Substance use, substance abuse, and LD among adolescents with a childhood history of ADHD 总被引：5，自引：0，他引：5
A clinic-referred sample of 109 children with attention-deficit/hyperactivity disorder (ADHD) was followed into adolescence for the ascertainment of alcohol and other drug use and abuse. Learning disability (reading or math) in childhood was examined as a predictor of adolescent substance use and substance use disorder for alcohol and marijuana. No statistically significant group differences for children with LD versus those without LD emerged even after using different methods to compute LD. IQ/achievement discrepancy scores were similarly not predictive of later use or abuse. However, children with ADHD who had higher IQs and higher levels of academic achievement in childhood were more likely to try cigarettes, to smoke daily, and to have their first drink of alcohol or first cigarette at an early age. Children with ADHD who had higher reading achievement scores were less likely to have later alcohol use disorder. Although these findings are necessarily preliminary, due to the small number of children interviewed, the pattern of results suggests that level of cognitive functioning--rather than discrepancy between IQ and achievement--is important for the prediction of later substance use and abuse, at least in this clinic-referred sample of children with ADHD. Further, different mechanisms of risk related to cognitive functioning may be operating for experimentation with legal drugs such as alcohol and tobacco, regular cigarette smoking, and problematic alcohol use. 相似文献

Simulated data were used to demonstrate that groups formed by imposing cut-points based on either discrepancy or low-achievement definitions of learning disabilities (LD) are unstable over time. Similar problems were demonstrated in longitudinal data from the Connecticut Longitudinal Study, where 39% of the children designated as having LD in Grade 3 changed group placement with repeated testing in Grade 5. These results show that the practice of subdividing a normal distribution with arbitrary cut-points leads to instability in group membership. Approaches to the identification of children as having LD based solely on individual test scores not linked to specific behavioral criteria lead to invalid decisions about individual children. Low-achievement definitions are not a viable alternative to IQ-discrepancy definitions in the absence of other criteria, such as the traditional exclusions and response to quality intervention. If we accept the premise of multiple classes of low achievers, then we must develop identification systems that are valid and abandon systems whose only merits are their historical precedence and convenience. 相似文献

Responsiveness to General Education Instruction as the First Gate to Learning Disabilities Identification 总被引：1，自引：0，他引：1

Most definitions of learning disabilities (LD) include a qualification that adequate general education instruction was received and the child with LD did not benefit. Rarely is this tenet assessed in either practice or research before a diagnosis is made. We review three studies that investigated children's responsiveness to general education reading instruction as an indicator of need for more intensive interventions. Adequacy of instruction was quantified by children's level and rate of progress, compared to classmates, as measured by curriculum‐based measures of oral reading fluency. We found that the response‐to‐instruction model tested was valid in that (1) children who differ from their peers on level and slope of performance (dual discrepancy) have more severe academic and behavioral problems than children who have IQ‐achievement discrepancies or low achievement; (2) children who demonstrate persistent nonresponsiveness over three years differ from other at‐risk children on reading, reading‐related, and behavioral measures; and (3) at‐risk children who participated in specially designed general education interventions had better outcomes than at‐risk children who did not participate. We conducted additional analyses to assess low achievement definitional variations and found that they lack sensitivity and coverage compared to a dual discrepancy definition. 相似文献

This replication study examined whether 158 college students classified as learning disabled (LD) who were granted course substitutions for the foreign language (FL) requirement would display significant cognitive and academic achievement differences when grouped by levels of IQ-achievement and achievement-achievement discrepancy and by level of performance on an FL aptitude test (Modern Language Aptitude Test; MLAT), phonological/orthographic processing measures, and in FL courses. The results showed that there were few differences among groups with differing levels of IQ-achievement or achievement-achievement discrepancy (i.e., < 1.0 SD, 1.0-1.49 SD, and > 1.50 SD) on MLAT and American College Testing (ACT) scores, graduating grade point average (GPA), or college FL GPA. The results also showed that between groups who scored at or above versus below the 15th percentile (i.e., < 1.0 SD) on the MLAT, there were no differences on measures of graduating GPA, college FL GPA, native language skill, ACT score, and Verbal IQ. Demographic findings showed that 44% of these petition students met a minimum IQ-achievement discrepancy criterion (> or = 1.0 SD) for classification as LD. These findings suggest that many traditional assumptions about LD and FL learning are likely to be false. 相似文献

Some researchers suggest that having a learning disability (LD) may act as a risk factor, increasing the likelihood that adolescents experience more negative outcomes in many areas of their lives. However, researchers have yet to examine in one study how having LD with and without attention deficit hyperactivity disorder (ADHD) is related to a comprehensive set of psychosocial variables across a diverse set of domains (e.g., peer, family, school, intrapersonal). The purpose of the present study was to address that limitation by comparing the perceptions of adolescents with LD (N= 230), with comorbid LD/ADHD (N= 92), and without LD or ADHD (N= 322) regarding their academic orientation, temperament, well‐being, loneliness, parental relationships, victimization, activities, and friendships. Results are consistent with the hypothesis that LD may indeed act as a risk factor increasing the likelihood of more negative outcomes. The results also indicate that for some psychosocial variables this likelihood may be increased in adolescents with comorbid LD/ADHD. The findings have important implications for stakeholders concerned about supporting adolescents with LD with and without comorbid ADHD. 相似文献

ABSTRACT— The majority of children who receive special education services meet criteria for reading disability (RD) or attention-deficit/hyperactivity disorder (ADHD), but additional research is needed to understand the long-term academic outcome of children in these groups. Individuals with RD only ( N = 71), ADHD only ( N = 66), both RD and ADHD ( N = 51), or neither disorder ( N = 118) were identified through the ongoing Colorado Learning Disabilities Research Center twin study and retested 5 years later. Results of the follow-up testing indicated that, in addition to ongoing reading difficulties, individuals with RD exhibited higher rates of academic difficulties, depression, and adolescent-onset conduct disorder. Initial ADHD status was associated with academic and social difficulties and elevated rates of nearly all comorbid disorders 5 years later. The group with comorbid RD and ADHD had more stable reading deficits than the group with RD without ADHD and exhibited greater impairment than groups with either disorder alone on outcome measures of academic functioning and social difficulties. These results suggest that individuals with both RD and ADHD are at increased risk for negative outcomes as adolescents and young adults and that when RD and ADHD co-occur, interventions should be provided for both disorders. 相似文献

阅读困难是学习困难研究中最受关注的一个领域,对整个学习困难研究领域具有重要影响。对阅读困难的有效诊断是阅读困难的研究和干预的基础。在阅读困难的诊断中,曾经广泛应用的智力—成就差异标准与模式在有效性、敏感性以及对干预的指导意义等方面存在严重不足,受到越来越多研究者和实践者的屏弃。目前,核心技能缺陷和干预—应答两类诊断标准和模式日益受到关注和采纳。我国迄今较少系统研究阅读困难的诊断标准与模式,不过,有关汉语阅读困难的初步研究鉴别出语音缺陷、快速命名缺陷和语素技能缺陷,为发展和应用核心技能标准和模式提供了重要基础,也为建立干预—应答模式提供了参考。确立汉语阅读困难诊断的核心技能与干预—应答标准与模式还有待系统和深入的研究。 相似文献

Clinical and psychoeducational data were analyzed for 119 children ages 8 to 16 years who were evaluated in a child diagnostic clinic. A learning disability (LD) was present in 70% of the children with attention-deficit/hyperactivity disorder (ADHD), with a learning disability in written expression two times more common (65%) than a learning disability in reading, math, or spelling. Children with LD and ADHD had more severe learning problems than children who had LD but no ADHD, and the former also had more severe attention problems than children who had ADHD but no LD. Further, children with ADHD but no LD had some degree of learning problem, and children with LD but no ADHD had some degree of attention problem. Results suggest that learning and attention problems are on a continuum, are interrelated, and usually coexist. 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 present study examined how vulnerability and protective factors at the individual level (child’s disabilities; patterns of attachment), and at the family level (fathers’/mothers’ affect), help explain differences in socioemotional and behavioural adjustment among children aged 8–12 years with comorbid learning disability (LD) and attention deficit hyperactivity disorder (ADHD) or with typical development. Participants were 118 father–mother–child triads: 59 couples and children with comorbid LD/ADHD and 59 couples with typically developing children. Preliminary analyses indicated significant group differences on all children’s measures and on fathers’ and mothers’ affect measures. As hypothesised, findings showed the contribution of parents’ positive and negative affect to children’s adjustment, with differences for fathers’ versus mothers’ affect. Discussion focuses on understanding the unique value of fathers’ and mothers’ affect on children’s well‐adjusted functioning. 相似文献

Childhood epilepsy is the most common paediatric neurological disorder. It is a condition with a well-documented association with cognitive, behavioural and emotional difficulties. Children with epilepsy are at increased risk of global and specific cognitive impairments. They are also at increased risk for symptoms associated with attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), depression and anxiety. The cognitive, behavioural and emotional difficulties associated with childhood epilepsy are often overshadowed by the need to treat epileptic seizures. Psychologists working in schools can provide valuable insight into the cognitive, behavioural and emotional issues faced by children with epilepsy through appropriate assessment and the recommendation of interventions which will lessen the impact of such difficulties. Educational psychologists can also help the children’s families cope with a condition with challenging psychosocial implications and provide a valuable link between school staff and supporting health professionals. 相似文献

ABSTRACTLittle is known about the characteristics of academic overachievers, children whose achievement significantly exceeds IQ. Correlates of overachievement (achievement test scores ≥ 1 SD above IQ), nondiscrepant achievement, and learning disability (LD; achievement ≥ 1 SD below IQ) were analyzed in 1,543 children (739 ADHD, 285 autism, and 519 general population), 6–16 years of age. Significant correlates of the reading and math achievement groups were diagnosis (autism greatest overachievement, ADHD greatest LD), IQ (lowest in overachievers and highest in LD), and Working Memory scores relative to the child’s IQ (close to or exceeding IQ in overachievers and lower than IQ in LD). Demographics (age, sex, race, and parent occupation) and parent and teacher ratings of psychopathology (e.g., behavior problems, anxiety, and depression) and personality characteristics (e.g., motivation and self-confidence) did not contribute significantly more to predicting overachievement and LD beyond that explained by IQ, diagnosis, and working memory. These findings suggest an underlying neurobiological etiology for both overachievement and LD. 相似文献

Learning disabilities (LD) are common in clinical disorders, but no study has compared the relative prevalence in referred children with different diagnoses. Our sample comprised 949 children (6 to 16 years). LD percentages were highest for bipolar disorder (79%), ADHD combined type (71%), autism (67%), ADHD inattentive type (66%), and spina bifida (60%). Children with oppositional-defiant disorder, adjustment disorder, anxiety, and depression had relatively low LD percentages (18–19%). LD in written expression was twice as common as LD in reading or math. Findings indicate that children with neurogenetic disorders should be assessed for possible LD because of the high potential yield and the need to intervene educationally if learning problems exist. 相似文献

We reviewed the records of 42 consecutive cases of children with Tourette Syndrome (TS) who had IQs above 70, and contrasted the reading, reading comprehension, math, and spelling quotients with IQ scores to determine how many would meet criteria for a learning disability. The mean IQ of the 35 males and 7 females was 94.4 and was higher than the mean math score (82.8), spelling score (90.4), reading score (87.4), and reading comprehension score (85.3). Using a 1.5 standard deviation discrepancy, 51% met criteria for learning disability in at least one academic area; 21% had a 2-standard-deviation discrepancy. Children with TS frequently have learning disabilities, and assessment of academic achievement should be a routine aspect in the evaluation of such children. 相似文献

This research investigates the peer-related social functioning of 291 children (185 males, 106 females), aged from 8 years to 17 years and 8 months diagnosed with varying Attention-Deficit/Hyperactivity Disorder (ADHD) subtypes (i.e., Predominantly Inattentive m I, Combined m C) with and without comorbid learning disabilities (LD). All were administered the Interpersonal Relationships Questionnaire which is comprised of six reliable and valid measures: Social Desirability, Interpersonal Difficulties, Social Self-Concept, Social Self-Confidence, Preference for Solitude, and Social Interaction Anxiety. Results revealed that neither Gender, Age, nor Social Desirability were significantly associated with children's self-reports. Pearson correlations demonstrated that the strength and magnitude of associations between self-reports of interpersonal relationships varied according to group status. With the exception of Preference for Solitude, analyses of variance revealed significant differences in self-reports by group, as related to the presence or absence of LD, particularly for the ADHD-C+LD compared to the ADHD-I+LD group. Psychoeducational and clinical implications for understanding the functional and discriminant significance of social impairment among children with varying ADHD subtypes with comorbid LD are discussed in light of these research findings. 相似文献

Private Speech of Learning Disabled and Normally Achieving Children in Classroom Academic and Laboratory Contexts 总被引：3，自引：0，他引：3
Learning disabled (LD) children are often targets for cognitive-behavioral interventions designed to train them in effective use of a self-directed speech. The purpose of this study was to determine if, indeed, these children display immature private speech in the naturalistic classroom setting. Comparisons were made of the private speech, motor accompaniment to task, and attention of LD and normally achieving classmates during academic seatwork. Setting effects were examined by comparing classroom data with observations during academic seatwork and puzzle solving in the laboratory. Finally, a subgroup of LD children symptomatic of attention-deficit hyperactivity disorder (ADHD) was compared with pure LD and normally achieving controls to determine if the presumed immature private speech is a function of a learning disability or externalizing behavior problems. Results indicated that LD children used more task-relevant private speech than controls, an effect that was especially pronounced for the LD/ADHD subgroup. Use of private speech was setting- and task-specific. Implications for intervention and future research methodology are discussed. 相似文献

Academic accommodations for students experiencing disabilities are increasingly available at postsecondary institutions. More studies of the efficacy of accommodations for student success are warranted, however. Given the increased gender gap in university participation, more focus on the unique impact of gender is also needed. Using a sample of students registered with Access and Inclusion Services with learning disabilities (LD), attention-deficit/hyperactivity disorder (ADHD), and combined LD/ADHD at a Canadian undergraduate university (N = 661), we explored the impact of gender on academic performance and accommodation usage. Next, we examined how gender intersected with the impact of academic accommodations on academic performance. Women, on average, demonstrated better academic performance. Academic strategies and assistive technologies were not associated with higher academic performance. However, testing accommodations (extended time and environmental accommodations) were positively associated with academic performance for men with LD or ADHD, but not for the combined group LD/ADHD. For the former two, the more tests accommodated, the higher the academic performance. Furthermore, this gender association was most prominent for students experiencing ADHD. Interpretations and policy recommendations related to these findings are presented. 相似文献

This study assesses information processing and memory functioning in 50 children diagnosed with Attention Deficit Hyperactive Disorder (ADHD) with and without learning disabilities (LD). Mode of presentation (visual vs. auditory), type of memory processing (immediate, short-term, and long-term), and order of recall (ordered vs. unordered) were assessed using the Learning Efficiency Test-II (LET-II). Both groups demonstrated difficulty with auditory ordered recall and lost substantial information from immediate memory to short-term and long-term memory stores. The ADHD/LD group also demonstrated more difficulty with ordered recall than the ADHD only group. While there were no differences between the two groups in regard to immediate recall, the ADHD/LD group demonstrated more problems transferring information into short-term and long-term memory stores than the ADHD only group. Verbal interference effects significantly decreased retention for both visual and auditory processing. Results indicate that ADHD alone presents significant problems in information processing, but the comorbid effects of a learning disability further intensify the negative impact of ADHD. © 1996 John Wiley & Sons, Inc. 相似文献

The Behavior Assessment Scale for Children – Second Edition (BASC‐2) was administered to 108 parents and 37 teachers of children with epilepsy (mean age of 10.6 years; 51% female, 49% male). Results demonstrated high mean scores on the Atypicality, Attention Problems, Withdrawal, and Adaptive Skills scales and a high percentage of At‐Risk or Clinically Significant scores on the majority of scales. Ratings were correlated with level of functioning, age of onset, and number of antiepileptic medications. In addition, children with poor seizure control had higher ratings on the Depression, Somatization, and Withdrawal scales, and children with temporal lobe seizures had higher scores on the Depression scale. These results confirm a high rate of behavioral concerns in children with epilepsy. © 2008 Wiley Periodicals, Inc. 相似文献
