Research findings regarding the relationship of social skills deficits and behavioral characteristics associated with attention-deficit hyperactivity disorder (ADHD) among kindergarten-age children are presented. The Preschool and Kindergarten Behavior Scales (PKBS) were utilized to identify the social skills attributes of young children with significant ADHD characteristics. An ADHD target group (N = 95) was constructed by selecting participants from a large nationwide sample who were rated by their teachers as being in the highest 5% on the PKBS Attention Problems/Overactive subscale. A matched non-ADHD comparison group (by gender and age) of 95 children was developed through a randomized block procedure using the same nationwide sample. The ADHD group was rated as having significantly poorer social skills than the comparison group, and could be classified with a very high degree of accuracy based on discriminant function analysis of their social skills scores. Although exhibiting comparative deficits in all social skill areas, the ADHD participants were especially lacking in social cooperation skills: the ability to follow rules, structure, and important social expectations of both children and adults. Children who were rated high in ADHD characteristics were between five and six times more likely than the comparison children to be rated as having significant deficits in social skills. Implications of these findings for assessment and treatment of young children are discussed. © 1998 John Wiley & Sons, Inc.  相似文献

This study addressed two issues: first, whether parental reports contribute information over and above a standardized psychometric assessment, and second, whether parental reports of everyday cognitive functioning might be useful in distinguishing between children with reading disabilities (RD), attention-deficit/hyperactivity disorder (ADHD), and combined ADHD + RD. Parent-reported information on 159 children with learning or attention problems was obtained using a questionnaire called the Parent Ratings of Everyday Cognitive and Academic Abilities (PRECAA). Psychometric information used for comparison included the Woodcock-Johnson Psychoeducational Battery-Revised, the Bruininks-Oseretsky Test of Motor Proficiency-Short Form, the Vocabulary and Block Design subtests of the Wechsler Intelligence Scale for Children, 3rd edition, and the Developmental Test of Visual-Motor Integration. The PRECAA was found to be sensitive to group differences between children with RD and children with ADHD and combined ADHD + RD. Its inclusion resulted in a significant increase in the number of children correctly classified compared to the use of psychometric measures alone. The PRECAA correctly classified more children (66%) than did the standard psychometric measures (50%). In fact, a very high percentage of children with ADHD (81%) were correctly classified using the PRECAA. These findings suggest that the PRECAA may be a useful aid to clinicians in the identification of children with learning and attention problems.  相似文献

This study attempted to determine whether children with the combined subtype of attention-deficit/hyperactivity disorder (ADHD) have impairments in cognitive functioning and motor skills. The specific effect of the comorbidity of learning disabilities (LD) was also investigated. A battery of cognitive tests was administered to 26 children with a clinical diagnosis of ADHD-combined subtype (ADHD/C), to 24 children with ADHD/C with a comorbid diagnosis of LD (ADHD/C+LD), and to 102 participants without disabilities, all between ages 7 and 10. The testing battery consisted of tasks assessing memory, visuospatial and verbal abilities, and fine motor skills. In general, the test results of children with ADHD/C were poorer than those of the control group but better than the results of children with a combined ADHD/C+LD diagnosis (with the exception of motor skills). The predictive accuracy of the testing battery tasks in children with ADHD/C and ADHD/C+LD was examined. The results of a standard procedure of discriminant function analyses revealed that the measures correctly classified 73.6% of the children.  相似文献

The study presented here investigated the performance of children with learning, psychiatric, and attentional disabilities on the Stroop Color and Word Test. Forty‐three children diagnosed with a full battery of tests as learning disabled (LD [reading]) in grades K through 6 were matched on age, gender, ethnicity, and grade with 43 normal controls. They were also matched with groups of 43 children with psychiatric disorders and 43 children with attentional problems. All subjects were given the Stroop test, which took about 4 minutes per subject. The results indicated clear differences between the groups, with the LD and the psychiatric/attention deficit/hyperactivity disorder (ADHD) groups generating unique profiles different from the normal controls. The children with LD showed slower reading speed and less interference, while the subjects with ADHD and diagnoses showed impairment only on the Color‐Word score. A discriminant analysis using the three basic Stroop scales was able to significantly differentiate the LD group from the non–learning‐disabled (NLD) group (89%) and the LD group from a joint Psychiatric/ADHD group (86%). However, results were poorer for differentiating a joint LD/ADHD group from the NLD group (68%) and the LD from the ADHD group (59%). © 2002 Wiley Periodicals, Inc.  相似文献

Methylphenidate (MPH) often ameliorates attention-deficit/hyperactivity disorder (ADHD) behavioral dysfunction according to indirect informant reports and rating scales. The standard of care behavioral MPH titration approach seldom includes direct neuropsychological or academic assessment data to determine treatment efficacy. Documenting "cool" executive-working memory (EWM) and "hot" self-regulation (SR) neuropsychological impairments could aid in differential diagnosis of ADHD subtypes and determining cognitive and academic MPH response. In this study, children aged 6 to 16 with ADHD inattentive type (IT; n = 19) and combined type (n = 33)/hyperactive-impulsive type (n = 4) (CT) participated in double-blind placebo-controlled MPH trials with baseline and randomized placebo, low MPH dose, and high MPH dose conditions. EWM/ SR measures and behavior ratings/classroom observations were rank ordered separately across conditions, with nonparametric randomization tests conducted to determine individual MPH response. Participants were subsequently grouped according to their level of cool EWM and hot SR circuit dysfunction. Robust cognitive and behavioral MPH response was achieved for children with significant baseline EWM/SR impairment, yet response was poor for those with adequate EWM/ SR baseline performance. Even for strong MPH responders, the best dose for neuropsychological functioning was typically lower than the best dose for behavior. Findings offer one possible explanation for why long-term academic MPH treatment gains in ADHD have not been realized. Implications for academic achievement and medication titration practices for children with behaviorally diagnosed ADHD will be discussed.  相似文献

In this study of the project DyAdd, implicit learning was investigated through two paradigms in adults (18–55 years) with dyslexia (n?=?36) or with attention deficit/hyperactivity disorder (ADHD, n?=?22) and in controls (n?=?35). In the serial reaction time (SRT) task, there were no group differences in learning. However, those with ADHD exhibited faster RTs compared to other groups. In the artificial grammar learning (AGL) task, the groups did not differ from each other in their learning (i.e., grammaticality accuracy or similarity choices). Further, all three groups were sensitive to fragment overlap between learning and test-phase items (i.e., similarity choices were above chance). Grammaticality performance of control participants was above chance, but that of participants with dyslexia and participants with ADHD failed to differ from chance, indicating impaired grammaticality learning in these groups. While the main indices of AGL performance, grammaticality accuracy and similarity choices did not correlate with the neuropsychological variables that reflected dyslexia-related (phonological processing, reading, spelling, arithmetic) or ADHD-related characteristics (executive functions, attention), or intelligence, the explicit knowledge for the AGL grammar (i.e., ability to freely generate grammatical strings) correlated positively with the variables of phonological processing and reading. Further, SRT reaction times correlated positively with full scale intelligence quotient (FIQ). We conclude that, in AGL, learning difficulties of the underlying rule structure (as measured by grammaticality) are associated with dyslexia and ADHD. However, learning in AGL is not related to the defining neuropsychological features of dyslexia or ADHD. Instead, the resulting explicit knowledge relates to characteristics of dyslexia.  相似文献

Several forms of assessment tools, including behavioral rating scales and objective tests such as the Continuous Performance Test (CPT), can be used to measure inattentive and hyperactive/impulsive behaviors associated with Attention-Deficit/Hyperactivity Disorder (ADHD). However, research with school-age children has shown that the correlations between parent ratings, teacher ratings, and scores on objective measures of ADHD-characteristic behaviors are modest at best. In this study, we examined the relations between parent and teacher ratings of ADHD and CPT scores in a sample of 65 preschoolers ranging from 50 to 72 months of age. No significant associations between teacher and parent ratings of ADHD were found. Parent-ratings of both inattention and hyperactivity/impulsivity accounted for variance in CPT omission errors but not CPT commission errors. Teacher ratings showed evidence of convergent and discriminant validity when entered simultaneously in a hierarchical regression. These tools may be measuring different aspects of inattention and hyperactivity/impulsivity.  相似文献

The purpose of the study was to develop a battery of tests with which to identify parents who have potential for abuse and/or neglect of children. The samples were composed of abusive men and women parents or parent figures matched with controls.The variables, parents' background, personality, child rearing attitudes, social networks and parent-child interactions, were tested by interview questionnaire, videotaped behavioral observation, and physiologic response.Both bivariate and multivariate data analysis were utilized including zero order correlations, factor analysis, path analysis, and discriminant analysis.The tests sharpley differentiated between groups on background, empathy, antecedents to early attachment, ways of handling irritating child behaviors, child rearing attitudes, parent-child communication, reference persons, and physiologic response. Abusive parents maintained higher heart rates, had less heart rate variability, higher electrodermal magnitude response and lower recovery times.  相似文献

We examined the information processing capabilities of children diagnosed with the inattentive subtype of attention-deficit/hyperactivity disorder (ADHD) who had been characterized as having a sluggish cognitive tempo. Children referred for school-related problems (n = 81) and nonreferred community controls (n = 149) participated. Of the referred children, 24 met criteria for ADHD, 42 met criteria for reading disability (RD), and 9 of these were comorbid for RD and ADHD. Children with ADHD differed from those without ADHD on a visual search task but not on an auditory processing task; the reverse was true for children with RD. Decomposition of the visual search task into component operations demonstrated that children in the ADHD group had a slow processing rate that was not attributable to inattention. The children with ADHD were not globally poor at information processing or inattentive, but they demonstrated diminished speed of visual processing.  相似文献

Children with attention deficit hyperactivity disorder (ADHD) were examined on four subtests of the Test of Everyday Attention for Children (TEA‐Ch) when on and off stimulant medication. Performance was assessed relative to 18 individually age‐matched controls. Children with ADHD performed significantly worse on TEA‐Ch measures when off compared to when on stimulant medication. This was found in both predominantly inattentive (n = 6) and combined inattentive and hyperactive‐impulsive (n = 12) subtypes. The age‐matched controls significantly improved with repeated testing on most TEA‐Ch measures. Significant differences were found between the unmedicated children with ADHD and age‐matched controls on sustained attention (Score! and Walk Don’t Walk) and attention control measures (Same and Opposite Worlds). When the ADHD group was on stimulant medication, with the exception of the Walk Don’t Walk subtest, no significant differences were found between them and the age‐matched controls. Unlike the TEA‐Ch subtests, the significant differences between the two groups on the Test of Word Reading Efficiency (TOWRE) subtests remained when attentional status was altered in the children with ADHD. The study supports further investigations of the TEA‐Ch as a measure sensitive to changes in stimulant medication in children with ADHD.  相似文献

The study compared early literacy of Israeli children aged five to six years with and without attention deficit hyperactivity disorder (ADHD), contrasted parental writing mediation in the two groups and tested the relations between parents’ mediation characteristics and children’s early literacy skills. Each of 62 parent‐child dyads (32 with ADHD) was videotaped at home while writing words. Videotapes were transcribed and analysed for mediation (specific writing task measures, emotional measures typical of problem‐solving tasks, and general measures of interactions). Children’s early literacy (word writing, letter knowledge and phonological awareness) was assessed at home. Results showed that children with ADHD already exhibited lower literacy achievements at ages five to six compared to their peers without ADHD. Parents of children with ADHD scored lower than parents of children without ADHD on the writing‐specific, emotional and general mediation measures. In both groups, the specific writing mediation measures correlated significantly with children’s early literacy. More emotional mediation measures correlated significantly with children’s early literacy in the ADHD than in the non‐ADHD group. Discussion focused on parent‐child writing interactions as a context of early literacy development among young children with ADHD.  相似文献

This study assessed rates of learning disabilities (LD) by several psychometric definitions in children with epilepsy and identified risk factors. Participants (N = 173, ages 8-15 years) completed IQ screening, academic achievement testing, and structured interviews. Children with significant head injury, chronic physical conditions, or mental retardation were excluded. Using an IQ-achievement discrepancy definition, 48% exceeded the cutoff for LD in at least one academic area; using low-achievement definitions, 41% to 62% exceeded cutoffs in at least one academic area. Younger children with generalized nonabsence seizures were at increased risk for math LD using the IQ-achievement discrepancy definition; age of seizure onset and attention-deficit/hyperactivity disorder (ADHD) were risk factors for reading and math LD using low-achievement definitions. Writing was the most common domain affected, but neither ADHD nor seizure variables reliably identified children at risk for writing LD. Although children with earlier seizure onset, generalized nonabsence seizures, and comorbid ADHD appear to be at increased risk for some types of LD by some definitions, these findings largely suggest that all children with epilepsy should be considered vulnerable to LD. A diagnosis of epilepsy (even with controlled seizures and less severe seizure types) should provide sufficient cause to screen school-age children for LD and comorbid ADHD.  相似文献

Although behavioral evidence provides support for the notion that attention deficit-hyperactivity disorder (ADHD) is related to central nervous system dysfunction, there is little direct evidence to reveal which neurometabolic systems or brain structures are involved. Recent magnetic resonance imaging (MRI) studies suggest that, compared to nondisabled controls, ADHD children may have a smaller right frontal region. Morphometric analysis of MRI scans was used in this exploratory study to determine whether correlated regional variation might exist in the corpus callosum of children with ADHD. While all MRI scans were judged to be clinically normal, morphometric analysis revealed that, compared to nondisabled controls, ADHD children had a smaller corpus callosum, particularly in the region of the genu and splenium, and in the area just anterior to the splenium. Interhemispheric fibers in these regions interconnect the left and right frontal, occipital, parietal, and posterior temporal regions. These results suggest that subtle differences may exist in the brains of children with ADHD and that deviations in normal corticogenesis may underlie the behavioral manifestations of this disorder.  相似文献

Self‐reported internalizing symptoms of seriously emotionally disturbed (SED) and regular education students in grades 4–6 were compared using the Internalizing Symptoms Scale for Children. All participants were African American and from an urban public school district in the Southeastern United States. Each of the two study groups consisted of 50 participants (35 boys, 15 girls) who were matched by gender and socioeconomic status. The SED group reported significantly higher levels of internalizing distress than the regular education group. In contrast to previous findings, there was no significant gender difference in self‐reported internalizing symptomatology in the present study. A discriminant function analysis found that the ISSC scores were able to correctly classify 91% of the participants into their respective educational group. Results of this study provide additional evidence of the construct validity of the ISSC, a recently developed and unique self‐report measure. Results are discussed in terms of future research needs and educational/clinical practice with students who have emotional and behavioral disorders. © 1999 John Wiley & Sons, Inc.  相似文献

The double-deficit model has been examined primarily in relation to reading. We investigated whether children classified according to the double-deficit model would exhibit differences in other neuropsychological domains. Children referred for learning problems (N = 188), ages 7 to 11, were classified by double-deficit subtype. Only three of the four groups predicted by the model could be identified. There were no group differences in IQ or attention problems. The three groups showed different neuropsychological profiles, involving functional domains other than reading and language. Differences also emerged in nonverbal low-level information processing. The double-deficit group was generally most severely affected. The double-deficit groupings identify children with different neuropsychological profiles and variation in the efficiency of basic online information processing, extending beyond the oral and written language domain.  相似文献

The possible utility of Wechsler's Deterioration Index (WDI) in analyzing children's Wechsler Intelligence Scale for Children-Revised (WISC-R) results was explored in this study. Clinical records of children with learning disabilities (LD) and children with attention deficit-hyperactivity disorder (ADHD) were reviewed to determine if the WDI predicted the presence or severity of the disorders. The ages of the children ranged from 6 to 14. In two independent samples of children with LD (n = 35 and n = 26), the WDI did not predict LD status or severity. The LD samples were mostly male--85% and 57%, respectively. However, the WDI scores did significantly distinguish children with ADHD (n = 10) from nondisabled children (n = 10). The results were cross-validated on an independent sample of children with ADHD (n = 17) when compared to non-ADHD children (n = 22) who experienced significant behavioral difficulties. The ADHD samples were also mostly male--90% and 89%, respectively. The WDI classified only 59% of the children with ADHD and 86% of the non-ADHD children correctly. It is recommended that the WDI be considered a developmental index rather than a deterioration index in children. It is also recommended that significant WDI elevation (greater than .20) be considered to raise the question of ADHD, rather than simply yielding a diagnosis of ADHD.  相似文献

The present study explored the relationship between the intelligence of young adults and their performance on the Test of Variables of Attention (TOVA). The study also examined whether significant differences existed between adults with and without attention-deficit/ hyperactivity disorder (ADHD) on TOVA errors of omission, errors of commission, mean correct response time, and variability, as well as on performance on the freedom from distractibility (FD) factor on the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Seventy-nine adults participated in the study, including 17 with ADHD and 62 college students without ADHD. Pearson product-moment correlations indicated that none of the correlations between Full Scale IQ (FSIQ) and TOVA variables were significant. Analysis of variance results revealed that adults with ADHD made more errors of omission on the TOVA than did controls. Between-group differences were not found on the remaining dependent variables.  相似文献

This study examined the mechanisms underlying verbal learning in children with and without attention-deficit/hyperactivity disorder (ADHD), none of whom had reading disabilities. Children with ADHD were compared to typically developing children on both process and product scores from the California Verbal Learning Test for Children. The findings indicated that children with ADHD initially learned the same number of words as controls but showed weaknesses recalling the words after delays, suggesting that children with ADHD are less efficient learners. Regardless of ADHD status, boys and girls performed differently. Boys used semantic clustering less frequently and recalled fewer words from the middle region of the list than girls; girls also outperformed boys in terms of overall performance, despite lower verbal IQ scores. These findings show that children with ADHD can exhibit unexpected weaknesses in learning even without a formal learning disability. Gender differences in verbal learning are also illustrated.  相似文献
