Abstract

Patterns and correlates of comorbidity, as well as differences in manifest depressive profiles were investigated in a sample of depressed adolescents. A sub-sample of the youth were characterized as belonging to either a Pure depression group, an Internalizing group (depression and co-occurring internalizing disorders), or an Externalizing group (depression and co-occurring externalizing disorders). Item response theory (IRT) and differential item functioning (DIF) were used to assess whether the depressed adolescents from the different comorbidity groups presented with different depressive symptoms. Results indicated that the comorbidity groups were meaningfully distinct in terms of psychosocial correlates as well as showed differences in depressive symptom profiles as informed by DIF analyses. In particular, the comorbidity groups differed in terms of presentation of psychomotor changes and cognitive impairments. Implications for assessment are discussed.
Voetnoten
1
IRT involves a modeling estimation process and thus not all data sets are amenable to its use. When this is the case the parameters that characterize the items and responders have less meaning and using the parameters to assess the relationship between items and individuals may result in spurious conclusions.
 
2
Only those adolescents who met full criteria for ADD as operationalized by the Diagnostic and Statistical Manual of Mental Disorders (4th Ed., DSM-IV; American Psychiatric Association 1994) at the time of the assessment were considered as having ADD as a comorbid disorder above MDD. Those adolescents who were being successfully treated for ADD with a pharmacological agent and did not meet criteria for ADD at the time of the assessment were not considered as having a comorbid ADD diagnosis.
