“…The same circumstances wiU arise if the behavioural dimensions operate as risk factors for disorder. For example, numerous studies have shown the strong overlap between attention deficit (hyperactivity) and conduct disorders (Szatmari et ai, 1989;Taylor, 1988). Does this imply comorbidity between two different disorders or rather does it mean that both inattention/overactivity and aggressivity are risk factors for disruptive behaviour?…”

Abstract-Epidemiological data show that the co-occurrence of two or more supposedly separate child (and adult) psychiatric conditions far exceeds that expected by chance (clinic data cannot be used for this determination). The importance of comorbidity is shown and it is noted that it is not dealt with optimally in either DSM-III-R or IGD-9. Artifacts in the detection of comorbidity are considered in terms of referral and screening/surveiUance biases. Apparent comorbidity may also arise from various nosological considerations; these include the use of categories where dimensions might be more appropriate, overlapping diagnostic criteria, artificial subdivision of syndromes, one disorder representing an early manifestation of the other, and one disorder being part of the other. Possible explanations of true comorbidity are discussed with respect to shared and overlapping risk factors, the comorbid pattern constituting a distinct meaningful syndrome, and one disorder creating an increased risk for the other. Some possible means of investigating each of these possibilities are noted.

“…In the past the diagnostic criteria were criticized because diagnosticians often differed in their assessment of the same children (Quay, 1979;Taylor, 1988;Nelson-Gray, 1991;Swanson et al, 1998). To redress this, rating scales were developed to assess the hyperkinetic syndrome in children (Achenbach, 1991;Conners, 1970;Barkley, 1998).…”

This study uses the attention deficit/hyperactivity disorder (ADHD) symptom ratings of professional care workers to estimate the prevalence of ADHD symptoms among children in day treatment centres (N = 162) and residential treatment centres (N = 195) in Holland. Although further research is needed, the study supports the suggestion that such ratings can add to reliable diagnostic outcomes when assessing the behavioural symptoms of ADHD in children in the centres. It is estimated that nearly a fifth of the children in such centres exhibit the symptoms of ADHD in the judgement of professional care workers. Model testing using confirmatory factor analysis favours a dimensional behavioural model that comprises all the three constitutional symptom dimensions of ADHD (inattention, hyperactivity and impulsivity) instead of the two-factor model as used in the DSM-IV (inattention and hyperactivity/impulsivity). However, the differences of fit between both models were only small and the hyperactivity and impulsivity factors were highly correlated. This suggests that, in practice, a two-factor model can also be appropriate. The issue of whether a two-factor or a three-factor model is more appropriate thus remains unsolved in this study.
