Abstract: | IntroductionThe difference between internalising disorders (anxious and depressive disorders) and externalising disorders (conduct disorder and oppositional defiant disorder) is largely accepted by clinicians and researchers. Although hyperactivity may seem linked with the externalising disorders, recent empirical research suggested it could be often comorbid with depression, and recent theoretical research suggested it could be, at least partially, founded on psychodynamic mechanisms intended to master separation anxiety. These works suggest that the internalising dimension of hyperactivity may have been underestimated in empirical research. The purpose of this paper is to assess the level of internalisation in hyperactivity.MethodTwenty five hyperactive children were compared with children presenting anxious disorders (N = 22), depressive disorder without suicidal ideation (N = 28), with suicidal ideation (N = 20), and academic learning disorders (N = 23). All diagnoses were made according to the ICD-10 criteria, which are very similar to the DSM criteria for anxious, depressive, and academic learning disorders, but are more stringent regarding hyperkinetic disorder than the DSM criteria for attention-deficit/hyperactivity disorder. Internalisation and externalisation were assessed by the Child Behavior Checklist (completed by one of their parents), and the presence of suicidal ideation was assessed on the basis of the Children Depression Inventory item 9.ResultsHyperactive children exhibit more internalisation problems than those with learning disorder, but less than those with anxious and depressive disorders. Unexpectedly, depressive children with suicidal ideation presented high levels of delinquent and aggressive behaviour, equal or superior to those of the hyperactive children.DiscussionThese findings bring partial support to the psychodynamic view of hyperactivity. But they also underscore the unexpectedly high rate of externalising symptoms among depressive-suicidal children, whose pathology is theoretically regarded as a typically internalising disorder. In conclusion, these results suggest the relationship between externalisation and internalisation could be more complex than is generally assumed, and support the possibility of simultaneous presence of high levels of externalisation and internalisation in some disorders. |
