent and teacher reports of psychopathology. Temperamental withdrawal, parental internalizing psychopathology, and early single parenthood (for girls) were identified as correlates that are specific for internalizing problems, whereas temperamental high general activity level was identified as externalizing-specific. Further, parenting stress, poor school results (only for boys), and stressful life events (only for girls) were found to be common correlates of psychopathology. Research implications regarding the findings and the use of a within-subjects method are discussed.
