Context effects in the behavioral ratings of hyperactivity

It was proposed that parents of hyperactive children would observe more problems at home in some but not all home contexts. To test this hypothesis, parents of teacher-identified hyperactive and nonhyperactive children were asked to complete a context-specific behavioral rating scale (Werry, 1968). Hyperactive children were rated by their parents as changing activities, talking, interrupting, and exhibiting dependency more than nonhyperactive children. Furthermore, those differences between hyperactive and control children were observed primarily in the play and homework contexts.This research was supported by a National Institute of Mental Health Grant MH(32282).     

Reading-disabled hyperactive children: A distinct subgroup of Attention Deficit Disorder with Hyperactivity?

Mixed hyperactive/reading-disabled children, selected from a large sample of hyperactive children, were compared to pure hyperactive children on demographic, behavioral, and neuropsychological measures. Children in the Mixed group were reading-disabled relative to age and IQ; those in the Pure group had achievement scores that were average relative to age and IQ. The Mixed group was significantly older than the Pure group; there were no differences in gender, race, or socioeconomic status. Behaviorally, the groups did not differ significantly on teacher ratings or on psychiatric ratings of aggression. The Mixed group had a significantly higher Performance IQ, whereas the Pure group had a significantly higher Verbal IQ and performed better on measures of cognitive impulsivity. Several other measures failed to distinguish the groups. The data give minimal support to the notion that pure hyperactive and mixed hyperative/reading-disabled children constitute distinct subgroups of Attention Deficit Disorder with Hyperactivity.This research was supported in part by Mental Health Clinical Research Grant MH-30906 and by U.

Videotape modeling for preschool children with low levels of social interaction and low peer involvement in play

This research evaluated a videotape modeling intervention for six preschool children who showed low levels of social involvement with peers in natural free-play settings. Observations across 14 weeks gave frequency and topographic data on social interactions and assessment of social involvement in play using the Parten Scale. Simultaneous observation of three children gave data on two comparison children for each target child. A multiple-baseline across-subjects design was used with two data analysis strategies. Averaged group data showed statistically significant increases in both interactions and social involvement in play. Visual analysis of the single-subject data, however, indicated no clear treatment outcome for two children, while four subjects showed a variable increase in social responding after viewing the modeling videotape. Session-by-session variability was a feature of the interaction rate measure for comparison children and for posttreatment phase data for target subjects.This research was supported by Grant No. 62-262-98 from the Mental Health Foundation of New Zealand and by University of Otago Research Committee Grant No. 37-877.

An analysis of the hyperactive syndrome: A comparison of hyperactive,behavior problem,asthmatic, and normal children

In an attempt to determine whether the commonly described deficits associated with hyperactivity — inappropriate activity, short attention span, low frustration tolerance, and impulsivity — are unique to this population, hyperactive, behavior problem, asthmatic, and normal control children were studied. The tests most often used in research with hyperactives were administered. Hyperactives, when compared to normals, did show deficits in the aforementioned areas. However, when compared to the behavior problem and asthmatic children only the attentional deficits clearly differentiated hyperactives from the other children.This research was supported, in part, by grants from the Ontario Ministry of Health (DM-304) and the Ontario Mental Health Foundation (#652-76A).     

The assessment of impulsivity and mediating behaviors in hyperactive and nonhyperactive boys

Twenty boys (6–8 years) rated by their teachers as hyperactive and a matched sample of nonhyperactive boys performed a task that required them to withhold responding for a set time interval in order to be rewarded (DRL 6-second schedule). Half of each group worked on a one-button console while the other half was provided with additional collateral buttons. Results indicated that hyperactive children were relatively unable to perform efficiently on the task, and that this deficit endured regardless of age, IQ, or experimental condition. DRL was thus found to discriminate accurately between teacher-rated and parent-rated hyperactive and nonhyperactive children. Furthermore, a wide variety of self-generated mediating behaviors was observed, and it was determined that a child's DRL performance was related to the kind of mediating behaviors he displayed. Results are discussed in terms of the clinical assessment of hyperactivity and the training of impulsive children.This report is based upon a dissertation submitted by the author in partial fulfillment for the Ph.D. degree.

Behavior problems in elementary school children

Two-year follow-up data for an ostensibly normal sample of children who had been previously characterized on a number of behavior problem dimensions by their teachers and peers were analyzed. In addition, 1-year follow-up data were presented for a group of extreme behavior children from the same school. The behavior dimensions of Distractibility and Conduct Problem were fairly stable over 2 years for girls and boys. In addition, Inadequacy—Immaturity was stable for girls and may mark more severe behavior problems for young girls. Behavior problems of young girls were more predictive of later achievement difficulties while behavior problems of boys were more prdictive of peer and teacher difficulty. Finally, teacher's clinical judgment was demonstrated to be useful for indexing behavior for hyperactive boys.Portions of this paper were presented at the New England Educational Research Organization Meeting, Provincetown, Massachusetts, May 1975.

The use of psychopharmacology to study reciprocal influences in parent-child interaction

The present paper reviews the possible utility and limitations of using behavior-modifying drugs to study reciprocal influences in parent-child interactions. Ideal circumstances for use of this approach are outlined and contrasted with the current status of the field of psychopharmacology. Numerous limitations to the approach are found. Yet the utility of the design is demonstrated in several studies of stimulant drug effects on the mother-child interactions of hyperactive children, and in one pilot study of the effects of diazepam, an anxiolytic, on these same interactions. The major pitfalls to this approach will quite likely be overcome by future research and the development of safer, more highly specific behavior-modifying drugs.Funding for this paper is derived from Grant No. 1-R01-MH32334-01 from the National Institute of Mental Health.     

Peer evaluations of the competence of children vulnerable to psychopathology

Peer evaluations of the behavior of 75 children of schizophrenic mothers, 57 children of depressed mothers, and 153 controls were collected using the Pupil Evaluation Inventory. The children, both boys and girls, were in grades 2 through 9. Both male and female children of schizophrenics were viewed more deviantly than controls on Aggression and Unhappiness-Withdrawal factors. Only the female children of schizophrenics were viewed as less likable than controls. In general, children of schizophrenics did not differ from children of depressives. The exception was the older daughters of schizophrenics, who were rated as more deviant than members of both the remaining groups.This research was supported by grant MH 21145 from the National Institute of Mental Health and by funds from the William T. Grant Foundation.     

Effects of color stimulation and information on the copying performance of attention-problem adolescents

The optimal stimulation theory proposes that hyperactive children are less tolerant of lower levels of arousal than nonhyperactive children and should thus derive greater gains from stimulation added to repetitive copying tasks than do comparisons. To test this hypothesis, 16 adolescents, rating high on attention and behavior problems, were matched on the basis of age and poor handwriting performance to 16 controls. Matched pairs were randomly assigned to treatment order (high-stimulation colored letters followed in 2 weeks by low-stimulation black letters or the reverse order) and to level of information (color added to difficult letter parts or added to randomly selected letters), counterbalanced for treatment order and level of information within each order. Errors and activity were subjected to a mixed-design analysis of covariance, with IQ the covariate. The major findings indicated that attention-problem adolescents performed better with high-stimulation task stimuli than with low, relative to the opposite performance pattern of controls. Different responding was significant for experimental but not for control children.This research was supported by National Institute of Mental Health Grant MH32282 to the first author.     

Assessment of a cognitive training program for hyperactive children

Modeling, self-verbalization, and self-reinforcement techniques were used to train hyperactive children in more effective and less impulsive strategies for approaching cognitive tasks, academic problems, and social situations. Eighteen hyperactive children took part in the training program. The control group, which received no training, consisted of 11 children, matched with the experimental group on age, IQ, and measures of hyperactivity and impulsivity. Several tests and measures, some of which have been shown to differentiate between hyperactive and normal children, were administered prior to training, at the end of the 3- month training period, and after a further 3- month period in which no training took place. The trained group showed significantly greater improvement on several of the measures, both at the time of posttesting and on the follow-up evaluation.This research was supported by Canada Council Grant #S74-0750, principal investigator, Virginia I.

Methylphenidate and cognitive therapy with add children: A methodological reconsideration

The present doubleblind study examined the effects of methylphenidate, cognitive therapy, and their combination in attention deficitdisordered (ADD) children. Four treatment groups were compared on measures of attentional deployment and cognitive style, tests of academic achievement, and behavioral rating scales. In contrast to a previous study conducted in this laboratory, children in this study were not receiving medication during posttesting. Results were interpreted to suggest that measurable effects of stimulant medication dissipate rapidly upon discontinuation of pharmacotherapy. The combination of methylphenidate and cognitive therapy was not found to be any more efficacious than either of the treatments studied alone. Discussion suggests that medication status at follow-up is an essential feature of research design.This research was supported in full by U.S. Public Health Service Grant No. MH 37-628 from the National Institute of Mental Health, Psychopharmacology Branch, and by Biomedical Research Award No. RR 0715807 from the National Institutes of Health, each awarded to R.

Effects of treatments and their outcomes on peer perceptions of a hyperactive child

In an exploration of the social impacts of treatments for hyperactivity, two age groups (kindergarteners and first-graders vs. fourth- and fifth-graders) heard about a hyperactive child whose problem was treated either by an internal and controllable means (effort) or by an external and uncontrollable means (medication) and whose behavior either did or did not improve. The attributions and affective responses of both age groups were influenced by both the nature and the effectiveness of treatment, and there was only weak support for the hypothesis that younger children are more influenced by treatment outcome than older children are. However, older children, conforming to attribution theory predictions, held target children more accountabe for the success or failure of their own efforts than for the outcomes of medication, particularly valuing the child whose own efforts succeeded. By contrast, young children judged the child whose efforts failed as more worthy of pride and more likable than the child whose medication failed. Implications for peer acceptance of hyperactive children over the childhood years are discussed.Portions of this paper were presented at the annual meeting of the Southeastern Psychological Association, Atlanta, March 1985.

Relations between hyperactive and aggressive behavior and peer relations at three elementary grade levels

Sociometrics and teacher ratings of hyperactivity and aggression were obtained on 390 boys in grades 1– 6 to explore the relative contributions of hyperactivity and aggression to children's social adjustment. Both hyperactivity and aggression were correlated with negative sociometric nominations at all grade levels; however, only hyperactivity showed consistent inverse correlations with positive sociometric nominations. In multiple regression analyses, hyperactivity contributed incremental variance to the prediction of problematic sociometric status at all grade levels, while aggression did so only at grades 3– 4. An examination of the core symptoms of hyperactivity revealed that motor hyperactivity, in the absence of impulsivity and inattention, did not predict negative sociometric status at any grade level. Subgroups of boys categorized as hyperactive only, aggressive only, hyperactive/aggressive, and nonhyperactive/nonaggressive controls were compared on teacher ratings and sociometrics. Hyperactive/aggressive boys had higher hyperactivity and aggression ratings than boys in either of the single- problem groups; all three behavior problem groups had more negative social status than controls. Developmental changes in children's normative expectations for social behavior were discussed as possible mechanisms mediating the age- related differences in relations among aggression, hyperactivity, and peer relations.This research is based on a dissertation submitted by the first author in partial fulfillment of the requirements for the Ph.D. degree in clinical psychology at The Pennsylvania State University.

Psychopathology in children of parents with recurrent depression

We examined the prevalence of psychopathology in children of parents with recurrent major depression (n=61)and children of normal control parents (n=46).Rates of psychopathology in the children of depressed parents were consistently higher when compared either with the control children or with rates of disorder reported for nonclinically referred children from other studies. Forty-one percent of high-risk children met criteria for at least one psychiatric disorder compared with 15% of low-risk children. Significant differences between groups were found for affective disorders and attention deficit disorder, and a nonsignificant trend was noted for anxiety disorder, all of which were more prevalent in the children of depressed parents.This work was supported, in part, by a W. T. Grant Foundation Faculty Scholar Award, No. 8308700.     

Relative efficacy of methylphenidate and behavior modification in hyperkinetic children: An interim report

Children reported to be hyperactive in school and with behavior difficulties at home were randomly assigned to methylphenidate, behavior therapy and placebo, or behavior therapy with methylphenidate for an 8-week period. Rating scales were obtained from teachers and parents. Independent blind observers rated childrens' classroom behavior on a weekly basis. A behavior therapy program was implemented in the home and at school. Methylphenidate dosage was individualized. Ratings of behavior deviance were significantly reduced by all treatments. However, a significant advantage for the groups receiving methylphenidate was found over the group receiving behavior therapy and placebo. No significant differences between methylphenidate alone and methylphenidate combined with behavior therapy were obtained. Global ratings of improvement done by teachers favored the combined treatment of behavior therapy and methylphenidate over behavior therapy and placebo. No differences among treatments were found in the mothers' global ratings of improvement. The results indicate that though all three treatments were effective, methylphenidate was significantly superior to behavior therapy alone.This study was supported in part by grant MH 18579, and by grant No. 3-621 from the Long Island Jewish-Hillside Medical Center.

A probability model for errors of classification. II. Particular cases

General features of a probability model for errors of classification are recapitulated as an introduction to particular cases and applications. Several models for dichotomous and nondichotomous systems are examined in sufficient detail to elaborate a procedure for dealing with any particular case. The systemO =f(T,E) has empirical reference where, as statistic or parameter, probability of occasional subclass membership is given by observation, and one seeks to recoverT andE values fromO. A procedure for relating models and data is described. Applications of the concepts and methods are illustrated for several areas of psychological research.With grateful acknowledgment to the Rockefeller Foundation; and to the United States Department of Health, Education, and Welfare, Public Health Service, for N.

Speech competence of children vulnerable to psychopathology

Verbal productivity and cohesion and reference patterns of children of schizophrenics (N=23), unipolars (N=43), bipolars (N=38), and normals (N=53) were assessed using the Rochester and Martin (1979) evaluation system. Children of all offspring groups could be discriminated from one another, with children of schizophrenics showing the most deviant speech performance across all dependent measures. Children of schizophrenics were less verbally productive and had poorer patterns of cohesion between ideas than children of normals. In addition, they produced more unclear and ambiguous references to previously mentioned ideas than did children of normals. The consistency of deviance and performance on specific dependent variables in these children at risk for schizophrenia was similar to the speech performance of thought-disordered schizophrenics. Possible explanations for these similarities were discussed and evaluated.This research was supported by grant number MH21145 from the National Institute of Mental Health and by funds from the William T. Grant Foundation. The authors would like to thank Lina Jandorf for her invaluable assistance in data collection and scoring.     

Specific fears as predictors of generalized anxiety in children

The study investigated the relationship between fear and anxiety in childhood. One hundred fifty-one children aged 6 to 11 years (mean=8.7 years) completed the Fear Survey Schedule for Children-Revised (FSSC-R) and the Revised Children's Manifest Anxiety Scale (RCMAS). Correlational analyses demonstrated that the FSSC-R and each of the fear factors were significantly correlated with each other and with the RCMAS score. A stepwise regression procedure was used to determine if the FSSC-R or any of its five factors was significantly related to scores on the RCMAS. Results indicated that Factor 1 (Failure and Criticism) accounted for 31% of the variance (p < .0001)and Factor 2 (Fear of the Unknown) accounted for an additional 1% of the variance (p < .03)in the RCMAS scores. The relationship between these results and those from a similar study with adults (Goetsch, Tishelman, & Adams, 1987), as well as how the results add to an understanding of childhood anxiety, is discussed.This study was supported by BRSG Grant S07RR0714917 from the Biomedical Research Support Grant Program, Division of Research Resources, National Institute of Health, to the Research Foundation of the State University of New York at Binghamton.     

The utility of tracking child behavior

To assess the impact of observation training and tracking of child behavior, each of 20 elementary school teachers participating in a behavior modification practicum was assigned to either an experimental or a control group. For each teacher, a disruptive, distractible child was identified as appropriate for behavioral intervention. All teachers were taught identical intervention strategies, but the two groups differed in the degree to which teachers were initially trained and subsequently required to observe and record discrete child behaviors. Multiple measures were used to assess the influence of monitoring child behaviors. These included observed child behavior, observed teacher behavior, teacher ratings, and correspondence between teacher perception and child behavior. Results showed that tracking the behavior of children had little or no effect on any measure.Support for this study was provided by the Molson Foundation and the Grant Foundation.

Polytomous IRT models and monotone likelihood ratio of the total score

In a broad class of item response theory (IRT) models for dichotomous items the unweighted total score has monotone likelihood ratio (MLR) in the latent trait. In this study, it is shown that for polytomous items MLR holds for the partial credit model and a trivial generalization of this model. MLR does not necessarily hold if the slopes of the item step response functions vary over items, item steps, or both. MLR holds neither for Samejima's graded response model, nor for nonparametric versions of these three polytomous models. These results are surprising in the context of Grayson's and Huynh's results on MLR for nonparametric dichotomous IRT models, and suggest that establishing stochastic ordering properties for nonparametric polytomous IRT models will be much harder.Hemker's research was supported by the Netherlands Research Council, Grant 575-67-034.
