Attention-deficit/hyperactivity disorder and scholastic achievement: a model of dual developmental pathways.

A conceptual model has recently been hypothesized in which parallel but correlated developmental pathways exist for attention deficit behaviors and conduct problems. An important component of this model suggests that attention deficit behaviors are related to later scholastic underachievement, whereas conduct problems are unrelated to scholastic underachievement except by their common correlation with attention deficit and intelligence. The present study replicated the general model using a cross-sectional sample of 325 children, and examined whether hypothesized dual pathways (behavioral and cognitive) better account for the relationship between attention deficit, intelligence, and later scholastic achievement. Results of the structural equation modeling analysis were consistent with the hypothesized dual pathway model and suggest that school behavior and select cognitive abilities serve as important mediators between attention deficit, intelligence, and later scholastic achievement. Implications of these results for understanding the developmental trajectory of children with attention deficit and general theoretical models of ADHD are discussed.

Problem of item overlap between the psychopathy screening device and attention deficit hyperactivity disorder, oppositional defiant disorder, and conduct disorder rating scales.

Content validity requires a clear definition of the construct of interest and the delineation of the construct from similar constructs. Content validity also requires that the items be representative of the construct as well as specific to the construct. An examination of the items on the Psychopathy Screening Device (PSD), a parent- and teacher-rating scale of childhood psychopathy, indicates significant overlap with the symptoms and associated features of attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). The failure of the PSD to have unique items results in poor discriminant validity with ADHD, ODD, and CD rating scales. More careful attention to content validation guidelines is required to develop a more useful measure of childhood psychopathy.

The problems of internal validation without a theoretical context: the different conceptual underpinnings of psychopathy and the disruptive behavior disorder criteria.

G. L. Burns (2000) has concluded that the Psychopathy Screening Device's content is limited because it contains items that overlap with criteria for several disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM). The problem with G. L. Burns's analysis is that it was conducted without an adequate understanding or specification of the conceptual underpinnings of either the construct of psychopathy or the constructs assessed by the DSM criteria. This reply attempts to clarify these conceptual frameworks to illustrate that to judge the adequacy of the content of a measure of psychopathy by comparing it with DSM criteria is inconsistent with the differing theoretical frameworks underlying these classification systems. Forcing measures of psychopathy to be designed around DSM criteria leads to inadequate measures of psychopathy and can limit advances both in our understanding of developmental precursors to psychopathy and in the classification of DSM disorders.

Gene-environment interplay in oppositional defiant and conduct disorder.

Oppositional defiant and conduct disorder is a disturbance in behavior that is characterized by aggressive and antisocial acts. At present, genetic research on conduct disorder has raised more questions than it has answered, and basic questions such as the heritability of childhood antisocial behavior cannot yet be answered with certainty. Current research, however, has consistently highlighted the importance of gene-environment interplay in antisocial behavior.

[Anxiety of hysterical exaction (author's transl)].

Fear in childhood is a quite common symptom and varies in importance according to age and stage of development. Intelligence, psychic constitution and special sensibility influence and coin the readiness and reasons for fear. Fear, however, can also be learned by reinforcement, imitation and identification. The reaction of the environment, in particular that of the parents, may fix physiological fear reactions of the child and these may be used in order to derive advantage. By means of several cases the reader is shown that fear in childhood is not rarely the expression of hysterical exaction. This publication wants especially to point to this kind of child neurosis because of the fact that even physicians and pedagogues submit to this exaction of pity and instead of demanding adequate work treat the child with indulgence or advise to do so. In this way the wrong attitude of the child becomes even more fixed. By his reception at a psychiatric ward for children this circulus vitiosus is usally soon interrupted. If the success of this therapy is to last, the treatment and advise of the whole family must begin synchronously and must often be continued for a long time.

[Neuropsychological assessment of ADHD subtypes].

Starting from a discussion of the validity of neuropsychological methods for the diagnosis of ADHD the results of an own study are presented. What is the diagnostic value of the German version of the CPT (Continuous Performance Task) and the DAT (Dortmunder Aufmerksamkeitstest) in discriminating ADHD subtypes (according to DSM-IV) and in which areas do the children of each subtype differ from a control group of normal children? The computer versions of the CPT and DAT were administered to 14 boys with the "combined subtype" of ADHD, 14 boys with the "predominantly inattentive type" of ADHD and 18 boys without clinical signs; all groups were matched in age and intelligence. Subsequently the mean differences between the various test parameters were assessed as to their significance. Contrary to other studies there were no significant differences either between both ADHS types or relative to the control group with regard to the CPT omission errors and the reaction time. There were differences in the reaction variability both between the ADHD subtypes and relative to the control group. Only the "combined subtype", not the "pre-dominantly inattentive type" differed from the control group as to the CPT commission errors. Regarding the DAT, there were significant differences between all three groups regarding both the solution quality and the response delay.

Evidence of utilization behavior in children with ADHD.

The purpose of this study was to investigate whether inappropriate/excessive motor activity seen in children with Attention Deficit Hyperactivity Disorder (ADHD) could be characterized as Utilization Behavior (UB). Given evidence that the neuropathology of ADHD may involve frontal-striatal systems, we investigated the possibility that children with ADHD may demonstrate "utilization behavior." Utilization Behavior (UB) is a neurobehavioral syndrome documented in individuals with damage or dysfunction in the frontal areas of the brain; patients exhibiting UB are often described as reaching out and utilizing objects in the environment in an automatic and inappropriate manner. The sample consisted of two group of children; children with ADHD (n = 32) and control children (n = 31). Children were assessed individually in a testing room where various objects, selected to elicit UB, were present. They completed cognitive tests and also were allowed to engage in an unsupervised activity. Testing sessions were videotaped and instances of physical activity (i.e., upper limb motor activity and utilization of objects) were counted by two raters. Results indicated high levels of object utilization in approximately one-half of the children with ADHD, whereas almost no such behavior was observed in controls. This behavior did not appear to be a result of generally heightened activity levels or due to instruction set, but differed according to object familiarity and object visibility. Levels of UB were statistically associated with the severity of hyperactivity, as reported by parents, of children with ADHD. This study suggests that inappropriate/excessive motor activity may, at least in part, be characterized as UB in some children with ADHD.

Risperidone: new indication. Behavioural disorders in children with autism or mental disabilities: no progress.

(1) Sedative drugs are one option when autistic or mentally disabled children have behavioural disorders that place them (or other people) in physical danger. Among the classic neuroleptics, haloperidol is the drug with the best-documented efficacy and safety. Placebo-controlled trials have also shown lithium to be effective for this use. (2) Clinical evaluation of risperidone in children with mental disabilities includes 3 placebo-controlled double-blind trials, 2 of which involved 118 and 110 children aged from 5 to 12 years who were treated for 6 weeks. All 3 trials showed a partial behavioural improvement in about 75% of children receiving risperidone, versus about 30% of children in the placebo groups. (3) Clinical evaluation of risperidone in autistic children includes 2 placebo-controlled double-blind trials involving 110 and 79 children who were treated for 8 weeks. One of these studies has been published in detail: 69% of children partially improved with risperidone, versus 12% of the children on placebo. (4) Given the absence of clinical trials comparing risperidone with haloperidol or lithium, there is no evidence that risperidone is more effective than these other treatments. (5) The principal adverse events observed in short-term trials of risperidone were drowsiness (affecting about 50% of children), weight gain (about 1.2 kg per month during the first months of treatment), and hyperprolactinaemia (affecting about 12% of children). Extrapyramidal disorders were infrequent during short-term trials, but their incidence reached about 25% after a year of risperidone treatment. (6) The impact of long-term risperidone therapy on growth and mental development is not known. (7) In France treatment is about 7 times more expensive with risperidone than with haloperidol. (8) In practice, the risk-benefit balance of risperidone in the treatment of autistic or mentally disabled children with behavioural disorders is no better overall than that of older products such as haloperidol and lithium, which, in the absence of anything better, remain the standard drugs.

[Autistic spectrum disorders in very young children: issues in the diagnostic process].

The diagnosis of very young children with autistic spectrum disorders and differentiating the disorder from mental retardation are difficult in the early years. Some efforts to improve diagnostic practice are reviewed. The usefulness of standardized behavioural rating scales, observation of core deficits in communication and play and parental reports are discussed in view of the author's experience with 13 children (2-4 years of age). Even in the case of diagnostic uncertainty, focussing early intervention on core symptoms of autism and supporting responsive parent-child interactions is recommended in order to prevent further social isolation of children with autistic features.

[Changes in the incidence of restrictive and confining measures in inpatient psychiatric treatment of children and adolescents with residential care experience before and after abolition of closed residential centers in Hamburg].

Results from the investigation of 542 medical records of children and adolescents being admitted to the department of psychiatry of the university of Hamburg are presented and discussed. Analysis of medical records concerned the frequency of admissions in general, the diagnosis conduct disorder, the frequency of closed ward admissions and the item residential care. Data from a time period before (1976-1978) and after (1985-1987) abolition of closed ward admissions to the department of psychiatry among children and adolescents with a history of residential care. Due to the lack of research accompanying the administrative measure of abandoning closed residential care and the thereof resulting methodological problems, the obtained result can not be looked at as a substantial proof but indicates a correlation between the abolition of closed residential care and the increase in closes ward admissions to psychiatric departments.
