Postsecondary attention-deficit/hyperactivity disorder and deliberate practice: Study time,study quality,and self-perceptions

The current study examined study habits of postsecondary students with attention-deficit/hyperactivity disorder (ADHD) through the theoretical context of deliberate practice. The responses of participants with and without ADHD were compared on a survey of study time, study quality, and self-perceptions of study habits, as well as a measure of test anxiety. Groups were equivalent on reports of study time and time spent in other activities, percentage of classes they attend, use of conducive study environments, and planning of studying. Despite similar study behaviors, ADHD participants were more likely to feel unprepared for tests, reported significantly higher test anxiety, and had lower grade point averages. Regardless of ADHD status, the majority of study participants were not implementing deliberate practice behaviors, with the exception of class attendance, and study times fell far below recommended levels. Findings provided evidence that emulating the study behaviors of peers is not sufficient for students with ADHD to experience similar outcomes.     

Cognitive and academic abilities associated with symptoms of attention-deficit/hyperactivity disorder: a comparison between subtypes in a Greek non-clinical sample

The study assessed cognitive and academic performance of children demonstrating teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/Impulsivity [H/I]) in a representative sample of, largely untreated, Greek elementary school students (N?=?923). A battery of tests assessing short-term memory (STM), sustained attention, executive functions (EFs), reading and math skills were administered. Significant deficits in EFs and STM were restricted to the groups of students displaying inattention symptoms and were only marginally elevated among students showing hyperactivity/impulsivity symptoms alone, in comparison to their non-symptomatic peers. A similar pattern of group differences was observed on tests assessing word- and text-level reading skills. Impaired performance on sustained attention tasks was less evident. Among students who manifested inattention symptoms, those who also showed impaired reading skills presented more severe EFs deficits than typically achieving students. Results demonstrated a close link between EFs, other than inhibition and set-shifting, everyday symptoms of inattention, and achievement in math and word-level reading skills.     

Children with attention-deficit/hyperactivity disorder: A review of the literature on social skills deficits

Social interactions between children with Attention-Deficit/Hyperactivity Disorder (AD/HD) and their teachers, peers, and parents are discussed. The extent to which these interactions may be termed problematic may depend on the social skills deficits displayed by this population. Although the general trend in the liternature has been to examine and describe children with deficient social skills, changing the focus to children with AD/HD who are not experiencing these difficulties may prove beneficial. A review of the previous literature is discussed, as well as suggestions for practice and future research needs.

Links between preschool children's prosocial skills and aggressive conduct problems: The contribution of ADHD symptoms

The aim was to examine the relationship between prosocial behavior and conduct problems, especially aggression, in early childhood. In Phase 1 of the study, teachers reported on 93 3–5-year-old children's prosocial behavior and psychological problems, using a screening instrument, the Strengths and Difficulties Questionnaire (SDQ). In Phase 2, 65 parents completed the SDQ and were interviewed in depth, using a clinical interview, the Preschool Age Psychiatric Assessment (PAPA). Children with clinically significant symptoms of conduct disorder and ADHD were significantly less prosocial than other children. However, aggressive conduct symptoms were unrelated to prosocial behavior, once symptoms of ADHD were taken into account. The findings suggest that problems in regulating activity and attention interfere with prosocial development.     

The experiences of and attitudes toward non-pharmacological interventions for attention-deficit/hyperactivity disorder used in school settings: a systematic review and synthesis of qualitative research

School-based non-pharmacological interventions are an important part of the treatment of attention-deficit/hyperactivity disorder (ADHD). We aimed to systematically review qualitative literature relating to the experience of and attitudes towards school-based non-pharmacological interventions for ADHD. Systematic searches of 20 electronic databases were undertaken. Reviewers screened titles, abstracts and full reports of studies, before extracting data and critically appraising 33 included papers. Studies were synthesised using meta-ethnographic methods. Four-key interrelated themes were identified: (1) individualising interventions, (2) structure of interventions, (3) barriers to effectiveness, (4) perceived moderators and impact of interventions. The perceived effectiveness of interventions used in school settings is reported to vary. Therefore, flexible, tailored interventions ought to hold potential. However, highly individualised interventions may negatively affect children with ADHD. Findings point to the need for school-based interventions to take into account the wider school context, as well as core symptoms of ADHD.     

Introduction to the special issue on genes, environment, and reading

This introduction to the special issue on Genes, Environment, and Reading presents an overview of the background for behavior- and molecular-genetic research on dyslexia and individual differences across the normal range. The general methods, questions addressed, and selected results are summarized for each of the papers in the order of their presentation in the special issue. Concluding comments reflect on the influence of environmental range on estimates of genetic and environmental influences, and the future of behavior- and molecular-genetic research on reading.     

Linkages between child abuse and attention-deficit/hyperactivity disorder in girls: behavioral and social correlates

OBJECTIVE: The objectives of this study were to examine whether girls with attention-deficit/hyperactivity disorder (ADHD) are at increased risk of having histories of abuse and to assess whether the presence of an abuse history may constitute a distinct subgroup of youth with ADHD. METHOD: We examined rates and correlates of child abuse in an ethnically and socioeconomically diverse sample of girls with attention-deficit/hyperactivity disorder (ADHD; n=140) and a matched comparison sample of girls without ADHD (n=88), all aged 6-12 years. A thorough chart review reliably established documented rates of physical and sexual abuse in both samples. RESULTS: There were significantly higher rates of abuse for girls with ADHD (14.3%) than for the comparison sample (4.5%), with most of the abuse found in girls with the Combined as opposed to the Inattentive type. Higher rates of externalizing behaviors (including objective observations in a research summer camp) and peer rejection (indexed through peer sociometric nominations) characterized the subgroup of girls with ADHD with abuse histories compared to the subgroup without such histories, with moderate to large effect sizes. Subgroup differences regarding internalizing problems and cognitive deficits did not emerge. Findings regarding peer rejection were explained, in part, by higher rates of observed aggressive behavior in the abused subgroup. CONCLUSIONS: The findings raise important questions about the possible etiologic and/or exacerbating role of abusive trauma in a subgroup of children with ADHD.     

Longitudinal twin study of early literacy development: Preschool through Grade 1

Grade 1 literacy skills of twin children in Australia (New South Wales) and the United States (Colorado) were explored in a genetically sensitive design (N = 319 pairs). Analyses indicated strong genetic influence on word and nonword identification, reading comprehension, and spelling. Rapid naming showed more modest, though reliable, genetic influence. Phonological awareness was subject to high nonshared environment and no reliable genetic effects, and individual measures of memory and learning were also less affected by genes than nonshared environment. Multivariate analyses showed that the same genes affected word identification, reading comprehension, and spelling. Country comparisons indicated that the patterns of genetic influence on reading and spelling in Grade 1 were similar, though for the U.S. but not the Australian children new genes came on stream in the move from kindergarten to Grade 1. We suggest that this is because the more intensive kindergarten literacy curriculum in New South Wales compared with Colorado, consistent with the mean differences between the two countries, means that more of the genes are “online” sooner in Australia because of accelerated overall reading development.     

Visualisation to support children with attention-deficit/hyperactivity disorder learning to solve mathematical word problems: A randomised controlled trial

This randomised controlled trial experimental study compared the effectiveness of using two different types of visualisation – self-constructed visualisation (SCV) and passively received visualisation (PRV) – to help children with attention-deficit/hyperactivity disorder (ADHD) solve mathematical word problems. While SCV refers to drawings that children create to help solve given word problems, PRV refers to pre-made images that accompany word problems. Twenty children with ADHD in Kuwait, aged nine to 11 years, were randomly assigned to either the SCV or PRV group, where they were taught to use either SCV or PRV to solve word problems across 20 daily one-to-one sessions. The results showed that regardless of the visualisation type, children's word problem-solving ability significantly improved. Children with ADHD should thus be encouraged to use visualisation to help make the word problem-solving process more accessible to them.     

EEG analysis of children with attention-deficit/hyperactivity disorder and comorbid reading disabilities

This study investigated electroencephalographic differences between two groups of children with attention-deficit/hyperactivity disorder, combined type, with reading disabilities (ADHD + RD) or without (ADHD) and typical control participants. Twenty participants were included in each group. All participants were between the ages of 8 and 12 years, and groups were matched on age and gender. The electroencephalographic (EEG) was recorded during an eyes-closed resting condition from 21 monopolar derivations, which were clustered into nine regions for analysis. The EEGs were Fourier-transformed to provide absolute and relative power estimates for the delta, theta, alpha, and beta bands. Ratio coefficients were also calculated for the theta/alpha and theta/beta ratios. Compared with controls, the clinical groups demonstrated the increased slow-wave and reduced fast-wave activity commonly reported in the ADHD literature. The ADHD + RD group had more relative theta, less relative alpha, and a higher theta/alpha ratio than the ADHD group. A number of hemispheric differences were also found in the delta and alpha bands. These results suggested that some of the EEG divergences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability that is independent of the EEG divergences found in ADHD.     

Associations between abuse/neglect and ADHD from childhood to young adulthood: A prospective nationally-representative twin study

Child maltreatment has consistently been found to be associated with attention deficit/hyperactivity disorder (ADHD). However, the robustness of this association and the direction of the link between maltreatment and ADHD remain unclear. We used data from the Environmental Risk (E-Risk) Longitudinal Twin Study, a cohort of 2232 British twins, to investigate the associations between exposure to abuse/neglect and ADHD in childhood and in young adulthood, and to test their robustness and specificity. We also aimed to test longitudinal associations between abuse/neglect and ADHD from childhood to young adulthood, controlling for confounders. Results indicated strong associations between abuse/neglect and ADHD in childhood and also in young adulthood. In childhood, the association was concentrated among children with comorbid conduct disorder. Longitudinal analyses showed that childhood ADHD predicted abuse/neglect in later years. This association was again concentrated among individuals with comorbid conduct disorder. Abuse/neglect in childhood was not associated with later ADHD in young adulthood after adjusting for childhood ADHD. Our study does not provide support of a causal link between child abuse/neglect and adult ADHD but highlights the possibility of a long-term effect of disruptive behaviors on the risk for experiencing abuse/neglect. These findings emphasize the need for clinicians treating people with ADHD, especially those with comorbid conduct disorder, to be aware of their increased risk for experiencing abuse/neglect. Interventions aimed at reducing risks of abuse/neglect should also focus on the environment of individuals with disruptive behaviors.     

The relation between reading ability and morphological skills: Evidence from derivational suffixes

The English orthography represents both phonemes and morphemes, implying that sensitivity to each of these units could play a role in the acquisition of decoding skills. This study offers some new evidence about sensitivity to morphemes and the decoding skills of American children in grades three to six. It focuses on knowledge of derivational suffixes, which is examined with sentence completion and sentence acceptability tasks that manipulate the suffixes in real words (e.g., electric, electricity) and nonsense derived forms (e.g., froodly, froodness). Both written and spoken materials are considered over the course of two experiments in which the children also received various reading tests, as well as tests of phonological awareness, vocabulary and intelligence. The results indicate that knowledge of derivational suffixes increases with grade level, along with decoding ability and phoneme awareness. Path analyses further reveal that, although there is a consistent correlation between performance on the derivational suffix materials and phoneme awareness and decoding ability, performance on the derivational suffix materials makes an independent and increasing contribution to decoding ability throughout the higher elementary grades.     

Comorbidity of reading disability and attention-deficit/hyperactivity disorder: differences by gender and subtype

This study used a community sample of 494 twins with a reading disability (223 girls, 271 boys) and 373 twins without a reading disability (189 girls, 184 boys) to assess the relation between reading disability (RD) and attention-deficit/hyperactivity disorder (ADHD). Symptoms of DSM-III and DSM-IV ADHD were classified into symptoms of inattention and symptoms of hyperactivity-impulsivity (H/I). Results indicated that individuals with RD were more likely than individuals without RD to meet criteria for ADHD and that the association between RD and ADHD was stronger for symptoms of inattention than for symptoms of H/I. Parents and teachers reported similar rates of ADHD, suggesting that ADHD symptoms were pervasive across settings and were not solely attributable to academic frustration. Analyses of possible gender differences revealed that RD was significantly associated with inattention in both girls and boys but associated with H/I only in boys. This difference may provide a partial explanation for the discrepancy between the gender ratio obtained in referred (approximately 4 boys to 1 girl) and nonreferred (1.2 to 1.5 boys to 1 girl) samples of individuals with RD. Specifically, the hyperactive and impulsive behaviors exhibited by boys with RD may be more disruptive than the inattentive behaviors exhibited by girls and may therefore precipitate more frequent referrals for clinical attention.     

The second deficit: An investigation of the independence of phonological and naming-speed deficits in developmental dyslexia

An increasing body of dyslexia researchdemonstrates, in addition to phonologicaldeficits, a second core deficit in theprocesses underlying naming speed. Thehypothesized independence of phonologicalawareness and naming-speed variables inpredicting variance in three aspects of readingperformance was studied in a group of 144severely-impaired readers in Grades 2 and 3. Stepwise regression analyses were conducted onthese variables, controlling for the effects ofSES, age, and IQ. Results indicated thatphonological measures contribute more of thevariance to those aspects of reading skill thatinvolve decoding or word attack skills;naming-speed measures contribute more to skillsinvolved in word identification. Subtypeclassification findings were equally supportiveof the independence of the two deficits: 19%of the sample had single phonological deficits;15% had single naming-speed deficits; 60% had double-deficits; and 6% could not be classified. The implications of these findingsfor diagnosis and intervention are discussed.     

The associations between teacher-child relationships and academic skills: A longitudinal study among Chinese preschool children

The current study followed a sample of 656 Chinese preschool children to examine reciprocal associations between teacher-child relationships and children’s academic skills by testing three cross-lagged models: the relationship-driven model, the child-driven model, and the reciprocal model. Fifty-nine head teachers reported teacher-child relationships, and children’s academic skills were assessed at three time points during the 2nd and 3rd preschool year. Results showed that the reciprocal model was the best fit in explaining the associations between teacher-child relationships and children’s academic skills (math achievement, character recognition and executive function), and the child-driven model was the best fit in explaining the relation between teacher-child relationships and children’s receptive vocabulary. The results contribute to understand the dynamic relations between teacher-child relationships and children's academic skills in the Chinese preschool context. Implications for educational practices are discussed.     

Estimated prevalence of attention-deficit/ hyperactivity disorder symptoms among college freshmen: gender, race, and rater effects

Group differences and prevalence rates for attention-deficit/hyperactivity disorder (ADHD) symptoms in a matched sample of college freshmen (n = 956) and their parents (n = 956) were investigated for gender and race (African American and Caucasian) effects using current self-report and retrospective parent-report ratings. On self-report, compared to female students, male students displayed higher mean scores on subscales and lower rates for reporting symptom totals beyond DSM-IV thresholds for the three subtypes of ADHD. Mean differences in ADHD symptoms were not apparent for race. However, African American students displayed higher rates for reporting symptom totals beyond DSM-IV thresholds for all subtypes. On retrospective parent report, male students and Caucasian students displayed higher mean scores on all scales and higher rates for reporting symptom totals beyond DSM-IV thresholds for all subtypes. Prevalence rates varied by gender and race on self-report and parent report. Prevalence was examined based on combined data of self-report and parent report and using age-adjusted cutoff criteria. Findings and implications are discussed.     

Learning disabilities and risk-taking behavior in adolescents: a comparison of those with and without comorbid attention-deficit/hyperactivity disorder

Risk-taking behavior includes alcohol and drug use, delinquency, acts of aggression, sexual activity, and so on. Many studies have explored the relationship between adolescents and risk-taking behavior; however, only a few studies have examined this link in adolescents with learning disabilities (LD) or attention-deficit/hyperactivity disorder (ADHD). The purpose of the present study was to address that limitation by comparing the risk-taking behavior of adolescents with LD (n=230), with comorbid LD/ADHD (n=92), and without LD or ADHD (n=322) on their substance use, engagement in major and minor delinquency, acts of aggression, sexual activity, and gambling activities. The study also investigated whether psychosocial variables (e.g., well-being) may act as mediating variables that help explain between-group differences. Results suggest that it is a combination of the LD and the secondary psychosocial characteristics that explains why adolescents with LD and comorbid LD/ADHD more frequently engage in some risk-taking behavior.
